This paper presents a different approach for the optimal active power flow solution in multi-terminal AC-DC systems to minimize total active power generation cost. System constraints for all of the control and state variables of both AC and DC systems are also…

The rapid increase in the world population and climate change due to industrialization require the preservation and sustainability of existing water resources. The calculation of drainage networks that are directly related to watershed management is very impor…

The study presents the tribological behavior of epoxy matrix composites containing two different fillers. Hybrid composites were produced with casting method. The composites contains fillers with different particle sizes (<90µm and in the range of 150-300 µm) …

Boron is a important element that can be used in many different fields such as the ceramic industry, fertilizers, insecticides, corrosion inhibitors and etc. Boric acid is a naturally occurring compound containing boron, oxygen and hydrogen (H3BO3) elements. I…

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…

In this study, we aimed to investigate the effect of the anxiety on blood pressure and heart rate in periexam period. For this purpose, 83 paramedic first class students (19.2±1.0 year old) were included. The blood pressure and heart rate were measured in the …

In order to evaluate different modeling techniques for Unglazed Transpired Collectors (UTC), not only mathematical modeling method for UTC based on heat transfer expressions to estimate the various heat transfer coefficients for the UTC components and empirica…

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…

The use of alternative energy sources has begun to increase with the ever-increasing demand for energy. Today, with this increase, energy production is being tried to be obtained from alternative energy sources. Many companies have included the installation of…
