However, a paralyzed subject can still use the electrical activity of other intact muscles as a control command for the electric wheelchair. This system includes instrumentation and processing of electromyography (EMG) signal, and interpretation for controlling the wheelchair to move forward, backward, stop, turn left, and turn right. The EMG signal of the Flexor Carpi Radialis muscles was measured and amplified by a designed instrumentation amplifier. Then, the signal was filtered to eliminate noise and maintain the EMG frequency range of 20500 Hz. After filtering, the signal was processed more to produce a linear envelope and hold the maximum value of the envelope of the EMG signal. Interpretation of command from subject was determined by thresholing method to the envelope of the EMG signal. The results of wheelchair navigation with basic movements had an average success rate of 100% of 8 subjects. The test results past the determined track have an average success rate of 95.83% for 3 subjects. It is expected that in the future, the subjects can use the wheelchair with subject’s intention speed.","PeriodicalId":198107,"journal":{"name":"2019 International Biomedical Instrumentation and Technology Conference (IBITeC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128823385","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, these multiple streams configuration introduce dense interferences. This paper presents linear and non-linear techniques to cancel the interferences in very high data rate WLAN system. Those techniques were compared in term of performance and complexity. They are not only canceling the interference but also combining the multipath gain to obtain optimal signal to noise ratio. Zero Forcing (ZF) has the lowest complexity and performance. Minimum Mean Square Error (MMSE) considers the noise power to give better performance by low computation complexity. Maximum Likelihood Detection (MLD) gives the best performance by the cost of highest complexity, especially when deals with multiple streams. In the other side, other modern techniques, such as Sphere Detection and K-Best offer near performance to MLD by lower complexity. The comparison of those techniques was conducted under indoor channel model of IEEE802.11n Task Group.","PeriodicalId":198107,"journal":{"name":"2019 International Biomedical Instrumentation and Technology Conference (IBITeC)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116389757","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}

Using CT 3D image, it can be very helpful for a doctor in diagnosing medical information. In the development of 3D image reconstruction and computer technology, it is possible for the doctor to communicate with the patient through gadget media. This paper presents the determination of the threshold in single-slice Computerized Tomography (CT) for interactive 3D image reconstruction without user interface. The 3D image reconstruction method is the improved marching cube algorithm. The medical image object that consists of skull bone and sternum-pelvis in Digital Imaging and Communications in Medicine (DICOM) format is taken from single-slice CT. The resulting threshold for bone 3D image object is 200, except for the 3D image with quantity slice less than 10 can not be reconstructed. The difference in the surface volume and surface area between the 3D image reconstruction output from InVesalius software and project, for skull bone and sternum-pelvis is less than 0.5%. The justification of the visual shape match from three radiology doctors for skull bone and sternum-pelvis is approximately 99% match.

Mobile ECG devices are important medical innovation which has high potential to transform to homecare. We performed this review to learn on the current availability of portable ECG mobile technologies with respect to their scope, ease of use, data transmission capabilities, diagnostic accuracy and cloud based features. We conducted and Internet searches for \"handheld\" or \"patch\" or \"portable\" electrocardiography devices to enlist current available technologies. We also searched specific mobile ECG devices to obtain additional citations. We classified available devices as a \"single limb lead ECG recording devices\" and chest-lead \"ECG recording devices.\" Three electrodes ECG devices also defined as the conventional electrocardiography or Holter machine are excluded from this review. A total of 12 devices have been reviewed and identified as \"handheld\", \"patch\" and \"portable\" with four devices fall into each of the categories. Nine of the reviewed ECG devices have electrode attachment in the chest and the rest are handheld devices. All devices are very lightweight as they weight under 150g and easy to bring everywhere. We concluded that the number of available devices that can record and analyze ECG signals is on the rise. ECG devices with cloud based monitoring and analysis system involves various fields such as sensor technology, communication, software design, signal processing and data mining.","PeriodicalId":198107,"journal":{"name":"2019 International Biomedical Instrumentation and Technology Conference (IBITeC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134097229","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}

