Directional brightness temperature (DBT) plays an important role in surface energy balance and urban climate. How to determinate the components' proportion efficiently is one of the key factors to accurate simulation of DBT. Usually, determining the proportion of each component in the sensor's field of view (FOV) uses the radiosity method. This approach is more complicated and highly accurate, however,...
PSO has emerged as a powerful heuristic technique for determining the global optimal solution of nonlinear optimization problems. Like all other evolutionary algorithms (EAs) it is also population based method. However, due to the inherent nature of PSO, it is desirable to parallelize it so as to get a better performance. In this paper, three versions of parallel PSO are presented. They are encoded...
In this paper, a multi-stage stochastic programming model is constructed, for the dynamic asset allocation with the transaction cost constraints. In the mean time in order to improve the performance, the Conditional Value-at-Risk as the risk measure, which is a very important concept in the modern risk management field, is also contained. However, with the increase of the number of scenarios, the...
The cellular Potts model (CPM) has been widely used for biological simulations. However, most of current implementations are either sequential or approximate, which cannot be used for large scale complex 3D simulation. In this paper we present a hybrid parallel framework for CPM simulations. The time-consuming partial differential equation (PDE) solving, cell division, and cell reaction operation...
Improving plant structure is pivotal for increasing the potential yield of crops. The aim of this paper was to evaluate the influence of leaf angle and leaf area index (LAI) on light interception efficiency and capacity of biomass production of rice using 3-D models. A group of virtual plant types of rice, with different combinations of leaf angles, was designed based on the 3-D data of a real rice...
We present a tool for parallel enumerative LTL model-checking and reachability analysis. The tool brings model checking to high-powered multi-core systems, as well as high-performance clusters. Boasting pluggable modelling language framework, it is possible to leverage the available parallel algorithms for multiple problem domains, by using suitable input language.
We present a DEVS and Cell-DEVS simulation system based on Microsoftpsilas .NET Remoting, an execution framework for Windows programs. Remoting is the process of programs interacting across different processes or machines. The numerous remoting services in .NET provide the ability to invoke objects that exist anywhere on the network. We modified PCD++ (a parallel DEVS and Cell-DEVS simulation tool...
