Computer-Aided Analysis of Nailfold Capillaroscopy Images

Nailfold capillaroscopy (NC) is a non-invasive imaging technique employed to assess the condition of blood capillaries in the nailfold, and is routinely used for the detection of scleroderma spectral disorders, Raynaud’s phenomenon and other connective tissue diseases. In this chapter, we present computer-aided approaches for capillary inspection, in particular focussing on the tasks of image e...

Moving Load Analysis of Submerged Floating Tunnels

The concept of floating submerged tunnels becomes increasingly attractive idea to cross the straits. The structural solution in these bridges includes buoyancy force on tunnel body plus tension in mooring tethers. This paper investigates the effect of submergence on the dynamic response of submerged floating tunnels due to moving load. The inertial effect of the fluid on the submerged structure...

The union of moving polygonal pseudodiscs - Combinatorial bounds and applications

Let P be a set of polygonal pseudodiscs in the plane with n edges in total translating with xed velocities in xed directions. We prove that the maximumnumber of combinatorial changes in the union of P is (n (n)). In general, if the pseudodiscs move along curved trajectories, then the maximum number of changes in the union is (n s+2(n)), where s is the maximum number of times any triple of polyg...

Object-oriented analysis-synthesis coding of moving images

An object-oriented analysis-synthesis coder is presented which encodes objects instead of blocks of N x N picture elements. The objects are described by three parameter sets defining the motion, shape and colour of an object. The parameter sets are obtained by image analysis based on source models of either moving 2D-objects or moving 3D-objects. Known coding techniques are used to encode the p...
