When using the original method to evaluate the operational effectiveness of electronic warfare equipment, due to the influence of too many states involved, it is impossible to build the combat simulation model of electronic warfare equipment, and the calculation results of unit damage probability in the range of 1000-3000 meters in the configuration area are inaccurate. Therefore, an operational effectiveness evaluation of electronic warfare equipment based on improved fruit fly algorithm is proposed method. The operational simulation model of EW equipment is established, which mainly includes battlefield environment model, entity model and combat action model. Using the method of decomposing and evaluating targets, the index set is initially drawn up, and the initial index set is compared, selected, and de-correlated. Through the screening index, the operational effectiveness evaluation model of electronic warfare equipment is constructed to realize the operational effectiveness evaluation of electronic warfare equipment. The original method is compared with this method, and the experimental results prove that the accuracy of the calculation result of the damage probability of the soldier group of the method is higher than that of the original method, and the performance is improved.

With the development of Internet technology, display experiments seem to be gradually replaced by virtual experiments. However, in the actual teaching, it is found that the display experiment plays an irreplaceable role in cultivating ability of student to maintain and innovate. A new idea of management of display laboratory starting from the relationship between entity model and virtual model based on internet of things technology was presented in this paper, in order to solve the difficult problems that have long puzzled the development of laboratory. It lays a foundation for the establishment of a “student-centered” basic teaching environment

Single or small batch insulation cup was analyzed and improved based on reverse design and rapid prototyping technology. According to the structural characteristics of the selected insulation cup, the digital information of the model was accessed by hand-held laser scanner. Combined with the idea of reverse design, the sample space surface and entity model were reconstructed based on Imageware and Creo software. The sample entity model was reconstructed accurately by rapid prototyping technology. The comprehensive application of reverse design and rapid prototyping technology can improve the iterative efficiency of single or small batch cup, which has a good reference value for the development of single or small batch product.

By the demand and feasibility analysis of MOOC, this article adopts B/S structure including J2EE, Flex, Reds video server technology and WebService to design and realized a learning platform for online study and teaching interaction. The platform design adopts MVC mode and takes three lightweight framework of SSH2 in three-layer structure. The part of video processing adopts video server technology and designs the data model according to entity model and E-R graph. Later test analysis shows that our scheme achieves expected object in function and performance, which also ensures the proposed performance standards of overall platform.

The hydrodynamic behaviours of the perfusion process (cleaning) of the liver vessels before the operation was studied. A straight and a curved First-Class vessel entity model with foreign matter and the control equations of turbulent liquid in the vessels were established. With the physical parameters of a medical perfusion liquid measured, an estimation method of perfusion parameters was proposed. The simulation was performed by changing technical parameters of the perfusion. It is based on the control equations of turbulent liquid in the vessels and the preliminary calculated results using the vessel models. The simulation was performed by changing technical parameters of the perfusion. It is based on the control equations of turbulent liquid in the vessels and the preliminary calculated results using the vessel models. With the increasing perfusion velocities, the pressure and the velocity field increased in the two types of the vessel models. The negative trans-mural pressure and recirculation zones appeared and located on the foreign matter. Because of the influence of the vessel shape, the fluid dynamics behaviours in the curved vessel model are more complicated than those in the straight vessel model.

The Daguerreobase project has succeeded in developing a proposal for standards and a set of multilingual thesauri to describe the daguerreotype objects and their image content. The Daguerreobase consortium developed an entity and metadata model which is compatible with international standards. From the model, standards for the description of daguerreotype objects and content have been derived. The entity model and the standards are implemented in the new Daguerreobase portal which will be available online from November 2013. The consortium believes that the establishment, adoption and dissemination of these standards through the renewed Daguerreobase portal will increase the level of description of daguerreotypes and enhance access to a little known photographic medium.

This paper proposed a new computer aided parametric design (CAPD) method by which a visual and three-dimensional entity model of crushing jaw plate and tooth-shape in a jaw crusher has been achieved based on a Pro/E's function of entity model creating. Relevant explanations have particularly been present for screening of specific parameters and performing procedures of creating an entity model required by parametric design of crushing jaw plate and tooth-shape in a jaw crusher. This kind of designing method can lay a foundation of computer aided parameteric design for designing a reasonable, accurate and appropriate crushing jaw plate and tooth-shape in a jaw crusher.

Aims at the needs of the culturing fire commanders' capabilities of the anti-ship engagement, the scene visualization, in the naval-gun fire-training system, was designed using VP (Multigen VegaPrime) and VC++, etc. Firstly, based on the construction of the warship three-dimensional entity model, the scene is simulated by application configuration files generated using VP and simulation program in VC++.net environment, which this is the simulation of the process from the enemy observation, firing order to the impact generation. Secondly, the database is used to record the process of the fire-training. Thirdly, the visualization, about the process of naval-gun anti-ship engagement command training, is completed, and is providing realistic visual information to commanders. Fourthly, the training process, result vision, and self-evaluation criteria for commanders are provided. Lastly, the results of the simulation show that the system can provide the targeted training environment, and make the simulation training closer to the actual combat.

Nominal entity recognition is a fundamental task in natural language processing. Semantic role labeling views a sentence as a predicate-arguments structure, which provides an alternative perspective for the boundary detection and type recognition of nominal entity. In this paper, we propose a nominal entity recognition method with semantic role labeling. First, a Maximum Entropy (ME) model is trained on unlabeled data to address the data sparse problem in acquiring the preferences for each pair of predicate and argument. Then, use the information of semantic role labeling as features in a high quality nominal entity model. The experiments on ACE 2004 Chinese data show that the proposed method improves the performance of the high quality nominal entity recognizer, and achieves higher accuracy and recall rate.

Simulation system of automatic underwater vehicle (AUV) is very important in the whole R&D (research and development) process because of the complexity and uncertainty of the real ocean environment. Accordingly, the six freedom motion simulation system is presented, which was established by Visual C++. Secondly, establishing AUV entity model in Multigen Creator and putting it into the vision simulation system that made by Vega. At last, combining two simulation systems into an integrity one. The integrity simulation system performed well in test.

The individuals in the society form a non-imitable complex co-operation network, behave unpredictably. Fate raises or abandons nations in the course of history. Looking in the details, many behaviour patterns can be identified, global fate formed by the aggregate of the individual stories. By the non emotional behaviour model based on a simple entity model quite complex happenings can be simulated similarly to the reality. A model without emotions produces similar behaviour like individuals in the emotion interweaved reality.
