The European Space Agency’s Planck satellite, launched on 14 May 2009, is the third-generation space experiment in the field of cosmic microwave background (CMB) research. It will image the anisotropies of the CMB over the whole sky, with unprecedented sensitivity ( ΔT T ∼ 2 × 10−6) and angular resolution (∼5 arcmin). Planck will provide a major source of(More)
This study used a mixed methodology with young offenders attending a Youth Offending Service to identify, with regard to mental health problems, perceptions of level of need, experiences of and views on support and perceptions of barriers in accessing services. Between May and September 2008, 44 young offenders completed a questionnaire about their(More)
A boundary-evaluation algorithm for constructive solid geometry is presented for representations in which the primitives can be bounded by complex surfaces (such as splines) as well as by simpler polynomial surfaces. A fundamental part of the algorithm is the spatial decomposition of each primitive in a way that yields three planar bounded volumes, one(More)
