Standardized, collaborative decision-making processes have already been implemented at some network-relevant airports, and these can be further enhanced through data-driven approaches (e.g., data analytics, predictions). New cost-effective implementations will also enable the appropriate integration of small and medium-sized airports into the aviation network. The required data can increasingly be gathered and processed by the airports themselves. For example, Automatic Dependent Surveillance-Broadcast (ADS-B) messages are sent by arriving and departing aircraft and enable a data-driven analysis of aircraft movements, taking into account local constraints (e.g., weather or capacity). Analytical and model-based approaches that leverage these data also offer deeper insights into the complex and interdependent airport operations. This includes systematic monitoring of relevant operational milestones as well as a corresponding predictive analysis to estimate future system states. In fact, local ADS-B receivers can be purchased, installed, and maintained at low cost, providing both very good coverage of the airport apron operations (runway, taxi system, parking positions) and communication of current airport performance to the network management. To prevent every small and medium-sized airport from having to develop its own monitoring system, we present a basic concept with our approach. We demonstrate that appropriate processing of ADS-B messages leads to improved situational awareness. Our concept is aligned with the operational milestones of Eurocontrol’s Airport Collaborative Decision Making (A-CDM) framework. Therefore, we analyze the A-CDM airport London–Gatwick Airport as it allows us to validate our concept against the data from the A-CDM implementation at a later stage. Finally, with our research, we also make a decisive contribution to the open-data and scientific community.

Passive Coherent Location (PCL), eller Passiv Radar som det populärt kallas, är enteknologi inom radarlära som innefattar radartyper som inte själva skickar ut elektromagnetiska vågor för att finna och undersöka ett mål. Istället använder sig dessa radartyper av befintliga signaler, såsom radio- och TV-sändningar för att detektera mål. På så vis är det betydligt svårare att upptäcka en passiv radar jämfört med en traditionell aktiv radar. SAAB utvecklar teknologi och metoder för passiva radarsystem. För att få en förståelse för ett av deras PCL-systems prestanda behöver SAAB utveckla en enkel metod för att fastställa radartäckningen. Som ett steg till detta har SAAB därför givit författaren till denna rapport i uppgift att skapa ett gränssnitt som kombinerar och jämför PCL-systemet med detektioner från en automatic dependent surveillance broadcast (ADS-B). Detektionerna från ADS-B kan då fungera som ett facit för hur väl PCLsystemet tar upp detektioner. Vilket ger gränssnittets användare en god indikationför PCL-systemets utsträckning och reliabilitet. Intervjuer hölls med anställda på SAAB som har erfarenhet av att arbeta med likvärdiga system och dess gränssnitt. Intervjuerna var semistrukturerade med frågor som syftade att utforska vilka funktioner som uppskattas och vilka svårigheter deltagarna ser i nuvarande gränssnitt. Utefter deltagarnas svar på intervjuerna byggdes en behovsanalys som tillsammans med teorier inom området låg till grund för utformningen av gränssnittsprototypen. Lösningsförslaget är en gränssnittsprotyp som visar datapunkter där detektion av mål visas från PCL-systemet och ADS-B. / Passive Coherent Location (PCL), or more popularly known as Passive Radar, is a subgenre within the field of radartechnology which includes radar types that does not transmit electromagnetic signals by themselves to find and investigate targets. Instead, they use already existing transmission, such as radio and TV broadcasts, to detect a target. Thus, it is much harder to discover a passive radar compared to a traditional active radar. SAAB is developing technologies and methods for passive radar systems. To get an understanding of the performance of one of their PCL systems, SAAB is looking for a simple method to determine the coverage of the radar. As part of this SAAB has given the author of this report the task of developing an interface which combines and compares the PCL-system with the detections of an automatic dependent surveillance broadcast (ADS-B). The detections from the ADS-B can then act as an answer key for how well the PCL-system detects targets. Thus, giving the interfaces user a good indication for the PCL-systems coverage and reliability. Interviews were conducted with SAAB employees experienced in working with similar systems and their interfaces. These interviews were semi-structured, with questions aiming to explore appreciated features and identified challenges in the current interfaces. A needs analysis was constructed based on the participants answers in the interviews, which, combined with theories within the field served as the foundation for designing the interface prototype. The proposed solution is an interface prototype, displaying data points from the PCL system and ADS-B.

We study a free quantum scalar field in the BTZ spacetime as a model of the AdS/CFT correspondence for black holes, and show the essential steps in computing Bogolyubov coefficients between modes on either side of the wormhole. As background, we review the BTZ geometry in standard, Kruskal and Poincaré coordinates, holographic renormalisation of the dual field theory and canonical quantisation in curved spacetime. / Vi studerar ett fritt skalärt kvantfält i BTZ-rumtiden som en modell av AdS/CFT-dualiteten för svarta hål och visar huvudstegen i beräkningen av Bogolyubov-koefficienter mellan moder på olika sidor av maskhålet. Som bakgrund redogör vi för BTZ-geometrin i standard-, Kruskal- och Poincarékoordinater, holografisk renormering av den duala fältteorin och kanonisk kvantisering i krökt rumtid.

