Running shoe cushioning characteristic is postulated can enhance running performance and reduce the potential risk of running related injuries. The soft and hard cushioning footwear will affect the running gait especially after shoe aging. Several studies have investigated the link between running shoe cushioning and running biomechanics. However, there were generally inconsistent finding being reported. So, the purpose of this study is to perform a biomechanical analysis if running shoe cushioning properties can have positive effect on distance running. 10 amateur runners participated in this study and completed 80 km running distance within timeline. They were divided into two groups who run with soft cushioning and hard cushioning shoes respectively. The lower extremities joint flexion range of motion and vertical ground reaction force were accessed at baseline, after 40 km and 80 km of running. The result showed that hardness of cushioning was increased if the running distance increased. Greater range of motion was observed for both hard and soft cushioning condition when the running distance was accumulated to 80 km. Hard cushioning running had significantly higher range of motion and ground reaction force if compared to soft cushioning running. In conclusion soft cushioning running produces less impact load may result in better protection on running injury.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115462737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EEG signals have been one of the most accurate and reliable markers of driver fatigue. Despite this, extracting valuable features from cluttered EEG signals still difficult to detect driving fatigue. This study aims to create a novel real-time methodology for detecting driving fatigue based on EEG signals. The study utilizes the Discrete Wavelet Transform (DWT) to obtain different EEG bands and compute power spectrum density (PSD) and other statistical features over each DWT band for the online detection of mental fatigue. Deep learning, particularly convolutional neural networks (CNN), has demonstrated impressive results in recent years as a method to extract features from EEG signals among various analysis techniques successfully. Although automatic feature extraction and accurate classification are advantages of deep learning, designing the network structure can be challenging and requires a vast amount of prior knowledge. Therefore, we used these features as input to CNN instead of using raw EEG data directly. Classification results of multiple machine learning models such as Support Vector Machine (SVM), k-nearest neighbor (kNN), Linear discriminant analysis (LDA), Decision Tree (DT), and Naive Bayes (NB) classifiers are also explored to obtain an optimum solution of the driver's fatigue evaluation. Two driving fatigue EEG datasets were used as testbeds to denote the effectiveness of five conventional classifiers and CNN. The proposed method reached more than 99% classification accuracy using a kNN and CNN in both datasets. The outcomes confirmed the efficacy of the suggested approach.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121923076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the objective analysis method is less feasible in hospital environments for treatment purposes due to limited coverage of sources. Thus, this study aims to develop a classification algorithm that can effectively classify subjects with relatively simplified temporal spatial gait data. This study employed several datasets acquired from PhysioNet containing subjects’ gait data of three classes. The training dataset contains a total of 48,318 instances of three target classes (young healthy adults, old healthy adults, and Parkinson’s disease patients). Two classification algorithms were developed: Support Vector Machine (SVM) classification algorithm and Artificial Neural Network (ANN). Preprocessing was performed to the original dataset which includes data cleaning, data normalization and new features generation. Next, fine-tuning on the manipulating hyperparameters was performed, and 10-fold cross validation was applied. The optimum configuration of SVM model can generate an accuracy of 93.01% and F1 score of 0.92 with 43 minutes of computational time. On the contrary, the optimum configuration ANN classifier generates an accuracy of 90.56% and F1 score of 0.89 with 112 minutes computational time. Conclusion: In conclusion, comparing both of the proposed classification algorithms, the SVM classifier is more effectively than ANN classifier as overall for the gait dataset used in this study. In addition, after compared with other state-of-the-arts of gait classification algorithms, our proposed classification algorithm produced comparable results with other state-of-arts using a smaller dataset with fewer training features. Clinical Relevance– This establishes the potential of apply machine learning algorithm on basic gait data obtained from the objective gait analysis method in classification of healthy adults, older adults, and Parkinson’s patient.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130449114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indeed, 3D visualization of the fetus prominent skull could help the obstetricians in decision-making to overcome dystocia, a delivery complication which results in labour obstruction. The full reconstruction pipeline is based on the recording of a small set of tracked 2D ultrasound images around the transthalamic brain plane. The use of 2D ultrasound images tracked in 3D space would allow to superimpose the fetal head model to other reconstructed organs. The fetal head is large at late pregnancy stages which causes occlusions in the ultrasound images. Moreover, fetal motion may affect the consistency of ultrasound images, in particular if many frames are needed. Therefore, we propose to extrapolate the full fetal head surface from 10 focused frames only. The reconstruction performance was evaluated in simulation based on a MRI dataset of 7 patients at 34-36 weeks of pregnancy; our best method achieves 1.6 mm of average reconstruction error.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132980735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a dielectric barrier discharge plasma sheet generator was designed to replace the traditional plasma jet. The sheet generator is able to scan large surfaces as compared to a plasma jet. High purity helium was used as the working gas (~30-60 slpm), and the plasma was generated using an AC power supply (5-10kv, 10-30 kHz). The input plasma power was measured to be around a few Watts (~10-25W) depending on the operating conditions of the torch. An automated 2D traversing system was designed and used to scan the plasma sheet and measure plasma gas temperatures along the plasma sheet. Experimental results show that the temperature varies across the plasma sheet for up to 16 percent, and temperatures are more uniform near the exit of the plasma torch. The effectiveness of the plasma torch was determined by running it over agar plates in which E. coli K-12 bacteria was grown. An apparent reduction in the bacterial colonies (up to 44%) was observed as the plasma sheet was scanned along the petri dish for five minutes. The plasma sheet traverses a larger area, which is beneficial because it reduces the time taken by the plasma jet to cover the same area on the petri dish.","PeriodicalId":146681,"journal":{"name":"2022 IEEE-EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128707165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These devices are generally bulky, with complex user interfaces and no integration of mobile applications, as well as auto fever-type classification algorithms for potential disease screening. As a result, this paper presents a 2-in-1 home-based vital sign monitor based on an Arduino Nano microcontroller, a DS18B20 temperature sensor to measure body temperature from the fingertip, and an MPX5050DP pressure sensor to acquire blood pressure based on the oscillometric method.

