Abstract The article presents the use of swarming algorithms in selecting heat transfer coefficient, taking into account boundary condition IV types. Numerical calculations were made using proprietary TalyFEM program and classic form algorithms. A function was also used for calculations, which, during calculation, determined error approximate solution minimalised a pair individually employed al...

BACKGROUND Childhood asthma is generally believed to be a disorder with a good prognosis. However, some asthmatics develop irreversible airway obstruction, probably as a result of airway remodelling. METHODS After 21-33 years, 228 adults (aged 13-44 years at baseline) with a history of asthma were re-examined to assess risk factors for the development of irreversible airway obstruction (IAO, ...

Modelling fluid flows past a body is a general problem in science and engineering. Historical sphere drag and heat transfer data are critically examined. The appropriate drag coefficient is proposed to replace the inertia type definition proposed by Newton. It is found that the appropriate drag coefficient is a desirable dimensionless parameter to describe fluid flow physical behavior so that f...
