We introduce a methodology for quantitatively measuring at all times in its evolution how close our physical spatially flat [Formula: see text] CDM universe with cosmological constant [Formula: see text] is to the de Sitter spacetime [Formula: see text] with de Sitter radius [Formula: see ...
It then uses this time difference to calculate its own distance to the satellite, whose location it knows (distance = time of travel multiplied by speed of light). Doing this with one satellite places the receiver anywhere on a sphere whose radius is the calculated distance. Doing this ...
In general mathematics, a functional may refer to a function specifically produced from a set ofreal-valued functions.For example, a functional could be the maximum of a set of functions on theclosed interval[0, 1]. Abinary functionaltakes two sets of functions to create one function. For e...
Urbanization and climate change are contributing to severe flooding globally, damaging infrastructure, disrupting economies, and undermining human well-being. Approaches to make cities more resilient to floods are emerging, notably with the design of flood-resilient structures, but relatively little is kno...
Background: My brief is to calculate the temperature inside a metal plate of dimensions 0.8m by 0.4m, this plate is heated in part of the top and left edge to 100 degrees, and cooled in the part of the bottom and right edge at 0 degrees (I believe i h...
The geodesic aspect at a location is the angular direction α of the downslope surface with respect to north, as measured on a plane that is tangent to the ellipsoid surface (the blue plane in the illustration below). To calculate the aspect at each location, a quadratic or biquadratic surfa...
to calculate its quantities, which otherwise can only be obtained from experiments , e.g., the value of the heat capacity, or from approximate phenomenological laws, e.g, the van der Waals equation of state. With these two extensions, statistical mechanics is a complete theory providing the ...
Do you know off the top of your head how to calculate v & h? I’m drawing my hexagons off of a radius, and my implementation of your isInside function is giving me pretty poor hit checks. It is my assumption that: hex.getHeight() returns hexagon.radius * sqrt(3); ...
This paper utilizes the entropy method of empowerment and dimensionality reduction to calculate the composite score of col- lege students' goal clarity. Self‑monitoring Drawing on related research on self-monitoring scales and com- bining the traits of Chinese college students (Ji et al.,...
Q: Since the real-world does all kinds of crazy calculations in no time, can we use physics to calculate stuff? Q: Is there some way to actually play quidditch? Q: Can you poke something that’s far away with a stick faster than it would take light to get there? Q: Does how you...
