Calibration of an orientation sensor for freehand 3D ultrasound and its use in a hybrid acquisition system
(Biomedical Engineering OnLine, 2008-01-24)
Abstract Background Freehand 3D ultrasound is a powerful imaging modality with many potential applications. However, its reliance on add-on position sensors, which can be expensive, obtrusive and difficult to calibrate, ...
Minimizing Detection Probability Routing in Ad Hoc Networks Using Directional Antennas
(2009-06-08)
In a hostile environment, it is important for a transmitter to make its wireless transmission invisible to adversaries because an adversary can detect the transmitter if the received power at its antennas is strong enough. ...
Particle Filtering for Joint Symbol and Code Delay Estimation in DS Spread Spectrum Systems in Multipath Environment
(2004-11-07)
We develop a new receiver for joint symbol, channel characteristics, and code delay estimation for DS spread spectrum systems under conditions of multipath fading. The approach is based on particle filtering techniques and ...
Particle Filtering Applied to Musical Tempo Tracking
(2004-11-07)
This paper explores the use of particle filters for beat tracking in musical audio examples. The aim is to estimate the time-varying tempo process and to find the time locations of beats, as defined by human perception. ...

The P3 platform: an approach and software system for developing diagrammatic model-based methods in design research
(Proceedings of the 17th International Conference on Engineering Design' ICED '09, Vol.1: Design ProcessesProceedings of the 17th International Conference on Engineering Design' ICED '09, Vol.1: Design Processes, 2009-08-24)
Many issues in design and design management have been explored by building models which capture the relationships between different aspects of the problem at hand. These models require computer support to construct and ...
Design project planning, monitoring and re-planning through process simulation
(Proceedings of ICED'09 - Design ProcessesProceedings of ICED'09 - Design Processes, 2009-08-24)
Effective management of design schedules is a major concern in industry, since timely project delivery can have a significant influence on a company’s profitability. Based on insights gained through a case study of planning ...
Modelling iteration in engineering design
(16th International Conference on Engineering Design (ICED'07)16th International Conference on Engineering Design (ICED'07), 2007-08-28)
This paper examines design iteration and its modelling in the simulation of New Product Development (NPD) processes. A framework comprising six perspectives of iteration is proposed and it is argued that the importance of ...
On the playability of stringed instruments
(University of CambridgeDepartment of EngineeringTrinity College, 2004-07-13)
As first noticed by Helmholtz, strings vibrate in a “V-shape” when they are bowed correctly and a full tone is produced, where the vertex of the “V” shuttles back and forth along the visible envelope of the string’s motion. ...
External prestressed carbon fiber-reinforced polymer straps for shear enhancement of concrete
(American Society of Civil EngineersJournal of Composites for Construction (ASCE), 2002)
The use of fiber-reinforced polymers (FRPs) for the strengthening and repair of existing concrete structures is a field with tremendous potential. The materials are very durable and, hence, ideally suited for use as external ...
