Success often comes through many small, incremental, well-executed improvements.

the telecommunications industry plays an important role in providing ict services to a wide range of customers. in addition to individual customers, corporate customers also are user of these services and have an important role to make return on investment for telecom companies (telcos). therefore, this group of customers should not be ignored by any reason. this is where the telecom companies ...

This paper is focusing on the nondesirable nonlinear effects of power amplifiers for wireless communication. One of the most-used methods for amplifier nonlinearities reducing – digital baseband adaptive predistortion is presented.

The goal of theory of constraints (TOC) is to maximize output, which is achieved byidentifying and managing the critically constrained resources. To manage the constraints, Goldrattproposed five focusing steps (5FS). If we increase constrained output, the output of system will beincreased. In this paper, we focus on step four of the 5FS and use the remained capacity of nonconstraintto elevate t...

A series of 42 Pyrazolo[4,3-h]quinazoline-3-carboxamides as multi-cyclin-dependent kinaseinhibitors regarded as promising antitumor agents to complement the existing therapies, wassubjected to a three-dimensional quantitative activity relationship (3D QSAR). Different QSARmethods, comparative molecular field analysis (CoMFA), CoMFA region focusing, andcomparative molecular similarity indices an...

The performance features of line-focused laser ablation for the characterization of interfaces in layered materials by laser-induced plasma spectrometry (LIPS) have been compared with the point-focusing method in terms of signal precision, signal-to-noise ratio, ablation rates, and surface sensitivity. In both optical configurations a pulsed Nd:YAG laser beam operating at 532 nm, with a homogen...
