The formation of charge transfer excitons and the creation of lattice distortions are studied in short polymer chains by solving the self consistent equations of motion for the reduced single electron density matrix and the lattice displacement. The coupling of electronic motions to lattice dynamics gives rise to the formation of excitonic polarons, which can be identified in the femtosecond pump-probe signal.

They have been developed as fast as information data bases and electronic communication facilities were extended. Recently, portals with geographically referenced information became important and popular for different fields like geo information systems of cities (see e. or the presentation of economically relevant data in the context of regional marketing, foreign direct investment or tourism by indicating important objects like public institutions, companies, hotels, sights, etc. on maps. In this manner they may contribute to the improvement of industrial structure and the marketing of a region. For representing geographical data on maps, applications with special client-server-architecture have to be developed. There are different solutions for the Internet using HTML and JavaScript, Flash or Java Applets. In our contribution we discuss currently available solutions and show an alternative approach. Our solution is based on the Java Applet technology and Asynchronous JavaScript and XML (Ajax). This technology is part of the web solutions known as Web 2.0 which is strongly discussed and developed in the present. Our results are demonstrated as a user-friendly web application with data of the Slovakian region Špis (Zips). An extended version of this web solution could be nicely incorporated into a modern concept for tourism of the Špis region.

A1 - Hartmann, Michael A1 - Schleusener, Heinz A1 - Timčák, Geza T1 - Web 2-presentation of regional data T2 - 5th International Conference on Perspectives of rural tourism in the New Europe, Košice N2 - Web portals and many Internet solutions contain objects with a geographical reference such as the position of a company or a tourist attraction. Existing maps are protected by copyright. The licence fee is high and it is very expensive and complicated to create own maps. Freely useable and suitable maps for presentations, such as open source, do not exist – although the project OpenGeoDB is growing day after day. Recently, however some changes occurred. After a registration, Yahoo and Google offer interfaces to their map data for non-commercial users. This can be used for free. The interfaces offer advanced user possibilities for accessing maps, which are mostly high resolution ones, using the Web 2 methods. We show how to integrate Google´s API interface into one's own web applications and finally, how regional data, stored in a database, can be presented by this solution. Currently, Google does not have sufficiently detailed maps for Eastern Europe yet. Nevertheless, our web solution uses data of the region Zips (Špis) in Slovakia. It demonstrates how geo-based data can be used for supporting regional marketing concepts by Web 2 in the future.

ER - TY - CHAP A1 - Gocek, Pawel A1 - Hartmann, Michael A1 - Schleusener, Heinz T1 - Modern Technologies in client-server Architecture for Geo-Based Webportals: represented by examples for Companies in Food Technology and Food Industry T2 - Proceedings of the 7th International Conference on Food Science, Szeged N2 - In the last decade, portals on the WWW have been extensively developed for different applications in e-business, e-commerce, e-government or science and are used as an information and communication base. Recently, due to the progression of web- technologies, new user-friendly features could be added into portals. Among them the incorporation of geographic informations became most important since many relevant data are related to space. In such a way the value and the appropriate visualization of the relevant information as well as the ability to investigate the interrelation between different data could be reached (Bernhardt, 02). Geo-based web portals combine the features of common portals like searching for keywords or navigating with geo information systems (GIS). For a certain target group they provide a unique presentation of all relevant information within a region or a market, and provide user specific communication tools. In this context, providing maps is one of the main characteristics of geo-based web portals. Creating a geo-referenced map is a challenging and complex task since all relevant geo data like streets, objects, information of the landscape etc. have to be known and incorporated into the GIS. Therefore, a geo-object in the geo-based web portal has to contain both the geo-data and the content related data. Geo-data describe the structure of an object in space whereas the content related data provide additional attributes associated with the properties of the object (Dickmann & Zehner 2001). From the point of the architecture, a web-based map application consists of two essential components - the server and the client part. Typically, the server component is responsible for providing geographical information according to the client's request and returns the data and images suitable for the visualization back to the client application. The client component provides the user with a graphical user interface (GUI). Its main tasks are collecting the user input data and communicating with the server in order to retrieve the information as well as to provide interactive mechanisms for representing analyzing the results. The communication between the client and the sever component via a HTTP port is based on a defined request-response protocol. Typical solutions are implemented using JavaScript, Java applets or Flash and are discussed in more detail in the next section. In this contribution we describe an alternative approach using the Java Applet Technology, Asynchronous JavaScript and XML (Ajax). It's application for offering informations of companies operating in the field of food technology and food industry is shown. In such a way it represents a realization of our recently developed concept of a geo-based web portal (Hartmann et al, 05).
