Some ad hoc protocols allow the discovery and/or storage of multiple routes to the same destination node. The selection of the path to utilize is commonly based on the criterion of the minimum number of hops. However, other strategies could be more appropriate to improve the network performance. In this sense, this paper proposes the criterion based on the estimation of the Mean Residual Path L...

The introduction of unemployment insurance savings accounts (UISA) in Chile in October 2002 brought in more comprehensive unemployment protection while decreasing the opportunity costs of job change. Being the first to empirically investigate the effect of UISA on employment duration, this paper examines (i) whether the introduction of UISA affected employment duration among formal private sect...

In this paper we present a new model for the lifetime of wireless sensor networks used for sea water communications. The new model for power communications takes into consideration parameters such as power consumption for the active mode, power consumption for the sleep mode, power consumption for the transient mode, transmission period, transient mode duration, sleep mode duration, and active ...

OBJECTIVES To determine the effect of structured exercise on overall mobility in people after hip fracture. To explore associations between trial-level characteristics and overall mobility. DESIGN Systematic review, meta-analysis and meta-regression. DATA SOURCES MEDLINE, EMBASE, CINAHL, the Cochrane Central Register of Controlled Trials, the Cochrane Bone, Joint and Muscle Trauma Group Spe...

Objective The aim of this study is to determine the presence kinesiophobia in patients with ankylosing spondylitis (AS) and examine factors affecting kinesiophobia. Materials methods Sixty AS participated study. Kinesiophobia was evaluated using Tampa Scale for (TSK). Disease activity assessed Bath Activity Index (BASDAI) Score C-reactive protein (ASDAS-CRP), functional status Functional (BASFI...

in order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the college of agriculture, shiraz university, shiraz, iran during 2010 and 2011 growing seasons. two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included...

We investigate the problem of energy-efficient broadcast routing over wireless static adhoc network where host mobility is not involved. We define the lifetime of a network as the duration of time until the first node failure due to battery depletion. We provide a globally optimal solution to the problem of maximizing a static network lifetime through a graph theoretic approach. We also provide...

Realistic mobility models can demonstrate more precise evaluation results because their parameters are closer to the reality. In this paper a realistic Fuzzy Mobility Model has been proposed. This model has rules which are changeable depending on nodes and environmental conditions. It seems that this model is more complete than other mobility models.After simulation, it was found out that not o...
