A general discussion is given for first-kind (FK) and quantum non-demolition (QND) measurements. The general conditions for these measurements are derived, including the most general one (called the weak condition), an intermediate one, and the strongest one. The weak condition indicates that we can realize a FK or QND measuring apparatus of wide classes of observables by allowing the apparatus...

Abstract Construction, demolition, and renovation activities generate a significant amount of waste, posing serious environmental risks. The scarcity recycling facilities makes it difficult to implement the new legislation, which calls for producing recycled aggregates. Moreover, lack studies on feasibility construction demolition waste in regions with plentiful natural resources aggregates is ...
