We present SPOT, an open-source toolbox for the experimental analysis of optimization algorithms. Evolution strategies (ES) have been severely criticized before they started their triumphal procession as optimization algorithms. Schwefel discussed ideas which appeared to be provocative at the first sight. SPOT provides a modern framework to test these ideas. The extreme programming methodology ...

background: historically open surgical drainage has been the treatment of choice for pyogenic liver abscess. the records of 54 patients with pyogenic liver abscess were reviewed to determine whether earlier diagnosis with current imaging tests and definitive treatment with antibiotics and aspiration drainage was an effective alternative to surgery. methods: the clinical features, laboratory tes...

Relationships have been repeatedly identi ed as an important object-oriented modeling construct. Today most emerging modeling standards such as the ODMG object model and UML have some support for relationships. However while dealing with schema evolution, OODB systems have largely ignored the existence of relationships. We are the rst to propose comprehensive support for relationship evolution....

the developing turbulent flow in an open channel is a complex three-dimensional flow influenced by the secondary currents and free surface effects and is, therefore, not amenable to analytical solution. this paper aims to study the impact of three key hydraulic parameters (relative roughness, the froude number and the reynolds number) on the establishment length using computational fluid dynami...

from applied linguistic point of view, the fundamental question facing the language teachers, methodologists and course designers is which procedure is more effective in fl/sl: learning to use or using to learn? definitely, in order to be a competent language user, knowledge of language system is necessary, but it is not sufficient to be a successful language user. that is why there was a gradu...

Our study theorizes and tests why organizations engage in practices of open strategy and the share-price related outcomes associated with these practices. Drawing from literature on information asymmetry, we suggest that organizations that depart from their existing strategy or deviate from industry norms are more likely to open up their strategy in order to escape negative evaluations by analy...
