A heightmap contains one channel interpreted as a distance of displacement or "height" from the "floor" of a surface and sometimes visualized as luma of a grayscale image, with black representing minimum height and white representing maximum height. When the map is rendered, the designer can specify the amount of displacement for each unit of ...
The tape will pulled less than its standard length when a tension less than the standard tension is applied, making the tape too long. A tape stretches in an elastic manner until it reaches its elastic limit, when it will deform permanently and ruin the tape. The correction due to tension is given by:
The top 370m (equivalent to an 85-story building), or 37% of the building's total height, will be unusable. When vanity height is excluded, the height progression of the world's tallest buildings looks much more modest. [4] [5] The CTBUH requires a structure's vanity height to be under 50% to be defined as a "building."
the floor of 1.4 is 1, the ceiling of 1.4 is 2. 1.6 rounded is 2, the floor of 1.6 is 1, the ceiling of 1.6 is 2. So the floor of a fraction is always down; the ceiling of a fraction is always up; rounding can be up or down depending upon whether the fraction is less
The CU value should be obtained by the manufacturer of the luminaire which is to be evaluated. In order to determine the CU on the manufacturer's table, a room cavity ratio (RCR) must be used. Also, the reflectance of the ceiling, walls and floor must be known. RCR = 5 x (room height) x (room width + room length) / [(room width) x (room length ...

Hydrolevelling is an alternative to measuring depth with clinometer and tape that has a long history of use in Russia. [4] The technique is regularly used in building construction for finding two points with the same height, as in levelling a floor.
For the back D-ring height, the distance between the D-ring and the sole of the worker's footwear, employers often use 5 feet as the standard height with the assumption that the worker will be 6 feet in height, but because the D-ring height variability can affect the safety of the system, the back D-ring height must be calculated based on the ...
