1. Paranoia in ImagesRoberta Battiston, 2015, undergraduate thesis Abstract: “Strah” je resnični problem z resnično rešitvijo, medtem ko je “paranoja” nekaj
kar je nezavedno ustvarjeno v naših mislih in jih lahko tako popolnoma prevzame,
je t.i. “naprava moči”, kot v svoji teoriji navaja Michel Foucault. Na področju
umetnosti, se je s tem fenomenom ukvarjalo že mnogo umetnikov, med katerimi so
umetniško gibanje Preraphaelites, Vincent Van Gogh, ekspresionizem z Edvardom
Munchem, Jamesom Ensorjem, Emilom Noldom, Egonom Schielom in Oskarjem
Kokoshko, prav tako pa tudi surrealizem z slikarji kot so Salvador Dali, Renè
Magritte in Max Ernst, so razsikovali področja sanj in domišljije. V fotografiji so
pričeli raziskovati notranji svet človeškega bitja, najprej skozi piktorialistično
gibanje nato pa še čez surrealizem v katerem so se umetniki kot Man Ray, André
Kertész, Hans Bellmer, Philippe Halsman pričeli z eksperimentirati z novimi
tehnikami. Lewis Carroll se je vdano posvetil fotografiranju mlade deklice nekje v
sredini 19. stoletja. Temo otroštva je raziskovala tudi Loretta Lux. Med neosurrealističnime
fotografe lahko spadajo Jerry Uelsmann, Robert in Shana Parke
Harrison, Scarlota Ban, Brooke Shaden, Meggie Taylor, Robert Kusterle, Maurizio
Frullani, Serigo Culoto, Sergio Scabar, Ingalisa Maria Fina, Enzo Tedeschi, Lorella
Klun, Jennifer B Thoreson (Hudson) in Joel Peter Witkin. Jaques Rancière in Roland
Barthes na z svojimi teorijami podajata ključ za branje slik v ne-seriji “Tempus
Fugit, paranoia manent”. V svoji raziskavi sem želela raziskati zgodovinski razvoj
povezave med umetniki in paranojo v namen razumevanja kako se je aktualna
tema razvijala skozi leta in jo uporabiti kot začetno točko na poti do ustvarjanja
svojega vizualnega jezika.

2. Large-Scale Distribution of Arrival Directions of Cosmic Rays Detected at the Pierre Auger Observatory and the Telescope Array above 10[sup]19 eVMarko Zavrtanik, Danilo Zavrtanik, Lili Yang, Serguei Vorobiov, Darko Veberič, Marta Trini, Samo Stanič, Ahmed Saleh, Gašper Kukec Mezek, Andrej Filipčič, Olivier Deligny, 2015, published scientific conference contribution Abstract: The large-scale distribution of arrival directions of
high-energy cosmic rays is a key observable in attempts to
understanding their origin. The dipole and quadrupole moments
are of special interest in revealing potential anisotropies.
An unambiguous measurement of these moments as well as
of the full set of spherical harmonic coefficients requires
full-sky coverage. This can be achieved by combining data from
observatories located in both the northern and southern
hemispheres. To this end, a joint analysis using data recorded
at the Pierre Auger Observatory and the Telescope Array above
10[sup]19 eV has been performed. Thanks to the full-sky
coverage, the measurement of the dipole moment reported in
this study does not rely on any assumption on the underlying
flux of cosmic rays. As well, the resolution on the quadrupole
and higher order moments is the best ever obtained. The
resulting multipolar expansion of the flux of cosmic rays
allows a series of anisotropy searches to be performed,
and in particular to report on the first angular power
spectrum of cosmic rays. This allows a comprehensive
description of the angular distribution of cosmic rays
above 10[sup]19 eV.

