The traditional set stability of Boolean networks (BNs) refers to whether all the states can converge a given state subset. Different from existing results, investigated in this paper is initial destination set. This studies and stabilization avoiding undesirable sets BNs control (BCNs), respectively. First, by virtue semi-tensor product (STP) matrices, dynamics are established. Then, reachabil...

The aim of this study was to evaluate life cycle environmental impacts associated with the generation of electricity from biogas produced by the anaerobic digestion (AD) of agricultural products and waste. Five real plants in Italy were considered, using maize silage, slurry, and tomato waste as feedstocks and cogenerating electricity and heat; the latter is not utilized. The results suggest th...

Nearly all energy conversion systems, and especially electricity generation plants do not operate at nominal conditions throughout their useful life: periodic or semi-periodic changes in the availability of the resource affect solar (thermal and PV), wind, hydraulic and geothermal plants, which in reality operate at off-design conditions for most of their life. To a smaller scale, fossil-fuelle...

in this note we are going to survey several invariants of finite groups related either to their orders or to generating sets or to lattices of subgroups. some relations among these invariants will be exhibited. special attention will be paid to monotonicity of them.
