based on computer vision and machine learning<\/span><\/p>\n<p style=\"color: #ffffff;\">Graduate Student : Ying-Hsien Chen<\/p>\n<p style=\"color: #ffffff;\">Advisor: Chih-Hsien Huang<\/p>\n<p style=\"color: #ffffff;\">Abstract:<\/p>\n<p style=\"color: #ffffff;\">Motion capture technology using wearable devices and cameras is essential for tracking and recording athletes&#8217; movements. However, most wearable devices cannot operate in the water, and manually analyzing the swimming data from the videos is time-consuming. Hence, this study aims to develop an intelligent swimming recording system that could quantify the swimming results of the butterfly stroke and integrate them into a replay video to offer comprehensive and accurate information to swimmers and coaches. First, this work builds a data collection setup that could simultaneously capture the complete scene of a 25 m track by stitching the videos of 8 cameras (four under and four above the water). After that, this study developed a swimmer recognition model by applying transfer learning to 120,031 labeled images while using YOLOv4 as the pre-trained model. Next, this work used the six bounding box coordinates produced by the recognition model to calculate the split time of 15m\/25m, the number of strokes, and the underwater dolphin kicking angles. Then, the accelerometer readings were synchronized using the timing and number of butterfly strokes. Finally, the developed system would integrate the analyzed data, three-axis acceleration readings, and the underwater dolphin kick trajectories into a replay video. This study filmed 85 videos of 25-meter butterfly strokes of five participants to examine the efficacy of the proposed system. The swimmer recognition model achieved an Intersection over Union (IoU) of 81.51%, and the mean absolute error (MAE) of the split time was 0.36 seconds. Besides, the F1-score of identifying strokes was 97.85%, and the Pearson correlation of the kicking angle detection was 0.64. The entire processing time from identification to producing a playback video was four and a half minutes for a 30-second video. Hence, the proposed system should be considered a valuable tool for providing prompt and comprehensive quantified and visual feedback to the swimmers and coaches after each practice.<\/p>\n<\/div><\/div><\/div><\/div><\/div><div class=\"fusion-widget-area fusion-widget-area-1 fusion-content-widget-area\"><style type=\"text\/css\">.fusion-widget-area-1 {padding:0px 0px 0px 0px;}.fusion-widget-area-1 .widget h4 {color:#ffffff;}.fusion-widget-area-1 .widget .heading h4 {color:#ffffff;}<\/style><div class=\"fusion-additional-widget-content\"><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-7{width:100% !important;margin-top : 0px;margin-bottom : 0px;}.fusion-builder-column-7 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.824%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-7{width:100% !important;order : 0;}.fusion-builder-column-7 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-7{width:100% !important;order : 0;}.fusion-builder-column-7 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-8 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">.fusion-accordian  #accordion-196-2 .panel-title a .fa-fusion-box{ color: #ffffff;}.fusion-accordian  #accordion-196-2 .panel-title a .fa-fusion-box:before{ font-size: 16px; width: 16px;}.fusion-accordian  #accordion-196-2 .panel-title a{font-size:16px;}.fusion-accordian  #accordion-196-2 .fa-fusion-box { background-color: #212934;border-color: #212934;}.fusion-accordian  #accordion-196-2 .panel-title a:hover, #accordion-196-2 .fusion-toggle-boxed-mode:hover .panel-title a { color: #ffc107;}.fusion-accordian  #accordion-196-2 .panel-title .active .fa-fusion-box,.fusion-accordian  #accordion-196-2 .panel-title a:hover .fa-fusion-box { background-color: #ffc107!important;border-color: #ffc107!important;}<\/style><div class=\"accordian fusion-accordian\"><div class=\"panel-group\" id=\"accordion-196-2\"><div class=\"fusion-panel panel-default\"><div class=\"panel-heading\"><h4 class=\"panel-title toggle\"><a aria-expanded=\"false\" aria-controls=\"7d5d72fbf7c8441d7\" role=\"button\" data-toggle=\"collapse\" data-parent=\"#accordion-196-2\" data-target=\"#7d5d72fbf7c8441d7\" href=\"#7d5d72fbf7c8441d7\"><span class=\"fusion-toggle-icon-wrapper\" aria-hidden=\"true\"><i class=\"fa-fusion-box\" aria-hidden=\"true\"><\/i><\/span><span class=\"fusion-toggle-heading\">Design, simulation, and characterization of a novel optical piezoelectric micromechanical ultrasonic transducer (OpMUT)<\/span><\/a><\/h4><\/div><div id=\"7d5d72fbf7c8441d7\" class=\"panel-collapse collapse \"><div class=\"panel-body toggle-content fusion-clearfix\">\n<p style=\"color: #ffffff;\"><img decoding=\"async\" class=\"lazyload size-full wp-image-3142 alignright\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%27554%27%20height%3D%27418%27%20viewBox%3D%270%200%20554%20418%27%3E%3Crect%20width%3D%27554%27%20height%3D%27418%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-orig-src=\"http:\/\/catsweb.ee.ncku.edu.tw\/wordpress\/wp-content\/uploads\/2024\/09\/\u7d39\u5049\u5b78\u9577\u78a9\u8ad6\u7167.png\" alt=\"\" width=\"554\" height=\"418\" \/>Thesis Title: Design, simulation, and characterization of a novel optical piezoelectric micromechanical ultrasonic transducer (OpMUT)<\/p>\n<p style=\"color: #ffffff;\">Graduate Student : Shao-Wei Wu<\/p>\n<p style=\"color: #ffffff;\">Advisor: Chih-Hsien Huang<\/p>\n<p style=\"color: #ffffff;\">Abstract:<\/p>\n<p style=\"color: #ffffff;\">In this study, to overcome the high impedance and electromagnetic interference susceptibility of piezoelectric micromechanical ultrasonic transducers (pMUTs) due to the use of piezoelectric materials, silicon photonic components, which are less susceptible to electromagnetic interference and have high sensitivity, were combined with pMUTs. The silicon photonic component adopted in this study is the optical ring resonator, which is easier to integrate with pMUTs. The combination of the optical ring resonator and pMUT has been successfully used to study the novel optical piezoelectric micromechanical transducer (OpMUT). The working principle of OpMUT is different from that of pMUT. When the pMUT receives ultrasound, causing the thin film to vibrate, the radius of the ring waveguide in the optical ring resonator changes, thereby changing the light output intensity. The light is then converted into voltage through a photodiode and a transimpedance amplifier circuit. This study uses the finite element method and numerical analysis to optimize the optical ring resonator&#8217;s width, radius, and placement. After that, we compare the signal-to-noise ratio (SNR) and noise equivalent pressure (NEP) of the proposed OpMUT with state-of-the-art pMUT at the same resonance frequency. When the width and radius of the ring waveguide are 400 nm and 35.45 \u00b5m, the SNR of a 150 kHz OpMUT is about 59 dB @ 1Pa, and the NEP is 0.0007 Pa. It is significantly better than the competitor, who has an SNR of 37 dB @ 1Pa and NEP of 0.0014 Pa.