On Energy Waves Via Airy Functions in Time-Domain
(European Journal Pure & Applied Mathematics, 2016)The main idea is to solve the system of Maxwell's equations in accordance with the causality principle to get the energy quantities via Airy functions in a hollow rectangular waveguide. Evolutionary Approach to Electromagnetics ... -
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 ternary biquadratic Diophantine equation 11(x(2) - y(2))
(Bulgarian Acad Science, 2019)We obtain infinitely many non-zero integer triples (x, y, z) satisfying the non- homogeneous bi-quadratic equation with three unknowns 11(x(2) - y(2)) + 3(x+ y) = 10z(4). Various interesting properties among the values of ... -
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 ... -
