This paper presents a proposed static test and numerical study on the mechanical properties of steel-shell–concrete-structure-immersed tunnel nodes, which is used to investigate seismic performance damage mechanism nodes. The based immersed tube project in deep China channel, nodes representing outermost innermost vertical walls tunnel, i.e., L-shaped T-shaped node specimens, were designed fabr...

The proposed Universal Intelligent Interface (UII) consists in two parts. One is a universal part, another is a problem depended part. UII, modeling user in the Frame Network User Model (FNUM), is designed as a shell system which supports a knowledge base and a number of learning agents. The system treats separately (not necessary independently) various elements of user model within the frames ...

We present a semi-analytical method for computing the electromagnetic field in and around 3D nanoparticles (NP) of complex shape and demonstrate its power via concrete examples of plasmonic NPs that have nonsymmetrical shapes and surface areas with very small radii of curvature. In particular, we show the three axial resonances of a 3D cashew-nut and the broadband response of peanut-shell NPs. ...

l. The mechanical behaviour of crab shell is similar to that of prawn solid cuticle, especially in the occurrence of a low strain discontinuity in their bulk tensile stress-strain curves. 2. Although isolated crab chitin breaks in tension by the progressive failure of individual lamellae and exhibits post-fracture delamination, whole crab cuticle fails in an entirely brittle manner. 3. The mech...

This paper presents the concepts, ideas and techniques behind Case Based Reasoning (CBR) in relation to knowledge extraction techniques for health promotion. The ultimate goal is to develop a help-desk service for advice about preventive measures to be taken concerning concrete occupational injury hazards. CBR has been suggested to be a complimentary method to knowledge extraction in order to t...
