A progressive curve representation based on reverse subdivision is introduced. Multiresolution structures for common subdivision rules that have both banded reconstruction and decomposition filters are produced. Multiresolution filters are usually applied to the whole curve uniformly, while progressive curves are based on collapse and split operations that can be applied locally on any portion ...

The Utu Uli Hill, located on the northern Futuna Ridge in Lau Basin (Southwestern Pacific Ocean), displays recent volcanism a complex area, possibly boundary of one many intermediate platelets between and Australian plates or result progressive melting dismantling Vitiaz subduction slab. combination bathymetric, magnetic 3D reflection seismic data allows us to recognize describe several types s...

This paper presents the development and experimental validation of a multi-hazard bridge pier concept, i.e., a bridge pier system capable of providing an adequate level of protection against collapse under seismic and blast loading. A multi-column pier-bent with concrete-filled steel tube (CFST) columns is the proposed concept, and the adequacy of this system is experimentally and analytically ...

Abstract The development of fragility functions that express the probability collapse a building as function some ground motion intensity measure is an effective tool to assess seismic vulnerability structures. However, number factors ranging from selection modeling decisions can influence quantification probability. A methodical investigation was carried out examine effects component and in es...

Kienböck’s disease or lunatomalacia is an aseptic osteonecrosis of the lunate bone initiating a progressive collapse of the lunate bone, followed by total carpal collapse. The first description was made one hundred years ago (107). Thus far, its exact cause and natural history remain unknown (44). Several extrinsic and intrinsic factors have been investigated as to their role in the aetiology o...

We have studied the correlation between the prevention of progressive collapse and the ratio of the intact articular surface of the femoral head, after transtrochanteric rotational osteotomy for osteonecrosis. We used probit analysis on 125 hips in order to assess the ratio necessary to prevent progressive radiological collapse over a ten-year period. The results show that a minimum postoperati...
