The object-oriented model is often motivated by its support for new emerging application areas such as finite element analysis (FEA), computer-aided design or office automation systems. However, our experience when building such a system (FEA) using an object-relational database management system is that an object-oriented model extended with multi-methods is needed. Our application domain also...

With the improvement of aircraft requirements in civil and military fields, are developing towards direction high efficiency multi-mission. Foldable wing with large deformation capability will be able to meet flight performance under different conditions. Based on bionic design concept, a feather-like foldable morphing based multi-link mechanism from characteristics birds was designed. In order...

in very recent papers asmild et al. (2003) and halved et al. (2004) based upon potential improvement efficiency index (bogetoft and hougaard,1999) have suggested an alternative nonparametric frontier approach namely multi-directional inefficiency analysis (mea) to estimate the performance efficiency. mea has many advantages over data envelopment analysis (dea) as the standard nonparametric fron...

This paper presents results of a numerical and laboratory investigation into the mooring line forces and slow drift oscillations of large floating structures in multidirectional waves. A procedure for computing the spectral density of the secondorder forces in random multi-directional waves based on the concept of a bidirectional, bifrequency quadratic transfer function is presented. Laboratory...

Non-trivial deformations result in local contractions and expansions. These naturally capture object scalings but can have a negative side effect, namely making object features disappear or inflate. For this reason we want the deformation fields to have zero acceleration in the direction perpendicular to image features; this guarantees that the features are only ‘transported’. This requirement ...

By elastic mechanics, the deformation of single throttle-slice for shock absorber was analyzed, the formula of its deformation was established. According to the relation of the deformation of multi-throttle-slices with the pressure on each slice, the analytic formula of equivalent thickness of multi-throttle-slices was established. Followed is a practical example for the computation of the equi...

The lagoonal and shallow marine sediments of the Penarth Group in UK span Triassic–Jurassic boundary. These contain several disturbed levels with soft sediment deformations (SSDs), such as synsedimentary faults, injective domes, recumbent folds slumps that are recognised most basins from SW England South Wales to NW Northern Ireland. Field observations, notably close link SSDs active attest an ...

In this paper, we describe a new Telepresence system which enables a user to look around a virtualized real world easily in network environments. The proposed system includes omni-directional video viewers on web browsers and allows the user to look around the omni-directional video contents on the web browsers. The omni-directional video viewer is implemented as an Active-X program so that the...
