Key element protection of combat system is a challenging problem in modern combat. Effectively evaluating the key elements would be of great help in force deployment in crisis situations. This paper proposes a new evaluation method that combines expert evaluation, PCA (Principal Component Analysis) and TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution). Specifically, we first...
Sparse representation has been applied to visual tracking. The visual tracking models based on sparse representation use a template set as dictionary atoms to reconstruct candidate samples without considering similarity among atoms. In this paper, we present a robust tracking method based on the inverse sparse group lasso model. Our method exploits both the group structure of similar candidate samples...
The text-to-scene conversion is such a process that converts the input text into 3D scenes automatically based on the natural language processing. The scene layout is the basic research content and the key section of the text-to-scene conversion. It realizes the automatic layout through identifying the information about scene layout from the input text and relying on a large database of 3D models...
Applying semantic technologies to C2 organization is an up-to-date research direction which is used to achieve information sharing quickly and effectively for improving information service. This paper reviewed some methodological approaches about C2 organization and presented the extension PCANS (ePCANS) model, based on it, provided Language Concept Graph (LCG) based on ePCANS model to represent ontology...
At present, Checkpoint/Restart is one of the most popular fault tolerance mechanisms for large scale parallel computing. However, the time to save a global checkpoint reaches and even exceeds the mean-time-between-failures (MTBF) of the component when the performance of the system is between Peta(1015) and Exa(1018) flops, which limits the scalability of the parallel computing. In this paper, a scalable...
Symbiotic simulation systems have been proposed as a new paradigm for discrete event simulation by having simulation and physical system interact in a mutually beneficial manner. Traditional C2 decision support system is analyzed, and the idea of symbiotic simulation is introduced. Then the conceptual framework of C2 decision support system based on symbiotic simulation is proposed. Each function...
Taking the quantitative dynamic mechanical performance of MEMS device into acount, the accurate 3D geometric model of MEMS devices is very important. In this paper, the concept of virtual process was put forward; and each single process step is simulated by computer graphics at first; in this way, the whole process and typical shape changes are contained in virtual process. Next, the problems involved...
