Pivalic acid is a carboxylic acid with a molecular formula of (CH 3) 3 CCO 2 H. This colourless, odiferous organic compound is solid at room temperature. Two abbreviations for pivalic acid are t-BuC(O)OH and PivOH.
Isobutyl formate (2-methylpropyl methanoate) is an organic ester with the chemical formula C 5 H 10 O 2.It is formed by the Fischer esterification of isobutanol with formic acid, with the aid of an acid catalyst.
Barker codes of length N equal to 11 and 13 are used in direct-sequence spread spectrum and pulse compression radar systems because of their low autocorrelation properties (the sidelobe level of amplitude of the Barker codes is 1/N that of the peak signal). [15]
It is an example of Fortran code that performs a variety of spectral line analysis and spectrum synthesis tasks under the assumption of local thermodynamic equilibrium. Moog uses a model photosphere together with a list of atomic or molecular transitions to generate an emergent spectrum by solving the equation of radiative transfer .
Spread Spectrum Time Domain Reflectometry, for instance, involves sending down a spread spectrum signal down a wire line to detect wire faults. [10] Several clustering methods have also been proposed to identify the novel fault and segment a given signal into normal and faulty segments.
The ZX Interface 1, launched in 1983, was a peripheral from Sinclair Research for its ZX Spectrum home computer. Originally intended as a local area network interface for use in school classrooms, it was revised before launch to also act as the controller for up to eight ZX Microdrive high-speed tape-loop cartridge drives.
Amateur radio operators began experimenting with packet radio in 1978, when—after obtaining authorization from the Canadian government—Robert Rouleau, VE2PY; Bram Frank, VE2BFH; Norm Pearl, VE2BQS; and Jacques Orsali, VE2EHP [2] of the Montreal Amateur Radio Club Montreal, Quebec, began experimenting with transmitting ASCII encoded data over VHF amateur radio frequencies using homebuilt ...
