Provisional security of creditors in cross-border civil and commercial matters
Neža Pogorelčnik Vogrinc, 2020, izvirni znanstveni članek

Opis: Provisional measures can be of utmost importance to creditors especially in relationships with a cross-border element. The Regulation 1215/2012 is the legal source that provides rules regarding the jurisdiction to issue a provisional measure but also offers imperfect provisions regarding the recognition and enforcement of foreign provisional measures issued in other Member States of the European Union. Due to the inadequate regulation, CJEU case law has played an important role, but nevertheless the article finds and opens new questions that have not yet been answered.
Ključne besede: Regulation 44/2001, Regulation 1215/2012, provisional measure, jurisdiction, recognition, enforcement, arbitration clause, real connecting link

Servo pogoni in industrijsko Ethernet omrežje
Luka Bricman, 2019, diplomsko delo

Opis: Diplomsko delo je osredotočeno na uporabo industrijskega Ethernetnega standarda CC–Link za vodenje Mitsubishijevih sistemov s servo pogoni. Namen je bil vzpostaviti in preizkusiti povezave servo pogonov, krmilnikov in HMI-naprav. Za pravilno delovanje laboratorijskega sistema sem moral upoštevati lastnosti in uporabniška navodila za uporabljeno strojno opremo in izdelati uporaben program za testno delovanje, pri tem pa upoštevati pravila avtomatizacijske tehnike. Izdelan je bil testni program za vodenje servo motorja pri določeni hitrosti. Na tem programu smo izvedli tudi meritve časovnih zamikov med ukaznimi in statusnimi signali.

Interoperability between architectural and structural bim software in the case of a mall project
Drilon Rraci, 2017, magistrsko delo

Opis: This master thesis deals with the effect of interoperability between architectural and structural BIM software in the case of a Mall project. The research and most of the work was performed on a BIM model of the Mall project that was modeled using Tekla BIM software. Since there is still a lack of investigations addressing interoperability issues in the structural engineering domain, this thesis pretends to show the collaboration between architectural and structural BIM software, taking into account a real and complex project. A general overview and research regarding building information modeling (BIM) and interoperability issues were done in this project. Various case studies were conducted, where the entire BIM model and partial models of the Mall project were transferred from BIM to FEM software using different data exchange methods. Structural analysis and design in the case of the relevant partial models of the Mall project were performed with the help of Dlubal-Structural Engineering Software for Analysis and Design. Such analyses were made in the structural analysis program RFEM, to investigate if those partial models are imported correctly. The general conclusion based on the used case studies is that data exchange between BIM and FEM software can be useful, but the ease of use depends on both the data exchange method and the way how the relevant model has been created in Tekla BIM software. Referring to these case studies, the most successful data exchange was achieved by using the direct link between BIM and FEM software.

Link prediction on Twitter
Sanda Martinčić-Ipšić, Edvin Močibob, Matjaž Perc, 2017, izvirni znanstveni članek

Opis: With over 300 million active users, Twitter is among the largest online news and social networking services in existence today. Open access to information on Twitter makes it a valuable source of data for research on social interactions, sentiment analysis, content diffusion, link prediction, and the dynamics behind human collective behaviour in general. Here we use Twitter data to construct co-occurrence language networks based on hashtags and based on all the words in tweets, and we use these networks to study link prediction by means of different methods and evaluation metrics. In addition to using five known methods, we propose two effective weighted similarity measures, and we compare the obtained outcomes in dependence on the selected semantic context of topics on Twitter. We find that hashtag networks yield to a large degree equal results as all-word networks, thus supporting the claim that hashtags alone robustly capture the semantic context of tweets, and as such are useful and suitable for studying the content and categorization. We also introduce ranking diagrams as an efficient tool for the comparison of the performance of different link prediction algorithms across multiple datasets. Our research indicates that successful link prediction algorithms work well in correctly foretelling highly probable links even if the information about a network structure is incomplete, and they do so even if the semantic context is rationalized to hashtags.

Link prediction in multiplex online social networks
Mahdi Jalili, Yasin Orouskhani, Milad Asgari, Nazanin Alipourfard, Matjaž Perc, 2017, izvirni znanstveni članek

Opis: Online social networks play a major role in modern societies, and they have shaped the way social relationships evolve. Link prediction in social networks has many potential applications such as recommending new items to users, friendship suggestion and discovering spurious connections. Many real social networks evolve the connections in multiple layers (e.g. multiple social networking platforms). In this article, we study the link prediction problem in multiplex networks. As an example, we consider a multiplex network of Twitter (as a microblogging service) and Foursquare (as a location-based social network). We consider social networks of the same users in these two platforms and develop a meta-path-based algorithm for predicting the links. The connectivity information of the two layers is used to predict the links in Foursquare network. Three classical classifiers (naive Bayes, support vector machines (SVM) and K-nearest neighbour) are used for the classification task. Although the networks are not highly correlated in the layers, our experiments show that including the cross-layer information significantly improves the prediction performance. The SVM classifier results in the best performance with an average accuracy of 89%.

Optimal kinematic design of a link-drive mechanism with prescribed velocity characteristics
Bojan Vohar, Karl Gotlih, Jože Flašker, 2003, kratki znanstveni prispevek

Opis: The paper presents an example of a link-drive mechanism for a deep drawing mechanical press. Because of its characteristics such a drive is much more appropriate than conventional crankshaft or eccentric drive. The existing design of the drive has proved unsatisfactory and does not meet all the demands and constraints, which are ideal for deep drawing process. Optimization of the drive is therefore necessary. The intention is to achieve the required velocity characteristics in a defined area of movement. Firstly, the drive is analyzed and a mathematical model is made and prepared for optimization procedure. The process is time-dependent, so it cannot be used directly in the optimization algorithm. Mathematical model is transformed intoa form suitable for the standard non-linear optimization procedure and then optimization is carried out. The method used is sequential quadratic programming. The final objective of the optimization process is to find such dimensions of link-drive members that the given requirements are satisfied in the best possible manner.

RAZVOJ ROBOTSKIH CELIC ZA IZDELAVO VZGLAVNIKOV
Živko Jeseničnik, 2010, diplomsko delo

Opis: V diplomski nalogi je analizirana robotska celica s transportnim sistemom Flex —Link, ki omogoča transport vzglavnikov na pripravi vzglavnikov za kontinuirano penjenje in na dodelavi z vtikanjem palic in kontrolo proti izpadanju palic iz vzglavnika. Izdelana je bila rešitev, ki omogoča odvzemanje penjenjih vzglavnikov iz stroja za zalivanje z PU maso, prenos vzglavnikov na sistem za transport in nato transportiranje vzglavnikov na delovni postaji vtikanja in kontrole palic in nato naprej na ročno delovno mesto prenosa vzglavnikov na košare visečega transporterja. Pri projektiranju robotske celice smo poizkušali poiskati enostavno rešitev, ki bi zagotovila najbolj optimalne stroške in s tem smiselnost investicije. To nam je na kompletnem delu v celoti uspelo, kajti na spremembah tehnologije izdelave vzglavnikov, se je to zelo hitro pokazalo kot zelo dobra inovativna rešitev. Naloga s svojo vsebino prispeva k projektiranju robotskih celic s kontinuiranim transportom v različnih montažnih procesih sestave in kontrole sestavnih delov.
