First order plus dead time (FOPDT) structure and its vector parameters such as gain, time constant and dead time were estimated using linear regression technique. The optimum model parameters were achieved by minimizing the sum of squared error (SSE) between the measured temperature data and the generated data predicted from the model at every data point using Nelder-Mead (N-M) optimization algorithm.

By using the EEG brain wave controlled, the amputees can control the movement of the prosthetic arm by visualizing the movement of the arm. Besides the amputees, the paralyzed person can also use their thought to control the prosthetic arm. The EEG based brain wave controlled intelligent 3D printed prosthetic arm is designed to use the amputee's brain wave to control the movement of the prosthetic arm. The amputee needs to be trained in order to control every arm movement correctly. The EEG signal needs to be collected from the amputee on visualizing on 4 left forearm movements which are up, down, left and right. After that, signal pre-processing and Discrete Wavelet Transform (DWT) is performed on the EEG signal to obtain the alpha wave. Then, FFT is performed to the alpha wave to convert it to frequency-domain. The two-stage binary classifier that used Support Vector Machine (SVM) machine learning technique is created in the MATLAB to classify the alpha wave of the arm movement accurately for the user.","PeriodicalId":273439,"journal":{"name":"2020 IEEE 8th Conference on Systems, Process and Control (ICSPC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117097241","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 introduction of a deep learning approach in super resolution has drawn a lot of research interest in recent years due to its learning capability and noise immunity. The applications of deep learning super resolution can mainly be found in image recovery, medical imaging, and microscopy. In this paper, the deep learning super resolutions are explored in detail based on its models and architecture. They can be classified into three neural network (NN) models, i.e. Convolutional NN-based models, Recursive NN-based models, and Adversarial Network-based models. CNN-based models apply convolution operation to embed the latent feature and subsequently decode it with deconvolution operation to achieve a higher dimension. RNN-based models integrate the recursive depth model to enhance recursive learning with past memory. On the other hand, adversarial network-based models apply the generative manner to learn the probability of the input pattern to forecast the possible high dimension of output information. The details of each unsupervised model are discussed in this paper to highlight its advantages and limitations. The measurement metrics such as Peak Signal-to-Noise Ratio (PSNR), structural similarity (SSIM) and Mean opinion score (MOS) are highlighted for performance evaluation of each super resolution models. The significance of this study provide a compact review of the current development and trend in super resolution using various deep learning models.","PeriodicalId":273439,"journal":{"name":"2020 IEEE 8th Conference on Systems, Process and Control (ICSPC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125969396","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}

While the energy receiving terminals are harvesting energy, the information receiving terminals are receiving their desired signal-to-interference-plus-noise ratio (SINR) under the total power constraint at the transmitting terminal of the proposed SWIPT system. We use the Kronecker model to study the impact of MIMO antenna correlation and the Rician K-factor as the main parameter to set up the different fading conditions. We use semi-definite programming (SDP) to formulate the proposed SWIPT system. Our numerical results confirm that the performance of the proposed design improves in the absence of LOS component, i.e., with a zero K-factor or pure Rayleigh fading channel, and deteriorates as the LOS channel component grows. We show that the total harvested energy monotonically decreases as the Rician K-factor increases.","PeriodicalId":273439,"journal":{"name":"2020 IEEE 8th Conference on Systems, Process and Control (ICSPC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130171661","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}

Currently, there is a need for precision in motor control due to the rise in the rate at which things needed to be done as a result of the technology breakthrough. There are several techniques applied for motor control. The advantage of the conventional nonlinear techniques is the instant availability of models and also the existence of techniques for rigour evaluations. The investigated technique was subjected to different likely disturbances viz; the pulse signal, a decrease in the dynamic friction of the system by 50% and increase by 100%, and a decrease in the system moment of inertia by 50% and increase by 100%. The comparison was made with the PID and unity feedback versions of the system. Results show remarkable superiority of the sliding mode based technique over the other two for the system. It clearly showed that such changes considered could be compensated very well with the control system because despite the presence of perturbations its response was similar to without disturbance. The performance of the PID was by far better than with unity feedback. Hence, it indicates that the reaching law sliding mode control could lead to a remarkable improvement of such systems and similar in the future but after further investigations.","PeriodicalId":273439,"journal":{"name":"2020 IEEE 8th Conference on Systems, Process and Control (ICSPC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130797654","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}
