House price increases have been steady over much of the last 40 years, but there have been occasional declines, most notably in the recent housing bust that started around 2007, on the heels of the preceding housing bubble. We introduce a novel growth model that is motivated by time-warping models in functional data analysis and includes a non-monotone time warping component that allows the inc...

This project is a combined analytical and experimental activity to study warping deformation in shafts of non-circular cross section subjected to torsion. This is a supplemental activity for the junior level Mechanics of Materials course. The students see the warping in square sections and their pronounced effects in ductile materials such as aluminum when the stresses exceed the material yield...

In this paper, a handwritten character recognition experiment using a monotonic and continuous twodimensional warping algorithm is reported. This warping algorithm is based on dynamic programming and searches for the optimal pixel-to-pixel mapping between given two images subject to two-dimensional monotonicity and continuity constraints. Experimental comparisons with rigid matching and local p...

Phonemeand formant-specific warping has been shown to decrease formant and cepstral mismatch. These findings have not yet been fully implemented in speech recognition. This paper discusses a few reasons how this can be. A small experimental study is also included where phoneme-independent warping is extended towards phoneme-specific warping. The results of this investigation did not show a sign...

This paper presents a prototype system, which synthesizes entertainment-oriented cartoon face and translates text message to multimedia animation in mobile phone. While a digital real facial photograph and some text are imputed, a piece of exaggerated facial animation with entertainment will be shown in the phone. Three steps are used to get this entertainment effect: first is the illustration ...

The paper presents the development of a new plate/shell stiffener element and the subsequent application in determine frequencies, mode shapes and buckling loads of different stiffened panels. In structural modelling, the plate and the stiffener are treated as separate finite elements where the displacement compatibility transformation takes into account the torsion – flexural coupling in the s...

This note introduces the concept of image warping and treats the special case of Euclidean warping along with a discussion of a Matlab implementation. Secondly an application of image warping is given; namely image mosaicing where images are stitched together – e.g. to form a panoramic view. Effort has been put into making the text as self-containing as possible. However, basic knowledge of lin...

We show that the valley Chern number of low energy band in twisted double bilayer graphene can be tuned through two successive topological transitions, where direct bandgap closes, by changing electric field perpendicular to plane layers. The transitions with changes -3 and +1 explained formation three satellite Dirac points around central cone moir\'e Brillouin zone due presence trigonal warpi...

Essentially, some conditions for the Riemannian factor and the warping function of a standard static space-time are obtained in order to guarantee that no nontrivial warping function on the Riemannian factor can make the standard static space-time Einstein.
