This paper is intended to give an overview of the experiments to evaluate the cognitive load of the officer on watch (OOW) during a collision avoidance maneuver in a full-mission simulator. The main goal is to investigate the possibilities of recording the biometric parameters of an OOW during a simulated collision avoidance maneuver. Potentially dangerous navigation errors known as human erroneous action (HEA) are induced by excessive cognitive load. Despite modern navigational aids on the ship’s bridge, investigators of maritime incidents typically link the reason for incidents at sea with human factors, including high cognitive load. During the experimental tasks on the bridge, the biometric parameters of the OOW are recorded. Statistical tools are used to visualize the data and evaluate the cognitive load of the OOW. Biometric peaks of the OOW typically occur either during the collision avoidance maneuver or when the OOW has been exposed to disturbing factors that increase reaction time and cause potentially dangerous navigation. Assessing the cognitive load of OOWs in the simulator is challenging for several reasons: e.g., the environmental conditions of the simulator, the type of task to be simulated, and even the type of sensor used. After careful study of the available literature, an original experimental design using non-invasive biometric sensors is proposed.

V okviru diplomskega dela je bilo izvedeno konstruiranje in preračun A-rok Formula Student dirkalnika ter njihova izdelava, v kar spada tudi določitev kinematike podvozja. V začetku naloge so podane informacije o projektu Formula Student in obrazložen pravilnik. Nato je bila podana ustrezna teoretična podlaga parametrov podvozja, ki ji sledi razvoj na podlagi razumevanja teorije teh parametrov. Sledi konstruiranje in izbira materiala za optimiziranje mase ter trdnostni preračun za preverbo nosilnosti konstrukcije. Ugotovili smo, da smo lahko z boljšo pozicijo vpetja A-rok izboljšali vozne lastnosti dirkalnika. Na koncu še omenimo izdelavo in preizkušanje A-rok. Within the framework of the diploma thesis, the design and strength analysis of the double wishbone suspension of the Formula Student racing car was performed, including the determination of the kinematics of the suspension. The wishbone suspension was also manufactured. At the beginning of the assignment, information about the Formula Student project and explained rules are provided. An appropriate theoretical basis for the suspension parameters was then given, followed by development based on an understanding of the theory of these parameters. This is followed by the design and selection of material to optimize the mass and a strength analysis to check the load-bearing capacity of the structure. We found that with a better double wishbone mounting position, we were able to improve the driving performance of the race car. Finally, the manufacturing process and testing of double wishbone is discussed.

In this chapter, we review and discuss the state of the art on sentiment analysis in social streams—such as web forums, microblogging systems, and social networks, aiming to clarify how user opinions, affective states, and intended emo tional effects are extracted from user generated content, how they are modeled, and howthey could be finally exploited.We explainwhy sentiment analysistasks aremore difficult for social streams than for other textual sources, and entail going beyond classic text-based opinion mining techniques. We show, for example, that social streams may use vocabularies and expressions that exist outside the mainstream of standard, formal languages, and may reflect complex dynamics in the opinions and sentiments expressed by individuals and communities.

This article reviews selected mechanisms by which modern communications technologies shape media. The main thesis is that to a great (if not undue) extent what shapes electronic media are the nature of technological development, functional demands as seen from a technological expert%s point of view, and project administration. Media constitute a complex phenomenon that to a great degree appears to be shaped by technology, and not the reverse. Our hypothesis is that technological progress influenced the understanding or organization of the time, rhythm, and speed with which authors and technology shape information and by which the latter is broadcast in time and space. The roles of authors, editors, media proprietors, and the legal framework have changed, as have related ethical questions. We depict the influence of communications technology on media through the development of leading technological developments over recent decades. We consider the internet, e-books, e-periodicals, social networks, blogs (web diaries), personalizing and contextualizing mechanisms, and use of social signals in web communications. It is not possible here to compile a comprehensive list of advancements. We conclude the paper with a discussion of developments expected in the near future, mainly mechanized social intelligence and its contextual awareness, which will greatly influence the shape of future media. Razprava obravnava izbrane mehanizme, preko katerih moderne komunikacijske tehnologije sooblikujejo medije. Osnovna teza je, da specifike tehnološkega razvoja elektronske medije oblikujejo v (pre)veliki meri. Mediji so kompleksen pojav in zdi se, da jih v veliki meri oblikuje tehnologija, manjši pa je vpliv v obratni smeri, tj. prispevek in udeležba uporabnikov v procesu sooblikovanja čim boljše uporabniške izkušnje bralcev, enostavnosti uporabe itd. Moja hipoteza je, da je tehnološki napredek vplival na dojemanje in organizacijo časa, ritma, hitrosti, s katerimi avtorji in tehnologija oblikujejo informacije in s katerimi se te razširjajo v času in prostoru. Spremenila se je vloga avtorjev, urednikov, lastnikov medijev, pravne ureditve in s tem povezana etična vprašanja. Vpliv komunikacijske tehnologije na medije prikažemo skozi razvoj glavnih tehnoloških inovacij v zadnjih desetletjih. Obravnavani so medmrežje in splet, e-knjiga, e-časopisi, socialna omrežja, blogi (spletni dnevniki), mehanizmi personalizacije in kontekstualizacije ter uporaba socialnih signalov v spletni komunikaciji. Popolnega seznama storitev ni mogoče sestaviti. Zaključujemo s premislekom o vplivih obravnavanih medijskih tehnologij in sklepamo o razvoju v bližnji prihodnosti. Očitno bo razvoj socialne inteligence strojev z zavedanjem konteksta močno vplival na podobo medijev.
