Broadband wireless access in an energy efficient environment
Get PDFWireless access into and out of buildings is a fundamental requirement of current and future successful handheld device usage. A number of factors, guided by energy efficiency, can negatively influence the successful propagation of such wireless signals through the building envelope.This work examines commonly used building materials in terms of their attenuation on wireless frequencies from 800-6000MHz and concludes that the external doors are the final remaining wireless openin

An Empirical Analysis Of The Change In The Provision For Credit Losses On Trade Receivables From An Earnings Management Perspective
Get PDFOn the Central Coefficients of Riordan Matrices
Get PDFWe use the Lagrange-Bürmann inversion theorem to characterize the generating function of the central coefficients of the elements of the Riordan group of matrices. We apply this result to calculate the generating function of the central elements of a number of explicit Riordan arrays, defined by rational expressions, and in two cases we use the generating functions thus found to calculate the Hankel transforms of the central elements, which are themselves expressible as combinatorial polynomials. We finally look at two cases of Riordan arrays defined by non-rational expressions. The last example uses our methods to calculate the generating function of
A Framework for Sustainable, Competitive Advantage for the Irish Pharmaceutical Industry
Get PDFThis inductive study seeks to construct a practical strategic framework tailored for use by the Irish pharmaceutical industry to improve its competitive advantage in time. Enhancing the effectiveness of sustainable (predictive), competitive advantage requires strategists to chase change rather than simply react to it. Modern business operates in a complex and dynamic environment, human behaviour is irrational. The application of assumptions and cognitive preference for repetition restricts differentiation being achieved, a fundamental aspect of competitive advantage. The framework was devised, firstly, by utilising interdisciplinary academic theories, spanning behavioural science to business management, to identify the factors important to sustaining the competitive advantage of the Irish pharmaceutical industry, then testing the relevance of the same through time, and finally by developing a methodological prototype for use primarily by Irish senior strategists to formulate their management strategy in context and in time
Breathing Space or Hiding Place? Graduate Entrepreneurs’ Perspectives of Entrepreneurship Education in Ireland
Get PDFEntrepreneurship education (EE) has become a panacea for graduate unemployment
despite a lacuna of empirical evidence to demonstrate that it can generate more
entrepreneurial activity (Matlay, 2007; Potter, 2008). This research examines graduate
entrepreneurs’ perspectives of EE at third level in their formation as entrepreneurs.
The South East Enterprise Platform Programme (SEEPP) provides an interesting case
study of graduate entrepreneurship within South East region of Ireland, where
research was conducted amongst 30 graduate entrepreneurs i.e., 15 SEEPP
participants and 15 non-SEEPP entrepreneurs. This research also included the
perspectives of 15 enterprise enablers, namely SEEPP lecturers and enterprise
development agency (EDA) personnel to provide a triangulated perspective of EE at
third level. The graduate entrepreneurs and enterprise enablers acknowledged
initiatives by HEIs to promote entrepreneurship but they believed that EE does not
adequately prepare students for self-employment mainly because: (i) HEIs are focused
on preparing students for employment; (ii) lecturers lack critical enterprise experience;
(iii) the academic nature of EE; and (iv) EE’s ‘one size fits all’ approach fails to recognise
the heterogeneity of learners’ needs. The notion that more EE will lead to greater
numbers of graduate entrepreneurs is unrealistic because graduates’ route to self-
employment is not linear, moreover, there is a paucity of supports for ‘raw graduates’
in their transition to self-employment. Whilst some EDA personnel regarded EE at
third level as a ‘hiding place’, many graduate entrepreneurs believed that HEIs
provided a ‘breathing space’ to develop their business. This research offers a nuanced
understanding of EE at third level and the prevailing economic conditions for graduate
entrepreneurship in Ireland. It contributes to the advancement of knowledge, practice
and policy by proposing a conceptual framework for EE at third level to meet the
diverse needs of graduate entrepreneurs. It concludes with the identification of areas
worthy of further research

Microstructure-sensitive prediction and experimental validation of fretting fatigue
Get PDFThis paper is concerned with the development of a micro-mechanical methodology for prediction of
fretting fatigue crack nucleation life and short crack propagation. The methodology employs critical
accumulated plastic slip as a fatigue indicator parameter for microstructure-sensitive crack nucleation.
Crystal plasticity unit-cell models are employed for calibration of constitutive and crack nucleation
parameters and a crystal plasticity frictional contact model of the fretting test rig is developed to predict
the micro-scale surface fretting damage, crack nucleation and estimated micro-crack propagation. The
methodology is validated against fretting fatigue tests using a fretting bridge arrangement for 316L
stainless steel.
