Modelling and numerical approximation of a 2.5D set of equations for mesoscale atmospheric processes

The set of 3D inviscid primitive equations for the atmosphere is dimensionally reduced by a Discontinuous Galerkin discretization in one horizontal direction. The resulting model is a 2D system of balance laws where with a source term depending on the layering procedure and the choice of coupling fluxes, which is established in terms of upwind considerations. The "2.5D" system is discretized via a WENO-TVD scheme based in a flux limiter centered approach. We study four tests cases related to atmospheric phenomena to analyze the physical validity of the model

A review of source term estimation methods for atmospheric dispersion events using static or mobile sensors

Understanding atmospheric transport and dispersal events has an important role in a range of scenarios. Of particular importance is aiding in emergency response after an intentional or accidental chemical, biological or radiological (CBR) release. In the event of a CBR release, it is desirable to know the current and future spatial extent of the contaminant as well as its location in order to aid decision makers in emergency response. Many dispersion phenomena may be opaque or clear, thus monitoring them using visual methods will be difficult or impossible. In these scenarios, relevant concentration sensors are required to detect the substance where they can form a static network on the ground or be placed upon mobile platforms. This paper presents a review of techniques used to gain information about atmospheric dispersion events using static or mobile sensors. The review is concluded with a discussion on the current limitations of the state of the art and recommendations for future research.close

Contemporary textbooks and compedia of knowledge for primary schools children and adolescents

Praca zawiera omówienie zagadnień związanych z problematyką współczesnych podręczników i kompendiów wiedzy dla uczniów szkół podstawowych. Podczas badań wykorzystano metodę analizy i krytyki piśmiennictwa oraz metodę statystyczną. Na początku zaprezentowano historię podręczników od 1945 roku, charakterystykę elementów budowy zewnętrznej, ceny, ich znaczenie na rynku wydawniczym, a także we współczesnej edukacji wczesnoszkolnej. Następnie przedstawiono analizę badań przeprowadzonych z udziałem 156 uczniów z klas od 1 do 3 szkół podstawowych, których celem był pomiar wagowy dzieci, plecaków oraz ich zawartości. Na podstawie otrzymanych wyników ustalono, iż prawie 80% badanych uczniów nosiło nadmiernie obciążone plecaki. Oprócz problematyki drukowanych podręczników szkolnych scharakteryzowano podręczniki elektroniczne, jako nowe narzędzie dydaktyczne we współczesnej szkole.The thesis aims to present the issues related to contemporary textbooks and compendia of knowledge in the context of an elementary school students. A statistical method and critical analysis of the literature has been used to perform the studies. To begin, a history of textbooks since 1945 was presented, then characteristics of the elements, as well as their importance in the publishing market and their role in contemporary early childhood education. The work presents an analysis of the study, which aim was to measure the weight of 156 primary school children, also their backpacks with contents. Based on these results, it seems that almost 80% of the students wore overloaded backpacks. In addition to this, electronic textbooks have been characterized as a new teaching tool in the modern school
