Proceedings: Industrial problems posed by carcinogens

Ill-Posed and Linear Inverse Problems

In this paper ill-posed linear inverse problems that arises in many applications is considered. The instability of special kind of these problems and it's relation to the kernel, is described. For finding a stable solution to these problems we need some kind of regularization that is presented. The results have been applied for a singular equation.

On Two Problems Posed by Kenneth Stolarsky

Solutions of two slightly more general problems than those posed by Kenneth B. Stolarsky in [10] are presented. The latter deal with a shape preserving approximation, in the uniform norm, of two functions (1/x) log coshx and (1/x) log(sinhx/x), x ≥ 0, by ratios of exponomials. The main mathematical tools employed include Gini means and the Stolarski means.

On Six Problems Posed

Industrial carcinogens: a need for action.

So Oc on Beginning with Percival Pott’s 1775 observation of an excess of scrotal cancer among young chimney sweeps in London, specific agents and processes in the industrial environment are some of the most wellstudied and well-recognized causes of human cancer. Of the 935 agents and exposure circumstances evaluated by the International Agency for Research on Cancer (IARC), over 400 are now lis...

Ill-posed problems in thermomechanics

Several thermomechanical models have been proposed from a heuristic point of view. A mathematical analysis should help to clarify the applicability of these models, among those recent thermal or viscoelastic models. Single-phase-lag and dual-phase-lag heat conduction models can be interpreted as formal expansions of delay equations. The delay equations are shown to be ill-posed, as are the form...
