This research paper delves into the integration of artificial intelligence (AI) in the process of user experience (UX) design resulting in more-than-human-made designs. Specifically, the study focuses on the utilization of the text-to-image AI tool, Midjourney. The primary research questions addressed in this paper are twofold: 1) How do AI tools influence the current UX design process of a high-fidelity prototype? and 2) How do more-than-human-made high-fidelity prototypes compare with human-made high-fidelity prototypes in terms of UX? To answer these research questions, a two-method study design was employed. Firstly, two focus groups with in total of 8 designers as participants were formed, with one group utilizing Midjourney to investigate its influence on the design process and to compare the two groups regarding their workwise. The aim was to create two comparable prototypes within a specific e-commerce setting. Secondly, a between-subjects design user study with 32 participants was conducted to test the high-fidelity prototypes and to assess any potential disparities in UX quality between them. The findings regarding the first research question indicate that Midjourney primarily serves as an inspirational tool. Designers were able to harness the AI tool to generate dark mode images, with the final chosen dark mode exemplifying the impact of Midjourney. Additionally, designers attempted to utilize the tool for creating icons. Regarding the second research question, the user study revealed that, despite similar and comparable use cases, there were only minor significant differences in terms of UX quality. The overall scores in System Usability Scale (SUS) and User Experience Questionnaire Plus (UEQ+) did not exhibit any significant disparity. This study suggests that while Midjourney proves to be a useful tool within the design process, its current influence on designers' UX design process and the ultimate performance of the final prototype remains relatively modest. Further research and development may be required to enhance its impact in the field of UX design and the study design should be used to test other AI tools in comparable settings.

We have come a long way in the pursuit of reducing our carbon footprint from our way of living, bycontinuously development of batteries and charging infrastructure for electric vehicles to decrease thedemand for fossil fuels, improving the overall energy efficiency and to increase awareness of the problemto the population. One of the industries, that during the last decades has undergone vast improvements,is the development of the airplane engines due to increased emission regulations, for the aviationindustry, and to reduce the costs of air travel. Despite tighter regulations, global impact from travellingby air is increasing due to the explosive increase in number of travels and travellers. In order to copewith the situation, it is of course necessary to further develop fuel and emission effective airplanes, butalso to study the whole chain of emission sources correlated to the air transport industry. So, whilewaiting for improved airplanes there are well known emission effective technologies that can beimplemented already today – implement electric vehicles as support vehicles at airports.Today, and throughout history, most of the focus of air travel has been on the airplane itself. This thesis,that was carried out at KTH Royal Institute of Technology during late spring and autumn 2018, didinstead study the support vehicles used in airports. In this thesis, a generic economic model wasdeveloped in order to estimate the costs involved when replacing traditionally vehicles to suggestedelectrically propelled alternatives. To test and support the development of an economic model, a casestudy has been carried out at Stockholm Arlanda Airport. This case study included a field study to thementioned airport, and in combination with interviews with former employees from one of the groundhandling companies that are currently active in the airport. Raw data was collected over the equipmentand vehicles currently in use. This data was used to describe the vehicles purpose, requirements and toensure that the alternative electric vehicles proposed would offer at least the same performance as thetraditional vehicles. The developed generic economic model was modulated with five stages thatrepresented a selection of input parameters. The collected data became a result in itself and was used asinput to three concurrent theses.The results from the five stages presents the costs during an investment period of between of one tofifteen years. One of the most significant result could be seen from Stage V. This stage showed that thecombined cost to replace all vehicles currently used, with either all new diesel vehicles or electricalternative vehicles, are lower for electric vehicles than for diesel vehicles. Another significant resultcould be seen from the investigation of Stage IV, Stage IV-B, were the model was modulated to representthe case of replacing a vehicle. The results showed that the Letter and Cargo procedures, that travel thefarthest and has the highest fuel consumption of the investigated vehicles, had negative costs throughthe whole investment period. This means that the expenses will always be lower when these vehicles arereplaced. The model was validated through a sensitivity analysis, performed on the discount rates,depreciation rates and as well as costs for battery replacement during the depreciation period. / Vi har kommit långt i vår strävan att minska vårt koldioxidavtryck genom vårat sätt att leva, genom attkontinuerligt utveckla batterier och laddningsinfrastruktur för elfordon med syftet att minskaefterfrågan på fossila bränslen, förbättra den totala energieffektiviteten och öka befolkningensmedvetenhet om problemet. En av de branscher, som under de senaste decennierna har genomgått storaförbättringar, är utvecklingen av flygplansmotorer och regler för flygplan. Men eftersom antaletflygresenärer fortsätter att öka årligen krävs ytterligare arbete för att förbättra den totala effektivitetenoch minska det negativa globala avtrycket från flygresor. Medan väntan på att morgondagens flygplanska utvecklas så finns det teknik som redan kan appliceras idag – elfordon.I dag, och genom historien, har det mesta av all fokus för flygresor varit på flygplanen själva. Dettaexamensarbete, som genomfördes på KTH, Kungliga Tekniska Högskolan, under den senare delen avvåren och hösten 2018, utredde istället de fordon som omger ett flygplan, under den tid flygplanet stårstilla på en flygplats. Under denna uppsats utvecklades en generisk ekonomiskmodell, med syftet attestimera kostnaderna att ersätta och använda elfordon istället för de nuvarande fordonen. För attutveckla den ekonomiska modellen genomfördes en fallstudie på Stockholm Arlanda Airport.Fallstudien innehöll en fältundersökning till den nämnda flygplatsen, och i kombination med intervjuermed tidigare anställda från ett av de marktjänstföretag som är verksamma på flygplatsen, insamladesrådata om vilken utrustning och fordon som vid tillfället användes. Denna data användes för att beskrivafordonens syfte, vilka krav som ställs på fordonen. Detta var för att säkerställa att det valda elfordonetkunde utföra uppgiften. Den utvecklade generiska ekonomiska modellen modulerades med fem steg,som representerade vilka indataparametrar som bör väljas. De insamlade uppgifterna blev ett resultat isig och användes som indata till tre samtidiga avhandlingar.Den generiska modellen resultat presenterade kostnaderna från de fem stegen under en varierandeinvesteringsperiod på ett till femton år. Ett av de viktigaste resultaten var från Steg V, som visade attden sammanlagda kostnaden för att ersätta alla de fordon som för närvarande används, med antingenalla nya dieselfordon eller elektriska alternativa fordon, är lägre för elfordon än för dieselfordon. Detandra betydande resultatet kommer från undersökningen av Steg IV, Steg IV-B. I Steg IV-B moduleradesmodellen i syfte att representera scenariot då ett fordon ska ersättas, där Letter och Cargo procedurernavar de som färdades längst och även har den högsta bränsleförbrukningen utav de undersökta fordonen,hade en negativ kostnad under hela investeringslängden. Detta betyder att kostnaderna alltid är lägre,om fordonet ersätts. Modellen har validerats med hjälp utav en känslighetsanalys som utfördes pådiskonteringsräntan, avskrivningssatsen och kostnader för ersättningsbatterier.

