Archetype alignment: A two-level driven semantic matching approach to interoperability in the clinical domain

Archetype alignment: A two-level driven semantic matching approach to interoperability in the clinical domain
(2009)
Berry, Damon; Bisbal, Jesus
Abstract:
Semantic interoperability between electronic health record systems and other information systems in the health domain implies agreement about the structure and the meaning of the information that is communicated. There are still a number of similar but different EHR system approaches. Some of the newer approaches adopt the two-layer model approach where a generic reference model is constrained by archetypes into valid clinical concepts which can be exchanged. The meaning of the concepts that are represented by an archetype can be conveyed by embedding codes from a commonly recognised terminology at appropriate points in the archetype. However, as the number of archetypes multiply it will become necessary to match archetypes from different sources to facilitate interoperability. This paper describes an approach that supports semantic interoperability between heterogeneous two-level health information systems by identifying similarities between archetypes. The approach identifies rel...

The Application of Fuzzy Logic in Determining Linguistic Rules and Associative Membership Functions for the Control of a Manufacturing Process
(2011)
Foley, Marcus; McGrory, John
Abstract:
<p>Fuzzy logic is a form of multi-valued logic derived from fuzzy set theory. Its methodology aims to provide a definitive solution from information that may be construed as ambiguous, imprecise or noisy. Classical set theory studies the properties of sets, while fuzzy set theory investigates the degree to which an element can be related to a set. The aim of this project is to develop a control strategy for a specific technical challenge relating to the food processing sector based on the deployment of fuzzy logic control concepts. Specifically, in this paper the author is concerned with the ability to control the density input of a variable feed product stream by automatically adjusting the „thermo pressure‟ & „feed flow‟ within desired limits. For the purpose of this study, the expert knowledge of both senior automation engineers and process operators was procured in order to develop an understanding of the dynamics and the limitations of the manufacturing process. The f...

The Integration of Smart Meters Into Electrical Grids to Ensure Maximum Benefit for Consumers, Generators and Network Operators.
(2010)
Bean, Tom; McGrory, John
Abstract:
<p>The term “smart metering” has been used in many project descriptions and publications produced by utility companies (e.g. gas, water and electricity), conference papers and journal papers, but the true meaning of the term has been fudged. Does smart metering signify rapid recording of data (i.e. data logger) or does it give totals (e.g. maximum, minimum and average), as neither of these are truly “Smart” or “Intelligent” virtues in themselves, or is there some additional role that needs to be explored. This dissertation examines the “smart metering” idiom jointly from energy supplier, grid manager and consumer perspectives and formulates a detailed model of the interfaces that are currently being touted as necessary for realising a smart system. Other aspects such as infrastructure, networking of data, ownership, location etc are also explored. Using a base model of the existing approach, this research shows where true “Smart” or “Intelligent” virtues could be incorporated....

Development of a Tool for Windfarm Site Analysis in Electrical Networks with High Levels of Wind Power Generation
(2010)
Carroll, Edward; McGrory, John
Abstract:
<p>Controlling electrical networks that contain high levels of wind power will be a challenge facing many System Operators in the coming years. The intermittency and uncertainty of the power supplied by wind turbines create difficulties surrounding scheduling of plant, operating reserve and grid integration. The current process for windfarm selection is carried out by an individual stakeholder and lacks the consideration for all other stakeholders involved, which can create problems in the long term when the levels of wind power increase on the network. This paper proposes a collective approach to analysing potential windfarm sites using the key factors which influence the windfarm output and integration into the network. The wind resource and generation outputs are examined using state of the art analysis software to discover and rate the values of the factors which influence these variables. A spreadsheet incorporating these factors is developed and evaluated, which allows s...

