Taşıyıcı sistemlerin deprem, rüzgar gibi etkiler altında dinamik analizinde serbest titreşim analizi önemli bir yer tutmaktadır. Dinamik yükler altında taşıyıcı sistemlerin serbest titreşim analizi sürekli veya ayrık kütleli hesap modelleri kullanılarak gerç…
In this study, the effect of using a mixture of butanol and diesel fuel in a small diesel engine on engine performance and exhaust emissions is modeled. A comparison has been made with artificial neural networks, which is an up-to-date method, and multiple l…
Energy demand in the 21st century is increasing continually. This increase in energy demand is one of the factors affecting the increase in universal problems. Energy is produced using both renewable and non-renewable resources. Therefore, energy consumption…
Recently, it is inevitable to use numerical analysis methods for several geotechnical engineering problems solution due to the complexity of behavior characteristics of soil medium. In this study, numerical analysis methods that are used to obtain numerical …
Evaluation of rock engineering properties is a significant phenomenon for mining, civil and geotechnical engineering disciplines. Uniaxial compressive strength is one of the most important engineering parameters and it is used to characterize rocks from the …
Pansharpening, which is transferring the spatial content of a high-resolution panchromatic (PAN) band into a lowerresolution multispectral (MS) image to produce a spatially enhanced MS image, has always been one of the hottest topics of image processing. Nume…
İlk olarak 1999 yılında RFID teknolojisinin kullanımının önerildiği bir sunumda kullanılan Nesnelerin İnterneti kavramı (IoT); cihazların kendi aralarında konuştuğu (veri iletişimi yaptığı, bilgi topladığı, toplanan bilgiler ile karar verdiği) bir ağ yapısı …
This study was compiled from the results of various researches performed on using diethyl ether as a fuel or fuel additive in diesel engines. Three different techniques are used the reduction of the harmful exhaust emissions of diesel engines. The first tech…

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…
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…
In this study, the problem of dam break wave propagation over a dry bed in a horizontal rectangular channel was investigated. Dam break event was represented by a sudden removal of the plate which has water on the upstream side. The experiment was recorded b…
Trend analysis of precipitation play a significant role in the efficient water resources management, especially in arid and semi-arid regions. In this study, 48 years-long (1970-2017) annual precipitation data monitored at nine selected stations (Mardin, Adı…
Density functional theory (DFT) is a computational quantum mechanical modelling method used in physics, chemistry and materials science to investigate the electronic structure (principally the ground state) of many-body systems, in particular atoms, molecule…
Additive manufacturing which is developed in the last half century is promising manufacturing technology. It uses layer-wise production method for obtaining finished product. In recent years, thousand researches were made but there was still gaps about impac…
TiO2 films have been deposited by sol gel spin coating technique onto glass and p-Si substrates. TiO2 films were prepared using two different sols. The physical properties of the TiO2 films were examined based on two different parameters. In the first study,…
In this study, hybrid composite structures were manufactured by vacuum assisted resin transfer molding method using three different woven fabrics (jute, E-glass and carbon) as the reinforcing material and polyester resin as the matrix material. All composite…
