In The Continuum, Hermann Weyl gives new bases to the notions of set and function. With them,he constructs mathematics close to physics and solves the continuum problem. Those newNotes on the First Chapter of The Continuum: Intension, Extension, and Arithm... Philosophia Scientiæ, 13-1 | 200915

It is an open question whether the linear extension complexity of the Cartesian product of two polytopes P,Q is the sum of the extension complexities of P and Q. We give an affirmative answer to this question for the case that one of the two polytopes is a pyramid.

One in two marriages in the United States ends in divorce. Close to 30% of children under 18 live in single-parent households. Disruption of many traditional households raises the question of how divorce affects children’s later outcomes. This paper investigates the impacts of parental divorce on children’s educational and labor market outcomes, and studies the mitigating effects associated wit...

Some generalizations of the classical Hurewicz formula are obtained for extension dimension and C-spaces. A characterization of the class of metrizable spaces which are absolute neighborhood extensors for all metrizable C-spaces is also given.

Wireless telephone speech is usually limited to the 300 − 3400Hz band, which reduces its quality. There is thus a growing demand for wideband speech systems that transmit from 50Hz to 8000 Hz. This paper presents an algorithm to generate wideband speech from narrowband speech using as low as 500 bits/s of side information. The 50 − 300Hz band is predicted from the narrowband signal. A sourceexc...

In this paper we study the asymptotic behavior for the tail probability of the randomly weighted sums and their maximum where the usual assumption of independence of random variable X and indepedence between the variable X and the weighted θ are relaxed. We suppose that, the variable X follows a conditional dependence intoduced by Geluk and Tang [6] and the pair (X, θ) follows a certain depende...

the purpose of the study was to identify and prioritize the educational needs and support needed by agricultural extension agents in isfahan, islamic republic of iran. the target population for the study consisted of s3 agricultural extension agents in isfahan province. census population were used therefore, sampling procedures were not utilized and genera i izability of the results was lim...

In this paper, a new two parameters model is introduced. We called it the inverse flexible Weibull extension (IFW) distribution. Several properties of this distribution have been discussed. The maximum likelihood estimators of the parameters are derived. Two real data sets are analyzed using the new model, which show that the new model fits the data better than some other very well known models.

preprint numerics no. 2/2007 norwegian university of science and technology trondheim, norway The 'pseudo-harmonic' extension is an approximation to the common harmonic extension for extending a function over a domain based on its trace along the boundary of the domain. On a circle the two extension methods produce identical results. We present explicit formulas for the computation of distance ...
