Wireless sensor network (WSN) requires robust and energy efficient communication protocols to minimize the energy consumption as much as possible. However, the lifetime of sensor network reduces due to the adverse impacts caused by radio irregularity and fading in multi-hop WSN. A cluster-based scheme is proposed as a solution for this problem. The proposed(More)
Bandwidth provisioning and QoS mapping are key issues to support multimedia services such as VoIP in the emerging network technologies. The classification feature enables MPLS (Multi-protocol Label Switch) to support differentiated types of services (DiffServ) with needed QoS. The differentiated service model provides a variety of mechanisms to achieve(More)
The smart home concept brings innovation and convenience to our every day's life style at home. Without context awareness, smart home applications cannot offer services that can adapt to users¿ dynamic situations; they also fail to give preferential treatment for users¿ various preferences. Such design paradigm forces human to live in the world of machines(More)
Crotoxin (Cro), the principal neurotoxic component of Crotalus durissus terrificus, has been previously reported to have a behavioral analgesic effect in rats and mice. The present study investigated electrophysiologically the effect of Cro on pain-evoked unit discharge of neurons in thalamic parafascicular nucleus (Pf) and underlying mechanisms of its(More)
The present study investigated the inhibitory effect of cobratoxin (CTX) on pain-evoked discharge of neurons in thalamic parafascicular nucleus (Pf) of rats and analyzed some of the mechanisms involved in this effect. Intracerebroventricular injection (icv) of CTX at 0.56, 1.12 and 4.50 microg/kg resulted in a dose-dependent inhibitory effect on the(More)
In a human-centric smart space, Activities of Daily Living (ADL) analysis can provide very useful information for elder care and long-term care services. ADL is defined as an assessment of a person’s functional status. Many recent researches concentrate on designing a good Context Aware Computing System to automate the actions necessarily triggered by ADL(More)
