Progressive Web Apps (PWA) is a concept of enhanced web apps which aim to erase the difference between web and native apps. The concept of PWA introduces several benefits, including simpler distribution and development, which makes web apps a viable option for many businesses. The installation process of a PWA is different from native apps and this study aims to understand whether or not it has an impact on the users will to install the PWA. PWA:s are installed directly from the browser, rather than an app marketplace. Said installation process is suspected to be unknown to many which might influence the impact. In this study, several papers on the topic are studied. A PWA is developed from scratch which is used as a platform for a user test, hosting a brief introduction of the topic as well as guiding participants through the installation process. In conjunction with the user test a survey is conducted to collect the impressions from their experience in the user test. The result of the survey shows indications that the suspected lack of knowledge and experience was correct, and that the installation process is not to complicated.Additionally, results show that many probably will not bother to install a PWA, even if it is available. Therefore, I argue that the installation process does have an impact in its current form. Alternatives to the installation process used in this study do exist and are discussed in this paper.

Den snabbt växande teknologiska utvecklingen har gjort att många företag anpassat sina varor,tjänster och företagsstruktur efter det alltmer moderna plattformsmodellen. Denna modell harvisat goda förutsättningar för företag att växa och att skapa ett större interaktionsnätverk mellanandra aktörer och agerar som en bra konkurrenskraft gentemot företag som förhåller sig till entraditionell analog företagsmodell. Denna fallstudie undersöker hur Jägersro Hästcenter kangynnas av en sådan modell och har undersökt vilka olika förslag som hade ökat antalet besökaretill anläggningen. Det har gjorts sju intervjuer samt samlats in 89 svar från en enkätundersökningsom visade hur intresset var starkt bland respondenterna att testa på nya innovativa teknologier. Undersökningen ger även goda stöd för vidare forskning kring hur dessa förslag bästimplementeras för att leda till bäst resultat. / The rapidly growing technological advancements have led many companies to adapt theirproducts, services and corporate structure to the increasingly modern platform model. This modelhas shown great potential for companies to grow and create a larger network of interactions withother stakeholders, serving as a strong competitive advantage compared to companies followinga traditional analog business model. This case study examines how Jägersro hästcenter can benefitfrom such a model and explores various suggestions to increase the number of visitors to thefacility. Seven interviews were conducted, and 89 responses were collected from a survey,revealing strong interest among the respondents in exploring new innovative technologies. Thestudy provides valuable support for further research on how these suggestions can best beimplemented to achieve optimal results.

Enterprise low-code plattformar är något som stora organisationer och företag använder för att möjliggöra organisationsförändringar, orkestrera affärsprocesser och utvinna potential med citizen development. Forskningen runt low-code plattformar ligger dock efter, vilket gör att organisationer blir beroende av marknadsanalytiker och konsulter i den utforskande fasen i deras implementation. För att möta den brist på tidigare forskning inom enterprise low-code plattformar så har vi designat och utfört en fallstudie där vi studerat Arbetsförmedlingens implementation och användning av PegaSystems low-code plattform. Baserat på resultatet från denna studie så har vi tagit fram rekommendationer för framtida implementationer av enterprise low-code plattformar. Vi fann att Pegakompetens, mognad och struktur är viktiga och avgörande faktorer i ett Pegaprojekt. Vi fann också att tidig satsning och prioritering av Pegas Situational Layer Cake är nyckeln för att kunna utnyttja och skapa återanvändning, öka effektivitet, bygga en generisk grund och kunna använda citizen development. Våra rekommendationer till framtida implementationer är därför att (1) prioritera utveckling av Situational Layer Cake (2) Ta fram en projekttidslinje och strategi som är medveten om organisationens egen nivå av Pegakompetens, mognad och struktur.

