Abstract: A system for collecting waste objects for recycling including a reverse vending machine, RVM, and a carrier arrangement adapted to receive a devaluated waste object at a first location having a first elevation, and adapted to transport and deliver the devaluated waste object to a second location having a higher elevation than the first location and an inlet of the RVM. The system further includes a buffer arrangement adapted to receive the devaluated waste object from the RVM at a third location and to deliver the devaluated waste object to the carrier arrangement at the first location. The carrier arrangement includes at least one carrier adapted to move repeatedly between the first location and the second location. Further, a process of transporting and collecting waste objects.

Abstract: The invention provides a method for spatially refining a computer generated l-dimensional (l>0) model in a computing environment, the l-dimensional model representing physical or geometrical properties, and where the l-dimensional model is represented by tensor product B-splines basis functions and l-dimensional coefficients, where the l-dimensional coefficients are in real or projective space, and the tensor product B-splines basis functions are spanning an r-variate spline space (r>0) having a parameter domain, the method comprising: a) inserting at least one axis parallel hyper rectangle degenerate in one dimension in said parameter domain, providing a splitting of a support of at least one of said tensor product B-spline basis functions; b) computing refined tensor product B-spline basis functions by subdivision on said at least one tensor product B-splines basis functions whose support is split, using at least one knot value of the at least one axis parallel hyper rectangle; and c) computing the re
