11. DOJEMANJE FOTOKNJIG SKOZI VSEBINSKE IN OBLIKOVNE STRUKTUREAljaž Lavrič, 2023, undergraduate thesis Abstract: V teoretičnem delu diplomske naloge razpravljam o zgodovini razvoja
fotoknjig ter njihovih vsebinskih in oblikovnih prvinah, skozi katere avtorji
dosegajo različne želene učinke, ki jih format fotoknjige ponuja. Vsako prvino
podkrepim in ilustriram s konkretnim primerom sodobne fotoknjige za lažjo
predstavo in razumevanje.
Podatke sem začel zbirati v knjižnicah in knjigarnah, znanje pa sem poglobil
z dvema intervjujema s slovenskima umetnikoma Tadejem Vaukmanom in
Bojanom Radovičem ter pomanjkljive informacije dopolnil z brskanjem po
spletu.
Problema sem se lotil, ker sem želel globlje razumeti vlogo fotoknjig v svetu
fotografije. Želel sem ugotoviti, kakšne vrste fotoknjig poznamo in razumeti,
zakaj in kako določene fotoknjige gledalca uspešno nagovarjajo ter preprosto
učinkujejo kot samostojno umetniško delo.

13. Nova topografija : diplomsko deloMatej Turk, 2022, undergraduate thesis Abstract: V diplomskem delu je najprej na kratko obrazložen pojem »nova topografija« in od kje izvira sam izraz. Nato sledi opis pojma pokrajina in kaj je ta pojem pomenil v slikarski umetnosti, zatem pa še opis pokrajine v fotografijah in kako so te krajinske fotografije prešle iz funkcionalnosti v umetnost. Besedilo nato nekoliko podrobneje opiše razstavo New Topographics (Rochester, New York, 1975) in avtorska dela sodelujočih avtorjev. Po predstavitvi razstave sledi opis objektivnega stila fotografije, ki je bil ključnega pomena za razstavo, in kako je ta vplival na kasnejše fotografe, ki pa se niso osredotočali zgolj na krajinsko fotografijo. Teoretični del se konča s predstavitvijo štirih avtorjev – Bernd in Hilla Becher, Edward Burtynsky in pa Chris Jordan, ki so bili velik navdih za fotografije v praktičnem delu moje diplomske naloge in pa po mojem mnenju tudi pomembni predstavniki fotografske razstave New Topographics. Nato sledi praktični del diplomske naloge z opisom moje fotografske serije Barje s priloženimi fotografijami.

14. Investigation of Aerosol Types and Vertical Distributions Using Polarization Raman Lidar over Vipava ValleyLonglong Wang, Marija Bervida, Samo Stanič, Klemen Bergant, Asta Gregorič, Luka Drinovec, Zhenping Yin, Yang Yi, Detlef Müller, Xuan Wang, 2022, original scientific article Abstract: Aerosol direct radiative forcing is strongly dependent on aerosol distributions and aerosol types. A detailed understanding of such information is still missing at the Alpine region, which currently undergoes amplified climate warming. Our goal was to study the vertical variability of aerosol types within and above the Vipava valley (45.87◦ N, 13.90◦ E, 125 m a.s.l.) to reveal the vertical impact of each particular aerosol type on this region, a representative complex terrain in the Alpine region which often suffers from air pollution in the wintertime. This investigation was performed using the entire dataset of a dual-wavelength polarization Raman lidar system, which covers 33 nights from September to December 2017. The lidar provides measurements from midnight to early morning (typically from 00:00 to 06:00 CET) to provide aerosol-type dependent properties, which include particle linear depolarization ratio, lidar ratio at 355 nm and the aerosol backscatter Ångström exponent between 355 nm and 1064 nm. These aerosol properties were compared with similar studies, and the aerosol types were identified by the measured aerosol optical properties. Primary anthropogenic aerosols within the valley are mainly emitted from two sources: individual domestic heating systems, which mostly use biomass fuel, and traffic emissions. Natural aerosols, such as mineral dust and sea salt, are mostly transported over large distances. A mixture of two or more aerosol types was generally found. The aerosol characterization and statistical properties of vertical aerosol distributions were performed up to 3 km.

