Activity recognition using temporal evidence theory

McKeever, Susan ; Ye, Juan ; Coyle, Lorcan ; Bleakley, Chris ; Dobson, Simon (IOS Press, 2010)

The ability to identify the behavior of people in a home is at the core of Smart Home functionality. Such environments are equipped with sensors that unobtrusively capture information about the occupants. Reasoning mechanisms ...
Adapting and Parameterising Auditory Icons for use in a Synthetic Musical Instrument

Phelan, Cormac ; Bleakley, Chris ; Cummins, Fred (The Institution of Engineering and Technology., 2009-06-10)

In this paper we describe the adaptation and parameterization of environmental auditory event structures for use in a real-time musical synthesizer. In doing so, we have developed a new software musical instrument based ...
Design and Implementation of an Indoor Ultrasonic Communication System

Ballal, Tarig ; Saad, Mohamed M. ; Bleakley, Chris (The Institution of Engineering and Technology, 2011-06-22)

In this paper, an indoor communication system using ultrasonic signals is described. The system uses differential binary phase-shift keying (DBPSK) for transmitting binary data as a part of an indoor positioning system. A ...
Efficient Concurrent Error Detection and Correction of Soft Errors in NTT-based Convolutions

O'Donnell, Anne ; Bleakley, Chris ; Reviriego, P. ; Maestro, J.A. (The Institution of Engineering and Technology, 2009-06)

A system for soft error detection and correction is proposed for digital Integrated Circuit (IC) implementation of convolution. The convolution is implemented in a Residue NumberSystem using Fermat Number Theoretic Transforms. ...
High-precision robust broadband ultrasonic location and orientation estimation

Gonzalez-Hernandez, Juan ; Bleakley, Chris (IEEE, 2009-10-21)

This paper presents an indoor broadband ultrasonic system for estimation of a mobile device’s 3-D location and three-axis orientation using beacons. It presents the first implementation and characterization of a real ...
Hybrid Bayesian Approach for Fusing Range-based and Sourceless Localization Estimates Under Non-Stationary Observability

Yadav, Nagesh ; Bleakley, Chris (IEEE, 2012-09-06)

The paper proposes a hybrid Bayesian approach for multi-sensor data fusion for 3D localization. The approach addresses the problem of fusing range-based and sourceless localization estimates under conditions of varying ...
Increasing the MTU size for Energy Efficiency in Ethernet

Reviriego, P. ; Sanchez-Macian, A. ; Maestro, J.A. ; Bleakley, Chris (Institution of Engineering and Technology, 2010-06-23)

The commonly used Maximum Transfer Unit (MTU) on the Internet has remained unchanged for many years at around 1500 bytes due mainly to backward compatibility issues. This is in contrast with link data rate, which has ...
A Novel Concurrent Error Detection Technique for the Fast Fourier Transform

Reviriego, P. ; Bleakley, Chris ; Maestro, J.A. (The Institution of Engineering and Technology, 2012-06)

A novel Concurrent Error Detection technique for the Fast Fourier Transform (FFT) is proposed in this paper. The technique is similar to the conventional Sum of Squares (SOS) approach but is of lower computational complexity. ...
Robust High Accuracy Ultrasonic Range Measurement System

Saad, Mohamed M. ; Bleakley, Chris ; Dobson, Simon (IEEE, 2011-10)

This paper presents a novel method for ultrasonic range estimation. The method uses a wideband frequency-hop spread spectrum ultrasonic signal to increase robustness to noise and reverberation. The method applies ...
Two Stage Kalman Filtering for Position Estimation Using Dual Inertial Measurement Units

Yadav, Nagesh ; Bleakley, Chris (IEEE, 2011-10-28)

Herein a two stage Kalman filter based algorithm is proposed for processing of Inertial Measurement Unit (IMU) data to obtain accurate position estimation over a short period of time. The proposed algorithm uses a novel ...
Wearable Absolute 6 DOF Exercise Training System for Post Stroke Rehabilitation

Yadav, Nagesh ; Bleakley, Chris ; Lennon, Olive (Dublin City University, 2010-09-02)

This paper introduces a multidisciplinary research effort to design an interactive, real time system to assist rehabilitation of stroke patients. The proposed system aims to help stroke survivors with limited mobility to ...
