Bu çalışmada, DIN 1.2738 çeliği CVD kaplı karbür kesici takımlarla kuru kesme şartlarında tornalama deneylerine tabi tutulmuştur. Kesme parametreleri; üç farklı kesme hızı (150, 200, 250 m/dak), üç farklı ilerleme hızı (0,1, 0,15, 0,20 mm/dev) ve sabit kesme…
Hardox çelikler mükemmel aşınma direncine sahip, ultra yüksek mukavemetli, kayma ve darbe aşınmasına karşı dayanıklı martensitik çeliklerdir. Madencilik ve inşaat mühendisliği endüstrisinde ağır makineler ana uygulama alanıdır. Bu çalışmada, Hardox 400 çeliğ…
Structural health monitoring is an interdisciplinary field that it is possible to identify defects in the structure or components of the structure at an early stage. The sensors used in structural health monitoring are called the piezoelectric wafer active sen…
Wireless Sensor Networks, used widely nowadays, are likely to be unprotected against a variety of external attacks because they are often used in outdoor applications. Protecting the network against attack and ensuring the safety of the data has always been im…
In the analysis of the flood routing problem, it is necessary to determine the change of the flood wave moving through the channel according to time and location, and in this context, nonlinear 3-parameter Muskingum model (NL-MUSK) is widely used. The parame…
Bu çalışmada Yapay Arı Koloni optimizasyon algoritmalarının üç varyantı sürü robotların hedef bulma probleminde kullanılmıştır. Yapay arı kolonisi optimizasyon algoritmalarının Unity 3D ortamında simülasyonunu gerçekleştiren yazılım geliştirilmiştir. Sürü ro…
Optimal operation of the power systems is very important. In this paper, a new approach for both the economic active power flow and active power loss minimization in multi-terminal HVDC systems is proposed. In the proposed optimization approach, system constra…
As the world is running out of fossil fuels and the environment is being seriously damaged by the combustion residuals of the internal combustion engines, the world countries have begun to search alternative ways for mobility. Lightweight electric vehicles w…
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…
Optimal reactive power flow and economic power dispatch is very important in power systems. Optimal reactive power flow provides minimum active power loss and economic power dispatch provides minimum active power generation cost in power systems. This study pr…

In this paper, a different approach for the optimal active power flow solution in multi-terminal HVDC systems to minimize total active power generation cost is proposed. System constraints for all of the control and state variables of both AC and DC systems ar…
Experimental design methods used in optimization of engineering problems and processes in many industrial fields have been shown to be applicable in road superstructures within this study. Using the special purpose statistical experiment design program, opti…
Renewable energy can be produced by using kinetic energy of the flowing water such as rivers, ocean currents and tidal flows. The kinetic energy can be transformed to the power by hydrokinetic turbines. There are many different designs of hydrokinetic turbin…
Soft wheat flour is the most important raw material in the production of cookies. But because of gluten intolerance of celiac patients they should not consume gluten containing cookies made from wheat flour. Therefore in this study it was aimed to form a suita…
A useful and flexible method based on the salp swarm algorithm (SSA) for the pattern nulling of linear antenna arrays with the prescribed nulls is presented. SSA is a relatively new population based evolutionary optimization algorithm. Nulling of the pattern i…
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…
