For omni-directional imaging based cooperative robot vision system, panorama unrolling is an important problem. We present an eight direction symmetry reuse algorithm for this problem, principles of this algorithm are: 1) Treat the original image to be unrolled as a series of co-centric circles, and uniformly partition them into eight parts of symmetrical sector regions. 2) According to symmetry principle...
This paper mainly discusses online tasks scheduling problem on hybrid CPU-FPGA reconfigurable systems. In these systems, hybrid tasks may be binary codes executed on CPU as well as hardware logic circuits implemented on FPGA. Tasks scheduling algorithms of conventional operating systems are not suitable for scheduling hybrid tasks on CPU-FPGA architecture. Based on a real reconfigurable system prototype,...
Healthcare organizations have met dynamic changes. They have contributed to intensify competitive activity between healthcare providers. These changes have forced the organizations to consider wide improvement of their activities and to adopt the use of new technologies in all the organizations' operations. Recently, there have been high demands for collaborative medical services between western and...
In this paper, we present management system of metropolis energy information (MSMEI) that manages the information of water meter, electricity meter and gas meter, the three basic elements of a city. In contrast to the traditional system as "single-user" program for collecting data, we have founded an architecture offering surprisingly strong support for cooperation among different workgroups...
The paper presents a distributed interactive vehicle simulation system for driving training based on the distributed interactive simulation (DIS) technology. It describes the system requirements, presents the system design particularly the vision subsystem design, and discusses the key techniques for the implementation of the proposed system including real-time communication, model partition, and...
This paper is concerned with the simulation and optimization research of light optical systems of car lighting projectors. In the paper, an attempt was made to use all accessible information about the relationships between elements in a vehicle reflector system which an engineer can choose and manipulate using computer aided design systems. Computer science achievements and neural networks were used...
A wireless remote control pruning machine was developed for plantation forest. The new designed system mainly consists of two parts: a transmitting system in the form of a hand controller and a receiving system mounted on the frame of the machine to drive the mechanical system. The idea of using the complex programmable logic device (CPLD) to realize the digital signal processing for the control system...
The geometry of CAD model needs to be idealized in order to reduce the complexity of the finite element model. A thin solid model should be abstracted to midsurface model. This paper describes a graph-based method that extracts midsurface patches from solid model and joins them automatically. Face-pairs are first found by ray-casting process, and midsurface patches are generated by geometric interpolation...
We designed and implemented MSFSS, a scalable and flexible distributed file system for storage and retrieval of mass small files. MSFSS is a platform built upon the existing commodity file systems. It automatically stores files onto the best-fit commodity file systems according their access patterns. To avoid central bottleneck, it optimizes metadata size, separates metadata operations from file data...
Health-care organizations are now moving toward integrated delivery systems to provide high-quality care, as they are being held to an ever-increasing scope of accountabilities. This paper introduces developing status of telemedicine. Telemedicine is based on the technology of telecommunication, and it is one of the application of computer supported cooperative work (CSCW). Computer supported teleconferencing...
There are many human-computer interactions in CAD software. Many commands have to be completed with many steps and the users have to remember lots of commands and parameters. It designs the system frame based on MVC pattern and command pattern for single step interaction software. After the users select entities or snap points, the commands matching the selection will be judged. The users' behaviors...
View maintenance is an important field in the research of dataware house. This paper provides an online view self-maintenance method based on source view's increment to keep the materialized view consistent with the data source. We use the cooperation between the integrator at warehouse and the monitor at data source to maintenance the view, and the method does not require to query back to data source,...
XML which is a new language for data representation is expected to become a universal format for data exchange on the Web. Generally speaking, we make some changes on XML documents as time goes by. Because temporal XML can store the successive versions of a document in an incremental fashion, it provides us a high effective method for version management. Of course, XML is more natural than RDB on...
To support a collaborative environment and strengthen information management for the entire product lifecycles management (PLM) of products, there are increasing demands on developing new-generation product representations. The representations need to be of software platform independence, rapid sharing of information between geographically distributed applications and users, support of the entire...
Customer relationship management -CRM -is a broad term that can cover every mode of customer interaction. This concept has been widely used in business language, enabling companies to gain more knowledge about their customers which, in its turn, can be used to improve marketing and sales targeting, improving their results. University and research institutions (URIs), as any other organizations, also...
With the internet technology developing and web information exploding, users urgently need a stronger web information retrieval function. For the better and stronger function, the sequence of search result queue and the correlation of query expression are the key problems that could be computed by similarity algorithm. Now we recommend a new method which is ontology-based weighted semantic tree similarity...
Since the structural conflicts in workflow processes can lead to malfunctioning of workflow management systems, the problem should be detected before workflow processes are put into execution. In this paper, we propose a combined graph-reduction and graph-search algorithm "CWRS" to verify workflow graphs. This algorithm reduces a cyclic workflow graph to an acyclic workflow graph, and then...
Self-management is an emerging computing paradigm to deal with the arising complexity in today's cooperative design environment. An essential element of self-management is a monitoring system. This paper proposed an agent-based generic monitoring system (AGeMoS) to integrate multiple probe solutions in order to support the monitoring of various systems in multiple aspects, including functionality,...
Heterogeneity and uncertainty are two main characteristics of pervasive computing environment and CSCW. CSCW can be viewed as a special case of pervasive computing. Middleware is a good approach to accommodate heterogeneous and dynamically changing devices for CSCW and pervasive computing. In this paper, we propose the service discovery method adopted in our DOM-based middleware architecture, which...
The rapidly changing market requires integrating information and collaborating among organizations to schedule jobs to machines that satisfy the objectives of service providers, and requesters. Moreover, delivering dynamic scheduling remains a major challenge especially when a diverse number of service providers and service requesters are geographically distributed. In this dynamic environment, scheduling...
