 Japanese term or phrase: 進み演算子 This is a term used in control system theory. See, e.g.: http://www.fitc.pref.fukuoka.jp/kenpo/h8/h8-10.htm Is "advance operator" OK?

 interval operator Explanation:If you go to the URL you provided, you will see that one of the equations above the one with the term in question shows Gp(s) where s is the Laplace Transform operator. But in the equation with your term in it, the author talks about the implications of using digital equipment to take periodic measurements and he says that Gp(s) has a 'zero sequence hold introduced'. The sampling cycle 't' (time) becomes scattered causing the Laplace transform operator to become z^-1 (z to the minus 1). He then refers to z as the term you are inquiring about 'susumi enzanshi'. We all know that enzanshi is 'operator' as found in a mathematical equation so the question becomes, what to call 'susumi' that would make sense in this context. I will make a guess that since we are talking about the introduction of a so-called 'zero sequence hold', it would refer to this sequence or interval. To make sense of it though and come up with an accurate term, I would read as much as I can about the Laplace Transform function and the implications of using digital equipment when taking measurements which involve it. The first link I provide talks about an Inverse Laplace Transform that perhaps is related as it talks about digital versus analog measurements. Good luck! :-)

 Thanks for all the help. I followed your suggestion of checking out other links on Laplace transforms, and turned up the following: http://www.mathworks.com/access/helpdesk/help/toolbox/mpc/poly2tfd.shtml ("... where z is the _forward-shift_ operator.") Only 1 point (ooh I feel mean now...)1 KudoZ points were awarded for this answer
