The integration of increasing renewable energy-based energy production into the existing electricity grid has become of great importance. The biggest difficulty to integration into the power grid is variability and discontinuity of wind energy. To deal with th…
The study of nonlinear boundary value problems is a very important and difficult area of research in differential equations. The aim of our work is to establish the existence of solutions for a second order boundary value problem which models different real si…
In this research, the studies of management and organization in the books of National Tourism Congresses between 2009 and 2017 were evaluated within the scope of several parameters. In this context, the purpose of this research is to analyze published papers a…
This study aims to examine the relationship between employees' organizational commitment and happiness levels. Organizational commitment means that members of the organization strongly believe in and accept the organization's goals and objectives, to be willin…
The aim of this study is to determine the level of emotional intelligence and emotional intelligence levels that university students have. The concept of emotional intelligence was first revealed by Mayer and Salovey. Researchers describe emotional intelligenc…
Infill walls in reinforced concrete buildings produce a strong effect on the strength and deformation capacity of the buildings. In practice, a partial or full absence of infill walls at the first stories may become one of the reasons for vertical irregularity…
The construction sector aims to produce efficient projects by optimizing cost, quality and time. However, this is not always very easy. Projects may not be completed on time, budget may be exceeded or products may not be produced sufficiently high quality. For…
An analysis of mechanical stresses under an external AC magnetic field in a coil stack was performed using the finite element method solving "mechanical equilibrium equation" by Comsol Multihysics finite element software. A-V formulation has been used for the …
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…
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…
With today's developing technology, learning applications reach more people within shorter time. This development of technology closely affects mobile technology. These developments in mobile technology are applied to make learning more effective. Mobile learn…
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…
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 …
