A new and efficient converter for the moduli set using multipliers, carry saves and modular adders is proposed based on a cyclic jump approach. A theoretical hardware implementation and comparison with a state-of- the- art scheme showed that the proposed scheme performed better. The 4- moduli set selected provides a larger dynamic range which is needed for Digital Signal Processing (DSP) applications [7].</p> 2021-05-05T00:00:00+0530 Copyright (c) 2021 https://ojs.trp.org.in/index.php/ajcst/article/view/2698 Analysis on Machine Learning Techniques for Stress Detection among Employees 2021-06-29T12:26:21+0530 B.

Radhika radhika.ad@vvce.ac.in <p>Mental stress is a common and major issue nowadays especially among working professional, because employees have family commitments with their over workload, target, achievements, etc. Stress tends various health issues like heart attack, stroke, depression, and suicide. Mental stress is not only in employees even normal people also face this problem but the employees has so many stress management techniques to manage the stress like yoga, meditation etc., but still employees suffer from the stress. Stress calculated by the Traditional stress detection method has two types of physiological parameters one is questionnaire format and another one is physiological signals based on Heart rate variability, galvanic skin response, BP, and electrocardiography, etc., Machine learning techniques are applied to analyze and anticipate stress in employees. In this paper, we mainly focus on different machine learning techniques and physiological parameters for stress detection.</p> 2021-05-05T00:00:00+0530 Copyright (c) 2021 https://ojs.trp.org.in/index.php/ajcst/article/view/2699 Automated Detection of Multiple Sclerosis Lesions in Normal Appearing White Matter from Brain MRI: A Survey 2021-06-29T12:37:25+0530 Manoj V. Khatokar manojvkhatokar@gmail.com M. Hemanth Kumar manojvkhatokar@gmail.com K. Chandrahas manojvkhatokar@gmail.com M. D. Swetha manojvkhatokar@gmail.com Preeti Satish manojvkhatokar@gmail.com <p>Multiple Sclerosis is an inoperable disease of the Central Nervous System (CNS) that irritates the myelin sheath by forming lesions. This affects all organs of the CNS; the vital of them is the brain. This disease can be detected by diagnosis like Magnetic Resonance Imaging (MRI). It is a non-invasive diagnostic test that provides detailed images of the soft tissues of the body. Out of the different variations of MRI, MS lesions are predominantly visible in the DTI (Diffusion Tensor Imaging) variant of MRI. DTI gives enhanced visualization of normal-appearing white matter tracts of the organs, hence providing a better image of the MS lesion. In this paper, the latest methodologies regarding the identification of the MS lesions in MRI scans like T2 FLAIR or DTI, using automated techniques like deep learning, computer vision, neural network and many more are surveyed. Furthermore, this paper consists of a proposed model which would focus on correlating the lesions found in DTI scan with the basic MRI scan like T2. It would identify the MS lesion in DTI scan and eventually highlight that lesion position in the T2 image scan. This would help radiologist in a way to effectively handle multiple MRI scans.</p> 2021-05-05T00:00:00+0530 Copyright (c) 2021 https://ojs.trp.org.in/index.php/ajcst/article/view/2700 Ad Hoc Vehicle Networks: Recapitulation and Challenges 2021-06-29T14:29:15+0530 S.
