Much attention is being directed towards IT to facilitate better management of information and enhance decision-making as a result of factors like: expenditure on information technology (IT); the imposition of legislation and implications of standards calling for timely, accurate and comprehensive reporting; and the need to respond to the increasing pace of change in organisations. Consequently...

Nowadays, inquiry learning, in which learners construct knowledge based on information they collect from real life experiments or simulations, plays an increasing role in education. Inquiry learning holds the promise of learners constructing deeper rooted knowledge as well as acquiring an inquiry competency, being better prepared for dealing with new and unknown situations and collecting and us...

Researchers have used advances in hardware technology to design larger and more complex real-time applications. Larger applications require new integration techniques while more complex applications require a restructuring of the underlying system support. We examine the system design issues of supporting SPAR-TAs (Soft PArallel Real-Time Applications). There exists a gap between hard real-time...

This paper proposes a new knowledge-based method for clustering metagenome short reads. The method incorporates biological knowledge in the clustering process, by means of a list of proteins associated to each read. These proteins are chosen from a reference proteome database according to their similarity with the given read, as evaluated by BLAST. We introduce a scoring function for weighting ...

When a computer is an integral part of a larger system, where it intensively interacts with the surrounding environment and frequently deals with real-time constraints, it is considered an embedded system. This communication describes the embedded system world: architecture, classification, characteristics, system limitations, and trends. It also discusses architectural features that cannot exi...

The current CMU Mach 3.0 microkernel exports simple timestamp and delay abstractions through host get time() and a timeout parameter to mach msg(). While this is sufficient for many purposes, it does not provide the precision or generality required for a variety of realtime applications. In this paper we describe extensions to CMU’s Mach 3.0 which provide users with flexible time-based synchron...

Entries in biomolecular databases are often annotated with concepts from different ontologies and thereby establish links between pairs of concepts. Such links may reveal meaningful relationships between linked concepts, however they could as well relate concepts by chance. In this work we present InterOnto, a methodology that allows us to rank concept pairs to identify the most meaningful asso...

atabases have become an integral part of many computer systems—ranging from complex systems that control air traffic, plant operations, and stock market transactions to general-purpose computing systems that run audio and video applications. Increasingly, computer systems—even general-purpose systems—are requiring real-time support, so it’s not surprising to hear more about real-time databases....

For a Tychonoff space $X$, we denote by $C_p(X)$ the space of all real-valued continuous functions on $X$ with the topology of pointwise convergence.  We study a functional characterization of the covering property of Hurewicz.

this paper evaluates the real exchange rate fluctuations and uncertainties resulting from it, in the iranian economy. for this purpose, at first indirect effect of real exchange rate uncertainties on economic growth through foreign investment, private investment and exports are expressed, then the real exchange rate uncertainties and its relationship with economic growth and final pattern of in...
