Analog filters have an important role in modern communication systems. Filter circuits with low noise, which occupy less chip area and consume less power as well as operate in the high-frequency region, are required with the developing technology. In the liter…
In this work, the effect of Ti addition (0, 1, 3, 5, 7, 10 wt%) on the electrochemical properties of Al-25Si alloys fabricated by melt spinning was investigated. Preparation of anode materials, the spinned types were powdered by cryomilling. The electrochemica…
The major part of freight transportation in Turkey is conducted by highway, the increase in the number of trucks and other heavy vehicles, as well as legislations allowing an increase in axle load that lead to deterioration such as rutting in flexible road pav…
As widely known, construction on soft soils is generally problematic since the engineering properties of soft soils generally cannot meet the conditions required. Settlement, bearing capacity and seismic performance of the overlying structures is always questi…
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…
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…
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…
Increasing number of motor vehicles together with economic development brings serious air pollution problems. Especially, Particle Matter emissions from Internal Combustion Engines are difficult to control and highly dangerous for human health. Both Europa and…
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…
In this study, thermodynamic analysis of a geothermal power-based district energy conversion system which produces electricity, hot water, heating and cooling are investigated. The energy produced from geothermal resource can be utilized to drive a double stag…
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…
Bilişsel radyo kullanılmayan ya da az kullanılan spektrum bantlarına dinamik olarak erişim olanağı sağlayan ve kullanıcılar arasında herhangi bir olumsuzluğa neden olmadan spektrum paylaşımını gerçekleştiren yazılım tabanlı bir teknolojidir. Kablosuz haberleşm…
Nowadays new applications and new web sites are being developed, better methods and tools are needed in order to be able to develop web or mobile applications in a fast and interactive way with minimal code structure. In this point, both the design of the appl…
In this study, AISI 430 ferritic stainless steel sheet with 0.6 mm thickness was joined by resistance spot welding at different welding times and currents. The effects of welding parameters on the mechanical properties of welded samples are defined in terms of…
Nowadays, there are old and new methods that involve the difficult problems and solution suggestions which many researchers research and try to solve. In the field of engineering, the success rates of the methods that produce solutions to these problems are of…
Several test suites have been developed to test the statistical properties of random numbers generated from pseudotrue random number generators. Some of these are Crypt-X, Diehard, FIPS 140, NIST 800-22 AIS31 test suites. In this study, web based application o…
Increasing in wireless communications systems is caused to increase in the need of the frequency spectrum. CR (Cognitive Radio) measure or sense frequency spectrum activities on spectrum bands whether they are idle or used by licensed users. According to sensi…
Aluminum based metal matrix composites are frequently used in automotive, aircraft, space, automotive, agricultural and building industries due to their easy shaping, good heat and electrical conductivity, low density, high strength and toughness. In these com…
Nowadays, competition in industrial production has come to the top with technological improvements. In this competitive environment, producers need better quality, faster and less costly production methods. So, the use of industrial robotic systems is becoming…
