Lower limb exoskeletons are wearable robotic devices which either augment human power or facilitate a walking ability for those who lost it by injury or aging. They have been getting more and more attention in the scientific community thanks to its increasin…

Maxwell denkleminin AV formülasyonu esas alınarak, zamana bağlı bir akım altında süperiletken telin elektromanyetik özelliklerini çözmek için yeni bir sayısal model geliştirilmiştir. Farklı akım genlikleri için alternatif akım (AA) kayıpları hesaplanmış ve iki…

Recently, it is inevitable to use numerical analysis methods for several geotechnical engineering problems solution due to the complexity of behavior characteristics of soil medium. In this study, numerical analysis methods that are used to obtain numerical …

An analysis of mechanical stresses under an external AC magnetic field in a coil stack was performed using the finite element method solving "mechanical equilibrium equation" by Comsol Multihysics finite element software. A-V formulation has been used for the …

This study presents the modelling of the pathological elements based memelements. More than forty years ago, Chua predicted the existence of memristor (memory+resistor) which is the fourth fundamental passive circuit element. In 2008, Hewlett Packard (HP) rese…

Nowadays, in the field of industry and commerce, heavy loads have to be removed by various methods and moved from one place to another. Mobile cranes in order to overcome these tasks are in common use. One of the problems that prevent the safe and long-lasting…

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 this study, the problem of dam break wave propagation over a dry bed in a horizontal rectangular channel was investigated. Dam break event was represented by a sudden removal of the plate which has water on the upstream side. The experiment was recorded b…

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…

Because of the great earthquakes that have occured for centuries, many loss of lifes and goods have been experienced all over the world. Our country is located on active seismic zone. Many great earthquakes have also occurred in our country and have caused man…

Günümüzde, endüstri ve ticaret alanında, ağır yüklerin çeşitli yöntemlerle kaldırılıp bir yerden başka bir yere taşınması gerekir. Bu işlerin üstesinden gelme amacıyla mobil vinçler yaygın kullanıma sahiptir. Mobil vinçlerin güvenli ve uzun ömürlü çalışmasını …

Boundary-value problems with eigenparameter dependent boundary conditions is one of the most extensively developing fields in pure and applied mathematics. First, we cite the works of Walter and Fulton, both of which have extensively bibliographies, a discus…

Bu çalışmada plastik malzemeler üzerine yapılan metalik kaplamalar incelenmiştir. Metalik kaplamalarda katman kalınlığıyla ilişkili olarak termal yük altında termal genleşme sebebiyle oluşan gerilme dağılımları araştırılmıştır. Çalışmada silindir çubuk, kiri…

One of the major problems encountered designers working in the developing industry is how product can get better designs in the first stages. There are many structural optimization methods for weight reduction operations. One of them is the lattice structura…

The dams built for the purposes of electricity generation, domestic and irrigation water supply, flood control, etc., make a great contribution to the region and country's economy. For all these purposes, dam construction is very difficult and costly. In addit…

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 …

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…

Meriç River is the longest river ecosystem of the Balkans and most lotic ecosystem in Thrace Region of Turkey. Tunca River is one of the most important tributary of Meriç River. Therefore it is significantly effective on the water quality of Meriç River. In …

In this study water samples were collected from 30 villages located in the Ergene River Basin in summer season of 2018. Nitrate (NO3) and nitrite (NO2) concentrations of water samples were determined and the results were assessed according to national and in…

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…
