3D Location and Orientation Estimation using Angle of Arrival
(2009)
Ballal, Tarig; Bleakley, Chris J.
3D Location and Orientation Estimation using Angle of Arrival
(2009)
Ballal, Tarig; Bleakley, Chris J.
Abstract:
This paper discusses the problem of joint location and orientation estimation of a receiver using only angle of arrival (AOA) information. Conventional formulations of the problem consist of a number of nonlinear equations where the number of unknowns exceeds the number of equations. However, formulations presented in this paper simplifies the problem in a way that leads of efficient solutions. Two solutions are presented and their performance is compared via simulations using an indoor application as an example. Results emphasize the effectiveness of the the proposed methods.

3D Mapping, Localisation and Object Retrieval using Low Cost Robotic Platforms: A Robotic Search Engine for the Real-World
(2014)
Whelan, Thomas; Kaess, Michael; Finman, R.; Fallon, M.F.; Johannsson, Hordur; Leonard, John J.; McDonald, John
Abstract:
In this paper we present work in progress on the development of a low-cost autonomous robotic platform that integrates multiple state-of-the-art techniques in RGB-D perception to form a system capable of completing a real-world task in an entirely autonomous fashion. The task we set out to complete is determining the location of a preselected object within the physical world. This experiment requires a robotic framework with a number of capabilities including autonomous exploration, dense real-time localisation and mapping, object detection, path planning and motion control.

3D Printing of Microspheres for Tissue Engineering Scaffolds
(2017)
Lohfeld, Stefan; Salash, J. R.; McHugh, Peter E.; Detamore, M.S.
Abstract:
Microspheres have tremendous potential as a scaffold material for tissue engineering applications due to their capability of encapsulation and controlled release of factors that assist tissue regeneration in the desired fashion. Gradient scaffolds consisting of multiple types of microspheres can release different factors at different sites of the scaffold. Current microsphere scaffold production methods, however, cannot address the need for internal architectures to meet specific requirements in different scaffold regions, e.g., for mechanical properties or porosity. We combined 3D printing and microspheres to create scaffolds with defined internal architectures and tailored placing of materials, intended for bone/cartilage interfaces. Poly(lactic-co-glycolic acid) microspheres were mixed with alginate to create a highly viscous suspension, which was manually expressed through a syringe needle to test feasibility. Subsequently, scaffolds were fabricated using a RepRap printer equipp...

3DWiki: The 3D Wiki Engine
(2010)
Cobos, Yolanda; McDaniel, Bill; Decker, Stefan
Abstract:
We demonstrate one of the potential paths of the evolution of wiki engines towards Web 3.0. We introduce 3dWiki - the 3D wiki engine, which was built according to 2-Layer Interface Paradigm (2LIP). It was developed for use by Copernicus, our vision of a 3D encyclopedia. In the demonstration: We give an overview of 2-Layer Interface Paradigm, an attempt to marry advantages of 3D experience with the advantages of narrative structure of hypertext. We describe step by step how to create an article for Copernicus: from creating models for the 3D background, through authoring the content, creating the c-links, to publishing the result in our encyclopedia. We show how to use a physics engine in our wiki.

Localised deflicker of moving images
(2006)
KOKARAM, ANIL CHRISTOPHER; PITIE, FRANCOIS
Abstract:
Brightness fluctuations in sequences are a typical impairment in archive and modern footage. These fluctuations are mainly temporal but they may also present spatial variations across each individual frame. Current deflicker techniques consider that these variations are smooth but this paper shows that the flicker localisation can be very fine in some cases. This paper presents a deflicker algorithm that is able to handle within a same framework both very smooth spatial variations and very localised variations. The core of the method lies in the parametrisation of the flicker model with only one parameter per pixel. The viability of using such a fine parametrisation is made possible by employing a temporal filtering that effectively separates occlusions from the flicker estimation.

Laughter and Topic Changes: Temporal Distribution and Information Flow
(2012)
VOGEL, CARL; CAMPBELL, NICK
Abstract:
Laughter is an important component of social interaction that has attracted interest within conversational analysis. However, it is not universally accepted that laughs have a function in discourse structure. In this study we explore laughter in conversation in relation to topic changes trying to understand whether laughter can be considered as a signal of discourse structure, whether there is a recurrent pattern in laughter distribution with respect to topic changes, and whether laughter has a function in predicting topic changes. In order to answer these general questions, we investigate the laughter-topic change relation from two different points of view (timing and information flow), finding interesting regularities in laughter distributions. Thus, laughter has a function in discourse structure and, although not sufficient to predict a topic change in isolation, it can be an important indicator together with other sources of information.

