In the past two decades, step-indexed logical relations and separation logics have both come to play a major role in semantics verification research. More recently, they been married together form of like VST, iCAP, Iris, which provide powerful tools for (among other things) building semantic models richly typed languages Rust. these logics, propositions are given using model, reasoning is refl...

Thanks to the increased awareness that web-born contents are worth preserving and to improved digitization techniques, web archives have grown in number and size. To unfol...

Increasing population, total economic volume, and human consumption levels have resulted in problems of resource shortages, climate change, ozone layer depletion, land regression, and deteriorating environmental pollution. Printing and related industries constitute one of the major sources of environmental pollution due to heavy energy and resource (materials) use. Therefore, there is a need to...

Power saving is an important factor in Mobile Ad hoc Networks, because most of the equipment in MANETs are battery powered. So we have to reduce the power consumption of each and every node. There are several methods to reduce the power consumption of nodes. An effective method is sending the packets with optimum power. In this paper, we propose an energy efficient power aware routing (EPAR) pr...
