Energetic and exergetic aspects of solar air heating (solar collector) systems

Abstract: Solar air heating (solar collector) is a renewable heating technology and provides heat using solar energy. With fuel costs and other factors, solar air heaters (SAHs) are getting more attention. The energetic and exergetic performance of SAHs is influenced by a number of factors. The present study reviews the previously conducted studies and applications in terms of design, performance assessment, heat transfer enhancement techniques, experimental and numerical works, thermal heat storage, effectiveness compassion and recent advances. It may be concluded that energy analysis method has been used in a number of studies while exergy analysis method has been applied to the relatively low numbers of systems. Energy efficiencies of solar air collectors reviewed varied from 47% and 89%. It is expected that this comprehensive study will be very beneficial to everyone involved or interested in the energetic and exergetic design, simulation, analysis, test and performance assessment of SAHs.

A local-best harmony search algorithm with dynamic subpopulations

Abstract: This article presents a local-best harmony search algorithm with dynamic subpopulations (DLHS) for solving the bound-constrained continuous optimization problems. Unlike existing harmony search algorithms, the DLHS algorithm divides the whole harmony memory (HM) into many small-sized sub-HMs and the evolution is performed in each sub-HM independently. To maintain the diversity of the population and to improve the accuracy of the final solution, information exchange among the sub-HMs is achieved by using a periodic regrouping schedule. Furthermore, a novel harmony improvisation scheme is employed to benefit from good information captured in the local best harmony vector. In addition, an adaptive strategy is developed to adjust the parameters to suit the particular problems or the particular phases of search process. Extensive computational simulations and comparisons are carried out by employing a set of 16 benchmark problems from the literature. The computational results show that, overall, the proposed D...

The extended theory of planned behavior in Turkish customers' intentions to visit green hotels

Abstract: Over the last decade, many studies have started to focus on understanding customers' green purchase intentions since the increasing importance of environmental issues in the hotel industry. This study examined customers' intentions to visit green hotels by using the theory of planned behavior. Two constructs, environmentally friendly activities and overall image, were incorporated into the theory, and the extended theory of planned behavior model was tested. The aim of this study was to analyze the effects of the extended theory of planned behavior constructs (attitudes towards green hotels, subjective norms, perceived control, environmentally friendly activities, and overall image) on visit intentions and also to predict the effects of visit intentions on willingness to pay, satisfaction, and loyalty. Within this aim, the research model was formed to show the antecedents and consequences of intentions to visit green hotels. Data were collected by face‐to‐face survey technique, and 400 usable questionnaires were held from the customers in Izmir City, Turkey. In the findings, four of five constructs in the antecedents of intentions, except perceived control, were found as significant, and all three consequences of intentions were found as significant. The results of the study supported the usage of the extended theory of planned behavior in the context of green hotels. Theoretical contributions and discussions were explained lastly.

Psychological correlates of COVID-19 conspiracy beliefs and preventive measures: Evidence from Turkey.

Abstract: COVID-19 pandemic has led to popular conspiracy theories regarding its origins and widespread concern over the level of compliance with preventive measures In the current preregistered research, we recruited 1088 Turkish participants and investigated (a) individual differences associated with COVID-19 conspiracy beliefs; (2) whether such conspiracy beliefs are related to the level of preventive measures; and (3) other individual differences that might be related to the preventive measures Higher faith in intuition, uncertainty avoidance, impulsivity, generic conspiracy beliefs, religiosity, and right-wing ideology, and a lower level of cognitive reflection were associated with a higher level of belief in COVID-19 conspiracy theories There was no association between COVID-19 conspiracy beliefs and preventive measures while perceived risk was positively and impulsivity negatively correlated with preventive measures We discuss the implications and directions for future research
