A Comparison of Boundary Element and Spectral Collocation Approaches to the Thermally Coupled MHD Problem
Bozkaya, Canan; Türk, Önder (2021-05-03)
The first homology of a real cubic is generated by lines

The Only Complex 4-net is the Hesse Configuration
Kişisel, Ali Ulaş Özgür (2020-06-12)
It has been conjectured that the only nets realizable in CP2 are 3-nets and the Hesse configuration (up to isomorphism). The goal of this talk will be to outline our proof, together with A. Bassa, of this conjecture. A pre...

Ozan, Yıldıray (2020-6-06)
A Survey on Spacetime Geometries and Relativistic Models
Okutmuştur, Baver (null; 2019-12-23)
Our analysis starts with the flat geometry, so-called Minkowski spacetime, and follows by further generalizations on specific spherically symmetric geometries whose metric elements describe solutions to the Einstein’s fiel...
On The Extrapolated Vms-Pod Method Forıncompressible Flows
Güler Eroğlu, Fatma; Kaya Merdan, Songül (2019-12-11)
In this study, proper orthogonal decomposition based reduced-order modelling and variational multiscale stabilization method are utilized for the incompressible Navier-Stokes equations. In addition, the difficulties result...
k-existentially closed groups

A Numerical Study of a Modular Sparse Grad-Div Stabilization Method for Boussinesq Equations
Demir, Medine; Kaya Merdan, Songül (2019-10-10)
This study presents a modular sparse grad-div stabilization method for solving the Boussinesq equations. Unlike the usual grad-div stabilization which produces fully coupled block matrices, the proposed stabilization metho...
A CSCM approximation of steady MHD flow and heat transfer between parallel plates with hydrodynamic slip and convective boundary conditions
Tezer, Münevver; Türk, Önder (null; 2019-10-04)
The steady magnetohydrodynamic (MHD) flow together with its heat transfer between parallel plates is considered in which the electrically conducting fluid has temperature dependent properties such as viscosity, thermal and...
Counting Boolean Functions with Faster Points
Salagean, Ana; Özbudak, Ferruh (null; 2019-03-31)
Duan and Lai introduced the notion of “fast point” for a Boolean function f as being a direction a so that the algebraic degree of the derivative of f in direction a is strictly lower than the expected deg (f) - 1. Their s...
Subspace Packings
Etzion, Tuvi; Kurz, Sascha; Otal, Kamil; Özbudak, Ferruh (2019-03-31)
The Grassmannian Gq(n,k) is the set of all k-dimensional subspaces of the vector space Fnq. It is well known that codes in the Grassmannian space can be used for error-correction in random network coding. On the other hand...
Fdm solution of mhd flow in a rectangular duct with slipping and partly insulated partly conducting side walls
Arslan, Sinem; Tezer, Münevver (IOP Publishing; 2019-01-01)
The magnetohydrodynamic (MHD) flow of an electrically conducting fluid is considered in a long channel (pipe) of rectangular cross-section in which the fluid is driven by a pressure gradient and the flow is steady, laminar...
Construction of Some Codes Suitable for Both Side Channel and Fault Injection Attacks
Carlet, Claude; GÜNERİ, CEM; Mesnager, Sihem; Özbudak, Ferruh (2018-12-30)
Using algebraic curves over finite fields, we construct some codes suitable for being used in the countermeasure called Direct Sum Masking which allows, when properly implemented, to protect the whole cryptographic block c...
Characterizations of Partially Bent and Plateaued Functions over Finite Fields
Mesnager, Sihem; Özbudak, Ferruh; SINAK, AHMET (2018-12-30)
Partially bent and plateaued functions over finite fields have significant applications in cryptography, sequence theory, coding theory, design theory and combinatorics. They have been extensively studied due to their vari...
A Numerical study of second order time stepping methods for the boussinesq equations
Demir, Medine; Çıbık, Aytekin Bayram; Kaya Merdan, Songül (null; 2018-10-21)
The Boussinesq approximation is a way to solve nonisothermall flow such as natural convection prob-lems, without having to solve for the full compressible formulation of the Navier-Stokes equations.Natural convection is re...
Numerical Aspects of POD-Based Reduced-Order Modeling forDarcy-Brinkman Equations
Güler Eroğlu, Fatma; Kaya Merdan, Songül (2018-10-21)
We propose, analyze and test a reduced order modelling with proper orthogonal decomposition (POD) method for the modeling to flows governed by double diffusive convection, which models flow driven by two potentials with di...
MHD natural convection flow in a porous cavity
Bozkaya, Canan (null; 2018-09-13)
A numerical investigation of natural convection flow in a cavity filled with a fluid-saturated porous medium in the presence of uniform magnetic field is performed. The steady, viscous, incompressible flow inside the porou...