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-8{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-8 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-8{width:100% !important;order : 0;}.fusion-builder-column-8 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-8{width:100% !important;order : 0;}.fusion-builder-column-8 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-9 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><div class=\"fusion-widget-area fusion-widget-area-2 fusion-content-widget-area\"><style type=\"text\/css\">.fusion-widget-area-2 {padding:0px 0px 0px 0px;}.fusion-widget-area-2 .widget h4 {color:#ffffff;}.fusion-widget-area-2 .widget .heading h4 {color:#ffffff;}<\/style><div class=\"fusion-additional-widget-content\"><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-9{width:100% !important;margin-top : 0px;margin-bottom : 0px;}.fusion-builder-column-9 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-9{width:100% !important;order : 0;}.fusion-builder-column-9 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-9{width:100% !important;order : 0;}.fusion-builder-column-9 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-10 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">.fusion-accordian  #accordion-196-3 .panel-title a .fa-fusion-box{ color: #ffffff;}.fusion-accordian  #accordion-196-3 .panel-title a .fa-fusion-box:before{ font-size: 16px;

However, current acoustic volumetric displays can only present small and simple shapes due to the speed limitations and the distortion caused by the instability of the suspended object&#8217;s trajectory. Previously, some studies have discussed increasing the imaging size in the vertical plane. Hence, this study aims to raise the imaging size of the horizontal plane by applying an edge deceleration method to increase the average speed of the entire route since the suspending objects usually fly out when changing direction. First, the authors built an acoustic levitation system to realize three kinds of edge deceleration distributions and filmed the object with a high-speed camera. After that, this study identified and analyzed the coordinates of the suspended object to analyze the speed distribution and the degree of distortion. Besides, we captured images with longer exposure time to compare the visual performance of the persistence of vision. Compared to the traditional fixed interval distribution, the maximum frame rate and achievable size for square, triangle, and hexagon patterns increase by 45.5%, 25.1%, and 53.1%, respectively. In parallel with it, the imaging distortion of displaying square, triangle, and hexagon shapes decreases by 73.3%, 81.1%, and 80.5%, respectively. Consequently, the proposed edge deceleration method successfully increased the planar imaging size and quality of the acoustic hologram. A three-dimensional acoustic volumetric display capable of producing large patterns should be feasible by using more transducer arrays and combining different levitating position-selecting methods.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-10{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-10 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-10{width:100% !important;order : 0;}.fusion-builder-column-10 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-10{width:100% !important;order : 0;}.fusion-builder-column-10 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-11 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><div class=\"fusion-widget-area fusion-widget-area-3 fusion-content-widget-area\"><style type=\"text\/css\">.fusion-widget-area-3 {padding:0px 0px 0px 0px;}.fusion-widget-area-3 .widget h4 {color:#ffffff;}.fusion-widget-area-3 .widget .heading h4 {color:#ffffff;}<\/style><div class=\"fusion-additional-widget-content\"><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-11{width:100% !important;margin-top : 0px;margin-bottom : 0px;}.fusion-builder-column-11 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-11{width:100% !important;order : 0;}.fusion-builder-column-11 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-11{width:100% !important;order : 0;}.fusion-builder-column-11 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-12 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">.fusion-accordian  #accordion-196-4 .panel-title a .fa-fusion-box{ color: #ffffff;}.fusion-accordian  #accordion-196-4 .panel-title a .fa-fusion-box:before{ font-size: 16px;

Recently, the erudition speed of carbon bricks in one blast furnace was abnormal and will shorten its lifespan. Hence, this study proposed a machine learning model to address this issue by predicting hearth temperature and finding the critical operation parameters. Besides, because the operation parameters of a blast furnace were numerous (1470 in this study), this work applied Explainable AI (XAI) for feature selection to enhance model performance. First, this research optimized the training setups of the Long Short-Term Memory (LSTM) model and reduced the parameters to 150 through the Pearson correlation. After that, this work proposed a progressive training method to reduce the RMSE of the testing set from 34.2 \u00b0C to 17.5 \u00b0C. Next, the authors trained prediction models for six temperature sensing positions and calculated the SHAP values of each feature. Then, this work ranked the features based on their SHAP values and retained each prediction model with top-ranked features. The RMSE of the retrained models improved from 17.8 \u00b0C, 21.9 \u00b0C, 19.4 \u00b0C, 25.2 \u00b0C, 13.6 \u00b0C, and 8.1 \u00b0C to 11.1 \u00b0C, 15.6 \u00b0C, 12.1 \u00b0C, 17.7 \u00b0C, 6.7 \u00b0C, and 5.6 \u00b0C. Besides, retraining the model with SHAP-selected features successfully reduced prediction delays from more than predicting days to less than it. In parallel, the correlations between rising and falling periods of practical and predicted temperatures increased, respectively.

