The enormous increase in data has led to the next grand challenge in computing: the big data problem-that is, the practice of collecting complex datasets so large that they're difficult to store, process, and interpret manually or using traditional data management applications. This column discusses the role of modeling and simulation science in the era of big data applications. Modeling and simulation...
Predicting the application behavior such as its resource utilization in a new hardware machine is becoming an urgent issue as the increasing number of servers with various configurations show up in data centers and clouds. Current two categories of approaches, the test bed evaluation based and the software simulation based methods, both have certain shortcomings. While the test bed evaluation based...
ARINC 429 is a widely used bus standard in signal transmission of aeronautical electronic devices on civil aircraft. According to the analysis of ARINC 429 bus protocol and parameter characteristics, the thesis designs and implements synchronous and real-time simulation of multi-channel's 429 signals, coming from subsystems of a certain type of airplane. On the basis of simulation result, the author...
As sensor networks are finding widespread use across many applications, designers increasingly must not only focus on application development, but also on sensor network optimizations. Given the complexities of sensor networks and the difficulty of analyzing the long-term effects of design changes within a deployed system, simulation is often the only feasible option for evaluating such optimizations...
Simulation is an important method in the research and development of storage and network system. A good simulator can save memory and times. There are many simulators developed, but most of those simulator aimed at performance and data schedule algorithm. None of those simulators can model manipuility and dependability in large scale storage network. In this paper, we present the facilities and design...
RFID finds wide-ranging applications in many fields. When customers decide to implement a RFID application,they are possibly confused with some technical problems while allocating tags and readers to satisfy their business requirements. Due to the environment complexity, a general RFID deployment strategy is inapplicable that means the customers must create their own specific one. A simulator for...
