Camera shake during exposure leads to objectionable image blur and ruins many photographs. Conventional blind deconvolution methods typically assume frequency-domain constraints on images, or overly simplified parametric forms for the motion path during camera shake. Real camera motions can follow convoluted paths, and a spatial domain prior can better maintain visually salient image characteri...

We evaluate the shake up process in the K– photoionisation of atomic carbon, i.e. the 2s → 2p and 3s, and 2p → 3p shake up excitations, within the photon energy range 25 to 45 Ry. As in the atomic boron case, the 2s → 3s excitation is still relatively strong and due to configuration interaction effects dominates the 2p subshell excitation to 3p. The conjugate shake up 2s → 2p is 3% near 45 Ry, ...

Introduction Shake flask cultivation is nowadays a routine technique during process development for mammalian cell lines. During shaken culture, changes in agitation velocity, shaking diameter or shake flask size affect the hydrodynamics in the shake flask. This might be reflected in the growth of the cultured cells. Process parameters such as power input, mixing time, fluid velocity etc. have ...

This paper presents an extensive experimental study of a low-cost, high-performance seismic isolator comprising deformable sphere rolling on concrete surfaces. Polyurethane spheres, with and without steel core, flat or spherical plates, are investigated. Lateral cyclic tests under large displacements demonstrated friction coefficient between 3.7% 7.1%. When tested in shake table 1170 ground mot...
