Research ArticleOpen accessIn the abstractNumerical Study of Static and Dynamic Instabilities of Pinned-Pinned Pipe under Different ParametersDahmane Mouloud, Zahaf Samir, Benkhettab Mohamed, Boutchicha DjilaliIn this study, the natural frequencies of the pipe transporting an fluid resting on an elastic Winkler-type and the critical velocities of instabilities are obtained by the standard finite element method. A dynamic characteristic of a pipe carrying internal fluid undergoes mechanical load due to inertia effect of fluid, Coriolis force, fluid kinetic force due to fluid flow velocity, dynamic … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 21 Nov 2020 · 7,012 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Study of Post-Buckling of Clamped-Pinned Pipe Carrying Fluid Under Different ParametersDahmane Mouloud, Samir Zahaf, Mawhoub Soubih et al.This research aims to calculate the first three natural frequencies and critical velocity of a fluid-conveying pipe are obtained with numerical approach with standard finite element method and this by discretizing the structure wall and internal flow, starting from beam type with two degrees of freedom per node. The determination is done to the vibrational equation from the fluid-structure coupling … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 21 Sep 2020 · 12,084 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling the Semantics of States and State MachinesSabah Al-FedaghiA system’s behavior is typically specified through models such as state diagrams that describe how the system should behave. According to researchers, it is not clear what a state actually represents regarding the system to be modeled. Standards do not provide adequate definitions of or sufficient guidance on the use of states. Studies show these inconsistencies can lead to poor … …Journal of Computer Science, Vol. 16, Issue 7 · 14 Jul 2020 · 6,979 accessesView PDFCite
Research ArticleOpen accessIn the abstractThinging-Based Conceptual Modeling: Case Study of a Tendering SystemSabah Al-Fedaghi, Esraa HaidarIn computer science, models are made explicit to provide formality and a precise understanding of small, contingent “universes” (e.g., an organization), as constructed from stakeholder requirements. Conceptual modeling is a fundamental discipline in this context whose main concerns are identifying, analyzing and describing the critical concepts of a universe of discourse. In the information systems field, one of the reasons … …Journal of Computer Science, Vol. 16, Issue 4 · 15 Apr 2020 · 7,952 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersonal Legacy Information Management System for Muslim in Malaysia: A Preliminary DesignHanis Salwan Mobidin, Rossilawati Sulaiman, Zarina Shukur, Noorazean Mohd AliThere is an alarming amount of frozen and unclaimed assets in Malaysia. Among the factors that contribute to this situation is the failure of the decedent to leave a will to the heirs of the estate or to leave the important documents necessary to initiate the distribution of the estate. This lack of preparation will inimitably put the heirs in … …Journal of Computer Science, Vol. 15, Issue 12 · 4 Dec 2019 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Models for Rigid Memory MechanismsRelly Victoria Virgil PetrescuThe paper presents a dynamic model that works with variable internal damping, applicable directly to rigid memory mechanisms. If the problem of elasticity is generally solved, the problem of system damping is not clear and well-established. It is usually considered a constant "c" value for the internal damping of the system and sometimes the same value c and for the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 6 May 2019 · 5,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeveloping a Prototype for Sun Tracker System Based on IoT: Controlled by Mobile App and Online Database MonitoringIsmail Ismail Yusuf Panessai, Muhammad Modi bin Lakulu, Siva Kumar A/L Subramaniam et al.IoT (Internet of Things) has become a separate research field since the development of internet technology and other communication media. IoT optimizes several tools such as sensor media radio frequency identification, wireless sensor networks and other smart objects that allow humans to easily interact with all devices connected to the internet network. The purpose of this research is to build … …American Journal of Applied Sciences, Vol. 16, Issue 1 · 11 Feb 2019 · 8,770 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Dynamic Boot Loader for Loading an Operating SystemAlycia Sebastian, Dr. K. Siva SankarBoot Loader is the crucial program that loads the operating system in memory and initializes the system. In today’s world people are constantly on move and portable system are in demand specially the USB devices due to its portability and accessibility compared to CD/DVD drives. The purpose of this paper is to design a dynamic boot loader which removes the … …Journal of Computer Science, Vol. 15, Issue 1 · 28 Jan 2019 · 8,311 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Static Analysis of Android Source Code for Lifecycle Development Usage PatternsNoura Hoshieah, Samer Zein, Norsaremah Salleh, John GrundyBuilding robust Android apps is a non-trivial task that requires skilled developers to understand various Android platform peculiarities. However, among the Android developers community, a large fractions are considered to be novice and inexperienced developers. One of the main peculiarities in the Android app development is the activity lifecycle model. A developer needs to have deep understanding of the different … …Journal of Computer Science, Vol. 15, Issue 1 · 10 Jan 2019 · 8,669 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 · 463 accessesView PDFCite
