Obesity in middle and old age predicts mobility limitation; however, the cumulative effect of overweight and/or obesity over the adult life course is unknown. The association between overweight and/or obesity in young, middle, and late adulthood and its cumulative effect on incident mobility limitation was examined among community-dwelling US adults aged 70-79 years at baseline (1997-1998) in t...
The studied area is a small portion of Sanandaj – Sirjan zone. Metasomatism at the contact of intrusive body studied and penetration of Al-rich rocks caused tourmalinization to stratiform tourmalinite in pelitic hornfels. In addition, hydrothermal fluids crystallized tourmaline nodules in monzogranite surface. The Fe/ (Fe + Mg) ratio in varied between 0.4-0.76 in stratiform tourmaline and 0.83-...
BACKGROUND Theoretical definitions of sarcopenia traditionally emphasize age-related loss of muscle strength; however, most analyses of the association between strength and mobility examine strength at a single time point. This study sought to identify sex-specific cutpoints for muscle strength and power (at one time point) and 3-year changes in strength and power that would maximize prediction...
Fuzzy Inference-based Super Peer Selection for a Practical Double-layered Mobile Peer-to-peer System
Mobile ad hoc networks have received increasing attention as mobile technology advances and more applications are developed. Mobile peerto-peer (P2P) systems are becoming useful in mobile network applications where installation of infrastructure may be difficult or even infeasible. To realize a mobile P2P system, the double-layered mobile P2P systems that consider both the mobility and energy s...
A temporary collection of wireless mobile nodes in decentralized manner is known as Mobile Ad hoc Network (MANET). In a hostile environment of MANET, security is the primary concern to achieve protected communication between mobile nodes. A number of nontrivial challenges to security designs mandate the demand of building multi-fence security solutions that achieve both extended protection and ...
Redistributive taxation and education subsidies are common policies intended to foster education attendance of poor children. However, this paper shows that in an intergenerational framework, these policies can raise social mobility only for some investment situations but not in general. I also study the impact of both policies on the aggregate skill ratio and inequality. While redistributive t...
In this paper, the performance of routing protocols DSDV, OLSR and AODV using performance metrics like Packet Delivery Ratio, Average End to End delay, Packet Loss Ratio and Average Throughput within Vehicular ad hoc networks for CBR applications over UDP connection has been analyzed. Network Simulator (NS-3.19) along with mobility model generated through Simulation of Urban Mobility (SUMO) too...
13 BSTRACT Mobile Ad hoc Networks are infrastructure less networks. Nodes themselves do routing and forwarding functions. Topology changes due to node movement. Frequent changes in topology leads to more route breaks. This in turn leads to reduction in Packet delivery Ratio (PDR). It is desired that routing protocols should select stable paths i.e. which are less likely to break. In this work, ...
In hierarchical SIP networks, paging is performed to reduce location update signaling cost for mobility management. However, the cost efficiency largely depends on each mobile node’s session-to-mobility-ratio (SMR), which is defined as a ratio of the session arrival rate to the movement rate. In this paper, we propose the adaptive mobility management scheme that can determine the policy regardi...
