Economically, Hassan II adopted a market-based economy, where agriculture, tourism, and phosphates mining industries played a major role. The period from the 1960s to the late 1980s was labelled as the "years of lead" and saw thousands of dissidents jailed, killed, exiled or forcibly disappeared. King Hassan II had extended many parliamentary functions by the early 1990s and released hundreds of political prisoners in 1991, and allowed the Alternance, where the opposition assumed power, for the first time in the Arab World. He set up a Royal Council for Human
ASCEND ASCEND ASCEND is an open source, mathematical modelling chemical process modelling system developed at Carnegie Mellon University since late 1978. ASCEND is an acronym which stands for Advanced System for Computations in Engineering Design. Its main uses have been in the field of chemical process modelling although its capabilities are general. ASCEND includes nonlinear algebraic solvers, differential/algebraic equation solvers, nonlinear optimization and modelling of multi-region 'conditional models'. Its matrix operations are supported by an efficient sparse matrix solver called "mtx". ASCEND differs from earlier modelling systems because it separates the solving strategy from model building. So domain experts (people writing
