The purpose of this study is to assess the secondary school students’ expectations regarding the daily use of technology on part of their parents and teachers. The sample used in the study organized around the case study model was composed of 30 students fro…
Bu çalışmada, frekans çözünürlüğünün (yankı çözünürlüğünün) R-MUSIC (Root-MUSIC, Çoklu Sinyal Sınıflandırma) ve ESPRIT (Rotasyonel Değişmezlik Tekniği ile İşaret Parametrelerinin Kestirimi) yöntemleri kullanılarak nasıl değiştiği incelenmiştir. Bu yöntemler,…
In this talk, we work on a model of the prey-predator system to see the effect of system components on species distribution for both temporal and spatial structure. In some cases, changing environmental conditions results in extinction or leads the survival …
Fuel cells can be considered as clean, efficient and economic devices for the next power generation. Flow configuration and operating conditions such as temperature, relative humidity and stoichiometric number are key factors for improving cell performance. …
Bu araştırmanın amacı Samsun İlindeki bir devlet lisesindeki öğrencilerin, internet bağımlılığını ölçmek ve bu durumun depresyon üzerindeki etkilerini belirlemektir. Çalışmada lise öğrencilerinin demografik özellikleri ile birlikte internet bağımlılığı ve de…
In this paper, a different approach for the optimal active power flow solution in multi-terminal HVDC systems to minimize total active power generation cost is proposed. System constraints for all of the control and state variables of both AC and DC systems ar…
This paper presents a different approach for the optimal active power flow solution in multi-terminal AC-DC systems to minimize total active power generation cost. System constraints for all of the control and state variables of both AC and DC systems are also…
The dams built for the purposes of electricity generation, domestic and irrigation water supply, flood control, etc., make a great contribution to the region and country's economy. For all these purposes, dam construction is very difficult and costly. In addit…
Today, rapid population growth and the development of technology have brought about the problem of waste. In order to solve this problem, it is first necessary to reduce the waste generation at the source. This can be achieved by raising awareness of the consu…
Asynchronous motors are the most preferred engines in the industry due to factors such as their stable speed, economic and operational safety. Recently, asynchronous motors have been used as generators in the power generation sector and especially in wind turb…
Analog filters have an important role in modern communication systems. Filter circuits with low noise, which occupy less chip area and consume less power as well as operate in the high-frequency region, are required with the developing technology. In the liter…
Today, it is possible to access a lot of information by using medical imaging data (CT and MR). In recent years, CT and MR data have been processed and transferred to computer aided design (CAD) programs. In fact, these solid models modified in the CAD environ…
In this study, an experimental investigation of electricity production from a thermoelectric cooler heated by solar energy heat pipe has been done. For this, a heat pipe with water as the working fluid has been manufactured. Approximately 300 ml of water stora…
The aim of this study is to determine instantaneous irradiance and annual percentile sunlit time on the available rooftop floor area of Technical and Social Science Vocational School at Usak University by simulation using open source software. The building of …
Grinding of brittle material such as glass is becoming crucial in consequence of rapid growth in the area of white goods. Industrial area, during flat glass processing iron based diamond wheels can be selected in order to improve the service life of the grindi…
The rapid growth of cities causes spatial and social changes and transformations. At the same time, planning theories and concepts are affected by change processes. While the search for innovative methods in urban development and applications comes to the fo…
It is clear that the anthropologists launched by Edward B. Tylor in the classical religionswissenschaft period, having continued on the evolutionary line - for instance those of Robert R. Marett, George Frazer - with terms such as anxiety, devotion, fear, depr…
The contribution focuses on the trend that is developing with increasing prominence in contemporary architecture towards the use of materials and technologies from sectors other than the specific field of construction. This phenomenon has also characterized th…
Copulas are the special functions obtained with a combination of functions. Therefore, appropriate conversions can be made to create new copulas or to improve the existing copulas. Many researchers have recently aimed to obtain variables with higher correlatio…
