Climate change and environmental concerns led the investors to search for environmentally sustainable and friendly investments. Green bonds market has emerged as a result of this need. This study aims to analyze this market focusing on market efficiency. Marke…

Developing technology in the manufacturing industry and the requirement of high precision parts reveals micro machining. It is possible to produce workpieces both at high speed and with high precision by means of micro-mechanical machining.The finite element m…

In order to investigate the relationship between variables, it is necessary to reveal the dependency structure between variables and because of this reason, the concept of “copula” is being used in statistics literature in recent years. The main purpose of the…

Ergonomics is the process of designing or arranging workplaces, products and systems so that they fit the people who use them. Ergonomics is a branch of science that aims to learn about human abilities and limitations, and then apply this learning to improve p…

Scheduling is the allocation of resources to tasks (eg. machines to jobs) in order to ensure the completion of these tasks in a reasonable amount of time. Fuzzy logic is applied to the scheduling problems for the cases where the time parameters like processing…

Jeotermal enerji varlığını dünyanın kuruluşundan bu yana sürdürmüş temiz bir enerji türüdür. Her geçen yıl yeni jeotermal alanlar bulunmakta ve kullanım alanları hızla artmaktadır. Enerji maliyetlerinin yükselme eğiliminde olduğu günümüzde jeotermal enerji alt…

The structure of the gas diffusion layer influences cell performance because it also affects the passage of reaction gases and electrons. In this study, the effect of the thickness of the gas diffusion layer on the cell performance for the singlecelled PEM fue…

3D printing filling structures at prototyping and design stage are increasingly important issue for products with complicated shapes. The objective of the present study is to investigate 3D printing filling structures effect on mechanical properties and surfac…

Exhaust gas distribution in street canyons is one of the important research subjects in urban air quality studies. Vehicle emissions are an important group of pollutants in urban areas. In this study, the dispersion of exhaust emissions from vehicles in canyon…

Refrigeration and air-conditioning systems consume about 15% of global electricity, and 46% of energy used in household and commercial buildings belongs to heating, ventilation and air-conditioning (HVAC) systems. Vapor-compression technologies dominate the HV…

The use of GPUs for general purpose applications is not a recent approach, but it was quickly becoming widespread with NVIDIA's CUDA (Compute Unified Device Architecture) architecture based on C programming language in 2007. Algorithms suitable for parallel op…

In the present study, the effects of cutting parameters on surface roughness were investigated in order to determine the optimum machining conditions for the hot work tool steel (155 HB), which is an important part of the mold industry. For this purpose, the m…
