To think quantitatively about comovement, we specify the model of Section I. We use a CES production function for one final good. 42 Thus, we can solve the structure of this economy in closed form, and quantify its comovement. Our model differs in a series of small ways from 43 Its main virtue is that it is solvable in closed form, so that the mechanisms are fairly transparent.

When the user is free to write anything, like handwriting, drawings, or gestures, techniques are required to distinguish between modes. Mode detection, preceding recognition, can be an important aid in applications that invite natural pen input. In this paper, a large amount of data, acquired in different contexts, is used to assess eight features on their suitability for mode detection. Six gl...

A new formulation of energy minimising splines, based on Non-Uniform Rational B-Spline (NURBS) curves, is presented. The existing snake models do not facilitate the local control of their shapes without increasing the number of control points. The introduction of NURBS renders more flexibility into the snake model due to the weighting parameters that are made to adapt according to the curvature...

The loss of flexibility in a spinal curvature defines it as a structural spinal deformity; a curvature sufficiently mobile to resolve with a change in posture is a non-structural or 'functional' scoliosis which is within the normal limits of movement for a human spine. It, therefore, seems logical that exercise-based therapies designed to improve and/or maintain flexibility and range of motion ...

Sauropods are often imagined to have held their heads high atop necks that ascended in a sweeping curve that was formed either intrinsically because of the shape of their vertebrae, or behaviorally by lifting the head, or both. Their necks are also popularly depicted in life with poses suggesting avian flexibility. The grounds for such interpretations are examined in terms of vertebral osteolog...

Recently, animations with deforming objects have been frequently used in various computer graphics applications. Morphing of objects is one of the techniques which realize shape transformation between two or more existing objects. In this paper, we present a novel morphing approach for 3D triangular meshes with the same topology. The basic idea of our method is to interpolate the mean curvature...

Music is highly relational and in this manner shares much in common with other characteristically human behavior. While this may suggest that the processes used in music perception could be domain general, the nature and flexibility of these representations remain less understood. If the underlying representations and manipulations required for perceiving music overlap with those in other cogni...

Methods for damage localization, based on modal parameters, are validated by means of numerical examples and experiments. In this paper, different load and damage cases are simulated with a Finite-Element model of a prestressed reinforced concrete bridge. Taking nonlinear material behaviour into account, realistic crack propagations and decrease of stiffness can be detected. The damage is local...

One important component underlying lexical extension, categorization and induction tasks is the ability to flexibly attend to different dimensions in a variety of contexts. Flexible behaviors are well documented in young children, and it is often argued that (a) associations and associative mechanisms are too unconstrained to allow for such flexibility and (b) flexibility requires conceptual kn...
