The Reliability Information Analysis Center (RIAC), under contract to the Defense Technical Information Center (DTIC), is developing and implementing a Web-Accessible Repository of Physics-based Models (WARP) database and website to centrally organize and make available information and data on physics-based models. In addition to providing access to available Physics-of-Failure (PoF) model information...
In this paper, we investigate a real-time estimation system in HLA-based simulation systems. The use case and architecture of the system are analyzed. The main parts of the system, including the evaluation agent, the databases and the web-based result display systems are introduced. Towards the evaluation agent, the interface relationships are depicted. Then the structure and principle of evaluation...
PHP is one of the leading Web development languages, however, the development model of existing PHP organizes without a structure, which mixes the code of data access, the processing of business logic , and Web presentation layer together, as a relult, it brought about many problems in the Web applications , meanwhile, it could not meet the rapid development of Web apply any more. In this paper, a...
Data(base) reverse engineering is the process through which the missing technical and/or semantic schemas of a database (or, equivalently, of a set of files) are reconstructed. If carefully performed, this process allows legacy databases to be safely maintained, extended, migrated to modern platforms or merged with other, possibly heterogeneous, databases. Although this process is mostly pertinent...
Bayesian networks (BNs) are probabilistic graphical models that are widely used for building diagnosis- and decision-support expert systems. The construction of BNs with the help of human experts is a difficult and time consuming task, which is prone to errors and omissions especially when the problems are very complicated. Learning the structure of a Bayesian network model and causal relations from...
"Work time management - WTM" is an application presenting an example of usage popular and open Web technologies accessible on the Internet. Web technologies used in the application are divided in two main groups. Client side technologies, this is cascading style sheets - CSS, script language - Javascript and asynchronous Javascript - AJAX with additional libraries like jQuery and Prototype,...
With the development and popularization of Internet, distance education has already entered the stage based on Web. Due to the shortcomings of traditional methods in developing Web application, the MVC (model-view-controller) pattern is introduced. The separation of logic programming from interface design is effectively archived by the three kinds of technology correlated with Java: JSP, Servlet and...
This article analyzes the current Web graphic processing technique, and then it puts forward a new model of object grouping database and technology of rapid graphic refreshment based on the incremental data. Later on it discusses collaborative graphic editing technology to organize GIS data more effectively and improve graphics interaction processing efficiency under network environment.
In order to realization electronic parts product appearance quality detection control, one kind of processor based on the intelligent knowledge automatic extraction and system intelligence modeling was presented. In the processor, wavelet-fuzzy technique and neural network technique are combined. Uses the fuzzy wavelet extraction image feature, and wavelet function is used as fuzzy membership function...
