Exploiting image quality measure for automatic trajectory generation in robot-aided visual quality inspection
Atae Jafari-Tabrizi, Dieter P. Gruber, Andrej Gams, 2024, izvirni znanstveni članek

Povzetek: Currently, the standard method of programming industrial robots is to perform it manually, which is cumbersome and time-consuming. Thus, it can be a burden for the flexibility of inspection systems when a new component with a different design needs to be inspected. Therefore, developing a way to automate the task of generating a robotic trajectory offers a substantial improvement in the field of automated manufacturing and quality inspection. This paper proposes and evaluates a methodology for automatizing the process of scanning a 3D surface for the purpose of quality inspection using only visual feedback. The paper is divided into three sub-tasks in the same general setting: (1) autonomously finding the optimal distance of the camera on the robot’s end-effector from the surface, (2) autonomously generating a trajectory to scan an unknown surface, and (3) autonomous localization and scan of a surface with a known shape, but with an unknown position. The novelty of this work lies in the application that only uses visual feedback, through the image focus measure, for determination and optimization of the motion. This reduces the complexity and the cost of such a setup. The methods developed have been tested in simulation and in real-world experiments and it was possible to obtain a precision in the optimal pose of the robot under 1 mm in translational, and 0.1° in angular directions. It took less than 50 iterations to generate a trajectory for scanning an unknown free-form surface. Finally, with less than 30 iterations during the experiments it was possible to localize the position of the surface. Overall, the results of the proposed methodologies show that they can bring substantial improvement to the task of automatic motion generation for visual quality inspection.

Response of beech and fir to different light intensities along the Carpathian and Dinaric Mountains
Matjaž Čater, Pia Caroline Adamič, Eva Dařenová, 2024, izvirni znanstveni članek

Povzetek: Predicting global change mitigations based on environmental variables, like temperature and water availability, although yielding insightful hypothesis still lacks the integration of environmental responses. Physiological limits should be assessed to obtain a complete representation of a species’ fundamental niche. Detailed ecophysiological studies on the response of trees along the latitudinal gradient are rare. They could shed light on the behaviour under different light intensities and other studied traits. The forests of the Dinaric Mountains and the Carpathians represent the largest contiguous forest complexes in south-eastern Europe. In uneven-aged Carpathian (8 plots) and Dinaric Mountain (11 plots) forests, net assimilation (Amax) and maximum quantum yield (Φ) were measured for beech and fir in three predefined light intensity categories according to the indirect site factor (ISF%) obtained by the analysis of hemispherical photographs in managed and old growth forests, all located above 800 m a.s.l. The measurements were carried out under fixed environmental conditions in each light category per plot for three consecutive years. Data from the last 50-year average period from the CRU TS 4.01 dataset were used for the comparison between Amax, Φ, and climate. The highest Φ for beech were observed in the central part of the Dinaric Mountains and in the south westernmost and northwesternmost part of the Carpathians for both beech and fir, while they were highest for fir in the Dinaric Mountains in the northwesternmost part of the study area. The Φ-value of beech decreased in both complexes with increasing mean annual temperature and was highest in the open landscape. For fir in the Carpathians, Φ decreased with increasing mean annual temperature, while in the Dinaric Mountains it increased with higher temperature and showed a more scattered response compared to the Carpathians. Short-term ecophysiological responses of beech and fir were consistent to long-term radial growth observations observed on same locations. The results may provide a basis and an indication of the future response of two tree species in their biogeographical range to climate change in terms of competitiveness, existence and consequently forest management decisions.

