MPPT is an electronic device that enables the system to draw the maximum available power, what PV panel is capable of generating under changing temperature and irradiance by using several types of algorithms and methods. Conventionally perturb and observe (P&O) method and incremental conductance method have been used for designing MPPT, as they provide a simple and cost effective way of tracking. But either they have drawback of slow operation or low tracking efficiency. However, Artificial Neural Networks (ANN) can be deployed for this purpose, as they can track the optimal operating point (MPP) quickly and accurately based on training data sets. This paper presents three ANN based MPPT methods: Direct ANN, Cascaded ANN and the proposed Hybrid method. The ANN’s are trained using training data set of maximum power point voltages (VMPP) from a user defined PV array over different environmental conditions (temperature and irradiance). In this research work, a user defined PV array and three MPPT models are simulated in SIMULINK.","PeriodicalId":320507,"journal":{"name":"2019 3rd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125299396","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}

Cervical cancer has been considered as a frequent type of cancer among women. The attributes that are involved in enhancing the likelihood of cervical cancer are considered as the risk factors of this cancer. If it is possible to point out the risk factors of cervical cancer, the reason behind this disease can be understood easily. Thus, through proper treatment, mortality rate can be minimized and the quality of care can be increased. The aim of this study is to point out the risk factors of cervical cancer and find a model that provides good performance in predicting cervical cancer. In this research, Recursive Feature Elimination (RFE) and an ensemble approach based on Random Forests classifier have been used to identify the factors having much significance in predicting cervical cancer. Support Vector Machine (SVM), Multilayer Perceptron, and Logistic Regression have been used to evaluate the performance. SVM with an ensemble approach based on Random Forests classifier has outperformed than others with the accuracy of 91.04%, specificity of 91.94% , and AUC score of 0.89 for an independent test set.","PeriodicalId":320507,"journal":{"name":"2019 3rd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124586684","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}

DNA methylation is one of such type of genomic change. When one or more methyl groups are added to the DNA molecule, it is termed as DNA methylation. It is very difficult and challenging to deal with DNA methylation because of having high dimentionality and noisiness of methylation dataset. In this research work, we have proposed a machine learning based computational model for predicting DNA methylation. Our model is highly involved with bioinformatics and genomic information to extract genomic features. All previous works regarding the prediction of DNA methylation were only based on the statistical tools. Our model has two phases including the feature extraction and selection phase and the classification phase. In feature extraction phase we have used k-mer bioinformatics algorithm to extract the most appropriate features. Then using some statistical tools, we have selected the most discriminating features. Finally, we have chosen SVM, a supervised machine learning algorithm to predict the DNA methylation status. Our model has produced a classification accuracy of 98.65%.","PeriodicalId":320507,"journal":{"name":"2019 3rd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121524624","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}

Hybrid precoding architectures are broadly analyzed in mmWave massive multiple input multiple output (MIMO) systems because of its ability to mitigate the RF chains significantly. In most of the hybrid precoding networks, the analog processing part is implemented by phase shifters (PS) which consumes high energy, or by low-complexity switches (SW) which reduces the power consumption to a great extent; where both architectures consider simply mmWave channel. In this research, energy efficiency (EE) of a low-complexity SW-based hybrid precoding utilizing the antenna selection (AS) algorithm is analyzed for a mmWave m-MIMO system in various channels (e.g., Rayleigh, Rician and Nakagami-m fading channel). Simulation results indicate that the SW-based network enjoys a much higher EE than other schemes in each of the channels considered and therefore is an aspiring candidate for upcoming green communication approach.","PeriodicalId":320507,"journal":{"name":"2019 3rd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128794710","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 first compares the proposed robust LCMV method with the conventional LCMV method in the presence of direction of arrival mismatch. Then its performance is compared with the LCMV using existed fixed diagonal loading method. The proposed robust method raises the output power by 1.88 dB and output SINR by 0.58 dB at 3 degree disparity angle compared to the LCMV with fixed diagonal loading technique.

However, generating possible future audio block from the previous audio block is still a new idea that can help to reduce both audio noise and partially missing an audio segment. In this paper, a generative adversarial network (GAN) along with a pipeline is proposed for the prediction of possible audio after an input audio sequence. The proposed model uses short-time Fourier transformation of audio to make it an image. The image is then fed to a conditional GAN to predict the output image. After that, Inverse short-time Fourier transform is then applied to that predicted image, generating the predicted audio sequence. For a small audio sequence prediction, the proposed methodology is quite fast, robust and has achieved a loss of 0.43. So it is may work well if deployed on a voice call and broadcasting applications.","PeriodicalId":320507,"journal":{"name":"2019 3rd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)","volume":"42 17","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113974450","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}
