During the last few years, access to heterogeneous data sources and integration of the disparate data has emerged as one of the major areas for growth of database management software. Digital's DB Integrator provides robust data access by supporting heterogeneous query optimization, location transparency, global consistency, resolution of semantic differences, and security checks. A global cata...

Future mobile networking will involve the convergence of different wireless networks such as 2G, 3G, WiMax and Long Term Evolution. The wide scale deployment of such heterogeneous networks will precipitate a radical change in the network infrastructure, where currently closed systems such as 3G will have to operate in an open environment. This brings to the fore certain security issues which mu...

The study highlights the importance to develop the national economy through assuring energy security. The study aims to analyze how to develop renewable energy sources, determine the main priorities of Ukraine’s national security policy and discover novel ways of assuring energy security due to developing the industry of renewable energy in the light of environmental safety, energy conservation...

National security depends on soft power, the ability of a country to generate and use its economic power and to project its national values. It also depends on long-term factors that contribute to economic growth and increase the total resources base available not only for defense but to provide economic security in the form of income and business opportunities for individuals. The economic iss...

Paper documents are routinely found in general litigation and criminal and terrorist investigations. The current state-of-the-art processing of these documents is to simply OCR them and search strictly the text. This ignores all handwriting, signatures, logos, images, watermarks, and any other non-text artifacts in a document. Technology, however, exists to extract key metadata from paper docum...

In this work, the SBA-15-supported dithizone-copper(I) [SBA-15-dtz–Cu(I)] complex as a new heterogeneous catalyst is prepared for the first time. The catalyst prepared is characterized by the FT-IR spectroscopy, SEM, and ICP techniques. This reusable heterogeneous catalyst can be used in the click reactions for the green and facile synthesis of 1,4-disubstituted 1,2,3-triazolesvia a on...

Future 4G mobile communication networks are expected to provide all IP-based services for heterogeneous wireless access technologies, assisted by mobile IP to provide seamless Internet access for mobile users. Two major challenges in developing such heterogeneous network infrastructure are QoS provisioning and security services for mobile users’ communication flows. This paper proposes a new ar...

Designing of heterogeneous wireless environment involves several internetworking issues, such as seamless handoff or roaming, mobility management, security and accounting problem etc. One of the major issues in next– generation heterogeneous networks is the issue of vertical handoff for guaranteeing service continuity and quality of service. This paper reports on the design and implementation o...
