Magnetoresistance Measurements On Electrodeposited Co_X Cu_{1-X} Alloy Films, Ömer F. Bakkaloğlu, İsmai̇l H. Karahan
Magnetoresistance Measurements On Electrodeposited Co_X Cu_{1-X} Alloy Films, Ömer F. Bakkaloğlu, İsmai̇l H. Karahan
Turkish Journal of Physics
Co_x Cu_{1-x} alloy films were prepared by using electrodeposition technique. The variations of Co and Cu contents of the films were investigated as functions of bath pH and Co content. The compositions of the alloy films were determined using an atomic absorption spectrophotometer. The crystal structures of the alloy films were analyzed using a Cu (K \alpha )-X-ray diffractometer. The diffraction lines observed were only those of copper component in the alloy films. All three films showed negative magnetoresistance and a giant magnetoresistance effect on the order of 1% in Co_{0.26} Cu_{0.74} and 1.7% in Co_{0.19} Cu_{0.81} alloy films at …
Multiple Structures Of (110) Csl Twist Boundaries In Fcc Metals, A. Ghafoor, B. A. S. Faridi, S. A. Ahmad
Multiple Structures Of (110) Csl Twist Boundaries In Fcc Metals, A. Ghafoor, B. A. S. Faridi, S. A. Ahmad
Turkish Journal of Physics
The geometry of different possible structures of (110) fcc twist boundaries is explored. Computer simulation of all possible low energy structures have been carried out for \Sigma=3 and \Sigma=9 twist boundaries using many-body potentials representing copper, silver and gold. Low symmetry structures are found to have lower energies than the high symmetry CSL structures.
Properties Of Mos Capacitors Produced On Sige Formed By Ge-Implanted Si, M. Şahi̇n, Serhat Özder, Raşi̇t Turan
Properties Of Mos Capacitors Produced On Sige Formed By Ge-Implanted Si, M. Şahi̇n, Serhat Özder, Raşi̇t Turan
Turkish Journal of Physics
Metal-oxide-semiconductor (MOS) capacitors fabricated on Ge-implanted Si have been investigated by using C-V and G-V measurements. The control sample on pure Si substrate yielded normal C-V and G-V characteristics. The Ge-implanted MOS samples exhibited anomalous C-V and G-V behavior. The C-V curves of the samples were strongly frequency dependent both in the accumulation and inversion regions. They shift almost in parallel to higher values with decreasing frequency, reaching the oxide capacitance value in the quasi-static (QS) measurement. A band structure and equivalent circuit model were introduced to explain this and other features of the experimental observations. It is shown that …
Mössbauer-Effect Study Of Fine Atomic Structure Of Fe-Ni-C Alloys, K. G. Binnatov, A. O. Mekhrabov
Mössbauer-Effect Study Of Fine Atomic Structure Of Fe-Ni-C Alloys, K. G. Binnatov, A. O. Mekhrabov
Turkish Journal of Physics
Fine atomic structure of Fe-Ni-C alloys containing of 30-36 wt. % Ni and 0.1-1.0 wt. % C have been analysed by means of a nuclear \gamma -resonance method. The alloys under investigation were in austenite phase. The study shows that the effective hyperfine magnetic field H_{eff} on the ^{57}Fe nuclei is affected by the presence of C atoms in Fe-Ni alloys and the mean value of H_{eff} fields increase with increasing of C element content in these alloys. It has been detected that increase in carbon content in Fe-Ni alloys leads to a broadening of Mössbauer absorption lines. On the …

An Autecological Study On Iris Histrioides Foster (Iridaceae) Distributed In The Central Black Sea Region, Nezahat Kandemi̇r, Ali̇ Engi̇n
An Autecological Study On Iris Histrioides Foster (Iridaceae) Distributed In The Central Black Sea Region, Nezahat Kandemi̇r, Ali̇ Engi̇n
Turkish Journal of Botany
Iris histrioides Foster, a Euxinian and endemic element, was investigated in terms of its phenological and ecological properties. Some elements taken from the above-and below-ground parts of the plant in the vegetative and generative growth periods have been analyzed. According to the results of the analysis, N%,P% and K% contets are high in above-ground parts during the vegetative growth phase. In addition, soil samples were collected from 0-20 cm depth and analyzed physically and chemically.

Knowledge-Based Navigation For Autonomous Road Vehicles, Murat Eki̇nci̇, Franches W.J.Gibbs, Barry T. Thomas
Knowledge-Based Navigation For Autonomous Road Vehicles, Murat Eki̇nci̇, Franches W.J.Gibbs, Barry T. Thomas
Turkish Journal of Electrical Engineering and Computer Sciences
This paper presents a computer vision system for an autonomous road vehicle (ARV) that is capable of negotiating complex road networks including road junctions in real time. The ultimate aim of the system is to enable the vehicle to drive automatically along a given complex road network whose geometric description is known. This computer vision system includes three main techniques which are necessary for an ARV: a) road following, b) road junction detection, c) manoeuvring at the road junction. The road following algorithm presents a method of executing a number of algorithms using different methods concurrently, fusing their outputs together …
Decentralised H_{\Infty} Load Frequency Controller Design Based On Ssvs, Hasan Çi̇men
Decentralised H_{\Infty} Load Frequency Controller Design Based On Ssvs, Hasan Çi̇men
Turkish Journal of Electrical Engineering and Computer Sciences
The decentralised load-frequency controller design problem concerned is translated into an equivalent problem of decentralised controller design for a multi-area multi-input multi-output (MIMO) control system. It is shown that subject to a condition based on the structured singular values (SSVs), each local area load-frequency controller can be designed independently. The stability condition for the overall system can be stated as to achieve a sufficient interaction margin. It is demonstrated by computer simulation that within this general framework, local H$_{\infty}$ controllers can be designed to achieve satisfactory performances for a sample two-area power system.

Information And Average Information Rates Of A Graphical Access Structure On Six Vertices, Mustafa Atici
Turkish Journal of Electrical Engineering and Computer Sciences
In this paper we study the optimal information and average information rates of secret sharing schemes which are all connected graphs on six vertices. There are $102$ connected graphs on six vertices that are not complete multipartite graphs. Of these $102$ graphs, we determined the optimal information rate of $71$ graphs, and the optimal average information rate of $88$ graphs.
Comparison Of Simulation Algorithms For The Hopfield Neural Network: An Application Of Economic Dispatch, Tankut Yalçinöz, Hali̇s Altun
Comparison Of Simulation Algorithms For The Hopfield Neural Network: An Application Of Economic Dispatch, Tankut Yalçinöz, Hali̇s Altun
Turkish Journal of Electrical Engineering and Computer Sciences
This paper is mainly concerned with an investigation of the suitability of Hopfield neural network structures in solving the power economic dispatch problem. For Hopfield neural network applications to this problem three important questions have been answered: what the size of the power system is; how efficient the computational method; and how to handle constraints. A new mapping process is formulated and a computational method for obtaining the weights and biases is described. A few simulation algorithms used to solve the dynamic equation of the Hopfield neural network are discussed. The results are compared with those of a classical technique, …