For children with special needs such as autism and down syndrome children, their hand muscles have lower muscle tone and weaker coordination. Hence, to improve their weak fine motor skills during their early childhood, an early intervention training system is needed. Previously, a training device with added features of light and sound tools is developed to prolong the attention span of these children when training. This paper aims to analysis EMG signals of these children during the fine motor training using the device. In addition, the attention span of these children during training with the device is compared to the conventional one, i.e. training fine motor with placing wooden block in a wooden peg. Four children with special needs, i.e. two in each autism and down syndrome categories, aged four to eight years old participated in the study. Results were compared with a normal child one. The EMG signal from flexor digitorum superficialis muscle was extracted using DataLOG Biometrics Ltd and stored in computer for further analysis. The normalised amplitude of EMG signal showed that normal child had the least fluctuation in muscle activity during training. All children showed decreased in normalised EMG amplitude at the end of training session compared to earlier one. It is also found that the attention span of children with special needs during fine motor training had increased almost double when using the developed device compared to conventional one.","PeriodicalId":198107,"journal":{"name":"2019 International Biomedical Instrumentation and Technology Conference (IBITeC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125387967","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 purpose of this study was to determine the effect of the fiber orientation on the bending strength of hybrid composites reinforced with E Glass and palm sugar fibers with polyester resin. The manufacture of hybrid composites in molds is done by combining palm sugar fibers with E Glass fibers. We used the hand lay-up method with pressing process (press mold) for making the composites. To remove the fiber content of palm fiber, the heating process was dried in an oven at 60° C for 30 minutes. The independent variables in this study are the fiber orientation 0°, 30°, 45°, 60° and 90° The dependent variables in this study are the flexural strength and fracture macro photographs. While the control variables in this study are sugar palm fiber, E Glass fiber, polyester resin and the hand lay-up method. The procedure and testing process for bending test specimens refer to ASTM D 790-02 standards. The results showed that the average flexural strength for fiber orientation of 0°, 30°, 45°, 60° and 90° are 168 MPa, 261 MPa, 231 MPa, 198 MPa and 93 MPa respectively. The highest flexural strength was obtained in hybrid composites with E Glass fiber fibers with 30° fiber orientation (261 MPa), while the lowest flexural strength was obtained at 90° fiber orientation (93 MPa). The results of a macro photo of a hybrid composites reinforced by palm sugar and E Glass fibers show that most of failure caused by fiber pull out and delamination.","PeriodicalId":198107,"journal":{"name":"2019 International Biomedical Instrumentation and Technology Conference (IBITeC)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122956544","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}

It causes no radiation and bad effect for the patient. The necessity of early detection of brain tumor leads the researchers to initiate this study. Early detection of a brain tumor can be observed through MRI image results. The brain MRI images are then processed by using 3 major steps, namely image processing, feature extraction and selection, and classification. The feature extraction and selection are one of the important steps that can determine the accuracy of brain MRI images classification in which its result will determine the disease. This paper examines 9 feature extraction and 3 feature selection methods for classification of brain MRI images. Furthermore, it explores the advantages and disadvantages of each method. Both of them are considered in the selection of the best method to be applied in different cases. The summary of each method is presented in a table as supportive evidence. This study shows that Local Binary Pattern combined with GLRL, ZM, PHOG, and GLCM is the best feature extraction method for BRATS dataset with a classification accuracy of 97.1%, while GLDM and GA are the best combinations of feature extraction and selection method for clinical datasets with a classification accuracy of 98%.","PeriodicalId":198107,"journal":{"name":"2019 International Biomedical Instrumentation and Technology Conference (IBITeC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116830531","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}

Without continuous monitoring by competent ophthalmologists, DR may lead to worse complications, including loss of vision. With the increasing number of DM population in Indonesia, there is also an increasing needs for more ophthalmologists to detect and manage DR patients. Therefore, ophthalmologists need an accessible learning platform to improve their ability to establish a fast and accurate DR diagnosis. We propose web-based training application called Optan, which accommodates repeated manual annotation of DR features on digital fundus images and provides a quantitative evaluation of its accuracy. Such functionalities will provide ophthalmologists in training with a more precise feedback on their diagnostic performance. Optan web interface is designed with a simple layout to make it easily understandable by users with a choice of various shapes to annotate different DR features. In addition, it is equipped with a function to calculate the Jaccard index similarity of annotations made by a resident ophthalmologist compared to a reference specialist. We evaluated Optan user satisfaction and quantitative evaluation feature on respondents including ophthalmologists and academics working with fundus images. Optan scores an average of 7.3 from the scale of 9 in the standard QUIS user satisfaction survey. The highest annotation consistency of six ophthalmologists is achieved on optic disk circular annotation as opposed to microaneurysm point and blood vessel line annotations.","PeriodicalId":198107,"journal":{"name":"2019 International Biomedical Instrumentation and Technology Conference (IBITeC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130230059","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}
