Opis: Besides being a fundamental infrastructure for communication, cellular networks are increasingly exploited for positioning via signal fingerprinting.
Here, we focus on cellular signal fingerprinting, where an accurate and comprehensive knowledge of the network is fundamental.
We propose an original multilevel database for cellular networks, which can be automatically updated with new fingerprint measurements and makes it possible to execute a number of meaningful analyses. In particular, it allows one to monitor the distribution of cellular networks over countries, to determine the density of cells in different areas, and to detect inconsistencies in fingerprint observations.

Space weather research with the Pierre Auger ObservatoryMiha Živec
, 2019, magistrsko delo
Opis: Space weather refers to environmental conditions in the interplanetary space and Earth’s
magnetosphere, ionosphere and exosphere and can influence the performance and reliability
of electronics based technological systems. The major role in space weather
changes plays the solar wind, a stream of charged particles (mostly electrons and protons)
with energies of approximately 1 keV, that can cause geomagnetic storms and auroras.
During their entry into the atmosphere, high energy cosmic rays collide with atomic
nuclei of atmospheric gasses. When scattering occurs extensive air showers are created.
Those cascades of secondary particles create flashes of light due to the Cherenkov
effect as well as excite molecules of nitrogen gas in atmosphere, which then glow in
fluorescent light. In order to observe the light created by air showers, it has to be
collected with telescopes. The particles from the cascades that reach ground can be
detected with surface detectors. The Pierre Auger Observatory is the largest observatory
for cosmic ray measurements. It is located in Argentinian pampas covering an area of
3000 km2. It consists of 1660 surface detectors and 27 fluorescence telescopes. For
cosmic rays with energies above few 1017 eV, a precise reconstruction of energy and
direction of primary particle is achievable. Observatory also allows measurement of
flux of incoming particles down to primary energies in ca. 10 GeV - 10 TeV interval, with a median energy ca. 80-90 GeV. This measurement capability is called "scaler"
mode, since the corresponding data consist of scaler counted cascade particles with
deposited energy between 15 and 100 MeV, at the average rate of 2 kHz per individual
For the purpose of this master thesis I compared the data from scaler mode measurements
with measurements of neutron monitors, which are commonly used for space weather
observations. With the correlation received from the comparison, I showed that scaler
mode operation of Pierre Auger observatory can be used to monitor space weather events
such as solar cycle and the decreases in the observed galactic cosmic ray intensity due
to solar wind (Forbush decrease).

Assessment of cortisol and DHEA concentrations in Griffon vulture (Gyps fulvus) feathers to evaluate its allostatic loadGian Nicola Frongia

, 2019, izvirni znanstveni članek
Opis: The use of a non-invasive approach to collect biological samples from natural populations represents a great means of gathering information while avoiding handling animals. Even if corticosterone is the main glucocorticoid investigated in birds, it has been observed a proportional direct link between corticosterone and cortisol concentrations. Dehydroepiandrosterone (DHEA) can be produced by the adrenal cortex and should have prominent antiglucocorticoid properties also in birds. The aim of this study was to verify if there is any difference in the cortisol and DHEA feather concentrations between clinically normal and physiologically compromised Griffon vultures (Gyps fulvus) through the non-invasive approach of collecting moulted feathers without having to pluck them from the bird. The study was carried out using 8 physiologically compromised (PC) Griffons and 9 clinically normal Griffons considered as the control (CTRL) group that were necropsied or from the wildlife rehabilitation centre. Primary and secondary covert feathers were either collected directly from the birds’ cage floors, or, in the case of dead Griffons, they were plucked off the animals. The results, obtained by RIA, revealed that both cortisol (P<0.01) and DHEA (P<0.05) feather concentrations were higher in the PC than in the CTRL group. No difference was observed by comparing the cortisol/DHEA ratio between the two evaluated groups (P=0.15). Pearson’s correlation coefficients showed no correlation between feather hormone concentrations in the PC group (r=0.01, P=0.96) while a positive correlation in the CTRL group (r=0.65, P=0.006) was observed. In conclusion, our study reveals that moulted feathers can be a non-invasive and an interesting tool to evaluate the allostatic load of wild birds and they allowed to better understand the relationship between hormones of the hypothalamic–pituitary–adrenal axis and the physiological status of the birds.

