Traffic retention is an important factor of intelligent transportation system, which can vividly reflect current state of the road. Accurate estimation of traffic retention can provide support for the dynamic allocation of the traffic signal, thus alleviating the problem of urban traffic congestion. The traditional method can only estimate the long-term or red light traffic retention according to...
Train cruising movement simulation module is an important part of high-speed train moving simulation system. According to the actual cruising movement characteristics of high-speed train, it is very important to design high-speed train cruising movement simulation algorithm to improve the calculation accuracy of train moving simulation system. Based on the conditions and the characteristics of high-speed...
We present the simulation results comparing the upset sensitivity of different types of the majority voters. We conducted the SPICE-level simulations by means of the proposed technique that provides layout-aware analysis taking into account diffusion and circuit effects. The calibration of the model parameters was provided by the analysis of experimental SEU cross section and sensitivity maps of 6T-cell...
Scientific simulations on high performance computing (HPC) platforms generate large quantities of data. To bridge the widening gap between compute and I/O, and enable data to be more efficiently stored and analyzed, simulation outputs need to be refactored, reduced, and appropriately mapped to storage tiers. However, a systematic solution to support these steps has been lacking on the current HPC...
Modeling and Simulation (M&S) has become an essential tool in the development, testing and verification of operational software in a complex multi-domain, multi-threaded heterogeneous system of systems environment. The complex systems of today encompass mix of hardware sub-systems (with varying degree of capabilities), software environments (comprising a plethora of development environments, operating...
Verifying attacks against cyber physical systems can be a costly and time-consuming process. By using a simulated environment, attacks can be verified quickly and accurately. By combining the simulation of a cyber physical system with a hybrid attack graph, the effects of a series of exploits can be accurately analysed. Furthermore, the use of a simulated environment to verify attacks may uncover...
Applying Flexsim system simulation software to build the simulation model of logistics sorting system. Before the introduction of automatic sorting equipment and technology in the sorting system, through the establishment of the Flexsim simulation model to simulate, analyze and evaluate the design scheme.
Discriminating Distributed Denial of Service (DDoS) from Flash Crowds (FC) is a tough and challenging problem, because there are many similarities between each other existed in network layer. In this paper, according to an extensive analysis of user traffic behavior of DDoS and FC, it can be found that some traffic abnormalities are existed between Bots and legitimate users. So a behavior-based method...
Distribution of bleach and chlorine rice makes some people uneasy because it is dangerous to health. The author conducted a simulation for implemantation the method of Principal Component Analysis to detect bleach and chlorine on rice with Matlab R2013a. This study focuses on the shape, texture, color, and position Pandanwangi, Rojolele, and Setra Ramos Rice intact. The result is an Euclidean value...
In this paper, a supply chain simulation testbed for the semiconductor industry is proposed. We start by identifying requirements for such reference datasets, and then we identify the main building blocks. The nodes of the supply chain that represent semiconductor wafer fabrication facilities (wafer fabs) are built on a simulation model from the measurement and improvement of manufacturing capacity...
Data acquisition systems for large-scale high-energy physics experiments have to handle hundreds of gigabytes per second of data, and are typically implemented as specialized data centers that connect a very large number of front-end electronics devices to an event detection and storage system. The design of such systems is often based on many assumptions, small-scale experiments and a substantial...
This research focuses on improving business process worked under workflow simulation. In the business process, there are several properties to be considered such as person, cost, time. The current workflow simulation cannot combine these properties to simulate the situation for business decision making. In this paper, the improving business workflow simulation is proposed by adding the business properties...
This paper discusses simulation design and analysis for Silicon Carbide (SiC) manufacturing operations management at New York Power Electronics Manufacturing Consortium (PEMC) facility. Prior work has addressed the development of manufacturing system simulation as the decision support to solve the strategic equipment portfolio selection problem for the SiC fab design [1]. As we move into the phase...
The article deals with a general simulation model which has been created to analyse capacity of single-lane roundabouts. The simulation model is created in Witness and all input data that must be provided by users are defined via a web application which has been programmed to communicate with the general simulation model. The web application also presents some results of simulation experiments; the...
Cloud Computing allows users to control substantial computing power for complex data processing, generating huge and complex data. However, the virtual resources requested by users are rarely utilized to their full capacities. To mitigate this, providers often perform over-commitment to maximize profit, which can result in node overloading and consequent task eviction. This paper presents a novel...

Credibility of science is fundamentally due to the strenuous efforts made to verify the general consistency among relevant facts, theories, applications, research methodologies, etc. and scientific method which emphasizes the significance of continuously building and testing hypotheses has withstood the test of time as a successful methodology of acquiring a body of knowledge, we can rely on, at least...
In this paper the adaptive mesh model is studied. First we introduce the 3 subdivision method which is already exist. Second, in order to make the simulation result more realistic and reasonable, we extend the traditional scheme and apply two different subdivision schemes on the triangular mesh. At last, a new mesh coarsening method is proposed, with the help of this method, we build a extended adaptive...
