Simulation Model To Investigate Flexible Workload Management For Healthcare And Servicescape Environment, Michael Thorwarth, Paul Harper, Amr Arisha
Simulation Model To Investigate Flexible Workload Management For Healthcare And Servicescape Environment, Michael Thorwarth, Paul Harper, Amr Arisha
Conference papers
High demand and poor staffing conditions cause avoidable pressure and stress among healthcare personnel which results in burnout symptoms and unplanned absenteeism which are hidden cost drivers. The work environment within an emergency department is commonly arranged in a flexible workload which is highly dynamic and complex for the outside observer. Using detailed simulation modeling within structured modeling methods, a comprehensive model to characterize the nurses' time utilization in such flexible dynamic workload environment was investigated. The results have been used to derive a generalized analytic expression that describes certain settings that lead to an instable queuing system with serious …

A Bandwidth Aware Modification To The Dsr Routing Protocol For Wireless Mesh Networks, Mustafa Ramadhan, Mark Davis
A Bandwidth Aware Modification To The Dsr Routing Protocol For Wireless Mesh Networks, Mustafa Ramadhan, Mark Davis
Conference papers
This work proposes a bandwidth aware cross-layer modification to the DSR routing protocol. We include the Access Efficiency Factor (AEF) parameter in addition to the hop-count in the routing discovery mechanism. AEF is a measure to the local availability of bandwidth at a node. Employing the AEF as a metric in the routing discovery mechanism attempts to avoid routing through a congested area in the network. In this modification, we impose a limit on the hop-count in order to control the delay time in the network. The path selection procedure operates by finding a path with the highest minimum AEF …

A Study Of Current Practice Of Corporate Social Responsibility (Csr) And An Examination Of The Relationship Between Csr And Financial Performance Using Structural Equation Modelling (Sem), Lorraine Sweeney
Doctoral
There has been a significant increase in interest in CSR in recent years (Gulyas, 2009; McGehee et al, 2009) and it is regarded as an important topic for research (Burton and Goldsby, 2009). Not only has this topic received academic attention but it is becoming a mainstream issue for many organisations (Renneboog et al, 2008; Nijof and Brujin, 2008). However, it has been noted that research on CSR in SMEs is quite scant (Burton and Goldsby, 2008; Cilberti et al, 2008). A second area of literature that remains unresolved is the relationship between CSR and financial performance (Park and Lee, …

Singlemode-Multimode-Singlemode Optical Fibre Structures For Optical Sensing, Agus Muhamad Hatta
Doctoral
This thesis describes theoretical and experimental investigations on all-fibre multimode interference (MMI) devices using a singlemode-multimode-singlemode (SMS) fibre structure for use as a new type of edge filter for a ratiometric wavelength measurement system and as novel stand alone sensors. The use of two edge filters, so called X-type edge filters based on SMS fibre structures in a ratiometric wavelength measurement system is proposed and demonstrated. The use of X-type edge filters can improve the resolution and accuracy of wavelength measurement compared to the use of one edge filter in a conventional ratiometric system. Several aspects of the SMS edge …
Figurational Dynamics And Parliamentary Discourses Of Living Standards In Ireland, Paddy Dolan
Figurational Dynamics And Parliamentary Discourses Of Living Standards In Ireland, Paddy Dolan
Articles
While the concept of living standards remains central to political debate, it has become marginal in sociological research compared to the burgeoning attention given to the topic of consumer culture in recent decades. However, they both concern how one does and should consume, and, indeed, behave at particular times. I use the theories of Norbert Elias to explain the unplanned but structured (ordered) changes in expected standards of living over time. This figurational approach is compared to other alternative explanations, particularly those advanced by Bourdieu, Veblen and Baudrillard. Though these offer some parallels with Elias’s theories, I argue that consumption …
Electromagnetic Scattering Solutions For Digital Signal Processing, Jonathan Blackledge
Electromagnetic Scattering Solutions For Digital Signal Processing, Jonathan Blackledge
Other resources
Electromagnetic scattering theory is fundamental to understanding the interaction between electromagnetic waves and inhomogeneous dielectric materials. The theory unpins the engineering of electromagnetic imaging systems over a broad range of frequencies, from optics to radio and microwave imaging, for example. Developing accurate scattering models is particularly important in the field of image understanding and the interpretation of electromagnetic signals generated by scattering events. To this end there are a number of approaches that can be taken. For relatively simple geometric configurations, approximation methods are used to develop a transformation from the object plane (where scattering events take place) to the …

