Performance Evaluation for a 100 W Stirling Engine

A small 100 W displacer-type Stirling engine, Ecoboy-SCM81 has being developed by a committee of the Japan Society of Mechanical Engineers. The engine contains unique features, including an expansion cylinder which is heated by either combustion gas or direct solar energy. Also, a simple cooling system rejects heat from the working gas. A displacer piston has both heating and cooling inner tube...

ON (q; r; w)-STIRLING NUMBERS OF THE SECOND KIND

In this paper, we introduce a new generalization of the r-Stirling numbers of the second kind based on the q-numbers via an exponential generating function. We investigate their some properties and derive several relations among q-Bernoulli numbers and polynomials, and newly de…ned (q; r; w)Stirling numbers of the second kind. We also obtain q-Bernstein polynomials as a linear combination of (q...

Stirling Distributions and Stirling

The left-truncated generalized Poisson distribution belongs to the family of the modified power series distributions. Using sufficiency and completeness of £ ^ x . (minx , , $ 3 x 0 ) respectively, when the truncation point is known (resp. unknown), the minimum variance unbiased (M.V.U) estimator for certain functions of the parameter $ (resp. 0, r) involved in these distributions can be obtain...

Stirling COGNITIVE

This research began as an examination of the problem solving strategies of individuals who believe they can control reinforcements they recelve (internals) and those who believe that outside forces control reinforcements (externals) under different conditions of skill and chance. This developed into a study of the cognitive functioning of internals and externals in concept formation tasks. Inte...
