اتّحادیه اروپایی سازمان منطقه ای و داوطلبانه است. نقطه آغاز شکل گیری آن در اعلامیه شومان با هدف جلوگیری از جنگ دیگر و فراهم نمودن یکپارچگی اروپا بر اساس صلح و دوستی بود. با انعقاد معاهده پاریس و تشکیل جامعه زغال سنگ و فولاد اروپایی جریان یکپارچگی صلح آمیز اروپا آغاز گردید و موفقیت های چشمگیر جامعه مذکور موجب شد گرایش به یکپارچگی اروپا در این قالب افزایش پیدا کند. در این حین، به منظور هماهنگی با ...
We outline the ACM/IEEE-CS sponsored Computing Curricula project, and then discuss the context and development of its Software Engineering Volume (SE2004).. We then discuss evaluation of the volume, internationalization, the relationship with other disciplines, and the importance of the document’s future evolution.
IEEE 802.11 wireless networks have gained great popularity. However, handoff is always a critical issue in this area. In this paper, we propose a novel seamless handoff mechanism for IEEE 802.11 wireless networks which support IEEE 802.11i security standard. Our approach consists of a Dynamic Tunnel Establishing procedure and a seamless handoff mechanism. Dynamic Tunnel Establishing is for each...

Constant increase in use of wireless infrastructure networks for business purposes created a need for strong safety mechanisms. This paper describes WEP (Wired Equivalent Privacy) protocol for the protection of wireless networks, its security deficiencies, as well as the various kinds of attacks that can jeopardize security goals of WEP protocol: authentication, confidentiality and integrity. T...
A new species of penicillate millipede, from genus Monographis (Diplopoda: Polyxenidae), was collected from Trang Bom and Dinh Quan, within the Dong Nai province, southern Vietnam. Taxonomic characteristics of the genus Monographis Attems, 1907, were used to formally describe this new species. Sensilla of the 6th antennal article and claw structures of Monographis dongnaiensis were c...
Wireless networks are commonly used by people. Market devices are equipped with the new security standard 802.11i. The standard announced in the middle of 2004 is commonly used to protect WLANs. Currently we can find the information that vulnerabilities were found in that standard. Then a question arises: Are WLANs compromised again? The article describes vulnerabilities which were discovered i...
A new species of indotyphlid caecilian amphibian, Gegeneophis tejaswini sp. nov., is described based on eight specimens from lowlands of the most northerly district of the state of Kerala in the southern part of the Western Ghats region, India. This species is distinguished from all other Gegeneophis in annulation characters and genetics (> 6% different from most similar nominal species for ...
فعالیتهای معدنی که از دیرباز بهدلیل اهمیت در تامین مواد اولیه مورد توجه انسان بودهاست، تغییرات بسیاری در محیطزیست از جمله آلودگی هوا به ذرات معلق ایجاد کرده است. این پژوهش با هدف بررسی وضعیت آلودگی ذرات معلق هوای ناحیه صنعتی سیلیسکوبان ازندریان همدان به ذرات معلق انجام یافت. نمونهبرداری از 8 ایستگاه منتخب شامل 5 واحد فعال در مجتمع سیلیسکوبان و 3 ایستگاه منتخب محیطی در اطراف مجتمع با در...
