Creating a distributed mobile networking testbed environment - through the Living Labs approach
Get PDFToday, new ways of constructing and delivering
complex wireless and mobile services require more
elaborate and distributed prototyping, testing, and
validation facilities. Testbeds are becoming an important
tool for integrating technology components into the complex
environment of the wireless world and end-users in their
daily life. However technology in itself is no longer valid –
benefits and usefulness for people in their daily life must be
proven before the technology or service can be said to be a
success
Blogs – Collaborative Learning for the Next Generation
Get PDFThis study aims to determine the effectiveness of weblogs as a tool for collaborative learning in an online environment, with a particular focus on technology students. Some of the VLEs currently in use in third-level institutions restrict the way in which students interact with one another and with their tutors. The use of weblogs as a tool for collaborative learning can help to overcome several of the shortcomings of traditional VLEs by providing a dynamic, user-friendly way for students to peer-review one another’s work and to communicate with their tutors and with one another.
An initial pilot study was conducted over a 10-week period. Salmon’s online learning model was used as a theoretical basis for describing how weblogs could be incorporated into the existing learning environment. The first six sessions focused on the technical aspects of blogs (e.g. permalinks, backlinks, RSS feeds and RSS aggregators). The focus on weblog technology and related technologies (e.g. RSS, XML) was felt to be appropriate for the group as part of their Networks course. In the remaining four sessions, students used their blogs to review one another’s class presentations and to share additional information on their own research with the rest of the class.
Preliminary findings show that the use of weblogs in a blended learning environment, in conjunction with classroom teaching and a VLE can enhance the learning experience for both students and tutor. The level of interaction between blogs was high, with students frequently commenting on and linking to one another’s blogs, suggesting that weblogs promote collaborative learning in an online environment
Empirical algebraic modelling of live weight of Irish dairy cows over lactation
Get PDFThe aim of this study is to derive an equation that has the ability to model live weight of Irish dairy cows over lactation. The data set consisted of 6899 cows from 63 herds, of which 428 were from experimental herds and 6471 cows were from commercial herds. An initial examination focussed on time series techniques, as the data are of a time series nature. Splines were also examined to determine the dimensions of a model required to represent the data. As an incomplete gamma function, which was previously used to model milk yield, has been used in other studies to model live weight, various milk yield models were investigated. Finally, live weight changes between two calvings were modelled as a function of age, days in milk and pregnancy. As multicollinearity was evident in this function, the variance inflation factor was examined and principal component analysis was carried out on the variables responsible for multicollinearity. The proposed live weight model has a better fit than previous models, weak multicollinearity and the residuals are homoskedastic, independent and normally distributed. This live weight model therefore provides an acceptable level of accuracy in representing the shape of the live weight curve for Irish dairy cows and can be easily modified for different environmental scenarios
Initial results from an IPv6 Darknet
Get PDFA darknet is an advertised and routed portion of Internet address space that contains no advertised services. Any traffic observed on a darknet is therefore illegitimate and darknets are useful tools for observing the level of background ‘noise’ on a larger network. Darknets have been used in existing IPv4 networks to help to identify malicious traffic, malware trends, or the consequences of misconfiguration. We have created what may be the world’s first IPv6 darknet to help us observe the ‘noise’ present on the IPv6 Internet and to see how this differs from the IPv4 Internet. Initial results suggest that the level of undirected malicious software active on the IPv6 Internet is currently minimal and there is no apparent undirected port-scanning activity. We suspect this is partially a (predicted) consequence of the larger IPv6 address space and also an indication of the immaturity of the IPv6 Internet at the present time

Librarians Outside The Box: Waterford Institute Of Technology's Library based Virtual Learning Environment (VLE) Training & Development Programme
Get PDFThe article fits into the category of Case Study as defined by the Emerald Publishing
Group :
Describes actual interventions or experiences within organisations. May well be
subjective and will not generally report on research.
Purpose
To outline the structure and development of a library based VLE training programme
at WIT and to describe its origins, implementations and long-term goals. To explain
why WIT Libraries was prepared to diversify from its traditional role and to take on
the challenges involved in this project.
Design / Methodology / Approach
Case study report on the VLE training initiative as it has progressed at WIT.
Describes WIT Libraries’ experience as the main instigator of the WebCT training
programme at WIT and questions whether or not this has been an effective medium
for the introduction of WebCT to WIT.
Findings
Concludes by stating that the Library Unit is capable of implementing a varied and
diverse and successful VLE programme. Stresses the importance of the personnel
involved to the success of the project to date.
Research limitations / implications
The project is still at an early stage of development. The study provides a short-term
view of one small academic library service’s experience of implementing a VLE. No
full-scale user survey has been conducted to date.
Practical implications
This account of WIT Libraries experience of working with a VLE is likely to be a
useful source of practical information for libraries in similar positions, of similar scale,
faced with similar challenges.
Originality / value
Offers practical solutions for libraries in similar positions. The successful
diversification of the traditional library role is likely to be of interest to all members of
the library profession.

Formal Concept Analysis for Digital Ecosystem
Get PDFFormal Concept Analysis (FCA) is an effective tool for
data analysis and knowledge discovery. Concept lattice,
which is derived from mathematical order theory and lattice
theory, is the core of FCA. Many research works of various
areas show that concept lattices structures is an effective
platform for data mining, machine learning, information
retrieval, software engineer, etc. This paper offers a brief
overview of FCA and proposes to apply FCA as a tool for
analysis and visualization of data in Digital ecosystem, and
also discusses the applications of data mining for Digital
ecosystem
ANTECEDENTS OF CONSUMER TRUST WITH RUTHLESS BRAND LEADERS
Get PDFResearch suggests that the development of trust between consumer and brand is the crux of relationship strength. This paper presents a conceptual model of trust development in the consumer-company relationship for brands perceived as ruthless, and examines the influencing role of the ruthless organisational leader. It is conceptualised that even when the leader of an organisation holds a ruthless image, that positive relationship strength can be achieved, due to the mediating role of consumer brand trust. In addition, the paper investigates the long-standing theoretical issue of image congruence and seeks to offer insights into how brands with negative associations are not always destined to receive negative consumer responses. They can in fact result in positive relationship strength between consumers and brands
Exploring natural resources for dealing with waste: The Estuarine Research Group at WIT
Get PDFThe Estuarine Research Group (ERG) has a range of scientific expertise from molecular biology and bioremediation to inorganic chemistry and biological separations. Development of this research team was facilitated through funding under the Technological Sector Research Strand III (Core research strengths enhancement 2000-2006) initiative.
Phase I projects of the research team are focused on novel, fundamental investigations into the chemical and biological mechanisms involved in heavy metal sequestration and binding to a range of seaweeds (Phaeophyceae, Rhodophyceae, and Chlorophyceae) commonly found in the South-East of Ireland. Such research, although fundamental in nature, has positive economic implications for society through the potential development of our natural resources as bioremediation products for metal-laden wastewater streams. A number of parallel research strands involving genetic, bioremediation, ecological and chemical studies are currently ongoing in the group. The combined output from these research elements is aimed at gaining a better understanding of the dynamics of metal uptake by seaweed species
