With the influx of multi-media streaming content over the Internet, building a streaming infrastructure that would support flexible Next Generation Internet application in a scalable way on heterogenous access technology is most desirable. This paper presents a streaming architecture which provides some innovative methods and technique that would help build an IP based radio/TV network. This wo...

The Smith-Waterman algorithm is widely used to determine the optimal sequence alignment between two DNA sequences. This paper presents an innovative method to significantly reduce the computation time and memory space requirements of the traceback phase of this alignment algorithm. It also presents a flexible and scalable hardware architecture for accelerating such method, which can be easily e...

Data warehouses are in use for more than a decade but companies are still finding it difficult to decide on the approach they should take for successful implementation. Data warehouse architecture plays a major role the successful construction of data warehouse. This paper proposes an approach of constructing local data marts at source and integrating them at enterprise level by creating physic...

This paper reports on the activities at IMEC that will lead to a 100Mb/s indoor communication system based on multi-carrier modulation. The goal is to build a wireless local area network, which can compete with today’s wired solutions in terms of cost and performance. It is shown how a dedicated ASIC architecture implements an OFDM modem with 256 carriers that allows transmission of complex sym...

As communication resources in VANETs are limited, they have to be used efficiently to achieve communication even under interference, especially in high load situations, where high packet loss is expected. Packet loss occurs on the channel or it occurs in the local queue due to a saturated channel. This article introduces a model that determines the network capacity and the influence of hidden s...

Enterprise architecture management (EAM) has long been propagated in research and practice as an approach for keeping local information systems projects in line with enterprise-wide, long-term objectives. EAM literature predominantly promotes strictly governed and centralized coordination mechanisms to achieve the promised alignment contributions. Notwithstanding the increasing maturity levels ...

The functionality and efficiency of micro mobility schemes in wireless networks has a great impact on the overall performance of the whole network. In small cell wireless LAN environments, the network must support both frequent and numerous handovers at the same time. Together with providing fast and reliable handoffs, the micro mobility scheme must not affect the service perceived by users. Th...

The World Health Organization’s (WHO’s) World Health Report 2010, “Health systems financing, the path to universal coverage,” promoted universal health coverage (UHC) as an aspirational objective for country health systems. Yet, in addition to the dimensions of services and coverage, distribution of coverage in the population, and financial risk protection highlighted by the report, the conside...

A variety of functionally important protein properties, such as secondary structure, transmembrane topology and solvent accessibility, can be encoded as a labeling of amino acids. Indeed, the prediction of such properties from the primary amino acid sequence is one of the core projects of computational biology. Accordingly, a panoply of approaches have been developed for predicting such propert...

In the last 5 years the authors worked as partners in a number of international projects in the field of e-learning, applying directly the Virtual campus paradigm. A thorough consideration of the specific training needs of the potential customers, their background and available infrastructure was seen as a precondition for success of the developed local context-oriented training solutions. The ...