Performance Analysis of Batch Reactor Temperature Control Systems
(2011)
Healy, Michael; McGrory, John
Abstract:
<p>The aim of this project was to investigate the performance of a number of key control strategies in the temperature control of batch reactors. A bench scale model was built and a batch production system was then implemented on this model. As there was no a priori knowledge of the system a number of common system identification methods were investigated. The system was controlled using a Mitsubishi FX(2)N Programmable Logic Controller which was interfaced with a PC running ICONICS<em>, </em>a Supervisory Control And Data Acquisition software package. The system identification methods produced two different models for the system and these models were examined against the actual system using Matlab/<em>SIMULINK</em>, a software package used for technical computing. Then a number of tuning rules were investigated and implemented on both models with the results compared and contrasted. The standard Industry criteria were used to compare the performance o...

Simulation of Reverse Flow Heat Recovery for Pharmaceutical Clean Rooms in Colombia
(2011)
Olaya Pineda, Sandra Juliana; McGrory, John
Abstract:
<p>This dissertation examines, analyses, implements, and evaluates an innovative software heat transfer model for predicting air-to-air heat (energy) recovered in pharmaceutical drying clean rooms in Colombia. The approach provides a synergy between Reverse Flow Heat Recovery technology and activities for the consumption of this energy, not solely within the process, but throughout the whole pharmaceutical complex (e.g. warehouse, office and alternative processes). This novel integrated modelling tool developed using off the shelf software application such as MS Excel combined with MS Visual programming to calculate psychometric points, mass and enthalpy balances for analysing the operation of heat recovery systems. This makes the tool inexpensive and immediately useful “as is”. A case study of a drying operation at a pharmaceutical company in Colombia is used to aid in a critical review of the tool from a pragmatic real-world perspective. Results show dryers are potentially l...

MEMS: Mobile Environmental Management System
(2005)
Gardiner, Keith; Rizzini, A; Carswell, James; Bertolotto, Michela
Abstract:
<p>This paper describes a web-based and Mobile Environmental Management System (MEMS) prototype specifically tailored to perform context-aware queries and updating of spatial datasets. Spatially enabled computing can provide situation aware assistance to both web-based and mobile users by presenting the right information at the right time, place, and situation using context-associated knowledge. Contextassociated knowledge is assembled by combining knowledge gained about information accessed in the past with the activities planned by the user, together with other situation dependencies (e.g. location) of these activities. The MEMS datasets are provided by the Canadian Department of Fisheries and Oceans (DFO) and the prototype is customised to the specific needs of the Great Lakes Laboratory for Fisheries and Aquatic Sciences (GLLFAS) Fish Habitat Management Group's requirements for fish species at risk assessment.</p>

Carswell, James; Gardiner, Keith; Neumann, Marco
Abstract:
<p>Advances in spatially enabled semantic computing can provide situation aware assistance for mobile users. This intelligent and context-aware technology presents the right information at the right time, place and situation by exploiting semantically referenced data for knowledge discovery. The system takes advantage of new metadata standards to enable semantic, user, and device adapted transactions on multimedia datasets. Information accessed in the past and the activities planned by the user, the situation dependencies (e.g. location) of these activities are used to infer future information requirements. The focus of this paper describes an application of the above functionalities for performing mobile context-aware queries and updating of a multimedia spatial database of cultural heritage artifacts concerning early 20th century Dublin. It aims to exploit current consumer trends in mobile device usage by opening new markets for the increasing number of visitors to Dublin’s ...

Viewer-based Directional Querying for Mobile Applications
(2003)
Gardiner, Keith; Carswell, James
Abstract:
<p>With the steady and fast advancements in the integration of geographic information systems and mobile location-based services, interest in exploiting this technology for Cultural Heritage (CH) data sharing has become apparent. In this area there has been an increasing need to integrate positional information with non-positional data and add a spatial dimension to the definition of a users “context”. In this paper we describe an implementation of a viewer-based directional query processor that operates on an Oracle Spatial database. The spatial position and orientation are taken from the viewer’s perspective. Using this frame of reference a view-port is defined in real time as the viewer progresses through the space and used as the primary filter to query an R-tree spatial index. Finally, an experimental implementation shows how the query processor performs within a VRML model of Dublin linked to a spatially enabled CH dataset.</p>

