72. Umetniški slog animiranih likov zahoda in vzhodaMiha Oven, 2019, undergraduate thesis Abstract: Diplomska naloga se osredotoča na analizo sloga oblikovanja videza lika za animirani film v primerjavi med ameriško in japonsko animacijo. Slog oblikovanja videza animiranega lika opredeljujemo na podlagi različnih področij. Mednje uvrščamo navidezne značaje lika, raznolikost zgradb telesa, strukturo obraza, oblikovanje prepoznavnih značilnosti silhuet lika, metode in tehnike za dosego učinkov zgradb delov telesa (roke, noge …), ustvarjanje karakterističnih lastnosti same silhuete, predhodno pripravo s specifičnimi smernicami videza lika za animiranje (določitev velikosti lika, barvne lestvice, upoštevanje terminov emocij …) in ne nazadnje doseganje različnih učinkov gibanja.
Cilj diplomske naloge je analizirati razlike in enakosti ameriške in japonske animacije (ameriški animirani film Osmosis Jones in japonska animirana serija Cells at Work!), ki si zasluženo delita vodilno mesto po vplivu v svetu animiranega medija.
Diplomska naloga je sestavljena iz teoretičnega in empiričnega dela. V teoretičnem delu so razloženi pojmi in strokovni termini s pomočjo tujih avtorjev in virov. Vsebina teoretičnega dela se smiselno nadaljuje v empiričnem delu z analizo področij, obrazloženih v teoretičnem delu. Torej, kot je v teoretičnem delu razložena silhueta v animaciji, je tudi v empiričnem delu analizirana silhueta v ameriški in japonski animaciji.

73. The role of charge transfer at reduced graphene oxide/organic semiconductor interface on the charge transport propertiesGvido Bratina, Egon Pavlica, 2019, original scientific article Abstract: The effect of 1-pyrenesulfonicacid sodium salt (1-PSA), tetracyanoethylene (TCNE) and tetrafluoro- tetracyanoquinodimethane (F4-TCNQ) on charge transport properties of reduced graphene oxide (RGO) is examined by measuring the transfer characteristics of field-effect transistors and co-planar time-of-flight photocurrent technique. Evidence of p-type doping and a reduction of mobility of electrons in RGO upon deposition of these materials is observed. Time-resolved photocurrent measurements show a reduction in elec- tron mobility even at submonolayer coverage of these materials. The variation of transit time with different coverages reveals that electron mobility decreases with increasing the surface coverage of 1-PSA, TCNE and F4- TCNQ to a certain extent, while at higher coverage the electron mobility is slightly recovered. All three molecules show the same trend in charge carrier mobility variation with coverage, but with different magnitude. Among all three molecules, 1-PSA acts as weak electron acceptor compared to TCNE and F4-TCNQ. The additional fluorine moieties in F4-TCNQ provides excellent electron withdrawing capability compared to TCNE. The experimental results are consistent with the density functional theory calculations.

74. Determination of Dissolved Iron Redox Species in Freshwater Sediment using DGT Technique Coupled to BDSHanna Budasheva, Aleksander Kravos, Dorota Korte, Arne Bratkič, Yue Gao, Mladen Franko, 2019, original scientific article Abstract: In this work we have developed a novel method for determination of iron redox species by the use of diffusive gradients in thin-film (DGT) technique coupled to photothermal beam deflection spectroscopy (BDS). The combination of both methods achieved low limit of detection (LOD) of 0.14 μM for Fe (II) ions. The total Fe concentration determined in the Vrtojbica river sediment (Slovenia, Rožna Dolina, 5000 Nova Gorica) was 49.3 μgL–1. The Fe (II) and Fe (III) concentra- tion amounted to 12.8 μgL–1 and 39.9 μgL–1, respectively. Such an approach opens new opportunities for monitoring the content of iron species in natural waters and sediments and provides highly sensitive chemical analysis and an accurate qualitative and quantitative characteristic of the materials under study.

