TL;DR: The authors introduce the contour spectrum, a user interface component that improves qualitative user interaction and provides real-time exact quantification in the visualization of isocontours.
Abstract: We introduce the contour spectrllm, a user interface component that improves qualitative user interaction and provides real-time exad quantification in the visualization of isoconlours. The contour spectrum is a signature consisting of a variety of scalar data and conlour attributes, computed over the range of scalar values wE!R. We explore the use of surface area, volume, and gradient integral of the contour that are shown to be univariate B-spline functions of the scalar value w for multi-dimensional unstructured triangulal' grids. These quantitative propcrties arc calculated in real-time and presented to the user as a collection of signature graphs (plots of functions of w) to assist in selecting relevant isovalues Wo for informative visualization. For timevarying data, these quantitativc properties can also be computed over time, and displaycd using a 2D interface, giving the user an overview of the time-varying function, and allowing interaction in both isovalue and timestep. The effectiveness of the current system and potential extensions are discussed.

TL;DR: The Mobyle system is designed to provide a flexible and usable Web environment for defining and running bioinformatics analyses that embeds simple yet powerful data management features that allow the user to reproduce analyses and to combine tools using a hierarchical typing system.
Abstract: Motivation: For the biologist, running bioinformatics analyses involves a time-consuming management of data and tools. Users need support to organize their work, retrieve parameters and reproduce their analyses. They also need to be able to combine their analytic tools using a safe data flow software mechanism. Finally, given that scientific tools can be difficult to install, it is particularly helpful for biologists to be able to use these tools through a web user interface. However, providing a web interface for a set of tools raises the problem that a single web portal cannot offer all the existing and possible services: it is the user, again, who has to cope with data copy among a number of different services. A framework enabling portal administrators to build a network of cooperating services would therefore clearly be beneficial.
Results: We have designed a system, Mobyle, to provide a flexible and usable Web environment for defining and running bioinformatics analyses. It embeds simple yet powerful data management features that allow the user to reproduce analyses and to combine tools using a hierarchical typing system. Mobyle offers invocation of services distributed over remote Mobyle servers, thus enabling a federated network of curated bioinformatics portals without the user having to learn complex concepts or to install sophisticated software. While being focused on the end user, the Mobyle system also addresses the need, for the bioinfomatician, to automate remote services execution: PlayMOBY is a companion tool that automates the publication of BioMOBY web services, using Mobyle program definitions.
Availability: The Mobyle system is distributed under the terms of the GNU GPLv2 on the project web site (http://bioweb2.pasteur.fr/projects/mobyle/). It is already deployed on three servers: http://mobyle.pasteur.fr, http://mobyle.rpbs.univ-paris-diderot.fr and http://lipm-bioinfo.toulouse.inra.fr/Mobyle. The PlayMOBY companion is distributed under the terms of the CeCILL license, and is available at http://lipm-bioinfo.toulouse.inra.fr/biomoby/PlayMOBY/.

TL;DR: The Information and Application Distribution System (IADS) as discussed by the authors is an example of a system that allows the user's local computer to automatically set up a user interface to connect with a central controller which facilitates interaction and introduction between and among users.
Abstract: An Information and Application Distribution System (IADS) is disclosed. The IADS operates, in one embodiment, to distribute, initiate and allow interaction and communication within like-minded communities. Application distribution occurs through the transmission and receipt of an “invitation application” which contains both a message component and an executable component to enable multiple users to connect within a specific community. The application object includes functionality which allows the user's local computer to automatically set up a user interface to connect with a central controller which facilitates interaction and introduction between and among users.

01 Jul 1992TL;DR: New techniques to design physically based, goal directed motion of synthetic creatures are described and an interactive framework for specifying constraints and objectives for the motion, and for guiding the numeric solution of the optimization problem is developed.
Abstract: This paper describes new techniques to design physically based, goal directed motion of synthetic creatures. More specifically, it concentrates on developing an interactive framework for specifying constraints and objectives for the motion, and for guiding the numericrd solution of the optimization problem thus defined. The ability to define, modify and guide constrained spacetime problems is provided through an interactive user interface. Innovations that are introduced include, (1) the subdivision of spacetime into discrete pieces, or Spacetime Windows, over which subproblems can be formulated and solved, (2) the use of cubic B-spline approximation techniques to define a C2 function for the creature’s time dependent degrees of freedom, (3) the use of both symbolic and numerical processes to construct and solve the constrained optimization problem, and (4) the ability to specify inequality and conditional constraints. Creatures, in the context of this work, consist of rigid links connected by joints defining a set of generalized degrees of freedom. Hybrid symbolic and numeric techniques to solve the resulting complex constrained optimization problems are made possible by the special structure of physically based models of such creatures, and by the recent development of symbolic algebraic languages. A graphical user interface process handles communication between the user and two other processes; one devoted to symbolic differentiation and manipulation of the constraints and objectives, and one that performs the iterative numerical solution of the optimization problem. The user interface itself provides both high and low level definition of, interaction with, and inspection of, the optimization process and the resulting animation. Implementation issues and experiments with the Spacetime Windows system are discussed,

TL;DR: The Ptolemy project studied heterogeneous modeling, simulation, and design of concurrent systems, particularly those that mix technologies including, for example, analog and digital electronics, hardware and software, and electronics and mechanical devices.
Abstract: : The Ptolemy project studied heterogeneous modeling, simulation, and design of concurrent systems. The focus is on embedded systems, particularly those that mix technologies including, for example, analog and digital electronics, hardware and software, and electronics and mechanical devices (including MEMS, microelectromechanical systems). The focus is also on systems that are complex in the sense that they mix widely different operations such as signal processing, feedback control, sequential decision making, and user interfaces.
