Exciton coupling in coordination compounds

Dalton Transactions, 2011
This Perspective reviews the impact of exciton coupling on the spectroscopic properties of coordination compounds. Exciton coupling features arise in electronic absorption and circular dichroism spectra when chromophores are brought into close spatial proximity, for example by coordination to a metal centre.

Intercerebellar Coupling Contributes to Bimanual Coordination

Journal of Cognitive Neuroscience, 2007
Abstract Compared to unimanual task execution, simultaneous bimanual tapping tasks are associated with a significantly reduced intertap variability. It has been suggested that this bimanual advantage is based on the integration of timing signals which otherwise control each hand independently.

Negotiation of coupled constraints in coordinated vehicles

49th IEEE Conference on Decision and Control (CDC), 2010
We derive and establish properties for an algorithm for the distributed optimization of a global constrained optimization problem through the limited communication of data between cooperating subsystems; each subsystem solves a local optimization problem. The structure of the optimization problem is such that it is performed by the distinct subsystems,

Experimental substructure coupling with rotational coupling coordinates

26th Structures, Structural Dynamics, and Materials Conference, 1985
A substructure coupling method based on experimentally measured data, including rotational coupling coordinates, is presented. The required rotational displacements at the interface are determined from the measured trnnslati.ona1 mode shapes by cubic spli.ne interpolation.

Coupling dynamics in interlimb coordination.

Journal of Experimental Psychology: Human Perception and Performance, 1993
In 1:1 frequency locking, the interlimb phase difference phi is an order parameter quantifying the spatial-temporal organization of 2 rhythmic subsystems. Dynamical modeling and experimental analyses indicate that an intentional parameter phi psi (intended coordination mode, phi = 0 degrees or phi = 180 degrees) and 2 control parameters omega c ...

Spatial Coupling in the Coordination of Complex Actions

The Quarterly Journal of Experimental Psychology A, 1997
The majority of investigations on coordinated action have focused on temporal constraints in movements. Recent studies have demonstrated spatial constraints when the hands produce different trajectory shapes simultaneously. The focus of the current study was to determine whether spatial coupling occurs in individual parameters of the actions, or ...

Optimizing Vibrational Coordinates To Modulate Intermode Coupling

Journal of Chemical Theory and Computation, 2016
The choice of coordinate system strongly affects the convergence properties of vibrational structure computations. Two methods for efficient generation of improved vibrational coordinates are presented and justified by analysis of a model anharmonic two-mode Hessian and numerical computations on polyatomic molecules.

Coordinate Mastering Using Optical Coupling

SPIE Proceedings, 1989
For a multi-sensor machine vision system, relating each sensor's measurement to a master gage coordinate system has been a difficult task. This is especially true for sheet metal gaging in the automotive industry where sensors may be separated by four or five meters.

Model of Coupled or Dissociated Eye-Head Coordination

Journal of Vestibular Research, 1994
Tight coupling between eye and head movements have been observed in response to a single visual target offset or a single flash. On this basis, when the visual stimulus consists of two successive steps or flashes in the same (horizontal) direction, either increasing in eccentricity or decreasing in eccentricity, gaze should be due to concomitant eye ...
