Online review systems (ORS) such as TripAdvisor or Yelp collect numeric evaluations from reviewers using interval scales. However, the UI of interval scales differ remarkably across ORS, even though prior research suggests that design cues of the interval scale can bias individual’s interpretation of the scale and thus the numeric evaluations. The impact of the UI on numeric evaluations is part...

This paper addresses the problem of automatic numeric recognition and understanding in spoken language dialogue. We show that accurate numeric understanding in ̄uent unconstrained speech demands maintaining robustness at several di€erent levels of system design, including acoustic, language, understanding and dialogue. We describe a robust system for numeric recognition and present algorithms f...

This paper describes an automated procedure for analysing the significance of each of the many terms in the equations of motion for a serial-link robot manipulator. Significance analysis provides insight into the rigid-body dynamic effects that are significant locally or globally in the manipulator’s state space. Deleting those terms that do not contribute significantly to the total joint torqu...

The article investigates the numeric simulation of two-way aeroelastic processes applied to the experimental phase of a compressor; physical, mathematical, rigid and grid models of the system “gas – rotor – stator” have been worked out; 2 FSI (two-way Fluid-Structure Interaction) calculations have been performed on the evaluation of the interaction between a gas-dynamic flow and a deformable ro...

A significant advantage of multirobot simulation lays on the fact that their physical features and environment can be simulated, and hence, difficulties that spring when managing them are avoided. This paper shows a flexible method for simulating multirobot systems. It provides a simple and non proprietary structure of classes, that can be used as the backbone of complex developments, adapted t...

During a numeric simulation based on the finite element method, the h-refinement of the mesh consists in splitting the elements where an error indicator is higher than a threshold. One major point is that the final mesh must be conformal. When the mesh is defined only by triangles or tetrahedra, the junction between two zones with a different level of refinement has been solved for many years. ...

Abstract— In this paper, new swing-up controller for a threelink underactuated robot using a technique of horizontal bar gymnast is proposed. This controller is designed based on an equivalent center of mass(ECM) of the gymnast and the robot. The ECM of the gymnasts(ECMG) derived by analyzing a video data and a proposed controller is designed in order to realize that the ECM of the robot imitat...

This paper presents a method and preliminary study for estimating the location of vertebrae from uncalibrated bi-planar radiographs. The method uses the axis/angle representation of rotations and exact analytic derivatives for optimising the objective function. Multiple vertebral models are incorporated in a single procedure. Results are shown on both real data in vivo and on simulated data. No...

This paper compares the performance, in terms of convergence rates and precision of the estimates, for six Monte Carlo Simulation sampling methods: Quasi-Monte Carlo using Halton, Sobol, and Faure numeric sequences; Descriptive Sampling, based on the use of deterministic sets and Latin Hypercube Sampling, based on stratified numerical sets. Those methods are compared to the classical Monte Carl...

The real-world application of planning techniques often requires models with numeric fluents. However, these fluents are not directly supported by most planners and heuristics. We describe a family of planning algorithms that takes a numeric planning problem and produces an abstracted representation that can be solved using any classical planner. The resulting abstract plan is generalized into ...
