We study the mechanism design problem of a social planner for locating two facilities on line interval [0, 1], where set n strategic agents report their locations and determines facilities. consider requirement minimum distance 0 ≤ d 1 between Given are heterogeneous, we model cost/utility an agent as sum his distances to both In heterogeneous two-facility location game minimize cost, show that...

In this correspondence, we study the physical layer security in a stochastic unmanned aerial vehicles (UAVs) network from network-wide perspective, where locations of UAVs are modeled as Mat$\acute{\text{e}}$rn hard-core point process (MHCPP) to characterize minimum safety distance between UAVs, and users eavesdroppers Poisson cluster process, respectively. adopt zero-forcing precoding serve mu...

The study aims to investigate the use of panchromatic (PAN) satellite image data for flood hazard assessment with an aid of various digital image processing techniques. Two SPOT PAN satellite images covering part of the Nile River in Egypt were used to delineate the flood extent during the years 1997 and 1998 (before and after a high flood). Three classification techniques, including the contex...