The research reported in this dissertation focuses on the development of optimization tools for the design of subsystems in a modern aircraft power distribution system. The baseline power distribution system is built around a 270V DC bus. One of the distinguishing features of this power distribution system is the presence of regenerative power from the electrically driven flight control actuators and structurally integrated smart actuators back to the DC bus. The key electrical components of the power distribution system are bidirectional switching power converters, which convert, control and condition electrical power between the sources and the loads. The dissertation is divided into three parts. Part I deals with the formulation of an optimization problem for a sample system consisting of a regulated DC-DC buck converter preceded by an input filter. The individual subsystems are optimized first followed by the integrated optimization of the sample system. It is shown that the integrated optimization provides better results than that obtained by integrating the individually optimized systems. Part II presents a detailed study of piezoelectric actuators. This study includes modeling, optimization of the drive amplifier and the development of a current control law for piezoelectric actuators coupled to a simple mechanical structure. Linear and nonlinear methods to study subsystem interaction and stability are studied in Part III. A multivariable impedance ratio criterion applicable to three phase systems is proposed. Bifurcation methods are used to obtain global stability characteristics of interconnected systems. The application of a nonlinear design methodology, widely used in power systems, to incrementally improve the robustness of a system to Hopf bifurcation instability is discussed. / Ph. D.

More-than-human design represents a paradigm shift that decentralises the human in relation to the rest of the living world. As part of this movement, scholars call for a new worldview that recognizes the interconnectedness between human and non-human beings. Prior studies have focused on the experience of human-human connections, leaving the more- than-human largely unexplored. Addressing this gap, this study explores design strategies for fostering feelings and reflections of interconnectedness towards the more-than-human world and associated emotions. With a research-through-design methodology, two workshops were conducted, resulting in six key design strategies and an "interconnectedness experience framework". The strategies were evaluated through a prototype in partnership with AquaPrint, a Swedish company that up-cycles fishing nets into designer furniture. Future research should evaluate the strategies individually and in combinations as well as in a field setting. The presented framework and strategies are intended for practitioners as inspiration in design projects to promote noticing the more-than-human world, and encouraging a posthuman perspective.

The promise of smart cities to deliver new urban efficiencies and optimizations for sustainability is increasingly being questioned for its anthropocentric, universal, and top-down perspectives. Framingcities as computers has been critiqued for its limiting understanding of cities, as well as its lack of dealing with the complexities of real messy cities, with diverse knowledge and lived experiences. However, smart technologies have also been highlighted as having the potential to help us better understand more-than-human perspectives and to reconnect us to the world around us. Situated in thefield of design for social innovation, this thesis contributes to the emerging body of work that is exploring how digital urban environments can include local knowledge and more-than-human perspectives. In a co-design process with the urban agriculture community of Sjöbergen in the city of Gothenburg in Sweden, this thesis explores how local knowledge and values about- and in urban nature can help us think differently about the future of sustainable smart city concepts. With a design process guided by research through design and co-design, this thesis is imagining other smart city narratives that go away from the current top-down and universal perspectives and instead are inspired by values of Sjöbergen of reuse, maintenance, collectivity, and knowledge sharing. The design contribution of this work is a design proposal of a smart city service that reuses old smartphones of citizens into smart city technologies for individual and situated purposes. The design proposal aims to show an alternative view of smart cities grounded in local values and more-than-human perspectives.