4. Bora wind, Wind speed vertical profile, Logarithmic law, Power lawKlemen Bergant, Samo Stanič, Marija Bervida, 2018, published scientific conference contribution Abstract: Bora is cold and gusty downslope wind with variable gust frequency and duration, appearing on the lee side of Dinaric Alps. Its flow characteristics are unique and theoretically still not fully described, especially for modeling purposes. We present an analysis of the wind speed vertical profiles at Razdrto, which lies in a gap between the Nanos and Javorniki plateau in southwest Slovenia and is strongly exposed to Bora. An analysis of the vertical wind speed profiles during Bora episodes is based on experimental wind data, provided by Helikopter energija, for six Bora events of different duration, appearing between April 2010 and May 2011. Average wind speed in 10-minute intervals was collected at four different heights (20, 31, 40 and 41.7 m above the ground)at the wind turbine site in Razdrto using cup anemometers. Wind direction data with same temporal resolution was obtained from a single wind vane placed at 40.9 m above the ground. Based on the collected data, the applicability of the empirical power-law and the logarithmic law profiles, commonly used for the description of neutrally stratified atmosphere, was investigated for the case of Bora. The parameters for the power-law and logarithmic law were obtained by fitting the wind speed data using linear regression method and are compared to standard values for that particular type of terrain. The quality of fits was very good with r2 above 0.9, indicating that both power-law and logarithmic law adequately describe mean horizontal Bora wind. The median value of the power-law coefficient was found to be 0.16±0.03, which is consistent with standard value for neutral atmosphere (0.143). The aerodynamic roughness varied from 0.003 m to 0.22 m with the median value of 0.09±0.07, which describes open level country terrain with some trees. The event in November 2010 with large roughness is expected to be due to specific wind direction and surface conditions.

5. Near-Ground Profile of Bora Wind Speed at Razdrto, SloveniaKlemen Bergant, Samo Stanič, Marija Bervida, Benedikt Strajnar, 2019, original scientific article Abstract: Southwest Slovenia is a region well-known for frequent episodes of strong and gusty Bora wind, which may damage structures, affect traffic, and poses threats to human safety in general. With the increased availability of computational power, the interest in high resolution modeling of Bora on local scales is growing. To model it adequately, the flow characteristics of Bora should be experimentally investigated and parameterized. This study presents the analysis of wind speed vertical profiles at Razdrto, Slovenia, a location strongly exposed to Bora during six Bora episodes of different duration, appearing between April 2010 and May 2011. The empirical power law and the logarithmic law for Bora wind, commonly used for the description of neutrally stratified atmosphere, were evaluated for 10-min averaged wind speed data measured at four different heights. Power law and logarithmic law wind speed profiles, which are commonly used in high resolution computational models, were found to approximate well the measured data. The obtained power law coefficient and logarithmic law parameters, which are for modeling purposes commonly taken to be constant for a specific site, were found to vary significantly between different Bora episodes, most notably due to different wind direction over complex terrain. To increase modeling precision, the effects of local topography on wind profile parameters needs to be experimentally assessed and implemented.

7. A pyrrolopyridazinedione-based copolymer for fullerene-free organic solar cellsAstrid-Caroline Knall, Samuel Rabensteiner, Sebastian F. Hoefler, Matiss Reinfelds, Mathias Hobisch, Heike M. A. Ehmann, Nadiia Pastukhova, Egon Pavlica, Gvido Bratina, Illie Hanzu, Shuguang Wen, Renqiang Yang, Gregor Trimmel, Thomas Rath, 2021, original scientific article Abstract: The recent success of non-fullerene acceptors in organic photovoltaics also entails a change in the requirements to the polymer donor in terms of optical and morphological properties leading to a demand for novel conjugated polymers. Herein, we report on the synthesis of a 1,4-bis-(thiophene-2-yl)-pyrrolopyridazinedione based copolymer with 2-ethylhexyl substituents on the pyrrolopyridazinedione moiety. A 2D conjugated benzodithiophene (BDT) was chosen as comonomer. The resulting copolymer T-EHPPD-T-EHBDT showed a molecular weight of 10.2 kDa, an optical band gap of 1.79 eV, a hole mobility of 1.8 × 10−4 cm2 V−1 s−1 and a preferred face-on orientation with regard to the substrate. The comparably wide band gap as well as the determined energy levels (HOMO: −5.47 eV, LUMO: −3.68 eV) match well with the narrow band gap non-fullerene acceptor ITIC-F, which was used as the acceptor phase in the bulk heterojunction absorber layers in the investigated solar cells. The solar cells, prepared in inverted architecture, revealed power conversion efficiencies up to 7.4% using a donor:acceptor ratio of 1 : 1 in the absorber layer.