Epistemic Signals and Emoticons Affect Kudos
(2012)
VOGEL, CARL
Abstract:
Our focus is on the interaction between emoticon use and epistemic hedges in the perception of individual contributions to discourse (and posters of those contributions) as deserving of kudos for their input. The communities with English as a lingua franca that we explore consist of self-motivated contributors to user-fora supported by a major multinational with a software technology company. User categories are determined by a few orthogonal classifications: employees, novice users, and experts; recipients of kudos vs. non-recipients of kudos; etc. We explore the interaction between social signals and signals of certainty in content. Among the effects reported are the negative influence of epistemic hedges used in posting on propensity for others in the community to accord kudos to such postings, but a positive influence of the same in interaction with the use of emoticons.

4pMU4. Novel computer aided design of labial flue pipes
(2010)
Moss, Brian; Lewis, Elfed; Leen, Gabriel; Bremer, Kort; Niven, Andrew
Abstract:
A labial flue pipe is a well known tone generator, which is familiar and easily recognisable as the organ pipes seen in many concert halls and churches. However, the design and understanding of the sounding mechanism of such pipes is fraught with difficulty. Traditionally labial pipes are constructed from age-old lookup tables that are closely guarded intellectual secrets. This paper discusses a novel computer program that facilitates the design and construction of such labial flue pipes. The computer program allows almost all aspects of the labial flue pipes design to be varied, the resultant frequency is generated and in addition the Ising efficiency number is provided. Furthermore, a discussion is included related to the fact that even though an Ising number greater than 3 indicates that a pipe is overblown, the fundamental tone is still predominant. A comparison will also be made between a CFD simulation of the labial flue pipe jet mechanism and smoke trail plots typical of such...

Personalised Learning for Casual Games: The 'Language Trap' Online Language Learning Game
(2010)
WADE, VINCENT PATRICK; PEIRCE, NEIL
Abstract:
The features of video games that contribute to effective learning are drawing increasing attention in the world of technology enhanced learning. To date, game based learning has focussed on the learning benefits provided by the inherent motivation, rich visualizations, and low risk of failure, provided by contemporary educational games. Although these advantages create highly engaging and immersive learning environments, there remain additional techniques that can further aid the learning process. The integration of personalisation into educational games presents unique challenges, the most important being the preservation of the gaming experience. In consideration that a well designed educational game can seamlessly blend learning and gaming content, any adaptation of the learning content will ultimately affect the gaming experience. In effect all educational adaptations must be achieved in a manner that is non-invasive to the game play. In this paper we introduce the `Language Tra...

Multimodal Conformity of Expression between Blog Names and Content
(2013)
VOGEL, CARL
Abstract:
Using a sentiment lexicon for German translated into English, Italian, Spanish and Swedish, Tumblr URL names for blog archives are inspected with regard to the category of the content. Across the five languages, where the content would be of concern to anyone who would be inclined to filter offensive content, the URLs are constructed with negative sentiment expressions more often than positive sentiment expressions. Other relations suggestive of either conformity or opposition in expression between the modalities of blog name and blog content in image in text are not strongly visible in the 1000 URL sample studied.

Below Cross-Layer: An Alternative Approach to Service Discovery for MANETs
(2012)
WEBER, STEFAN
Abstract:
Service discovery protocols for mobile ad hoc networks at- tempt to overcome the inability to locate resources presented by networks in which prior knowledge of node identity and capability is not available. Existing approaches continue to rely on underlying address-based rout- ing protocols in order to communicate with discovered services. These two-tier approaches generate routing overheads which negatively impact on performance and network scalability. As high-powered mobile computing devices with wireless connectivity be- come increasingly ubiquitous, the need for routing protocols which can operate at increased network densities becomes more acute. Cross-layer approaches to service discovery in MANETs have attempted to optimize the discovery process through direct integration with underlying rout- ing protocols, however additional steps are necessary to improve service discovery performance, network scalability and application throughput. This paper describes the Service Discov...

DECIPHERING THE EFFECT OF CURRICULA ON THE PERCEPTION OF THIRD LEVEL ENGINEERING - A COMPARATIVE ANALYSIS
(2012)
KELLY, KEVIN
Abstract:
Recent PISA surveys have shown that Ireland?s relative ranking in Mathematics has fallen sharply, while Finland maintains its posit ion at the top of the international table. Simultaneously, Ireland is experiencing a short age of engineers and falling/static demand for engineering programmes, in common wit h many Western economies, while Finland maintains both a strong public image of the p rofession and a sufficient supply of able students into university. The recent economic woes experienced in Ireland have thrown the diffic ulties in the STEM area into sharp focus, and there is, at least currently, a momentum for change in the education system. With Finland having successfully progressed through a similar crisis in the 1990s, and having transformed its education system, it s eems appropriate to examine what lessons can be learned. The structure of the education system at secondar...

