Towards using prosody to scaffold lexical meaning in robots
(Institute of Electrical and Electronics Engineers (IEEE), 2011)We present a case-study analysing the prosodic contours and salient word markers of a small corpus of robot-directed speech where the human participants had been asked to talk to a socially interactive robot as if it were ... -
Empowerment for continuous agent-environment systems
(2011-02)This article develops generalizations of empowerment to continuous states. Empowerment is a recently introduced information-theoretic quantity motivated by hypotheses about the efficiency of the sensorimotor loop in ... -
Five Weeks in the Robot House : Exploratory Human-Robot Interaction Trials in a Domestic Setting
(Institute of Electrical and Electronics Engineers (IEEE), 2009)This paper presents five exploratory trials investigating scenarios likely to occur when a personal robot shares a home with a person. The scenarios are: a human and robot working on a collaborative task, a human and robot ... -
The boy-robot should bark! : Children's impressions of agent migration into diverse embodiments
(2009)This paper presents results from a series of focused group discussions with a sample consisting of approximately 180 children during which views and opinions regarding agents migrating between different embodiments were ... -
Evaluating extrovert and introvert behaviour of a domestic robot : a video study
(Institute of Electrical and Electronics Engineers (IEEE), 2008)Human-Robot Interaction (HRI) research is here presented into social robots that have to be able to interact with inexperienced users. In the design of these robots many research findings of human-human interaction and ... -
Reducing the cost of robotics software : SAMGAR, a generic modular robotic software communication architecture
(Institute of Electrical and Electronics Engineers (IEEE), 2009)Code reuse in advanced robotics can be problematic due to the wide spectrum of robotic projects and little standardization. Although, in some cases, there are standardisations and tools that can be used, such as YARP, there ... -
Operable Non–Small Cell Lung Cancer : Correlation of Volumetric Helical Dynamic Contrast-enhanced CT Parameters with Immunohistochemical Markers of Tumor Hypoxia
(2012)To assess the relationship between helical dynamic contrast material–enhanced (DCE) computed tomographic (CT) parameters and immunohistochemical markers of hypoxia in patients with operable non–small cell lung cancer (NSCLC) -
Fast mode decision for Hierarchical-B pictures in scalable video coding
(2011-08-01)To decrease the computational complexity of adaptive inter-layer prediction and improve the encoding efficiency in scalable video coding, a mode decision algorithm is proposed by exploiting the part of used candidate modes ... -
Dynamic and scalable storage management architecture for Grid Oriented Storage devices
(2008)Most of currently deployed Grid systems employ hierarchical or centralized approaches to simplify system management. However, the approaches cannot satisfy the requirements of complex Grid applications which involve hundreds ... -
EED: Energy Efficient Disk drive architecture
(2008)Energy efficiency has become one of the most important challenges in designing future computing systems, and the storage system is one of the largest energy consumers within them. This paper proposes an Energy Efficient ... -
Lateral inhibitory networks : Synchrony, edge enhancement, and noise reduction
(Institute of Electrical and Electronics Engineers (IEEE), 2011)This paper investigates how layers of spiking neurons can be connected using lateral inhibition in different ways to bring about synchrony, reduce noise, and extract or enhance features. To illustrate the effects of the ... -
Feature extraction from spectro-temporal signals using dynamic synapses, recurrency, and lateral inhibition
(Institute of Electrical and Electronics Engineers (IEEE), 2010)This paper presents a spiking neural network-based investigation of the issues associated with extraction of onset, offset, and coincidental firing features from spectro-temporal data. Speech samples containing spoken ... -
Delayed switching applied to memristor neural networks
(2012)Magnetic flux and electric charge are linked in a memristor. We reported recently that a memristor has a peculiar effect in which the switching takes place with a time delay because a memristor possesses a certain inertia. ... -
Discriminating angry, happy and neutral facial expression : a comparison of computational models
(Springer Nature, 2009)Recognizing expressions are a key part of human social interaction, and processing of facial expression information is largely automatic for humans, but it is a non-trivial task for a computational system. The purpose of ... -
CSP duality and trees of bounded pathwidth
(2010)We study non-uniform constraint satisfaction problems definable in monadic Datalog stratified by the use of non-linearity. We show how such problems can be described in terms of homomorphism dualities involving trees of ... -
Two new homomorphism dualities and lattice operations
(2011)The study of constraint satisfaction problems definable in various fragments of Datalog has recently gained considerable importance. We consider constraint satisfaction problems that are definable in the smallest natural ... -
CD(4) has bounded width
(2009)We prove that the constraint languages invariant under a short sequence of J\'onsson terms (containing at most three non-trivial ternary terms) are tractable by showing that they have bounded width. This improves the ... -
A Systematic Literature Review on Fault Prediction Performance in Software Engineering
(2012)Background: The accurate prediction of where faults are likely to occur in code can help direct test effort, reduce costs, and improve the quality of software. Objective: We investigate how the context of models, the ... -
A systematic review of theory use in studies investigating the motivations of software engineers
(2009)Motivated software engineers make a critical contribution to delivering successful software systems. Understanding the motivations of software engineers and the impact of motivation on software engineering outcomes could ... -
Models of motivation in software engineering
(2009)Motivation in software engineering is recognized as a key success factor for software projects, but although there are many papers written about motivation in software engineering, the field lacks a comprehensive overview ...
