Semantic Virtual Environments with Adaptive Multimodal Interfaces

We present a system for real-time configuration of multimodal interfaces to Virtual Environments (VE). The flexibility of our tool is supported by a semantics-based representation of VEs. Semantic descriptors are used to define interaction devices and virt ...

Ambulatory gait analysis in Parkinson's Disease: Application of a novel method based on kinematics sensors

Kamiar Aminian, Catherine Dehollain, Arash Salarian

Summary: Using our ambulatory monitoring system, ASUR, 13 Parkinsonian patients were monitored for periods of up to 5 hours while they were free to perform activities at will. Every one hour patients did a UPDRS test as the clinical assessment. During the ...

Stable Real-Time Interaction Between Virtual Humans and Real Scenes

Daniel Thalmann, Pascal Fua, Vincent Lepetit, Michal Ponder

We present an augmented reality system that relies on purely passive techniques to solve the real-time registration problem. It can run on a portable PC and does not require engineering of the environment, for example by adding markers. To achieve this res ...

A parallel implementation of NEC for the analysis of large structures

Marcos Rubinstein, Abraham Rubinstein

We present a new, parallel version of the numerical electromagnetics code (NEC). The parallelization is based on a bidimensional block-cyclic distribution of matrices on a rectangular processor grid, assuring a theoretically optimal load balance among the ...

Energy management in an airflow regulator

Yves Perriard, Frédéric Bonvin

Artificial respirators use an electric source of energy to supply the various active components which control the airflow. A portable or autonomous respirator (emergency, war, ambulance, etc), needs a battery or an energy container to be supplied with grea ...

Dynamic power management for portable systems

Giovanni De Micheli, Luca Benini

Portable systems require long battery lifetime while still delivering high performance. Dynamic power management (DPM) policies trade off the performance for the power consumption at the system level in portable devices. In this work we present the time-in ...

Wisconsin Wind Tunnel II: A Fast and Portable Parallel Architecture Simulator

Babak Falsafi, James Richard Larus, David Wood

The design of future parallel computers requires rapid simulation of target designs running realistic workloads. These simulations have been accelerated using two techniques: direct execution and the use of a parallel host. Historically, these techniques h ...

The Tempest Approach to Distributed Shared Memory

James Richard Larus, David Wood

This paper summarizes how distributed shared memory (DSM) can be both efficiently and portably supported by the Tempest interface. Tempest is a collection of mechanisms for communication and synchronization in parallel programs. These mechanisms provide co ...

Fine-grain access control for distributed shared memory

Babak Falsafi, James Richard Larus, David Wood

The paper discusses implementations of fine-grain memory access control, which selectively restricts reads and writes to cache-block-sized memory regions. Fine-grain access control forms the basis of efficient cache- coherent shared memory. The paper focus ...

Design and analysis techniques for dynamic current mirrors

Today's world of electronics becomes more and more digital and therefore CMOS becomes the dominant technology. A CMOS process compared to a bipolar process offers several advantages, mainly a low power consumption which is important for portable systems po ...
