    In order to survive in highly competitive business environments, companies have to continuously change their business processes. It is apparent that developing dynamic models of business processes prior to their change could increase the success of reengineering projects. This research investigates a suitability of business process modelling tool ARIS for dynamic modelling of business processes. I... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (818 KB) | HTML iconHTML

    Skeletal injury operations are in general of high complexity and require extreme accuracy. That is why it seems practical that prior to a surgical intervention a geometric and mechanic model is prepared, which can be used to simulate various operational solutions. We present here a computerized system, which we call MedEdit, that helps the surgeon to plan the operation and with the use of a finite... View full abstract»

  • Gradient based selective weighting of neighboring pixels for predictive lossless image coding

    Publication Year: 2003, Page(s):483 - 488
    Cited by:  Papers (4)  |  Patents (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (566 KB) | HTML iconHTML

    Natural, continuous tone images have the very important property of high correlation of adjacent pixels. This property is cleverly exploited in lossless image compression where, prior to the statistical modeling and entropy coding step, predictive coding is used as a decorrelation tool. The use of prediction for the current pixel also reduces the cost of the applied statistical model for entropy c... View full abstract»

    Data warehouse systems have become a basic technological infrastructure in management decision making. Nevertheless, the overall utility of data warehouses remains unmeasured in most practical cases. As a consequence of this, IT-managers do not possess appropriate means to evaluate warehouse benefits in order to decide about investments in warehousing technology. We develop a controlling instrumen... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (592 KB) | HTML iconHTML

    Knowledge termination is the last, but mostly unperformed task in the knowledge life cycle. It is the process that describes the process of selecting and deleting unusable knowledge items. Through performing knowledge termination, organisations can avoid losing efficiency in the knowledge management practice by waiting for the search results, selecting the real useful knowledge items, or using wor...

    Preliminary research on the vocabulary size of Croatian lexical corpora shows that the distribution of types is regular and that deviations of the calculated values are within theoretically acceptable limits. The research also brought us to conclusion that Zipf's law in Croatian language is not applicable because the lexical density is different, i.e. the proportion of types and tokens in differen...

    Heterogeneity of computer environment allows execution of large diverse applications, but it also simultaneously aggravates mapping. We present a combined multicriterial mapping based on the MEVSP model. Model parameters originate from the level of application, platform, mapping and user. The most suitable prediction methods are long-term performance prediction, short-term prediction of threshold ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (579 KB) | HTML iconHTML

    In the theory and practice of information system design, implementation and functioning very little attention is paid to the systematic analysis of causes of information system failures and information systems goal setting. A vaguely defined goal of the IS implementation will result in solutions that will satisfy the demands of information system users, information system professionals and busines...

    Physical reality is the source of biggest abstractions, which are the base of scientific knowledge and of all the other forms in which reality is perceived. All human creations are the consequence of some interpretative and explaining systems, in the middle of which we can always find the concept of model. A model is "a key to a given problem". We give an answer to the question: "What should we un... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (483 KB) | HTML iconHTML

    We summarize our efforts in implementing a working multilevel secure database prototype. We have chosen belief-consistent multilevel secure relational data model (BCMLS) as a basis for our prototype because of its comprehensive semantics for interpreting all stored information. While semantically superior to other models, this model has not been implemented as a working system before. Our prototyp... View full abstract»