We study constraints imposed on a general unitary two-dimensional conformal field theory by modular invariance. We begin with a review of previous bounds on the conformal dimension Delta1 of the lowest primary operator assuming unitarity, a discrete spectrum, modular invariance, cL, cR > 1, and no extended chiral algebra. We then obtain bounds on the conformal dimensions Delta2, Delta3 using no additional assumptions. We also show that in order to find a bound for Delta4 or higher Deltan, we need to assume a larger minimum value for ctot that grows logarithmically with n. We next extend the previous results to remove the requirement that our two-dimensional conformal field theories have no extended chiral algebra. We then show that modular invariance also implies an upper bound on the total number of states of positive energy less than ctot=24 (or equivalently, states of conformal dimension between ctot=24 and ctot=12), in terms of the number of negative energy states. Finally, we consider the case where the CFT has a gravitational dual and investigate the gravitational interpretation of our results. Using the AdS3/CFT2 correspondence, we obtain an upper bound on the lightest few massive excitations (both with and without the constraint of no chiral primary operators) in a theory of 3D matter and gravity with Lambda < 0. We show our results are consistent with facts and expectations about the spectrum of BTZ black holes in 2+1 gravity. We then discuss the upper and lower bounds on number of states and primary operators in the dual gravitational theory, focusing on the case of AdS3 pure gravity.

Hydrodynamics is an effective theory that is extremely successful in describing a wide range of physical phenomena in liquids, gases and plasmas. However, our understanding of the structure of the theory, its microscopic origins and its behaviour at strong coupling is far from complete. To understand how an effective theory of dissipative hydrodynamics could emerge from a closed microscopic system, we analyse the structure of effective Schwinger-Keldysh Closed-Time-Path theories. We use this structure and the action principle for open systems to derive the energy-momentum balance equation for a dissipative fluid from an effective CTP Goldstone action. Near hydrodynamical equilibrium, we construct the first-order dissipative stress-energy tensor and derive the Navier-Stokes equations. Shear viscosity is shown to vanish, while bulk viscosity and thermodynamical quantities are determined by the form of the effective action. The exploration of strongly interacting states of matter, particularly in the hydrodynamic regime, has been a major recent application of gauge/string duality. The strongly coupled theories involved are typically deformations of large-$N$ SUSY gauge theories with exotic matter that are unusual from a low-energy point of view. In order to better interpret holographic results, an understanding of the weak-coupling behaviour of such gauge theories is essential. We study the exact and SUSY-broken N=1 and N=2 super-QED with finite densities of electron number and R-charge, respectively. Despite the fact that fermionic fields couple to the chemical potentials, the strength of scalar-fermion interactions, fixed by SUSY, prevents a Fermi surface from forming. This is important for hydrodynamical excitations such as zero sound. Intriguingly, in the absence of a Fermi surface, the total charge need not be stored in the scalar condensates alone and fermions may contribute. Gauss-Bonnet gravity is a useful laboratory for non-perturbative studies of the higher derivative curvature effects on transport coefficients of conformal fluids with holographic duals. It was previously known that shear viscosity can be tuned to zero by adjusting the Gauss-Bonnet coupling, &lambda;_GB, to its maximal critical value. To understand the behaviour of the fluid in this limit, we compute the second-order transport coefficients non-perturbatively in &lambda;_GB and show that the fluid still produces entropy, while diffusion and sound attenuation are suppressed at all order in the hydrodynamic expansion. We also show that the theory violates a previously proposed universal relation between three of the second order transport coefficients. We further compute the only second-order coefficient thus far unknown, &lambda;₂, in the N=4 super Yang-Mills theory with the leading-order 't Hooft coupling correction. Intriguingly, the universal relation is not violated by these leading-order perturbative corrections. Finally, by adding higher-derivative photon field terms to the action, we study charge diffusion and non-perturbative parameter regimes in which the charge diffusion constant vanishes.

"It is the purpose of this study to determine the type of appeal, the size and cost, the plan of insertions, and the extent superlatives are used in The Dallas Morning News used car advertisements of twenty automobile dealers during the month of April. Fourteen advertising appeals were used by the twenty automobile dealers advertising in The Dallas Morning News in the month of April. The fourteen appeals used were: efficiency, friendliness, style, curiosity, safety, convenience-comfort, economy reliability-reputation, durability-dependability, social distinction, fear-caution, ambition, pleasure, and family affection. The economy was the one most used appeal by the dealer. As shown in Table 12, the number of advertising appeals used corresponds or exceeds very little the total number of advertising insertions. Excepting one case, the dealers place the largest advertisements in the Sunday paper. The general procedure was that of placing large advertisements in the Sunday paper and smaller ones throughout the week. The total cost for the twenty automobile dealers was $6,452.08. The total advertising cost per dealer ranged from $38.20 to $1613.81. Only nine of the twenty dealers used superlatives in advertising during the month of April. The nine dealers used nine different superlatives for a total of 281 times."--leaves 1 and 35.

