Indexing can be viewed is the process of segmenting a large information with the indices acting as descriptors for the subspaces. In the case of information retrieval systems, the indices are used to retrieve documents based on a user query, whereas in the case of knowledge navigation systems, the indices circumscribe browsable spaces of documents. In this paper, I take the position that tradit...

DNA abundance provides important information about cell physiology and proliferation activity. In a typical in vitro cellular assay, the distribution of the DNA content within a sample is comprised of cell debris, G0/G1-, S-, and G2/M-phase cells. In some circumstances, there may be a collection of cells that contain more than two copies of DNA. The primary focus of DNA content analysis is to d...

Mobile communication devices may be used for spreading multimedia data without support of an infrastructure. Such a scheme, where the data is carried by people walking around and relayed from device to device by means of short range radio, could potentially form a public content distribution system that spans vast urban areas. The transport mechanism is the flow of people and it can be studied ...

The need for creating content repository stores for e-learning systems grows as the number of available materials increases. Moreover, along with the number of courses, the problem of describing them in a unified form appears. While there are standards used for strict classification of elearning content, the store model still seems to be based on preservative relational databases approach. In t...

Concept learning in content-based image retrieval (CBIR) systems is a challenging task. This paper presents an active concept learning approach based on mixture model to deal with the two basic aspects of a database system: changing (image insertion or removal) nature of a database and user queries. To achieve concept learning, we develop a novel model selection method based on Bayesian analysi...

Automated recognition of Activities of Daily Living allows to identify possible health problems and apply corrective strategies in Ambient Assisted Living (AAL). Activities of Daily Living analysis can provide very useful information for elder care and long-term care services. This paper presents an automated RGB-D video analysis system that recognises human ADLs activities, related to classica...

This paper considers the use of logic-based languages for multiagent negotiation. We begin by motivating the use of such languages, and introducing a formal model of logic-based negotiation. Using this model, we define two important computational problems: the success problem (given a particular negotiation history, has agreement been reached?) and the guaranteed success problem (does a particu...

Networks grow in scale and become more complex and heterogeneous as well. A lot of research effort is focused on the topic of network management. This is because nowadays a network management system is a vital component of any network installation. In this paper, we propose an extended network management information model that includes the time dimension. This view leads us to adopt a temporal ...

We combine statistical-mechanical approach for probabilistic image processing with DNA based biomolecular operations to construct associative memory for pattern recall. The statistical properties of the patterns are learned from the exposed examples, stored in memory and are recalled when presented with partial queries. The results show that our proposed memory model retrieves patterns with hig...

E-government is a field where oriented practice is considered crucial for its prosperity. Therefore, best practices are considered among the success factors of e-government portals. To this end, e-government maturity models can be used to provide guidance and guidelines to identify those best practices. After an extensive literature review, we have collected both; the e-government portals’ best...
