Invariant Magnetic Vector Potential in the Mercury Based HighTemperature Superconductor and Its Prospective Technological Application

Özdemir, Z. Güven (2018)

Magnetic vector potential, A has great importance in various superconducting phenomena such as Aharonov-Bohm effect, Josephson effect, SQUID applications etc. due to the fact that A is directly related to the phase ...
Influence of Local Soil Conditions on the Structural Design and Associated Costs

İnce, Harun; Toy, Ebru; Tolon, Tolon (2018)

It is known that earthquakes occur along the faults as a result of the tectonic plate movements [1]. The North Anatolian, Northeast Anatolian and East Anatolian Faults create three major fault lines in Turkey. In connection ...
Failure Analysis of Jet Turbine Engine High Pressure Nozzle Material Made of Cobalt Based Super Alloy

Çoban, Ozan; Arslan, Özgür C.; Karahan, Tuba (2018)

: In this study, we carried out the failure analysis based on metallographic research of a cobalt superalloy material which had been used in jet turbine engine. The failure analysis was made by chemical composition analysis, ...
Golden Ratio Discovered in Nonlinear Superconductor

Aslan Çataltepe, Özden; Güven Özdemir, Zeynep; Onbaşlı, Ülker (2018)

Mercury based high temperature superconductor as a nonlinear dynamical system constitutes a natural laboratory for searching quantum chaotic transitions. In our previous works, these chaotic transitions had been expressed ...
The Experiment and Simulation Results of Speed Control of Permanent Magnet Synchronous Motor by Using Fuzzy Controller

Teker, Aykut; Kuyumcu, F. Erfan (2018)

Spouted Bed Drying Characteristics of Rosehip (Rosa Canina L.)

Evin, Duygu (2019)

Drying kinetics, effective moisture diffusivity and activation energy of rosehip (Rosa Canina L.) dried in a spouted bed dryer were investigated. The effects of the spouted bed drying and the inlet air temperature in the ...
Kinetic Investigation of Boronized 34CrAlNi7 Nitriding Steel

TOPUZ, Polat; AYDOĞMUŞ, Tuna; AYDIN, Özlem (2019)

In this study, kinetic examinations of boronized 34CrAlNi7 Nitriding Steel samples were described. Samples were boronized in indirect heated fluidized bed furnace consists of Ekabor 1™ boronizing agent at 1123, 1223 and ...
Analysis of Different Engine Types in Aircrafts with Exergetic Approach

CENGİZ, Aysun; UTLU, Zafer (2019)

The main purpose of exergy analysis is to determine the maximum possible work that can be obtained and to decrease inefficiencies on the system. Exergy analysis provides information about the intensity and positions ...
Simulation of rice straw gasification in bubbling bed reactor using ASPEN PLUS

Sezer, Senem; Özveren, Uğur (2019)

: The global dependence on fossil fuels and the environmental effects of them are some of the factors that urge research on using biomass sources. Gasification is a process which converts carbonaceous materials into syngas. ...
Some Curvature Properties of Generalized Complex Space Forms

Mutlu, Pegah (2019)

The object of the present paper is to study generalized complex space forms satisfying curvature identities named Walker type identities. Also It is proved that the difference tensor R. ̃ – ̃.R and the Tachibana tensor ...
Smart Building Technology for Nano-Architecture

Elcin Sungur, Selale (2019)
