To restore the normality of bite condition, the upper molar is often moved distally using an orthodontic device. The objective of this study was to predict and compare the outcomes of two different orthodontic devices both equipped with miniscrews. The first device, called a buccal mini-implant, has miniscrews placed on the alveolar bone on the buccal surface. The second device, called an indirect palatal miniscrew anchorage and distalization appliance or iPANDA, has miniscrews inserted along the midline of the palatal bone. For comparison purpose, a three-dimensional (3D) model of both devices was virtually attached to a 3D model of the upper teeth with maxillary bone and periodontal ligament. A force of 200g was applied through the devices to simulate a recommended distalization force. Teeth displacement, stress in both miniscrews and surrounding bone, and micromotion at miniscrew-bone interface were measured using finite element method. The findings show that the iPANDA device led to a higher molar distalization and higher micronmotion compared to the buccal mini-implant device. Stress obtained from the iPANDA device was also found to be higher, however, it was relatively too small to damage both the miniscrew and surrounding bone.","PeriodicalId":293245,"journal":{"name":"Proceedings of the 2019 9th International Conference on Biomedical Engineering and Technology - ICBET' 19","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123735683","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}

This paper proposes a binary classification system through which EEG signals are analyzed to distinguish between ictal and normal signals. For this purpose discrete wavelet transform (DWT), along with gradient boosting is used for classification. Two level, Daubechies order 4 wavelet are used to decompose the signal into three sub-bands after which Hjorth mobility and Hjorth complexity are calculated from these sub-bands resulting in a 6-dimensional feature vector. We use two benchmark datasets in our experimentation i.e., the Bonn's dataset and CHB-MIT dataset. We establish our classifier using training samples from the Bonn's dataset. Classification accuracy of 99.4% is achieved when tested on same dataset using different samples. To validate the effectiveness and better generalization of our system, we cross-test on CHB-MIT dataset which yielded accuracy of 96.8%. Achieved performance surpasses previous state of the art technologies, giving better classification results than other well-known techniques used for seizure classification. Considering low feature dimension and hence decreasing complexity, coupled with the high performance on both datasets prove the given method to be favourable for distinguishing between epileptic and non-epileptic EEG signals.","PeriodicalId":293245,"journal":{"name":"Proceedings of the 2019 9th International Conference on Biomedical Engineering and Technology - ICBET' 19","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115973840","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}

This paper examines and measures the concentration of pentane, ammonia and other volatile organic compounds (VOCs) in determining schizophrenia using breath analysis. The preliminary performance of the electronic nose has been demonstrated on 10 breath samples from a subject that has schizophrenia than in healthy individual subject which has found out that the e-nose can discriminate the patterns of VOCs from these two groups. Confusion matrix was used to show the accuracy of the system in detecting schizophrenia.

Tetrapolar and eight-polar electrode system are conventionally used to measure transimpedance computed from skin voltage information. Each system has different sensitivity of voltage measurement to the presence of fat in the different part of the body. Consequently, each system may have limitations to detect fat residing in different regions. In this studies, these limitations were investigated by simulation. Three current schemes and three measurement positions were simulated to detect the increase of fat in the whole body. The result showed that the tetrapolar system was able to detect fat only the half limb of the body. On the other hand, the eight-polar system can detect fat in the whole body. However, fat residing in the arms, the hip, the thighs, and the bottom may influence the accuracy of the fat mass estimation, because the bioimpedance of these regions is used as both the bioimpedance of the trunk and that of the legs or the arms. It is also found that the breast which is mostly fat had less influence in the estimation. This means the estimation for the fat mass of women may be not accurate and may be less in correlation to the breast size as well.","PeriodicalId":293245,"journal":{"name":"Proceedings of the 2019 9th International Conference on Biomedical Engineering and Technology - ICBET' 19","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129266995","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}

This study was conducted to determine the correlation between the activity frequency (AF) of array PPG image and the changes in skin surface temperature (SST) by environment temperature control. The study participants were 13 company employees aged between 27 and 48 years (mean age: 35.6 years) who were treated with an IR heater to increase the skin temperature for approximately 15 min. Measurements of finger array PPG and finger SST were obtained before infrared heating as baseline, and the intervention of 15-min infrared heating was continued in the left hand as the experiment group. The right hand was not subjected to heating, which served as the control group. The results showed that the local fingertip SST increase affected the local AF of the array PPG image, which could be related to the biphasic skin blood flow response. The array PPG image could be used for monitoring the activity control of microcirculation or endothelial function.","PeriodicalId":293245,"journal":{"name":"Proceedings of the 2019 9th International Conference on Biomedical Engineering and Technology - ICBET' 19","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121842079","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}

The correlation indices were computed based on spectral features employing the relative powers (RP) of delta (ΔRP), theta (&thetas;RP), alpha (αRP), beta (βRP), and gamma (γRP). The next step was calculation of Pearson's correlation between the of the neutral state and the of the six fundamental emotional states (i.e. anger, anxiety, disgust, happiness, sadness and surprise) of every EEG channel for different brain areas (i.e. frontal, temporal, parietal and occipital scalp).

The objective of this study was to evaluate spinal loads for three different lifting techniques; stoop, squat, and kneeling, at several levels of the lumbar spine. The present study was conducted via musculoskeletal modeling using commercial software (AnyBody Technology). The results indicate that there was no significant difference in compressive and resultant force among the three liftings. However, the difference in shear force between stoop and kneeling lifting was found to be significant. Increasing level of the lumbar spine significantly led to the decrease of shear force.
