BACKGROUND Thong style flip-flops are a popular form of footwear for children. Health professionals relate the wearing of thongs to foot pathology and deformity despite the lack of quantitative evidence to support or refute the benefits or disadvantages of children wearing thongs. The purpose of this study was to compare the effect of thong footwear on children's barefoot three dimensional foot...

This paper presents a machine learning approach for accurate estimation of energy expenditure using a fusion of accelerometer and heart rate sensing. To address short comings in existing off-the-shelf solutions, we designed Jog Falls, an end to end system for weight management in collaboration with physicians in India. This system is meant to enable people to accurately monitor their energy exp...

A popular design style involves tiling a two-dimensional area withcompacted basic cells such that all needed inter cell connections are between pairs of adjacent cells [l,lO]. Furthermore, adjacent cells have the same number of pins on their common boundary and the ith pins of the two cells are to be connected for all i. In the example of Fig. 1 the adjacent cells A and B each have four pins on...

For discrete-time descriptor syslems, various generalized Lyapunov equations were studied in the literature. Howevn these well known generalized Lyapunov equations can be used only under some restrictive assumptions on the plant (as system regularity, or positiveness of a Q matrix, for example). To overcome these limitations, we propose in this paper a new generalized Lyapunov equation for disc...

In this paper we introduce a general framework for compaction on a torus. This problem comes up whenever an array of identical cells has to be compacted. We instantiate our framework with several specific compaction algorithms: one-dimensional compaction without and with automatic jog insertion and two-dimensional com-

By definition, an autonomous function is a differentially algebraic function Jon iw (or on C), every translate J, of which satisfies every algebraic differential equation that J satisfies. We find several equivalent formulations of the property of being autonomous. Our main result is that if Jis differentially algebraic and meromorphic in the full complex plane, and if g is an autonomous entire...