, 2019, objavljeni povzetek znanstvenega prispevka na konferenci
Opis: Qualitative behaviour assessment (QBA, from the AWIN welfare assessment protocol for sheep) relies on the ability of humans to integrate perceived details of behaviour into descriptors with emotional connotation that can be scaled and added to other quantitative indicators. The complete AWIN protocol was performed in 14 groups (6
extensive, 2 semi-intensive and 6 intensive rearing system) of 15 young lambs (2 months of age) participating in the EcoLamb project (ERA-Net SusAn funded), which aims to holistically evaluate lamb production sustainability (meat quality, ecological footprint and animal welfare). Data on QBA (items were being scaled from 0 –absence- to
10 -all the animals fully expressed the evaluated item-), familiar approach and fleece quality tests were subjected to descriptive statistics analyses and showed herein. Extensively reared lambs scored higher in descriptors such as aggressive, defensive, physically uncomfortable or apathetic, whereas intensively reared lambs showed higher values in descriptors such as agitated and fearful but also in other as active, sociable, vigorous, subdued, calm,
inquisitive and assertive. Semi-intensively reared lambs scored in between. All the animals ruminated to some extent (when observed), the quality of the fleece was always acceptable and no stereotypes were recorded. Minor lameness problems were observed in one extensive farm. Regarding familiar approach, all animals (except in one
farm) voluntarily approached to human, despite a flight distance of 2 to 4 m was observed at the beginning. Although animal welfare is a real complex matter to be assessed, do animals from different rearing systems express different degree of positive emotional state?

Razvoj in trženje mobilne aplikacije za pomoč pri izbiri nosilke za dojenčkaMojca Drobič
, 2019, diplomsko delo
Opis: Nosilke za nošenje dojenčkov so postale svetovni trend, čemur sledi bogata izbira modelov nosilk različnih proizvajalcev. Namen razvoja in trženja mobilne aplikacije za pomoč pri izbiri nosilke za dojenčka je izobraževanje potrošnikov (mladih staršev) o merilih, ki so ključni pri izbiri nosilke. Cilj naloge je razviti mobilno aplikacijo, ki vodi uporabnika pri izbiri nosilke za dojenčka, z omejevanjem nabora nosilk na tiste, ki bi jim lahko ustrezale na podlagi starosti dojenčka. Mobilna aplikacija na osnovi vhodnih podatkov ponudi za vsako starostno skupino dva nabora ergonomskih nosilk, v enem naboru so nosilke, ki so uvrščene v nabor na podlagi lastnosti, ki jih predpiše proizvajalec, v drugem naboru pa so nosilke, ki so jih uvrstile na seznam svetovalke spletne trgovine mojŠkratek, na podlagi preizkušanja nosilk z več sto dojenčki.
V diplomski nalogi je opisana podporna mobilna tehnologija, s poudarkom na razvoju mobilnih aplikacij s pomočjo agilne skram (angl. Scrum) metodologije. Sledi navedba dejstev o ergonomskem nošenju in ergonomskih pripomočkih za nošenje dojenčkov ter predstavitev mobilne aplikacije, ki je bila razvita na podlagi zahtev, pridobljenih z anketiranjem staršev. Predstavili smo tudi rezultate anket, s katerimi smo ocenili uspešnost mobilne aplikacije po preizkusnem obdobju 30 dni. Izkazalo se je, da je mobilna aplikacija učinkovito izobraževalno sredstvo, vendar ne more nadomestiti fizičnega pristopa usposobljene osebe, za oceno ustrezne ergonomske podpore dojenčka v nosilki.
Za vstop mobilne aplikacije na trg smo pripravili poslovni načrt, v katerem smo opisali predvideno poslovno pot mobilne aplikacije.

HOLISTIC GEOMORPHOLOGICAL SPATIAL ANALYSIS OF KARST ON KRK ISLANDEla Šegina
, 2019, doktorska disertacija
Opis: The intriguing spatial variability of surface features on Krk Island has stimulated the research of this karst area located in the coastal zone of the Dinaric karst in Croatia. Field inspection, ortho-rectified aerial photos (0.5m resolution) and a topographic map (1:5,000) were used for the detection and delineation of detectable karst surface features appearing on the island with the area of 405.5 km². This method resulted in the identification of several yet undefined types of surface features occurring on karst, requiring the revision of the existing classification and re-establishment of a new classification system compatible with the particular field reality. Several morphologic and distributive parameters that had been calculated for each re-classified type of surface feature provided insight into the surface features elementary characteristics, their spatial variability and the correlation to the other types of surface features and to the recent karst relief. This analysis based on a large, accurate dataset, contributed to the general knowledge on karstic surface features, the conditions of surface features in Dinaric karst and to the understanding of the karst surface evolution on Krk Island.

