Squaring-Up Method for Relative Degree Two Plants
Non-square multi-input-multi-output (MIMO) plants are becoming increasingly common, as the addition of multiple sensors is becoming prevalent. However, square systems are needed sometimes as an leverage when it comes to design and analysis, as they possess desirable properties such as strict positive realness. This paper presents a squaring up method that adds artificial inputs to a class of MI...
متن کاملSquaring-up of modulated magnetic structures in HoAg and TmAg
2014 The temperature variation of the amplitude modulated magnetic structures of HoAg and TmAg has been investigated by neutron diffraction on single crystals. A beginning of squaring-up has been observed, but due to experimental conditions the expected antiphase regime could not be fully reached. No locking of the incommensurate propagation vector into commensurate values has been evidenced wi...
متن کاملCarving Up Reality
1. The Problem of the Many Think of Mont Blanc, with its rabbits and foothills and its slurries of moistened rock. We can carve up the reality around Mont Blanc in different ways. If we are hunters, we might include rabbits as parts of the mountain; if we are geologists we might include only rock, perhaps together with a certain amount of air in the crevices and tunnels which have been formed b...
متن کاملPictures in cell biology: squaring up to the cell-shape debate.
These images show bovine capillary endothelial cells growing on square areas of fibronectin (Figs 1 and 2). These squares were generated using a novel process made possible by recent advances in mi-crofabrication technology, which were originally developed for building electronic microchips. Each island of fibronectin is surrounded by a nonadhesive barrier region, so the cell spreads until it r...
متن کاملApproximate Squaring
We study the " approximate squaring " map f (x) := x⌈x⌉ and its behavior when iterated. We conjecture that if f is repeatedly applied to a rational number r = l/d > 1 then eventually an integer will be reached. We prove this when d = 2, and provide evidence that it is true in general by giving an upper bound on the density of the " exceptional set " of numbers which fail to reach an integer. We...