The Ceecs’ Banking System: A Risk Study During The Global Financial Crisis, Bernadette Andreosso-O'Callaghan, Lucia Morales, Valentina Tarkovska
Conference papers
We consider operational risk and market integration in the banking system of the Central and East European Countries’ (CEECs). The analysis provides an interesting framework in relation to the effects of the global financial crisis in some European emerging banks. We implement an econometric model that takes into account the level of integration of these banks in relation to a number of most developed institutions, which are represented by the Dow Jones STOXX 600 index, with the objective of analyzing how this could be impacting the level of operational risk in the region. This paper provides new evidence that links …
Microwave-Assisted Synthesis Of Zno Micro-Javelins, Suresh Pillai, Declan Mccormack, John M. Kelly, Sibu C. Padmanabhan
Microwave-Assisted Synthesis Of Zno Micro-Javelins, Suresh Pillai, Declan Mccormack, John M. Kelly, Sibu C. Padmanabhan
Articles
The microwave (MW)-assisted formation of ZnO micro-javelins from zinc nitrate and urea in aqueous solution is described. The particles (named as ‘micro-javelins’ because of their high aspect ratio and needle-like tips) grow hexagonally with well-defined facets in the h0110i direction and pointed tips in (0001) direction. Powder X-ray diffraction patterns show the appearance of a strikingly dominant (1000) orientation. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) investigations reveal the morphological evolution of these hexagonal ZnO particles with time. The effect of precursor concentrations, counterion type andMWirradiation power and their consequent influence on pH and Zn2+ ion concentration are …

To Document Or Not To Document, That Is The Question? Use Of The Participatory Archive Model For A Residential Artist’S Centre, Yvonne Desmond
Conference papers
Men of genius really are doing most when they work least, as they are thinking out ideas and perfecting the conceptions which they will subsequently carry out with their hands.’ (Leonardo da Vinci) There is a romantic notion that regards all forms of Art as emanating from the gods and artists as the mere conduits for this divine inspiration. This research project disavows such notions and instead is predicated on the basis that all artists are skilled practitioners of their craft. Research into the areas of tacit knowledge and visual intelligence indicate that the making of art is an experiential …

Context Aware Smart Classroom For Real Time Configuration Of Computer Rooms, Paula Kelly, Peter Daly, Ciaran O'Driscoll
9th. IT & T Conference
The Context Aware Smart Classroom (CASC) is a classroom that responds to lecturers and student groups based on preset policies and the lecture timetables. CASC has been enhanced in two ways: initially to support the real-time software configuration of computers as required by specific laboratory activities; secondly to improve the decision making using knowledge engineering techniques. This paper outlines the design, implementation and evaluation of an enhanced system, CASC for Software Configuration (CASC–SC). Context aware environments respond in a pseudo-intelligent manner depending on the identity of occupants, particular location, desired activity and specific time. With the pervasive nature of personal …

Sensing Learner Interest Through Eye Tracking, Haolin Wei, Arthir-Nicolae Moldovan, Cristina Muntean
9th. IT & T Conference
Due to the rapidly growing of the amount of information, a stronger need emerges for efficient and flexible strategies for personalisation of the educational content. E-learning systems are very helpful for learners, however, people differ in knowledge level, learning styles and may seek for different information when they access web based e-learning systems. Therefore, content adapted to the user’s needs should be supported by the e-learning systems. In this paper we introduce a new e-learning environment that makes use of eye tracking mechanism to follow learner interest in certain topics and to perform content personalisation. The framework of the e-learning …

Vocate: Auditory Interfaces For The Lok8 Project, John Mcgee, Charlie Cullen
9th. IT & T Conference
The auditory modality has a number of unique advantages over other modalities, such as a fast neural processing rate and focus-independence. As part of the LOK8 project’s aim to develop location-based services, the Vocate module will be seeking to exploit these advantages to augment the overall usability of the LOK8 interface and also to deliver scalable content in scenarios where the user may be in transit or requires focus-independence. This paper discusses these advantages and outlines three possible approaches that the Vocate module may take within the LOK8 project: speech interfaces, auditory user interfaces, and sonification.

