The wind loads on tall buildings can be estimated from the measurement of the base moments on rigid scale models with a high frequency force balance.
This paper describes an experiment that was carried out in the Twisted Flow Wind Tunnel at The University of Auckland to measure a detailed set of pressure distributions on a rigid 1/15th scale model of a modern asymmetric spinnaker.
Probabilistic calculations of the structural response are carried out in frequency and time domains, and the parameters of the wind velocity field are calibrated on the basis of the time-histories of the global floor forces derived by experimental tests on a rigid 1 500 scale model of the building.
In the first week post-fertilization, the human embryo is dividing on a rigid time scale governed by female reproductive physiology that creates a small window for successful implantation.
In his scathing Nature review of Milne's book, he rejects Milne's hypothetico-deductivism, his cosmological principle, and, above all, his operationalism: "When I visit the Cavendish Laboratory, I do not find its occupants engaged in flashing light-signals at each other, but I find practically everyone employing rigid scales or their equivalent" (Eddington 1935, p. 636).
Tree species of hawkmoth have been recorded to emit ultrasound clicks by rubbing their genitalia; males produce by rubbing rigid scales on the exterior of the claspers while females produce sound by contracting their genitalia which causes rubbing of scales against the abdomen.
Height and weight were measured using a rigid stadiometer and scales DP-7100PWW, Ltd, Hyogo Ltd, Hyogo, Japan).
Height and weight were measured using a rigid stadiometer and calibrated scale.
Given the stereotypic location of cells, registering two worms after straightening is a simple matter of a rigid transformation followed by scaling.
Height to the nearest half centimetre was then measured during quiet breathing, with the horizontal arm of the measuring unit being kept at a rigid right angle to the scale.
