Accuracy of measurement of the signal information parameter tracking meter in the aviation and space rocket industry technology against the background of additive and multiplicative interference. The steepness of the discriminatory specifications. Part I

Рассмотрено и проанализировано влияние мультипликативных помех, действующих одновременного с аддитивными помехами, на точность измерения одного информационного параметра следящим измерителем. Проанализирована крутизна дискриминационной характеристики следящего измерителя . The influence of multiplicative interference acting simultaneously with additive interference on the accuracy of measurement of a single information parameter by a tracking meter is considered and analyzed. The steepness of the discrimination characteristic of the tracking meter is analyzed.

Brazilian Black Theatre: A Political Theatre Against Racism

Black Brazilian theatre constitutes a political and artistic response to the racial discrimination characteristic of Brazilian society. As early as 1944, young members of the recently created black political movement saw theatre as a potential weapon to transform Brazilian society and created the Teatro Experimental do Negro (Black Experimental Theatre). This activist theatre continues to this day to pave the way for other black theatre companies.
