In this work, the influence of the amplitude for four frequencies and directions of the applied field on the AC loss of an HTS pancake coil is extensively investigated by the finite element method in COMSOL Multiphysics software with an AC/DC module. The numbe…

Bitumen polymer modification has a long history. However, most of the polymers currently used as additive in bitumen are not economically attractive. Thus, employing recycled materials in flexible highway instead of virgin ones has become a fundamental case …

Various deteriorations primarily rutting occurs in hot mix asphalt under conditions of traffic, climate and environmental in length of time. To increase the resistance of mixtures and thus delaying these deteriorations, the various additives are added to the b…

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…

Today, university campuses are important living spaces with their versatile functions in terms of recreational, social, ecological and economical aspects as well as educational and scientific studies. Recreational activities have an important place in the life…

Interest in Data Envelopment Analysis (DEA) has grown in recent years. This is not surprising since DEA can be used to explore efficiency in organizations whose outputs and inputs cannot be reduce to monetary terms. In a relatively short period of time Data En…

It is aimed to analyze the layout of eight baths, which have survived from the Menteşeoğulları Principality period to the present day, by means of rule based analysis. In addition, in this study, it is examined how space fiction, Inter-space relationship and…

DC-DC boost converters are usually used so as to increase voltage in battery charging of electrical vehicles, power factor correction circuits and solar photo voltaic panels etc. applications. The control of these converter types is realized with Pulse Width M…

Multiple imputation (MI) is increasingly being used as a sophisticated tool to handle missing data in the recent years. The standard MI techniques use Bayesian sampling methods for making posterior draws for the imputations and analyse the imputed data sets un…

Cooling process applied to complete sintering cycle of aluminum composites produced by hot pressing method has a great effect on grain size, hardness and wear resistance. In order to obtain a fine-grained microstructure, increase hardness and reduce amount of …

Numerous studies have been carried out in the field of material science for the development of lightweight materials with high wear resistance, high strength and good corrosion resistance. Aluminum and its alloys are one of the most important engineering mater…

Günümüzde, endüstri ve ticaret alanında, ağır yüklerin çeşitli yöntemlerle kaldırılıp bir yerden başka bir yere taşınması gerekir. Bu işlerin üstesinden gelme amacıyla mobil vinçler yaygın kullanıma sahiptir. Mobil vinçlerin güvenli ve uzun ömürlü çalışmasını …

In this study, mixed convection heat transfer and fluid flow in a three-dimensional horizontal duct with three different geometries of cavity were investigated numerically. Air flows in a square duct which is heated by a cavity with triangular, a rectangular a…

Wireless Sensor Networks, used widely nowadays, are likely to be unprotected against a variety of external attacks because they are often used in outdoor applications. Protecting the network against attack and ensuring the safety of the data has always been im…
