Although numerous amounts of research have been done to find alternate sources of energy consumption and its applications. But in times of energy crisis and global warming urgency, it is needed to pace towards methods of less dependency on fossil fuels in the …

In this study, we focused on to drive a compound DC motor with a Fuel-Cell and battery, which uses hydrogen as a fuel. A fuel cell can supply maximum 40V electric. In order to drive a DC motor, it needs 200Vdc. Therefore, a microcontroller controlled boost con…

Fossil fuels used by traditional internal combustion vehicles today are quite damaging to environment. Because of these fuels, global warming has reached a very dangerous point. However, fossil fuels are gradually depleting. Therefore, it is inevitable that el…

In this study, the experimental application of polymer electrolyte membrane fuel cell (PEM-FC) with dc-dc boost converter is realized for compact design of electric vehicle (eV). The PEM-FC is an electro-chemical device which combines hydrogen with oxygen to p…

This study examines the effects of inrush current loads on electric motors operating under low-temperature conditions. While electric motors have a wide range of applications in industrial and military environments, they face significant performance challenges…

Developing technology, and electronic devices, power consumption is increasing day by day. At the present time, there are many methods used to generate electricity. Most of these methods cause environmental pollution. The share of thermal power plants in elect…

A theoretical design assessment performed here to evaluate the idea of utilizing wave energy in the Red sea to power electric-cargo ships, in the route between Port Sudan and Jeddah Islamic port. The calculated mean wave power in 2018 was (1.4 MW), five wave p…

In this work, the effect of Ti addition (0, 1, 3, 5, 7, 10 wt%) on the electrochemical properties of Al-25Si alloys fabricated by melt spinning was investigated. Preparation of anode materials, the spinned types were powdered by cryomilling. The electrochemica…

Tüm dünyada özellikle de kent merkezlerinde yaşayan insan nüfusu her geçen gün artmaktadır. Nüfus artışına bağlı olarak sosyal, ekonomik ve çevre sorunlarını da her geçen gün artmaktadır. Günümüzde kent merkezlerinde görülen en önemli çevre sorunlarından biri …

In this study, combined thermal radiation and natural convection heat transfer problem are investigated in glass and plastic covered flat solar collector. The bottom plate that absorbs the sunlight and the ambient temperature are kept constant. Solar collector…

Urban areas have less vegetation than natural environment that surround it. Differences between these types of areas affect climate, energy use, and habitat in cities. In urban areas, dark surfaces and reduced vegetation warm affect the air over urban areas, l…

Increasing number of motor vehicles together with economic development brings serious air pollution problems. Especially, Particle Matter emissions from Internal Combustion Engines are difficult to control and highly dangerous for human health. Both Europa and…

In last years, the use of alternative energy sources such as solar energy has become even more important because of environmental problems, especially the rapid depletion of fossil energy resources. There are works done for this purpose and solar energy applic…

The effects of climate change in the world are observed to have significant effects on different environmental variables. Therefore, changes in climate parameters should be examined and analyzed. These changes can be determined by parametric and non-parametr…

This study examines the failure mechanisms of a three-phase AC induction electric motor with a closed body design, intended to provide IP protection, due to insufficient cooling under high-temperature conditions. Overheating at elevated temperatures adversely …

This paper presents the theoretical aspect of the creep behavior in materials, particularly in metallic materials. Different creep mechanisms were displayed. The main models developed to determine or extrapolate the rupture time of materials were presented. So…

One of the significant factors that should be examined when performing a thermoluminescence (TL) study related to a natural material is the detection of the trap depth. The various heating rate (VHR) method is one of the practical methods used in the calculati…

Courtyards hold significant functional value in both traditional and contemporary architecture. They serve as open-air spaces that facilitate social interaction for users within urban environments. In order for these spaces to be utilized more efficiently by u…

Structural health monitoring is an interdisciplinary field that it is possible to identify defects in the structure or components of the structure at an early stage. The sensors used in structural health monitoring are called the piezoelectric wafer active sen…

Today, with the rapidly development of technology, artificial neural networks (ANN) usage as an alternative to statistical methods increase in many fields such as finance sector, medical science, defense industry, production, robot systems, image processing an…