As such, this world features countless characteristics that can be noticed in the various aspects of the contemporary society. One of them is advertising. Therefore, this work will focus on some of the characteristics of the postmodernity applied to the context of advertising. Objectively, this application is named here as the use of specific characteristics of printed media. This dissertation discusses, thus, the creative strategy that uses the specific characteristics of printed media (newspapers and magazines) in the language of advertising. Specific characteristics are understood as the physical elements of newspaper and magazine support, such as paper grammage, book spine, the staples of a magazine, etc. used in ads. Therefore, this work highlights ads in newspapers and magazines with an unusual format, that is, which go beyond the mainstream format of ads. This creative strategy makes use of several characteristics of post-modernity that are analyzed in the selected corpus, composed by more than a hundred ads. In a certain historical moment, the use of this creative strategy becomes frequent, influenced by several factors that are studied considering the evolution of printed ads in Brazil. Finally, with a methodology that systematizes common aspects in a group of possibilities, a taxonomy that considers the different specifications for the use of newspapers and magazines; the production factors; the creative resources and the exploration of the senses. / Vivemos num mundo pós-moderno. Como tal, este mundo apresenta inúmeras características que podem ser verificadas nos muitos aspectos da sociedade contemporânea, um deles é a publicidade. Assim, este trabalho vai focalizar algumas das características da pós-modernidade aplicadas ao contexto da publicidade. Objetivamente, essa aplicação foi aqui denominada de uso das características específicas do meio impresso. Esta dissertação discute, portanto, a estratégia criativa que usa as características específicas dos meios impressos jornal e revista no discurso publicitário. Como características específicas vamos entender os elementos físicos do suporte jornal e revista, como a gramatura do papel, a lombada, os grampos de uma revista etc. usados no anúncio publicitário. O trabalho destaca, portanto, a publicidade veiculada em jornais e revistas com formato diferenciado, ou seja, que extrapola o formato padrão de anúncio. A estratégia criativa em questão utiliza várias características da pós-modernidade que são analisadas no corpus selecionado, composto por mais de cem anúncios publicitários. Em determinado momento histórico, o uso desta estratégica criativa torna-se freqüente, por influência de vários fatores, que são estudados considerando a evolução do anúncio publicitário impresso no Brasil. Por fim, através de uma metodologia que sistematiza aspectos comuns em um conjunto de possibilidades é apresentada uma taxionomia que considera as diferentes especificidades de aproveitamento do meio jornal e revista; os fatores de produção; os recursos criativos e a exploração dos sentidos.

Facebook is today the biggest ads platform in the world. This makes it strategi- cally smart for companies to run their ads on the platform. To follow up the result from these ads is an important part for the companies to know if the target audience is the right one. The purpose with this thesis was to investigate if it’s possible for the company Leeroy to develope their own system that follow up ad conversion for Facebook ads. But also investigate how to implement Facebook’s own system and if other systems could be used. From this two purposes a number of goals have been set, which all could be answered. A pilot study resulted in the gathering of information if an own solution could be implemented. The result of this pilot study results in the answer no, an own solution could not be implemented at this state. Through the pilot study a recommended solution could be presented where Facebook’s system is the recommended way to go. This result is based on a system comparison between Facebook and Google Firebase. This recommended solution has resulted in a implementation guide that Leeroy can use to implement Facebook SDK in their application portfolio based on React Native. / Facebook är idag världens största annonsplattform vilket gör det strategiskt smart för företag att annonsera sin produkt eller sina tjänster på plattformen. Att följa upp resultatet av dessa annonser är för företagen en viktig parameter för att veta om den annonserade målgruppen är rätt. Syftet med detta arbete var att undersöka om ett eget system för mobilapplikationer hos företaget Leeroy kan utvecklas för uppföljning av annonskonverteringar hos Facebook-annonser och hur Facebooks egna system implementeras och om andra system går att använda. Utifrån detta syfte kunde ett antal mål fastställas som alla kunde besvaras. Utifrån en förstudie kunde information insamlas om hurvida en egen lösning går att tillämpa. Vilket resulterat i svaret nej, det är idag inte möjligt att utveckla en egen lösning. Genom förstudiens resultat kan en rekommenderad lösning presenteras där Facebooks system rekommenderas utifrån en jämförelse mellan Facebook och Google Firebase. Denna rekommenderade lösning har resulterat i en implementationsguide som Leeroy kan använda för att implementera Facebook SDK i sin applikationsportfölj baserat på React Native.
