A modified distance-estimating algorithm DV-GNN was presented Pouches to improve the precision of indirect dis- tance measuring in wireless sensor networks, theoretical basis was analyzed, and implementing process was given.With the help of gradient neighbors, the resolving power of distance estimating was increased from effective radio range to th

In this work, we present a study about Foot Care the application of bi-temporal, large interval aerial laser scans for constructing of tree growth models and estimating site index quality based on the measured increments from the laser scans.We compared two LiDAR scans with 14 years of difference in the national park area, where most areas are unma

In Southwestern China, there exists deep river valleys and abundant rainfall, which leads to a large number of reverse-dip rock slopes.In order to investigate the evolution characteristics of toppling deformation of reverse-dip slope under the influence of rainfall, and a typical reverse-dip slope was taken as an engineering case.Firstly, the tempo

Background and Objective: Microbial protein production can resolve one of the major world challenges, i.e.lack of protein sources.Candida tropicalis growth was investigated to specify a medium to reach the highest cell proliferation and protein production.Material and Methods: Fractional factorial design and the Lockers index of signal to noise rat

Increase of axle load and wagon numbers of heavy haul train would generate larger longitudinal train impulse in the condition of shunting impact, and it would result in some dangerous problems.On the basis of draft gear dynamic modification model, the vehicle impact equation and vehicle-coupler-vehicle series model, the effect of different braking
