Solar thermal power systems point-focusing thermal and electric applications projects. Volume 1: Executive summary

The activities of the Point-Focusing Thermal and Electric Applications (PETEA) project for the fiscal year 1979 are summarized. The main thrust of the PFTEA Project, the small community solar thermal power experiment, was completed. Concept definition studies included a small central receiver approach, a point-focusing distributed receiver system with central power generation, and a point-focusing distributed receiver concept with distributed power generation. The first experiment in the Isolated Application Series was initiated. Planning for the third engineering experiment series, which addresses the industrial market sector, was also initiated. In addition to the experiment-related activities, several contracts to industry were let and studies were conducted to explore the market potential for point-focusing distributed receiver (PFDR) systems. System analysis studies were completed that looked at PFDR technology relative to other small power system technology candidates for the utility market sector

Quantum Arthur-Merlin Games

This paper studies quantum Arthur-Merlin games, which are Arthur-Merlin games in which Arthur and Merlin can perform quantum computations and Merlin can send Arthur quantum information. As in the classical case, messages from Arthur to Merlin are restricted to be strings of uniformly generated random bits. It is proved that for one-message quantum Arthur-Merlin games, which correspond to the complexity class QMA, completeness and soundness errors can be reduced exponentially without increasing the length of Merlin's message. Previous constructions for reducing error required a polynomial increase in the length of Merlin's message. Applications of this fact include a proof that logarithmic length quantum certificates yield no increase in power over BQP and a simple proof that QMA is contained in PP. Other facts that are proved include the equivalence of three (or more) message quantum Arthur-Merlin games with ordinary quantum interactive proof systems and some basic properties concerning two-message quantum Arthur-Merlin games.Comment: 22 page

NHBC Foundation: improving recruitment of young people into home building : a literature review

This literature review was undertaken to support research into young people's attitudes to careers in house building. The review is based on database searches supplemented by the evidence gathered during stakeholder interviews and through requests made to the wider careers and home building sectors. In order to fully answer the main research questions, the literature mapping the barriers faced by young people to working within the sector was explored. Based on the review a set of criteria for analysing and categorising industry sector initiatives will also be developed. The criteria will be presented as a separate compendium of opportunities.National House Builders Council Foundatio

Evaluating the Legacy Careers Project.

The Legacy Careers Project was a five day programme of career enrichment activities for schools in East London. The programme ran from June to December 2013 with students moving from Year 8 to Year 9. It provided information and activities to support students to better understand their future career options. The project takes its inspiration from the Olympic Games and is informed by the opportunities offered by Queen Elizabeth Olympic Park. This paper sets out the findings of an evaluation of the project conducted by the International Centre for Guidance Studies. The evaluation concludes that the project was successful. Evaluators noted the delivery of an effective and coherent career learning programme that aligned well with best practice in the sector. Key indicators of success are as follows: • Students who participated in the programme reported that they enjoyed the experience and found it useful; • A high level of learning could be observed throughout the programme; • Students reported that they had developed their skills and attributes through the programme; • There was evidence of greater purposefulness in thinking about their next career destination; • The programme exceeded the initial target of 200 participants by providing 770 students (year 8, moving to year 9) and an additional 70 team leaders (year 12) with career enrichment activities outside of the classroom; • There was a high level of positive engagement from the schools involved in the programme; and • The programme also provided opportunities for a group of sixth form team leaders. These students also reported improvements in their self-confidence (53%), leadership skills (47%) and other skills and attributes.London Legacy Development Corporatio
