This paper describes our experiences in teaching a first year object-oriented programming course. We used Java as a vehicle to teach programming principles and BlueJ as a Java development environment. The course was heavily supported by Web-based resources delivered through WebCT. So far we consider the overall students' learning experience as being considerably enriched and a positive one

An L(2, l)-coloring of a graph G is an assignment of labels from {0,1,..., A} to the vertices of G such that vertices at distance two get different labels and adjacent vertices get labels that are at least two apart. The X-number X(G) of G is the minimum value A such that G admits an L(2,1)-coloring. It is well known that the problem of determining the X-number is NP-hard. The Fibonacci cube network was recently proposed as an alternative to the hypercube network. Three different evolutionary algorithms are presented to find optimal or near optimal L(2,1)-coloring of the Fibonacci cubes. The algorithms are compared with the Petford-Welsh probabilistic algorithm

The aim of the paper is to present essential quantitative and statistics parameters determined in a dedicated microscope image processing application. The statistics offer the possibility to consider relevant measurements for assisted diagnosis. Representative quantitative parameters were used in a dedicated medical image processing application, Formdet, for DNAt AgNor, Stereology, Nucleus/Cytoplasm measurements. New facilities concerning the preprocessing, specific quantitative parameter measurements, archiving were considered for medical investigations

Documentation analysis and organisation are vital to the researcher when trying to understand the evolution of patrimonial edifices and sites. But the documentation that serves as source of evidences is far from being exhaustive or nonambiguous. Its very uncertainty is what really matters for researchers, and is therefore what we really need to represent inside 2D or 3D graphics. What solutions can one base on when trying to generate representations what would not say more about an edifice than what is really known? We present experiences in which, at various scales, we investigate the usability and graphical language of 2D/3D representations. We derive from these experiences remarks on how representations in the field of the architectural heritage can adhere to the notion of uncertainty and in the end really mean something for the researcher or practitioner. In conclusion to the paper we underline lessons we have learnt from these experiences on how to produce and exploit sustainable graphics in the field of the architectural heritage

Aligned with the appearance of e-Business the view on business had to change. Many new organizations with new business models, business cases, and new processes were established. An example of new processes is also "customer relationship management". We describe the importance of customers for an organization and stress the basics for customer relationship management implementation. Also main phases of successful CRM integration are presented. CRM key success factors and reasons for CRM implementation failure should also be considered

In the field of the architectural heritage, a comprehensive analysis of the historical documentation concerning sites or edifices is an unavoidable step in their understanding. Yet few solutions exist that would bridge the gap between VR techniques and solutions for documentation. In the history of architectural representation, we observe that representation has since the renaissance been understood as a mean to deliver information. Our proposal investigates possibilities opened today to reapply this vision to information visualisation and retrieval. In this paper we present solutions investigated in order to use the 3D representation of architecture as an interface to a heritage documentation. Elements discussed will be an analysis of the information we deal with, as well as the real-time, Web-based solutions developed in order to visualise objects with regards to domain specific issues such as shape uncertainty or hypothesis justification. This research is experimented on the city of Krakow (Poland) and its architectural evolutions

One of the crucial features of transition countries is the insufficiency of funds necessary to start and operate different nonprofit oriented projects. In order to realize their projects, nonprofit organizations in transition countries have to rely mostly on foreign sources, i.e. on donors from the developed countries. The Internet as one of the visually strongest means of global communication is an obvious and reasonable way to achieve transparency of nonprofit projects. A Web portal, which would present projects to potential donors in an interesting and visually attractive way, needs to be developed systematically. Given that the Web is a global information space, when creating project presentation systems, it is necessary to approach data modeling on the basis of the defined information requirements in the function of finding donors

It can be stated for a fact that relational databases are still the most efficient way of storing large amounts of data. Naturally, this fact caused necessity for developing systems that would allow high level customization of user interface still with efficient data acquiring. Architectures of such systems are becoming more and more modular. This paper describes a model of designing such multitier, multiuser system which deals with large amounts of data

E-government, as a segment of e-economy, has attained much interest in order to improve communications and level of services between governments and citizens. It is clear that successful e-government implementation requires not only introduction of modern information technology, but also business renovation, business process reengineering and e-business strategy. The main goal of the paper is to present the characteristics of business renovation efforts and readiness for e-government in Slovenia. The case of business renovation project in one of the Slovene Ministries, where the process modelling, analysis and simulation were extensively used is shown. The simulation modelling proved useful since it shows the process as a whole, drawbacks of the existing process, bottlenecks in the process execution, provides critical insight into process execution etc. The results of the business renovation show in reduced execution times, organizational changes, simplified business processes which represent a good foundation for informatization as a next step towards e-government
