In dieser Arbeit wird mittels verschiedener Methoden die Datenfusion von Unfallszenarien untersucht. Ausgangspunkt sind zwei Datensätze aus der Datenbank der polizeilichen Unfallstatistik. Im Empfängerdatensatz wird das spezifische Attribut „Unfalltyp“ entfernt, welches mithilfe des Spenderdatensatzes ergänzt werden soll. Ziel ist das Erstellen einer einheitlichen Datenbasis, deren Qualität mittels geeigneter ausgewählter Metriken bewertet wird. Als Methode der Datenfusion wird zum einen das Distance-Hot-Deck-Verfahren verwendet. Zum anderen werden vier aussichtsreiche Machine Learning Verfahren auf Basis einer systematischen Literaturrecherche ausgewählt und zur Vorhersage des spezifischen Attributes angewandt. Um die jeweiligen Vorteile bezüglich der Verteilung und Trefferrate des vorhergesagten Attributes ausnutzen zu können, werden Kombinationsvarianten (Ensembling) beider Methoden entwickelt. Es werden Erkenntnisse gewonnen, welche Verfahren die höchste Qualität des fusionierten Datensatzes erreichen.:1. Einleitung 2. Grundlagen der Datenfusion 3. Randbedingungen 4. Vorgehensweise 5.

Den här studien syftar på att undersöka huruvida innehållet i jobbannonser för chefspositioner från offentlig och privat sektor visar tecken på begränsningar samt diskriminering eller mångfald och inkludering. Arbetet är baserat på en kvalitativ analys av innehållet i 55 olika jobbannonser för chefspositioner både i offentlig och privat sektor. Syftet med undersökningen har varit att belysa vilka utmaningar och möjligheter upplevs av utrikesfödda akademiker som ansöker till chefspositioner i Sverige, med hjälp av tidigare forskning inom området och en teoretisk referensram som består av Ackers ojämlikhetssystem (2006), Elias och Scotsons teori om etablerade och outsiders (1999), teorier om diskriminering som lyftes fram av Phelps (1972) och Arrow (1973) samt Becker (1971). Studiens resultat visar att det förekommer både möjligheter och hinder som drabbar utrikesfödda akademiker på den svenska arbetsmarknaden. Möjligheterna återfinns framför allt i jobbannonser som tillhör den offentliga sektorn, medan begränsningarna förekommer i stor utsträckning i båda sektorer, dock oftare i den offentliga. / The present study aims to research whether the content of job ads for leadership positions from the public and the private sector include signs of limitations and discrimination or diversity and inclusion. The research is based on a qualitative analysis of the content in 55 different job ads for leadership positions from both the public and private sectors. The purpose of the study is to showcase the difficulties and the opportunities that foreign born academics are confronted with when applying to leadership roles in Sweden. The theoretical framework consists of Ackers theory of inequality regimes (2006), Elias and Scotsons theory of the established and the outsiders (1999), theories regarding discrimination put forward by Phelps (1972), Arrow (1973) and Becker (1971), as well as previous research in the field of diversity and discrimination. The results show that there are both opportunities and limitations that affect foreign born academics that compete on the Swedish labour market. The opportunities are mostly found in job ads that relate to the public sector, while the limitations are prevalent in both sectors, though they are nevertheless more frequent in the public sector.

Radio frequency (RF) and microwave switches are widely used in several different applications including radar, measurement systems, telecommunications, and other areas. An RF switch can control a radar’s transmit vs. receive mode, select the operating band, or direct an RF signal to different paths. In this study, a single pole eight throw (SP8T) switch using only Surface Mount (SMT) components is designed and simulated in Keysight’s Advanced Design System (ADS). Single pole eight throw is defined as one input and eight possible outputs. A star network configuration with series-shunt PIN diode switches is used to create the 8-way RF switch. There are other commercially available SP8T switches from MACOM, Skyworks, Analog Devices, and other vendors that operate around this bandwidth. However, this design uses SMT components and series-shunt diode configurations to create a device in the GHz range and power handling in the high 20 to 30 dBm range. This study modeled components in ADS, including the PIN diodes and the bias tees. The project also analyzed multiple layouts, finalizing the optimal design to meet specifications. The insertion loss, bandwidth, isolation, return loss, power handling, and switching speed are analyzed in the final design. Key specifications for this design are determined by comparing to other commercially available SP4T and SP8T switches from MACOM, Skyworks, Analog Devices, and other vendors, as well as developing an operational switch over the 2-18 GHz bandwidth. Additional specifications include limiting insertion loss to 2.0 dB maximum and maximizing isolation to 30 dB minimum. Switching speed and power handling specifications are also set to 20 ns and 23 dBm, respectively. Future projects will work on design fabrication and improvements to the manufactured switch.

