  • On the Moduli Space of Flat Tori Having Unit Area 
    Saglam, Ismail (International Electronic Journal of Geometry (IEJG) / Kazım İLARSLAN, 2021-04)
    Inspiring from Thurston's asymmetric metric on Teichmüller spaces, we define and study a natural (weak) metric on the Teichmüller space of the torus. We prove that this weak metric is indeed a metric: it separates points ...
  • Passive Flow Control around NACA 0018 Airfoil Using Riblet at Low Reynolds Number 
    Guler, Emre; Durhasan, Tahir; Karasu, Ilyas; Akbiyik, Hurrem (Iğdır Üniversitesi Fen Bilimleri Enstitüsü Dergisi (FBED) = Journal of The Institute of Science and Technology (JIST) / Iğdır Üniversitesi, 2021-09)
    In this study, aerodynamic capabilities of NACA 0018 airfoil is numerically investigated by installing riblet on the suction side of airfoil. Numerical results were obtained by ANSYS Fluent using k-kl-kw transition model ...
  • The Turbulence Intensity Effect on the Flow Characteristics and Aerodynamics of a Circular Cylinder 
    Karasu, Ilyas; Tumse, Sergen (Çukurova Üniversitesi Mühendislik-Mimarlik Fakültesi Dergisi = Cukurova University Journal of the Faculty of Engineering / Çukurova Üniversitesi, 2021-12)
    In this investigation, a numerical study about the turbulence intensity effect on the time-dependent flow structure around a circular cylinder employing k-ω based Detached Eddy Simulation (DES) turbulence model was performed ...
  • Image processing based autonomous landing zone detection for a multi-rotor drone in emergency situations 
    Turan, Veysel; Avsar, Ercan; Asadihendoustani, Davood; Avsar Aydin, Emine (Turkish Journal of Engineering / Murat YAKAR, 2021-10)
    Flight safety and reliability improvement is an important research issue in aerial applications. Multi-rotor drones are vulnerable to motor failures leading to potentially unsafe operations or collisions. Therefore, ...
  • Silindir Etrafındaki Kararsız Akışın Farklı Türbülans Modelleri ile Sayısal Olarak İncelenmesi 
    Karasu, Ilyas (Bilecik Şeyh Edebali Üniversitesi Fen Bilimleri Dergisi / Bilecik Şeyh Edebali Üniversitesi, 2019)
    Bu çalışmada, kritik altı olan 5000 Reynolds sayısında silindir etrafındaki kararsız akış farklı türbülans modelleri ile sayısal olarak incelenmiş ve bu modellerin performansları test edilmiştir. Çalışmada, aynı şartlarda ...
  • The Effect of Limestone in Breast Cancer Detection by Microwaves 
    Avsar Aydin, Emine (Çukurova Üniversitesi Mühendislik-Mimarlik Fakültesi Dergisi / Çukurova Üniversitesi, 2017)
    Meme kanseri dünyada kadınlar arasındaki en yaygın kanser türüdür. Kanserin ilk aşamasındaki tespit, tümörlerin kontrolsüz olarak çoğalmasından ve diğer organlara yayılması açısından çok önemlidir. Mikrodalga görüntüleme ...
  • Complete flat cone metrics on punctured surfaces 
    Saglam, Ismail (TURKISH JOURNAL OF MATHEMATICS / SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2019)
    We prove that each complete flat cone metric on a surface with regular or irregular punctures can be triangulated with finitely many types of triangles. We derive the Gauss-Bonnet formula for this kind of cone metrics. In ...
  • A PRELIMINARY STUDY FOR EARLY BREAST CANCER DETECTION WITH MICROWAVES 
    Avsar Aydin, Emine (TEHNICKI GLASNIK-TECHNICAL JOURNAL / UNIV NORTH, 2018-06)
    Breast cancer is the most common type of cancer in female all over the world. Early detection and treatment gives a chance to overcome this cancer. In breast cancer detection, there are many methods such as X-ray mammography, ...
  • 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 ...
  • EVALUATION OF LIMESTONE LAYER'S EFFECT FOR UWB MICROWAVE IMAGING OF BREAST MODELS USING NEURAL NETWORK 
    Aydin, Ahmet; Avsar Aydin, Emine (TEHNICKI GLASNIK-TECHNICAL JOURNAL / UNIV NORTH, 2017-07)
    X-ray mammography is widely used for detection of breast cancer. Besides its popularity, this method did not have the potential of discriminating a tumor covered with limestone from a pure limestone mass. This might cause ...
  • AN APPROXIMATE SOLUTION FOR THE PLANE WAVE DIFFRACTION BY AN IMPEDANCE STRIP: H-POLARIZATION CASE 
    Aydin, Emine Avsar; Ikiz, Turgut (TEHNICKI GLASNIK-TECHNICAL JOURNAL / UNIV NORTH, 2016-12)
    In this study, the diffraction of H-polarized plane wave by an infinitely long strip which has the same impedance on both faces with a width of 2a is investigated by using an analytical-numerical method. The diffracted ...
