DTN: An Architectural Retrospective
(IEEE, 2008)We review the rationale behind the current design of the Delay/Disruption Tolerant Networking (DTN) Architecture and highlight some remaining open issues. Its evolution, from a focus on deep space to a broader class of ... -
Dual-Space Re-ranking Model for Document Retrieval
(2012-02-13)The field of information retrieval still strives to develop models which allow semantic information to be integrated in the ranking process to improve perform- ance in comparison to standard bag-of- words based models. A ... -
Dublin Bus Tracking Service: Design and implementation of a device independent passenger information system
(Trinity College Dublin. Department of Computer Science, 2000-09)Traditionally public transport has been perceived as the less desirable alternative to the car. The environmental argument of using public transport has not led to a significant increase in the usage of public transport. ... -
DublinCity: Annotated LiDAR Point Cloud and its Applications
(2019)Scene understanding of full-scale 3D models of an urban area remains a challenging task. While advanced computer vision techniques offer cost-effective approaches to analyse 3D urban elements, a precise and densely ... -
A Dynamic Approach to Reducing Dialog in On-Line Decision Guides
(Trinity College Dublin, Department of Computer Science, 2000-03)Online decision guides typically ask too many questions of the user, as they make no attempt to focus the questions. We describe some approaches to minimising the questions asked of a user in an online query situation. ... -
Dynamic Charging for Information Services
(Institution of Electrical Engineers, 1997)The last five years has seen an incredibly rapid growth in the number of subscribers to the Internet and in the number of organisations which now consider a presence on the world wide web as vital to their commercial ... -
Dynamic Contextual eLearning - Dynamic Content Discovery, Capture and Learning Object Generation from Open Corpus Sources
(AACE - Association for the Advancement of Computing in Education, 2005) -
Dynamic Contextual Usage Metadata for Learning Resource Reuse in Adaptive Environments
(2011)Drawing on the experiences and context of others who have already used a particular resource can greatly facili- tate that resource?s reuse. Such reuse is essential when the resources in question are digital learning assets, ... -
Dynamic Environment Mapping for Augmented Reality Applications on Mobile Devices
(2018)Augmented Reality is a topic of foremost interest nowadays. Its main goal is to seamlessly blend virtual content in real-world scenes. Due to the lack of computational power in mobile devices, rendering a virtual object ... -
Dynamic Hypertext Generation for Reusing Open Corpus Content
(ACM, 2009)Adaptive hypermedia systems traditionally focus on providing personalised learning services for formal or informal learners. The learning material is typically sourced from a proprietary set of closed corpus content. A ... -
Dynamic Integration of Classifiers for Tracking Concept Drift in Antibiotic Resistance Data
(Trinity College Dublin, Department of Computer Science, 2005-02-17)In the real world concepts are often not stable but change with time. A typical example of this in the medical context is antibiotic resistance, where pathogen sensitivity may change over time as new pathogen strains ... -
Dynamic Integration of Classifiers in the Space of Principal Components
(Trinity College Dublin, Department of Computer Science, 2003)Recent research has shown the integration of multiple classifiers to be one of the most important directions in machine learning and data mining. It was shown that, for an ensemble to be successful, it should consist of ... -
Dynamic Integration of Regression Models
(Trinity College Dublin, Department of Computer Science, 2004-03-26)In this paper we adapt the recently proposed Dynamic Integration ensemble techniques for regression problems and compare their performance to the base models and to the popular ensemble technique of Stacked Regression. We ... -
Dynamic Integration with Random Forests
(Trinity College Dublin, Department of Computer Science, 2006)Random Forests are a successful ensemble prediction technique that combines two sources of randomness to generate base decision trees; bootstrapping instances for each tree and considering a random subset of features ... -
Dynamic optical path allocation in multi-layer traffic engineering
(2007)Hybrid electro-optical architectures have been recently proposed as cost-effective solution to challenge nearfuture traffic demands. We believe that IP routing technology can be closely integrated with optical circuit ... -
A dynamic proxy based architecture to support distributed Java objects in a mobile environment
(Springer Berlin / Heidelberg, 2002)The need to dynamically modify running applications arises in systems that must adapt to changes in their environment, in updating long-running systems that cannot be halted and restarted, and in monitoring and debugging ... -
Dynamic semantics for metaphor
(2001)An intensional logic with dynamic interpretation is presented in order to provide a formal semantics for sense extension, lexical ambiguity and metaphoricity. Intensionality is required in order to provide the right ... -
Dynamic Software Evolution and The K-Component Model
(2001)There are known classes of software systems that can benefit from dynamic software evolution, including 24x7 systems that require on-line upgrades and adaptive systems that need to adapt to frequent changes in their ... -
Dynamically Adjusting Digital Educational Games Towards Learning Objectives
(2010)Personalization techniques offer the possibility to tailor each learner?s experience of a Digital Educational Game (DEG) to their specific needs. Such personalizations can adapt the challenge and difficulty of the DEG ...
