In recent years, the vital development of the Internet offers increasing opportunity for electronic commerce. E-commerce attracts much attention from enterprises, not only to get connection with others and make a profit from their product/service, but also to reduce the costs of internal and external operational procedures. Procurement is a very critical task because it is a matter not only of making a profit. but also of staying in business in a highly competitive environment. In the government sector, procurement is sometimes the source of corruption, scandal and abuse of public resources. Besides inadequately qualified personnel, "transparency" of the procurement environment becomes another source of problems in procurement procedure. This paper investigates a case study of e-commerce in the Taiwanese military organization by diagnosing and preventing procurement faults, constructing a transparent procurement environment. and enhancing military procurement efficiency, and is an attempt to establish an e-market environment via web-based architecture on e-procurement procedure. The design of a relational database is introduced and system implementation is presented. Also. efficiency and benefits of the proposed system are discussed. (C) 2002 Elsevier Science Ltd.

Clinical treatment delivery often involves multiple medical professionals, where collaborative teamwork is crucial to ensure the quality of diagnosis and therapeutic decision making. With the development of Internet of Medical Things (IoMT) and its applications in mobile health (mHealth), healthcare services can be delivered to remote users. However, a challenging situation arises when the data are volumetric and dynamic, it will be difficult to achieve real-time performance in information streaming and data dynamic rendering and synchronization over Internet, as is the case with cardiac procedures, where both the anatomy and dynamic function characteristics of the organ must be considered. To address this issue, we have developed new algorithms and a web-based collaborative software architecture to display dynamic volumetric data in a web browser to enable dynamic data sharing with remote healthcare professionals. We illustrate our system using the diagnosis and treatment planning of an atrial septal defect (ASD) repair as an example to evaluate the capabilities of our platform. In this example, a series of three-dimensional (3D) ultrasound images are registered and fused with the high-quality magnetic resonance (MR) cardiac data to provide complementary information;virtual septal occluder patches are modeled and integrated into the beating heart views to facilitate the planning of the procedure to occlude the ASD, and feedback is streamed amongst all participating professionals. Our algorithm runs on a *** server with webSocket protocol to synchronize dynamic heart rendering, so all the connected users can observe the same four-dimensional (4D) display of the dual-modality heart data during the process of examining cardiac anatomy, performing functional analysis, and sharing treatment strategies across distributed geographic locations. The presented computational models and software architecture create a new vehicle for collaborative exploration and manipulati

Online laboratories are offering new experimental potential for research and education purposes. This paper investigates the design and implementation of a web-based hybrid laboratory framework for research and education. based on the previous work of the Networked Control System Laboratory (NCSLab), a hybrid laboratory with a highly modular design providing plug-in free online experiments is discussed. The proposed modular design of the NCSLab is provided in four aspects as hardware, software, control algorithms, and deployment, which covers all of the phases that compose an online experimental platform. The experiments that are integrated into the NCSLab for research and education are also explored in detail. To verify the effectiveness of the proposed modular design, a virtual wiring fan speed control system and a physical wireless power transfer system are deployed as examples to illustrate the virtual and remote experiments, respectively. The modular hybrid laboratory has been applied to research and engineering education at Wuhan University, and the corresponding pedagogical evaluation verified the effectiveness of the NCSLab.

Accurate, complete, and timely health data sources are essential for progress in health care. Registry and research systems are foundations for conducting clinical and epidemiological research. Developing countries lack these systems due to the scarcity of the resources allocated for health information systems. In this study, we provide an integrated model for Turkey in order to optimize the utilization of resources. The Breast Diseases Registry system (BDRS) is implemented as an integrated disease-specific system for breast diseases in order to obtain a comprehensive use of patient health data for research and Breast Cancer Registry as well as an ancillary clinical tool.

The burgeoning capabilities of web browsers to exploit full-featured devices can turn the huge pool of social connected users into a powerful network of processing assets. HTML5 and JavaScript stacks support the deployment of social client-side processing infrastructure, while webGL and webCL fill the gap to gain full GPU and multi-CPU performance. Mobile Grid and Mobile Cloud Computing solutions leverage smart devices to relieve the processing tasks to be performed by the service infrastructure. Motivated to gain cost-efficiency, a social network service provider can outsource the video analysis to elements of a mobile grid as an infrastructure to complement an elastic cloud service. As long as users access to videos, batch image analysis tasks are dispatched from the server, executed in the background of the client-side hardware, and finally, results are consolidated by the server. This paper presents SaW (Social at Work) to provide a pure web-based solution as a mobile grid to complement a cloud media service for image analysis on videos.

