We describe a parallel implementation of a genetic linkage analysis program that achieves good speedups, even for analyses on a single pedigree and with a single starting recombination fraction vector. Our parallel implementation has been run on three diff ...
Multimedia interfaces increase the need for large image databases, supporting the capability of storing and fetching streams of data with strict synchronicity and isochronicity requirements. In order to fulfill these requirements, the GigaView parallel ima ...
Multimedia interfaces increase the need for large image databases, capable of storing and reading streams of data with strict synchronicity and isochronicity requirements. In order to fulfil these requirements, we use a parallel image server architecture w ...
Variable Bit Rate real-time multimedia services like highly compressed video or audio tend to be very sensitive to transmission errors. This paper investigates cell and frame loss as well as delay and timing issues in an ATM-based B-ISDN environment that c ...
In this paper, we discuss a new automatic speech recognition (ASR) approach based on independent processing and recombination of several feature streams. In this framework, it is assumed that the speech signal is represented in terms of multiple input stre ...
In this paper, we present a new rate control mechanism for delay sensitive MPEG-2 video services over ATM networks. The rate control constraints the video bitstream to respect the three negotiated VBR ATM traffic contract parameters modelled by a dual leak ...
Coefficient quantization has peculiar qualitative ef- fects on representations of vectors in R^n with respect to over- complete sets of vectors. These effects are investigated in two settings: frame expansions (representations obtained by forming inner pro ...
Consider a network with an arbitrary topology and arbitrary communication delays, in which congestion control is based on additive-increase and multiplicative-decrease. We show that the source rates tend to be distributed in order to maximize an objective ...
This article presents methods and tools for building parallel applications based on commodity components: PCs, SCSI disks, Fast Ethernet, Windows NT. Chief among these tools is CAP, our computer-aided parallelization tool. CAP generates highly pipelined ap ...
We show the evolution from the earliest frame-by-frame synthetic actors to real-time perceptive actors living in distributed virtual environments or even in the real world. We first compare requirements and methods for frame-by-frame and real-time actors. ...
