We study divisibilities between bounded holomorphic quasi-inner functions in H∞ and operator-valued bounded holomorphic quasi-inner functions in H∞(Ω, L(K)) where Ω is a bounded finitely connected region. Furthermore, we characterize these divisibilities by using rationally-invariant subspaces.

A framework for force and visual control of robot manipulators in contact with a partially known environment is proposed. The environment is modelled as a rigid object of known geometry but of unknown and time-varying pose. An algorithm for online estimation of the object pose is adopted, based on visual data as well as on force measurements. This information is used by a force/position control...

The numbers on the inner circle are those that exist in the modular arithmetic. If we continue beyond 7, as shown in the outer ring, the numbers wrap around the wheel. Numbers on the same spoke are equivalent. For example, 0 and 8 are equivalent, 1 and 9 are equivalent, 2 and 10 are equivalent, and so on. Another way to look at it is that when 9 is introduced into modular arithmetic with 8 shaf...

STUDY OBJECTIVE The purpose of the study was to assess the accuracy of Family Practitioner Committee (FPC) lists for identifying very elderly people registered with general practitioners. DESIGN The accuracy of available FPC lists was checked against the most recent electoral register to determine which recorded individuals were still living at their FPC registered addresses. This was followe...
