Several control policies of semi-active system, namely skyhook, groundhook and hybrid controls are presented using a half-car model, as a continuation of the previous work on quarter-car model. Their ride comfort, suspension displacement and road-holding performances are analysed and compared with passive system. The analysis covers both transient

In the 21st century more than ever, technology is the driving engine behind civilisations. Technology level has become an indicator of advancement and living standard. No county whatsoever can lead and prosper without owning and developing technologies locally. The first step in the take off will be to transfer the available technologies. With the

Handling and ride quality are affected by many factors, including high-frequency vibrations, body booming, body roll and pitch motion, vertical motion by the suspension system and frequency vibration transmitted from the road input excitations. This article focuses on the most significant vibration source that affects handling and ride quality, whi

Vehicles handling and ride comfort are essential subject because these vehicles operate at different environments. Improving the comfort ability enables the drivers to derive for a long time at critical situations with full activity. This paper deals with dynamics and control policies analysis of semi-active suspension systems for off-road vehicles

A Symmetric Tori connected Torus Network (STTN) is a 2D-torus network of multiple basic modules, in which the basic modules are 2D-torus networks that are hierarchically interconnected for higher-level networks. In this paper, we present the architecture of the STTN, addressing of node, routing of message, and evaluate the static network performanc

Robot motion planning between two given configurations in the time domain has a great impact on robotic applications. In the presence of link flexibility, the problem becomes more difficult and critical to be solved. A two-link flexible manipulator is proposed in this study, where the manipulator's joints are required to undergo a rest-to-rest

King Talal Dam (KTD) reservoir, Jordan's largest surface reservoir, is threatened by the activities of the catchment’s area, both domes tic and industrial, which emit untreated was te into the reservoir’s tributaries , consequently, raising the pollution and co n t aminating the water chemically and biologically. Therefore , the objective o

This book deals with the fundamentals of fluid mechanics that are taught at the undergraduate level. It can also be used as a refresher course for engineers who need to review the subject but do not have the time to go through lengthy books. The book features aspects which are not available in current textbooks, such as, it is simple, clear, brief

Vehicle models used to evaluate performance and dynamic behaviour are either discrete models, which includes quarter, half, and full car models, or continuous models using finite element modelling. In this work our focus will be on discrete models, which have more popularity with ground vehicle analysts owing to their shorter computational time and

Introduction: Guttiferae is a well-known family having a wide range of phytochemical constituents and bioactivities. Objectives: To investigate phytochemicals and bioactivities of Garcinia malaccensis. Materials and Methods: The isolated compounds were elucidated by spectroscopic methods. Antimicrobial activity was carried out by disc diffusion met
