This paper describes a library of parameterized arithmetic operators for manipulating high-dynamic numbers on FPGA. It support both floating-point and logarithmic representations. Along with its direct interest, that library allow application-specific comparisons of those two number representation systems. It is unbiased in the sense that it tends to reflect the state-of-the-art for both number...

We describe an algorithm for the numerical solution of an integral equation of the form

The quadratic-phase Fourier transform (QPFT) has gained much popularity in recent years because of its applications image and signal processing. However, the QPFT is inadequate for localizing spectrum, which required some applications. In this paper, wave packet (QP-WPT) proposed to address problem, based on (WPT) QPFT. Firstly, we propose definition QP-WPT give relation with windowed (WFT). Se...

Chemical-reaction optimization not only increases the yield of chemical processes but also reduces impurities and improves performance resulting products, contributing to important innovations in various industries. This paper presents a novel barycentric kernel for chemical-reaction using Bayesian (BO), powerful machine-learning method designed optimize costly black-box functions. The is speci...

The 2-dimensional logarithmic number system (2DLNS), a subset of the multi-DLNS (MDLNS), which has similar properties to the classical Logarithmic Number System (LNS), provides more degrees of freedom than the LNS by virtue of having two orthogonal bases and has the ability to use multiple 2DLNS components, or digits. The second base in 2DLNS can be adjusted to improve the representation space ...

objective: yield components and genetic contribution have the most important in final yield and breeding programs of crop plants. for this purpose, 20 varieties of grapevines with russia origin were evaluated in urmia and takestan research station (under full irrigation and drought stress). methods: twenty grapevine genotypes were evaluated in urmia and takestan research station (under full irr...

A bstract We study one-loop covariant effective action of “non-minimally coupled” $$ \mathcal{N} N = 1, d 4 Einstein-Maxwell supergravity theory by heat kernel tool. By fluctuating the fields around classical background, we functional determinant Laplacian differential operator following Seeley-DeWitt techniq...
