We consider situations where rays are reflected according to geometrical optics by a set of Boat Covers unknown obstacles.The aim is to recover information about the obstacles from the travelling-time data of the reflected rays using geometrical methods and observations of singularities.Suppose that, for a disjoint union of finitely many strictly c

Aims The liaison psychiatry team at North Middlesex Hospital (NMH) noticed that many patients on clozapine were missing doses in hospital, risking the need for re-titration and deterioration in mental state.Although clozapine is a widely used medication in psychiatry, non-psychiatric clinicians may not be aware of the importance of compliance.In ad

In order to study the influence of the torsional mode, bending mode and umbrella mode of the wheelsets on the vehicle curvepassingperformance, the vehicle-track system dynamics models were established, in which, the wheelsets structures were considered as rigidbody and flexible body respectively.The curve-passing performance of the vehicle was asse
