Multistep simulation for three-dimensional ice accretion on an aircraft wing

A simplified icing model combined with Eulerian two-phase flow theory has been proposed and the method was employed for direct simulation of ice accretion occurred on an aircraft wing. An innovative wall boundary condition treatment has been proposed to properly depict the phenonmenon of droplet impact on the wing surface, resulting in enhanced numerical stability in solution process and better agreement with experimental data. The icing model was derived on the basis of the extended Messinger model, and as well as the assumption that the overflow direction follows the air streamline just above the water film. Several concepts like the critical ice thickness have been presented to facilitate the use of this icing model for predicting three-dimensional ice accretions. Preliminary multistep simulation results for one moderate mixed ice accretion case are compared with available experimental data, together with the corresponding single-step results. Further simulation case studies concerning typical glaze ice of more irregular shape and the effect of simulation step interval to update the geometry and the flowfield will be conduted and detailed results will be presented in the final manuscript</p

Pure and deep-level doped semi-insulating CdTe

Experimental conditions for a growth of near stoichiometric high resistive CdTe single crystals with a minimized concentration of point defects have to be defined. The position of the stoichiometric line in the pressure-temperature (P-T) phase diagram was evaluated from high-temperature in situ galvanomagntic measurements. Calculations based on a model of two major native defects (Cd vacancy and Cd interstitial) show, that a very small variation of Cd pressure P-Cd results in a strong generation of uncompensated native defects. Modelling of room temperature carrier density in dependence of the deep defect density N-DD, P-Cd, and annealing temperature T shows, that the range of optimal P-Cd, at which the high resistivity can be reached, broadens with increasing N-DD or decreasing T. It is shown, that at low T < 450degreesC the deep defect density < 10(15) cm(-3) is sufficient to grow the high resistive CdTe. CdTe doped with Vanadium is used as a model example.</p

Broadway rhythm: the sound of the city

By the time the Golden Age of American Musical Theatre had established itself, it was very definitely something that was located at least romantically in 'Broadway': Broadway the street, a central thoroughfare and a nexus of commerce and entertainment, had grown 'up' Manhattan island; Broadway the theatre industry had grown up (matured) into a globalised commodity and lifestyle market; and Broadway the sound had grown up (developed) into a very recognisable idiom. The notion of Broadway is now loaded with all sorts of signification, and a good degree of that becomes reflected in its main product: Broadway song. This paper will look at the three of these elements (Broadway, Broadway and Broadway) in relation to one another, seeing in the forms, orchestrations, rhythms, cadences and performances of Broadway song both patterns of urban commodification and patterns of aspirational migration. Concentrating on seminal songs such as 'Give My Regards to Broadway' (Cohan, 1904), 'Swanee' (Gershwin / Caesar, 1919) and 'New York, New York' (Bernstein / Comden / Green, 1944), and drawing on theoreticians such as Berman, Bachelard and Deleuze and Guattari, I will discuss Broadway song in terms of the 'sound of the city'.</p

Academic careers: the value of individual mentorship on research career progression

The paper discusses how individual mentoring may impact positively on career pathway development for potential and future clinical academic researchers in nursing and allied health professions.Methods: The paper draws on a number of data sources and methodologies in order to fulfil the aims. Firstly, international literature provides an insight into mentoring processes and impact on career development. This is followed by a review of the mentoring experiences based on a UK study on the professorial populations in nursing and allied health professions. The final section reports on results of interviews with early and advanced researchers on their experiences of mentoring.Results: Individual mentoring is valued highly by health care professionals at all stages of career development. It is considered particularly useful when people are in transition towards a more challenging career role.Individuals in receipt of mentoring both formal and informal, report improved confidence in their cability to achieve their career goals. Mentees report improved levels of competence achieved through knowledge aquisition, networking and ability to probelm solve.Conclusions/Summary: Mentoring is considered an important process for health care professionals at all stages of their career.Opportunities to access and receive mentoring support for health care staff in the UK remain limited and sporadic in nature. There are examples of excellent mentoring schemes in place within some institutons and organisations but a national strategy to support mentoring has yet to be developedKey words: Clinical academic careers, mentoring, nursing, allied health professions</p

Game design for older adults: effects of age-related changes on structural elements of digital games

Recent studies report various positive effects on elderly persons playing digital games. Yet, games are rarely designed with an elderly user group in mind. In this paper, this issue is addressed by providing an overview of common age-related changes followed by a summary of game design considerations for senior audiences. The impact of age on game design is discussed based on an analysis of the most important structural elements of games. The analysis shows that age-related changes in users' cognitive and physical abilities affect the use of games on multiple levels, making the complexity of games and interrelations between different game mechanics a crucial factor when designing for older adults. © 2012 Springer-Verlag Berlin Heidelberg.</p

KINECTWheels: wheelchair-accessible motion-based game interaction

The increasing popularity of full-body motion-based video games creates new challenges for game accessibility research. Many games strongly focus on able-bodied persons and require players to move around freely. To address this problem, we introduce KINECTWheels, a toolkit that facilitates the integration of wheelchair-based game input. Our library can help game designers to integrate wheelchair input at the development stage, and it can be configured to trigger keystroke events to make off-the-shelf PC games wheelchair-accessible.</p

Achieving institutional change for a connected future: engaging all staff in student engagement

This paper presents work at the University of Lincoln to strategically enhance student engagement within colleges and across the wider institution, building on the HEA funded Student as Producer initiative. The initiative stimulates thinking about how institutions can go beyond single projects to achieve organisational and cultural change.</p

Machine fault detection during transient operation using measurement denoising

The paper reports and demonstrates a computationally efficient method for machine fault detection in industrial turbine systems. Empirical mode decomposition (EMD) and Savitzky–Golay smoothing filters are used for signal denoising, with a resulting noise index being developed. By comparing the noise index with a power index (also derived in the paper), obtained from the detection of transients using a spectral analysis of the rate-of-change of unit power, three operational conditions are identifiable viz. normal operation, transient operation and operation when subject to emerging machine faults. The accommodation of transient operational conditions of the unit, so as not to create excessive ‘false alerts’, provides a valuable alternative to more traditional techniques, based on PCA for instance, that can only provide reliable information during steady-state operation. The efficacy of the proposed approaches is demonstrated through the use of experimental trials on sub-15MW gas turbines.</p
