Hm - OPTIMAL CONTROLLER DISCRETIZATION
A redesign method for discretizing a continuous-time controller is proposed. The resulting hybrid control system, for example with continuous-time plant and discrete-time controller, is stable, and performance including the system's inter-sampling behaviour can be optimized by approximating some chosen reference transfer function of the continuous-time control system. In order to obtain a tract...
متن کاملhm(P) = h1(Pm): Alternative Characterisations of the Generalisation From hmax To hm
The hm (m = 1, . . .) family of admissible heuristics for STRIPS planning with additive costs generalise the h heuristic, which results when m = 1. We show that the step from h to hm can be made by changing the planning problem instead of the heuristic function. This furthers our understanding of the hm heuristic, and may inspire application of the same generalisation to admissible heuristics s...
متن کاملHM⁺ and HM⁺‑He (M = Group 2 metal): chemical or physical interactions?
We investigate the HM(+)‑He complexes (M = Group 2 metal) using quantum chemistry. Equilibrium geometries are linear for M = Be and Mg, and bent for M = Ca-Ra; the explanation for this lies in the differing nature of the highest occupied molecular orbitals in the two sets of complexes. The difference primarily occurs as a result of the formation of the H-M(+) bond, and so the HM(+) diatomics ar...
متن کامل[99mTc]-HM-PAO SPECT in Parkinson's disease.
Thirty-six patients affected by Parkinson's disease were studied using single photon emission computed tomography (SPECT) and [99mTc]-HM-PAO as a tracer. The scanning procedure was performed 16-24 h after discontinuation of specific therapy. Tracer activity ratios were determined in 10 pairs of cerebellar, cortical, and subcortical regions. Data were compared with those of 10 age-matched contro...
متن کاملHM 802 February 8 , 2013 1 Preamble
The notes below will serve as the basis for the module lectures to be given on the topics of Jordan form, nonnegative matrices, and Markov chains. As you'll see, most of the proofs have been omitted in the notes. The intention is to sketch the proofs during the lectures, but also to have the students work through some of the details (using references such as those listed at the end of this docu...
