Industrial tank system is widely used in consumer liquid processing and chemical processing industry. In liquid-based product manufacturing system, one of the main components consists of an industrial tank. This paper explores the applications of two swarm intelligence algorithms in optimizing the PID controller parameters. These swarm intelligence algorithms are Particle Swarm Optimization (PSO) and Firefly Algorithm (FA). Each agent of the swarm intelligence will represent a possible solution of the problem where each dimension corresponds to the PID controllers parameters. Result obtained shows that there are potential in improving these algorithms to replace the conventional way of obtaining PID controllers parameters
The price of the wood according to the type of wood. Classification of the woods can be done by studying its texture. This paper introduces Fuzzy k Nearest Neighbor to classify 25 types of wood. The woods images have been taken from the Wood Database of the Centre for Artificial Intelligence & Robotics, Universiti Teknologi Malaysia. The features of wood images are extracted using Local Binary Pattern. The results of this paper shows improvement in wood classification compare to the previous literature.
This paper examines the role of social trust in influencing ethical work climate and decision-making. Moderated regression analysis was used to analyse the data. A survey was carried out at the Ministry of Entrepreneur and Cooperative Development (MECD) in Malaysia, and was completed by all 349 employees, which permitted a comprehensive overview. We found that company interest, friendship, team play, and personal morality were closely related to increasing social trust (p <0.05). Social trust also mediated a positive impact of company interest, friendship, team play, and personal morality on decision-making with p <0.05. Rules and procedures had no significant impact either on social trust or decision-making. Eight hypotheses were confirmed, while two were rejected. Implications for practice and research are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
