Childhood is a sensitive period in which human life is shaped and the environment in which the child interacts is of great importance. Since the child has a constantly evolving and changing structure, its furniture needs to be changed in terms of both functi…
Bu çalışmanın amacı, dünyada ilk 10’a giren ve hisse değerlerine ulaşılabilen düzenli hat taşımacılığı yapan 8 şirketin hisse değerlerinde etkin piyasa hipotezinin geçerli olup olmadığının tespit edilmesidir. Bu doğrultuda, zayıf formda etkin piyasa hipotezi…
The successful estimation of future electricity consumption has a crucial importance in the energy planning. Because, in order to meet rising energy demand, policy makers should formulate electricity supply policies and make critical decisions and develop ne…
In the fifth generation (5G), the traditional restrictions that limit the capacity of wireless communication must be overcome. Non-orthogonal multiple access (NOMA) is a promising solution capable of overcoming these constraints to meet the requirements of 5…
The industrial–style designs affecting today’s perception of designs in a huge velocity has emerged first by the industrial revolution. Although being time–dependent and taking longer time and economically highcost product, the handcraft has allowed the indus…
Because of the great earthquakes that have occured for centuries, many loss of lifes and goods have been experienced all over the world. Our country is located on active seismic zone. Many great earthquakes have also occurred in our country and have caused man…
Variable magnetic fields are widely used in energy production. Two methods can be applied to make the magnetic field variable. The first of these is to apply an alternating current to the insulated conductor on the outer surface of a core. The other is to rota…
Together with rapid growth in population, industrialization and urbanization, environmental problems are also growing. Increasing human pressure on environment and resultant ecological destructions then come to the front as significant problems. At the end, it…
We are at a time when electronic systems are structured in a manner similar to the human brain.The memristor, a neuromorphic circuit designed by Chua in 1971, is a modeling of synaptic learning and associative learning. Neuromorphic circuit elements and memris…
The log files that are continuously recorded are one of the most important information generated by web servers.Hadoop is an open source application platform that works on large amounts of data using hardware clusters. Web server logs are large-volume plain …
Text mining, which aims to derive unknown and useful information from available textual data, is one of the subfield of data mining. Text mining transforms unstructured textual data into structured form by utilizing various methods. Data mining techniques ca…
Nowadays, as the population increase, various construction projects are made on soils which engineering properties are not suitable. Many stabilization methods are used in order to prevent deformations and loss of bearing capacity on such soils. However, most …
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…
Many situations in human life are described with uncertain narratives. The fuzzy set theory has revealed as a powerful tool to deal with the uncertainty of human thoughts and expressions, by Azerbaijani Prof. Dr. Lotfi A. Zadeh in 1965. In the classical cluste…
