Designing and evaluating a social gaze-control system for a humanoid robot (2014)
Journal Article

This paper describes a context-dependent social gaze-control system implemented as part of a humanoid social robot. The system enables the robot to direct its gaze at multiple humans who are interacting with each other and with the robot. The attenti...

A mixed-method approach to evoke creative and holistic thinking about robots in a home environment (2014)
Presentation / Conference Contribution

Discovering older adults' perceptions and expectations of domestic care service robots are vital in informing the design and development of new technologies to ensure acceptability and usability. This paper identifies issues that were elicited from o... Read More about A mixed-method approach to evoke creative and holistic thinking about robots in a home environment.

Confirming nasogastric tube position with electromagnetic tracking versus pH or X-ray and tube radio-opacity (2014)
Journal Article

Recent evidence suggests official statistics greatly underestimate the occurrence of complications from misplaced nasogastric (NG) tubes, even when detected. Current methods of confirming tube position do not provide adequate protection from misplace...

The effect of corrugated skins on aerodynamic performance (2014)
Journal Article

Corrugated skins provide a good solution to morphing wings due to their highly anisotropic behavior. If the low stiffness corrugation plane is aligned in the chordwise direction, the airfoil shape change is possible. In contrast to the traditional sm...

Operative time and outcome of enhanced recovery after surgery after laparoscopic colorectal surgery (2014)
Journal Article

Background and Objectives: Combining laparoscopy and enhanced recovery provides benefit to short-term outcomes after colorectal surgery. Advances in training and techniques have allowed surgeons to operate on cases that are technically challenging an... Read More about Operative time and outcome of enhanced recovery after surgery after laparoscopic colorectal surgery.

Nasogastric tube depth: The 'NEX' guideline is incorrect (2014)
Journal Article

© 2014 MA Healthcare Ltd. Misplacing 17-23% of nasogastric (NG) tubes above the stomach (Rollins et al, 2012; Rayner, 2013) represents a serious risk in terms of aspiration, further invasive (tube) procedures, irradiation from failed X-ray confirmati...

Blending moving least squares techniques with NURBS basis functions for nonlinear isogeometric analysis (2014)
Journal Article

IsoGeometric Analysis (IGA) is increasing its popularity as a new numerical tool for the analysis of structures. IGA provides: (i) the possibility of using higher order polynomials for the basis functions; (ii) the smoothness for contact analysis; (i...

Effect of mental challenge induced by movie clips on action potential duration in normal human subjects independent of heart rate (2014)
Journal Article

Background-Mental stress and emotion have long been associated with ventricular arrhythmias and sudden death in animal models and humans. The effect of mental challenge on ventricular action potential duration (APD) in conscious healthy humans has no...

Experimental investigation into the performance of shallow aeroengine off-takes (2014)
Presentation / Conference Contribution

Copyright © 2014 by Rolls-Royce plc. Oil removal (scavenge) from aeroengine bearing chambers is an ongoing challenge for aeroengine designers. Effective scavenging of oil is necessary to avoid excessive heat generation, degradation of oil properties...

Observer design for a class of nonlinear systems subject to unknown inputs (2014)
Presentation / Conference Contribution

© 2014 EUCA. We consider a novel method to design an observer for a class of nonlinear discrete-time systems with unknown inputs. Based on Lyapunov functional, we derive a sufficient condition for existence of the designed observer which requires sol...
