Verses of Faith and Devotion. Seeing, Reading, and Touching Monumental Crucifixes with Inscriptions (12th–13th century)

The paper discusses a group of monumental crucifixes from the 13th-century East Adriatic and Italy, pained or executed in low relief, that display a verse inscriptions on the transverse limb of the cross. The main scope of the paper is to examine the provenance of the text inscribed in order to yield clearer insight into their function, use and original location in the church interiors. The paper specifically aims at analyzing three monumental crucifixes from the East-Adriatic city of Zadar which, although have already been the subject of a respectable number of studies, have not attracted attention as objects of devotion. My interest, therefore, is turned towards verse inscription as their distinctive feature and, as I shall argue, a key aspect in understanding their function. Examining the nature of the text displayed, iconography and materiality of these crucifixes, my main argument is to demonstrate how these objects provoked a multi-faced response from their audience, since were experienced by seeing, hearing and touching respectively

Programming with a Differentiable Forth Interpreter

Given that in practice training data is scarce for all but a small set of problems, a core question is how to incorporate prior knowledge into a model. In this paper, we consider the case of prior procedural knowledge for neural networks, such as knowing how a program should traverse a sequence, but not what local actions should be performed at each step. To this end, we present an end-to-end differentiable interpreter for the programming language Forth which enables programmers to write program sketches with slots that can be filled with behaviour trained from program input-output data. We can optimise this behaviour directly through gradient descent techniques on user-specified objectives, and also integrate the program into any larger neural computation graph. We show empirically that our interpreter is able to effectively leverage different levels of prior program structure and learn complex behaviours such as sequence sorting and addition. When connected to outputs of an LSTM and trained jointly, our interpreter achieves state-of-the-art accuracy for end-to-end reasoning about quantities expressed in natural language stories.Comment: 34th International Conference on Machine Learning (ICML 2017

Hladne pukotine u zavarenim spojevima

U današnje vrijeme ne postoji djelatnost kod koje se ne javljaju pogreške, pa tako je i kod zavarivanja, pogreška sasvim normalna pojava. U samom uvodu završnog rada, navedeni su općeniti pojmovi o zavarivanju, odnosno zavarljivosti. Tema ovog završnog rada su pogreške koje se mogu pojaviti tijekom, te nakon zavarivanja. Opisana je podjela pogrešaka redom: pukotine, šupljine - poroznost, čvrsti uključci, naljepljivanje i nedovoljan provar, pogreške oblika zavara, te ostale pogreške. Navedeni su glavni uzroci nastajanja pogrešaka i načini na koji bi se one mogle "ublažiti", odnosno smanjiti. U nastavku rada, detaljnije je opisana jedna skupina pogrešaka, a to su pukotine. Pukotine su jedne od najčešćih pogrešaka koje se pojavljuju kad je u pitanju zavarivanje. Pukotine se dijele na tople i hladne pukotine. Opisan je nastanak hladnih pukotina i pojašnjeni su glavni uzroci nastanka. Navede su i opisane metode ispitivanja hladnih pukotina, te na koji način se one mogu umanjiti. Na kraju rada su objašnjene metode kojima je moguće ispitivati hladne pukotine. To su Implant metoda, Tekken metoda, CTS metoda (engl. Control Thermal Severity) i Lehigh metoda

Projekt grijanja poslovne zgrade sustavom s dizalicom topline

U ovom završnom radu je proračunat i projektiran sustav grijanja poslovne zgrade prema zadanoj arhitektonskoj podlozi. Zgrada se nalazi na području grada Hvara na otoku Hvaru. Sustav grijanja je predviđen kao niskotemperaturni s dizalicom topline tlo-voda i s podnim grijanjem temperaturnog režima 35/30 ̊ C. Proračun projektnih toplinskih gubitaka je proveden prema normi HRN EN 12 831. Proračun godišnje potrebne toplinske energije je proveden prema normi HRN EN ISO 13 790. Prema ovoj normi zgrada je također svrstana u pripadajući energetski razred. Podno grijanje je dimenzionirano prema dijagramima proizvođača na temelju izračunatih toplinskih gubitaka svake prostorije. Sustav grijanja je opremljen sa svom potrebnom armaturom i regulacijskim elementima potrebnim za potpuno automatski rad. Uz rad je priložena i tehnička dokumentacija koja se sastoji od nacrta na kojima je definiran smještaj opreme po etažama, te je priložena i funkcionalna shema spajanja opreme te shema automatske regulacije

Numerička aproksimacija modela poroelastične ljuske

U ovom radu uveli smo model poroelastične ljuske Naghdijevog tipa, koji je najsličniji modelu elastične ljuske opisanom u [9, 8]. Za razliku od modela poroelastične ljuske opisanom u [5] model opisan u radu uz fleksijske dopušta i membranske efekte. Glavni rezultat u radu su dokaz egzistencije i jedinstvenosti sustava. Dokaz jedinstvenosti rješenja temelji se na metodi energija, dok se egzistencija temelji na iterativnom postupku sličnom numeričkoj metodi opisanoj u [4]. Na kraju smo i pokazali neke numeričke aproksimacije rješenja modela u dva slučaja zanimljiva u primjeni, poput filtera u automobilima. Metoda dokaza egzistencije rješenja i numerička metoda kojom smo dobili rezultate u zadnjem poglavlju nisu ista metoda. Stoga je cilj daljnje istraživanje usmjeriti ka implementaciji prve numeričke metode i formalnom opravdanju druge.In this thesis we introduced the poroelastic shell model of Naghdi’s type, which is the most similar to the elastic shell model described in [9, 8]. While the poroelastic shell model described in [5] captures only bending effects, the model introduced in this thesis captures membrane effects, as well. The main result in this thesis is the proof of existence and uniqueness of the system of equations. The proof of uniqueness is based on the energy method, while the proof of existence is based on iterative procedure similar to the numerical method described in [4]. At the end, we showed numerical approximation of solutions of the model in two cases interesting in application, such as car filters. The method which we used in the proof of existence of solutions and numerical method which we used to obtain numerical results are not the same method. Thus, our goal is to extend our research to implementation of the first method and justification of the second one

Partial Dynamical Symmetry and Anharmonicity in Gamma-Soft Nuclei

Partial dynamical symmetry is shown to be relevant for describing the anharmonicity of excited bands in $^{196}$Pt while retaining solvability and good SO(6) symmetry for the ground band.Comment: 4 pages, 1 figure, Proc.
