With the discovery of inorganic semiconductors, silicon and germanium became very important materials in the field of electronics. The use of these materials with these limited features for a long time has become insufficient in the face of increasing demands. For this reason, organic semiconductors have revolutionized structures that respond to these demands. In this study, we synthesized ZnO based semi-material with the hydrothermal method. Structural characterizations were made by XRD, SEM (EDX) and FTIR.

The institutions that take the leading role in the evaluation of the real estate should be determined. Real estate valuation takes place in a multi-headed organizational structure and is benefited from institutions in both the public and private sectors. The method of determining the institutions will be examined through the social network analysis methodology of the network of relations between public institutions and the private sector. With the numerical and visual analyzes the following questions will be examined: "Which is the director and responsible institution to undertake the task of collecting the institutional structure under one roof?", Which is the institution that uses the real estate appraisal results most in their works?, Which institution is the most cooperating in acquiring data on real estate appraisal?, Which are the most known institutions that make real estate appraisal?, Which of the institutions that make real estate appraisal are most trusted?”. The study will be conducted in order to find answers given to the related questions. As a result, relations between institutions engaged in real estate appraisal business are assessed by social network analysis and interoperability issuing "awareness network" will be put forward.

Modeling and simulation are prerequisite to analysis and design of engineering systems. Modern engineering systems often are multy disciplinary, i.e., may include blocks from different majors of engineering, such as electrical, mechanical, fluid, etc. Availability of a unified approach for system modeling will make it easy for engineers or researcher from a certain discipline to model the systems from other disciplines. For example, with availability of a unified modeling methodology an electrical engineer will be able to model a system composed of electrical, mechanical and fluid systems. Modeling of complex mechanical systems is not always easy for engineers from other disciplines. On the other hand, it is much easier to establish mathematical model of electric circuits. Furthermore, simulation software is much richer for electric circuits. Therefore, in this paper a methodology is proposed for unifying the modeling of electrical and complex mechanical systems by obtaining electric circuit model of complex mechanic systems. In developing the proposed methodology, analogy between the electrical and mechanical elements have been used as tools. Proposed methodology has been applied to modeling and simulation of a relatively complex mechanical system and benefits accrued from this approach has been discussed. It is further proposed that the approach presented in this paper can be easily extended to modeling of dynamic systems from other engineering disciplines.

This study aims to evaluate the hazards of the stainless tank production process in a company by using the Integrated Analytic Hierarchy Process (AHP) and Failure Mode and Effect Analysis (FMEA) methods. First, the hazards in the stainless tank production process were identified. Identified hazards were assessed with the FMEA method to calculate Risk Priority Number (RPN) for each hazard. The same hazards were then weighted by using the AHP method. Finally, AHP and FMEA are integrated to achieve a more objective result by using two subjective methods. According to the integrated method results, risks have been prioritized and an objective ranking has been established for action plans.

A construction project fulfills both the product design and the service provision functions. There are many stakeholders in these processes. Concurrence among the stakeholders surely affects the success of the project. The most important of the stakeholders is customer/client followed by architects and civil engineers. Both architects and civil engineers are involved in the design phase as well as in the execution phase. Customer/client satisfaction is usually considered one of the success criteria of the project. This criterion, however, is a subjective concept, about which tangible values cannot be easily placed, and is determined by perception at best. Whether this perception vary between civil engineers and architects depending on different criteria, is examined in this study. The results of the questionnaires were evaluated statistically. The agreed upon and the most important issues are working together and sharing information. The behavior of client/customer and qualification of employees are the factors that civil engineers and architects do not have the same views on client satisfaction.

Irregular urbanization causes problems such as decrease in fertile agricultural areas, irregular industrialization and urbanization. To provide a healthier life opportunity for future generations without disturbing nature, it is essential to determine the temporal changes in land use and to make land management plans accordingly. In this study, land use/land cover (LULC) change occurred in Kahramanmaras province within 30 years was investigated by remote sensing and integration of Geographic Information Systems. Landsat satellite images of 1988-1998-2008-2018 were obtained for the production of LULC maps. Each image was classified according to supervised classification approach using the support vector machines (SVMs) algorithms. The confusion matrix was created for each year to examine the accuracy of the LULC maps. The overall accuracy of the thematic maps was obtained as 91.76%, 93.56%, 86.89% and 88.29%, respectively. Also, Kappa values of thematic maps for each year were obtained as 0.88, 0.91, 0.81 and 0.84, respectively. When the results were examined, the development of industry in the city area and the construction of the airport contributed to the development of the social and economic structure of the city. The increase in the number of housing in the related regions has led to an increase in the amount of urban areas and a decrease in agricultural areas.
