PF expresses the ratio of true power used in a circuit to the apparent power delivered to the circuit. A 96% power factor demonstrates more efficiency than a 75% power factor. PF below 95% is considered inefficient in many regions. PF expresses the ratio of true power used in a circuit ...
To calculate FOV for your display measure the width of the display, straight across horizontally. Then measure the distance your eyes are from the screen. The FOV is defined by: FOV = arctan(screen_width * 0.5 / eye_distance) * 2.0 VP4 takes FOV in degrees so set your calculater to d...
Good points triplemon. I could start cutting and creep up on the end length but that's a chore I'd rather avoid. Newt For the Web shows the current seconday of 3.1" giving a .44" fully illuminated FOV with only 19% obstruction so hopefully that will be ok since I'm a visual obse...
Calculate a scale error. For example,if the building appears to be 12 meters across but should be 18, thescale erroris .666 – so the height above ground is 66% of the correct value. Or if scale appears 25% too large – for example,. a football field appears to be 125 yards...
SAR = [(0.5 x γ x B1rms x √(TR x TE) x SAR/B1) / (π x FOV x slice thickness)] x number of slices x patient weight Where: γ: gyromagnetic ratio = 42.58 MHz/T B1rms: root-mean-square (RMS) of the B1 field SAR/B1: specific absorption rate per unit B1 field ...

What is the Exit Pupil of Binoculars and How do You Calculate It? If you hold the binoculars up to a bright background or light with the oculars facing you about 10 inches from your eyes, you'll see a bright beam or circle of light - this is the exit pupil. ...
To calculate the exit pupil divide the objective lens size by magnification. So the higher the magnification, the larger the objective lens needed to maintain image brightness. As a general rule of thumb, try to get a scope where the exit pupil is 1.33mm or more. ...
Calculate average and standard deviation of both the DUT thermometer readings and readings taken from the 4180 display. Calculate DUT error by subtracting DUT average from the 4180 average. Resources and useful links ASTM E1965-98 Specification for Infrared Thermometers fo...
cameraLookat = Vector3.Transform( cameraLookat, Matrix.CreateRotationY( avatarYaw ) ); // Calculate the position the camera is looking at. cameraLookat += cameraPosition; // Set up the view matrix and projection matrix. view = Matrix.CreateLookAt( cameraPosition, cameraLookat, new Vector...
