Software diagnosis on MPSoCs, the process of finding functional bugs or performance inefficiencies in complex hardware-software systems, is challenging. As both software and hardware complexity grow, the software observability decreases. At the same time, understanding the intended software behavior has become more difficult. We present an integrated approach which combines domain-specific representations...
A portable human body joint power test system was developed using inertial sensor technology and wireless Bluetooth acquisition technology. A detailed description of the internal structure of the system and the data-processing method involved is provided. The test system uses the cubic spline interpolation method, which is very convenient for obtaining the maximum peak points of muscle isotonic contraction...
Gas transmission station is an important part of transmission system. How to effectively reduce the pressure loss inside the station and improve the transmission efficiency has become one of hotspots that pipeline operating companies pay much attention to. Sequential modular approach is proposed to realize the connection between devices and achieve a whole gas transmission station process simulation...
Space-time algorithm based on cyclic correlation matrix is introduced and the cyclostationarity of signals is taken into account. Numerical simulation shows that it can considerably improve the performance of the software defined antenna and therefore be widely used in variant fields.
The paper puts forward an abstract platform independent meta-model aiming for services and platform specified meta-model based on SCA (Service Component Architect). Next analyzes elements for transformation from platform independent meta-model to platform specified meta-model. And then puts out method for transformation. Finally, carries out the method.
Based on China's 2007 foreign exchange market daily foreign exchange offer as a sample study, this article is empirical testing of China's foreign exchange market effectiveness, through the run testing and examination-related sequences from the two methods of analysis. The results of run test is that China's foreign exchange market has not reached the validity of the weak, that is, the statistics...
Model-Driven Architecture (MDA) is a new software development method proposed by the OMG, which can automatically generate final complete application from the abstract model established against the business logic. It is based on UML and other industry-standard framework to support the software design and model visualization, storage and exchange, the core technology is the conversion between platform-independent...
Because of increasing configuration file, programmer need deal with the more work than ever. This paper put forward an idea that we can apply Class diagram of UML to the process of automatic building SCA configuration files framework, and complete a plugin through which this work can be carried out. Compared with the one written by manual work, the configuration produced by the plugin has many advantages,...
The demand for quickly delivering robust enterprise applications has increasingly become a business imperative today. Semantic web technologies have received much interest due to their prospect in facilitating seamless legacy system integration in support of new functionality development. In this article, we present a team collaboration oriented development framework (SSC-I) for designing and developing...
This paper designed a synthesized rural E-government system for use at the municipal to village levels. All the everyday information management functions are included in the system, such as social and public affairs, resources, financial transactions and so on. Because of the integration of office automation and geographical information system, the system can query the information in detail and provide...
To improve the efficiency and the security of tripping operation and lessen the labor intensity during the drilling operation, the concept of using computer to assist tripping operation was put forward in this paper. It is also very useful to enhance the automation level of the mechanical drilling rig. In this paper, after studying the oil rig equipped with hydraulic disc brake and pneumatic disc...
Architecture design and software implementation both contribute to the correctness of ultimate software products. So performance testing is very helpful to test the inconsistence between design and implementation since it is the mix reflection of both sides. Especially in embedded system, with limited resources, execution time is more likely to expose hidden defects. This research presents a time...
