Information and Communication Technologies as means for self-improvement at remote universities: the example of Urgench State University, Uzbekistan

This paper describes the research conducted at the Information Resource Center of Urgench State University, located in the Khorezm region of Uzbekistan, on the possibilities and challenges the students and lecturers face in their pursuit for self-improvement and self-education. The article discloses new qualitative approaches and IT methods in the teaching and educational processes in higher education of Central Asian countries in transition, the overall aim of which is to close the gap and shape the spiritual values of the young generation in the globalizing world. The framework conditions for this have been set by the Government of Uzbekistan through particular Decrees, aiming at the creation of e-education at universities and institutions throughout the country and specifically in the remote regions as to improve the access to regularly updated information, to motivate the use of IT in classes as well as to enhance the responsibility of the information services of universities for assuring the quality of research and teaching (pedagogical) activities of the lecturers. The research showed that the Internet can function inter alia as a controlling device when education is delivered through the web. Collection, analysis and preparation of educational-methodological materials on specific subjects and extracurricular activities require specific knowledge on IT and information literacy both in the teaching staff and the students

MonALISA : A Distributed Monitoring Service Architecture

The MonALISA (Monitoring Agents in A Large Integrated Services Architecture) system provides a distributed monitoring service. MonALISA is based on a scalable Dynamic Distributed Services Architecture which is designed to meet the needs of physics collaborations for monitoring global Grid systems, and is implemented using JINI/JAVA and WSDL/SOAP technologies. The scalability of the system derives from the use of multithreaded Station Servers to host a variety of loosely coupled self-describing dynamic services, the ability of each service to register itself and then to be discovered and used by any other services, or clients that require such information, and the ability of all services and clients subscribing to a set of events (state changes) in the system to be notified automatically. The framework integrates several existing monitoring tools and procedures to collect parameters describing computational nodes, applications and network performance. It has built-in SNMP support and network-performance monitoring algorithms that enable it to monitor end-to-end network performance as well as the performance and state of site facilities in a Grid. MonALISA is currently running around the clock on the US CMS test Grid as well as an increasing number of other sites. It is also being used to monitor the performance and optimize the interconnections among the reflectors in the VRVS system.Comment: Talk from the 2003 Computing in High Energy and Nuclear Physics (CHEP03), La Jolla, Ca, USA, March 2003, 8 pages, pdf.

Marketing management of a successful e-business

Marketing management occupies an increasingly important position in the business world, as well as in the sphere of electronic commerce. Some participants, however, underestimate the importance of this marketing support, which may be one of the major causes of the failure and inability of some companies operating on the Internet to grow. The aim of this paper is to develop an effective marketing management process model, which can significantly contribute to the increased competitiveness of companies operating on the Internet. The validity of this model is then applied on a Czech e-shop, which has long been one of the leaders of the Czech Internet market. To achieve the objective of this paper the current situation will be analysed, and synthesis of the findings from research literature as well as modelling using the methods of abstraction and specification will be performed. This article is focused on Czech Internet market. Results of the survey (case study) will be used for further research in the field of e-business

Global-Scale Resource Survey and Performance Monitoring of Public OGC Web Map Services

One of the most widely-implemented service standards provided by the Open Geospatial Consortium (OGC) to the user community is the Web Map Service (WMS). WMS is widely employed globally, but there is limited knowledge of the global distribution, adoption status or the service quality of these online WMS resources. To fill this void, we investigated global WMSs resources and performed distributed performance monitoring of these services. This paper explicates a distributed monitoring framework that was used to monitor 46,296 WMSs continuously for over one year and a crawling method to discover these WMSs. We analyzed server locations, provider types, themes, the spatiotemporal coverage of map layers and the service versions for 41,703 valid WMSs. Furthermore, we appraised the stability and performance of basic operations for 1210 selected WMSs (i.e., GetCapabilities and GetMap). We discuss the major reasons for request errors and performance issues, as well as the relationship between service response times and the spatiotemporal distribution of client monitoring sites. This paper will help service providers, end users and developers of standards to grasp the status of global WMS resources, as well as to understand the adoption status of OGC standards. The conclusions drawn in this paper can benefit geospatial resource discovery, service performance evaluation and guide service performance improvements.Comment: 24 pages; 15 figure

Planning for execution monitoring on a planetary rover

A planetary rover will be traversing largely unknown and often unknowable terrain. In addition to geometric obstacles such as cliffs, rocks, and holes, it may also have to deal with non-geometric hazards such as soft soil and surface breakthroughs which often cannot be detected until rover is in imminent danger. Therefore, the rover must monitor its progress throughout a traverse, making sure to stay on course and to detect and act on any previously unseen hazards. Its onboard planning system must decide what sensors to monitor, what landmarks to take position readings from, and what actions to take if something should go wrong. The planning systems being developed for the Pathfinder Planetary Rover to perform these execution monitoring tasks are discussed. This system includes a network of planners to perform path planning, expectation generation, path analysis, sensor and reaction selection, and resource allocation

Supply chain control: Trade-offs and system requirements

The official published version can be accessed from the link below.A paper describes the underlying forces which drive change in manufacturing enterprises and supply chains. It sets out the complexities in modern capitalism and global economics and illustrates the trade-offs that can be made. IT systems which are required to assist improvements to both customer service and enterprise manufacturing performance are explained, alluding to the special case for the semiconductor industry. Arguments are presented showing how the new tools being developed with the ESPRIT project 20544, X-CITTIC, will satisfy the control needs for a virtual enterprise.
