Firstly, the characteristics of the operation process are analyzed, and the inverse kinematics of the serial manipulator is calculated by the characteristics of the operation. The solution is the precondition of controlling the motion of the manipulator. Secondly, the genetic algorithm is used to optimize the size of the manipulator by verifying the inverse kinematics solution, which makes the size of the manipulator more compact while the predetermined function is realized. Finally, considering the characteristics of the actual mechanical system, using Monte Carlo method to simulation and calculate the error of the end effector, it is verified that the manipulator meets the accuracy requirements of the actual operation.","PeriodicalId":232271,"journal":{"name":"2018 11th Biomedical Engineering International Conference (BMEiCON)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122647601","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}

Paralysis occurs commonly in this group of people. This is a disease that affects the nervous system, including muscular weakness or Amyo-trophic Lateral Sclerosis (ALS). Patients may not be able to walk or use their lower part of the body. Hence, physical activity is fundamental to human life, if the elders are not able to walk or use some of their body part, their quality of life will be reduce. For this reason, research and development of an equipment to assist physiotherapy rehabilitation or supports the movement of patients has been made. The focus has been drawn to standing and walking, which will result in a better functioning of the patient’s body. This lead to the creation of the prototype exoskeleton suit supporting the body movement. The wearable device consists of a movement mechanism, and a microcontroller-driven system. The development of the device is based on a normal human’s gait. In addition, the prototype has a mechanism for limiting the degree of movement of the joints in the waist and knee, with both mechanical and electrical security. Finally, this device can help the patient’s body stood up and assist the walk, which allowing them to take care of themselves and not rely on the family and society.","PeriodicalId":232271,"journal":{"name":"2018 11th Biomedical Engineering International Conference (BMEiCON)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123892205","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}

We performed validation of the constructed circuit and experiments for detecting action potentials of vagus nerve utilizing these tools. Consequently, the potential like the action potentials were measured.

For the image based classification, it is a complex task for CNN to deal with hundreds of MRI Image slices, each of almost identical nature in a single patient. So, classifying a number of patients as an AD, MCI or NC based on 3D MRI becomes vague technique using 2D CNN architecture. Hence, to address this issue, we have simplified the idea of classifying patients on basis of 3D MRI but acknowledging the 2D features generated from the CNN framework. We present our idea regarding how to obtain 2D features from MRI and transform it to be applicable to classify using machine learning algorithm. Our experiment shows the result of classifying 3 class subjects patients. We employed scratched trained CNN or pretrained Alexnet CNN as generic feature extractor of 2D image which dimensions were reduced using PCA+TSNE, and finally classifying using simple Machine learning algorithm like KNN, Navies Bayes Classifier. Although the result is not so impressive but it definitely shows that this can be better than scratch trained CNN softmax classification based on probability score. The generated feature can be well manipulated and refined for better accuracy, sensitivity, and specificity.","PeriodicalId":232271,"journal":{"name":"2018 11th Biomedical Engineering International Conference (BMEiCON)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131302303","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 algorithm efficiently extracts the inherent patterns present in the physiological signals, by exploiting the self-similarity of the signal. A finite set of aggregated processes are created from the raw EMG signal. Now, CENSUS transform values are calculated for each of these aggregated processes. Finally, the CENSUS transform values form the feature vector and this can further be utilized for characterization and classification of the EMG signals. For assessing the utility of the proposed feature extraction technique, extensive experiments are conducted on two publically available datasets using k-NN classifier. It is evident from the results that our method achieves higher classification accuracy than many of the state-of-the-art techniques.","PeriodicalId":232271,"journal":{"name":"2018 11th Biomedical Engineering International Conference (BMEiCON)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115602998","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}

Median filtering can efficiently remove the noise without blurring the edges. However, median filtering is computationally intensive and not suitable for real-time imaging. In this paper, median filtering on the intermediate ultrasound data using asymmetric median kernel sizes is proposed. To reduce the computational time, the median selection networks with compare-and-swap stages are applied instead of reducing the redundancy of the median calculation among the adjacent image pixels. Moreover, the modification of the compare-and-swap stages to suit for the GPU is also proposed. The computational times using CPU and GPU programs are compared and CNRs of the ultrasound images are also reported.","PeriodicalId":232271,"journal":{"name":"2018 11th Biomedical Engineering International Conference (BMEiCON)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114960797","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}
