The representation form of most signals in practice is non-stationary signal, and the main analysis methods for these signals are centralized in the field of time frequency (or time scale), and a series of results have been acquired. A reversible transformation method based on time sequence bit is proposed from another angle, and this method can be used to analyze non-stationary wide-band noise...

This work proposes and studies the properties of a hybrid sampling scheme that mixes independent uniform node sampling and random walk (RW)-based crawling. We show that our sampling method combines the strengths of both uniform and RW sampling while minimizing their drawbacks. In particular, our method increases the spectral gap of the random walk, and hence, accelerates convergence to the stat...

We present a new architecture for reversible NLP. Separate parsing and generation grammars are constructed from the underlying application's semantic model and knowledge base. By having two grammars we are free to use process-specific representations and control techniques, thereby permitting highly efficient processing. The single semantic source ensures the parsimony of development and matche...

posterior reversible encephalopathy syndrome (pres) is associated with various clinical manifestations such as headache, blurred vision, confusion and tonic-clonic convulsion. some of the predisposing factors for pres include hypertensive encephalopathy, preeclampsia and eclampsia, lupus erythematosus, thrombotic thrombocytopenic purpura and long-term use of immunosuppressive drugs. this condit...

various synthesis methods have been proposed in the literature for reversible and quantum logic circuits. however, there are few algorithms to optimize an existing circuit with multiple constraints simultaneously. in this paper, some heuristics in genetic algorithms (ga) to optimize a given circuit in terms of quantum cost, number of gates, location of garbage outputs, and delay, are proposed. ...

the effect of membrane molecular weight cut off (mwco) at three levels (10, 20 & 50 kd) on dynamic behavior of permeate flux (jp), hydraulic resistances (total hydraulic resistance, rt; reversible fouling resistance, rrf; irreversible fouling resistance, rif and membrane hydraulic resistance, rm) and milk solutes rejection (protein, rp; fat, rf; lactose, rl; minerals, rm and total solids, r...

The reaction between disulfides and phosphines generates a reversible disulfide metathesis process.

Among their many uses, growth processes have been used for constructing reliable networks from unreliable components (Moore and Shannon, 1956) and deriving complexity bounds of various families of functions (Valiant, 1984). Hence, analyzing such processes is an important and challenging problem. In this thesis we parameterize a growth process by its initial conditions and characterize it by the...
