In this model, different types of possible faults in the WTBM such as in sensor, actuator, and system are modelled. Support Vector Machines (SVM) and Artificial Neural Network (ANN) are used for the fault classification in a comparative study for fault in pitch position due to an error in sensor measurement; generator torque offset due to actuator fault and changed dynamics effect on angular speed. The SVM classifies more accurately than existing results and ANN for the faults under study.","PeriodicalId":192369,"journal":{"name":"2019 Global Conference for Advancement in Technology (GCAT)","volume":"35 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":"114797586","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 thesis is to predict the LIBOR in USD with two algorithms: the pure Genetic Algorithm (\"GA\") and the Genetic Algorithm integrated with Recurrent Neural Network (\"GA + RNN\"). The pro and cons of these two algorithms will be compared, with fitness values and Mean Squared Error (\"MSE\"). 50 test cases will be created and tested randomly to verify the performance of the predictions. In the algorithm of RNN+GA, the target variance between predication and real value is no more than 0.015.","PeriodicalId":192369,"journal":{"name":"2019 Global Conference for Advancement in Technology (GCAT)","volume":"21 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":"124483759","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}

Therefore, the lower capability of sensor devices need to operate wisely with careful technical considerations to maximize their capabilities. This paper proposes a new technique to improve reliability and cybersecurity by balanced use of sensor energy while maintaining the quality of communication. The simulation result shows that the strategy proposed is effective. A hacking strategy has also been detailed so that the security experts can consider those while designing a security suite for IoT-enabled infrastructures.","PeriodicalId":192369,"journal":{"name":"2019 Global Conference for Advancement in Technology (GCAT)","volume":"81 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":"126224214","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 moving vehicles are detected and tracked using Motion Vector Interpolation technique. The speed is calculated and displayed for each vehicle in the input video which is for every 0.6 seconds.

Pre-processing is performed on retinal images by extraction of green channel images being subject to adaptive histogram equalization, Laplacian filtering followed by morphological bridging operation.

In this paper, the analysis and implementation of the method in which the low frequency ambient vibrations are used to generate low power using cantilever based piezoelectric vibration sensor is carried out. Here, the simulation of the sensor structure is done using COMSOL Multiphysics to analyze the stress, strain, displacement, natural frequency and modal frequencies of the designed cantilever. The effect of dimension of the structure (like length, width and thickness), the piezoelectric material, and the volume of the tip mass and clamp positions on natural frequency and voltage is analyzed. The optimized simulated values are compared with the theoretical values and the actual sensor’s (PPA 1001) values. The results are in close approximation. The output signal is rectified and conditioned so that it can be used to power electronic gadgets. LTC 3588 is used for signal conditioning. In this work, a massager having frequency range in 70-80Hz is used as vibration source. With the optimized values of sensor position, clamping and tip mass, the output voltage available is 16V (p-p). This is conditioned further to get a constant output voltage of 3.3 V.","PeriodicalId":192369,"journal":{"name":"2019 Global Conference for Advancement in Technology (GCAT)","volume":"42 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":"134427318","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}
