This paper presents an investigation into dynamic simulation and controller optimization based on genetic algorithms (GAs) for a single-link flexible manipulator system in vertical plane motion. The dynamic model of the system is derived using the Lagrange equation and discretised using the finite difference (FD) method. GA optimization is used to

In this research, particle swann optimisation (PSO) and genetic algorithm (GA) are used to model a single-link flexible manipulator. Investigations focus on characterizing the system from input torque to hub-angle, hub-velocity and end-point acceleration. A simulation environment characterizing the system behaviour in vertical motion is used as a p

Background The quinoline alkaloids are a group of alkaloids with diverse structural types. The 4-oxygenated quinolone and 2-substituted 4-quinolone are the types of quinoline alkaloids that possess the chromophore structures which are similar to the pharmacophore of the conventional 4-quinolone antimicrobial agents. Therefore it is presumed that th

Islamic banking started with the objective of providing a banking system that conforms to the Shari'h, with the absence of interest or riba. Nonetheless, it has increasingly become evident that a convergence is taking place between the conventional and Islamic banking systems. Indeed, most Islamic financial contracts are now tied to the market

Purpose: This study aims to review the current practices of micro credit and micro financing in several Muslim countries namely Bangladesh, Pakistan, Sudan, Malaysia and Indonesia. Design/Methodology/Approach: The methodology used in this research is mainly literature review. Finding : This study found that the practices of micro credit and micro f

The world is reacting in many ways to the ongoing global economic crisis - quantitative easing, fiscal stimuli, currency swaps in trades, issuance of local currencies, opening gold markets and so on. The crisis is, unfortunately, still ongoing because the US, being a significant economy, is yet to recover from the crisis triggered by the collapse o

This study uses econometric models to evaluate the economic perlormance of clients participating in the microcredit program of Amanah Ikhtiar Malaysia (AIM). Several proxies are used for the economiSJ performance variable (dependent variables), such as level of earnings/income, ratio of spending to income and value of assets. The regressors (indepe

Background: Superselective embolisation has been recognised as integral in the management of lower gastrointestinal haemorrhage. It has also reduced the need for emergency surgery. The objective of this case series was to describe the lower gastrointestinal haemorrhage cases seen in our centre, its diagnosis and the role of superselective embolisat

In the present study hypersonic similitude has been used to obtain stability derivatives in pitch and roll of a delta wing with curved leading edges for the attached shock case. A strip theory is used in which strips at different span-wise locations are independent. This combines with the similitude to give a piston theory. The present theory is va