15. Odstopanja od motošportne fotografijeLuka Carlevaris, 2022, undergraduate thesis Abstract: Diplomsko delo Odstopanja od motošportne fotografije obravnava dva žanra športne fotografije. Naloga je razdeljena na dva dela. Ker je v središče praktičnega dela diplome postavljena tema avtomobilističnih dirk, prvi del govori o motošportu in fotografiji, ki se ukvarja s tem področjem. Predstavlja njen razvoj od začetka do danes. Dotika pa se tudi njenega tehnološkega razvoja.
Pri izdelavi fotografske serije ni bila uporabljena klasična reportažna fotografija, zato se drugi del posveča osebnemu pristopu fotografiranja športa, katerega končni izdelki so konceptualna dela, ki jih nismo vajeni videvati v medijih in reklamah, saj ne prikazujejo vrhuncev športnega dogajanja in zmagovalcev.
Za temo raziskovanja je bilo določeno, kako lahko fotograf predstavi samega sebe skozi fotografijo športa. Namen je, da bi bralec spoznal, da je fotografska serija, ki na prvi pogled ni umetniške narave, lahko osebno izpovedna.
Po teoretičnem delu sledi opis praktičnega dela diplomske naloge, fotografske serije z naslovom Barve hitrosti. Ta ne predstavlja motošporta kot takega, ampak avtorja in njegov pogled kot oboževalca tovrstnega športa, ki ne posveča pozornosti zgolj avtom in dirkačem, temveč tudi gledalcem, mehanikom, atmosferi in detajlom.
Keywords: Športna fotografija, motošportna fotografija, avtomobilistične dirke, drugačen pristop, fotografska serija

16. A dual-wavelength photothermal aerosol absorption monitor : design, calibration and performanceLuka Drinovec, Uroš Jagodič, Luka Pirker, Miha Škarabot, Mario Kurtjak, Kristijan Vidović, Luca Ferrero, Bradley Visser, Jannis Röhrbein, Ernest Weingartner, Daniel M. Kalbermatter, Konstantina Vasilatou, Griša Močnik, 2022, original scientific article Abstract: There exists a lack of aerosol absorption measurement techniques with low uncertainties and without artefacts. We have developed the two-wavelength Photothermal Aerosol Absorption Monitor (PTAAM-2λ), which measures the aerosol absorption coefficient at 532 and 1064 nm. Here we describe its design, calibration and mode of operation and evaluate its applicability, limits and uncertainties. The 532 nm channel was calibrated with ∼ 1 µmol mol−1 NO2, whereas the 1064 nm channel was calibrated using measured size distribution spectra of nigrosin particles and a Mie calculation. Since the aerosolized nigrosin used for calibration was dry, we determined the imaginary part of the refractive index of nigrosin from the absorbance measurements on solid thin film samples. The obtained refractive index differed considerably from the one determined using aqueous nigrosin solution. PTAAM-2λ has no scattering artefact and features very low uncertainties: 4 % and 6 % for the absorption coefficient at 532 and 1064 nm, respectively, and 9 % for the absorption Ångström exponent. The artefact-free nature of the measurement method allowed us to investigate the artefacts of filter photometers. Both the Aethalometer AE33 and CLAP suffer from cross-sensitivity to scattering – this scattering artefact is most pronounced for particles smaller than 70 nm. We observed a strong dependence of the filter multiple scattering parameter on the particle size in the 100–500 nm range. The results from the winter ambient campaign in Ljubljana showed similar multiple scattering parameter values for ambient aerosols and laboratory experiments. The spectral dependence of this parameter resulted in AE33 reporting the absorption Ångström exponent for different soot samples with values biased 0.23–0.35 higher than the PTAAM-2λ measurement. Photothermal interferometry is a promising method for reference aerosol absorption measurements.

