Masonry Vaults: Cross and Cloister Vaults,ly unpredictable, as is the expected time of stability of any existing structure and taxonomy. Sustainability and wisdom are therefore shown to lie in the maintenance of the capacity for adaptation and change, rather than in the efficiency of any particular temporarily fixed system. Several applications of these ideas are discussed.

The Complexity of Economic Evolution — Change Speeds and Time Scales of nonlinear theory. Firstly, it is argued that economic variables have different change speeds in different societies. Secondly, the significance of time scales in dynamic economic analysis is emphasized. Thirdly, the relationship between change speeds and time scales in dynamic analysis is examin

Investment for Technology Progress, Increasing Marginal Products and Bistable State of Economic Growment. But only when the investment reaches a certain amount, can the level of technology be raised obviously. So there is a large set up cost in the importation of technology and equipment. A S-curve is used in the model to describe this nonlinear property. By the static equilibrium and dynamic anal
