    Speech is the most natural and widespread form of human communication. That is why speech synthesis has interested researchers for decades. It turns out that developing an unlimited text-to-speech system is an enormous task. The traditional methods (synthesis by rule and synthesis by concatenation of pre-recorded sounds) used for this have not given good results. In such a situation, neural networ... View full abstract»

    Content-based image retrieval is one of the current active and promising research topics in image analysis and image management. The work of transferring the results of this research to support images in DBMS has also been initiated by many researchers and commercial systems. We first illustrate the importance of using content-based operations in combination with the traditional database operation... View full abstract»

    We propose a form-based approach for reverse engineering of legacy relational database applications. The approach consists of three dependent steps: (1) acquisition of both structure and instances of forms; (2) extraction of the static aspect of the legacy database: through a combination of forms structures and data instance analysis, forms relational sub-schemas and their constraints are derived....

    This paper maps a new application, namely vector-scalar operations, onto the M1 MorphoSys (from UCI) reconfigurable computing system. A performance analysis study of the M1 RC is also presented to evaluate the efficiency of the algorithm execution on the M1 system. For instance, two algorithms on an 8/spl times/8 RC array M1 were run, and numerical examples were simulated to validate our results, ... View full abstract»

    We propose a formalization of the COSMIC Full Function Point (COSMIC-FFP) measure for the Real-time Object Oriented Modeling (ROOM) language. COSMIC-FFP is a measure of the functional size of software. It has been proposed by the COSMIC group as an adaptation of the function point measure for real-time systems. The definition of COSMIC-FFP is general and can be applied to any specification languag... View full abstract»

    We propose a model for building object oriented applications based on the composition of application slices or fragments that provide their own overlapping definitions or expectations of the same domain objects. Different slices may implement different functional or implementation concerns, or embody different access rights and privileges to the same domain objects. We call such slices views and w...

    The production of interactive multimedia content is in most cases an expensive task in terms of time and cost. It must hence be the goal to optimize the production by exploiting the reusability of interactive multimedia elements. Reusability can be triggered by a combination of reusable multimedia components, together with the appropriate use of metadata to control the components as well as their ... View full abstract»

    Metrics are useful mechanisms for assuring database quality. However, it is necessary to prove the practical utility of the metrics because they must be used in real life. Consequently if the metrics are not useful from a practical point of view, they must be rejected. We present the metrics we have proposed for controlling the quality of relational databases and we present the case study develope... View full abstract»

    A multi-agent approach to problem resolution is located beyond the complexity of the system of agents and resides in the multitude of interactions between the system components. These multiple interactions, if they permit the resolution of a complex problem, also lead to conflicting situations and situations which are undertaken by agents carrying out redundant actions. Then, it becomes necessary ... View full abstract»

    E-commerce systems are specialized instances of distributed processing systems. The Common Object Request Broker Architecture (CORBA) provides a sophisticated infrastructure to develop and deploy distributed objects. As systems become more complex and geographically distributed, it is becoming increasingly difficult to conduct cost-effective, systematic and comprehensive testing on such systems. U...

    We present a distributed path selection procedure which has the objective of balancing the load in the network. It is used here in a connection oriented framework and is based on selecting, at each hop along a partially computed path, any one of the available routes to the destination. As far as we know, our approach is the first distributed multipath routing algorithm guaranteed to be loop-free a... View full abstract»

    A bi-criterion approach for the nominal airline crew rostering problem is developed. The nominal crew rostering problem considers the assignment of crew staff to a set of pairings covering all the scheduled flights so that operation costs are minimized while its solution must meet hard constraints resulting from the safety regulations of civil aviation as well as from airline internal agreements. ...

    For several decades, research on natural language processing (NLP) has been dominated by the symbolic approach. However, during the last few years, there has been increasing interest in the connectionist technical applicability for NLP to converge towards connectionist NLP (CNLP). In this paper, we propose a connectionist model for the generation of an internal representation of the sense of a sen... View full abstract»

    In this paper, neural networks have been proposed as an alternative technique to build software reliability growth models. A feedforward neural network was used to predict the number of faults initially resident in a program at the beginning of a test/debug process. To evaluate the predictive capability of the developed model, data sets from various projects were used. A comparison between regress... View full abstract»

    In the visual programming domain, the stress of research is laid on the use of visual formalism, which is considered to be more intuitive than the textual formalism, in the programming task. Some visual languages are based purely on data flow. With such languages, the execution order depends on the availability of data and it is therefore difficult to specify some programming constructs such as co... View full abstract»

    Quality of service guarantees for multimedia communication systems have been considered on several abstraction levels. In the multimedia networking field it is typical to identify the minimal QoS requirements of an application to save resources by guaranteeing its functionality. Many of these applications can operate in spite of an imperfect delivery of media data, while other applications such as... View full abstract»

    Parallelism has generated new concepts and approaches making it possible to conceive competitive systems and parallel architectural configurations. These two concepts are hard to bring altogether and require a precise definition of the structural elements of algorithm and their projection on suitable parallel architectures. The work described, tries to concretize this merge of concepts for a class... View full abstract»

    Software reuse has been claimed to be one of the most promising approaches to enhance programmer productivity and software quality. One of the problems to be addressed to achieve high software reuse is organizing databases of software experience, in which information on software products and processes is stored and organized to enhance reuse. We present a system to define and construct such databa... View full abstract»

    Considers the problem of image restoration degraded by a shift-invariant blur function and corrupted by white Gaussian noise. We propose a modified Hopfield neural network-based image restoration. Two algorithms with two updating modes using the modified Hopfield neural network are presented: (1) sequential updates, and (2) n-simultaneous updates. In the sequential algorithm, only one element of t... View full abstract»

    Simulation of turbulent fluctuations in ship wakes is one of the complex applications of large eddy simulations in computational fluid dynamics (CFD). Ship wake simulation requires extensive computations and large amounts of computer resources. The accuracy of ship wake prediction is limited by the memory of the workstation. We present the parallel implementation of large eddy simulations (LES) of... View full abstract»
