Cím:UML-based modeling of data-oriented web applications / Attila Adamkó
Dátum:2006
ISSN:0948-695x
Megjegyzések:Recently a growing demand has arisen for methods for the development of small- and medium scale Web Information Systems (WIS). Web applications are being built in a rapidly changing environment where requirements are usually unstable. Short-time design and implementation are needed in response to the new technologies. Our work focuses rather on the design and construction of Web applications, than management. Flexibility is a major requirement in such applications, and also in a database-backed environment for the structure and presentation of the sites. We propose a systematic design method for Web applications which takes into account the data-oriented aspects of the application. The method is based on a UML profile adapted to the problem domain by means of stereotypes as well as a strategy for generating code templates from such models. We provide a method to derive the navigation model from the structural model of a Web application. We will also show guidelines for the development of the Data Layer of data-oriented Web application. Moreover, why to divide the business logic layer into two parts: the pure application logic for managing the workflow of the application and the storage logic responsible for the data structures. Rapid development is enabled by providing roundtrip engineering capabilities with support for automatic code generation. We will show the role of XML: why to use XML to support both the reuse of content and context-dependent delivery. An advantage of the proposed methodology is that several steps can be performed is a semi-automatic way providing rapid development and prototyping.

Cím:The mobiDIÁK Educational Portal / Péter Antal, Norbert Bátfai, István Fazekas, Péter Jeszenszky
Dátum:2006
Megjegyzések:In this paper we present our aims in the mobiDIÁK (i.e. mobile STUDENT) portal that we have been developed and are running. Our essential goal was to create a portal engine, that is: (1) self-organizing, i.e. it has built in mechanisms by means of that it is able to exploit the power of the user community around the portal on behalf of its continuous growth; (2) for educational purposes; (3) mobile, i.e. its main services are also accessible from mobile devices.We have developed the portal engine ourselves that serves the basis to the portal. We are running the portal hourly at the Faculty of Informatics at the University of Debrecen, Hungary.We give an overview of the main portal services and also of the content offered by the running portal.

Cím:Applications of neighborhood sequence in image processing and database retrieval / András Hajdú, János Kormos, Tamás Tóth, Krisztián Veréb
Dátum:2006
ISSN:0948-695X 0948-6968
Megjegyzések:In this paper we show how the distance functions generated by neighborhood sequences provides exibility in image processing algorithms and image database retrieval. Accordingly, we present methods for indexing and segmenting color images, where we use digital distance functions generated by neighborhood sequences to measure distance between colors. Moreover, we explain the usability of neighborhood sequences within the eld of image database retrieval, to find similar images from a database for a given query image. Our approach considers special distance functions to measure the distance between feature vectors extracted from the images, which allows more exible queries for the users.

Cím:The "MEDIP - Platform independent software system for medical image processing" project / András Hajdu, János Kormos, Zsolt Lencse, Lajos Trón, Miklós Emri
Dátum:2006
Megjegyzések:In this paper we present the structure and the achieved results of the R&D project IKTA-4, 6/2001 "MEDIP - Platform independent software system for medical image processing" supported by the Hungarian Ministry of Education. The aim of the project was to develop a software background for our basic and applied research in the field of medical imaging that can be used in clinical routine, as well. Realization was based on the experience of information technology and medical imaging research university teams and a company specialized on software and hardware developing for nuclear medicine. The aims also reflect some former research and development activities of the participants. Thus some of them are well experienced in registration, segmentation and image fusion techniques. These experiences were also considered in the determination of the main purposes. The capabilities of the provided software library were demonstrated through test applications from the fields of orthopedics, oncology and nuclear medicine.
