The demography is a quantitative science that was established on a statistical base, but it has quickly developed its own methods and research elements in response to the particularity of demographic phenomenon and to its real need of specific elem ents of measuring and analysis that exceed what applied statistics propose. And even if demography meets with many other sciences, yet it has a particularity that results firstly from the effect of time on its events, and secondly from the fact that the demographic events are submitted to a necessary order that must be taken in consideration when we pass from demographic to social analysis of elements and data. This research illuminates this particularity of the necessary order in demographic events, through two access: the first treats time as a demographic concept and how it is related to the necessary order of demographic events; and the second treats the effect of this necessary order in the social analysis of the events that both demography and sociology are interested in, in order to show the importance of gathering demographic and social analysis when treating different demographic-social events, and to illustrate the shortfalls that may affect some models of social analysis if it's not preceded by a demographic analysis of the studied event.
Calculation of fire resistance for any structural member divided in two independent steps . The first step involves predicting the temperature distribution inside the structural members, referred to as ‘thermal analysis’. The second step of the analy sis, termed the ‘structural analysis’, is carried out for the main purpose of determining the response of the structure due to static and thermal loading. The first stages of analysis are discussed in this paper, using finite element method by a structural analysis program " ANSYS "
Using data from English cloze tests, in which subjects also self-reported their gender, age, education, and race, we examine performance differences of pretrained language models across demographic groups, defined by these (protected) attributes. We demonstrate wide performance gaps across demographic groups and show that pretrained language models systematically disfavor young non-white male speakers; i.e., not only do pretrained language models learn social biases (stereotypical associations) -- pretrained language models also learn sociolectal biases, learning to speak more like some than like others. We show, however, that, with the exception of BERT models, larger pretrained language models reduce some the performance gaps between majority and minority groups.
Visual analysis of flocculation caused by the bacteria Microthrix parvicella isolated from domestic sewage was studied in the laboratory using synthetic sewage with the addition of different coagulants: FeCl٣, AICI٣, AI٢ (SO٤)٣ and FeSO٤.
