Laser infrared Detection and Ranging (LiDAR) has become one competitive remote sensing (RS) and photogrammetry technique. Extracting rivers’ distribution from LiDAR’s point cloud is one of its important research directions. But traditional methods are not completely suitable for the ranging data of LiDAR. Novel algorithm with profile factor as the kernel circle is proposed for rivers’ automatic...

Sensing coverage is a critical issue in sensor network deployments. We propose a novel scheme to maintain the sensing coverage in sensor networks, which we call CASS (Coverage-Aware Self-Scheduling). Different from the existing work on coverage maintenance, CASS probabilistically schedules a sensor’s sensing activities according to the sensor’s contribution to the sensing coverage. CASS is desi...

The proliferation of sensor networks, mobile and pervasive computing has provided the technological push for a new class of participatory-sensing applications, based on sensing and aggregating usergenerated content, and transforming it into knowledge. However, given the power and value of both the raw data and the derived knowledge, to ensure that the generators are commensurate beneficiaries, ...

In nature, microorganisms must often cope with hostile environmental conditions. To do so they have developed sophisticated cooperative behavior and intricate communication capabilities, such as: direct cell-cell physical interactions via extra-membrane polymers, collective production of extracellular "wetting" uid for movement on hard surfaces, long range chemical signal-ing such as quorum sen...

In nature, bacterial colonies must often cope with hostile environmental conditions. To do so they have developed sophisticated cooperative behaviour and intricate communication capabilities, such as direct cell ± cell physical interactions via extra-membrane polymers, collective production of extracellular `wetting’ fluid for movement on hard surfaces, longrange chemical signalling such as quo...

We propose a novel fast iterative thresholding algorithm for image compressive sampling (CS) recovery using three existing denoisers—i.e., TV (total variation), wavelet, and BM3D (block-matching and 3D filtering) denoisers. Through the use of the recently introduced plug-and-play prior approach, we turn these denoisers into CS solvers. Thus, our method can jointly utilize the global and nonloca...

We find the generating function of self-avoiding walks and trails on a semi-regular lattice called the 3.122 lattice in terms of the generating functions of simple graphs, such as self-avoiding walks, polygons and tadpole graphs on the hexagonal lattice. Since the growth constant for these graphs is known on the hexagonal lattice we can find the growth constant for both walks and trails on the ...
