The study of complex systems, either physical or cyber, could be carried out by experimenting with real systems, software simulators or emulators. This paper presents an innovative framework for an experimentation environment that incorporates both physical and cyber systems. The proposed approach uses soft real-time simulation for physical processes (based on Simulink) and an emulation test bed (based...
The emergence of new environments such as Cloud computing highlighted new challenges in traditional fields like performance estimation. Most of the current cloud environments follow the Software, Platform, Infrastructure service model in order to map discrete roles / providers according to the offering in each “layer”. However, the limited amount of information passed from one layer to the other has...
Distributed architecture is a fundamental way for science and engineering data application by aggregate power of computing resources connected by networks of the grid. This paper describes a innovative scenarios for intensive rainfall data analysis. The Flood Early Warning System is performed to give an alert in advance about the occurrence of heavy rainfalls around the world. The aim of the project...
In order to adapt to the trend of visualization of satellite mission, building a real time visual simulation platform is needed. Based on Satellite Tool Kit (STK) and MATLAB / SIMULINK, the Displayer Terminal written by VC++ through the use of STK / Connect interface technology and STK / X embedded technology was build, as well as the real time satellite mission analysis simulation model which was...
Mathematics model is usually used in Hardware-In-Loop simulation testing in engineering. In order to improve the limitation of this technology, we utilize the working environment simulation modeling, the real-time test script technology and the data-playback technology to propose a portable data-playback based Hardware-In-Loop simulation testing platform technology for reactive system. It could contain...
Smart meter network is one of the backbone for modern power grid or smart grid. It is very critical to have the right technologies for the efficient operation of smart meter network. Smart meter network requibres the right bidirectional communications medium and interoperability capability. As thousands of meters will be interconnected to the distribution power network, it is vital to combine communications...
A design scheme of remote model predictive control system is presented in this paper. Combined with the asynchronous messaging framework Errai, a network application system for remote model predictive control, which is based on GWT architecture, is developed and implemented by using RIA technique. The application field of MPC product is extended and the application function is expanded effectively...
Hard real-time applications in safety-critical domains — namely avionics, automotive, and machinery — require high-performance and timing analysability. We present research results of the parallelisation and WCET analysis of an industrial hard real-time application, i.e. the control code of a large drilling machine from BAUER Maschinen GmbH. We reached a quad-core speedup of 2.62 for the maximum observed...
The path analysis and trajectory planning of composite elbow winding machine is presented with the post-process technology. With the PMAC as the motion controller and the Windows operating system as the development platform, the real-time download of large capacity numerical control program is realized with the dual-port RAM communication. The real-time dynamic control process of elbow winding is...
This pager introduce the development process and result of wireless camera based on ARM11. The software is running on the development board S6410 made by HHtech. Some modules like Megapixels camera, Muti Format Codec and WIFI are in use. The Ubuntu installed in VMware is used as a cross-compile and debug platform. The final goal is to collect real-time images, to send them through wireless network...

Games provide an ideal test bed for computational intelligence and significant progress has been made in recent years, most notably in games such as Go, where the level of play is now competitive with expert human play on smaller boards. Recently, a significantly more complex class of games has received increasing attention: real-time video games. These games pose many new challenges, including strict...
This paper describes a middleware layer for soft real-time communication in wireless networks devised and realized using standard WLAN hardware and software. The proposed middleware relies on a simple network architecture comprising a number of stations that generate real-time traffic and a particular station, called Scheduler, that coordinates the transmission of the real-time packets using a polling...
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...
In view of the narrowband carrier communication widely used in the automatic meter reading system in low voltage power line of our country at present, this paper proposed the automatic meter reading system's design scheme based on the power line broadband carrier, overcame the narrowband carrier communication bandwidth to be excessively narrow, the speed to be excessively low, real time badly and...
Software Engineering is an important course for software related majors; yet it's also the most hated and most "boring" course among the students; teachers have difficulties in arousing the interest of their students, and there's hardly any doable practices that can be performed within the time/environmental limitation of the class. To address this issue, proposes a performance-oriented...
Due to the critical role of communication in project teams, capturing and analyzing developer design notes and conversations for use as performance predictors is becoming increasing important as software development processes become more asynchronous. Current prediction methods require human Subject Matter Experts (SME) to laboriously examine and rank user content along various categories such as...
