Flow separation detector

An arrangement for sensing the fluid separation along a surface which employs a thermally insulating element having a continuous surface blending into and forming a part of the fluid flow surface is described. A sudden decrease in the temperature of the downstream sensor conductor and concomitant increase in the temperature of the upstream sensor conductor is an indication of the separation. When the temperatures are returned to the state achieved during normal flow, the indicator thereby indicates the normal, attached fluid flow. The conductors may be, for example, wires or thin films, and should be within the viscous sub-layer of the expected fluid flow. A single heater and several pairs of sensors and corresponding sensor conductors may be used to detect not only the fluid flow and the separation, but the direction of the fluid flow, over the fluid flow surface

Dobson-stations performance assessment using TOMS data

Examples of comparisons of monthly summaries (based on daily measurements) of some of the regularily operating Dobson stations, with the values deduced from the Total Ozone Mapping Spectrometer (TOMS) overpass are given. Shortcomings in certain Dobson stations are identified, such as: use of an incorrect value for the extraterrestrial constant (HOBART); sudden large volume changes (Brisbane); unusually low Dobson readings (Mauna Loa); and use of inaccurate cloud blue sky charts, causing fictitious differences with direct sun measurements (Toronto)

Academic-Industry Collaboration for Commercial Film and Television Production : an exploration of case studies

Over the past decade, new types of academic-industry collaborations for commercial film and television production have emerged that aim to help the university partner enhance vocational relevance of their programmes and the industry partner to both find and nurture new talent as well as enable more cost-effective means of production. Building on previous work, this paper considers two collaborative models: University as ‘Production Partner’ and University as ‘Service Provider’. It presents an overview of case studies from a range of collaborations worldwide considering how these partnerships were structured, how stakeholder needs were considered, the benefit to students and graduates, and overall project effectiveness. It then looks in detail at the collaboration between the University of York, UK, and Green Screen Productions Ltd. for the creation of the feature film, The Knife That Killed Me (2014), backed by Universal Pictures UK. Findings suggest that both models are viable but that partners, particularly academic, must understand the nature of engagement in terms of how it relates to their institutional objectives to maximise benefit. It is suggested that these types of collaborations can be utilised in any industrial media setting globally so long as there is careful consideration of the needs and expectations of all participants

An Assessment of PIER Electric Grid Research 2003-2014 White Paper

This white paper describes the circumstances in California around the turn of the 21st century that led the California Energy Commission (CEC) to direct additional Public Interest Energy Research funds to address critical electric grid issues, especially those arising from integrating high penetrations of variable renewable generation with the electric grid. It contains an assessment of the beneficial science and technology advances of the resultant portfolio of electric grid research projects administered under the direction of the CEC by a competitively selected contractor, the University of California’s California Institute for Energy and the Environment, from 2003-2014