Research shows that doing strength training at any age could reduce the impact of these issues. Strength training beginners usually require coaches&#8217; intervention to ensure motion quality and reduce the risk of injury. However, it is essential and unavoidable to practice after coaching classes. Therefore, improving the quality and safety of training in the absence of a coach is critical. This study developed an intelligent barbell coaching system with a real-time mode that could immediately diagnose the issue and provide feedback after each squat. Besides, a replay mode allows users to examine their previous squats and check their comments. First, four key features of the barbell squat were collected, including bending angles of the body, dorsiflexion, ratio of knee\/hip movements, and the wobble of the barbell. This work collects 8151 squats from 77 subjects and categorizes them as good squats and six issues. Then, we trained the diagnosis models with three machine-learning architectures, including 1D-CNN, LSTM, and Random Forest. In addition, this research applied the SHAP method to improve the accuracy of predicting each issue and reduce the computation time by feature selection. The F1-Score of the six issues reached 86.86%, 69.01%, 77.42%, 90.74%, 95.83% and 100%, respectively. Besides, the diagnosis time of each squat is less than 0.5 s. Finally, this work examined the efficacy of the proposed system with two groups of subjects trained with and without the system. Consequently, the scores of those trained with the system showed significant improvement, either rated by the system or the professional weightlifting coach.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-15{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-15 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-15{width:100% !important;order : 0;}.fusion-builder-column-15 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-15{width:100% !important;order : 0;}.fusion-builder-column-15 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-16 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">.fusion-accordian  #accordion-196-6 .panel-title a .fa-fusion-box{ color: #ffffff;}.fusion-accordian  #accordion-196-6 .panel-title a .fa-fusion-box:before{ font-size: 16px; width: 16px;}.fusion-accordian  #accordion-196-6 .panel-title a{font-size:16px;}.fusion-accordian  #accordion-196-6 .fa-fusion-box { background-color: #212934;border-color: #212934;}.fusion-accordian  #accordion-196-6 .panel-title a:hover, #accordion-196-6 .fusion-toggle-boxed-mode:hover .panel-title a { color: #ffc107;}.fusion-accordian  #accordion-196-6 .panel-title .active .fa-fusion-box,.fusion-accordian  #accordion-196-6 .panel-title a:hover .fa-fusion-box { background-color: #ffc107!important;border-color: #ffc107!important;}<\/style><div class=\"accordian fusion-accordian\"><div class=\"panel-group\" id=\"accordion-196-6\"><div class=\"fusion-panel panel-default\"><div class=\"panel-heading\"><h4 class=\"panel-title toggle\"><a aria-expanded=\"false\" aria-controls=\"bbd1cbb57f45c2d47\" role=\"button\" data-toggle=\"collapse\" data-parent=\"#accordion-196-6\" data-target=\"#bbd1cbb57f45c2d47\" href=\"#bbd1cbb57f45c2d47\"><span class=\"fusion-toggle-icon-wrapper\" aria-hidden=\"true\"><i class=\"fa-fusion-box\" aria-hidden=\"true\"><\/i><\/span><span class=\"fusion-toggle-heading\">Reconstructing 2D gas temperature distribution with deep neural networks<\/span><\/a><\/h4><\/div><div id=\"bbd1cbb57f45c2d47\" class=\"panel-collapse collapse \"><div class=\"panel-body toggle-content fusion-clearfix\">\n<p style=\"color: #ffffff; text-align: left;\"><img decoding=\"async\" class=\"lazyload wp-image-3151 alignright\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%27640%27%20height%3D%27508%27%20viewBox%3D%270%200%20640%20508%27%3E%3Crect%20width%3D%27640%27%20height%3D%27508%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-orig-src=\"http:\/\/catsweb.ee.ncku.edu.tw\/wordpress\/wp-content\/uploads\/2024\/09\/\u693f\u5143\u5b78\u9577\u78a9\u8ad6\u7167.png\" alt=\"\" width=\"640\" height=\"508\" \/>Thesis Title: Reconstructing 2D gas temperature distribution with deep neural networks<\/p>\n<p style=\"color: #ffffff;\">Graduate Student : Chun-Yuan Chen<\/p>\n<p style=\"color: #ffffff;\">Advisor\uff1aChih-Hsien Huang<\/p>\n<p style=\"color: #ffffff;\">Abstract:<\/p>\n<p style=\"color: #ffffff;\">Acoustic tomography is considered a promising technique for visualizing gas temperature distributions. Typically, reconstruction algorithms for acoustic tomography utilize the speed of sound along multiple paths within the region of interest to reconstruct the temperature map. To improve the accuracy of reconstruction, increasing the number of iterations is often necessary, but this process can be time-consuming.<\/p>\n<p style=\"color: #ffffff;\">Therefore, this study proposes a convolutional neural network (CNN) to train a machine learning model that can reconstruct gas temperature distributions from sound speed measurements. By adjusting the labels and loss functions within the neural network, six different models were successfully trained to reconstruct gas temperature distributions. Two models were trained using ideal temperature distributions, three using temperature distributions derived from reconstruction algorithms, and one using specific temperature data extracted from ideal temperature distributions. The performance of these six models was evaluated based on temperature distributions from 13 different peak temperature locations, and their ability to track hotspots was compared to existing reconstruction methods. Additionally, the 2D visualization performance was assessed using three different temperature distributions: one similar to the training data and two completely different.<\/p>\n<p style=\"color: #ffffff;\">Results indicate that models trained with ideal gas temperature distributions could more accurately track hotspots. Models trained with reconstructed gas temperature distributions demonstrated similar performance to the selected reconstruction algorithms. When the input sound speed differed from the training data, models trained with ideal gas temperature distributions showed poorer results compared to models trained with reconstructed temperature distributions. This suggests that the proposed model can effectively learn the relationship between temperature distributions and sound speed from reconstruction algorithms.