On a variational problem due to the B-Darboux frame in Euclidean 3-space
(Wiley, 2021)In this paper, we introduce a new frame which is called the B-Darboux frame on a surface in Euclidean 3-space. We know that the parallel transport frame is derived from the Frenet frame along a space curve on a surface. ... -
On computing the degree of a Chebyshev Polynomial from its value
(Academic Press Ltd- Elsevier Science Ltd, 2021)Algorithms for interpolating a polynomial f from its evaluation points whose running time depends on the sparsity to f the polynomial when it is represented as a linear combination of t Chebyshev Polynomials of the First ... -
On k-type pseudo null slant helices due to the Bishop frame in Minkowski 3-space E-1(3)
(Amer Inst Mathematical Sciences-Aims, 2020)In this study, we examine k-type pseudo null slant helices due to the Bishop frame, where k is an element of{0, 1, 2}. There are two different cases of the Bishop frame of a pseudo null curve related to the Bishop curvatures. ... -
On LDPC codes for Gaussian interference channels
(Institute of Electrical and Electronics Engineers Inc., 2014)In this paper, we focus on the two-user Gaussian interference channel (GIC), and study the Han-Kobayashi (HK) coding/decoding strategy with the objective of designing low-density parity-check (LDPC) codes. A code optimization ... -
On motion of robot end-effector using the curvature theory of timelike ruled surfaces with timelike directrix
(Universiti Putra Malaysia, 2014)In this paper, we deal with the differential geometric properties of robot end-effector's motion by using the curvature theory of timelike ruled surfaces with timelike directrix. -
On Refinements of Some Integral Inequalities for Differentiable Prequasiinvex Functions
(Univ Nis, Fac Sci Math, 2019)In this paper, using the new and improved form of Holder's integral inequality called Holder-Iscan integral inequality, some new inequalities of the right-hand side of Hermite-Hadamard type inequality for prequasiinvex ... -
On the algebraic construction of cryptographically good 32 x 32 binary linear transformations
(Elsevier Science Bv, 2014)Binary linear transformations (also called binary matrices) have matrix representations over GF(2). Binary matrices are used as diffusion layers in block ciphers such as Camellia and ARIA. Also, the 8 x 8 and 16 x 16 binary ... -
On the algebraic expression of the AES S-box like S-boxes
(2010)In the literature, there are several proposed block ciphers like AES, Square, Shark and Hierocrypt which use S-boxes that are based on inversion mapping over a finite field. Because of the simple algebraic structure of ... -
On the best approximate (P,Q)-orthogonal symmetric and skew-symmetric solution of the matrix equation AXB=C
(Walter De Gruyter Gmbh, 2014)Suppose that the matrix equation AXB-C with unknown matrix X is given, where A, B, and C are known matrices of suitable size. The matrix nearness problem is considered over the (P, Q)-orthogonal symmetric and (P, Q)-orthogonal ... -
On the Construction of 20 x 20 and 24 x 24 Binary Matrices with Good Implementation Properties for Lightweight Block Ciphers and Hash Functions
(Hindawi Ltd, 2014)We present an algebraic construction based on state transform matrix (companion matrix) for n x n (where n + 2(k), k being a positive integer) binary matrices with high branch number and low number of fixed points. We also ... -
On the curvatures of spacelike circular surfaces
(Academic Publication Council, 2016)In this paper a complete system of invariants is presented to study spacelike circular surfaces with fixed radius. The study of spacelike circular surfaces is simplified to the study of two curves: the Lorentzian spherical ... -

On the mixcolumns linear transformation used in AES cipher
(2010)AES block cipher includes a linear transformation called MixColumns which transforms 32-bit input to 32-bit output. This transformation has the property that makes linear and differential attacks harder. In this study, we ... -
On the position and semantics of ein and bir in the nominal phrase: A comparative study
(Gesellschaft fuer deutsche Sprache e.V., 2016)In this paper, we have tried to compare the German word ein to the Turkish word bir. Positionally, the German word ein is placed before a noun (a dress) or a phrase (an old dress) and means a number or an indefiniteness ... -
