Shaking tables are frequently used to determine the dynamic behavior of structures in laboratory environment. In order obtain realistic results experimental studies, table response and performance should be consistent with desired motion. this multidisciplinary study, an application a new method for determining calibrating mechanical developed bi-axial displacement controlled shake according mo...

Photoionization of an atom by X-rays usually removes an inner shell electron from the atom, leaving behind a perturbed "hollow ion" whose relaxation may take different routes. In light elements, emission of an Auger electron is common. However, the energy and the total number of electrons released from the atom may be modulated by shake-up and shake-off effects. When the inner shell electron le...

Abstract Two full-scale building specimens were tested on the shake-table at EUCENTRE Foundation laboratories in Pavia (Italy), to assess effectiveness of an innovative timber retrofit solution, within a comprehensive research campaign seismic vulnerability existing Dutch unreinforced masonry structures. The buildings represented end-unit two-storey terraced house typical North-Eastern Netherla...

Abstract Recent technological advances have enabled earthquake engineering researchers to develop numerical models of increasing complexity, capable duly reproducing even the smallest structural detail. In case unreinforced masonry (URM) structures, however, because their discrete and heterogeneous nature, computational performance tends decrease exponentially as a function adopted refinement l...

Abstract This work presents the simulations of non-linear dynamic response a three-dimensional finite-discrete element model. The model simulates half-scale masonry building aggregate tested on shake table by other Authors. is made two un-connected units having different heights and slightly wall thicknesses. floors are timber beams boards. modelling approach accounts jointly for in-plane out-o...

BACKGROUND Shake flasks are widely used because of their low price and simple handling. Many researcher are, however, not aware of the physiological consequences of oxygen limitation and substrate overflow metabolism that occur in shake flasks. Availability of a wireless measuring system brings the possibilities for quality control and design of cultivation conditions. RESULTS Here we present...
