Get PDFMagistrsko delo Vpeljevanje readymade-a in destrukcije v konceptualno fotografijo obravnava konceptualno umetnost ter fotografijo tega področja. Delo je razdeljeno na dva dela. Ker je moja glavna tema praktičnega dela prikazati problematiko dirkaškega športa skozi fotografsko instalacijo, prvi del govori o konceptualni umetnosti in dveh ustvarjalnih pristopov, ki sta zanjo značilna. To sta uporaba readymade objektov ter različni postopki uničevanja umetniških del.
Za temo raziskovanja sem si zadal opisati, kakšni procesi spremenijo vsakdanje objekte in dejanja destrukcije v umetniško kreacijo. S tem želim, da bi bralec spoznal, da imajo lahko navadni predmeti ter postopki zažiganja ali brisanja tudi izrazno vrednost, če za njimi stoji konkretna idejna zasnova.
Ker je temeljni medij praktičnega dela magistrskega dela fotografija, se drugi del posveča konceptualni fotografiji, predstavlja njen razvoj od začetka do danes. Skozi primere ustvarjalcev pa se dotika tudi njenih umetniških zasnov.
Po pisnem delu sledi opis praktičnega dela magistrskega dela, in sicer fotografske instalacije z naslovom Accelerato. Ta predstavlja, kako moto-šport vpliva na onesnaževanje okolja skozi štiri sklope, kjer sem fotografije uničeval ali jih tiskal na readymade avto dele.The master\u27s thesis Introducing Readymade and Destruction Into Conceptual Photography deals with conceptual art and the photography of this field. The assignment is divided into two parts. Since my main topic of the practical work is to present the issues of racing sports through a photographic installation, the first part talks about conceptual art and two creative approaches that are characteristic of it. These are the use of readymade objects and various procedures for destroying works of art.
As the topic of my research topic, I set myself to explore the process of transforming everyday objects and acts of destruction into artistic creation. In doing so, I want the reader to realize that ordinary objects and the procedures of burning or erasing can also have expressive value if there is a concrete conceptual design behind them.
Since the fundamental medium of the practical work of the assignment is photography, the second part is dedicated to conceptual photography. It presents its development from the beginning to the present day. It also touches on its artistic concepts through examples of creators.
After the theoretical part, there is a description of the practical work of the master\u27s thesis, a photographic installation entitled Accelerato. Installation represents how motorsports affects environmental pollution, and it consists of four sections where I destroyed photos or printed them on readymade car parts

Isotropy of Cosmic Rays beyond 10[sup]20 eV Favors Their Heavy Mass Composition
No full textWe report an estimation of the injected mass composition of ultrahigh energy cosmic rays (UHECRs) at energies higher than 10 EeV. The composition is inferred from an energy-dependent sky distribution of UHECR events observed by the Telescope Array surface detector by comparing it to the Large Scale Structure of the local Universe. In the case of negligible extragalactic magnetic fields (EGMFs), the results are consistent with a relatively heavy injected composition at E ∼ 10 EeV that becomes lighter up to E ∼ 100 EeV, while the composition at E > 100 EeV is very heavy. The latter is true even in the presence of highest experimentally allowed extragalactic magnetic fields, while the composition at lower energies can be light if a strong EGMF is present. The effect of the uncertainty in the galactic magnetic field on these results is subdominant
Detection and characterization of colloidal silver nanofluids by photothermal techniques
No full textUpdate on full-sky searches for large- and medium-scale anisotropies in the UHECR flux using the Pierre Auger Observatory and the Telescope Array
Get PDFThe flux of ultra-high-energy cosmic rays (UHECRs) is remarkably uniform across all directions in the sky. The only anisotropy detected with a significance greater than 5σ is a large-scale dipolar modulation in right ascension for energies above 8 EeV. To enhance our sensitivity to potential anisotropies, which may be obscured by significant deflections by magnetic fields, two strategies can be employed: (1) focusing on large-scale anisotropies, such as the dipole and quadrupole moments across various energy intervals, which are anticipated to be more resilient to magnetic deflectionsor (2) focusing on the highest energies, where the background from distant sources is more attenuated. The unique aspect of our research is achieving full-sky coverage by combining data for the Pierre Auger Observatory and the Telescope Array, which would not be possible with a single detector array. This comprehensive coverage enables the application of analysis techniques that would otherwise require specific assumptions with partial sky coverage. Accounting for potential systematic effects in energy reconstruction is crucial to avoid spurious north–south anisotropiesthe overlapping sky region observed by both arrays allows us to address this in an entirely data-driven manner. In this contribution, we present the latest results using the largest UHECR dataset collected to date, with events detected until December 2022 at the Pierre Auger Observatory and until May 2024 at the Telescope Array. It is shown that the dipolar modulation is the only anisotropy that is significantly (4.6σ) identified in the angular power spectrum. The hypothesis of correlations with the starburst galaxies is supported at the significance of 4.4σ
The distribution of ultrahigh-energy cosmic rays along the supergalactic plane measured at the Pierre Auger Observatory
Get PDFUltrahigh-energy cosmic rays are known to be mainly of extragalactic origin, and their propagation is limited by energy losses, so their arrival directions are expected to correlate with the large-scale structure of the local Universe. In this work, we investigate the possible presence of intermediate-scale excesses in the flux of the most energetic cosmic rays from the direction of the supergalactic plane region using events with energies above 20 EeV recorded with the surface detector array of the Pierre Auger Observatory up to 2022 December 31, with a total exposure of 135,000 sq. km sr yr. The strongest indication for an excess that we find, with a posttrial significance of 3.1σ, is in the Centaurus region, as in our previous reports, and it extends down to lower energies than previously studied. We do not find any strong hints of excesses from any other region of the supergalactic plane at the same angular scale. In particular, our results do not confirm the reports by the Telescope Array Collaboration of excesses from two regions in the Northern Hemisphere at the edge of the field of view of the Pierre Auger Observatory. With a comparable integrated exposure over these regions, our results there are in good agreement with the expectations from an isotropic distribution

No full textInvestigations of CORSIKA thinning levels suitable for studies of photon-hadron discrimination at ultra-high energies
Get PDFCosmic ray detectors like the 3000 sq. km surface array of the Pierre Auger Observatory are
capable of observing high-energy photons in the range of 10[sup]18 to 10[sup]20 eV if the flux
is sufficiently high.
However, no clear candidates for ultra-high-energy photons have been identified yet, so
simulations must be used to study typical trigger patterns and observables for discriminating photons from hadrons, e.g., with neural networks.
Thinning algorithms are applied to keep the computation time and file sizes in a manageable range since the simulation of ultra-high-energy particle showers is computationally expensive.
In CORSIKA, particles with energies below a certain fraction of the primary energy, the thinning level, are exposed to thinning.
In the case of thinning, only one of the particles emerging from an interaction is tracked.
By assigning a corresponding weight, this particle then represents a number of its siblings.
However, the weights of particles that originate from electromagnetic interactions can be 100 times larger than for hadronic interactions.
In contrast to hadronic showers, where a major part of the signal in a surface detector
is produced by muons, photon showers are almost purely electromagnetic.
Using simulations of photon-induced showers with two different thinning levels, the influence
on different observables used for photon-hadron discrimination is investigated.
Effects deriving from both statistical sampling and detector simulations are considered.
Possible influences on station-level as well as event-level observables are probed.
With this study, we are reassured that the optimal thinning parameters determined for
hadron-induced showers are also sufficient for photon-induced showers
