Taşıtların elektrik ihtiyacı taşıtın cinsine göre her geçen gün artarak devam etmektedir. Bu ihtiyacı karşılamak taşıtlarda bulunan geleneksel elektrik üretim ve depolama yöntemi dışında egzoz ısının geri kazanımı, güneş enerjisi uygulamaları yanı sıra süspa…
Tek Fazlı Şebeke Kalkışlı Sabit Mıknatıslı Senkron motorlar (TF-ŞKSM) günümüz endüstrisinde kullanılan standart indüksiyon motorlarına göre özellikle küçük boyutlarda daha yüksek verimlilik sunabilmektedirler. Verimliliğin artması çevre üzerindeki olumsuz et…
In the last century, there has been an ever-increasing demand for novel materials namely known as composites. Biological fibers are reinforcement materials of composite structures owing to their economic and ecological advantages. Among these fibers, plant f…
In industrial robots, projected torque is increasing depending on the extending reach length and payload. This requires selection of powerful engines particularly on the second axis. Since arm's rigidity becomes more important as the expected positioning preci…
The aim of this study is to investigate the production conditions of silver nanoparticles in the presence of AgNO3 with the cytoplasmic fluid of white rot fungi Coriolus versicolor. In the study, parameters such as pH, AgNO3 concentration and cytoplasmic fluid…
Plastic injection molding is a manufacturing process of heating plastic granules and forcing melted plastic into a mold cavity and removing from the mold after cooling. One of the most important elements in the production of parts by plastic injection molding …
In this article, the influence of the use of three different bricks on the building heat performance is compared for use on wall surfaces as a building construction element. At the beginning of the analysis, the thermal analysis of the building was carried out…
In this paper, a thermal insulation analysis was carried out for a building using paper waste reinforced clay brick as building material. Firstly, the analysis was made using two different normal wall bricks as building material for the sample building. Later,…
Fins are basic structures which can be easily added to many engineering designs to improve heat transfer from hot surfaces. The addition of a fin to a particular heated surface can significantly increase the cooling at no extra cost. In some cases, standard fi…
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…
High temperature superconductors (HTSs) have been widely used in magnetic bearing systems, magnetically levitated transportation systems (Maglev), superconducting motors, etc. due to their stable levitation properties. Although the studies on Maglev systems ha…
One of the fastest 3D data acquisition methods is LiDAR scanning technology. By using LiDAR scanners, 3D point clouds of the scanned seen is obtained easily. Although the scanning phase is fast, the meaningful and effective 3D visualization of the scene requir…
Decision making is a mental process in which one of the different options is chosen. All decision-making processes end with a decision. In this thesis, site selection for a new project was examined. Investments requiring very high budgets, such as the construc…
A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessa…
Anti-thyroid drugs are relatively simple molecules known as thionamides, which contain a sulfhydryl group and a thiourea moiety within a heterocyclic structure [1]. Methimazole (1-methyl-2-mercaptoimidazole) is widely used drug in medicine for treatment of hyp…
In recent years, with the change of precipitation regimes, the value of water has become important for water sources, especially surface flow and streams fed by the source. Considering this importance, quantitative values; Considering that Turkey's water probl…
Before planning in urban and rural areas, it is necessary to determine the most suitable land use criteria. If these criteria are not kept in sight, inappropriate use will occur and many problems ascertain. In this context, the recreation areas within the rura…
İnşaat sözleşme yönetimi, sözleşmelerdeki şart ve koşulları müzakere etmeyi ve hüküm ve koşullara uyumu sağlamayı, ayrıca uygulama veya yürütme sırasında ortaya çıkabilecek herhangi bir değişiklik veya düzeltmeyi belgelemeyi ve kabul etmeyi içerir. Sözleme yön…
The hot-injection is one of the most used chemical synthesis methods to be able to produce nano- and/or micron sized particles in a liquid medium. Synthesis of nanoparticles of group II-VI semiconductors such as ZnO, ZnSe, CdSe and IV and V metals such as Pb…
