In this study, combined thermal radiation and natural convection heat transfer problem are investigated in glass and plastic covered flat solar collector. The bottom plate that absorbs the sunlight and the ambient temperature are kept constant. Solar collector…

Carbides change highly effective on the mechanical and tribological properties of the coatings. For this reason, it is very important to determine the carbide ratio in the microstructure correctly. Researchers mostly try to determine phase ratios by optical im…

Structural health monitoring allows the status of structures or components to be assessed using sensors. This method is widely used in the evaluation of the state of engineering structures, especially aviation and space engineering. Sensors used in structural …

Energy is at the forefront of the needs to maintain the continuity of life and make it easier, and the energy demand is increasingly dependent on population growth. Today, fossil energy resources are widely used to meet energy demand and renewable energy resou…

Over the years, developments in the world of science and technology have emerged. Developments in image classification methods can also be evaluated in this context. Nowadays, the use of image classification methods for extracting information from data obtaine…

Size of damage caused by an earthquake depends on the amount of energy released by the current stress accumulation of the active faults and the change over time. Stress accumulation on a fault occurs in two types. These are 1) the long-term tectonic movements …

Electrochromic polymers are conjugated systems that have an ability to change their colors upon applied potential. These systems are potential candidates in various technological applications such as organic solar cells, light emitting diodes, smart displays a…

In this study, dependency structure of order statistics which are widely used in statistical hypothesis, prediction problems, statistical process controls, reliability, risk management and many applied areas have been investigated with copulas. Dependency rela…

Molecular interactions have been a hot topic in chemistry because of their importance in different processes from biological activities [1]. Quantum dots with strong and easily tunable luminescence and high emission quantum yields have become well-established …

Over the past decade, gold nanoparticles (AuNPs) have stimulated great interest in various types of sensors because they possess many attractive properties such as optical, electronic and chemical features [1]. In order to gain more intrinsic properties and …

Lubricant oils are products designed to form a protective film that reduces wear and friction of machinery moving parts, protect against corrosion, cool surfaces, and reduce energy consumption. During operation, lubricant undergoes chemical changes due to cont…

Developing technology, and electronic devices, power consumption is increasing day by day. At the present time, there are many methods used to generate electricity. Most of these methods cause environmental pollution. The share of thermal power plants in elect…

In today’s world with ever-aggravating environmental problems, environmental training has a great significance in mitigating and coping with such problems. Environmental pollution is the greatest problem today and certain measures and steps should urgently be …

Cementation steels; surface hardness is high and abrasion resistant materials.Also, cementation steels are materials with the alloyed or non-alloyed structure which materials used in the manufacture of parts which are resistant to shock and variable loads.Addi…

Coils are electrical-electronic circuit elements and they are obtained by winding conductive wires on top of one another on a core or space, when electrical current pass through the coils they bring a magnetic field around them. The electromotive force (emf) t…

The capitalist system’s entry of a crisis from the 70s has facilitated the "meta" of education, which first led to changes in the provision of educational services. Presentation of the education service at a price does not mean that the education is used for t…

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…

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…

Today tourism has made significant progress that an important source of income for countries and the development of international trade.with the increasing tendency of travel in line with the rising standard of living individuals. Tourist product perceptions a…

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…