Quality Assured Across Borders of Disciplines and CulturesPeter Purg
, 2019, objavljeni povzetek znanstvenega prispevka na konferenci (vabljeno predavanje)
Opis: Abstract (full):
Within the international master study programme of Media Arts and Practices (MAP) the University of Nova Gorica School of Arts is currently developing an interdisciplinary module in Art, Science and Technology (MAST) within a diverse partnership of two further universities and three NGOs. Both curriculum development projects were funded by the European Commission for their progressive, even disruptive character. If MAP (2011-2014), developed within the ADRIART.net project, was to join four countries as well as several artistic and media production fields creating a new partnership model and a contemporary employment profile, MAST (2018-2020) now seeks to root the art-thinking paradigm deep into the innovation process outside university. In order to reinvent better and meaningful futures for the society at large the dominance of the technological and the scientific approach is to be balanced out by the artistic openness and radical difference. This in turn mirrors the structure of the MAST curriculum – not only that its outcomes are unprecedented and tuned onto most progressive priorities of the Europen Union. The syllabus reminds of the innovation process itself, building a new module-specific graduate profile of an “innovation catalyst’.
The abovementioned two cases will be interpreted on the background of ‘The Standards and Guidelines for Quality Assurance in the European Higher Education Area’ (ESG) as the primary setting of their development and implementation, while the ‘internal’ quality aspect shall be prioritized. The discussion will predominantly refer to the design and approval of programmes, but also present some novel solutions in student-centered learning, teaching and assessment. After touching upon a relevant recognition issue, the public impact and meaning of such programmes will be considered more broadly.
As far as the design and approval of programmes (ESG 1.2) are concerned, the Guidelines point out that curricula should be designed „in line with the institutional strategy“ which often proves a paradox – a new academic programme development may instigate radical institutional change from the bottom-up, such that is unlikely to occur through the conventional top-down approach. The MAP project involved four university partners, of which two accredited the master programme fully as such (Croatia and Slovenia) and two participated therein merely with partnership modules. While the Slovenian partner gradually modified its strategic priorities as a (fairly small) art school throughout the project's three years, the bigger Croatian national art academy would let the MAP programme remain insulated from other programmes, preventing the curricular innovations and new teaching and learning methods from spreading to other programmes. This eventually led to inter-institutional conflicts and a closure of the programme in 2018 after three years of its running. Even if all invlved universities „involved students and other stakeholders in the work“ and the MAP programme contained „well-structured placement opportunities“ (ESG 1.2), its sustainability was evaluated low also in the case of the Italian and Austrian partners, since most of the MAP curricular structures eventually proved too open and progressive for their traditional acdemic environments. The Graz Technical University (Austria) returned in the MAST project again to enter a new, more contemporary alliance, founded on their bilateral continuity with the University of Nova Gorica, and their strategic priority of developing interdisiplinary programmes. The latter has in 2014 also established and continues to lead a South-Eastern-Europe wide CEEPUS network of ten art academies named ADRIART.CE (Belgrade, Budapest, Graz, Nova Gorica, Krakow, Rijeka, Split, Sarajevo, Belgrade, Skopje, Sofia), three of which presented its core that developed from the MAP partnership (www.ADRIART.net/ce). Besides Nova Gorica and Graz, the MAST partnership involves one further university (Madeira University, Portugal) and three NGOs (the renowned Kapelica Gallery from Slovenia, the Croatian Cultural Allience and the Europe-wide network Culture Action Europe).
The ESG standard 1.3 on student-centred learning, teaching and assessment suggests that the programme delivery should „encourage students to take an active role in creating the learning process, and that the assessment of students reflects this approach.“ The MAP programme manifests this approach in several novums such as the 'Progress Track' module, where students critically peer-reflect on their academic progress along three semesters, or the 'Studio' module that brings into the programme external art (and later in MAST also science and/or technology) practitioners. It also treats contemporary topical issues that relate to the European topics such as e.g. 'The Future of Work' as well as to the profile of the cohort, their course selections and career orientation. A continuous 'Carrier Module' (MAST being one of them, others are Film, Animation, New Media, Photography and Contemporary Art Practice) in the MAP programme supports the student's „flexible learning path“ along three semesters of gradual academic progression: After exploring the chosen realm, and then defining own topical interest and method, the student focuses on her or his area of artistic (or interdisciplinary) investigation, in order to complete the Master Thesis (that includes a theoretical thesis and a practical project) in the fourth semester, all to encourage „a sense of autonomy in the learner, while ensuring adequate guidance and support from the teacher“. In the case of MAST the students shall each year be faced with the semester-long 'Challenge' course that is to keep them deeply involved in a real-life innovation process brought in from NGOs or companies, along with their expert mentors, or evaluators (in assessment committees, programme boards etc).
Both MAP and MAST curriculum development projects focussed importantly on the issue of „fair recognition of higher education qualifications, periods of study and prior learning, including the recognition of non-formal and informal learning“ (ESG 1.4). This was to not only support but also promote mobility of staff and especially students, since both curricular structures instigate international as well as inter-sectoral collaboration: if the academic experience of students and their career prospects is to be advanced, a dynamc flux and interaction of students, (external) mentors and (university) teachers needs to be preserved at both entry and exit points to the programme (or module). Only this way the positive public impact and meaning of such programmes (ESG 1.8) can be kept transparent – not only to be accounted for, but also actively steered towards actual social and economic relevance! Study programmes that matter to all stakeholders – the students, the universities and the employers, including a broader public, need to be kept open for manifold talents and apply progressive interdisciplinary teaching and learning methods, attracting experts and tackling real-life challenges across disciplinary sectors, and national borders.
