This work considers a multi-hop sensor network and addresses the problem of minimizing power consumption in each sensor node locally while ensuring two global (i.e., network wide) properties: (i) communication connectivity, and (ii) sensing coverage. A sensor node saves energy by suspending its sensing and communication activities according to a Markovian stochastic process. We show that a powe...

This work addresses the problem of minimizing power consumption in each sensor node locally while ensuring two global (i.e., network wide) properties: (i) communication connectivity, and (ii) sensing coverage. A sensor node saves energy by suspending its sensing and communication activities according to a Markovian stochastic process. It is shown that a power level to induce a coverage radius w...

whose distribution we may hope to be close to Gaussian. T1 can be bootstrapped (potentially with standard biascorrection and acceleration) to obtain bootstrap CIs, nonparametrically dealing with the unknown variance v1. We ran simulations with n = 800, p = 1500, X having i.i.d. Bernoulli(0.05) entries (the columns of X were then standardized to have mean 0 and variance 1), θ = σ = 10, and εi i....

conclusions in treatment of intra-articular distal radius fractures in middle-aged patients internal fixation with locking plates may be prefered to pin and plaster as the treatment of choice. results sf-36 test demonstrated a better general health (p < 0.001), mental health (p = 0.006), physical functioning (p < 0.001), social functioning (p < 0.001) and energy/fatigue (p < 0.001) in lcp group...

LTE Femtocells are designed to increase capacity and coverage especially for the indoor and cell-edge mobile users. Typically, they are deployed to offload t he macrocell users. However, due to co-location of femtocells in macrocell coverage, the co-tier and cross-tier interferences are high. Fractional Frequency Reuse mechanism (FFR) is one of the most effective femtocell interference avoidanc...

The probability-based covering algorithm (PBCA) is a new algorithm based on probability distribution. It decides, by voting, the class of the tested samples on the border of the coverage area, based on the probability of training samples. When using the original covering algorithm (CA), many tested samples that are located on the border of the coverag e cannot be classified by the spherical nei...

SS precursors are the underside reflections from the upper mantle discontinuities such as those at 410 and 660 km. They are important tools for studying the existence and characteristics of mantle discontinuities both on the global and regional scales (see Deuss, 2009 for a review). Due to their sensitivity at the midpoint between source and receiver, coverage for oceanic regions is achieved wh...

In this paper we examine the interactions of the soft-handoff thresholds with the traffic load of a CDMA cell. We assume a user distribution following a spatial homogeneous Poisson process and determine the joint probability distribution for the radii of the two cells and the minimal overlapping area which will be interpreted as the area of soft-handoff. With these values, we can obtain the opt...

We take some parts of a theoretical mobility model in two-dimension grid proposed by Greenlaw and Kantabutra to be our model. The has eight necessary factors that we commonly use mobile wireless network: sources or signal providers, the directions source can move, users devices, given which define user's movement, source's velocity, coverage, obstacles. However, include only sources, obstacles ...

Previous work has indicated a clear, consistent diurnal cycle in rainfall and cold cloudiness coverage around tropical cyclones. This cycle may have important implications for structure and intensity changes of these storms and the forecasting of such changes. The goal of this paper is to use passive and active microwave measurements from the Tropical Rainfall Measuring Mission (TRMM) Microwave...
