A new weighting scheme and discriminative approach for information retrieval in static and dynamic document collections (2014)
Conference Proceeding

This paper introduces a new weighting scheme in information retrieval. It also proposes using the document centroid as a threshold for normalizing documents in a document collection. Document centroid normalization helps to achieve more effective inf...

UWB/GNSS-based cooperative positioning method for V2X applications (2014)
Conference Proceeding

Limited availability of GNSS signals in urban canyons is a challenge for the implementation of many positioning-based traffic safety applications, and V2X technology provides an alternative solution to resolve this problem. As a key communication com... Read More about UWB/GNSS-based cooperative positioning method for V2X applications.

Assessing the accuracy of loss estimation methods for supercapacitor energy storage devices operating under constant power cycling (2014)
Conference Proceeding

This paper assesses different energy loss estimation methods using the supercapacitor model parameters extracted from the electrochemical impedance spectroscopy (EIS). Two energy loss estimation methods are applied to two similar supercapacitors from...

Finding information about mental health in microblogging platforms: a case study of depression (2014)
Conference Proceeding

Searching for online health information has been well studied in web search, but social media, such as public microblogging services, are well known for different types of tacit information: personal experience and shared information. Finding useful... Read More about Finding information about mental health in microblogging platforms: a case study of depression.

A user defined taxonomy of factors that divide online information retrieval sessions (2014)
Conference Proceeding

Although research is increasingly interested in session-based retrieval, comparably little work has focused on how best to divide web histories into sessions. Most automated attempts to divide web histories into sessions have focused on dividing web... Read More about A user defined taxonomy of factors that divide online information retrieval sessions.

Predicting unexpected influxes of players in EVE online (2014)
Conference Proceeding

EVE Online is a massively multiplayer online role-playing game (MMORPG) taking place in a large galaxy consisting of about 7 500 star systems. In comparison to many other online role-playing games, the users interact in the same instance of a persist... Read More about Predicting unexpected influxes of players in EVE online.

The Effects of the Planning Horizon on Heathrow TSAT Allocation (2014)
Conference Proceeding

Decidable model-checking for a resource logic with production of resources (2014)
Conference Proceeding

Several logics for expressing coalitional ability under resource bounds have been proposed and studied in the literature. Previous work has shown that if only consumption of resources is considered or the total amount of resources produced or consume...

Review of food toxicological issues associated in rubber products (2014)
Conference Proceeding

Over the centuries, rubber latex gained its popularity in machinery application due to its unique thermal properties, high elasticity and excellent impact resistance. It is widely accepted in food industry as rubber has good resistance to chemicals,... Read More about Review of food toxicological issues associated in rubber products.

Built-in reliability design of a high-frequency SiC MOSFET power module (2014)
Conference Proceeding

A high frequency SiC MOSFET-based three-phase, 2-level power module has been designed, simulated, assembled and tested. The design followed a built-in reliability approach, involving extensive finite-element simulation based analysis of the electro-t... Read More about Built-in reliability design of a high-frequency SiC MOSFET power module.

Programming by Example Using Least General Generalizations (2014)
Conference Proceeding

Recent advances in Programming by Example (PBE) have supported new applications to text editing, but existing approaches are limited to simple text strings. In this paper we address transformations in richly formatted documents, using an approach bas... Read More about Programming by Example Using Least General Generalizations.

Environmental Scanning and Knowledge Representation for the Detection of Organised Crime Threats (2014)
Conference Proceeding

ePOOLICE aims at developing an efficient and effective strategic early warning system that utilises environmental scanning for the early warning and detection of current, emergent and future organised crime threats. Central to this concept is the use... Read More about Environmental Scanning and Knowledge Representation for the Detection of Organised Crime Threats.

Knowledge Management and Human Trafficking: Using Conceptual Knowledge Representation, Text Analytics and Open-Source Data to Combat Organized Crime (2014)
Conference Proceeding

Globalization, the ubiquity of mobile communications and the rise of the web have all expanded the environment in which organized criminal entities are conducting their illicit activities, and as a result the environment that law enforcement agencies...

Some constructions on ?-groupoids (2014)
Conference Proceeding

Weak ω-groupoids are the higher dimensional generalisation of setoids and are an essential ingredient of the construc- tive semantics of Homotopy Type Theory [10]. Following up on our previous formalisation [3] and Brunerie’s notes [5], we present a... Read More about Some constructions on ?-groupoids.

System-wide assessment of intervention strategies for railway infrastructure (2014)
Conference Proceeding

The existing railway infrastructure exhibits faster degradation rates and requires more maintenance effort as a result of increased utilisation. At the same time, due to increased numbers of freight and commuter trains obtaining access to the railway...

Reconstruction and display of a nineteenth century landscape model (2014)
Conference Proceeding

A fuzzy directional distance measure (2014)
Conference Proceeding

The measure of distance between two fuzzy sets is a fundamental tool within fuzzy set theory, however, distance measures currently within the literature use a crisp value to represent the distance between fuzzy sets. A real valued distance measure is... Read More about A fuzzy directional distance measure.

A support vector-based interval type-2 fuzzy system (2014)
Conference Proceeding

In this paper, a new fuzzy regression model that is supported by support vector regression is presented. Type-2 fuzzy systems are able to tackle applications that have significant uncertainty. However general type-2 fuzzy systems are more complex tha... Read More about A support vector-based interval type-2 fuzzy system.

Understanding issues in mathematical problem solving and modeling: lessons from lesson study (2014)
Conference Proceeding

At the heart of our concern, and research, has been to understand how, in classroom learning, students might develop capabilities towards mathematical literacy (Steen, 2001). We have sought to gain insight into how to teach students to be able to app... Read More about Understanding issues in mathematical problem solving and modeling: lessons from lesson study.

Do subject specialists produce more useful feedback than non-specialists when observing mathematics lessons? (2014)
Conference Proceeding

Schools, districts and inspectorates routinely use non-specialists to observe lessons for accountability and professional development purposes. However, there is little empirical research on how well non-specialists observe lessons. We describe two p...
