Monte Carlo simulation softwares for nuclear medicine have become fundamental tools for PET, SPECT and more recently X-Ray CT system design and prototyping. This paper proposes a method to allow the execution of GATE simulations in a shared-memory multi-core system. The work is an adaptation of a previous distributed meory model for GATE, and it is fundamentally based on the multithreaded version...
A model for credit risk was established and a new method is presented to deal with credit risk assessment problems for commercial banks based on rare event simulation. The failure probability of repaying loans of listed company is taken as the criterion to measure the level of credit risk. The rare-event concept is adopted to construct the model of credit risk identification in commercial banks, and...
In DDDAMS paradigm, the fidelity of a complex simulation model adapts to available computational resources by incorporating dynamic data into the executing model, which then steers the measurement process for selective data update. Real-time inferencing for a large-scale system may involve hundreds of sensors for various quantity of interests, which makes it a challenging task considering limited...
At present, city operations and development forms an important theme in research on city science. Many scholars study the city lifeline situation in different ways in order to evaluate the city's ability for sustainable development and eventually guide the structural transformation of city's economy and society in China. In our research, 11 different kinds of methods as to city operations and development...
