In this paper, the necessary in-cylinder conditions for the transition from spark ignion (SI) to homogeneous charge compression ignition (HCCI) are analyzed.The hereby important factors for ignition time are investigated analytically.A control oriented combustion model, that is validated by experimental data, is used for sensivity analysis and a Mo
Kasus satelit mengalami anomali seringkali di temukan pada satelit-satelit yang beroperasi pada orbit polar.Namun permasalahan yang muncul adalah kondisi satelit sering berubah-ubah sehingga operator belum bisa mengantisipasi kondisi tersebut.Oleh sebab itu, model deteksi kondisi satelit dapat berperan sebagai early warning operator satelit untuk m
We may soon face biophysical limits to perpetual growth.Energy supplies may tighten and then begin a long slow descent while defensive expenditures rise to address problems caused by past resource consumption.The outcome may be significant changes in daily routines at the individual and community level.It is difficult to know when this Hockey Acces
Vibrational behaviour of symmetric angle-ply layered circular cylindrical shell filled with quiescent fluid is presented.The equations of motion of cylindrical shell in terms of stress and moment resultants are derived from the first order shear deformation theory.Irrotational of inviscid fluid are expressed as the wave equation.These two equations
Recently bent products are widely applied into various structures.Sharp bending Accessoires DIY method in bent products has an advantage of fine appearance.On the other hand, it is newly known that origami forming can be applied to freely manufacturing method as fine appearance based on complex folding lines.Sharp bending and origami forming have a
