If the average value of w/p observations is below the smallest breakpoint, these pieces are mapped to the symbol ‘a’. If greater than or equal to the smallest breakpoint and less than the second smallest breakpoint, they are mapped to the symbol ‘b’, and the procedure continues up ...
The MPC was developed to control VAV damper position and VAV reheat coil valves in the cooling period and radiant heater valve position was added on top of the two variables in the heating period. As a result, it was proposed that considerable amount of energy could be saved (i.e., ...
FIG. 7 is a diagram of a visual specification of a smart button. The specification may incorporate the font and design of appearance for the smart button. Four states of the smart button may be represented by a symbol94for a normal state, a symbol95for a hover state, a symbol96for a ...
