WebFortunately, symmetrical design does not depend on identical mirroring. It’s only important to get close to the effect; exactitude is not necessary. Remember, you can manipulate the user’s eye easily without worrying about geometric perfection as a consideration in your design. Conversely, asymmetry is the absence of symmetry of any kind. WebResults: In 19 scans (9.5%), there was an asymmetry between the height of the fovea ethmoidalis on the right and left sides. Of these 19, 12 (63.2%) were lower on the right side, whereas 7 (36.8%) were lower on the left. Ninety-six patients (48.0%) demonstrated a contour asymmetry with "flattening" of the ethmoid roof on one side, 46 on the ...

WebThe mean absolute percentage error ( MAPE ), also known as mean absolute percentage deviation ( MAPD ), is a measure of prediction accuracy of a forecasting method in statistics. It usually expresses the accuracy as a ratio defined by the formula: where At is the actual value and Ft is the forecast value.
