I briefly review the problems with previous investigations of supersymmetry breaking in string theory 1 at tree-level, at one-loop, and non-perturbatively. A variant of the original non-perturbative scenario is proposed, in which gaugino condensation takes place in two different strongly-interacting hidden-sector gauge groups. In the new scenario it is possible to generate a large hierarchy of ...

Abstract Computational fluid dynamics (CFD) is applied to investigate rotational sloshing waves in a top-submerged-lance (TSL) cylindrical metal bath. The study an extension of recent work the authors, where top injection Ar into metallic bath was examined quasi-2D flat setup, allowing numerical model be extensively validated against experimental data based on x-ray radiography. new analysis ga...

Refactorings are behavior-preserving program transformations that automate design level changes in object-oriented applications. Our previous research established that many schema transformations, design patterns, and hot-spot meta-patterns are automatable. This research evaluates whether refactoring technology can be transferred to the mainstream by restructuring non-trivial C++ applications. ...

The paper reviews six examples of CFD applications, useful for: minerals, power generation and oil & gas industry. The review starts with the multiphase modeling of gas injection into a liquid bath, where the CFD results were validated against experimental data. The example is very useful for metal extraction/refining industry. Simulation of a mineral concentrator bin is presented next, where m...

This paper discusses the relationship between education and crime from an economic perspective, developing a human capital-based model that sheds light on key ways in which early childhood programs and policies that encourage schooling may affect both juvenile and adult crime. The paper first discusses evidence on the effects of educational attainment, school quality, and school enrollment on c...
