Computing wind turbine output power with linear regression.

a wind turbine manufacturer provides the power produced by the turbine (outputpwrdata) given various wind speeds (windspeeddata). a straight line fits the measured output power well for mid-range wind speeds (6-12 m/s). use linear regression to fit a first-order polynomial (straight line) to estimate output power given a mid-range input windspeed.

isolate the measured values used for fitting:

assign windspeedfitdata with windspeeddata in mid range of wind speeds (6-12 m/s)

assign outputpwrfitdata with outputpwrdata in mid range of wind speeds (6-12 m/s)

calculate the first-order polynomial coefficients that fits the isolated values:

assign outputpwrcoefs with linear regression coefficients

make use of coefficients to calculate the value of the polynomial at input windspeed

assign outputpwrest with estimate calculated using linear regression coefficients

Creating "smart interfaces" in all sectors of industry, government, and the public arena is one of the fastest growing hct areas. these interfaces model, interpret, and analyze such human characteristics as speech, gesture, and vision. the field of biometrics, in which humans authenticate themselves to machines, is an area of considerable interest to hct practitioners. fingerprint scans are one of the most frequently used biometric options, and this article, biometric student identification: practical solutions for accountability & security in schools, makes a case for the implementation of fingerprint scans in schools. critique the article, and answer the following questions: according to the author, what are the main benefits of adopting fingerprint scans in schools for student identification? according to the author, what are the main drawbacks of adopting fingerprint scans in schools for student identification? do you agree with the author's assessment of the pl
