On the Design of Ambient Intelligent Systems in the Context of Assistive Technologies
(Springer, 2004)
The design of Ambient Intelligent Systems (AISs) is discussed in the context of assistive technologies. The main issues include ubiquitous communications, context awareness, natural interactions and heterogeneity, which ...

ROM-based FSM implementation using input multiplexing in FPGA devices
(IET Digital Library, 2004-09)
A new approach for ROM implementation of finite state machines (FSMs) is proposed, based on the selection of a subset of inputs in each state using multiplexers. This technique has been applied to different FSM standard ...

On Synthetic AER Generation
(IEEE, 2004-05)
In this paper several software methods for generating synthetic AER streams from images stored in a computer's memory are proposed and evaluated. Evaluation criteria cover execution time, distribution error and how they ...

Supporting Usability and Reusability Based on eLearning Standards
(IEEE Computer Society, 2004)
The IMS-QTI, and other related specifications have been developed to support the creation of reusable and pedagogically neutral assessment scenarios and content, as stated by the IMS Global Learning Consortium. In this ...

Hierarchical Path Search with Partial Materialization of Costs for a Smart Wheelchair
(Springer, 2004)
In this paper, the off-line path planner module of a smart wheelchair aided navigation system is described. Environmental information is structured into a hierarchical graph (H-graph) and used either by the user interface ...

Hardware/software codesign of configurable fuzzy control systems
(Elsevier, 2004)
Fuzzy inference techniques are an attractive and well-established approach for solving control problems. This is mainly due to their inherent ability to obtain robust, low-cost controllers from the intuitive (and usually ...

A parametric formulation of tracking methods: application to chained systems
(IEEE Computer Society, 2004)
When following a path, there are several possibilities attending to the way in which the actual robot state can be related with the whole path. In this work, we formulate different tracking methods on the base that a ...

Performance analysis of single-slave Bluetooth piconets under cochannel interference
(IEEE Computer Society, 2004)
We present an analytical model for single-slave Bluetooth piconets when the coexistence of multiple interfering devices produces collisions. Closed-form expressions for the channel throughput and the mean packet delay are ...

A Precise CMOS Mismatch Model for Analog Design from Weak to Strong Inversion
(IEEE Computer Society, 2004)
A five parameter mismatch model continuos from weak to strong inversion is presented. The model is an extension of a previously reported one valid in the strong inversion region [1]. A mismatch characterization of NMOS ...

Simulation of the Dynamics of Pulsed Pumped Lasers Based on Cellular Automata
(Springer, 2004)
Laser dynamics is traditionally modeled using differential equations. Recently, a new approach has been introduced in which laser dynamics is modeled using two-dimensional Cellular Automata (CA). In this work, we study ...
