Microwave Access (WiMAX) and Long-Term Evolution (LTE) are considered the best technologies for vehicular networks. WiMAX and LTE are Fourth-Generation (4G) wireless technologies that have well-defined quality of service (QoS) and security architectures.Existing work QoS-aware distributed security architecture using the elliptic curve Diffie– Hellman (ECDH) protocol that has proven security str...

As envisioned some seven years ago, the Next Generation Network (NGN) with its emphasis on ubiquitous services was to revolutionize the lives of its users. The NGN, resulting from the merger of telecommunications, Information Technology (IT) and the Internet would provide on-demand, always-on services to its users. Service providers were to be affected by the increase in revenues paid by the us...

increasing the popularity of sip based services (voip, iptv, ims infrastructure) lead to concerns about its ‎security. the main signaling protocol of next generation networks and voip systems is session initiation protocol ‎‎(sip). inherent vulnerabilities of sip, misconfiguration of its related components and also its implementation ‎deficiencies cause some security concerns in sip based infra...

Next Generation Network (NGN) services have been the focus to the researchers and practitioners as the new converging paradigm of IP-based telecommunication and Information and Communication Technologies (ICT) services. Even though, fundamentally NGN services have some common to web services mainly on the service composition, service discovery, service creation and service delivery, NGN service...

OBJECTIVE To develop a conceptual framework for the design of an in-home monitoring system (IMS) based on the requirements of older adults with vision impairment (VI), informal caregivers and eye-care rehabilitation professionals. MATERIALS AND METHODS Concept mapping, a mixed-methods statistical research tool, was used in the construction of the framework. Overall, 40 participants brainstorm...

IMS (IP Multimedia Subsystem) is the technology that will merge the Internet (packet switching) with the cellular world (circuit switching). Presence is one of the basic services which is likely to become omnipresent in IMS (IP Multimedia Subsystem). It is the service that allows a user to be informed about the reachability, availability, and willingness of communication of another user. The fl...

Naringenin (NGN) exhibits anti-inflammatory and antioxidant activities, but it remains undetermined its topical actions against ultraviolet B (UVB)-induced inflammation and oxidative stress in vivo. The purpose of this study was to evaluate the physicochemical and functional antioxidant stability of NGN containing formulations, and the effects of selected NGN containing formulation on UVB irrad...

Ion mobility spectrometry (IMS) is recognized as one of the most sensitive and robust techniques for the detection of narcotics, explosives and chemical warfare agents. IMS is widely used in forensic, military and security applications. Increasing threat of terrorist attacks, the proliferation of narcotics, Chemical Weapons Convention (CWC) treaty verification as well as humanitarian de-mining ...

This paper describes a method for combining direct chemical analysis of latent fingerprints with subsequent biometric analysis within a single sample. The method described here uses ion mobility spectrometry (IMS) as a chemical detection method for explosives and narcotics trace contamination. A collection swab coated with a high-temperature adhesive has been developed to lift latent fingerprin...
