  • A distributed measurement architecture for inferring TCP round-trip times through passive measurements 
    Abut, Fatih (TURKISH JOURNAL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCES / TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2019)
    The round-trip time (RTT), defined as the time elapsed for transmission of a data packet to travel from one endpoint to the other and back again, is an important parameter for Internet quality. This paper proposes an ...
  • A robust ensemble feature selector based on rank aggregation for developing new VO(2)max prediction models using support vector machines 
    Abut, Fatih; Akay, Mehmet Fatih; George, James (TURKISH JOURNAL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCES / TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2019)
    This paper proposes a new ensemble feature selector, called the majority voting feature selector (MVFS), for developing new maximal oxygen uptake (VO(2)max) prediction models using a support vector machine (SVM). The ...
  • A robust polynomial regression-based voice activity detector for speaker verification 
    Disken, Gokay; Tufekci, Zekeriya; Cevik, Ulus (EURASIP JOURNAL ON AUDIO SPEECH AND MUSIC PROCESSING / SPRINGER INTERNATIONAL PUBLISHING AG, 2017-10)
    Robustness against background noise is a major research area for speech-related applications such as speech recognition and speaker recognition. One of the many solutions for this problem is to detect speech-dominant regions ...
  • DSP controlled voltage disturbance generator 
    Savrun, Murat Mustafa; Tan, Adnan; Koroglu, Tahsin; Cuma, Mehmet Ugras; Bayindir, Kamil Cagatay; Tumay, Mehmet (JOURNAL OF ELECTRICAL SYSTEMS / ENGINEERING & SCIENTIFIC RESEARCH GROUPS, 2018-03)
    Voltage disturbance generator (VDG) is a kind of device used to generate voltage disturbances that may occur in the network in order to test and evaluate the performance of the power quality devices such as Dynamic Voltage ...
  • Exciton localization and structural disorder of GaAs1-xBix/GaAs quantum wells grown by molecular beam epitaxy on (311)B GaAs substrates 
    Prando, G. A.; Orsi Gordo, V.; Puustinen, J.; Hilska, J.; Alghamdi, H. M.; Som, G.; Gunes, M.; Akyol, M.; Souto, S.; Rodrigues, A. D.; Galeti, H. V. A.; Henini, M.; Galvao Gobato, Y.; Guina, M. (SEMICONDUCTOR SCIENCE AND TECHNOLOGY / IOP PUBLISHING LTD, 2018-08)
    In this work, we have investigated the structural and optical properties of GaAs(1-x)Bix/GaAs single quantum wells (QWs) grown by molecular beam epitaxy on GaAs (311)B substrates using x-ray diffraction, atomic force ...
  • IWD Based Feature Selection Algorithm for Sentiment Analysis 
    Parlar, Tuba; Sarac, Esra (ELEKTRONIKA IR ELEKTROTECHNIKA / KAUNAS UNIV TECHNOLOGY, 2019)
    Feature selection methods aim to improve the classification performance by eliminating non-valuable features. In this paper, our aim is to apply a recent optimization technique namely the Intelligent Water Drops (IWD) ...
  • Prediction of gross calorific value of coal based on proximate analysis using multiple linear regression and artificial neural networks 
    Acikkar, Mustafa; Sivrikaya, Osman (TURKISH JOURNAL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCES / TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2018)
    Gross calorific value (GCV) of coal was predicted by using as-received basis proximate analysis data. Two main objectives of the study were to develop prediction models for GCV using proximate analysis variables and to ...
  • Scale-invariant MFCCs for speech/speaker recognition 
    Tufekci, Zekeriya; Disken, Gokay (TURKISH JOURNAL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCES / TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2019)
    The feature extraction process is a fundamental part of speech processing. Mel frequency cepstral coefficients (MFCCs) are the most commonly used feature types in the speech/speaker recognition literature. However, the ...
  • Sliding mode PI control with backstepping approach for MIMO nonlinear cross-coupled tank systems 
    Aksu, Inayet Ozge; Coban, Ramazan (INTERNATIONAL JOURNAL OF ROBUST AND NONLINEAR CONTROL / WILEY, 2019-07)
  • Synthesis and fabrication of Mg-doped ZnO-based dye-sensitized solar cells 
    Polat, Ismail; Yilmaz, Salih; Bacaksiz, Emin; Atasoy, Yavuz; Tomakin, Murat (JOURNAL OF MATERIALS SCIENCE-MATERIALS IN ELECTRONICS / SPRINGER, 2014-10)
    Undoped and 2, 4 and 6 at.% Mg-doped ZnO nanorods were successfully deposited on ZnO seeded fluorine tin oxide substrates by a simple chemical bath deposition technique to form a photoanode. It was seen that all the samples ...
  • Theoretical analysis of doping management and its effects on power scaling 
    Tandirovic Gursel, Amira; Elahi, Parviz; Ilday, Fatih Omer; Ozyazici, Mustafa Sadettin (TURKISH JOURNAL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCES / TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2016)
    Thermal load and nonlinear effects are two contrary phenomena that make up important drawbacks in rapid progress of high-power fiber lasers. To minimize the thermal load, which limits the average power, doping concentration ...
