Research ArticleOpen accessIn the abstractMulti-Source Cyber Intrusion Detection Using Ensemble Machine LearningTaskeen Ali Khan, Sara Abbas, Biswaranjan Senapati et al.The increased usage of digital technologies across businesses has led to an increase in cybercrime. It is difficult for existing intrusion detection systems to detect highly skilled hacking attempts; however, machine learning has been suggested as a way around these drawbacks. The purpose of this study is to evaluate how well various machine learning algorithms identify and stop cyberattacks in … …Journal of Computer Science, Vol. 21, Issue 1 · 14 Dec 2024 · 5,705 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Comprehensive Survey on Applications, Challenges, Threats and Solutions in IoT Environment and ArchitectureSadia Waheed, Savera Hanif, Rubab Hafeez et al.The influence of the Internet of Things (IoT) on how people live, interact and conduct business has rapidly increased. Integrating physical objects with electronic networking, or the Internet of Things (IoT), allows for better communication and environment detection. In coming years, higher service levels will be offered by IoT-based technologies, remarkably changing how people would conduct their daily lives. Currently, … …Journal of Computer Science, Vol. 20, Issue 3 · 30 Jan 2024 · 7,272 accessesView PDFCite
Research ArticleOpen accessIn the abstractBridging Traditional Craftsmanship and Digital Interaction through User-Centered Design: Designing Intuitive InterfacesChristopher Kevin Gunawan, Ravi Ardiza Putra, Steven Albert et al.Traditional craftsmanship served as both a manifestation of cultural heritage and a vital pillar of the global creative economy. However, its digital integration was frequently hindered by low technological literacy and misalignment between manual practices and standardized digital systems. Existing digital interventions primarily focused on passive e-commerce storefronts and often ignored the socio-economic precarity of craftsmen operating as independent contractors … …Journal of Computer Science, Vol. 22, Issue 6 · 5 Jun 2026 · 1,559 accessesView PDFCite
InvestigationOpen accessIn the abstractSimulation and Experimental Analysis of a Demonstrative Solar Heating and Cooling Plant Installed in Naples (Italy)Annamaria Buonomano, Francesco Calise, Massimo Dentice d'Accadia et al.In this study the model of a Solar Heating and Cooling (SHC) system and its experimental setup are presented. The SHC system under investigation is a demonstration plant installed in Naples, based on flat plate solar collectors and a single-stage LiBr-H2O absorption chiller. In addition, two vertical tanks are installed as storage system. The balance of system includes: A cooling … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 10 Oct 2016 · 7,809 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Optimal Incoherent Subcarrier Tracking of BOC(1,1) Navigation SignalsAlexandr Ivanovich PerovNavigation receivers of global positioning systems that are operated in complex electromagnetic environment must have an increased noise immunity characteristic. One way of such noise immunity rising is to use incoherent operating mode of navigation receiver. There are known processing algorithms for navigation signals with Binary Phase Shift Keying (BPSK) modulation. But in the near-term outlook Global Navigation Satellite Systems … …American Journal of Applied Sciences, Vol. 13, Issue 9 · 26 Sep 2016 · 7,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Simulation and Optimum Operation Strategy of a Trigeneration System Serving a HospitalFrancesco Calise, Massimo Dentice d'Accadia, Luigi Libertini et al.This paper presents a numerical analysis of a trigeneration system in a hospital, aiming at determining the cost-optimal operating strategy as a function of the energy demands to be matched. The system includes: A natural gas fired reciprocating engine, heat exchangers for waste-heat recovery, a single-stage LiBr-H2O Absorption Chiller (ACH), a cooling tower, pumps, a backup boiler, a backup vapour-compression … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 29 Aug 2016 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Model of Calcium Carbonate System of Soil SolutionAbdulmalik A. Batukaev, Anatoliy P. Endovitsky, Andrey G. Andreev et al.Carbonate system determines the basic processes of soil formation and evolution. The aim of research was to show the importance of chemical Carbonate Calcium Equilibrium (CCE) in soil solutions. CCE causes a degree of soil solution’s saturation with CaCO3 as a factor of carbonate geochemical cycle. CCE depends on chemical composition, pH, Eh, buffering properties of liquid phase, dissolution, migration, … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 18 May 2016 · 7,981 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of a Machine Tool Spindle Critical Frequency through Modal and Imbalance Response AnalysisKhairul Jauhari, Achmad Widodo, Ismoyo HaryantoThe most important part for machine tool system is spindle system. The structural properties of spindle will affect to the productivity of machining process and the work pieces quality. Thus it is necessary and very important to know its spindle dynamic behaviors for avoiding forced vibration due to resonance. The Finite Element Method (FEM) has been adopted for obtaining spindle … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 14 Feb 2016 · 8,597 accessesView PDFCite
HypothesisOpen accessIn the abstractReal-Time Automatic Inspection System for the Classification of PCB Flux DefectsAng Teoh Ong, Aouache Mustapha, Zulkifilie Bin Ibrahim et al.Automatic inspection based on a real-time machine vision system may serve as substitute for the manual human visual inspection of flux defects in Printed Circuit Boards (PCBs), which often cause damage on the board in the form of corrosions that harm the assembly. The concept of automatic inspection contributes to the improvement of the manufacturing quality of PCBs and facilitates … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 25 Aug 2015 · 8,712 accessesView PDFCite
Research ArticleOpen accessIn the abstractProfitability and Financial Sustainability Analysis in Italian Aquaculture Firms by Application of Economic and Financial MarginsMattia Iotti, Giuseppe BonazziAgricultural Firms operating in the aquaculture sector in Italy are often characterized by high investment and high capital intensity. In fact, these companies need to develop structures and breeding systems to generate adequate cash flow to repay their investment in fixed assets. In addition, the biological cycle of breeding further extends the need for capital, in this case to finance … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 1 · 2 Apr 2015 · 8,440 accessesView PDFCite
