    Being able to accurately model the deformation of biological objects is vital to the success of many multidisciplinary studies such as computer-aided surgery simulation and planning, image-based medical diagnosis, and motion-based human identification etc. Among various modeling techniques, physical model becomes increasingly popular because the physical and mathematical rigors upon which the mode...

  • Reconciling Logic and Objects

    Logic and objects can be combined and reconciled in at least three main ways. The simplest and most conservative way is to use logic to describe OO systems. This is useful for specifying and proving properties of OO systems. A more ambitious, but also straight-forward way is to use logic to implement OO methods. Used in this way, logic can implement both condition-action rules and goal-reduction r... View full abstract»

    Recently, several state of the art high end platforms have incorporated FPGAs for application acceleration. This talk explores optimizations for accelerating linear algebra computations on such systems. We develop algorithmic optimizations for such systems and demonstrate the suitability of FPGAs for floating point intensive computations. We discuss the design of a BLAS library for such systems an... View full abstract»

    We have developed an intelligent tutoring system coupled with a virtual laboratory, which constitute a semi-open learning environment. This environment provides the student with the opportunity to learn through exploration within a virtual laboratory, while achieving the expected learning objectives. The key element of this environment is a novel representation for the student model based on proba... View full abstract»

    The PINAS platform provides support to collaboratively and consistently produce shared documents in the Web environment. Such documents may include possible costly multimedia resources, whose management raises important issues due to the constraints imposed by Web technology. In this paper, we present a flexible service for distributing shared Web documents across authoring group sites. To carry o... View full abstract»

    The aging of the population is a phenomenon faced by most nations. Growing old is often accompanied of a loss of close companionship which has been shown may aggravate the cognitive impairment of elders. From a qualitative study, key issues emerged regarding unmet needs of elders communication that we propose to address with Web-based technology. We decided to create an electronic family newspaper...

    The present paper describes the application called ICATIANI, developed to aid hearing impaired children in the acquisition of speech The system supports the practice of vowels, diphthong and basic vocabulary. An animated character "Baldi" pronounces slowly and asks the student to speak, and if the utterance is correctly recognized, Baldi smiles otherwise he makes a sad face and asks the child to t...

  • Visualizing hierarchies and collection structures with fractal trees

    Publication Year: 2005 , Page(s): 31 - 40
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (280 KB) |  | HTML iconHTML  

    This paper addresses the need for better information access to digital library collections. Without proper visualization tools, organizational and structural information is often lost or suppressed by digital library interfaces. We discuss a 2D fractal tree visualization tool that can be used to more accurately present the structure, organization and interrelation of collection metadata. View full abstract»

    The virtual 3D models of human organs in surgery simulation must reproduce the complex viscoelastic deformable behavior of living soft tissue during interaction with virtual surgical tools. Collision detection is a crucial task for modelling and real-time simulation of surgical interactions. Few techniques for collision detection between moving bodies that involve tissue cutting and deformations h... View full abstract»

    Recent advances in communication networks and cryptographic techniques have made possible to consider online voting systems as a feasible alternative to conventional elections. Until today several protocols for electronic voting have been proposed, unfortunately only a few of them have been implemented in an end-to-end fully functional system. In this paper, we present a secure electronic voting s... View full abstract»

  • Supporting quality of privacy (QoP) in pervasive computing

    Privacy might be the greatest barrier to the long-term success of pervasive or ubiquitous computing (ubicomp). The invisibility of embedded computing devices has made it easier to collect and use information about individuals without their knowledge. Sensitive and private information might be stored for long periods of time and appear anywhere at anytime. Thus, a cost, in the form of privacy, migh... View full abstract»

  • Combining structural and textual contexts for compressing semistructured databases

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (224 KB) |  | HTML iconHTML  

    We describe a compression technique for semistructured documents, called SCMPPM, which combines the prediction by partial matching technique with structural contexts model (SCM) technique. SCMPPM takes advantage of the context information usually implicit in the structure of the text. The idea is to use a separate PPM model to compress the text that lies inside each different structure type (e.g.,... View full abstract»

    This paper describes SKIMA, a mediation system that gives transparent access to heterogeneous and distributed sources considering their semantics and the semantics of application requirements. It is based on a pivot model that abstracts concepts and semantic relations based on the SHIQ(D) description logic by Horrocks et al. (2000). We use this model to represent application domains and source con... View full abstract»

    LZW is a lossless data compression algorithm which has been incorporated as the standard of the Consultative Committee on International Telegraphy and Telephony. In addition, LZW is used to create GIF, TIFF and PDF files. In this paper, we propose an improvement to LZW using ideas from sequential pattern mining. The goal of this area is to find all the maximal frequent sequences (MFSs) which are s... View full abstract»

    Data warehouses integrate information from several data sources. Their main goal is to offer an efficient access to data sets and to enable users to make better and faster decisions. In this work, we present our proposition for the management, storage and visualization of a data warehouse (current and historical) in a medical environment using bitemporal schema versions. Changes in data sources co... View full abstract»
