Measuring instruments in fiction: Captain Nemo and Professor Aronnax contemplating thermometers, barometers, clocks, etc. in Jules Verne's 1869-1870 science fiction novel Twenty Thousand Leagues Under the Seas Fun measuring instruments: a Love Meter and strength tester machine at a Framingham, Massachusetts rest stop.
Over the entire test period, and also during the last 10 years, the Vortex Indicator showed a better performance than the DMI. [ 7 ] However, using a similar test based on 101 NASDAQ stocks, on a smaller sample (for the period 2 January 1992 to 14 August 2009), the DMI showed a better performance than the Vortex Indicator.
Continuous vortex sheet approximation by panel method. Roll-up of a vortex sheet due to an initial sinusoidal perturbation. Note that the integral in the above equation is a Cauchy principal value integral. The initial condition for a flat vortex sheet with constant strength is (,) =. The flat vortex sheet is an equilibrium solution.
The container compression test measures the compressive strength of packages such as boxes, drums, and cans. It usually provides a plot of deformation vs compressive force . It is commonly used to evaluate shipping containers made of corrugated fiberboard as well as wooden boxes and crates .
A diametral compression test involves applying a stress load or force to the point where a material object is split in half (down the diameter of the object). [1] This test indirectly measures the tensile property of a material object, as the molecules of the material are pushed apart in opposite directions, similar to what happens to molecules in a direct tensile strength test.
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
A vortex flowmeter has the following components: A flow sensor operable to sense pressure variations due to vortex-shedding of a fluid in a passage and to convert the pressure variations to a flow sensor signal, in the form of an electrical signal; and a signal processor operable to receive the flow sensor signal and to generate an output signal corresponding to the pressure variations due to ...
Strength tester may refer to: Grippers , a device used for testing and increasing the strength of the hands High striker , a attraction that operates by utilizing the lever where one end holds a puck attached to the tower and the other end is struck by the person or contestant using a hammer or mallet
