Zaključna naloga obravnava uporabo 3D tiskalnika Ultimaker 3 za tiskanje preizkušancev po metodi ciljnega nalaganja (FDM). Preizkušanci se med seboj razlikujejo po stopnji zapolnitve, notranji strukturi in legi na delovni mizi. Preizkušance smo tiskali za Charpyjev udarni preizkus in tritočkovni upogibni preizkus. Rezultate teh preizkusov smo ovrednotili in jih na koncu še primerjali z enakimi preizkušanci natisnjenih na 3D tiskalniku Ultimaker 2. Ugotovili smo, da imajo vzorci, natisnjeni z Ultimaker 3, boljše mehanske lastnosti in so bolj konsistentni. This paper focuses on production and testing of samples made with an Ultimaker 3 3D printer, using the focused deposition modelling (FDM) process. Main printing parameters of produced samples are infill density, infill pattern and position on build plate. The samples were subjected to a Charpy impact test and three point flexural test. The test results were evaluatated and compered to those of samples produced by an older Ultimaker 2 printer using the same parameter values. The comparison showed that samples produced by the Ultimaker 3 have better mechanical properties and are more consistent.

The subject of the article is the concept of information asymmetry, which currently belongs among highly discussed themes in economics. In the article, we deal with the basic concepts, which play an important role in the overall perspective on the given issue. One of them is moral hazard, which is a fundamental consequence of information asymmetry. The market subjects or individual people often misuse their superior informational capabilities for their own use, but at the same time they inadvertently contribute to the inefficiency of the specific market, which can lead to extensive market failure. Other important consequences include so-called adverse selection, which results in the gradual displacement of good products by inferior ones. The occurrence of adverse selection in the specific market then results in pressure to reduce prices. In particular, the article analyses the current state of knowledge in the area of information economics, on the basis of previously published articles. We also deal with the effect of modern technology on the economic mechanism and information asymmetry. One of them is the internet, which plays a key role in the transmission of information. The aim of the article is to perform an analysis of the current state of knowledge in the area of information asymmetry on the basis of relevant published articles, and thus create a comprehensive and compact perspective on the given issue. An important section is the analysis of the possible impact of modern technology on information asymmetry, where own conclusions are drawn on the basis of findings by various authors.

Diplomsko delo zajema statično analizo objekta, dimenzioniranje konstrukcijskih elementov, bistvenih spojev ter pravilna izbira temeljenja dvoetažne jeklene hale, tlorisa 30 x 15 m, višine 9,0 m oziroma višine 9,35 m v slemenu. Objekt je namenjen industrijski rabi in je sestavljen iz vroče valjanih profilov HEA in HEB, jekla kakovosti S 355. Projektiranje je bilo izvršeno v skladu z evropskimi predpisi Evrokod. In sicer so obtežbe upoštevane po SIST EN 1991:2004, potresna obtežba po SIST EN 1998:2006, dimenzioniranje jeklenih profilov po SIST EN 1993-1-1:2005 ter dimenzioniranje spojev po SIST EN 1993-1-8:2005. The diploma thesis contains static analysis, dimensioning of structural elements, their joints and fundaments of a two-story steel building 30 x 15 m with a height of 9 m or 9,35 m height at the ridge. The structure is designed for industrial use, where hot rolled structural steel members HEA and HEB of S 355 steel were used. The designing process is performed in accordance with European standards Eurocode. The following standards were used: SIST EN 1991:2004 for actions on structures, SIST EN 1998:2006 for earthquake resistance, SIST EN 1993-1-1:2005 for designing of steel members, and SIST EN 1993-1-8:2005 for designing of joints.

The workshop in Copenhagen provided an opportunity to study relevance and potential of computable geospatial model for provision of geographic data by national agencies. This meant to observe and analyse opportunities for delivering functional content - opportunities for delivering geospatial data associated with functionality. The functionality may provide analytical functions, visualisation capabilities, or behaviour ensuring for example authentication, transformation to a different format, different coordinate system, or encryption for transferred geo-data. In short the question is: does, for these agencies, exist any practical reason why to consider use of computable model for their data products?

Geospatial modelling revolves around the structures of data and the semantics of these structures. This is enough in simple cases, but becomes insufficient when the best structure and semantics is hard to find or the solution is too heterogeneous to fix and reuse. Field-based and objects-based geospatial models of- ten share common GIS data structures interchange- ably, but their all possible meanings are too many to define in an immutable manner. Less studied approach to geospatial modelling is using mutable structural properties and their semantic interpretation. This work shows that the functional aspect of geospatial models is just as important as the structural and semantic aspects. It also shows that semantic and even structural properties may change when functionality is integral part of the data model, and not exclusively separated at software implementation level. The paper uses this modelling paradigm to address the divide caused by field-based and object-based data models, and other challenges regarding synergy of geospatial systems that need to use both types of data models.

In this study, an optimization of supersonic air-to-air ejector is carried out by a recently developed single-objective genetic algorithm based on adaption of sequence of individuals. Adaptation of sequence is based on Shape-based distance of individuals and embedded micro-genetic algorithm. The optimal sequence found defines the succession of CFD-aimed objective calculation within each generation of regular micro-genetic algorithm. A spring-based deformation mutates the computational grid starting the initial individualvia adapted population in the optimized sequence. Selection of a generation initial individual is knowledge-based. A direct comparison of the newly defined and standard micro-genetic algorithm is carried out for supersonic air-to-air ejector. The only objective is to minimize the loose of total stagnation pressure in the ejector. The result is that sequence-adopted micro-genetic algorithm can provide comparative results to standard algorithm but in significantly lower number of overall CFD iteration steps.
