Research ArticleOpen accessIn the author namesA Novel Approach of Satellite Image Enhancement Using DWT Based on 2-Type Fuzzy LogicSurjeet Singh Patel, Vivek Kumar Tamta, Abhilekh Bartwal et al.This study proposes a new approach to enhance the dark and low-contrast satellite images captured under poor illumination. Images are converted from RGB to HSV color space in order to separate the Hue (H), Saturation (S), and luminance (V) components. Enhancement is achieved in saturation and luminance components using Discrete Wavelet Transform (DWT) and 2-type fuzzy logic. DWT breaks the … …Journal of Computer Science, Vol. 19, Issue 9 · 15 Aug 2023 · 5,182 accessesView PDF Cite

Research ArticleOpen accessIn the author namesCardiovascular Diseases Identification Using Wavelet Optimization and Modify Cuckoo Search AlgorithmBanit Negi, Abhilekh Bartwal, Agya Ram Verma et al.The problem the author aims to solve is the extraction of discriminatory features in ECG (Electrocardiogram) signals for classification purposes. The scope of the work is to propose a new method for building wavelets that best reflect the discriminatory capacity of ECG signals. The approach involves optimizing the wavelets specifically for the classification function under consideration. To address the problem, … …Journal of Computer Science, Vol. 19, Issue 8 · 3 Aug 2023 · 5,403 accessesView PDF Cite

Research ArticleOpen accessIn the author namesTHE PROBABLE MEDICINAL USAGE OF CASSIA TORA: AN OVERVIEWSantosh Kumar Shukla, Anand Kumar, Marcelle Terrence et al.Cassia tora (C. tora) is a small shrub budding as weed in Asian and African countries. It is a known edible leafy vegetable taken up by Asians. From time immemorial, different parts of C. tora have found application in Indian and Chinese medicine. Its varying useful medicinal effects are well documented in many publications. In this review we have compiled … …OnLine Journal of Biological Sciences, Vol. 13, Issue 1 · 17 Jan 2013 · 8,046 accessesView PDF Cite

Research ArticleOpen accessIn the author namesMicrornas are Not That Small to IgnoreSanjeev Kumar Srivastava, Sonal Somvanshi, Vivek Pratap SinghMicroRNAs (miRNAs) are small, noncoding RNA molecule that negatively regulates gene expression by causing either degradation or translational inhibition of their target mRNAs. These miRNAs are key regulators of various biological processes such as differentiation, maturation and maintenance of immune homeostasis. Furthermore, deregulated expression of miRNA has now been shown to regulate several disease processes by regulating tumorigenesis, angiogenesis, apoptosis … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 8,456 accessesView PDF Cite

Research ArticleOpen accessIn the author namesFocal Adhesion Kinase: An Old Protein with New RolesAtul Kumar Pandey, Sonal Somvanshi, Vivek Pratap SinghFocal adhesion kinase, FAK is a tyrosine kinase which is prominently localized to focal adhesions and therefore its name, is an indispensable protein in integrin signaling. Since the discovery of FAK, this tyrosine kinase had been shown to regulate a variety of cell behavior like cell migration, proliferation, apoptosis and metastasis which makes this molecule at a centre stage of … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 13 Mar 2012 · 8,439 accessesView PDF Cite

Research ArticleOpen accessIn the author namesImplementation of Line Stability Index for Contingency Analysis and Screening in Power SystemsC. Subramani, Subhransu Sekhar Dash, Vivek Kumar, Harish KiranProblem statement: Estimating the margin in the loadability of the power system is essential in the real time voltage stability assessment. Voltage stability is currently one of the most important research areas in the field of electrical power system. In power system operation unpredictable events is termed as contingency and may be caused by line outage in the system which … …Journal of Computer Science, Vol. 8, Issue 4 · 11 Feb 2012 · 7,132 accessesView PDF Cite
