Pocket parks are small in size and flexible function. In the process of urbanization development China, number 
 pocket has gradually increased, but from current point o f view, there many problems construction China . This study conducts a detailed investigation on plants, sports facilities roads park by adopting method on-site park. It was found that currently have such as functional lim...

membrane-based technologies have increasingly been chosen in desalination processes, which is evidenced by the increase of large-scale plants constructed in recent years. indeed, several appropriate strategies should be considered to minimize problems faced during the construction, such as membrane system designs, area requirement, energy requirement, operation and maintenance, and environmenta...

Why should it matter how many people visit national parks? In a word: politics. Protected areas are not only physical places, reservoirs of biodiversity, and sources of ecosystem services, such as breathable air and drinkable water. They are also human political constructs, and they are under ever-increasing pressures from growing human populations and resource demands. Visitors may bring them ...

Model checking complex systems always suffers from the state explosion problem. Over the last 10 years there has been lots of researches on how to mitigate the state explosion problem. As a result, many techniques have been emerged such as absiraction, compositional reasoning, and exploiting symmetry. In line with these efforts, this paper proposes stepwise model checking which exploits hierarc...

We define model checking games for the temporal logic CTL∗ and prove their correctness. They provide a technique for using model checking interactively in a verification/specification process. Their main feature is to construct paths in a transition system stepwise. That enables them to be the basis for a local model checking algorithm with a natural notion of justification. However, this requi...

A behavior-RTL equivalence checking method based on bottom-up reasoning is presented. Behavior and RTL descriptions are converted into dependence graphs from which virtual controllers/datapaths are generated. Actual equivalence checking is based on isomorphism analysis on dependence graphs and also virtual controllers/datapaths. First equivalence classes on partial computations are extracted by...
