In order to improve the quality of Activity Recognition Chain (ARC) systems, an effective testing approach is required to evaluate the functionalities of their major components, especially for two kernel components, the segmentation and recognition components. Both of them largely utilize the machine learning algorithms to achieve the detection and recognition of activity correctly. The probabilistic...
The VORPAL finite-difference time-domain particle-in-cell simulation tool now has thermal solver capability, which we are using to model transmission lines and accelerating cavities of cryogenic SRF accelerators. This same capability can be brought to bear on room temperature problems EM and Thermal physics. Our thermal solver treats the non-linear evolution of the material properties, such as electrical...
In web services-based applications, Web applications can be composed of hundreds of web services. Hence, application system quality depends on the quality of the involved web services. When the service evolves, it may not satisfy anymore the requirements of end user (anyone who use the web service). Any change of a web service, it must be re-tested at the unit level, and re-used to form services-based...
Summary form only given. The VORPAL finite-difference time-domain particle-in-cell simulation tool has traditionally been used for accelerator, electromagnetic, and plasma simulations. Approximately two years ago, a generalized PDE (partial differential equation) capability was added to the software, and we are now developing this capability to provide multi-physics simulations capability. Our project...
