Inherent difficulties with active control equivalence studies.
A simple model is used to investigate the relevance of 'competence' to active control equivalence studies (ACES). It is shown that to the extent that such trials are successful the results of such trials must raise doubts regarding their competence. ACES are thus more problematic than classical clinical trials and the problems with such studies cannot be solved simply by exchanging the usual ro...
متن کاملThe inherent appeal of physically controlled peripherals
Computer game controllers that require the user to interact using physical movements (other than finger movements) are becoming increasingly popular. The present study sought to explore the factors and context which impact upon preferences for particular physically controlled game peripherals. A comprehensive user study was undertaken and both qualitative and quantitative data were analysed. Th...
متن کاملAn active biopolymer network controlled by molecular motors.
We describe an active polymer network in which processive molecular motors control network elasticity. This system consists of actin filaments cross-linked by filamin A (FLNa) and contracted by bipolar filaments of muscle myosin II. The myosin motors stiffen the network by more than two orders of magnitude by pulling on actin filaments anchored in the network by FLNa cross-links, thereby genera...
متن کاملDesign and Characterization of an Aerostatic Spherical Bearing
An aerostatic spherical bearing has been developed for parallel kinematic machines. The design is based on a ball and socket configuration and is preloaded by permanent magnets arranged about the socket. High pressure air is injected through three orifices into the cavity between the ball and socket to produce a low friction, high accuracy interface. Joint accuracy is measured using a coordinat...
متن کاملTest Pattern Generation with Restrictors
This paper extends state-of-the-art ATPG systems by including constraints, called restrictors, on the allowable values of the bits of a test vector. Such restrictors often occur in ’realworld’ circuits where certain bit positions of a test vector have to take on a particular value (e.g. in case of a reset line) or are prohibited from taking on a particular value (e.g. in order to prevent an ill...