75. The Road Movie : a Journey of Rebellion and Self-DiscoveryAnna Loi, 2018, undergraduate thesis Abstract: Film Ceste je pojav s širokimi družbenimi in kulturnimi posledicami. Pričujoče diplomsko delo
analizira značilnosti tega žanra, pri čemer upošteva nekatere najpomembnejše filme, ki so se
izkazali za ključne za razvoj žanra. V povojnem obdobju, ko se je družba spreminjala, ko se je
ponovno pojavil optimizem in ko se je življenjski standard povzpel do točke, da si je tudi srednji
sloj lahko privoščil potovanja brez posebnega razloga, je postal tako imenovani “road movie”
oziroma film ceste množični ameriški pojav, ki je bil v veliki meri je bil povezan tudi s
prostranostjo ZDA in z njenimi temeljnimi kulturnimi spremembami. Ta filmski žanr se je kmalu
razširil po vsem svetu in ustvaril lastna pravila in zgodovino, postal pa je tudi glasnik generacije 60.
let 20. stoletja. Do danes se filmi ceste še vedno dotikajo teme samospoznavanja in odkrivanja in
pogosto ne predstavljajo le fizičnega, temveč tudi metaforično potovanje vase, prav tako pa zelo
pogosto vsebujejo politično izjavo. Keywords: potovanje, film, cesta, upor, samospoznavanje Published in RUNG: 19.12.2018; Views: 4314; Downloads: 57 Full text (94,16 MB) This document has many files! More... |
76. Otroci v slovenskem celovečernem filmuMery Gobec, 2018, master's thesis Abstract: Magistrsko delo Otroci v slovenskem celovečernem filmu obravnava razvoj otroškega in mladinskega slovenskega filma. Pri tem se sprašuje predvsem, v kakšni vlogi nastopajo otroci, katere ideološke misli podajajo in na kakšen način je njihova umestitev v zgodbo indikator političnega, socialnega in družbeno-kulturnega stanja v našem prostoru. V magistrsko delo je vključen tudi kronološki pregled otroških in mladinskih filmov, ki veljajo za najpomembnejše v slovenski kinematografiji. Ugotavljam, da se je idejna sporočilnost slovenskih celovečernih filmov z otroki spreminjala glede na ustaljen politični sistem. Če so obravnavani filmi vse od 50. let dalje pogosto podajali misel o partizanskem junaštvu in pomembnosti protiokupatorskega boja (nekateri obravnavani filmi pa izražajo idejo kvarnega vpliva tujcev in drugačnih, do česar v magistrski nalogi zavzemam kritičen odnos) so v 70. in 80. letih že izražali kritično misel o tedanjem sistemu. S prihodom 80. in 90. let (in »nove dobe«) je očiten vse pogostejši vpliv ameriške pop kulture in hollywoodskega filma. Seveda ne v vseh primerih, a vendar je očitno, da se mnogi filmi tovrstnega žanra še vedno držijo manj in bolj opaznih kompleksov, ki se jih slovenski otroški in mladinski film očitno še ni uspel popolnoma znebiti.

78. Post Colonial Dilettantes : The Aesthetics Of Anti-ImperialismRajat Sharma, 2018, master's thesis Abstract: The thesis begins a discourse into a need of an Indian film theory by exploring and
analysing the plenitude of relevant western theories. In order to do so it lays down certain
concrete relationships between ideologies, terminologies and their effect; as in what
exactly post colonial means, why it is important to understand the impact of colonisation
on culture and thus on one of the most mass consumed medium in India; films. The thesis
explores the depths and complexity of the relationship of these two and the other
influences that sprout from it for example the intensity of colonisation as a cultural project
and its influence on the social reality of the people, artists, thinkers (and in our case
specifically filmmakers) , who in turn reflect on this culture through various mediums
including films. The thesis examines the western plethora of film theory in order to
accentuate the contrast between film and cinema in the west and east and thus the
subsequent need to bring forth a new ‘Eastern Film theory’.

