Abstract: Ovaj rad ima za cilj da sagleda Sonju Sever u kontekstu pripadnosti slovenačkoj književnoj tradiciji, ali istovremeno i zajedničkom književnom sistemu socijalističke Jugoslavije. Posebna pažnja pri analizi dela ove autorke posvećena je i različitim aspektima socrealističke poetike, koja predstavlja dominantan diskurs u proznom opusu Sonje Sever za decu i omladinu na srpskohrvatskom jeziku. U ovom radu, na primerima romana Mali Kinez Kong i Majko, zašto? pokazuje se na koji način je socrealistička poetika uticala na kompoziciju dela, oblikovanje likova i ideologizovanje pogleda na svet. Fokus naučnog istraživanja usmeren je i na načine na koje autorka uspeva da prevaziđe uske okvire i matrice ove stilske formacije, ukrsti je sa specifičnim zahtevima i funkcijama književnosti za decu i omladinu, te ostvari po mnogo čemu umetnički uspela dela.

Abstract: The main aim of the dissertation is to develop a meshless model that describes the solidification and macrosegregation phenomena during the direct chill casting (DCC) of aluminium alloys under the influence of a low-frequency electromagnetic field. Macrosegregation is an undesired consequence of alloy solidification. It represents one of the major casting defects and substantially reduces the quality of the finished product. On the other hand, low-frequency electromagnetic casting (LFEC) is a process that promises to increase greatly the product quality, including the reduction of macrosegregation. The modelling of both processes is of tremendous importance to the metallurgical industry, due to the high costs of experiments during production. The volume-averaging formulation is used for the modelling of the solid-liquid interaction. The conservation equations for mass, energy, momentum, and species are used to model the solidification of aluminium-alloy billets in axysimmetry. The electromagnetic-induction equation is coupled with the melt flow. It is used to calculate the magnetic vector potential and the Lorentz force. The Lorentz force is time-averaged and included in the momentum-conservation equation, which intensifies the melt flow. The effect of Joule heating is neglected in the energy conservation due to its insignificant contribution. The semi-continuous casting process is modelled with the Eulerian approach. This implies that the global computational domain is fixed in space. The inflow of the liquid melt is assumed at the top boundary and the outflow of the solid metal is assumed at the bottom. It is assumed that the whole mushy area is a rigid porous media, which is modelled with the Darcy law. The Kozeny-Carman relation is used for the permeability definition. The incompressible mass conservation is ensured by the pressure correction, which is performed with the fractional step method. The conservation equations and the induction equation are posed in the cylindrical coordinate system. A linearised eutectic binary phase diagram is used to predict the solute redistribution in the solid and liquid phases. The micro model uses the lever rule to determine the temperature and the liquid fraction field from the transport equations. The partial differential equations are solved with the meshless-diffuse-approximate method (DAM). The DAM uses weighted least squares to determine a locally smooth approximation from a discrete set of data. The second-order polynomials are used as the trial functions, while the Gaussian function is used as the weight function. The method is localised by defining a smooth approximation for each computational node separately. This is performed by associating each node with a unique local neighbourhood, which is used for the minimisation. There are 14 nodes included in the local subdomains for the DCC and LFEC simulations. The stability of the advective term is achieved with a shift of the Gaussian weight in the upwind direction. This approach is called the adaptive upwind weight function and is used in the DAM for the first time. The Explicit-Euler scheme is used for temporal discretisation. The use of a meshless method and the automatic node-arrangement generation makes it possible to investigate the complicated flow structures, which are formed in geometrically complex inflow conditions in a straightforward way. A realistic inflow geometry and mould can therefore be included in the model. The number of computational nodes is increased in the mushy zone and decreased in the solid phase, due to the optimisation of the computational time and memory. The computational node arrangement is automatically adapted with time, as the position of the mushy zone is changed in shape and position.

Abstract: Večerja tačasne resničnosti spremljevalni dogodek Večerja v umetniškem vzdušju se odvije: v torek, 3. oktobra, ob 19. uri v Layerjevi hiši, Tomšičeva 32, Kranj Večerja je del razstave À Mon Seul Désir, ki preko vseh čutov ter opremljena z multimedijskimi vsebinami v povečani resničnosti tematizira žensko prozo. Evropske pisateljice in njihova življenja so avtorji razstave Narvika Bovcon, Vanja Mervič in Aleš Vaupotič secirali do potankosti, podatke vizualizirali in nas popeljali na potovanje preko plasti čutnega. Zaključek razstave, ki si jo lahko s pomočjo aplikacije za uvid v obogateno resničnost ogledate v galeriji Mahlerca v Layerjevi hiši, bo pospremila večerja, pripravljena po receptih velikih pisateljic Virginie Woolf, Sylvie Plath in Anais Nin. Vse tri jedi so klasične za enega od delov Evrope. Menu: Bajtarska štruca po receptu Virginie Woolf ("Cottage Loaf") Testenine bolognese po receptu Anais Nin ("Pasta bolognese") Sladek paradižnikov kolač po receptu Sylvie Plath ("Tomato Soup Cake") Kuha in peče: Sara Hostnik, slikarka, slaščičarka in kuharica Udeležba: min. 10 oseb / max. 20 oseb Prijavite se preko emaila: info@layer.si do ponedeljka, 2. 10. Cena večerje je 5 € za eno osebo in 8 € za par. Dober tek!