Comparison Of Feature Classification Algorithm For Activity Recognition Based On Accelerometer And Heart Rate Data, Dominic Maguire, Richard Frisby
9th. IT & T Conference
This paper describes a project to compare two feature classification algorithms used in activity recognition in relation to accelerometer and heart rate data. Data was collected from six male and female subjects using a single tri-axial accelerometer and heart monitor attached to each subject’s dominant thigh. Subjects carried out eight activities and the data was labelled semi-automatically. Features (mean, standard deviation, energy, correlation and mean heart rate) were extracted from the data using a window of 256 (3.4 seconds) and an overlap of 50%. Two classifers, k-NN and J48, were evaluated for activity recognition with 10-fold validation with k-NN (k …

Voshm: A Velocity Optimized Seamless Handover Mechanism For Wimax Networks, Chi Ma, Enda Fallon, Yansong Qiao
9th. IT & T Conference
For seamless handover in heterogeneous wireless networks, service continuity and minimal handover disruption time are the primary requirements. The emerging Media Independent Handover (MIH) standard proposes to address these requirements through the introduction of link performance prediction features. In particular the MIH Event Service introduces a Link_Going_Down event which utilizes L2 performance characteristics to trigger predictive events. While the MIH standard proposes a framework by which L2 events can be communicated to the upper layer, it does provide detail on the performance characteristics which trigger these events. In this paper, we design a MIH based Velocity Optimized Seamless Handover Mechanism …

Tracker: Indoor Positioning For The Lok8 Project, Viacheslav Filonenko, James Carswell
9th. IT & T Conference
Spatial awareness is identified as a key feature of today’s mobile devices. While outdoor navigation has been accessible and broadly used for some time already with the help of GPS, indoor positioning has not yet made it into mainstream life. GPS and other GNSS systems offer accuracy of a scale different to that required for efficient indoor navigation. This research aims to investigate how a number of sensors such as a Digital Compass, Bluetooth and Accelerometer may be combined to calculate device position and orientation to perform directional querying in a spatial database. These three technologies were chosen because they …

An Improved Camshift Algorithm For Target Tracking In Video Surveillance, Chunrong Zhang, Yuansong Qiao, Enda Fallon, Chiangqiao Xu
9th. IT & T Conference
Target tracking in a cluttered environment remains a challenging research topic. The task of target tracking is a key component of video surveillance and monitoring systems. In this paper, we present an improved CamShift algorithm for tracking a target in video sequences in real time. Firstly, a background-weighted histogram which helps to distinguish the target from the background and other targets is introduced. Secondly, the window size is calculated to track the target as its shape and orientation change. Finally, we use a Kalman Filter to avoid being trapped by a local maximum. The introduction of the Kalman Filter also …

Examining The Inseparability Of Enterprise And Strategy Discourse, Brendan O'Rourke
Examining The Inseparability Of Enterprise And Strategy Discourse, Brendan O'Rourke
Conference papers
Small owner-managed firms are an interesting site in which to examine the deployment of strategy discourse. On the one hand, small firms offer a location where the holistic nature of strategy (Clegg et al., 2004:24; Liedtka, 1998:122; Lilley,2001: 75) is more likely to feature in daily practice On the other hand, owner-managed firms lack a key reason for the original emergence of the strategy discourse i.e. strategy as a discourse of accountability by professional managers to shareholders (Knights & Morgan, 1991). Small firm owner-managers are the ideological heroes of the enterprise discourse (Carr, 2000:101). This work looks at how owner-managers …
