One dimensional SIMD array which is PIM-based data parallel computer architectural has been proposed for multimedia processing application. This paper describes the implementation of a controller for one dimensional SIMD array. The main components of the controller and the instruction format are presented. PE array control is introduced in detail. Finally, the results of simulation are given to show...
This paper compares two different approaches, followed by our research group, to efficiently run NEPs on parallel platforms, as general and transparent as possible. The vague results of jNEP (our multithreaded Java simulator for multicore desktop computers) suggests the use of massively parallel platforms (clusters of computers). The good results obtained show the scalability and viability of this...
With the development of computer science, large-scale distributed simulation is becoming mature. As an outstanding network simulation software, OPNET can simulate on single machine. In order to be one of large-scale distributed simulation,it need to be controlled. HLA can construct new complicated simulation applications with the reusable simulation module conveniently according to communication simulation...
This paper is a study of the “Character and Object Repetition” problem in crowded scenes. A detailed technique is presented in comparison to alternative previous solutions from different researchers.
Testability is a significant design feature for system, which has gong through five stages such as External Test, BIT (Build-in Test), Intelligent BIT, Comprehensive Diagnosis and PHM (Prognostics and Health Management), has greatly improved the maintainability, reliability and availability of the modern weapons especially in electronic systems [1]. Meanwhile, in the process of the researches on systems...
The experimental simulation system is visually modeled and designed with UML, and realized on DOTNET development platform. Practice shows that the use of Unified Modeling Language not only can have good system scalability and reusability, but also can improve the efficiency of the system.
Fault tolerance is a central issue in the design and implementation of interconnection networks for large parallel systems. Connection probability of a network is a good network fault tolerance measure. For a mesh of given size and node failure probability, the gap between the known upper and lower bounds on the connection probability is often very large. In this paper we design algorithms to estimate...
Based on the heralded pair-coherent states sources, the Vacuum+Weak decoy state protocol focused on BB84 is presented. Combining the passive decoy state method and the active decoy state method, we use the triggered and nontriggered components to estimate the fraction of single-photon counts and quantum bit-error rate of single-photon and to generate the secure key. From the simulation results of...
Since Gode and Sunder had introduced zero intelligence with budget constraint (ZI-C) agents in the double auction experiments, there has much controversy in whether the pure market discipline in ZI-C system has the ability to let the transaction prices converge to the competitive equilibrium. In this paper, we introduce a probability model to simulate the ZI experiences and try to gauge the power...
In this paper, snoopy cache coherence protocols with update strategy have been studied, since description of protocols is apparently different in references, so we offer a common description in order to show simplicity and comparability protocols. Evaluating of protocols is in simulation level By limes simulator tools. Limes includes dragon protocol [1], that we added WTU and firefly protocols to...
In the area of computer game, Amazons game is a relatively new one whose rules stand between the game of Chess and Go. Its move rule is simple but apt to generate tremendous move branches. Based on the UCT searching algorithm, this paper presents an idea that the whole process of Amazons game can be divided into three phases, which are the Opening, Middle game and Endgame, then different strategies...
The super codes of the first order Reed-Muller code are widely used in the practical wireless communication systems, such as WCDMA and LTE. However, the super codes are usually obtained by exhaustive computer search, which involves huge computational cost. Therefore a systematic algorithm to construct the super codes beyond exhaustive computer search has been expected for long time. In this paper,...
The multi-source information processing board is given based on PCI-E bus in the paper, which is often used to collect and process the output data of multi-source photoelectric sensor in real time. This paper describes the process of the system development in detail, gives the program of algorithm simulation used to realize the information fusion and image processing, especially introduces the design...
Cooperation in social dilemma games has been shown to be favored through evolution by various means such as topological heterogeneities or high benefit to cost ratio. As an extension to the previous studies with pure strategies, we incorporate the mixed strategies in the evolutionary dynamics and provide a higher resolution for the quantitative comparison of different scenarios with varying network...
This paper presents the criteria and performance indicators used for a structured analysis of two evaluation methods for the applied capabilities of software usage: computer based exam and group project assignment. The results of the application of this structured analysis are presented and discussed.
In this paper we present a remote utility metering system based on ZigBee used to collect data from residential electricity, gas and water meters. In order to reduce the use of network resources and to evaluate the sensor network performance, a simulation study was carried out with two types of data related to electronic and non electronic metering devices. The study was conducted using a simulator...
There has been enormous interest about Covering Location Problem (CLP) among both academicians and practitioners around the world. Applications of CLP range from locating fire stations to telecommunications. This paper deals with a special case of CLP where travel times are fuzzy variables. In addition, it has been assumed that the variable cost of locating facilities is a function of the distance...
Numerical simulation models of high pressure common rail fuel system were established, the influences of nozzle hole diameter and nozzle hole number on injection rate were studied by means of these models. The research results show that software simulation technology is an effective method for simulation calculation and optimization design for high pressure common rail fuel system(HPCRFS) and comparison...
Based on the theory and method of system dynamics, we establish a China's SO2 emission trading policy model which includes SO2 pollution subsystem, policy implementation subsystem and policy effect of evaluation subsystem, and test the model from historical data and parameter sensitivity. And then, using Vensim software, annual SO2 emissions and policy effect of SO2 emission trading are simulated...
Litchi fruit mechanized flexible picking could effectively solve the issue of the labor shortage at harvest time, and achieve high efficiency of harvesting fruit without injury, which have an important prospects of development and application. This paper designed a PP-RRR manipulator with S-joints DOF. By applying CAD graphic method, analyzed the structure size of manipulator in the height of 1-3...
