A Hybrid Energy System (HES) is a mechanism that combines multiple sources of energy connected together to achieve synchronised energy output. However, increased energy consumption, operator energy expenses, and the potential environmental impact of increased emissions from the exhaustion of non-renewable energy resources (fossil fuel) pose major challenges to HES. This research is to conduct energy management strategy based on a demand response (DR) program and a hydrogen storage system by designing a Program Logic Controller (PLC) unit. The hybrid system is evaluated by comparing different scenarios such as a hydrogen energy system and demand response. The purpose of this research is to reducing peak demand, minimise the cost of the system and also to extract surplus power generation out of the rate of the battery. This can be achieved by improving the system performances and by eliminating any degradation at the early stages. Organisations or companies must be sure their systems are working properly and that their investments will pay off.
This paper explores the use of active thermography technique for Kenaf-Polyurethane (PU) composites. Presently the industry is going toward environmental friendly materials, so investigating more methods in quality control of products is an essential issue. Thermography has potential to detect the defects in-depth. The samples were manufactured by a hand lay-out method and use of a hot press to produce the composites. This method proves that the defects of Kenaf-PU boards are dependent on the amount of fiber and the thickness of the boards. Non-destructive infrared thermography technique has the capability of detecting the defects in Kenaf-PU boards. This study demonstrates evidence that this method can investigate some defects such as voids and kenaf fiber pulled out from its original place with an accuracy of 90%.
In the current competitive environment, financial performance plays a vital role in evaluating an entity, and ethical climate and ethical behavior are important variables that affect financial performance. Therefore, the present study aimed to explore the effect of ethical climate on financial performance mediated by ethical behavior. The present applied research is descriptive in type. The statistical population included 234 financial managers of Toos Industrial town in Mashhad-Iran, and 116 subjects were selected for the study using a random sampling method. To collect the required data, standard questionnaires of ethical climate, ethical behavior and financial performance were used and to analyze the findings, structural equation modeling (SEM) was used. The SEM results showed that the ethical climate has a positive and significant effect on financial performance and the strength of this effect is increased when mediated by ethical behavior.
Agriculture has always been one of the most important issues for humankind. During past decades while robotics technologies have been introduced to many industries, agricultural scientists also made advantages of it and improved agricultural methods and products. In this paper the main advantages of the robotics in agriculture by far is presented. The robots that have been used in agricultural researches can be categorized in 4 main types; path navigators, harvesting robots, crop disease detectors and weed detectors which are studied in this paper.
<p>This paper presents a brief survey on multi-legged robots and their applications in agriculture such as for harvesting. Multi-legged robots have the benefit of more flexibility and adapt to different rough terrain in a better way. They also have very important applications in fulfilling the dangerous tasks such as mine detecting.</p>
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.