<\/p>\n<p style=\"color: #ffffff;\">Finally, the execution time of the model was 0.109 seconds, representing a 96% reduction compared to the iterative reconstruction algorithms. Therefore, the proposed reconstruction method should be considered a reliable and efficient approach for 2D gas temperature distribution reconstruction.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-16{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-16 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-16{width:100% !important;order : 0;}.fusion-builder-column-16 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-16{width:100% !important;order : 0;}.fusion-builder-column-16 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-17 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">@media only screen and (max-width:1000px) {.fusion-title.fusion-title-4{margin-top:15px!important;

The lifespan of a blast furnace directly impacts the overall cost of steel production, and it is influenced by various factors, including the thickness of the cooling plates and furnace carbon bricks. Among these, the carbon brick thickness is the most crucial. In recent years, the ability to adjust furnace operations in response to upcoming conditions has become increasingly important. This study presents a machine learning model designed to predict furnace hearth temperature, addressing the issue of rapid carbon brick erosion observed in China Steel\u2019s No. 4 blast furnace.<\/p>\n<p style=\"color: #ffffff;\">The thickness of carbon bricks is calculated from furnace hearth temperature using a specific formula. As steel demand increases, the furnace must remain operational for extended periods, causing its temperature to rise gradually. When the furnace hearth temperature exceeds historical highs, it signals a thinning of the carbon bricks. Adjusting the temperature without affecting steel output is challenging, but if temperature trends can be predicted in advance, more efficient measures can be taken.<\/p>\n<p style=\"color: #ffffff;\">In this study, principal component analysis (PCA) and Pearson correlation coefficients were used to verify the number of features in the dataset. PCA revealed the complexity of different feature sets, and highly correlated features were removed based on Pearson coefficients.<\/p>\n<p style=\"color: #ffffff;\">To demonstrate the feasibility of predicting furnace hearth temperature, a temperature classifier was trained using the random forest algorithm. The classifier achieved 95% accuracy on the test set. Finally, a long short-term memory (LSTM) model was developed to predict furnace hearth temperature using operational data from the blast furnace. To further optimize the temperature prediction model, a new training method was proposed, and the optimal combination of input and output lengths was identified to minimize model loss. The LSTM model achieved a mean squared error (MSE) of 0.00939, compared to a baseline MSE of 0.0615 using untrained average temperature estimates.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-17{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-17 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-17{width:100% !important;order : 0;}.fusion-builder-column-17 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-17{width:100% !important;order : 0;}.fusion-builder-column-17 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-18 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">.fusion-accordian  #accordion-196-8 .panel-title a .fa-fusion-box{ color: #ffffff;}.fusion-accordian  #accordion-196-8 .panel-title a .fa-fusion-box:before{ font-size: 16px;

Temperature is a crucial parameter for ensuring the quality of products in manufacturing enterprises. For instance, in blast furnaces, the quality of steel is closely related to the distribution of gas temperature within the furnace. Monitoring high-temperature gases and tracking the location of hotspots is essential for improving productivity.<\/p>\n<p style=\"color: #ffffff;\">Most existing acoustic-based reconstruction algorithms are developed under the assumption of relatively uniform temperature distributions, with limited discussion on their capability to track peak temperatures or hotspots. This study proposes and demonstrates a specialized acoustic tomography reconstruction method tailored for highly concentrated gas temperature distributions. The proposed method can effectively visualize and measure peak temperatures with an accuracy of 5.89% and track the movement of hotspots to new locations.<\/p>\n<p style=\"color: #ffffff;\">AT reconstructs two-dimensional gas temperature distributions using the speed of sound along multiple paths on a plane. Thus, accurate reconstruction of the temperature map relies on both the reconstruction method and precise speed of sound estimation. However, due to the lack of critical information, such as methods for estimating time-of-flight (TOF) or sound speed, the results reported in existing literature are difficult to reproduce. Therefore, this study proposes and demonstrates a new technique to enhance the accuracy of acoustic platforms used for sound speed measurement. Using the proposed method, sound speed accuracy of \u00b13% to \u00b15% was achieved in environments with critical temperature distributions. Subsequently, the two-dimensional temperature maps reconstructed using the measured sound speeds matched the results from thermocouple arrays.