A new method for representing linguistic quantifications by random sets with applications to tracking and data fusion Tập 2 - Trang 1308-1315 vol.2
W.C. Torrez, D. Bamber, I.R. Goodman, H.T. Nguyen
There is an obvious need to be able to integrate both linguistic-based and
stochastic-based input information in data fusion. In particular, this need is
critical in addressing problems of track association, including cyber-state
intrusions. This paper treats this issue through a new insight into how three
apparently distinct mathematical tools can be combined: "boolean relational
event algebra" (... hiện toàn bộ

Particle filtering for multi-target tracking and sensor management Tập 1 - Trang 474-481 vol.1
A. Doucet, B.-N. Vo, C. Andrieu, M. Davy
In this paper, we present computational methods based on particle filters to
address the multi-target tracking and sensor management problems. We present a
jump Markov model of multi-target systems and an efficient particle filtering
algorithm to perform inference. In addition, we also present a formulation of
the sensor management problem and its solution using particle methods.

Dynamic I/O power management in real-time systems with multiple-state I/O devices Tập 2 - Trang 1588-1595 vol.2
V. Swaminathan, K. Chakrabarty
Power consumption is now an important design parameter for distributed sensor
networks. While dynamic (or software-controlled) power management (DPM) is being
increasingly used as an alternative to inflexible hardware solutions, DPM for
hard real-time systems has received relatively little attention. In particular,
energy-driven I/O device scheduling for real-time systems has received even less

Computable rate of convergence in evolutionary computation Tập 1 - Trang 88-93 vol.1
D.R. Stark, J.C. Spall
The broad field of evolutionary computation (EC)-including genetic algorithms as
a special case-has attracted much attention in the last several decades. Many
bold claims have been made about the effectiveness of various EC algorithms.
These claims have centered on the efficiency, robustness, and ease of
implementation of EC approaches. Unfortunately, there seems to be little theory
to support suc... hiện toàn bộ

General tracking performance description for systems of sensors Tập 1 - Trang 128-134 vol.1
A. Andersson, T.R. Kronhamn
Traditionally, radar or sensor performance is reviewed in terms of detection
ranges and measurement accuracy. Today, when the radar often is a part of a
locally integrated sensor system, which shall cooperate with other sensor
systems, other performance parameters are required for evaluation and comparison
of various solutions. The present paper gives an analysis method for
descriptions of the tra... hiện toàn bộ

Fusion of visual and IR images for concealed weapon detection Tập 2 - Trang 1198-1205 vol.2
Z. Xue, R.S. Blum, Y. Li
Image fusion for concealed weapon detection (CWD) using visual and IR images is
studied. A large set of existing image fusion algorithms are identified and
their performance is compared for the CWD application using quantitative and
qualitative measures.

A variable structure multiple model particle filter for GMTI tracking Tập 2 - Trang 927-934 vol.2
M.S. Arulampalam, N. Gordon, M. Orton, B. Ristic
The problem of tracking ground targets with GMTI sensors has received some
attention in the recent past. In addition to standard GMTI sensor measurements,
one is interested in using non-standard information such as road maps, and
terrain-related visibility conditions to enhance tracker performance. The
conventional approach to this problem has been to use the variable structure IMM
(VS-IMM), which... hiện toàn bộ

Coalitions for distributed sensor fusion Tập 1 - Trang 636-642 vol.1
M. Howard, D. Payton, R. Estkowski
We address the problem of efficient use of communication bandwidth in a network
of distributed sensors. Each sensor node has enough computational power to fuse
its own estimates with those of other nodes using an optimal filter, but message
passing is expensive. The goal is to give each node an identical tactical
picture of the area of interest without compromising target track accuracy. In
the cu... hiện toàn bộ

An interacting automata model for network protection Tập 2 - Trang 1090-1097 vol.2
R. Brooks, N. Orr, J. Zachary, C. Griffin
Malicious network activity is rapidly increasing. To understand and engineer
countermeasures to network attacks, we have developed cellular automata models
of network flow dynamics and associated attacks. We describe the theoretical
development of our model and compare it to existing models of network flow based
on statistical physics. Using our model, we have found empirical evidence that a
