Prediction by partial matching (PPM) is an adaptive statistical data compression technique based on context modeling and prediction. PPM models use a set of previous symbols in the uncompressed symbol stream to predict the next symbol in the stream. PPM algorithms can also be used to cluster data into predicted groupings in cluster analysis.

The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
Perez, the girl’s mother, allegedly told police they placed the toddler in her crib around 7 p.m. the night before with a space heater turned as high as it could be set and did not check on her ...
WASHINGTON — Sen. Elizabeth Warren, D-Mass., signaled that she may back Rep. Lori Chavez-DeRemer, R-Ore., for labor secretary, a major progressive figure being willing to work with President ...
Temperature coefficients as low as 1.5–2.0 ppm/°C can be obtained with bandgap references. [a] However, the parabolic characteristic of voltage versus temperature means that a single figure in ppm/°C does not adequately describe the behavior of the circuit. Manufacturers' data sheets show that the temperature at which the peak (or trough ...

Pulse-position modulation (PPM) is a form of signal modulation in which M message bits are encoded by transmitting a single pulse in one of possible required time shifts. [ 1 ] [ 2 ] This is repeated every T seconds, such that the transmitted bit rate is M / T {\displaystyle M/T} bits per second.