<\/p>\n<\/div><\/div><\/div><\/div><\/div><div class=\"fusion-widget-area fusion-widget-area-5 fusion-content-widget-area\"><style type=\"text\/css\">.fusion-widget-area-5 {padding:0px 0px 0px 0px;}.fusion-widget-area-5 .widget h4 {color:#ffffff;}.fusion-widget-area-5 .widget .heading h4 {color:#ffffff;}<\/style><div class=\"fusion-additional-widget-content\"><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-18{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-18 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-18{width:100% !important;order : 0;}.fusion-builder-column-18 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-18{width:100% !important;order : 0;}.fusion-builder-column-18 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-19 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">.fusion-accordian  #accordion-196-9 .panel-title a .fa-fusion-box{ color: #ffffff;}.fusion-accordian  #accordion-196-9 .panel-title a .fa-fusion-box:before{ font-size: 16px; width: 16px;}.fusion-accordian  #accordion-196-9 .panel-title a{font-size:16px;}.fusion-accordian  #accordion-196-9 .fa-fusion-box { background-color: #212934;border-color: #212934;}.fusion-accordian  #accordion-196-9 .panel-title a:hover, #accordion-196-9 .fusion-toggle-boxed-mode:hover .panel-title a { color: #ffc107;}.fusion-accordian  #accordion-196-9 .panel-title .active .fa-fusion-box,.fusion-accordian  #accordion-196-9 .panel-title a:hover .fa-fusion-box { background-color: #ffc107!important;border-color: #ffc107!important;}<\/style><div class=\"accordian fusion-accordian\"><div class=\"panel-group\" id=\"accordion-196-9\"><div class=\"fusion-panel panel-default\"><div class=\"panel-heading\"><h4 class=\"panel-title toggle\"><a aria-expanded=\"false\" aria-controls=\"7401a3afca67c9661\" role=\"button\" data-toggle=\"collapse\" data-parent=\"#accordion-196-9\" data-target=\"#7401a3afca67c9661\" href=\"#7401a3afca67c9661\"><span class=\"fusion-toggle-icon-wrapper\" aria-hidden=\"true\"><i class=\"fa-fusion-box\" aria-hidden=\"true\"><\/i><\/span><span class=\"fusion-toggle-heading\">A Novel ADE System with Tunable Droplet Size and Ejection Height<\/span><\/a><\/h4><\/div><div id=\"7401a3afca67c9661\" class=\"panel-collapse collapse \"><div class=\"panel-body toggle-content fusion-clearfix\">\n<p><span style=\"color: #ffffff; background-color: rgba(255, 255, 255, 0); font-family: var(--body_typography-font-family); font-size: var(--body_typography-font-size); font-style: var(--body_typography-font-style,normal); font-weight: var(--body_typography-font-weight); letter-spacing: var(--body_typography-letter-spacing);\"><img decoding=\"async\" class=\"lazyload wp-image-3148 alignright\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%27640%27%20height%3D%27508%27%20viewBox%3D%270%200%20640%20508%27%3E%3Crect%20width%3D%27640%27%20height%3D%27508%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-orig-src=\"http:\/\/catsweb.ee.ncku.edu.tw\/wordpress\/wp-content\/uploads\/2024\/09\/\u4e16\u5f18\u5b78\u9577\u78a9\u8ad6\u7167.png\" alt=\"\" width=\"640\" height=\"508\" \/>Thesis Title: <\/span><span style=\"background-color: rgba(255, 255, 255, 0); color: #ffffff; font-family: var(--body_typography-font-family); font-size: var(--body_typography-font-size); font-style: var(--body_typography-font-style,normal); font-weight: var(--body_typography-font-weight); letter-spacing: var(--body_typography-letter-spacing);\">A Novel ADE System with Tunable Droplet Size and Ejection Height<\/span><\/p>\n<p style=\"color: #ffffff;\">Graduate Student : Shih-Hung Shen<\/p>\n<p style=\"color: #ffffff;\">Advisor\uff1aChih-Hsien Huang<\/p>\n<p style=\"color: #ffffff;\">Abstract:<\/p>\n<p style=\"color: #ffffff;\">Acoustic droplet ejection (ADE) has been proven to move liquids in droplet form from a container to mid-air. However, the droplet sizes produced using the traditional ADE setups are proportional to their heights if the physical framework is unchanged. This limitation obstructs further employment of ADE technology since having the exact sizes of droplets at a specific location or different sizes at different locations is required for many applications. To overcome this limitation and enable more possible applications of ADE, this study proposed an innovative ADE configuration that could manipulate the size and height of the ADE droplets with only electrical signals. To achieve this, a low-voltage driving period and a pinhole structure were added to create a water mound before ejection. First, simulations were conducted to validate the proposed method and find the parameters of the novel ADE setup. After that, a driving circuit featuring a high-voltage pulser and a field-programmable gate array was built. Besides, a 3D spherical resin model was printed to focus the acoustic wave on the water surface, and a cover with a pinhole was added to create water mound. To observe the behavior of the droplets, a recording system and detection algorithm were developed to capture and identify the dimension\/height of the droplets, respectively. Finally, the proposed ADE configuration successfully manipulated the droplet size at the same ejecting height under three driving voltages (65 V, 70 V, and 75 V) and pinhole diameters (3.7 mm, 4 mm, and 4.4 mm).<\/p>\n<\/div><\/div><\/div><\/div><\/div><div class=\"fusion-widget-area fusion-widget-area-6 fusion-content-widget-area\"><style type=\"text\/css\">.fusion-widget-area-6 {padding:0px 0px 0px 0px;}.fusion-widget-area-6 .widget h4 {color:#ffffff;}.fusion-widget-area-6 .widget .heading h4 {color:#ffffff;}<\/style><div class=\"fusion-additional-widget-content\"><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-19{width:100% !important;margin-top : 0px;margin-bottom : 15px;}.fusion-builder-column-19 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-19{width:100% !important;order : 0;}.fusion-builder-column-19 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-19{width:100% !important;order : 0;}.fusion-builder-column-19 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-20 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">@media only screen and (max-width:1000px) {.fusion-title.fusion-title-5{margin-top:15px!important;

