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. …

The study aims to analyze the views the teachers, who attended the training on study sheet preparation using interactive web apps, have about the process. The sample used for case study contains 26 teachers who attended the “Study Sheet Preparation Using Int…

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 …

A novel continues plasma reactor with rotating electrodes was designed and constructed to investigate methane decomposition to hydrogen and solid carbon. This new reactor structure causes stable operation. Hydrogen is main part of gaseous products which cont…

In the fifth generation (5G), the traditional restrictions that limit the capacity of wireless communication must be overcome. Non-orthogonal multiple access (NOMA) is a promising solution capable of overcoming these constraints to meet the requirements of 5…

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…

Bir işletmenin katma değer yaratan faaliyetlerinin yaklaşık yarısı, araştırma, yenilik, verimlilik, istihdam yaratma, ithalat ve ihracat gibi kavramlarda anahtar rol oynamaktadır. Dolayısıyla İşletmelerin küresel rekabette varlığını sürdürebilmesi, endüstris…

Renewable energy can be produced by using kinetic energy of the flowing water such as rivers, ocean currents and tidal flows. The kinetic energy can be transformed to the power by hydrokinetic turbines. There are many different designs of hydrokinetic turbin…

As the world is running out of fossil fuels and the environment is being seriously damaged by the combustion residuals of the internal combustion engines, the world countries have begun to search alternative ways for mobility. Lightweight electric vehicles w…

The majority of the resources used in the production of electricity in our country are imported. In order to meet the ever-increasing need for energy, it has started to turn to different and new generation energy sources. In this context, especially the use of…

The collective system, which includes the automation system, data exchanges and production technologies is referred to as Industry 4.0. This system has two main components. The first is the new generation of software and hardware, and the second is the cyber p…

The fact that cannot be avoided the non-renewable energy sources (fossil and underground resources) are rapidly depleting, makes the search for new sources of energy extremely important in our country and all over the world. Besides, from past to present, due …

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…

Oscillators are one of the most important basic circuit blocks frequently used in electrical-electronics engineering applications. Among several types of the sinusoidal oscillators, quadrature oscillators are frequently used in communication circuits, control …

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…
