در ادراه امور سازمان نیز از تکنولوژی data base در دو زمینه مشخص یعنی بصورت سیستم های عملیاتی و سیستم های اطلاعاتی میتوان استفاده کرد. در شرایط کنونی وجود موانع متعدد از قبیل فرهنگ غالب در سازمان های بزرگ و طرز تلقی مدیران دیوان سالار از یکطرف و تازه گی و پیچیده بودن فنون مربوط به سیتم های data base فقدان دانش، تجربه و تخصص کافی برای بهره گیری کامل از آن از طرف دیگر، برنامه ریزی و اقدام برای ایج...
Chemical stability in propellants is important issue. In this article chemical and thermal stability for two kinds of double and single base propellants are investigated. In mass loss test in 90 0C, after 18 days mass loss for both samples is no more than 3%. By stabilizer measurement it was evident that remaining stabilizer content in aged samples are more than 10% in relative to fresh samples...
The wireless industry is experiencing a great revolution in order to meet the expectations of the end users. In mobile multi-hop DTSP algorithm, the available bandwidth resources are increased by partitioning each time slot into several minislots wherein different numbers of minislots are allocated to different users. The mobile multi-hop DTSP algorithm is based on asynchronous time-division mu...
A mobile ad-hoc network is an autonomous system of mobile routers that are self-organizing and completely decentralized with no requirements for dedicated infrastructure support. However, such infrastructure in terms of base stations is available in many popular areas already. These base stations often offer high-speed data connectivity to a wired network. In this paper, we describe an approach...
In small cell networks, high mobility of users results in frequent handoff and thus severely restricts the data rate for mobile users. To alleviate this problem, we propose to use heterogeneous, two-tier network structure where static users are served by both macro and micro base stations, whereas the mobile (i.e., moving) users are served only by macro base stations having larger cells; the id...
Due to a tremendous increase in mobile traffic, operators have started restructure their networks offload traffic. New research directions will lead fundamental changes the design of future Fifth-generation (5G) cellular networks. For formal reason, study solves physical network base station for prediction best characteristics develop an enhanced with help graph theory. Any number that can be u...
