A large number of instability cases and laboratory tests expansive soil slopes show that its shallow layer destruction happens because the insufficient shear strength under usual action low stress repeated dry-wet cycles. We can obtain nonlinear distribution law fitted by generalized power function based on a series considering construct numerical model FISH, to realize dynamic with vertical st...

A method to calculate the elastic shakedown limit of transportation systems (e.g. pavements and railways) supported by geogrid reinforced soils is presented. For first time, lower-bound theory combined with a strength-based simulation approach, resulting in rapid quantify benefit geogrids on limit. It allows decoupling stress generation calculations, meaning it straightforward implement, requir...

Especially scenarios like public safety or battle field require reliable Multicast (voice) communication. There are different ways to choose and maintain the groups of receivers. One alternative for certain use cases, especially for areas of danger, is Geocast. Using Geocast, a receiver is defined by its geographic position. Especially for mobile ad hoc networks (MANETs) there are several Geoca...
