If you have only been sleeping on your side, the technician may come into the room at some point and ask you to try to sleep on your back. If you never sleep on your back or cannot sleep on your back you do not need to do this in the study. Should I drink alcohol on the night of the sleep study?
To calculate the cross sectional area (CSA) of a cable, you have to use a micrometer to verify its diameter, then divide the diameter by two to get the radius (r).With the ra â¦ dius we can calculate the CSA of the cable.    CSA = pi x r2 (Applicable to solid wires only).se the formula pi x r2 (3.14 x radius x radius) to get the cross sectional area. The formula works for all measurement units whether they are inches, millimeters, centimeters or others. An alternative is to use (pi x d^2)/4. (3.14x diameter x diameter divided by 4) You do not then need to divide the original diameter.
What is a 'Cross-Sectional Analysis' Cross-sectional analysis is a type of analysis that an investor, analyst or portfolio manager may conduct on a company in relation to that company's industry or industry peers. The analysis compares one company against the industry in which it operates, or directly against certain competitors within the same industry, in an attempt to assess performance and investment opportunities.
