Research ArticleOpen accessIn the abstractIntegration of Human Factor in Design Ergonomics: Example of a High Speed Train Cabin DesignHajar El M’hadi, A. CherkaouiThe development of new technologies and technical progress has accelerated man/machine substitution. Work is disappearing in its human form. This technical progress has not avoided certain catastrophes occurring. These major disasters, both for man and for the environment, took place where reliability was at its highest level. The responsibility of the operator, of the human, the weak point in these … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 30 Mar 2017 · 7,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Low Power and High Speed Comparator using MUX based Full Adder Cell for Mobile CommunicationsG. Ramana Murthy, Ajay Kumar Singh, P. Velraj Kumar, Tan Wee Xin WilsonThis paper presents an implementation of comparator (1-bit) circuit using a MUX-6T based adder cell. MUX-6T full adder cell is designed with a combination of multiplexing control input and Boolean identities. The proposed comparator design features higher computing speed and lower energy consumption due to the efficient MUX-6T adder cell. The design adopts multiplexing technique with control input to alleviate … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 16 Jan 2017 · 8,251 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeighted Integration Route to Stiffness Matrix of Quadrilaterals for Speed, Accuracy and Functionally Graded Material ApplicationSubramanian G., P.V. JeyakarthikeyanA weighted integration route with robust one-point integration (hourglass-controlled) is proposed as efficient, time saving alternative to Gauss quadrature for stiffness matrix of bilinear quadrilaterals. One-point rule relies on sampling at the center of the element to linearize the geometric transformation and average the material property over it. This enables, for a given element, explicit integration of stiffness matrix yielding … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 27 Sep 2017 · 8,050 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh-Speed for Data Transmission in GSM Networks Based on Cognitive RadioAl Smadi Takialddin, Kalid Al Smadi, Orayb O. AL-SmadiThis paper mainly studies data transmission DT rate in the modern communication systems. Increasing the need to improve the sensitivity of the control systems to detect low signals weak capacity density in view of the increasing communications systems new radio that use the capacity is decreasing and the scope of the taking of spaciousness and frequencies are on the rise. … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 3 Feb 2017 · 9,083 accessesView PDFCite
Research ArticleOpen accessIn the abstractVehicle-Fixed-Frame Adaptive Controller and Intrinsic Nonlinear PID Controller for Attitude Stabilization of a Complex-Shaped Underwater VehicleChanaka Thushitha Bandara, Lakmali Nadeesha Kumari, Sanjeeva Maithripala, Asanga RatnaweeraIn this study we present attitude stabilization using a vehicle-fixed-frame adaptive controller and an intrinsic nonlinear PID controller for a low-speed Autonomous Underwater Vehicle (AUV), of complex shape. Controlling an AUV poses a huge challenge because of the non-linearity, time variance and unpredictable external disturbance, as well as because its dynamics and hydrodynamic parameters are difficult to identify due to … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 7 Dec 2020 · 6,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractCybersecurity Mechanism for Automatic Detection of IoT Intrusions Using Machine LearningCheikhane Seyed, MBaye Kebe, Mohamed El Moustapha El Arby et al.This article proposes an ML-based cyber security mechanism to optimize intrusion detection that attacks internet objects (IoT). Our approach consists of bringing together several learning methods namely supervised learning, unsupervised learning and reinforcement learning within the same Canvas. The objective is to choose among them the most optimal for classifying and predicting attacks while minimizing the impact linked to the … …Journal of Computer Science, Vol. 20, Issue 1 · 11 Dec 2023 · 6,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractDEACT: Hardware Solution to Rowhammer AttacksTesfamichael Gebregziabher Gebrehiwot, Fitsum Assamnew Andargie, Mohammed IsmailDynamic Random Access Memory (DRAM) is a crucial component in modern computing devices. Improvements in process technology have significantly increased the speed and storage capacity of memory devices. However, as memory cells become smaller and closer to one another, annoying circuit disturbance errors such as the Row-hammer problem have become significant. Studies show that attackers can systematically exploit such errors … …Journal of Computer Science, Vol. 19, Issue 7 · 22 Jun 2023 · 6,483 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Toolkit Approach for Carbon Capture and Storage in Offshore Depleted Gas FieldRaj Deo Tewari, Tan Chee Phuat, Mohd Faizal SedaralitFossil fuels are considered a dependable, cost-effective, and efficient energy source and their utilization has resulted in tremendous growth for humanity. However, it has its downside also. Experts are of the view that present energy systems are unsustainable due to their detrimental impacts on the environment. Oil and gas producers are charged that their infrastructure, utilization of materials and technologies … …American Journal of Environmental Sciences, Vol. 19, Issue 1 · 17 May 2023 · 6,196 accessesView PDFCite
