Research ArticleOpen accessIn the keywordsDot Detection of Braille Images Using A Mixture of Beta DistributionsAmany Al-Saleh, Ali El-Zaart, Abdul Malik Al-SalmanProblem statement: Braille is a tactile format of written communication for people with low vision and blindness worldwide. Optical Braille Recognition (OBR) offers many benefits to Braille users and people who work with them. Approach: This study presents an algorithm for detecting dots composing braille characters in an image of embossed braille material obtained by an optical scanner. We assumed … …Journal of Computer Science, Vol. 7, Issue 11 · 6 Sep 2011 · 7,436 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign and Analysis of SRAM Cell for Smart ApplicationPushkar Praveen, Rakesh Kumar SinghIn today's circuittechnology, power consumption and savings are key concerns. The driving reasonsbehind these innovations are portable devices that require high throughput andlow power dissipation, such as computers, phones, and Personal DigitalAssistants (PDAs). In portable devices, reducing or decreasing IC dissipatedpower through design optimization is a big problem, and restricted batterylifespan places very severe restrictions on overall power usage. In … …Journal of Computer Science, Vol. 18, Issue 9 · 17 Sep 2022 · 5,726 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImage Compression and Reconstruction using Cubic Spline Interpolation TechniqueR. Muthaiah, K. NeelaKantan, Vidur Sharma, Amit AroraA new dimension of image compression using random pixels of irregular sampling and image reconstruction using cubic-spline interpolation techniques proposed in this paper. It also covers the wide field of multimedia communication concerned with multimedia messaging (MMS) and image transfer through mobile phones and tried to find a mechanism to transfer images with minimum bandwidth requirement. This method would provide … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,197 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Survey of Content-Based Video RetrievalP. Geetha, Vasumathi NarayananThis study surveys current trends/methods in video retrieval.

This work has done in an aim to assist the upcoming researchers in the field of video retrieval, to know about the techniques and methods … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 8,579 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStop Conditions Of BB84 Protocol Via A Depolarizing Channel (Quantum Cryptography)Iyed Ben Slimen, Olfa Trabelsi, Houria Rezig et al.BB84 (Bennett and Brassard 1984) is one of the well known protocols of quantum keys distribution. It is built to allow two interlocutors commonly called Alice and Bob to share two similar binary keys and to detect the eavesdropper presence (the eavesdropper is commonly called Eve). However, Eve presence in a disturbed environment causes errors to the sifted keys and … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 7,341 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Assessment of Water Resource Sustainability in the Upper Amojú River Basin, Northern Peruvian AndesJuan Eduardo Suarez-Rivadeneira, Freddy A. Manayay, Mayra Pamela Musayón Diaz et al.This study presents a comprehensive, statistically robust assessment of water resource sustainability in the upper section of the Amojú River Basin, Province of Jaén northern Peruvian Andes, using the Sarandón multi-cirteria methodology. A stratified convenience sample of n = 887 households distributed across 22 localities was surveyed, achieving a margin of error of ±2.61% at the 95% confidence level (finite-population … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 26 Sep 2026 · 719 accessesView PDFCite
Research ArticleOpen accessIn the abstractReclamation of Irrigated Lands and Improvement of the Groundwater Regime Under Vertical Drainage OperationBalzhan Amanbayeva, Raushan Dzhaisambekova, Alexander Basmanov et al.The aim of the study was to identify patterns of seasonal groundwater-level fluctuations and assess the effectiveness of vertical drainage in regulating the reclamation regime of saline lands in Kazakhstan. The methods included monitoring-well observations, calculation of seasonal amplitudes, Student’s t-test, the Mann-Whitney U test, and Pearson correlation analysis. Before the growing season, groundwater occurred at a depth of 1.5-1.7 … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 608 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting Corporate Financial Distress Using Explainable Machine Learning: Implications for Risk Management TechnologyKanjana Hinthaw, Warawut NarkbunnumFinancial distress prediction is a critical task in financial risk management, yet it remains challenging due to class imbalance, complex financial structures, and limited model interpretability. This study develops an integrated machine learning framework that combines feature selection, class imbalance handling, threshold optimization, and Explainable Artificial Intelligence (XAI) to improve both predictive performance and decision-making reliability. Using a dataset of … …Journal of Computer Science, Vol. 22, Issue 7 · 22 Jul 2026 · 1,130 accessesView PDFCite
Research ArticleOpen accessIn the abstractCytotoxicity Evaluation of Curcumin-FITC Conjugates in Granulosa Cells Isolated from Ovarian Follicles of Kampung Chicken (Gallus gallus domesticus)Sukarman Hadi Jaya Putra, Mansur S, UmarudinLinking curcumin to fluorescein isothiocyanate (FITC) results in a hybrid fluorescent marker (curcumin-FITC) that exhibits improved stability and sensitivity in detection. This study sought to evaluate the biological safety and cytotoxic effects of curcumin-FITC on granulosa cells obtained from ovarian follicles (2-5 mm, F1-F4 stage) of Kampung chickens. Following fluorescent labeling with different concentrations of curcumin-FITC (0-100 μg/mL), cell viability … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 14 May 2026 · 1,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Context-Aware Temporal Convolutional Network for Water Replacement Prediction in Catfish Biofloc Ponds With Imbalanced Event HandlingYaddarabullah, Inanpi Hidayati Sumiasih, Mutiara Dewi PuspitawatiWater replacement is a biologically critical yet under-automated decision in biofloc-based aquaculture systems. Mistimed actions can destabilize microbial ecosystems, elevate fish mortality, and compromise sustainability through excessive water usage. Traditional rule-based heuristics often fail to account for the nonlinear and multiscale dynamics of pond environments. To address this, we propose a Context-Aware Temporal Convolutional Network (CA-TCN), a rare-event classification framework … …Journal of Computer Science, Vol. 22, Issue 3 · 5 Mar 2026 · 1,664 accessesView PDFCite