79. PHOTO-EXCITATION ENERGY INFLUENCE ON THE PHOTOCONDUCTIVITY OF ORGANIC SEMICONDUCTORSNadiia Pastukhova, 2018, doctoral dissertation Abstract: In this work, we experimentally studied the influence of photoexcitation energy
influence on the charge transport in organic semiconductors. Organic semiconductors
were small molecules like corannulene, perylene and pentacene derivatives, polymers
such as polythiophene and benzothiophene derivatives, and graphene, along with
combinations of these materials in heterojunctions or composites.
The first part of this study is focused on the photoexcitation energy influence on
the transient photoconductivity of non-crystalline curved π-conjugated corannulene
layers. The enhanced photoconductivity, in the energy range where optical absorption
is absent, is deduced from theoretical predictions of corannulene gas-phase excited
state spectra. Theoretical analysis reveals a consistent contribution involving
transitions to Super Atomic Molecular Orbitals (SAMOs), a unique set of diffuse
orbitals typical of curved π-conjugated molecules. More, the photoconductivity of the
curved corannulene was compared to the π-conjugated planar N,N′-1H,1H-
perfluorobutyldicyanoperylene-carboxydi-imide
(PDIF-CN2),
where
the
photoexcitation energy dependence of photocurrent closely follows the optical
absorption spectrum.
We next characterized charge transport in poly(3-hexylthiophene) (P3HT) layers
deposited from solution. Our results indicate that time-of-flight (TOF) mobility
depends on the photoexcitation energy. It is 0.4× 10 −3 cm 2 /Vs at 2.3 eV (530 nm) and
doubles at 4.8 eV (260 nm). TOF mobility was compared to field-effect (FET) mobility
of P3HT field-effect transistors (OFETs). The FET mobility was similar to the 2.3 eV
excitation TOF mobility. In order to improve charge mobility, graphene nanoparticles
were blended within a P3HT solution before the deposition. We found that the mobility
significantly improves upon the addition of graphene nanoparticles of a weight ratio
as low as 0.2 %. FET mobility increases with graphene concentration up to a value of
2.3× 10 −2 cm 2 /Vs at 3.2 %. The results demonstrate that phase segregation starts to
influence charge transport at graphene concentration of 0.8 % and above. Hence, the
graphene cannot form a bridged conduction channel between electrodes, which would
cancel the semiconducting effect of the polymer composite.
An alternative approach to enhance mobility is to optimize the molecular ordering
of organic semiconductors. For that purpose, we studied an innovative nanomesh
device. Free-standing nanomesh devices were used to form nanojunctions of N,N′-
iiDioctyl-3,4,9,10-perylenedicarboximide (PTCDI-C8) nanowires and crystalline
bis(triisopropylsilylethinyl)pentacene (TIPS-PEN). We characterized the photocurrent
response time of this novel nanomesh scaffold device. The photoresponse time
depends on the photon energy. It is between 4.5 − 5.6 ns at 500 nm excitation
wavelength and between 6.7 − 7.7 ns at 700 nm excitation wavelength. In addition, we
found that thermal annealing reduces charge carrier trapping in crystalline nanowires.
This confirms that the structural defects are crucial to obtaining high photon-to-charge
conversion efficiency and subsequent transport from pn junction in heterostructured
materials.
Structural defects also influence the power conversion efficiency of organic
heterostructured photovoltaics (OPVs). Anticipating that polymers with different
backbone lengths produce different level of structural defects, we examined charge
transport
dependence
on
the
molecular
weight
of
poly[4,8-bis(5-(2-
ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b']dithiophene-2,6-diyl-alt-(4-(2-
ethylhexyl)-3-fluorothieno[3,4-b]thiophene-)-2-carboxylate-2-6-diyl]
(PTB7-Th)
from 50 kDa to 300 kDa. We found p-type hopping transport in PTB7-Th,
characterized by 0.1 – 3× 10 −2 cm 2 /Vs mobility, which increases with temperature and
electric field. The polymer molecular weight exhibits a non-trivial influence on charge
transport. FET mobility in the saturation regime increases with molecular weight. A
similar trend is observed in TOF mobility and FET mobility in the linear regime,
except for the 100kDa polymer, which manifests in the highest mobility due to reduced
charge trapping. The lowest trapping at the dielectric interface of OFET is observed at
200 kDa. In addition, the 200 kDa polymer exhibits the lowest activation energy of the
charge transport. Although the 100 kDa polymer indicates the highest mobility, OPVs
using the 200 kDa polymer exhibit the best performance in terms of power conversion
efficiency. Keywords: organic

80. Jacques Tati : Življenje kot igriščeTaja Košir Popovič, 2018, undergraduate thesis Abstract: Diplomsko delo povezuje raziskovalni in praktični del. Išče stičišča med ustvarjalnim opusom režiserja Jacquesa Tatischeffa – Tatija in avtorskim kratkim igranim filmom Ondine, ki ga je avtorica zasnovala in režirala.
Naloga govori nad navdušenjem subtilnega izražanja velikega umetnika Tatija. Njegov občutek za opazovanje ljudi ter vživljanje v njihovo psiho in značaje je avtorico nagovoril, da je tudi v svojem pristopu do raziskovanja možnosti oblikovanja značajev glavnih junakov filma Ondine globje vstopila v proučevanje vzvodov, ki narekujejo naše obnašanje, reakcije, interakcije. Prav tako jo je očarala Tatijeva sposobnost za vživljanje v komične, na trenutke absurdne prizore, ki jih spretno niza v nove, nenavadne situacije. Te gledalca presenetijo in nasmejijo. Ob estetiki, ki je brezčasna in zelo avtorsko zaznamovana, aktualna tako v času nastanka Tatijevih filmov kot danes, je prepoznala še eno stično točko s tem, kako v svojem avtorskem pristopu dojema prostor in čas, kaj zanjo pomeni lepota.
V prvem, teoretičnem delu zato predstavlja Tatija in njegov umetniški opus in s tem zariše polje, znotraj katerega se giblje njen način ustvarjanja. Povezuje življenjsko pot režiserja in igralca, izbrane filme, nato pa se podrobneje posveti filmu Playtime in ključnim gradnikom, ki jih je avtor sestavil v neponovljiv filmski izraz.
Drugi, praktični del, prikazuje avtoričino pot – zakaj in kako se je lotila snovanja filma Ondine, kaj jo je navdihovalo in kje je našla odgovore na ustvarjalne izzive pri Tatiju. Nadaljuje s predstavitvijo procesa priprav, snemanja in post-produkcije filma.
