A higher-order sandwich theory is implemented in conjunction with an equivalent mobility-based power flow progressive method to determine power flow for a sandwich configured floating raft vibration isolation system. The power spectrum changes in whole frequency range effectively when core materials’ properties change. It is also shown that the loss factors of the sandwich configured floating r...

Raft is a consensus algorithm for managing a replicated log. It produces a result equivalent to (multi-)Paxos, and it is as efficient as Paxos, but its structure is different from Paxos; this makes Raft more understandable than Paxos and also provides a better foundation for building practical systems. In order to enhance understandability, Raft separates the key elements of consensus, such as ...

The secant piled-bucket foundation (SPBF) is innovatively proposed to suit the large-capacity mainstream, which optimized from a traditional and consists of an upper pile cap lower bucket skirt. Compared with foundation, SPBF has great advantages deserves further study. In this research, bearing mode, capacity failure mode under various loads in saturated clay have been fully studied. First, sm...

In the projects of buildings and structures, in last two to twenty-five years, world practice, so-called combined pile raft foundation (CPRF) is increasingly used, for which, design calculations, it assumed that calculated load from building distributed between piles raft, allowing up 50% inclusion work (resistance) raft. As part scientific technical support [1-8] construction object, instrumen...
