The design of an optimizing compiler for a large and rich language poses problems beyond those of sheer size and cost. One of the most serious is that the wealth and variety of the language makes it possible to express the same logical function in terms of many different source constructs. The choice may be based on naturalness of language use, program readability, ease of debugging, compil...

background & aim: restrictions on the use of synthetic antioxidant such as butylated hydroxyanisole (bha) and butylated hydroxytoluene (bht) are being imposed because of their carcinogecity . experimental: in this investigation, optimization of phenolic extraction process from methanolic (80%) extract (v/v) of  flomideschema parviflorum through response surface methodology by fulin cio-calt...

BACKGROUND Analysis and extraction of plant matrices are important processes for the development, modernization, and quality control of herbal formulations. Response surface methodology is a collection of statistical and mathematical techniques that are used to optimize the range of variables in various experimental processes to reduce the number of experimental runs, cost , and time, compared ...

candida species are the most common cause of opportunistic fungal infection worldwide. due to increasing resistance of fungi against conventional drugs, as well as their side effects, alternative natural products have become a renewed interest. in the current study, the anti-candida activities of scrophularia striata extract were examined. in this experimental study, microdilution assay and wel...

one of important problems in supply chains management is supplier selection. in a company, there are massive data from various departments so that extracting knowledge from the company’s data is too complicated. many researchers have solved this problem by some methods like fuzzy set theory, goal programming, multi objective programming, the liner programming, mixed integer programming, analyti...

The emergence of multimedia data in databases requires adequate methods for information retrieval. In a music data retrieval system by humming, the first stage is to extract exact pitch periods from a flow of signals. Due to the complexity of speech signals, it is difficult to make a robust and practical pitch tracking system. We adopt genetic algorithm in optimizing the control parameters for ...

I give a brief introduction to the scope of lattice QCD calculations in our eeort to extract the fundamental parameters of the standard model. This goal is illustrated by two examples. First I discuss the extraction of CKM matrix elements from measurements of form factors for semi-leptonic decays of heavy-light pseudoscalar mesons such as D ! Kee. Second, I present the status of results for the...

Bumpmodeling is a method used to extract oscillatory bursts in electrophysiological signals, who are most likely to be representative of local synchronies. In this paper we present an improved sparse bump modeling method. The improvements are done in the adaptation method by optimizing the parameters according to the order of their derivatives; and in the window matching method by changing the ...

Many software engineering tools such as program slicers must perform data-flow analysis in order to extract necessary information from the program source. These tools typically borrow much of their implementation from optimizing compilers. However, since these tools are expected to analyze programs in their entirety, rather than functions in isolation, the time and space performance of the data...

We propose an entirely novel family of score functions for blind signal separation BSS , based on the family of mixture generalized gamma density which includes generalized gamma, Weilbull, gamma, and Laplace and Gaussian probability density functions. To blindly extract the independent source signals, we resort to the FastICA approach, whilst to adaptively estimate the parameters of such score...
