A model for tracking articulated objects is proposed using a novel 2D revolute-prismatic joint. An extension of the RANSAC and MLESAC algorithms incorporating feature weights is used to perform robust tracking. The models are suitable for tracking certain human body structures. Limbs are modelled as constrained planar patches. A patch can rotate about a joint point that is displaced relative to...

Polymer network models construct the constitutive relationships of a broader polymer from behavior single chain (e.g. viscoelastic response to applied forces, electromagnetic fields, etc.). Network have been used for multiscale phenomena in variety contexts such as rubber elasticity, soft multifunctional materials, biological and even curing polymers. For decades, myriad developed with differin...

Abstract We report here the development of a rotating molecular switch based on metal‐catalyzed reversible (de)‐hydrogenation. Under an argon atmosphere, acceptorless dehydrogenation induces from alcohol to ketone, while reversing hydrogen pressure switches back system alcohol. Based tolane scaffold, such (de)‐hydrogenation enables 180° rotation. The absence waste accumulation in relying chemic...

Factor analysis is a popular multivariate analysis method which is used to describe observed variables as linear combinations of hidden factors. In applications one usually needs to rotate the estimated factor loading matrix in order to obtain a more understandable model. In this article, an l1 penalization method is introduced for performing sparse factor analysis in which factor loadings natu...

A lot of plumbings exist in factories and so on. It is difficult for humans to inspect them directly. Therefore, automated inspection by robots is desirable. However, many of existing inspection robots have to rotate the camera because a conventional camera can see only one direction while a piping has a cylindrical geometry. The use of an omni-directional camera is effective for the solution o...