Digital Image Similarity for Geo-spatial Knowledge Management
(2002)
Carswell, James
Abstract:
<p>The amount and availability of high-quality geo-spatial image data, such as digital satellite and aerial photographs, is increasing dramatically. Task-based management of such visual information and associated knowledge is a central concern for organisations that rely on digital imagery. We are developing geo-spatial knowledge management techniques that employ case-based reasoning as the core methodology. In order to provide effective retrieval of task-based experiences that center around geo-spatial imagery, we need to forward novel similarity metrics for directly comparing the image components of experience cases. Based on work in geo-spatial image database retrieval, we are building an effective similarity metric for geo-spatial imagery that makes comparisons based on derived image features, their shapes, and the spatial relations between them. This paper gives an overview of the geo-spatial knowledge management context, describes our image similarity metric, and provide...

An Environment for Mobile Context-based Hypermedia Retrieval
(2002)
Carswell, James
Abstract:
<p>This paper proposes a novel solution to querying hyperlinked multimedia cultural heritage datasets based on the user's context. Context in this sense is defined as the user's location in virtual space and the particular mobile device being modeled together with user preferences or profile. The purpose is to automatically push relevant data from the database server to the client based on this comprehensive definition of the user's context. Consideration in regard to which mobile device is currently being modeled is a primary filter for determining what data will be sent and in what format. For example, image data will not be sent to a mobile phone and video will not be sent to a PDA. The CHI (Cultural Heritage Interfaces) project differs from many of the models encountered on the Web in that its primary focus is not the accurate 3D rendering of a street/landscape, but the simulation of such a physical reality to explore the adaptive hypermedia paradigm in the ...

Progressive Transmission of Spatial Data Over the WWW: Challenges
(2001)
Carswell, James
Abstract:
<p>Progressive transmission of raster images over the WWW has been successfully applied to provide users with coarser versions of the data before downloading a complete image. In the vector domain, progressive transmission remains a challenging topic. Increasing the level of detail of a vector dataset is a complex process that does not simply imply adding pixels to it. In this paper we present a survey of existing models for progressive transmission of spatial data and discuss open problems and challenges related to the progressive transmission of geographic maps in vector format. Finally, we propose a model based on a client-server architecture and on the pre-computation of multiple map representations that can be used to transmit geographic maps progressively over the WWW.</p>

<p>In this paper we present the development of a spatial data management system utilizing sketch-based queries for the content-based retrieval of digital images from topographic databases. We discuss our overall strategy and associated algorithmic and implementational aspects, and present the associated database design issues. The query tools devised in this research are employing user-provided sketches of the shape and spatial configuration of the object(s) which should appear in the images to be retrieved. Our strategy is scale-independent. It is inspired by least-squares matching (lsm), and represents an extension of lsm to function with a variety of raster representations. The results are ranked according to statistical scores and the user can subsequently narrow or broaden his/her search according to the previously obtained results and the purpose of the search.</p>

Knowledge Management for Disparate Etruscan Cultural Heritage
(2008)
McAuley, John; Carswell, James
Abstract:
<p>This paper introduces the TARCHNA approach to managing and presenting contextualised heritage content. The system uses the CIDOC CRM ontology to consolidate a virtual repository of geographically disparate heritage databases and present a holistic view of a fragmented heritage. While previous approaches to presenting heritage collections have focused on the browse and search paradigm, the TARCHNA system uses narrative concepts as a means of presenting and re-using contextualised heritage artefacts within a broader cultural setting.</p>

An Open Source Approach to Wireless Positioning Techniques
(2007)
Rooney, Seamus; Gardiner, Keith; Carswell, James
Abstract:
<p>There are several problems encountered when trying to determine the location of a mobile phone, including weather you are in an urban or rural environment. Also, it is well known that different positioning technologies can work better than others depending on the environment they are in. For example, GPS works well in rural areas but not as well in urban areas, GSM positioning accuracy can be acceptable in urban areas with the right triangulation technology, but is less accurate in rural areas. Positioning with other technologies such as WiFi, Bluetooth, and Semacode all have their own advantages and disadvantages also, depending on the overall environment in which they are used. One research task of the ICiNG project is to address these issues and introduce the next logical step for freely available mobile positioning, advancing the pioneering work done by Place Lab at Intel. The EU-FP6 ICiNG project component that initiates this advance is called the ILC (ICiNG Location C...

