we describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. we present a new method for computing, electronic transport wave function and greens function of the disordered graphene. in this method, based on the small rectangular approximation, break up the potential barriers in to small parts. then using the f...

one of the most common signals used for achieving high range resolution in radar is stepped-frequency signals. when a target is stationary in these radars, dft (discrete fourier transform) based processing is used to attain high range resolution profile (hrrp). however, in the case of moving target, due to spreading of the echo signal spectrum, dft based processing is not optimal and decreases ...

Abstract In this work, we adapt an established model for the ‐induced fusion dynamics of synaptic vesicles and employ a lumping method to reduce its complexity. reduced system, sequential ‐binding steps are merged single releasable state, while keeping important dependence reaction rates on local concentration. We examine feasibility reduction representative stimulus train over physiologically ...

Two landuse grids were available for these catchments; one in 1995 was derived from satellite imagery and contained a relatively undifferentiated landuse classification (lumping all forest types into one category); the other in 2003 was derived from a mix of satellite imagery, ground truthing, and mapping, and better differentiated between landuse types (dividing forest types into evergreen, de...

This paper applies the lumping method, proposed by Takahashi(4], to get stationary probabilities numerically for a loss system with two types of input streams. By using the method we can evaluate numerically the effect of introducing several servers who are capable to serve both types of customers.

Modelling a finite population genetic algorithm (GA) as a Markov chain can quickly become unmanageable since the number of population states increases rapidly with the population size and search space size. One approach to resolving this issue is to “lump” similar states together, so that a tractable Markov chain can be produced. A paper by Spears and De Jong in [1] presents an algorithm that c...

Bridging systems biology and pharmacokinetics-pharmacodynamics has resulted in models that are highly complex and complicated. They usually contain large numbers of states and parameters and describe multiple input-output relationships. Based on any given data set relating to a specific input-output process, it is possible that some states of the system are either less important or have no infl...

This paper offers an approach that could be useful for diverse types of layout problems or even area allocation problems. By this approach there is no need to large number of discrete variables and only by few continues variables large-scale layout problems could be solved in polynomial time. This is resulted from dividing area into discrete and continuous dimensions. Also defining decision var...
