On a New Class of Meromorphic Univalent Function Associated with Dziok_Srivastava Operator
Journal of Kufa for Mathematics and Computer, 2014 In this paper, we introduce and study a new class of meromorphic Univalent functions deï¬ned by Dziok_Srivastava operator for this class. We obtain coefficient inequality, convex set, closure and Hadamard product (or convolution).Further we obtain a(n,δ

Octal Bent Generalized Boolean Functions [PDF]
, 2011 In this paper we characterize (octal) bent generalized Boolean functions defined on $\BBZ_2^n$ with values in $\BBZ_8$. Moreover, we propose several constructions of such generalized bent functions for both $n$ even and $n ...

Development and evaluation of a Hadamard transform imaging spectrometer and a Hadamard transform thermal imager [PDF]
A spectrometric imager and a thermal imager, which achieve multiplexing by the use of binary optical encoding masks, were developed. The masks are based on orthogonal, pseudorandom digital codes derived from Hadamard matrices.

PAPR reduction of optical OFDM signals in visible light communications
ICT Express, 2019 Orthogonal frequency division multiplexing (OFDM) is extensively used in optical communications to achieve high rate transmission. In this paper, Vandermonde like matrix (VLM) pre-coding approach is offered to reduce the high peak-to-average power ratio (

IMAGE COMPRESSION BY USING WALSH AND FRAMELET TRANSFORM
Mağallaẗ Al-kūfaẗ Al-handasiyyaẗ, 2019 In this paper, Framelet and Walsh transform are proposed for transformation, and then using arithmetic coding for compress an image. The goal is to achieve higher compression ratio by applying two levels Framelet transform (FLT), and then apply 2D Walsh ...

Transform coding of DCT coefficients in video encoder
Tongxin xuebao, 2008 The redundancy among discrete cosine transform（DCT） coefficients in video encoder was found very strong,a method for subband decomposition and transform coding was proposed.Each 8×8 DCT spectrum date of macroblock was regrouped to gather the same ...

Matrix Factorization and Some Fast Discrete Transforms
AxiomsIn this paper, three discrete transforms related to vector spaces over finite fields are studied. For our purposes, and according to the properties of the finite fields, the most suitable transforms are as follows: for binary fields, this is the Walsh ...

A Novel Autofocus Measure Based on Weighted Walsh-Hadamard Transform
IEEE Access, 2019 The autofocus measure plays an important role in passive digital imaging systems. However, most of the existing methods are more sensitive to the noise. In order to overcome this drawback, we proposed a novel autofocus measure based on the weighted Walsh-
