The push force pattern in manual wheelchair propulsion as a balance between cost and effect.

We investigate the hypothesis that the direction of the propulsion force in manual wheelchair propulsion can be interpreted as a result of the balance between the mechanical task requirements and the drivers biomechanical possibilities. We quantify the ...

Limitations in the use and interpretation of continuous relative phase.

Continuous relative phase (CRP), a variable used to quantify intersegmental coordination, is difficult to interpret if care is not taken regarding the assumptions and limitations of the measure. Specifically, CRP is often interpreted as a higher ...

Features of motor performance that drive adaptation in rapid hand movements.

In order to explore how subjects correct for errors in movement and adapt their motor programs, we studied rapid hand movements. Subjects grasped a grooved knob and made brisk turning movements to various targets, similar to tuning a radio dial. A motor ...

Computer simulation as a basis for pharmacy reengineering.

Using computer simulation can enhance the management decision-making process. Simulations can predict the effects on cost and quality of services. This article discusses the use of computer simulation to assist in planning the reengineering process to ...

Movement compatibility for rotary control and circular display--Computer Simulated Test and real Hardware Test.

This experiment studied strength and reversibility of direction-of-motion stereotypes and response times for different configurations of circular displays and rotary knobs. The effect of pointer position, instruction of turn direction, and control plane ...

Instrumental functional diagnostics with the ROSY simulator.

The ROSY robot system has been developed to simulate movements of the jaw under stepper motor control. The areas of indication comprise functional diagnostics and production of designed occlusal splints. Moreover, this device can also be extended for use ...

Testing a positional model of the Hebb effect.

In two experiments, we investigated the hypothesis that a strengthening of position-item associations underlies the improvement seen in performance on an immediate serial recall task, for a list that is surreptitiously repeated every third trial. Having ...

Towards a theory of the laminar architecture of cerebral cortex: computational clues from the visual system.

One of the most exciting and open research frontiers in neuroscience is that of seeking to understand the functional roles of the layers of cerebral cortex. New experimental techniques for probing the laminar circuitry of cortex have recently been ...

Smoothness-based forces for deformable models: a long-range force and a corner fitting force.

Deformable models, originally proposed by Terzopoulos et al. (Artif. Intell. 36 (1988) 91) and Kass et al. (Int. J. Comput. Vision 1 (1988) 321) in 1988, have been widely used in medical image segmentation. However, they manifest two well-known ...
