Approximating Holant problems by winding
We give an FPRAS for Holant problems with parity constraints and
not-all-equal constraints, a generalisation of the problem of counting
sink-free-orientations. The approach combines a sampler for near-assignments of
"windable" functions -- using the cycle-unwinding canonical paths technique of
Jerrum and Sinclair -- with a bound on the weight of near-assignments. The
proof generalises to a larger class of Holant problems; we characterise this
class and show that it cannot be extended by expressibility reductions.
We then ask whether windability is equivalent to expressibility by matchings
circuits (an analogue of matchgates), and give a positive answer for functions
of arity three
UCL (University College London) Libraries Masterplan: Masterplanning Report
BDP were appointed to undertake a Masterplan for the UCL Main Library and the
UCL Science Library and to identify how these buildings could be re-ordered to
significantly improve the quality of the library environment and to facilitate the
delivery of library services.
An initial brief was agreed with UCL’s Estates Management Committee and a
Masterplan Steering Group established including academic representatives,
library staff and design consultants. To inform the development of this brief, UCL
Library Services undertook a number of consultation exercises with users of the
Library; students, academic staff and external users, together with Library staff.
A number of visits to exemplar library buildings in the UK and continental Europe
were also undertaken to inform the development of options for the buildings.
Following the development and review of initial options for both the Main Library
and Science Library, it was agreed a further, hypothetical New Build Central
Library Option should be reviewed, to accommodate a relocated and consolidated
library service encompassing 7 of the 16 existing libraries currently distributed
across the UCL Estate
Inverkip power station
Architectural review of Inverkip Power Station. Inverkip power station is an oil-fired power station located on the eastern shore of the Firth of Clyde on the west coast of Scotland - between Inverkip and Wemyss Bay in Inverclyde. The coastal location meant the station could draw its cooling water from the sea, obviating the need for the large parabolic towers normally associated with such installations. Resultantly, the most imposing feature of the station is its 778 foot (236 m) high chimney - the third tallest chimney in the UK, and Scotland's tallest freestanding structure

Building the foundations of professional expertise: creating a dialectic between work and formal learning
Recent critiques of management and teacher education curricula and teaching pay particular attention to the disconnection between the de-contextualised, formal knowledge and analytical techniques conveyed in university programs and the messy, ill-structured nature of practice. At the same time research into professional expertise suggests that its development requires bringing together different forms of knowledge and the integration of formal and non-formal learning with the development of cognitive flexibility. Such complex learning outcomes are unlikely to be achieved through a 'knowledge transmission' approach to curriculum design. In this article we argue that in many ways current higher education practices create barriers to developing ways of knowing which can underpin the formation of expertise. Using examples from two practice-focused distance learning courses, we explore the role of distance learning in enabling a dialogue between academic and workplace learning and the use of 'practice dialogues' among course participants to enable integration of learning experiences. Finally, we argue that we need to find ways in higher education of enabling students to engage in relevant communities of expertise, rather than drawing them principally into a community of academic discourse which is not well aligned with practice
A colour-based building recognition using support vector machine
Many applications apply the concept of image recognition to help human in recognising objects simply by just using digital images. A content-based building recognition system could solve the problem of using just text as search input. In this paper, a building recognition system using colour histogram is proposed for recognising buildings in Ipoh city, Perak, Malaysia. The colour features of each building image will be extracted. A feature vector combining the mean, standard deviation, variance, skewness and kurtosis of gray level will be formed to represent each building image. These feature values are later used to train the system using supervised learning algorithm, which is Support Vector Machine (SVM). Lastly, the accuracy of the recognition system is evaluated using 10-fold cross validation. The evaluation results show that the building recognition system is well trained and able to effectively recognise the building images with low misclassification rate

Long Term Mitigation Scenarios: Strategic Options for South Africa
The focus of this document is mitigation: if South Africa takes the decision to mitigate, then this document addresses how to determine the options, the emissions reductions achieved by these options, and the attendant costs of each option. How, then, is South Africa to grow and develop in order to reduce poverty, while at the same time retooling its economy in order to reduce its greenhouse gas emissions
