The SAD PERSONS scale is an acronym utilized as a mnemonic device. It was first developed as a clinical assessment tool for medical professionals to determine suicide risk , by Patterson et al. [ 1 ] The Adapted-SAD PERSONS Scale was developed by Gerald A. Juhnke for use with children in 1996.
Selected area (electron) diffraction (abbreviated as SAD or SAED) is a crystallographic experimental technique typically performed using a transmission electron microscope (TEM). It is a specific case of electron diffraction used primarily in material science and solid state physics as one of the most common experimental techniques.
Today, selenium-SAD is commonly used for experimental phasing due to the development of methods for selenomethionine incorporation into recombinant proteins. SAD is sometimes called "single-wavelength anomalous dispersion" , but no dispersive differences are used in this technique since the data are collected at a single wavelength.
The Severity of Alcohol Dependence Questionnaire (SADQ or SAD-Q) is a 20 item clinical screening tool designed to measure the presence and level of alcohol dependence. [1] It is divided into five sections: Physical withdrawal symptoms; Affective withdrawal symptoms; Craving and relief drinking; Typical daily consumption
The SAD-512 was a single delay line version. The Philips Semiconductors TDA1022 [ 3 ] similarly offered a 512-stage delay line but with a clock rate range of 5–500 kHz. Other common BBD chips include the Panasonic MN3002, MN3005, [ 4 ] MN3007, [ 5 ] MN3204 and MN3205, [ 6 ] with the primary differences being the available delay time.

The sum of absolute transformed differences (SATD) is a block matching criterion widely used in fractional motion estimation for video compression.It works by taking a frequency transform, usually a Hadamard transform, of the differences between the pixels in the original block and the corresponding pixels in the block being used for comparison.
