The set of min-max functions F : R n ! R n is the least set containing coordinate substitutions and translations and closed under pointwise max, min, and function composition. The Duality Conjecture asserts that the trajectories of a min-max function, considered as a dynamical system, have a linear growth rate (cycle time) and shows how this can be calculated through a representation of F as an...

Several alternate linear prediction parametric representations are experimentally compared as to their vowel recognition performance. The speech data used for this purpose consist of 900 utterances of 10 different vowels spoken by 3 speakers in a/b/-vowel-/b/context. The cepstral coefficients representation is found to be the best linear prediction parametric representation. ~chantillons de 10 ...

The problem of the non-causal inversion of linear multivariable discrete-time systems is analyzed in the geometric approach framework and is solved through the computation of convolution pro#les which guarantee perfect tracking under the assumption of in#nite-length preaction and postaction time intervals. It is shown how the shape of the convolution pro#les is related to both the relative degr...

this paper estimates the determinants of inflation in iran using a linear and non- linear regression model over the period 1959-2008. in the model specification, the conventional variables (liquidity, production and exchange rate) as well as positive and negative oil revenue shocks, monetary disequilibrium, and demand gap are considered. the results show that nonlinear time series regression mo...

BACKGROUND In ageing populations, informal care holds great potential to limit rising health care expenditure. The majority of informal care is delivered by spouses. The loss of informal care due to the death of the spouse could therefore increase expenditure levels for formal care. OBJECTIVE To investigate the impact of the death of the spouse on health care expenditure by older people throu...

The aims of the present study were to examine possible effects of age and sex on energy expenditure independent of differences in body composition, and to develop prediction equations for individual estimation of energy expenditure. The study is based on 235 female and 78 male subjects ranging in age from 15 to 64 y and with body mass indexes (in kg/rn2) ranging from 16.9 to 50.5. Basal metabol...

Weight loss/weight control is a major concern in prevention of cardiovascular disease and the realm of health promotion. The primary aim of this study was to investigate the effect of neuromuscular electrical stimulation (NMES) at different intensities on energy expenditure (oxygen and calories) in healthy adults. The secondary aim was to develop a generalized linear regression (GEE) model to p...

The paper considers the impact of healthcare systems and how they are financed on the life expectancies (LEs) of women and men in 19 OECD countries during the period 1990-2005 using OECD Health Data 2009. There is a gap in life expectancy (LE) between men and women, with women living longer than men, and most studies point to socio-economic variables and lifestyle and health-related behaviors. ...