Purpose: The purpose of this study is to investigate and analyze whether the current platform elements can handle the additional loads from the introduction of platform screen doors at various subway stations. The specific stations involved in the study were Norsborg, Alby, Fridhemsplan, Globen and Alvik. Method: By introducing the platform screen doors, the number of potential accidents is minimized, and the safety of passengers is increased. In order to see if the platforms would be capable of handling the extra load from the platform doors, engineers have measured the thickness of the current platforms to see whether they would be able to withstand the additional pressure that comes with the installation of platform screen doors. Results: Based on the calculations of the different platform types, the results show that platform type 1 can not handle loads from the platform doors and has to be reinforced to minimize the risks of breakage and tilting. Platform types 2 and 3 can manage the weight from the platform doors but should also be reinforced since there is a risk that they will break in the future. In order to achieve safety for people on the platform, the results show that a half-high platform door is the best choice. Conclusions: The available manufacturers on the market offer some different models of platform screen doors, both full and half-height. Since stations and their platform elements vary in design and quality, it is not the optimal choice to have the same type of doors on all stations. The best choice for indoor stations is to install full height screen doors where it is possible. Although, half-height screen doors can be installed on all stations. The half-height screen doors result in the most consistent performance while maintaining the safety of people on the platform.

In today’s platform economy, the postal industry has been disrupted with emerging technologies and changing consumer needs. While the physical letter volumes continue to decrease, postal operators seek new sources of customer value through digital innovations. Digital mailbox is an example of a multisided platform that creates value by connecting two or more customer groups and facilitating interaction or transactions between them. In order to successfully attract both supply and demand to these platforms, the platform provider needs to understand both sides of the market The purpose of this study was to increase the understanding of the needs and expectations of the biggest consumer group of the future, Generation Z, regarding their interaction with different sectors in the Finnish society. Furthermore, the research aim was to shed light on the possible implications that these needs and expectations would have on platform providers. The context for the study was Finland. The study was conducted as a case study for PostNord, a communications and logistics supplier in the Nordics. A qualitative research design included conducting 12 semi-structured interviews with Generation Z representatives, born between 1995 and 2001. Additionally, a mirroring workshop with industry experts was conducted in order to include the perspective of the case company. The results were analysed using a thematic analysis method. The findings of this study show that Generation Z’s choice for device and channels is contextual, depending on the importance and urgency of the matter. Gen Z prefers to receive their communication on one platform instead of many, and often on mobile application. This generational cohort has high expectations regarding the speed of the communication. They expect fast responses that also enable a meaningful dialogue, yet on their own terms. The findings indicate that Gen Z values the human element even in digital communication. They want to receive information that is not only relevant to them, but arrives on the right time and comes from a competent, familiar source. These findings have implications on not only PostNord as a platform provider, but all the potential ecosystem partners. / I dagens plattformsekonomi har postbranschen behövt hantera ny teknik och förändrade konsumentbehov. Medan volymen av fysiska brev fortsätter att minska, söker postoperatörer nya källor till kundvärde genom digitala innovationer. En digital brevlåda är ett exempel på en flersidig plattform som skapar värde genom att ansluta två eller fler kundgrupper, samt underlättar interaktioner eller transaktioner mellan dem. För att framgångsrikt locka både utbud och efterfrågan till dessa plattformar, behöver plattformsleverantörer förstå båda sidor av marknaden. Syftet med denna studie var att öka förståelsen för behov och förväntningar hos framtidens största konsumentgrupp, Generation Z, angående deras interaktion med olika sektorer i det finska samhället. Vidare var målet med forskningen att belysa möjliga konsekvenser som dessa behov och förväntningar skulle ha på plattformsleverantörer. Sammanhanget för studien var Finland. Studien genomfördes som en fallstudie för PostNord, en kommunikationsoch logistikleverantör i Norden. Under en kvalitativ forskningsdesign genomfördes 12 halvstrukturerade intervjuer med Generation Zrepresentanter, födda mellan 1995 och 2001, dessutom genomfördes en workshop med branschexperter för att inkludera fallföretagets perspektiv. Resultaten analyserades med hjälp av en tematisk analysmetod.Resultaten av denna studie visar att Generation Zs val för enhet och kanaler är kontextuell, beroende på hur viktigt och brådskande det är. Generation Z föredrar att ta emot kommunikation på en specifik plattform i stället för många, och ofta på mobilapplikation. Denna kohort har höga förväntningar på kommunikationshastigheten, de förvänta sig snabba svar som också möjliggör en meningsfull dialog, men ändå på deras egna villkor. Resultaten tyder på att Generation Z värderar det mänskliga elementet även i digital kommunikation. De vill ha information som inte bara är relevant för dem, men kommer under rätt tid och från en kompetent, välkänd källa. Dessa resultat har inte bara konsekvenser för PostNord somplattformsleverantör, men alla potentiella partners i ekosystemet.

