Research ArticleOpen accessIn the abstractOptimal Parameter Tuning in a Predictive Nonlinear Control Method for a Mobile RobotD. Hazry, M. SugisakaThis study contributes to a new optimal parameter tuning in a predictive nonlinear control method for stable trajectory straight line tracking with a non-holonomic mobile robot. In this method, the focus lies in finding the optimal parameter estimation and to predict the path that the mobile robot will follow for stable trajectory straight line tracking system. The stability control contains … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Apr 2006 · 7,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Neural Network for Generating Adaptive LessonsHassina Seridi-Bouchelaghem, Toufik Sari, Mokhtar SellamiTraditional sequencing technology developed in the field of intelligent tutoring systems have not find an immediate place in large-scale Web-based education. This study investigates the use of computational intelligence for adaptive lesson generation in a distance learning environment over the Web. An approach for adaptive pedagogical hypermedia document generation is proposed and implemented in a prototype called KnowledgeClass. This approach … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 7,274 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of a New Network-enabled Solver for the Assignment Problem in Computer-aided EducationAndreou Dimitrios, Paparrizos Konstantinos, Samaras Nikolaos, Sifaleras AngeloThis study present a new learning tool developed for the visualization of an algorithm for the assignment problem. We show how the teaching of an algorithm can be greatly enhanced and the tutor's effort decreased with a visualization tool that provides an interactive and animated view of the subject being taught to the students. This tool makes use of the … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,821 accessesView PDFCite
Research ArticleOpen accessIn the abstractBinding of the scutellarin to albumin using tryptophan fluorescence quenching, CD and FT-IR spectraJianniao Tian, Jiaqin Liu, Zhide Hu, Xingguo ChenThe binding of scutellarin with bovine serum albumin (BSA) was investigated at three temperatures, 296k, 310K, and 318K, by the fluorescence, circular dichroism (CD) and fourier transform infrared spectroscopy (FT-IR) at pH 7.40. The binding parameters were determined by Stern-Volmer equation. The thermodynamic parameters were calculated according to the dependence of enthalpy change on the temperature as follows:ΔH0 and ΔS0 … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 13,649 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Flywheel with a Moving HoleJihad Said AddasiA special apparatus has been designed to study linear, circular, and rotational motions. This apparatus consists of a flywheel, rotating in horizontal plane by the mean of a hanging mass. This flywheel carries a hole, which can be moved on a radial rail. This hole can be fixed at desired distance from the flywheel axis. Putting a metallic sphere on … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,890 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation of the Nature Properties of PlasmaPeter Evans, Frederick Osman, Heinrich HoraThis study presents the characteristics of the plasma and the effect of the laser beam to best suit the plasma model behavior. Special attention is paid to the “Genuine” Two Fluid Model and the ponder-motive and transient forces. These models are translated into a numerical study of the parameters, such as the electric field density and temperature distributions once electromagnetic … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,568 accessesView PDFCite
Research ArticleOpen accessIn the abstractVoronoi Partition to Support Data Search in Uncertain Database with k-Bound FilteringSlamet Sudaryanto Nurhendratno, Sudaryanto, Solichul HudaWith the development of mobile technology, one of its main functions is to have mobile navigation capabilities, this is one of the Location-Based Services (LBS). Mobile navigation is designed as a mobile device to be able to monitor access objects from users. Because of the mobile characteristic, the impact on the points of objects to be found always occur a … …Journal of Computer Science, Vol. 16, Issue 12 · 22 Dec 2020 · 6,651 accessesView PDFCite
Review ArticleOpen accessIn the abstractAbout Supersonic Flight and Mach 3 FlyingRelly Victoria Virgil PetrescuAerospace-BAC Concorde was a supersonic passenger aircraft. It was the result of a government treaty between the French and British governments, combining the efforts of Aerospace and British Aircraft Corporation. With only 20 aircraft built in total, the cost of the development phase was a major economic failure. In addition, Air France and British Airways were subsidized by the government … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 8,934 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of IncL/M Plasmids Using the Neighbor-Joining Method on Basis repA and excA GenesTouati Abdelaziz, Mairi AssiaThe aim of this study is to make comparison of IncL/M groups on basis of two genes candidates’ repA and excA genes. The sequences of 27 plasmids were compared using the neighbor-joining method. This method was used to construct a phylogenetic tree for the nucleotide sequences of two genes (repA and excA), using the program MEGA X software. The evolutionary … …Current Research in Bioinformatics, Vol. 8, Issue 1 · 27 Feb 2020 · 7,095 accessesView PDFCite
Review ArticleOpen accessIn the abstractSpace ProbesRelly Victoria Virgil PetrescuA space probe is an unmanned space vehicle launched into space to study more or less distant different celestial objects: The Sun, the planets, dwarf planets and small bodies, their satellites, the interplanetary medium or the interstellar medium. A space probe is distinguished from other unmanned spacecraft that remain in Earth orbit. Space probes can take a large number of … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 21 May 2019 · 7,423 accessesView PDFCite