Abstract:
<p>Spatially enabled computing can provide assistance to both web-based and mobile users by exploiting positional information and associated contextual knowledge. The Mobile Environmental Management System (MEMS) is a proof of concept prototype that has been developed in order to simplify administrative duties of biologists at the Department of Fisheries and Oceans (DFO), Canada. MEMS aims to deliver contextaware functionality aided by visualization, analysis and manipulation of spatial and attribute datasets. The resulting application delivers a set of functions and services that aids the DFO’s biologists in making everyday management decisions</p>

Triangle Grouping and Structure Recovery for 3D Building Modelling and Visualization

Hegarty, Joe; Carswell, James
Abstract:
<p>Location based and spatial technologies research for the web has endless application for mobile/position content delivery (m-commerce or pcommerce). By exploiting the inherent location-based intelligence of the underling spatial component, relevant examples can include geometrically accurate and photo realistic virtual representations for: property assessments; land/marine information systems; routing information; on-line shopping; cultural heritage/tourist information/sites; etc. A major challenge for this technology is its reliance on professional developers when creating the virtual worlds used for web-based navigation of these services. This paper describes SAMATS, a Semi-Automated Modeling And Texturing System, which has the capability of producing geometrically accurate and photorealistic VR building models for web-based p-commerce applications from a set of geo-referenced terrestrial images. This paper describes the second of three main components that comprise the f...

SAMATS: Edge Highlighting and Intersection Rating Explained
(2005)
Hegarty, Joe; Carswell, James
Abstract:
<p>The creation of detailed 3D buildings models, and to a greater extent the creation of entire city models, has become an area of considerable research over the last couple of decades. The accurate modeling of buildings has LBS (Location Based Services) applications in entertainment, planning, tourism and e-commerce to name just a few. Many modeling systems created to date require manual correspondences to be made across the image set in order to determine the models 3D structure. This paper describes SAMATS, a Semi-Automated Modeling And Texturing System, which has the capability of producing geometrically accurate and photorealistic building models without the need for manual correspondences by using a set of geo-referenced terrestrial images. This paper gives an overview of SAMATS’ components, while describing the Edge Highlighting component and the Intersection Rating step from the Edge Recovery component in detail.</p>

Textual Case-based Reasoning for Spam Filtering: a Comparison of Feature-based and Feature-free Approaches
(2006)
Delany, Sarah Jane; Bridge, Derek
Abstract:
<p>Spam filtering is a text classification task to which Case-Based Reasoning (CBR) has been successfully applied. We describe the ECUE system, which classifies emails using a feature-based form of textual CBR. Then, we describe an alternative way to compute the distances between cases in a feature-free fashion, using a distance measure based on text compression. This distance measure has the advantages of having no set-up costs and being resilient to concept drift. We report an empirical comparison, which shows the feature-free approach to be more accurate than the feature-based system. These results are fairly robust over different compression algorithms in that we find that the accuracy when using a Lempel-Ziv compressor (GZip) is approximately the same as when using a statistical compressor (PPM). We note, however, that the feature-free systems take much longer to classify emails than the feature-based system. Improvements in the classification time of both kinds of system...

A Case-Based Technique for Tracking Concept Drift in Spam Filtering
(2005)

Abstract:
<p>Spam filtering is a particularly challenging machine learning task as the data distribution and concept being learned changes over time. It exhibits a particularly awkward form of concept drift as the change is driven by spammers wishing to circumvent spam filters. In this paper we show that lazy learning techniques are appropriate for such dynamically changing contexts. We present a case-based system for spam filtering that can learn dynamically. We evaluate its performance as the case-base is updated with new cases. We also explore the benefit of periodically redoing the feature selection process to bring new features into play. Our evaluation shows that these two levels of model update are effective in tracking concept drift</p>