Space-resolved stimulation of active hydrogel layers can be achieved for example by using a micro-heater array. In the current work, we present the interaction of (i) such a rigid array of heating elements that can be selectively activated and (ii) an active thermo-responsive hydrogel layer that responds to the local stimulus change. Due to the respective local actuation, (iii) the surface form of a passive top-layer can be manipulated. We present continuum-based simulative predictions based on the Temperature Expansion Model and compare them to experimental outcomes for the system.

Many people suffer from diabetes and as a result of the disease, circulatory issues in feet are common. To find such issues at an early stage, Vistafeet were developing a product that measures the temperature in feet. This product needed to be calibrated and for that purpose, this master thesis was evaluating a proposed calibration rig and the possibility of using a digital twin in order to predict the temperature of the rig. The concept of a digital twin includes a physical product, a virtual model of the same product, and information flow between them. By receiving information from the physical product, the digital model should be able to estimate or predict information about the physical product, information that is then used to improve the physical product. In order to be a true digital twin, it should be automatic and in real time. If the data flow is delayed, a better description is digital shadow or digital model, depending on the level of connection. Due to time limitations during this master thesis, the real time connection required for a proper digital twin was not achieved. The scope was then limited from a digital twin to a digital model. The evaluation of the rig was conducted through a case study of the rig including a number of tests, with the purpose of replicating and verifying the result from a previous study by Xiao and Fan [23]. The digital model was made by logging data from the physical product to later use within the simulated environment. First the digital model was compared and adjusted to the information from several thermal points of the physical model. The thermal points were spread out to give as much information as possible the de simulation, but only placed on sides of the rig that would have easy access if the rig were to be used for calibration. Once the digital model was adjusted, the final simulation was made, and temperature data was compared in verification points to see how well the digital model fit the physical model. The verification points were chosen on the calibrating side of the rig and spread out to see if the model managed to predict potentially tricky places. To finalize the investigation of the rig, errors within the model and the rig itself were evaluated. The result showed that it was possible to fulfill the conclusions from a previously made study. The digital model turned out to be accurate and managed to predict the temperature down to ± 0,1 degrees for most verification points. However, one verification point close to a heater element had much less accuracy than the rest. The result was still acceptable, but this indicates that it is not possible to assume that the model can predict entirely correct temperature within the whole rig only because some points are correct. Especially if trying to predict temperature in more difficult places such as close to a heater. The investigation of errors within the digital model showed that the digital model simulated well within the limits as the temperature range and the controller changed. The sensor close to the heater remained in the same error range as in the first simulation. The errors in hardware were evaluated and the variation between sensors was measured to about 0,1 degrees. However, there might also be a slight offset from the true temperature due to errors affecting all thermistors equally. Even though a 0,1 resolution between sensors is quite good, it is insufficient resolution for this test since the errors in the tests were about ± 0,1 degrees. Despite that, the error of the simulation was still in an acceptable range for a digital model setup. For further improvement, a proper real time digital twin could be implemented, but also higher resolution sensors are required. / Många människor lider av diabetes och som ett resultat av denna sjukdom är cirkulations problem i fötter vanligt. För att på ett tidigt stadie upptäcka sådan problem utvecklade Vista feet en produkt som mäter temperaturen i fötterna för att upptäcka cirkulationsproblem. För att produkten ska fungera måste sensorerna i den kalibreras. I detta examensarbete görs en utvärdering av ett förslag på en kalibreringsrigg. Även möjligheten att använda en digital tvilling för att förutspå temperaturen kommer utvärderas. En digital tvilling inkluderar en fysisk produkt, and virtuell modell av samma produkt samt informationsflöde mellen dem. Genom att få information från den fysiska produkten ska den digitala modellen kunna uppskatta eller förutse information om den fysiska produkten, information som används för att förbättra den fysiska produkten. För att vara en äkta digital tvilling ska informationsflödet ske automatiskt och i realtid. Om informationsflödet sker i efterhand, är en bättre beskrivning en digital skugga eller en digital modell, beroende på nivån av automation och fördröjning. På grund av tidsbegränsning i examensarbetet var det inte möjligt att göra en realtidsuppkopplad digital tvilling, och omfattningen av arbetet begränsades till en digital modell. Utvärderingen av riggen gjordes i form av en fallstudie innehållande ett antal test och genom en replikering av en tidigare gjord studie av Xiao och Fan [23]. Den digital modellen gjordes genom att data från den fysiska produkten sparades och sedan användes för att genomföra den digitala simuleringen. Den digital modellen and passades sedan efter informationen i ett antal ”termiska” punkter (thermal points). Dessa punkter var utspridda för att ge så mycket information som möjligt, men enbart placerade på sidor som lätt kan nås om riggen skulle användas för kalibrering. När modellen var anpassad gjordes en sista simulering. Då jämfördes temperaturen i ett antal verifieringspunkter (verification points) för att se om modellen lyckades förutspå temperaturen i dess punkter. Verifieringspunkterna var på kalibreringssidan av riggen, utspridda för att se om modellen klarade att förutspå även potentiellt svåra platser. Slutligen undersöktes även felkällor i modellen och i riggen. Resultatet av studien visade att det var möjligt att uppfylla slutsatserna från den replikerade rapporten. Den digitala modellen blev mycket noggrann och lyckades förutse temperaturen med en noggrannhet på ± 0,1 grad för de flesta punkterna. Det var dock tydligt att det simulerade värdet i en punkt nära ett element hade betydligt sämre noggrannhet än resten av punkterna. Det var fortfarande en godkänd noggrannhet, men den stora variationen från övriga punkter tyder på att bara för att resultatet stämmer bra i vissa punkter så stämmer det nödvändigtvis inte lika bra i alla punkter. Speciellt om det är en punkt som avviker från övriga och därmed är svårare att uppskatta, som i detta fall, nära ett element. Undersökningen av fel i den digitala modellen visade att den stämde fortsatt bra även när temperaturen och kontrollsystemet ändrades, även om noggrannheten på sensorn nära värmaren var fortsatt låg, var det på ungefär samma nivå. I hårdvaran uppmättes skillnaden i temperatur som termistorerna mätte till 0,1 grad. Dock är det sannolikt ett lite större konstant fel då hårdvaru felen ofta påverkar alla termistorer lika. En noggrannhet mellan sensorerna på 0,1 grad är bra, men inte tillräckligt när felet mellan den simulerade modellen och mätta temperaturen är ± 0,1. Trots det är felet inom gränsen för vad som är acceptabelt för en digital modell. För att förbättra arbetet skulle in riktig realtidsuppkopplad tvilling kunna implementeras, men det krävs också att sensorerna har högre upplösning.

