On logics and semantics for interpretability
-
Luka Mikec In this thesis we will study various properties of formalised relativised interpretability. In the central part of this thesis we study for different interpretability logics the following aspects: completeness for modal semantics, decidability and algorithmic complexity. In particular, we will study two basic types of relational semantics for interpretability logics. One is the Veltman semantics, which we shall refer to as the regular or ordinary semantics; the other is called generalised...

Opažanja i modeliranje klimatskih trendova temperature zraka i mora za jadransko područje
-
Slavko Radilović Klimatska predviđanja temperatura zraka i mora u obalnim područjima predstavljaju veliki izazov zbog kompleksnih međudjelovanja između atmosfere, mora i kopna. Pošto je Sredozemlje proglašeno jednim od mjesta na Zemlji gdje su klimatske promjene najizraženije, regionalni klimatski modeli (Regional Climate Models, RCMs) i reanalize su zbog toga najpoželjniji alati za istraživanje sastava lokalne klime i promjenjivosti iste. Prednost je u tome što RCM-i bolje prikazuju kompleksnu...

Optical and structural properties of ultrathin films on noble metals
-
Martin Lončarić Ultrathin layers of noble metals obtained by deposition to the substrate during evaporation in high vacuum represent nanostructured matter. Nanoparticles showing interesting optical properties due to the localized surface plasmons are formed instead of homogenous layer. Optical properties of noble metal nanoparticles are closely related to their size, shape, distribution and dielectric environment. Localized surface plasmon properties may be tailored by changing deposition parameters (amount...

Optics of van der Waals layered systems
-
Valentino Jadriško The bandgaps of many atomically thin 2D layered materials such as graphene, blackphosphorus, semiconducting transition metal dichalcogenides (TMDs) and hBN range from 0 to 6eV. These isolated atomic planes can be reassembled in van der Waals (vdW) two-dimensional (2D) layered structures with precisely chosen vdW stacking sequences and interlayer coupling, which opens the avenues for creating new materials systems with rich functionalities and novel electronic and optical properties....

Optimality criteria method for optimal design problems
-
Ivana Crnjac In this thesis, we study numerical solutions for optimal design problems. In such problems, the goal is to find an arrangement of given materials within the domain which minimizes (or maximizes) a particular integral functional, under constraints on the amount of materials and PDE constraints that underlay involved physics. We consider such problems in the frame of the stationary diffusion equation and linearized elasticity system for domains occupied by two isotropic materials. In Chapter 1...

Optimiranje metode elektrodepozicije alfa-izvora s naglaskom na vrstu elektrolita i materijal katode
-
Matea Krmpotić U doktorskom radu ispitana je i optimirana metoda elektrodepozicije za pripremu (semi)kvantitativnih alfa-izvora upotrebom nekoliko vrsta elektrolita u kombinaciji s različitim materijalima katoda. Ispitivani parametri odnosili su se na sastav i koncentracije odabranih elektrolita, primijenjenu jakost struje, vrijeme trajanja elektrodepozicije, volumen elektrolita te udaljenost anoda-katoda, kao i uvjete za termičku obradu pripremljenih alfa-izvora prije mjerenja. Pri tome je korištena...

Optimizacija sinteze omeprazola potpomognuta termodinamičkim istraživanjima
-
Nina Vojčić Opisana je optimizacija proizvodnog postupka sinteze djelatne tvari omeprazola. Svojstva tog
spoja, kao i njegovih sintetskih prekursora, temeljito su proučena fizikalno-kemijskim
istraživanjima procesa protonacije i otapanja. Određene su konstante ravnoteže protonacijskih
reakcija i termodinamičke veličine vezane uz solvataciju, tj. topljivost polaznih spojeva i
međuprodukta te entalpije i entropije njihova otapanja. S obzirom da je opisana optimizacija
temeljena na modifikaciji...

Optoelectronic properties of the poly(3,4-ethylenedioxythiophene) : polystyrene sulphonate thin films in varied doping states
-
Gaurav Pathak Poly(3,4 ethylenedioxythiophene): polystyrenesulfonate (PEDOT:PSS) has gained considerable attention in the past decade due to its novel applications in the field of flexible electronics. PEDOT:PSS is the leading candidate for the channel material in the organic electrochemical transistor (OECT) devices. While PEDOT:PSS has been reported to provide high values of transconductance in transistor devices, the fundamental physical understanding of electrochemical gating of conducting polymers is...

Orbitne matrice jako regularnih grafova
-
Marija Maksimović Predmet istraživanja doktorske disertacije čine konstrukcija orbitnih matrica jako regularnih grafova za djelovanje neke grupe automorfizama, te konstrukcija jako regularnih grafova i samo ortogonalnih kodova iz dobivenih orbitnih matrica. U disertaciji je generaliziran algoritam za konstrukciju orbitnih matrica jako regularnih grafova uz pretpostavljeno djelovanje grupe automorfizama prostog reda, kojega su 2011. godine objavili M. Behbahani i C. Lam. Generalizacija je rezultirala...
