It was first proposed as a method for self-assembly but was later redefined as a technology that allows printed objects to shape-shift while being exposed to the environment. This paper proposes a novel method to fabricate a 4D-printed microgripper utilizing the shape memory effect of polylactic acid (PLA), which is a shape memory polymer. Finite element analysis is carried out to investigate the microgripper’s movement, which operates based on the actuation of beam-like structure. The self-bending capability due to the release of internal pre-strain of printed materials is used to simulate the actuation of the structure. The microgripper consists of two active beams that can be stimulated at 85 °C, while the rest of the microgripper is passive. Fused deposition modeling is used to fabricate the active and passive parts of a microgripper, where different printing parameters were used for each part. The microgripper fingers achieved an actuation distance of 3 mm for the actuators’ deformation distance of 3.925 mm each, giving a ratio of 0.76 in the two distances. The results show that the developed microgripper has a high potential to be miniaturized and implemented in various biomedical and micromanipulations applications.","PeriodicalId":6762,"journal":{"name":"2021 IEEE 19th Student Conference on Research and Development (SCOReD)","volume":"26 1","pages":"207-211"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79147549","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}

Transmission lines are one of the most used technical systems for transporting large amounts of electricity from one part of a country to the farthest point in the opposite direction. The transmission lines traverse many terrain types and geographic regions, which makes them more sensitive to various types of atmospheric disasters and causes frequent line faults and power outages. Therefore, power system reliability and power loss are important, since if these losses are higher than the industry norm, the amount of power accessible to customers will be reduced. Power from a distributed generator (DG) system is incorporated into a power system in this study to improve the power system reliability, average energy not supplied (AENS), and reduce transmission line losses. The results of an optimal DG installation are gained from the penetration of distributed generation in an IEEE 14-bus system by using the Evolutionary Programming (EP) optimization technique. The results prove that with the use of EP optimization, power system reliability can be improved post optimization.","PeriodicalId":6762,"journal":{"name":"2021 IEEE 19th Student Conference on Research and Development (SCOReD)","volume":"16 1","pages":"174-179"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87796794","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, stroke patients use available motor strategies to reach the target position to compensate for their upper limb weakness. This can lead to inaccurate assessment data for the predictive analysis. The primary goal of this study is to examine the effect of shoulder movement in upper limb assessment for predicting the Motor Assessment Scale (MAS) score using Partial Least Squares (PLS), Artificial Neural Network (ANN), and hybrid (i.e. PLS-ANN) predictive models. However, the feature selection method on the model's input predictor influences the predictive model's performance. To attain the greatest prediction performance, an appropriate feature selection method should be investigated. The results reveal that PLS-ANN with all kinematic variables (KVs) as the input predictors has a better prediction accuracy after the implementation of shoulder movement compared to other predictive models. Furthermore, the results proving that by considering shoulder movement to generate the KVs based on the actual distance of reaching movement may enhance the prediction accuracy in predicting MAS score of stroke patients.","PeriodicalId":6762,"journal":{"name":"2021 IEEE 19th Student Conference on Research and Development (SCOReD)","volume":"95 1","pages":"239-244"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82862226","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}

As a result, the visible light communication-based indoor navigation system becomes feasible. A few factors could affect the accuracy of the Indoor Navigation System, such as multipath effects, environmental interference, etc. This paper presents an investigation of the factors that could lead to inaccuracy during the navigation process by obtaining the respective signal-to-noise ratio (SNR). A simulation framework for a LED-based Indoor Navigation System is developed. A unique frequency modulation (F-ID) modulation technique was used in the transmitter to assign a unique frequency identification for each LED. A photodiode was used to convert the received optical signal into an electrical signal. The Received Signal Strength (RSS) method and trilateration algorithm are adopted to evaluate the receiver device’s location. The LED-based Indoor Navigation System framework is evaluated using positioning estimation errors and SNR.","PeriodicalId":6762,"journal":{"name":"2021 IEEE 19th Student Conference on Research and Development (SCOReD)","volume":"os-17 1","pages":"24-29"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87197947","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 nature of sarcasm is to express opinions in a way that carries the opposite sentiment as a way to insult or make fun of the situation. Because of its nature, it poses a very difficult challenge in text classification task as they will be classified according to words used and not the meaning implied. Therefore, the accuracy of classification will be affected significantly. Sarcasm is also a problem for the task of sentiment analysis and emotion detection, as they reflect opposite sentiments of the author. So, sarcasm detection is needed to find the sarcasm text and revert the sentiment of the text. In the recent works seen in sarcasm detection, machine learning methods and deep learning methods are more commonly used to perform the task. Although deep learners are efficient learners, machine learner are still widely used and can perform as well as deep learners with proper training. This work seek to compare the different ensemble settings to evaluate the performance of ensembles against simple learners. The results show that ensembles can improve the performance of simple learners and even deep learners.","PeriodicalId":6762,"journal":{"name":"2021 IEEE 19th Student Conference on Research and Development (SCOReD)","volume":"44 1","pages":"284-289"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73866407","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}