Structural and transport properties of Bi-substituted Co2MnO4
(2009)
ARORA, SUNIL KUMAR; SHVETS, IGOR
Abstract:
We report the structural and transport properties of the Bi-substituted Co2MnO4 multiferroic materials. Samples synthesized using the solid state reaction route with the composition BixCo2?xMnO4 (<0x<0.3) exhibit a single phase behavior with a cubic spinel structure (space group Fd3m). The lattice parameter was found to increase with the Bi substitution. The dc-conductivity studies reveal that all the samples possess a semiconducting behavior. The resistivity was found to decrease with the increase in the Bi substitution. The dc- as well as ac-conductivity data were analyzed in the light of various conduction models. The dc-conductivity data are explained using the variable range hopping model. The ac conductivity calculated from the dielectric data as a function of temperature and frequency demonstrates the cross over from small polaron tunneling to correlated barrier hopping type conduction in these materials.

Using sensor networks for pedestrian detection
(2008)
CAHILL, VINNY
Abstract:
Pedestrian safety is a major concern in road transportation as pedestrian/vehicle accidents account for the second largest cause of traffic-related injuries and fatalities worldwide. Considerable work has examined the use of lidar, radar and computer vision for pedestrian detection but existing solutions are costly and work only if pedestrians are in the vehicle's line-of-sight. In this paper, we present a novel technique based on wireless sensor networks that is cheap and enables pedestrian detection beyond the driver's horizon. The detection system is based on the use of "cat's eyes" augmented with embedded processing and communication capabilities that are able to detect pedestrians and forward this information along the road. We describe how such a system was successfully built with SOL, a high-level programming language for wireless sensor networks. Initial results show that the system obtains detection rates of 100%, false positive rates of 0%, and tha...

Using group communication to support mobile augmented reality applications
(2002)
MEIER, RENE; CAHILL, VINNY
Abstract:
Augmented reality and group communication in wireless ad-hoc networks form relatively new fields of research. When using group communication ordering and timeliness requirements are important. Moreover, when using wireless ad-hoc networks, the possibility of network partition is a serious consideration. In this paper we explore these three issues in the context of using group communication to support mobile augmented reality applications. We describe a policy that enables us to handle partitions and failures, while allowing the members in a partition to make progress, although limited by the application?s consistency requirements. We introduce an approach to determining the message ordering requirements needed to maintain a desired level of consistency and timeliness requirements that should be met in order to have the application state correspond to the sequence of events perceived in the real world.

Filtering and scalability in the ECO distributed event model
(2000)
MEIER, RENE; CAHILL, VINNY; HAAHR, MADS
Abstract:
Event-based communication is useful in many application domains, ranging from small, centralised applications to large, distributed systems. Many different event models have been developed to address the requirements of different application domains. One such model is the ECO model which was designed to support distributed virtual world applications. Like many other event models, ECO has event filtering capabilities meant to improve scalability by decreasing network traffic in a distributed implementation. Our recent work in event-based systems has included building a fully distributed version of the ECO model, including event filtering capabilities. This paper describes the results of our evaluation of filters as a means of achieving increased scalability in the ECO model. The evaluation is empirical and real data gathered from an actual event-based system is used. The findings show filters to be highly valuable in making distributed implementations of the model scale, that multica...

Separation of Distributed Real-Time Embedded Concerns with Theme/UML
(2008)
CLARKE, SIOBHAN; CAHILL, VINNY
Abstract:
Model-driven engineering (MDE) addresses platform complexity issues by abstracting platformindependent models for subsequent transformation to platform-specific models. This facilitates the design of a single system model and the subsequent generation of multiple model transformations targeted towards specific platforms. However, the increasing complexity of distributed real-time embedded (DRE) systems complicates the development of adequate system models by requiring multiple concerns, some of which may be crosscutting, to be modelled. Separation of concerns, a software engineering technique that decomposes systems into distinct features with minimal overlap, can be used to manage complexity. Aspect-oriented software development (AOSD) is an emerging technique to separate crosscutting concerns in software and has been demonstrated to improve modularity and thereby reduce the complexity of software. In this paper we show how Theme/UML, an aspect-oriented design approach, can be used...

6-DOF Multi-session Visual SLAM using Anchor Nodes
(2011)
McDonald, John; Kaess, Michael; Cadena, Cesar; Neira, Jose; Leonard, John J.
Abstract:
This paper describes a system for performing multisession visual mapping in large-scale environments. Multi-session mapping considers the problem of combining the results of multiple Simultaneous Localisation and Mapping (SLAM) missions performed repeatedly over time in the same environment. The goal is to robustly combine multiple maps in a common metrical coordinate system, with consistent estimates of uncertainty. Our work employs incremental Smoothing and Mapping (iSAM) as the underlying SLAM state estimator and uses an improved appearance-based method for detecting loop closures within single mapping sessions and across multiple sessions. To stitch together pose graph maps from multiple visual mapping sessions, we employ spatial separator variables, called anchor nodes, to link together multiple relative pose graphs. We provide experimental results for multi-session visual mapping in the MIT Stata Center, demonstrating key capabilities that will serve as a foundation for future...
