SUPER is an exploratory project into the next generation of user-DBMS interfaces. Its main objective is to demonstrate that a visual paradigm can lead to powerful and user-friendly interfaces supporting all phases of the database life cycle (i.e. creation, ...
The concepts of object oriented data models aim towards modeling of application objects close to the user's view. Yet developers of applications relying on object oriented database management systems are facing problems resulting from the limitations of ob ...
In a transactional system, an atomic commitment protocol ensures that for any transaction, all data managers agree on the same outcome: commit or abort. A non-blocking atomic commitment protocol enables an outcome to be decided at every correct data manage ...
This article proposes an improvement of existing methods of origin-destination matrix estimation by an explicit use of data describing the structure of the matrix. These data can be obtained from parking surveys. The new model is applied on both illustrati ...
The nature, purpose and assumptions of modeling are discussed. The concepts of "value" and "object" are assessed in this context. Their fundamental nature is compared and different uses are investigated. Various approaches are illustrated with comparative ...
This paper evaluates current object-oriented analysis methods and proposes some possible improvements. We start by describing software requirements definition activities and reviewing the concepts of data modeling and object-orientation. We then identify k ...
The paper describes the "electronic" stiffening of the actuators developed for the articulated boom of JET. Experimental trials on a two joints Boom have confirmed the improvements of speed and reliability that can be achieved. Based on these developments, ...
We propose a new, simple way of constructing elastic tubes which can be used to model the nonlinear elastic properties of large arteries. The tube models are constructed from a silicon elastomer (Sylgard 184, Dow Corning), which exhibits a nonlinear behavi ...
This paper describes a system that recognizes hand-printed digits. The system is based on optimal bounded error matching, a technique already in common use in general-purpose 2D and 3D visual object recognition systems in cluttered, noisy scenes. In this p ...
The purpose of this work is to predict the behaviour of electric devices using superconducting tapes, including the transition of those tapes to the normal state, which implies a typical non linear behaviour. The frequency domain studied is as wide as poss ...
