We present XPDL, a modular, extensible platform description language for heterogeneous multicore systems and clusters. XPDL specifications provide platform metadata about hardware and installed system software that are relevant for the adaptive static and dynamic optimization of application programs and system settings for improved performance and energy efficiency. XPDL is based on XML and uses hyperlinks...
In this paper, we study the optimal strategies for a dual-channel retailer, who sells a product through both a traditional channel and an online channel. We investigate how the changes of the degree of customer acceptance of the online channel and the traditional channel inconvenience affect the strategies of the two channels under two different scenarios: Nash competition and channel integration...
Spatial Crowdsourcing (SC) nowadays has become a popular research topic studying how to outsource a set of spatial-temporal tasks to workers at specific locations. However, there exists a significant security concern: existing location privacy techniques are not applicable to SC. In this paper, we focus on protecting the worker location privacy against the semi-honest adversaries model while preserving...
This paper realizes a 3D reconstruction system with Kinect, which can rebuild high-level, geometrically accurate 3D models in real-time with texture feature. Now the data formats, such as .obj, .stl, .ply etc are supported in the system, which can be directly applied in Maya, CAD and other 3D animation modeling software. The implementation of the system in our paper only requires a low-cost Kinect,...
In view of the current problems in credit evaluation systems provided by C2C E-commerce, this paper analyzes the three main aspects that influence the seller's credit, and then build a new seller credit evaluation index system. On the basis of this, a multi-index linguistic evaluation method based on linguistic assessment information is proposed using LWD operator and LOWA operator. Finally, an example...
To solve the problem of grid resource allocation for tasks, an allocation algorithm based on improved particle swarm optimization was proposed. This algorithm leaded the cross operation, variation operation and select operation of the GA to the Particle Swarm Optimization Algorithm, it effectively overcame the inherent flaw of getting local optimal value by particle swarm algorithm and find the global...
Fractional-order systems, because of its long-memory nature. have been used increasingly to model natural phenomena. However, Computational difficulties of the fractional-order calculus have delayed application of fractional-order systems in engineering. For this purpose, after deriving the fractional-order integral matrix of the Haar wavelet we present a method for analysis of the fractional-order...
This paper constructed a colored time Petri net model with inhibitor arcs for the data control and transmission in inkjet printing system. The Petri net is based on the basic and some extended Petri nets, combining with the characteristic of control system. Through establishing the Petri net model for the traditional inkjet printing system, analyzing the bottleneck of the data transmission speed,...
Most UAV flight control system simulation was used for evaluating the quality of UAV and designing it, however, the results failed to conform to actual flight laws. According to the need of UAV simulator in actually, a new way which was convenient for engineering computing and appropriated for simulation training was built for simulating flight control system. With the actual flight figures, flight...
