Book 2013society is complex; every government is complex. Yet, well-intentioned international development aid, born in an era of infrastructure projects, continues to apply simplistic technical solutions to these wickedly complex development problems. It‘s an outside-in approach that rarely succeeds, even by误传 发表于 2025-3-27 01:30:53
Jim Armstrongoquium on fatigue, which was held at the Royal Institute of Technology (Kung!. Tekniska Hogskolan) in Stock holm, May 25-27, 1955. 35 lectures were delivered, principally dealing with problems of statistical and basic nature. Among the topics were to be found statis tical theory of fatigue, cumulaAbduct 发表于 2025-3-27 09:10:45
Jim Armstrongrantee the minimizing character of the extremal obtained. Thus the possibility of the occurrence of Jacobi conjugate points on rocket extremals motivates the present study of the simplified case of planar vacuum flight in an inverse square law gravity field under constant thrust.

Jim Armstrong à frontière semi-affines, c‘est-à-dire de frontières ayant en commun en chaque point avec leur hyperplan tangent une sousvariété affine de cet hyperplan..On montre d‘abord la possibilité de transformer tout problème à frontière semi-affine en un problème équivalent à frontière totalement affine.
