field experiments were conducted on an existing subsurface drainage system in roodasht region of esfahan, ian, to test the performance of drain spacing equations for transient flow. the water table profiles recorded from a series of observation wells indicated an essentially flat water surface. the effective hydraulic conductivity and the degree of anisotropy were calculated as 19.2 cm h-1 and ...

Tobacco consumption—most notably smokeless tobacco use—has become one of the fastest growing detrimental health habits in North America. Adolescents still perceive ST as a safe alternative to cigarettes. This paper provides state-specific information about the prevalence of ST use in the United States. A review of the literature reveals that the groups at highest risk are white youth and young ...

The transportation problem is one of the most popular problems in linear programming. Over the course of time a multitude of exact solution methods and heuristics have been proposed. Due to substantial progress of exact solvers since the mid of the last century, the interest in heuristics for the transportation problem over the last few decades has been reduced to their potential as starting me...

Heavily boron-doped, diamond films can become superconducting with critical temperatures Tc well above 4 K. Here we first measure the reflectivity of such a film down to 5 cm(-1), by also using coherent synchrotron radiation. We thus determine the optical gap 2Delta, the field penetration depth lambda, the range of action of the Ferrell-Glover-Tinkham sum rule, and the electron-phonon spectral ...

SIR The article by Chaturvedi and McKeigue' fails to mention the danger of relying on the 1991 UK census as an accurate estimate of ethnic minority populations. Both Ballard and Kalra,2 in their discussion of the census nationally, and Glover,3 in his figures for the London areas of Camberwell and Hammersmith, point out the huge underrepresentation of black Caribbean men aged 25 to 44. Both rep...

On February 15, 2015, Dan Archdeacon passed away at his home in Burlington, Vermont, after a short battle with cancer. Dan was born in Dayton, Ohio, on May 11, 1954. He spent his early years in Centerville, Ohio, and went on to earn a B.A. at Earlham College (1975), and a Ph.D. in Mathematics at The Ohio State University (1980). There, under the supervision of his advisor Henry Glover, he wrote...

We consider the factorization of an all-pass matrix function E(s) using proper stable minimum-phase factors. State-space formulae for the stable minimum-phase factors of E(s) are derived (when they exist), as well as state-space formulae for the Wiener-Hopf factors. This is achieved using the state-space characterization of allpass matrix functions given by Glover (1984) in conjunction with the...

In this paper, we present a variant of local search, namely the Life Span Method (LSM), for generic combinatorial optimization problems. The LSM can be seen as a variation of tabu search introduced by Glover [18, 19]. We outline applications of the LSM to several combinatorial optimization problems such as the maximum stable set problem, the traveling salesman problem, the quadratic assignment ...
