Multi-disciplinary virtual prototype (MDVP) based on modeling and computer simulation technology has been applied in a wide range of engineering applications, especially the design, testing and evaluation of complex products. Generally, a large set of parameters need to be optimized to improve the performance of the prototype, which comprises a number of heterogeneous models from multiple domains...
This paper focuses on a RFID-Based dynamic positioning scheme, aiming to locate an object by using a moving RFID reader and reference tags without recording any measurement data, e.g., the time of arrival (TOA) of the signal, or the received signal strength indication (RSSI). To address the problem of blindness of location path, a RFID-based positioning scheme with MATLAB GUI, is proposed based on...
Large scale data process has emerged as an important issue for concerned researchers. By reusing calculation results, the efficiency of large scale data process can be improved greatly. This paper proposes an efficient data reusing strategy based on the data warehouse tool-Hive, which works on MapReduce framework. Since the intermediate calculation results have been stored in DFS by different jobs...
To improve the hand gesture recognition accuracy based on Hu moment features, a new recognition algorithm was developed based on the fingertip structure detection. Firstly, the geometric features, the areas of skin region and the image, were designed to segment the skin region from the background in space of hue, saturation and value of brightness. Secondly, the cam point inspections were carried...
The main object of workflow description is to map business requirements quickly and accurately mapped to business process. An approach of business semantic-oriented workflow description method is proposed aiming at the current workflow description method lack of resource allocation means oriented business staff. It provides a description way that business staff familiar with through which business...
Replica is better than erasure coding when managing the redundancy of a storage system under high churn. It needs extra network communication to keep the target redundancy. By classifying the hosts into different categories of availability and placing the data replicas carefully may reduce the maintenance overhead. Considering a globe scale P2P system, the time-zoned multilayer Chord divides the hosts...
In order to achieve the virtual manufacturing (VM) technology, we need to carry out different aspects of scientific research[1]. This paper focuses on the virtual production planning in the manufacturing enterprise. The reasonableness of production planning program is evaluated by the Witness simulation software and data prediction. Finally, that will make out the balance of logistics, energy and...
The Pressure-Node Model is used in the simulation of single-phase incompressible fluid/compressible fluid system. When the pressure nodes are dense or the differential pressure is lesser between nodes, this model will cause problems, such as unbalanced flux in all the branches of one node, slow calculating, and so on so forth. This article will introduce a Liquid-Network Model that is based on random...
It is important in communication networks to use routes that are as short as possible (i.e have low stretch) while keeping routing tables small. Recent advances in compact routing show that a stretch of 3 can be achieved while maintaining a sub- linear (in the size of the network) space at each node [14]. It is also known that no routing scheme can achieve stretch less than 3 with sub-linear space...
