Cloud computing provide scalability and high availability for web applications using such techniques as distributed caching and clustering. As one database offloading strategy, elastic caching platforms (ECPs) are introduced to speed up the performance or handle application state management with fault tolerance. Several cache strtegies for ECPs have been proposed, say replicated strategy, partitioned...
This paper introduces a high-speed multi-channel data collection system based on AD7865 which can transmit data to PC by USB interface chip CY7C68013. Not only focusing on the character of the AD7568, this design but also complete the work of interface circuit and the programming of the whole system centered on the FPGA EP1C6Q240C8. By controlling the variation of the signal from analog to digital,...
Calculating RCS quickly and precisely has an important meaning to research the complex military target. Feko is an electromagnetic simulation software which can calculate and simulate the radar scattering character of complex military target especially to the electrically large 3-D multi-conducting bodies quickly and precisely. Based on the analysis to arithmetic of MOM, FDTD&PO, researching the...
For automotive AMT, the gear positions of gearbox are often different because of tolerances of manufacture and installation. And after a long-term use, the gear positions also change. So the original gear position parameters affect the shifting process. It is a cost-effective solution to add self-learning control into software and correct the gear position parameters adaptively. The paper proposes...
Adobe Acrobat 7.0 Professional Software can be used in engineering technology. We can conveniently measure the length between the straight lines (two points) and its correspondence increment of coordinate in the drawings by making use of this software function. In addition, we can choose different angle observations and the precise of distance observations (such as electronic tachometer), provide...
Taking the campus of Guilin University of Electronic Technology as prototype, combing with the software of 3Ds max and other virtual stimulate technology, a virtual campus has been developed. In this paper, a real-time roaming system of Virtual campus is fulfilled by using a VR-Platorm and data base connection. In addition, 3D-virtual campus implement some function including self-excursive trip, path...
To mobile communication requirement of portable device, a USB On-The-Go (OTG) communication system terminal, based on Freescale's 32-bit MCU - MCF52223, is designed in the paper. The system terminal can implement USB host function and USB peripheral function. The system design includes software part and hardware part. The hardware design includes power management circuit and interface circuit design...
Selective regression testing involves retesting of software systems with a subset of the test suites to verify that modifications have not adversely impacted existing functions. Although this problem has been heavily researched, it has never been discussed in the context of SaaS (Software as a service). This paper presents the specific requirements, challenges and benefits in delivering regression...
As the diversity of software status and the uncertainty of software operation, the traditional methods to construct software reliability operational profile are difficult to be applied to reliability testing. This paper introduces an approach to generate operational profile based on scenario. It partitions the usage of software into various paths of software running according to the users and missions...
SOE is the future enterprise operation model, the basis of which is that each business unit operates as a service-providing component. PESOP(Process Equipment Service-Oriented Platform ) is put forward as a prototype of SOE implement. The framework, function of PESOP are layed out in the paper. In addition, taking account of QoS(Quality of Service), an extending SOA model is propounded. At last, the...
Safety is crucial for software intensive systems. Safety-related accidents have resulted in great losses of human, system, environment and mission. However, safety concept is far long to be correctly understood and adequately engineered. Safety is more of a social problem than a technical problem, which addresses social risks instead of solely technical hazards. In engineering practices, most of safety-related...
In this paper, we use an FPGA platform and a high level synthesis tool, called Impulse C, to speedup a statistical Line Of Reaction (LOR) estimation for a high-resolution Positron Emission Tomography (PET) scanner. The estimation algorithm provides a significant improvement over conventional methods, but the execution time is too long to be practical for clinic applications. Impulse C allows us to...
According to the need of industrial and agricultural production and living, we introduce “scatter sequence” of a regular triangle and build an optimization design model to maximize the minimum scatter numbers. Based on LINGO software, we obtain the solution of the minimum scatter numbers and their coordinates in some “scatter sequences” of the regular triangles with different numbers of points and...
Discrete manufacturing (DM) refers to produce products in non-sequential processes so as to respond to market and customer requirements quickly under limited lead-time. However, in shop-floor management, DM companies usually confront challenges such as information gaps between different manufacturing units, slow responsiveness to customer changes, and poor visualization. The main reasons are lacking...
The reactive computational model is pervasively used as a proper abstraction of web-based applications which receive inputs and generate outputs throughout execution. The present static enforcements of information flow security on reactive program are either based on type system or abstract interpretation. In this work we first propose an approach using automated verification to check conformance...
Agile Development is a kind of iterated software development method. Its basic concept is people-centered. Estimate and scheme of Agile Methodologies are different from the traditional ones. Most papers at home and abroad about Agile Development mainly concentrate the contrast and fusion between Agile Development and traditional methods. However, researches about estimate of Agile Development procedure...
As cloud services proliferate, it becomes difficult to facilitate service composition and testing in clouds. In traditional service-oriented computing, service composition and testing are carried out independently. This paper proposes a new approach to manage services on the cloud so that it can facilitate service composition and testing. The paper uses service implementation selection to facilitate...
Private attributes of Online Social Network (OSN) users can be inferred from other information (which is usually from users' friends and group information). To address this, social networking sites allow users to hide their friend lists and group lists, so that general public cannot see them. However, if a user doesn't make his friend list public, but his friends have public friend list where we can...