[pt] Esta dissertação foca no tipo de linguagem usada em anúncios e propagandas de celular e no seu impacto como fonte de informações para o comportamento do consumidor. Esses instrumentos de publicidade podem chegar a não ser compreendidos não só por cerca de 1/3 da população, que é considerada analfabeta funcional geral, mas também por outros que não entendem linguagem técnica e termos estrangeiros. Esse fato pode acarretar grandes perdas financeiras e mau uso da ferramenta de comunicação de marketing. Esta pesquisa foi inspirada no S-TOFHLA, que é um teste internacional de letramento usado na área de saúde. Ela mediu a capacidade dos respondentes de entender aspectos e atributos usados nos anúncios de mídia impressa sobre celulares. Para isso, foi desenvolvido um questionário inspirado na técnica de cloze, que consiste no preenchimento de lacunas com a palavra mais adequada, contendo quatro opções de múltipla escolha para cada questão. Esse teste foi aplicado em 202 respondentes e as respostas contribuíram para avaliar a sua compreensão sobre o tema. Os resultados evidenciam que os respondentes, segundo seus níveis de renda, escolaridade, idade e sexo têm níveis de entendimento diferentes sobre o tema. Quanto maior, por exemplo, o nível de escolaridade do respondente maior a sua pontuação no teste. Isso reforça a idéia de se reavaliar a clareza, a inteligibilidade e a especificidade desses materiais promocionais. Finalmente o estudo salienta a importância de as mensagens e os elementos usados nesses anúncios se tornem instrumentos mais sensíveis ao letramento dos diferentes públicos e consequentemente mais eficazes na comunicação publicitária. O estudo deixa clara a necessidade latente de mudanças para a comunicação de marketing. / [en] This thesis focuses on the type of language used in advertisements and publications for cell phones and its impact as a source of information for the consumer behavior. These publication instruments can actually be not understood by about 1/3 of the population, which is considered functional illiterate, but by others that don’t understand technical languages, jargons, and foreign terms. This fact can result in large financial losses and misapplication of the marketing communication tools. The research at issue was inspired by S-TOHFLA, which is an international test of functional health literacy of patients used in the health care setting. It measured the ability of the respondents to understand aspects and attributes used in press media advertisements about cell phones. Thereto, a test was inspired by the Cloze procedure which consists in fulfilling gaps with the most appropriate word, containing four multiple choice options for each question. That test was administrated to 202 respondents, and the answers contributed to assess their comprehension about the theme. The results point out that the respondents, according to their level of income, literacy, age and gender, have different levels of understanding the subject - for example, the higher the level of literacy of the respondent, the higher his or her score in the test. That reinforces the idea of reassess the clarity, intelligibility and the specificity of these promotional materials. Finally, this study stresses out the importance of messages and elements, used in advertisements, to become more sensitive to the literacy of different audiences and consequently, to be more effective in the advertising community. This study clarifies the latent need of changes for the marketing communication.