It offers advantages such as high resolution and non-contact interaction, making it suitable for integration with VR\/AR technologies or 3C products.<\/p>\n<p style=\"color: #ffffff;\">Current ultrasonic haptic technologies are typically realized through sensor modules composed of traditional transducers. However, these modules are bulky and difficult to integrate with portable devices. This study proposes the use of piezoelectric micromachined ultrasonic transducers (pMUT) to replace traditional transducers, significantly reducing the overall size. A major advantage of pMUTs over capacitive micromachined ultrasonic transducers (cMUTs) is that pMUTs do not require a DC bias for operation, resulting in lower power consumption and better compatibility with portable products.<\/p>\n<p style=\"color: #ffffff;\">In this research, both disk analysis models and finite element models were employed to simulate the design of a pMUT with a resonant frequency of 40 kHz. Lead zirconate titanate (PZT) was selected as the piezoelectric layer for the pMUT structure. Three fabrication methods were explored: RF sputtering, pulsed laser deposition, and sol-gel deposition. Through adjustments to the annealing parameters, PZT films with excellent crystallinity and piezoelectric properties were successfully prepared. These films were then applied in the full pMUT fabrication process. The device utilized a silicon-on-insulator (SOI) wafer as the substrate and structure layer, with sequential deposition of the bottom electrode, PZT, and top electrode, followed by back-etching to create a cavity.<\/p>\n<p style=\"color: #ffffff;\">The fabricated pMUT was analyzed using a laser Doppler vibrometer (LDV), which confirmed a resonant frequency close to the target of 40 kHz. When driven by a pulse signal, the pMUT generated a sound pressure of 0.227 Pa, as measured by a high-frequency microphone. Simulations of pMUT arrays demonstrated the ability to generate sound pressure sufficient to produce tactile sensations, indicating potential applications of pMUTs in ultrasonic haptic technology.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-21{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-21 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-21{width:100% !important;order : 0;}.fusion-builder-column-21 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-21{width:100% !important;order : 0;}.fusion-builder-column-21 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-22 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">.fusion-accordian  #accordion-196-11 .panel-title a .fa-fusion-box{ color: #ffffff;}.fusion-accordian  #accordion-196-11 .panel-title a .fa-fusion-box:before{ font-size: 16px;

However, most algorithm development in this field relies on simulated sound speed data.<\/p>\n<p style=\"color: #ffffff;\">This research focuses on designing a hardware platform that provides researchers with an experimental setup for studying related algorithms and hardware components. The thesis details the experimental setup, considerations for component and circuit design, and testing of different circuits to achieve higher signal quality. By using shielded cables to transmit sound waves, the signal-to-noise ratio (SNR) improved by 1.8 times. Additionally, with the custom-designed isolated power supply board, the SNR increased by 5.3 times. The experimental environment utilizes 12 sets of ultrasonic sensors for sound wave transmission and reception. The designed transmission and reception circuit allows the same sensor to both transmit and receive sound waves, with a maximum receiving angle of \u00b1150 degrees.<\/p>\n<p style=\"color: #ffffff;\">Finally, temperature measurement experiments were conducted using this platform, and the temperature distribution within the target area was reconstructed using an algorithm developed by the laboratory. The system\u2019s accuracy was verified with 37 external thermocouples. The results from the thermocouples matched well with the temperature measurements obtained from the system, across various heat source experiments.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-22{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-22 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-22{width:100% !important;order : 0;}.fusion-builder-column-22 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-22{width:100% !important;order : 0;}.fusion-builder-column-22 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-23 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">.fusion-accordian  #accordion-196-12 .panel-title a .fa-fusion-box{ color: #ffffff;}.fusion-accordian  #accordion-196-12 .panel-title a .fa-fusion-box:before{ font-size: 16px;

In reality, ultrasound is a mechanical wave transmitted through a medium and has low attenuation in water. This allows it to pass through suspended particles with minimal impact on the organisms in aquaculture environments. Compared to optical imaging, ultrasound imaging is nearly unaffected by light, water color, or turbidity, offering significant advantages for development in smart aquaculture.<\/p>\n<p style=\"color: #ffffff;\">This thesis proposes an artificial intelligence-based ultrasound image recognition system for white shrimp. The goal is to leverage ultrasound technology to provide images that were previously unattainable due to environmental factors, and to automatically determine the number, location, and length of white shrimp within the area. This system aims to help aquaculture farmers optimize feeding strategies, achieving intelligent, high-efficiency, environmentally friendly, and sustainable aquaculture practices.<\/p>\n<p style=\"color: #ffffff;\">The YOLOv4 object detection model was employed to train on ultrasound images of white shrimp, and the study examined the impact of different training datasets on shrimp image recognition. The model was used to detect the location of shrimp in the target area, and a scoring algorithm based on Spectral Clustering was applied to process the detection results. Ultimately, the system was able to successfully determine the number, location, and length of white shrimp in the area. According to experimental results, the YOLOv4 model achieved a mean average precision (mAP) of 98.93% on the test set, with an average Intersection over Union (IOU) of 78.47%. Additionally, the system was able to predict shrimp quantities with an accuracy of 97.3%.

