Analysis of faults in synchronous generators are so important to protect the generators and the power systems. In this paper, double line-to-ground fault analysis in unloaded synchronous generator is presented. Apart from the similar studies in the literature,…

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…

In this study, the effect of still water cooling on electricity generation in a thermoelectric generator heated by solar energy heat pipe is experimentally investigated. For this purpose, a heat pipe with ethyl alcohol as the working fluid has been manufacture…

Görme engellilerin yaşamlarını kolaylaştıran teknolojik gelişmeler her geçen gün artmaktadır. Cisimlerin renklerini algılama onların sesle bildirimde bulunulması ile olabilmektedir. Bu çalışmada optik tabanlı renk sensörü tasarlanarak bu renkleri, renk kelimel…

The paper aims is to highlight the unavoidable changes in industrial society together with the basic elements of this transformation as well as to take the attention of the readers on the healthiest change process. Some actions which are considered to be very …

Nowadays new applications and new web sites are being developed, better methods and tools are needed in order to be able to develop web or mobile applications in a fast and interactive way with minimal code structure. In this point, both the design of the appl…

In this study, 0-12wt.% of Si3N4 or 0-30wt.% of SiC was added to the aluminum matrix by powder metallurgy method. Hence, the effect of reinforcement elements’s (SiC or Si3N4) amount on the mechanical properties was examined. Micro structures and crystal struct…

The structure of the gas diffusion layer influences cell performance because it also affects the passage of reaction gases and electrons. In this study, the effect of the thickness of the gas diffusion layer on the cell performance for the singlecelled PEM fue…

Ortodontik tedavi sırasında diş hareketini etkileyen önemli faktörlerden biri sürtünme kuvvetidir. Sürtünme kuvvetine etki eden faktörlere müdahale edilebilirse ortodontik tedavinin süresi ve başarısı ile ilgili olumlu tahminler yapmak mümkün olacaktır. Sürtün…

3D printing filling structures at prototyping and design stage are increasingly important issue for products with complicated shapes. The objective of the present study is to investigate 3D printing filling structures effect on mechanical properties and surfac…

Exhaust gas distribution in street canyons is one of the important research subjects in urban air quality studies. Vehicle emissions are an important group of pollutants in urban areas. In this study, the dispersion of exhaust emissions from vehicles in canyon…

Refrigeration and air-conditioning systems consume about 15% of global electricity, and 46% of energy used in household and commercial buildings belongs to heating, ventilation and air-conditioning (HVAC) systems. Vapor-compression technologies dominate the HV…

The use of GPUs for general purpose applications is not a recent approach, but it was quickly becoming widespread with NVIDIA's CUDA (Compute Unified Device Architecture) architecture based on C programming language in 2007. Algorithms suitable for parallel op…

In the present study, the effects of cutting parameters on surface roughness were investigated in order to determine the optimum machining conditions for the hot work tool steel (155 HB), which is an important part of the mold industry. For this purpose, the m…
