Bayesian Linear Regression: Teaching resources and software

Bayesian models are very important in modern data science. These models can be used to derive estimatesfor noisy and sparse data. This manuscript outlines the basics and derivations of a Bayesian linearregression model. Source code for performing Bayesian linear regression is also provided. I hope thisresource will enable broader understanding of the basics of Bayesian models.

EXAMINATION OF ELECTRIFICATION OF OBJECTS FLYING THROUGH FIRE FUMES

Firstly, a special Faraday cage was used to measure the own electric charge for a model source of fire fumes. The spatial density of the charge, having the sign changing from place to place, does not exceed +/-3 nC/m3. Then, special duralumin projectiles were fired through the produced cloud of fumes with the mean velocity of ca. 150 m/s. The projectiles terminated the flight in a target, the electrode connected to an electrometer, which collected the electric charge accepted during the flight. The established density of the electrification current for projectiles was 30-400 mikro A/m2 what suggests that the charge was collected in the way of triboelectrification rather than by the interception of the fume’s own electric charge.

VOYAGE HISTORIQUE ET POLITIQUE AU MONTÉNÉGRO DE VIALLA DE SOMMIÈRES: UN LIVRE FONDATEUR D’UN IMAGINAIRE PARADOXAL DU VOYAGE AU MONTÉNÉGRO AU XIX SIÈCLE

HISTORICAL AND POLITICAL JOURNEY TO MONTENEGRO BY VIALLA DE SOMMIERES FOUNDING BOOK OF A PARADOXICAL IMAGINARY OF A JOURNEY TO MONTENEGRO In 1820, Vialla de Sommières published in Paris his book Historical and political journey to Montenegro. He was Commander of the Second division of Illyrian army in Ragusa from 1812 to 1813. Later, this work was used by many 19th century French travel writers as a model source for their own observations on Montenegro. Naturally, travelling to an unknown country implies an element of discovery. By analysing de Sommières’s text and the works by other French travel writers (P. Loti, X. Marmier, H. Avelot, J. de la Nézière, F. Lenorment, Ch. Yriarte, M. Sermet, l’abbé P. Bauron) we have been able to situate descriptions of journeys to and throughout Montenegro, which express an effect of surprise or discovery, and we have classified our findings in four sections: difficult access to astonishing landscapes, the cult of freedom, the character of Montenegrins, and the position of women. Thus, a journey to Montenegro becomes a kind of a return to a distant, precarious and, even, timeless epoch. In this sense, Vialla de Sommières’s work constitutes a founding work of a paradoxical imaginary of a journey to Montenegro, as the analysis of this travel story proposes.
