Research ArticleOpen accessIn the keywordsThe Effect of Water on The Strength of Building StonesBellopede Rossana, Marini PaolaProblem statement: Water is one of the main causes of stone decay and the presence of water alone inside a stone could cause a decrease in its mechanical strength. In order to study the effect of water on the mechanical strength of stones, three Italian stones, which have historically been used for balconies, have been studied: Pietra di Luserna, Pietra … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 17 Mar 2012 · 7,032 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRecycled High-Density Polyethylene and Rice Husk as a Wetted Pad in Evaporative Cooling SystemNitipong Soponpongpipat, Sukum KositchaimongkolProblem statement: The low cost and easy-to-find materials, for being used as wetted pad of evaporative cooling system, are necessary for agriculture. This study, thus, studied the evaporative cooling efficiency and pressure drop of recycled High-Density Polyethylene (HDPE) and rice husk as a wetted pad in evaporative cooling system. Approach: The study was done by establishing the tested wetted pad … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 8,697 accessesView PDFCite
Research ArticleOpen accessIn the keywordsElectric Power System Under-Voltage Load Shedding Protection Can Become a TrapLuiz Augusto Pereira Fernandes, Alexandre Rocco, Heraldo Silveira Barbuy, Geraldo Caixeta GuimarãesProblem statement: Under-Voltage Load Shedding (UVLS) protection of Electric Power Systems (EPS) is frequently used against Voltage Collapse (VC), however when there is automatic bus voltage regulation with excessive capacitive compensation, the UVLS scheme may not trip. In this case, load shedding must be based in a Voltage Collapse Proximity Indicator (VCPI). Many UVLS procedures may not be appropriate today. … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,203 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPresence and Origin of Fluoride in the Complex Terminal Water of Ouargla Basin (Northern Sahara of Algeria)Imed Eddine Nezli, Samia Achour, Mohamed Djidel, Saïd AttalahProblem statement: The underground waters in the oriental regions of the Algerian Sahara, present real chemical quality problems. Their content in fluorides always exceeds the limit of the recommended levels. That is 0.8 mg L-1, according to the maximum temperature in the region. Combined to a high salinity, it affects the health of the population living around the region. The … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,671 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUsing Look-up Tables to Model an Electromagnetic Suspension SystemMusaab HassanProblem statement: The aim of the study was to model an electromagnetic suspension system. The electromagnetic system consists of an electromagnet which was attracted an iron object which was freely suspended in air. Approach: Modelling a magnetic system requires modelling the magnetic force characteristics and the flux characteristics. The force characteristics were to be produced from a nonlinear flux characteristic-current. … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 21 Jun 2012 · 6,889 accessesView PDFCite
Research ArticleOpen accessIn the keywordsContribution to the Study of the Origin of Salinity in Alluvial Aquifer System in the Ain chabro-Hammamet (North-East ALGERIA)K. Seghir, N. KhériciTebessa is located in the Algerian North East. It is characterized by a semi-arid continental climate with an average interannual precipitation of less than 400 mm. It belongs to the Eastern Saharian Atlas field along the Tunisian borders. It is drained by a certain number of the wouady of which Chabro and Bouakous are the most important. The surface area … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,608 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Dynamically Zero Trust and Risk Aware Cryptographic Orchestration Framework of Secure Multi Cloud Electronic Health RecordsD. Veerabhadra Rao, G. Appa Rao, S. AnuradhaThe adoption of multi-cloud infrastructures for Electronic Health Records (EHRs) improves scalability and accessibility but introduces security challenges such as fragmented trust management, high cryptographic overhead, and inefficient integrity verification. Existing frameworks rely on static authorization and uniform encryption mechanisms, which fail to dynamically evaluate behavioural risks associated with user access requests. Consequently, Distributed Trust Inconsistency, Cryptographic Scalability Saturation, and … …Journal of Computer Science, Vol. 22, Issue 10 · 7 Oct 2026 · 453 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Agile Leadership in Team Motivation Within Software Development Projects: A Study Case of Multinational Companies in MoroccoMaha Makkass, Youness Laghouaouta, Adil AnwarToday’s business world is increasingly competitive, especially in the software development domain. This growing pressure has led many organizations to adopt agile methodologies and cultures. They need innovations to respond quickly to the sudden changes that are most of the time not part of any leader's strategic plan. In these agile contexts, which are supposed to be built with self-managed … …Journal of Computer Science, Vol. 21, Issue 11 · 12 Feb 2026 · 1,739 accessesView PDFCite
Research ArticleOpen accessIn the abstractInternet of Things Based COVID-19 Patient in Self-Isolation Monitoring SystemBagaskara Akbar Fadhlillah, Ditdit Nugeraha UtamaSelf-isolation has become a critical measure for managing symptomatic or asymptomatic COVID-19 patients, particularly when healthcare facilities are overwhelmed. This study explores a monitoring system based on commercially available Wear OS smartwatches designed to track patient vital signs, specifically oxygen saturation (SpO₂), heart rate, and location, and generate alerts during atypical events. The research has two primary objectives, first, to … …Journal of Computer Science, Vol. 21, Issue 12 · 12 Feb 2026 · 1,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 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 PDFCite
