The University of Kocaeli is a state university in Kocaeli, Turkey. It was founded as the Academy of Engineering and Architecture of Kocaeli in 1976. The electrical and mechanical engineering departments, basic science, and department of modern languages were the original departments of the academy. It became a part of Yıldız University in 1982.On July 1992, the Turkish government decided to build 22 universities nationwide, including Kocaeli University. Before the 1999 İzmit earthquake, which can be regarded as the turning point for the rebirth of the university, Kocaeli University had approximately 20,000 students, 1,150 educational staff and a campus of 650,000 square meters. Kocaeli University lost nearly 75% of its physical structure in the earthquake, but its prior expansion site Arslanbey Campus rapidly compensated for the university's losses.The university moved to Umuttepe Campus in 2004.Kocaeli University's central Umuttepe Campus is located just outside of Izmit in the region of Kocaeli, the most heavily industrialized region of Turkey. Most of its faculties are in this campus, except the Faculty of Fine Arts, the Faculty of Architecture & Design, the Faculty of Dentistry, and the Faculty of Animal Husbandry.Istanbul is only 90 kilometres away, and its secondary international airport was developed on a site 50 kilometres from Izmit, making the university much more accessible in recent years. Since Kocaeli is a near neighbour of Istanbul, a large number of its students come from Istanbul.The university has established a department of international relations which monitors Bologna developments closely and oversees KOU's participation in the Erasmus and Leonardo da Vinci student mobility schemes. With membership in the European University Association, KOU is aiming for greater international recognition of its academic work.The university, while focusing on technical and engineering subjects, offers an extensive selection of courses in social science and arts as well. Some steps toward certification by ABET are being taken by the Faculty of Engineering, such as adaptation of course content in engineering majors. Wikipedia.

Manganese(III) acetate based radical cyclization of various fluorinated 1,3-dicarbonyl compounds with 2-thienyl and 2-furyl substituted alkenes produced 3-trifluoroacetyl and 2-trifluoromethyl-dihydrofurans in good yields. The radical cyclizations of 2-methyl-5-[(E)-2-phenylvinyl]furan 2b and 2-[(E)-2-phenylvinyl]thiophene 2c led to the formations of 5-(5-methyl-2-furyl)- 4,5-dihydrofuran and 5-(2-thienyl)-4,5-dihydrofuran, respectively. In the reactions of 1,3-dicarbonyls with alkenes, 2-thienyl substituted alkenes formed 4,5-dihydrofurans in higher yields than 2-furyl substituted alkenes. © 2011 Elsevier Ltd. All rights reserved.

Supplier evaluation and selection process has a critical role and significant impact on purchasing management in supply chain. It is also a complex multiple criteria decision making problem which is affected by several conflicting factors. Due to multiple criteria effects the evaluation and selection process, deciding which criteria have the most critical roles in decision making is a very important step for supplier selection, evaluation and particularly development. With this study, a hybridization of fuzzy c-means (FCM) and rough set theory (RST) techniques is proposed as a new solution for supplier selection, evaluation and development problem. First the vendors are clustered with FCM algorithm then the formed clusters are represented by their prototypes that are used for labeling the clusters. RST is used at the next step of modeling where we discover the primary features in other words the core evaluation criteria of the suppliers and extract the decision rules for characterizing the clusters. The obtained results show that the proposed method not only selects the best supplier(s), also clusters all of the vendors with respect to fuzzy similarity degrees, decides the most critical criteria for supplier evaluation and extracts the decision rules about data. © 2012 Elsevier B.V.

Resilience is frequently viewed as an indicator of good adjustment following adversity such as traumatic events. Connor and Davidson (2003) developed a brief self-report scale to quantify resilience over 1000 participants. We collected the data from individuals who are exposed to devastating earthquakes that occurred in 1999 in Turkey. A total of 246 earthquake survivors from the disaster area, with the mean age 35.80 (S.D.= 8.6), completed the Turkish version of CD-RISC. The purpose of the study is to validate factor structure of the scale through exploratory and confirmatory factor analysis using a Turkish sample. In this investigation 52% of the total variance was accounted for by three factors and the obtained factor structure was verified through confirmatory factor analyses. The results indicated that there was no statistical gender difference with regard to the Turkish version of CD-RISC scores. The Turkish version of the scale obtained a Cronbach alpha coefficient of 0.92. The results showed that the Turkish version of the CD-RISC is a valid and reliable measure of resilience. © 2009 Elsevier Ireland Ltd. Source

This paper presents an optimization problem for the 3-degrees-of-freedom RRR fully planar parallel manipulator (3-RRR) based on the actuator power consumption. The optimization purposes to determine the optimal link and platform masses in order to minimize the electrical energy consumed by the actuators subject to the kinematic, geometric and dynamic constraints. The Particle Swarm Optimization (PSO), increasingly being used in various engineering applications, has been considered as the optimization tool. A discrete-time PID control scheme is designed for demonstrating the energy saving by means of the mass optimization. Finally the optimization results for the eight working modes of 3-RRR have been compared to each other and given in tables. © 2012 Elsevier Ltd. Source

Energy is indispensable for human life. Energy is not only a measurement for economical and social improvement but also a fundamental human necessity. Every country in the planet are trying to find a way to solve energy problems such as depending on energy importation, all kind of environmental pollution, global warming, increasing cost of energy, and energy inefficiency. Industrial and technologic developments are continuing rapidly, the need of energy consuming is increasing accordingly, and also concerning the population increase; the governments are given vast amount of incentives for renewable energy for the solutions to these kinds of problems and for the aims to be realized, which are saving money, saving energy and therefore saving the world. In this study, recent renewable energy developments, the evaluation of renewable energy, the importance of renewable energy use, the incentives and subsidies, the renewable energy policies in Turkey are investigated. In this regard some barriers and recommendations are submitted. © Sila Science. Source
