Blending arts and sciences: gimmick or necessity?

The shortage of degree qualified engineers in the UK is well documented. On the other hand the surplus of art and design graduates is growing. Whilst acknowledging the shortage in engineering graduates, there is also the need to recognise the breadth and increased skill level that engineering graduates require. Is it therefore possible to convert some of the excess graduates in art and design to careers in design and development engineering? The success of many engineering businesses depends not only on technical excellence but also on understanding of the market needs and the speed of response to this demand. To make this task even harder, businesses are also expected to compete in markets that are open to global competition and are also faced with much more sophisticated consumers. Businesses that are engaged in the manufacture of goods now require a new breed of engineer. These are not only technically competent individuals, but also possess what is known as “soft” or “creative” skills traditionally found in graduates of art and design disciplines. This paper details an innovative curriculum model offered at postgraduate level to address the 21 st century needs of engineering businesses. The paper also details rigorous recruitment tools developed and used for selecting students exclusively from the art and design discipline

Product design as a vehicle to integrate arts and sciences in design education

In many parts of the world, Higher Education has often considered arts and sciences as an odd combination and many institutions have avoided this particular mix. Historically, this has been the accepted view; however, this view is changing. This paper provides a detailed account of curriculum development and strategies for enabling arts and science disciplines to blend in an effective way. It shows how strong alliances can be built in line with industry and general design practice expectations through “Live Projects”, that is projects sponsored by industry or other clients. The case studies provided in the paper are based on work conducted in the Product Design and Engineering Department at Middlesex University. The paper further demonstrates the importance of industry involvement, and how industrial collaborations can be managed to ensure that the academic provision is both relevant to the sector as well as responding to the needs of students. The paper was presented at the International Association of Societies of Design Research (IASDR07), held at the Hong Kong Polytechnic University. The papers for the conference were reviewed in a double blind review process, and the conference was attended by an audience of over 400 delegates, focusing on emerging trends in design researc

Revisiting revisitation in computer interaction: organic bookmark management.

According to Milic-Frayling et al. (2004), there are two general ways of user browsing i.e. search (finding a website where the user has never visited before) and revisitation (returning to a website where the user has visited in the past). The issue of search is relevant to search engine technology, whilst revisitation concerns web usage and browser history mechanisms. The support for revisitation is normally through a set of functional built-in icons e.g. History, Back, Forward and Bookmarks. Nevertheless, for returning web users, they normally find it is easier and faster to re-launch an online search again, rather than spending time to find a particular web site from their personal bookmark and history records. Tauscher and Greenberg (1997) showed that revisiting web pages forms up to 58% of the recurrence rate of web browsing. Cockburn and McKenzie (2001) also stated that 81% of web pages have been previously visited by the user. According to Obendorf et al. (2007), revisitation can be divided into four classifications based on time: short-term (72.6% revisits within an hour), medium-term (12% revisits within a day and 7.8% revisits within a week), and long-term (7.6% revisits longer than a week)

Empirical measurements of small unmanned aerial vehicle co-axial rotor systems

Small unmanned aerial vehicles (SUAV) are beginning to dominate the area of intelligence, surveillance, target acquisition and reconnaissance (ISTAR) in forward operating battlefield scenarios. Of particular interest are vertical take-off and landing (VTOL) variants. Within this category co-axial rotor designs have been adopted due to their inherent advantages of size and power to weight ratio. The inter-rotor spacing attribute of a co-axial rotor system appears to offer insight into the optimum design characteristic. The H/D ratio has been cited as a significant factor in many research papers, but to date has lacked an empirical value or an optimal dimensionless condition. In this paper the H/D ratio of a SUAV has been explored thoroughly, reviewing the performance of these systems at incremental stages, the findings from this study have shown that a range of H/D ratios in the region of (0.41-0.65) is advantageous in the performance of SUAV systems. This finding lends itself to the theory of inter-rotor spacing as a non-dimensionally similar figure, which cannot be applied across a spectrum of systems; this could be attributed to the viscous losses of flight at low Reynolds Numbers (< 50,000

Muon capture in the front end of the IDS neutrino factory

We discuss the design of the muon capture front end of the neutrino factory International Design Study. In the front end, a proton bunch on a target creates secondary pions that drift into a capture transport channel, decaying into muons. A sequence of rf cavities forms the resulting muon beams into strings of bunches of differing energies, aligns the bunches to (nearly) equal central energies, and initiates ionization cooling. The muons are then accelerated to high energy where their decays provide neutrino beams. For the International Design Study (IDS), a baseline design must be developed and optimized for an engineering and cost study. We present a baseline design that can be used to establish the scope of a future neutrino Factory facility.Comment: 3 pp. 1st International Particle Accelerator Conference: IPAC'10, 23-28 May 2010: Kyoto, Japa

Intra-specific variation in leaf attributes of four savanna tree species across a rainfall gradient in tropical Australia

Leaf attributes of four savanna tree species were measured along a rainfall gradient (1650-950 mm per annum) in the Australian monsoon tropics. As the mean annual rainfall decreased, leaf thickness increased for three of these four species. However, a corresponding decrease in leaf density for two species meant that leaf mass per area increased significantly only for one species. Physiological measurements were made during both the wet and dry seasons on comparable stands of vegetation near the extremes and middle of this gradient. Assimilation per unit mass was similar at all three sites but assimilation per leaf area was higher at the drier sites because leaves were thicker with higher mass per area. These results probably reflect reduced tree density and leaf area index at the drier sites, which offsets the lower rainfall, potentially allowing similar rates of assimilation per unit carbohydrate invested in leaves. © CSIRO 2005