Google Firebase Authentication is also deployed for user authentication. The results show that the system provides an accurate vital sign measurement of 98.75% and 99.94% for blood pressure and body temperature, respectively.

Six groups were set up with a combination of the three exercise support apps and with and without the CO app. Thirty employees in each group continuously used their assigned apps for 10 weeks. In the group using the WA app, frustration significantly decreased (-22%). In the group using the IE app, total mental stress (-14%), frustration (-19%), fatigue (-21%), anxiety (-23%), and depression (-22%) decreased. In the group using the WA and CO apps together, fatigue decreased (-20%). In the group using the FW and CO apps, total mental stress (15%), fatigue (-23%), and anxiety (-34%) decreased. These results indicate that negative emotions (frustration, fatigue, anxiety, and depression) can be alleviated by our apps, but positive emotions (liveliness) and physical sensations (physical complaints) are not affected. A two-way analysis of variance (ANOVA) was applied to these mental stress reduction effects. There were no main effects for all indicators, but simple main effects were calculated for those that had interactions: fatigue under the WA app condition $(mathrm{p}lt 0.05)$ and anxiety under the FW app condition $(mathrm{p}lt 0.01)$ decreased more when the CO app was used. However, frustration decreased more under the IE app condition when the CO app was not used $(mathrm{p}lt 0.05)$.

An efficient Info-WGANGP approach is adopted for data augmentation by generating new HEp-2 cell images and enlarging the size of the training set. Meanwhile, an ensemble deep learning strategy is implemented to build a backbone network obtaining a potent combination of the deep features using three well-known deep convolutional networks, i.e., DCRNet, DSRNet, and HEpNet. The evaluation experiments on the publicly available I3A dataset demonstrate promising classification results in terms of average classification accuracy (ACA) with 98.82% and mean class accuracy (MCA) with 98.91% outperforming the latest deep learning approaches.