A common vision of Augmented Reality (AR) is that of a person immersed in a diverse collection of virtual information, superimposed on their view of the world around them. If such a vision is to become reality, an ecosystem for AR must be created that satisfies at least these properties: multiple sources (or channels of interactive information) must be able to be simultaneously displayed and interacted with, channels must be isolated from each other (for security and stability), channel authors must have the flexibility to design the content and interactivity of their channel, and the application must fluidly integrate with the ever-growing cloud of systems and services that define our digital lives. In this paper, we present the design and implementation of the Argon AR web Browser and describe our vision of an AR application environment that leverages the WWW ecosystem. We also describe KARML, our extension to KML (the spatial markup language for Google Earth and Maps), that supports the functionality required for mobile AR. We combine KARML with the full range of standard web technologies to create a standards-based web browser for mobile AR. KARML lets users develop 2D and 3D content using existing web technologies and facilitates easy deployment from standard web servers. We highlight a number of projects that have used Argon and point out the ways in which our web-based architecture has made previously impractical AR concepts possible.

Instructional systems designers can face a difficult task with training development including curriculum content, delivery method. and learner assessment. This situation becomes more complex when multiple types of learners must be trained with overlapping but not completely similar content. This paper discusses a flexible web-based architecture that supports the tailoring of training content and learner assessment. The architecture supports the creation of multiple training treatments and assessments, and learner performance data collection.

How to facilitate efficient video manipulation and access in a web-based environment is becoming a popular trend for video applications. In this paper, we present a web-oriented video management and application processing system, based on our previous work on multimedia database and content-based retrieval. In particular, we extend the VideoMAP architecture with specific web-oriented mechanisms, which include: (1) Concurrency control facilities for the editing of video data among different types of users, such as Video Administrator, Video Producer, Video Editor, and Video Query Client;different users are assigned various priority levels for different operations on the database. (2) Versatile video retrieval mechanism which employes a hybrid approach by integrating a query-based (database) mechanism with content-based retrieval (CBR) functions;its specific language (CAROL/ST with CBR) supports spatiotemporal semantics of video objects, and also offers an improved mechanism to describe visual content of videos by content-based analysis method. (3) Query profiling database which records the "histories" of various clients' query activities;such profiles can be used to provide the default query template when a similar query is encountered by the same kind of users. An experimental prototype system is being developed based on the existing VideoMAP prototype system, using Java and VC++ on the PC platform.

In this paper, we present a web-based decision support system (DSS)-wSADfLOR-to facilitate the access of stakeholders to tools that may contribute to enhancing forest management planning. The emphasis is on a web-based architecture and a web graphic user interface (wGUI) that may effectively support the analysis of trade-offs between ecosystem services in order to address participatory and sustainable forest management objectives. For that purpose, the wGUI provides remote access to a management information system, enabling users to analyze environmental and biometric data and topological information as well. Moreover, the wGUI provides remote access to forest simulators so that users may define and simulate prescriptions such as chronological sequences of management options and the corresponding forest ecosystem services outcomes. Remote access to management planning methods is further provided so that users may input their objectives and constraints. The wGUI delivers information about tradeoffs between ecosystem services in the form of decision maps so that users in different locations may negotiate bundles of ecosystem services as well as the plan needed to provide them. The multiple criteria programming routines provide proposals for management plans that may be assessed further, using geographical and alphanumeric information provided by the wGUI. Results for an application to a forested landscape extending to 14,388 ha are presented and discussed. This landscape provides several ecosystem services and the development of its management plan involves multiple stakeholders. Results show that the web-based architecture and the wGUI provide effective access for stakeholders to information about the forest management planning area and to decision support tools that may contribute to addressing complex multi-objective and multiple-decision-maker management planning contexts. They also highlight that the involvement and participation of stakeholders in the design of
