In this paper, we obtain some interesting properties of differential subordination and superordination for the classes of symmetric analytic functions in the unit disk, by applying Noor integral operator. We investigate several sandwich theorems on basis of this theory.

Iteration is a central issue in the management of product development (PD) projects. Iteration is often recognized as a major source of increased PD lead-time and cost, a key driver of schedule risk, and a source of major uncertainties in the commitment of resources. However, iteration, when planned and managed effectively, can overcome the uncertainties inherent in interdependent development a...

A wide range of new research articles in artificial intelligence, logic programming, and other applied sciences are based on fixed-point theorems. The aim this article is to present an approximation method for finding the fixed point generalized Suzuki nonexpansive mappings hyperbolic spaces. Strong Δ-convergence theorems proved using Noor iterative process (GSNM) uniform convex Due richness sp...

This paper examines design iteration and its modelling in the simulation of New Product Development (NPD) processes. A framework comprising six perspectives of iteration is proposed and it is argued that the importance of each perspective depends upon domain-specific factors. Key challenges of modelling iteration in process simulation frameworks such as the Design Structure Matrix are discussed...

In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...

Weight functions with a parameter are introduced into an iteration process to increase the order of the convergence and enhance the behavior of the iteration process. The parameter can be chosen to restrict extraneous fixed points to the imaginary axis and provide the best basin of attraction. The process is demonstrated on several examples.

SUMMARY Recently the GMRESR inner-outer iteration scheme for the solution of linear systems of equations has been proposed by Van der Vorst and Vuik. Similar methods have been proposed by Axelsson and Vassilevski 1] and Saad (FGMRES) 10]. The outer iteration is GCR, which minimizes the residual over a given set of direction vectors. The inner iteration is GMRES, which at each step computes a ne...

The growth of Saccharomyces rouxii and Saccharomyces mellis, which are two of the main spoilage organisms of dates, can be inhibited by various treatments. The most effective treatment found in this study that did not affect flavor consisted of a predip of the dates in 2% potassium sorbate solution followed by injection of methyl bromide into the sealed package.

The traveling salesman problem (TSP) is one of the most important combinational optimization problems that have nowadays received much attention because of its practical applications in industrial and service problems. In this paper, a hybrid two-phase meta-heuristic algorithm called MACSGA used for solving the TSP is presented. At the first stage, the TSP is solved by the modified ant colony s...