17. The impact of temperature inversions on black carbon and particle mass concentrations in a mountainous areaKristina Glojek, Griša Močnik, Honey Dawn C. Alas, Andrea Cuesta-Mosquera, Luka Drinovec, Asta Gregorič, Matej Ogrin, Kay Weinhold, Irena Ježek, Martin Rigler, Maja Remškar, Miha Markelj, 2022, original scientific article Abstract: Residential wood combustion is a widespread practice in Europe with a serious impact on air quality, especially in mountainous areas. While there is a significant number of studies conducted in deep urbanized valleys and basins, little is known about the air pollution processes in rural shallow hollows, where around 30 % of the people in mountainous areas across Europe live. We aim to determine the influence of ground temperature inversions on wood combustion aerosol pollution in hilly, rural areas. The study uses Retje karst hollow (Loški Potok, Slovenia) as a representative site for mountainous and hilly rural areas in central and south-eastern Europe with residential wood combustion. Sampling with a mobile monitoring platform along the hollow was performed in December 2017 and January 2018. The backpack mobile monitoring platform was used for the determination of equivalent black carbon (eBC) and particulate matter (PM) mass concentrations along the hollow. To ensure high quality of mobile measurement data, intercomparisons of mobile instruments with reference instruments were performed at two air quality stations during every run. Our study showed that aerosol pollution events in the relief depression were associated with high local emission intensities originating almost entirely from residential wood burning and shallow temperature inversions (58 m on average). The eBC and PM mass concentrations showed stronger associations with the potential temperature gradient (R2=0.8) than with any other meteorological parameters taken into account (ambient temperature, relative humidity, wind speed, wind direction, and precipitation). The strong association between the potential temperature gradient and pollutant concentrations suggests that even a small number of emission sources (total 243 households in the studied hollow) in similar hilly and mountainous rural areas with frequent temperature inversions can significantly increase the levels of eBC and PM and deteriorate local air quality. During temperature inversions the measured mean eBC and PM2.5 mass concentrations in the whole hollow were as high as 4.5±2.6 and 48.0 ± 27.7 µg m−3, respectively, which is comparable to larger European urban centres.

18. Comparing black-carbon- and aerosol-absorption-measuring instruments – a new system using lab-generated soot coated with controlled amounts of secondary organic matterDaniel M. Kalbermatter, Griša Močnik, Luka Drinovec, Bradley Visser, Jannis Röhrbein, Matthias Oscity, Ernest Weingartner, Antti-Pekka Hyvärinen, Konstantina Vasilatou, 2022, original scientific article Abstract: We report on an inter-comparison of black-carbon- and aerosol-absorption-measuring instruments with laboratory-generated soot particles coated with controlled amounts of secondary organic matter (SOM). The aerosol generation setup consisted of a miniCAST 5201 Type BC burner for the generation of soot particles and a new automated oxidation flow reactor based on the micro smog chamber (MSC) for the generation of SOM from the ozonolysis of α-pinene. A series of test aerosols was generated with elemental to total carbon (EC TC) mass fraction ranging from about 90 % down to 10 % and single-scattering albedo (SSA at 637 nm) from almost 0 to about 0.7. A dual-spot Aethalometer AE33, a photoacoustic extinctiometer (PAX, 870 nm), a multi-angle absorption photometer (MAAP), a prototype photoacoustic instrument, and two prototype photo-thermal interferometers (PTAAM-2λ and MSPTI) were exposed to the test aerosols in parallel. Significant deviations in the response of the instruments were observed depending on the amount of secondary organic coating. We believe that the setup and methodology described in this study can easily be standardised and provide a straightforward and reproducible procedure for the inter-comparison and characterisation of both filter-based and in situ black-carbon-measuring (BC-measuring) instruments based on realistic test aerosols.
