2. Exploring the role of advertising in the context of tourist-destination congruityTina Šegota, 2023, izvirni znanstveni članek Opis: Tourists are flooded with advertising messages, including destination-attribute-based or user-imagery-based pictures, to persuade them to visit the destination. While research emphasizes destination choice to result from tourist-destination congruity, examining the influence different pictures have on tourist decision-making is of increasing interest. Therefore, this study sought to investigate the efficacy of destination-attribute-based versus user-imagery-based ad stimuli to influence the tourist-destination congruity and predict a person’s likelihood of choosing the destination. Results from a quantitative study of 496 young Slovenians show that a higher degree of ideal and ideal social tourist-destination congruence would lower one’s perceived purchase risk and yield positive attitudes toward the ad with a destination-attribute-based picture as opposed to the ad with a user-imagery-based picture. Implications for destination marketing are discussed, such as evaluating a typical destination visitor when one is included in the advertising and when one is not.

3. Development of visualization software for electrical machines' windings : master thesisLea Novak, 2021, magistrsko delo Opis: Windings are the key to the proper operation of electrical machines. Different methods for windings visualization are being studied. In this context, the thesis presents the development of calculation and visualization software for distributed and concentrated windings. The software was created in a joint project between Elin Motoren GmbH and the Faculty of Electrical engineering and Computer Science. The project consists of 3 MSs. The focus of the first two MSs are distributed windings (lap and wave windings), while the third MS describes concentrated windings for PM motors. All three MSs provide analytical calculation of windings and visualization of winding layout. In MS 3, the Cros' method for visualization of concentrated windings is described. The influence of a combination of the number of poles and slots in PM machines windings on noise, vibrations and torque is also studied.

4. Visualization of alpha-beta game tree search : magistrsko deloEmilija Taseva, 2019, diplomsko delo Opis: Algorithms make up a crucial part of computer science studies. Learning and understanding new algorithms can be quite interesting, but also hard and complex, especially for students. Visualization can significantly help with the understanding of the dynamic behaviour of algorithms by visually displaying each step of the algorithm, its purpose and how it changes the data. Besides faster and more efficient learning, the better understanding can also lead to potential algorithm improvements in the future. The goal of this thesis is visualization of the alpha-beta tree search algorithm for determining the next optimal move in a two-player, zero-sum, complete information game. The algorithm is visualized using two games, Tic-Tac-Toe and Othello. The algorithm operation can also be demonstrated using a custom tree with parameters chosen by the user.

5. Developing spatial visualization with 3D modelingAndrej Šafhalter, Srečko Glodež, Karin Bakračevič, 2012, izvirni znanstveni članek Opis: The research was carried out in 20 11 among 22 pupils from 14-15 years old. The purpose of the pilot study was to determine the influence of 3D modeling on the spatial visualization of pupils, as well as the gender difference in the spatial visualization of the tested pupils and the progress of this visualization in individual genders. ln addition, it tried to determine whether the sensory style of the pupils, visual. auditory or kinesthetic, influences spatial perception and the development of spatial visualization. Pupils were divided into two groups, the test group and the control group. Pupils in the test group attended a 3D modeling extra-curricular activity for twelve teaching hours in the second evaluation period of the 2010/2011 school year. Spatial visualization was determined with a modified spatial visualization test. namely before the extra-curricular activity and afterwards. The modified test consisted of different spatial visualization tests: PSVT: R, MeT, MRT, DAT: SR. and tests of rotation within a plane. For 3D modeling exercises pupils used the open-source software Google SketchUp. None of the tested pupils have encountered the mentioned software before. After a second testing, the test group showed greater progress in solving spatial visualization tasks in comparison with the control group, while gender differences were minimal. The results of the spatial visualization test were also compared with the sensory style of pupils, which was filled out by all the pupils included in the study. ln the 2011/2012 school year a broader study is underway, involvlng almost two hundred pupils of various elementary schools in Slovenia.

6. Developing spatial ability using 3D modeling in lower secondary schoolAndrej Šafhalter, Srečko Glodež, Boris Aberšek, Karin Bakračevič, 2014, izvirni znanstveni članek Opis: In recent years 3D modeling has been increasingly utilized during product design in lower secondary schools as well. Its greatest advantage over classical technical drawing and 2D drawing software lies in the fact students are able to observe the object they are designing from all the viewpoints of a virtual three-dimensional space. Since thinking and visualization in the process of object design also appear in three dimensions, the mental manipulation and guesswork required from students in order to add another dimension to an object pictured on a level plane are no longer necessary. Additionally, 3D modeling has a range of contributions to the cognitive development of children, which was also the subject of this research. The central question raised was whether students are able to improve their spatial ability by using modeling tools. The research included 196 students aged between 11-15 years, of which 95 were placed in the experimental group and 101 in the control group. Spatial ability was measured using pre-test and post-test.

7. Impact of nanoparticles on nematic ordering in square wellsMitja Slavinec, Eva Klemenčič, Milan Ambrožič, Marjan Krašna, 2015, izvirni znanstveni članek Opis: Nematic liquid crystalline structures within square wells are studied numerically using both Lebwohl-Lasher lattice semimicroscopic and the Landau-de Gennes mesoscopic approach. At lateral boundary wall strong planar anchoring is enforced. The cell thickness h along the z Cartesian coordinate is assumed to be smaller than the characteristic square well size R. Using semimicroscopic modelling we restrict to effectively two-dimensional systems which we study in terms of the tensor nematic order parameter. We consider impact of appropriate nanoparticles (NPs) on nematic configuration for cases where R becomes comparable to the biaxial order parameter correlation length. In this case a star-like order reconstruction biaxial profile could be formed in absence of NPs. We demonstrate existence of a rich variety of different nematic structures, including topological defects, which are enabled by presence of appropriate NPs.

9. Analysis of noise sources produced by faulty small gear unitsAleš Belšak, Jurij Prezelj, 2007, izvirni znanstveni članek Opis: Noise source vizualization represents an important tool in the field of technical acoustics. There are many different techniques of noise source visualization. Most of them, however, are intended for a specific noise source in a specific type of acoustic environment. Consequently, a certain visualization method can be used only for certain types of noise sources in a specific acoustic environment and in a restricted frequency area. This paper presents a new visualization method of complex noise sources on the basis of the use of an acoustic camera. A new algorithm has been used, which makes it possible to visualize all types of different complex noise sources. Monopole, dipole or quadropole noise sources can be observed simultaneously. It is possible to track a moving noise source by means of an acoustic camera. In addition to that it is possible to observe various transient acoustical phenomena. Through the use in diagnostics, it is possible to define, by means of noise, the condition of mechanical systems at an advance level.
