AC loss characteristics of CORC((R))cable with a Cu former

Terzioğlu, Rıfkı; M. Vojenciak; J. Sheng; F. Gomory; T. F. Cavus; I. Belenli (IOP PUBLISHING LTD, 2017)

High-temperature superconductors from the REBCO (RE = rare earth) family have attained industrial production and their performance is continuously being enhanced. However, cabling technology for high-current (kA range) ...
Comparative analysis and prediction study for effluent gas emissions in a coal-fired thermal power plant using artificial intelligence and statistical tools

Yasin Tunckaya; Köklükaya, Etem (ELSEVIER SCI LTD, 2015)

Environmental sustainability is a crucial phenomenon for daily human life & planet earth, where various plants influence a massive impact to atmosphere as a drawback of the industrial revolutions. The worldwide regulations ...
Comparative prediction analysis of 600 MWe coal-fired power plant production rate using statistical and neural-based models

Yasin Tunckaya; Köklükaya, Etem (ELSEVIER SCI LTD, 2015)

Electrical energy is a crucial phenomenon for daily human life & industry, and various types of production plants such as nuclear, thermal, wind, geothermal, hydro, biomass, solar, etc. are developed with distinct advantages ...
Comparison of segmentation algorithms for detection of hotspots in bone scintigraphy images and effects on CAD systems

Ali Aslantas; Dandıl, Emre; Çakıroğlu, Murat (ALLIED ACAD, 2017)

The bone scintigraphy scan is one of the most common diagnostic procedures in nuclear medicine for detection of bone metastases. All involvements detected by the imaging process are called hot spots, whether or not they ...
Design and Testing of Coils Wound Using the Conductor-On-Round-Tube (CORT) Cable

Fedor Gomory; Jan Souc; Michal Vojenciak; Terzioğlu, Rıfkı; Lubomir Frolek (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2017)

Alternative concept for winding of coils from high-temperature superconducting tapes has been investigated. Conductor-On-Round-Tube (CORT) conductors with tapes helically wound on a metallic tube have been manufactured and ...
Design optimization of distribution transformers with nature-inspired metaheuristics: a comparative analysis

Alhan, Levent; Yumuşak, Nejat (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2017)

Many economies in the world have adopted energy-efficiency requirements or incentive programs mandating or promoting the use of energy-efficient transformers. On the other hand, increases in transformer efficiency are ...
Determination of Fatigue Following Maximal Loaded Treadmill Exercise by Using Wavelet Packet Transform Analysis and MLPNN from MMG-EMG Data Combinations

Gurkan Bilgin; I. Ethem Hindistan; Y. Gul Ozkaya; Köklükaya, Etem; Ovunc Polat; Omer H. Colak (SPRINGER, 2015)

The muscle fatigue can be expressed as decrease in maximal voluntary force generating capacity of the neuromuscular system as a result of peripheral changes at the level of the muscle, and also failure of the central nervous ...
Discrete design optimization of distribution transformers with guaranteed optimum convergence using the cuckoo search algorithm

Alhan, Levent; Yumuşak, Nejat (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2017)

Transformer design optimization methods presented in the literature rarely yield solutions directly applicable in production; the design engineer usually needs to convert the theoretical solution to a practical one. This ...
EFFECT OF PARTICLE-SIZE ON THE SPONTANEOUS HEATING OF A COAL STOCKPILE

Akgün, Fehmi (ELSEVIER SCIENCE INC, 1994)

A large-scale apparatus has been used to evaluate the effect of particle size on the spontaneous heating of a coal stockpile. To accomplish this, coal with various ranges of particle size (between 2 and 50 mm in diameter) ...
Numerical Study on Magnetization Characteristics of Superconducting Conductor on Round Core Cables

Jie Sheng; Michal Vojenciak; Terzioğlu, Rıfkı; Lubomir Frolek; Fedor Gomory (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2017)

This paper presents numerical study on magnetization characteristics of conductor on round core (CORC) cable. Numerical-models introduced in this paper are based on finite-element method (FEM) with simplified structure, ...