<p dir="ltr">Automated Driving Systems (ADS) have evolved significantly over the past decade. With conditionally automated driving systems still requiring constant driver supervision and human intervention upon system request, a driver’s readiness to take over from an ADS has significant safety implications. Research suggests that drivers using ADS are more likely to engage in non-driving-related tasks (NDRTs), and this engagement can deteriorate takeover performance. However, different NDRTs can involve engagement of physical, visual and/or cognitive resources, which all can affect the takeover process in different ways. The potential interaction effects among these factors may be the cause of mixed empirical findings regarding the influence of NDRT engagement on takeover readiness and performance. Additionally, with more advanced ADS, takeover scenarios are likely to be less urgent. Yet, the ways in which drivers behave in response to a takeover request to intervene during such less urgent scenarios while engaged in NDRTs is still not well understood.</p><p dir="ltr">The purpose of this dissertation is to provide a better understanding of drivers’ response behavior during a conditionally automated vehicle takeover process by analyzing drivers’ motor, visual, and cognitive readiness in response to a takeover request (TOR). The work was completed in two phases. The first phase focused on the effects of pre-takeover visual engagement on takeover readiness in urgent situations. Two experiments were conducted as part of this first phase. Particularly, Study 1 investigated drivers’ post-TOR visual attention allocation and cognitive readiness after continuous visual NDRT engagement before a TOR. Study 2 examined drivers’ pre-TOR visual attention allocation and takeover performance both during and after voluntary engagement with visual NDRTs. The second phase used a non-urgent takeover scenario to investigate drivers’ takeover behavior and visual attention allocation when prioritizing the engagement of visual-manual NDRTs that differed in terms of cognitive engagement levels.</p><p dir="ltr">Study 1 required continuous visual attention in NDRTs and manipulated only the location of visual attention before an auditory TOR. Dependent measures included duration, location, and directness eye-tracking measures after the TOR, as well as freeze-probe cognitive readiness scores. Overall, delayed visual attention re-allocation in the driving scene, less dispersed gaze patterns, and worse perception and comprehension of road hazards were associated with off-road visual NDRT engagement. In addition, no significant benefit of enforcing on-road visual attention before the TOR, compared to the baseline condition without NDRT requirements, were found. These findings highlight the need to investigate the effects of more naturalistic NDRT engagement on takeover attention reallocation and takeover performance.</p><p dir="ltr">Study 2 complemented Study 1 by allowing voluntary switching of visual attention between the NDRT and the driving scene prior to the TOR, with the driving task being a priority. In addition, Study 2 investigated drivers’ takeover quality and understanding of the takeover scene using the appropriateness of their takeover decisions. Dependent measures were pre- and post-takeover eye-tracking measures, aligning to those used in Study 1, in addition to motor response measures, longitudinal and lateral vehicle control measures, and decisions made in response to a road obstacle. Overall, the driver’s post-TOR behaviors were not significantly affected by NDRT conditions, but visual NDRT-induced differences in gaze distribution were associated with the appropriateness of takeover decisions.</p><p dir="ltr">Finally, Study 3 used knowledge from prior studies to isolate the effects of different levels of cognitive engagement in real-world visual-manual NDRTs. The purpose was to investigate the effects of cognitive engagement on drivers’ visual attention allocation before and during the takeover, as well as on takeover performance in non-urgent takeover scenarios, where NDRT engagement was a priority. Dependent measures included eye-tracking measures, takeover response time, and vehicle control measures, used in prior studies. In summary, engagement in NDRTs with higher levels of cognitive engagement resulted in significant differences in pre-TOR visual attention allocation and less stable takeover maneuvers.</p><p dir="ltr">The findings from this work contribute to a better understanding of the effects of different components of NDRT engagement on takeover performance in conditionally automated driving systems. Ultimately, this work can contribute to improving the design of next-generation human-machine interfaces in surface transportation, including driver monitoring systems and in-vehicle displays, that promote safer human-automation integration in future ADS.</p>

Advanced Vehicle Systems promise improved safety and comfort for drivers. Steady advancements in technology are resulting in increasing levels of vehicle automation capabilities, furthering safety benefits. In fact, some of these vehicle automation systems are already deployed and available, but with promised benefits, such systems can potentially change driving behaviors. There is evidence that drivers have increased secondary task engagements while driving with automated vehicle systems, but there is a need for a clearer scientific understanding of any potential correlations between the use of automated vehicle systems and potentially negative driver behaviors. Therefore, this thesis aims to understand the state of knowledge on automated vehicle systems and their possible impact on drivers’ distraction behaviors. I have conducted two systematic literature reviews to examine this question. This thesis reports these reviews and examines the effects of secondary task engagement on driving behaviors such as take-over times, visual attention, trust, and workload, and discusses the implications on driver safety.

Air traffic communication is one of the most vital systems for air traffic management controllers. It is used every day to allow millions of people to travel safely and efficiently across the globe. But many of the systems considered industry-standard are used without any sort of encryption and authentication meaning that they are vulnerable to different wireless attacks. In this thesis vulnerabilities within an air traffic management system called ADS-B will be investigated. The structure and theory behind this system will be described as well as the reasons why ADS-B is unencrypted. Two attacks will then be implemented and performed in an open-source air traffic management simulator called openScope. ADS-B data from these attacks will be gathered and combined with actual ADS-B data from genuine aircrafts. The collected data will be cleaned and used for machine learning purposes where three different algorithms will be applied to detect attacks. Based on our findings, where two out of the three machine learning algorithms used were able to detect 99.99% of the attacks, we propose that machine learning algorithms should be used to improve ADS-B security. We also think that educating air traffic controllers on how to detect and handle attacks is an important part of the future of air traffic management.

The paper examines Meta ads in the adult education field. The ads are selected based onfour main criteria, ads with creatives that show people in the profession of the intendededucation, ads that the audience can quickly identify as an educational program, creativeswith a high signal-to-noise ratio and creatives with only one point of focus in the pictures.The ads are analyzed through a semiotic analysis and then the subject of a survey todetermine how they score in regards to informativeness, entertainment, irritation and speedof processing. The paper finds a connection between ads with a high CTR (Clickthroughrate) and high scores in the survey in “informative” and “fast to process” ads. The mainlimitation of the paper is the low amount of partakers in the survey, coupled with the methodof scoring ads based on a survey instead of in their natural habitat, not accounting forbanner blindness and other phenomena related to social media and the web.