It utilizes laser pulses of specific wavelengths to rapidly heat biological tissues, causing them to expand and contract, which in turn generates ultrasound waves. These ultrasound waves are then converted into electrical signals by sensors, and the signals are used to reconstruct 2D or 3D images based on the position of the laser beam, the distribution of the sensor array, and the speed and travel time of the sound waves.<\/p>\n<p style=\"color: #ffffff;\">Current PAI systems face limitations because the piezoelectric films and metal electrodes used in traditional ultrasound sensors are often opaque, necessitating the laser source to avoid the sensor, complicating miniaturization efforts. This poses significant challenges when developing wearable systems. Therefore, this research focuses on improving the ultrasound sensor by developing a flexible, transparent sensor using polyvinylidene fluoride (PVDF) as the piezoelectric material and indium tin oxide (ITO) for the electrodes. The developed sensor achieved an 86.51% 3dB bandwidth and a center frequency of 6.831 MHz, with a longitudinal resolution of 265\u03bcm and a lateral resolution of 400\u03bcm. The sensor was tested under prolonged bending conditions, showing stable performance within reasonable bending limits. Due to the transparency of both PVDF and ITO, the laser can directly pass through the sensor, allowing the laser source, sensor, and target tissue to be aligned along the same path. This significantly enhances the feasibility of integrating PAI systems into wearable devices.<\/p>\n<p style=\"color: #ffffff;\">A 532nm Nd<\/p>\n<p style=\"color: #ffffff;\">laser was used to test the imaging capabilities of the sensor. A single-point laser scanning method was employed, with a single sensor receiving the signals. These signals were amplified and sent to a digital-to-analog converter before being stored on a computer for 2D or 3D image reconstruction. The reconstructed images were compared with a custom-designed model, showing longitudinal and lateral positioning errors of 0.94% and 1.66%, respectively, for imaging in water. The imaging depth reached 36mm in water and 15mm in epoxy resin models. The experimental results demonstrate that the developed flexible, transparent ultrasound sensor can adhere to human tissue surfaces with high flexibility for long-term physiological signal monitoring and can be applied for shallow vein imaging, showing potential for wearable device development.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-24{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-24 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-24{width:100% !important;order : 0;}.fusion-builder-column-24 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-24{width:100% !important;order : 0;}.fusion-builder-column-24 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-25 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">.fusion-accordian  #accordion-196-14 .panel-title a .fa-fusion-box{ color: #ffffff;}.fusion-accordian  #accordion-196-14 .panel-title a .fa-fusion-box:before{ font-size: 16px;

Most non-contact gesture recognition systems today rely on vision-based techniques, which can be significantly affected by changes in lighting conditions and raise privacy concerns due to the use of image capture devices. Ultrasonic gesture recognition, on the other hand, is not constrained by these issues. However, existing ultrasonic gesture recognition systems often rely on the Doppler effect and are primarily used for recognizing dynamic gestures. This research proposes a method for recognizing static gestures using time-frequency analysis to generate spectrograms from ultrasonic signals.<\/p>\n<p style=\"color: #ffffff;\">In this study, four commercially available 40kHz ultrasonic sensors were used for signal transmission and data reception. The received ultrasonic signals were converted to digital signals using an analog-to-digital converter, and then transformed into time-frequency intensity images using short-time Fourier transform (STFT). Two deep learning models were developed and trained, and the most suitable model was selected. By optimizing various parameters of the model, the gesture recognition accuracy was improved by approximately 5%, reaching 98.07%. The research also integrated multiple software components to build a real-time gesture recognition system, applying the optimized model to the system. The real-time system achieved an accuracy of 96%, demonstrating the feasibility of applying ultrasonic technology for static gesture recognition.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-25{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-25 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-25{width:100% !important;order : 0;}.fusion-builder-column-25 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-25{width:100% !important;order : 0;}.fusion-builder-column-25 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-26 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">.fusion-accordian  #accordion-196-15 .panel-title a .fa-fusion-box{ color: #ffffff;}.fusion-accordian  #accordion-196-15 .panel-title a .fa-fusion-box:before{ font-size: 16px;

By knowing the distance and TOF, the propagation speed of sound in the medium can be estimated. Sound velocity in air can be influenced by environmental factors such as temperature, humidity, and atmospheric pressure, leading to inaccuracies in the average speed calculation. Current methods like pulse peak and signal modulation envelope approaches calculate sound speed using TOF, but they don&#8217;t account for temperature non-uniformity, which causes reflections and refractions due to differences in acoustic impedance, shifting waveforms and introducing TOF errors.<\/p>\n<p style=\"color: #ffffff;\">This research aims to improve spatial resolution for velocity estimation by addressing the challenge of calculating sound speed accurately without being affected by real-world environmental variations. In real scenarios, sound waves may experience attenuation, reflection, and echo interference, which hinder accurate sound velocity determination. Therefore, this study improves accuracy through algorithmic adjustments and an enhanced experimental setup.<\/p>\n<p style=\"color: #ffffff;\">The experimental setup includes 12 ultrasonic sensors arranged in a circular area, with each sensor spaced 30\u00b0 apart from the center. Each sensor can function as both a transmitter and receiver. Acoustic foam was placed around the sensors to reduce echo reflections. By measuring the time at which signals reach the receivers, the TOF for each path was calculated, allowing for the computation of sound velocity along those paths.