Building competences for researchers working towards ocean sustainability
Jerneja Penca, Andrea Barbanti, Christopher Cvitanovic, Amel Hamza-Chaffai, Ahmed Elshazly, Jean-Baptiste Jouffray, Nezha Mejjad, Melita Mokos, 2024, izvirni znanstveni članek

Povzetek: The challenges of achieving just, equitable and sustainable ocean futures require a new type of transdisciplinary and action-oriented science that integrates across disciplines and knowledge systems. Scientists and researchers in academia, industry or government, who contribute to knowledge creation, innovation, and policy development for the ocean, must be empowered with a fresh set of competences. This paper maps the knowledge, skills, and attitudes required to enable such a shift. The proposed skillset serves as a foundation for the design and operationalisation of modern training for ocean sustainability and is envisaged to be used by researchers both individually and in teams. It also highlights the potential for career diversification beyond the traditional ’blue jobs’ legitimated by existing sectors. To ensure the short-term practical implementation of the competence framework, self-awareness and self-reflection are encouraged among learners and teachers, along with pragmatic actions to overcome barriers to transdisciplinarity. For long-term impact, system interventions will be necessary to improve organisations’ readiness to absorb and valorise researchers trained in this new framework. This will require re-training the current pedagogical workforce as well as reframing existing knowledge systems and incentives.

Starostniki v statusih animarum župnije Zgonik v dolgem 19. stoletju
Vojko Pavlin, 2024, izvirni znanstveni članek

Povzetek: Župnija Zgonik je najjužnejši izrastek goriške nadškofije v širšem kraškem zaledju tržaškega mesta. Prispevek obravnava demografske značilnosti starostnikov te župnije v dolgem 19. stoletju na osnovi treh statusov animarum. Delež starejših se je gibal okoli desetih odstotkov celotne populacije in je le polagoma naraščal, pretežno zaradi naraščanja števila starostnikov v šestdesetih letih starosti. Daleč največ starostnikov je umiralo »zaradi starosti«, pri čemer se je delež tega vzroka smrti na začetku 20. stoletja celo zopet povečal.

Isotropy groups of the action of orthogonal $^\ast$congruence on Hermitian matrices
Tadej Starčič, 2024, izvirni znanstveni članek

Povzetek: We present a procedure which enables the computation and the description of structures of isotropy subgroups of the group of complex orthogonal matrices with respect to the action of $^\ast$congruence on Hermitian matrices. A key ingredient in our proof is an algorithm giving solutions of a certain rectangular block (complex-alternating) upper triangular Toeplitz matrix equation.

On structures of normal forms of complex points of small ${\mathcal C}^2$-perturbations of real $4$-manifolds embedded in a complex $3$-manifold
Tadej Starčič, 2024, izvirni znanstveni članek

Povzetek: We extend our previous result on the behaviour of the quadratic part of a complex points of a small ${\mathcal C}^2$-perturbation of a real $4$-manifold embedded in a complex $3$-manifold. We describe the change of the structure of the quadratic normal form of a complex point. It is an immediate consequence of a theorem clarifying how small perturbations can change the bundle of a pair of one arbitrary and one symmetric $2 \times 2$ matrix with respect to an action of a certain linear group.

Jugoslavija i ambivalentnost ekonomske saradnje Jug-Jug u sedamdesetim i osamdesetim godinama
Jure Ramšak, 2024, izvirni znanstveni članek

Povzetek: Na vrhuncu napora zemalja u razvoju da uspostave Novi međunarodni ekonomski poredak, Jugoslavija je, kao jedna od vodećih članica Pokreta nesvrstanih i Grupe 77 zemalja u razvoju (G-77), nastojala da dokaže da je moguće uspostaviti novi obrazac odnosa između industrijski razvijenih zemalja, kojima je delimično i sama pripadala i saveznika iz ove koalicije, čije su ekonomske baze još uvek bile u fazi izgradnje. U skladu sa određenim dominantnim grupama unutar UN-a, jugoslovenska teorija razvoja spajala je marksistička sa neoklasičnim ekonomskim shvatanjima u ambiciozan program globalne reforme koja je odstupala od stavova kapitalističkih i socijalističkih velesila. Ipak, u isto vreme, ova vizija globalizacije morala je da se nosi sa ideološkim, geopolitičkim i ekonomskim uticajem novonastale neoliberalne revolucije, koja je početkom osamdesetih počela bitno sužavati prostor za manevrisanje. Pored programskih načela sadržanih u zvaničnim dokumentima, ovaj rad prati i konkretne oblike jugoslovenske bilateralne ekonomske saradnje sa pojedinim afričkim zemljama.
