The Role of the Manufacturer in Air Transportation Planning

The role of the aircraft manufacturer in the airline industry is considered. The process is illustrated by using a fictitious airline as an example--that is, a case study approach with Mid-Coast Airways serving as the example. Both in slide form and with supporting papers, a brief history of the airline, a description of its route structure and a forecast based on econometric analysis are presented. Once the forecast rationale is explained, information outlines the requirements for additional aircraft and the application of new aircraft across the system using alternative fleet plan options. The fleet plan is translated into financial summaries which indicate the relative merit of alternative aircraft types or operating plans

Changing academic practice at a UK research-intensive university through supporting the scholarship of teaching and learning (SoTL)

Over the past decade, there have been many changes in Higher Education in the UK. Alongside increased student participation and widening access, the government has called for universities to professionally develop teachers in Higher Education and recognise the role of learning and teaching in the sector. The University of Glasgow has responded to this changing agenda in a number of ways. At the institutional level, the University launched its first comprehensive Learning and Teaching Strategy in 2006. At the same time it also appointed Associate Deans of Learning and Teaching in each Faculty. Another initiative has been the introduction of a ‘teaching’ career track, through the establishment of a new category of academic staff, the University Teacher, with promotion procedures supporting career development up to Professorial level. Rather than engaging in research (one of the main academic roles of the lecturer, associate professor in US terms), University Teachers must engage in scholarship, in addition to their teaching and administration duties. The establishment of a Learning and Teaching Centre responsible for supporting the University in the implementation of its Learning and Teaching Strategy has also consolidated and initiated a number of activities that all aim to enhance the Scholarship of Teaching and Learning at Glasgow. These initiatives have wrought changes at an institutional level and are contributing to changing academic practice. In particular, the term ‘Scholarship of Teaching and Learning’, once unheard of at the institution is increasingly being recognised as a valid form of academic activity and increasing numbers of academic staff are engaging in it. This paper will outline some of these changes and offer reflections on their impact on SoTL and academic practice

Holistic finite differences accurately model the dynamics of the Kuramoto-Sivashinsky equation

We analyse the nonlinear Kuramoto-Sivashinsky equation to develop an accurate finite difference approximation to its dynamics. The analysis is based upon centre manifold theory so we are assured that the finite difference model accurately models the dynamics and may be constructed systematically. The theory is applied after dividing the physical domain into small elements by introducing insulating internal boundaries which are later removed. The Kuramoto-Sivashinsky equation is used as an example to show how holistic finite differences may be applied to fourth order, nonlinear, spatio-temporal dynamical systems. This novel centre manifold approach is holistic in the sense that it treats the dynamical equations as a whole, not just as the sum of separate terms

Simulation of the small punch creep test with consideration of variation of material properties

A new finite element model of the small punch creep test is described. The material constitutive relationship for creep considered is a simple Norton power law: in this study the exponent in the power law is varied for each element to simulate the random behaviour of creep. The influence of this random variation, and the effect of the friction factor between the punch and specimen, on the deformation and stress field has been investigated

On the Cost of Negation for Dynamic Pruning

Negated query terms allow documents containing such terms to be filtered out of a search results list, supporting disambiguation. In this work, the effect of negation on the efficiency of disjunctive, top-k retrieval is examined. First, we show how negation can be integrated efficiently into two popular dynamic pruning algorithms. Then, we explore the efficiency of our approach, and show that while often efficient, negation can negatively impact the dynamic pruning effectiveness for certain queries