<\/p>\n<p style=\"color: #ffffff;\">The study successfully identified methods for accurately determining sound velocity in gas with non-uniform temperature distribution. The algorithm minimized interference from reflections and refractions due to temperature differences, enabling the correct calculation of sound speed for each path. By analyzing the signal using noise intensity and applying a Schmitt-trigger-based decision criterion, the method effectively identified the main signal arrival time, improving the accuracy of sound velocity measurements, particularly in environments with uneven temperature distribution.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-26{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-26 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-26{width:100% !important;order : 0;}.fusion-builder-column-26 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-26{width:100% !important;order : 0;}.fusion-builder-column-26 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-27 fusion_builder_column_1_1 1_1 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><style type=\"text\/css\">@media only screen and (max-width:1000px) {.fusion-title.fusion-title-6{margin-top:15px!important;

In the monitoring system, the temperature information of the target area is often an indispensable part of the monitoring. The use of acoustic tomography can reconstruct a two-dimensional temperature distribution map of the target area without affecting the target area. The key challenge is how to improve the matching accuracy of the relative spatial distribution and the absolute temperature value.<\/span><\/p>\n<p><span style=\"color: #ffffff;\"> Using the ultrasonic temperature measurement method, the temperature of the medium in the target area can be calculated by the relationship between the transmission speed of the sound wave and the temperature of the medium. The ultrasonic array is used to generate dozens of ultrasonic transmission paths in the target area, and the temperature of the gas at each point on the two-dimensional plane is calculated based on the measured sound wave velocity of each path.<\/span><\/p>\n<p><span style=\"color: #ffffff;\">This study proposes an algorithm for reconstructing the temperature distribution based on multiple ultrasonic propagation paths, which is implemented in MATLAB. The algorithm primarily employs a spatial moving average technique and uses a hexagonal grid for the temperature distribution reconstruction. The study explores the impact of different grid shapes and sizes through several simulation tests. Three grid configurations (hexagonal, square, and polar) were analyzed for the accuracy of temperature distribution reconstruction. According to the results, the hexagonal grid most accurately tracks the peak temperature and movement of hotspots. In the ideal model, the average temperature error across all sound velocity paths is less than 1%, and when the hotspot moves outward from the center, the grid can detect the hotspot movement with a relative region diameter of 3%, with the maximum temperature error being less than 10%.<\/span><\/p>\n<p><a href=\"http:\/\/etds.lib.ncku.edu.tw\/etdservice\/view_metadata?etdun=U0026-1808202011180800&amp;class_search=yes&amp;from=DEPT&amp;fromid=D0026004002&amp;query_field1=&amp;query_word1=%E6%9E%97%E7%A6%8F%E6%9D%BE\" target=\"_blank\" rel=\"noopener\">\u6210\u5927\u5716\u66f8\u9928\u9023\u7d50(\u8acb\u9ede\u6211)<\/a><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-28{width:100% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-28 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 1.92%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 1.92%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-28{width:100% !important;order : 0;}.fusion-builder-column-28 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-28{width:100% !important;order : 0;}.fusion-builder-column-28 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><\/div><style type=\"text\/css\">.fusion-body .fusion-flex-container.fusion-builder-row-3{ padding-top : 0px;margin-top : 0px;padding-right : 0px;padding-bottom : 72px;margin-bottom : 0px;padding-left : 0px;}<\/style><\/div><div class=\"fusion-fullwidth fullwidth-box fusion-builder-row-4 fusion-flex-container nonhundred-percent-fullwidth non-hundred-percent-height-scrolling\" style=\"background-color: #333645;background-position: center center;background-repeat: no-repeat;border-width: 0px 0px 0px 0px;border-color:#eae9e9;border-style:solid;\" ><div class=\"fusion-builder-row fusion-row fusion-flex-align-items-flex-start\" style=\"max-width:1227.2px;margin-left: calc(-4% \/ 2 );margin-right: calc(-4% \/ 2 );\"><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-29 fusion_builder_column_1_4 1_4 fusion-flex-column fusion-no-small-visibility fusion-no-medium-visibility\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><\/div><style type=\"text\/css\">.fusion-body .fusion-builder-column-29{width:25% !important;margin-top : 15px;margin-bottom : 15px;}.fusion-builder-column-29 > .fusion-column-wrapper {padding-top : 0px !important;padding-right : 0px !important;margin-right : 7.68%;padding-bottom : 0px !important;padding-left : 0px !important;margin-left : 7.68%;}@media only screen and (max-width:1000px) {.fusion-body .fusion-builder-column-29{width:100% !important;order : 0;}.fusion-builder-column-29 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}@media only screen and (max-width:640px) {.fusion-body .fusion-builder-column-29{width:100% !important;order : 0;}.fusion-builder-column-29 > .fusion-column-wrapper {margin-right : 1.92%;margin-left : 1.92%;}}<\/style><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-30 fusion_builder_column_1_2 1_2 fusion-flex-column\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\" style=\"background-position:left top;background-repeat:no-repeat;-webkit-background-size:cover;-moz-background-size:cover;-o-background-size:cover;background-size:cover;padding: 0px 0px 0px 0px;\"><i class=\"fb-icon-element-2 fb-icon-element fontawesome-icon fa-book fas circle-yes fusion-animated icon-hover-animation-slide\" style=\"font-size:35.2px;line-height:68.4px;height:70.4px;width:70.4px;border-width:1px;border-radius:50% 50% 50% 50%;margin: 0px;\" data-animationType=\"fadeInLeft\" data-animationDuration=\"0.3\" data-animationOffset=\"top-into-view\"><\/i><style>i.fb-icon-element.fontawesome-icon.fb-icon-element-2{ color: #ffffff;