Background – Digitalization and the utilization of ICTs in healthcare have revolutionized the healthcare industry through digital healthcare platforms (DHP). ICTs and DHP’s are highly beneficial for those who have the ability to use them, meanwhile increasing the digital segregation for those who cannot, e.g., elderly generations. Although, elderly generations can particularly benefit from utilizing DHP’s, e.g., enabling independent living. Furthermore, the elderly population is expected to grow globally in the upcoming years, which affects governmental expenditures on healthcare. Purpose – The aim of this study is to investigate what causes elderly not to adopt and use DHP’s, i.e., investigate and develop a deeper understanding of the central barriers for elderly. Furthermore, the second aim is to investigate how DHP providers better can facilitate increased adoption and usage among the elderly generations. Method – This study followed an abductive research approach of a single case company that offers healthcare services through a digital platform. To answer research questions, we primarily used a qualitative research method as well as quantitative data to strengthen our findings. In total, 22 qualitative interviews were conducted with respondents over 65. The interviews were divided between previous users of digital health platforms and non-users. The quantitative data were analyzed through SPSS where uni- and bivariate analysis was performed. Findings – Our finding disclosed that elderly experience mainly two barriers for adoption of DHP’s among elderly: negative attitudes and technology anxiety and one barrier for both adoption and usage: trust. This adds to the previous literature which has not made any distinction between adoption and usage of DHP’s among elderly. Furthermore, this study provides direct development suggestions that can enable increased adoption and usage. Theoretical implications – This study contributes to previous digital health literature by considering digital platforms a part of healthcare. We contribute with deepened knowledge regarding barriers that hinders adoption for elderly and by suggesting development suggestions that are able to bridge each barrier. Managerial implications – The managerial implications of this research are directed towards DHP providers on how they can facilitate increased adoption and usage respectively. The implications include design and marketing options that are able to enable the objective.

[pt] Nesta tese, examinamos como as Tecnologias da Informação e da Comunicação (TICs) se desenvolveram na China a partir de especificidades históricas, do papel do Estado e das empresas privadas de tecnologia, organizadas dentro de uma economia de plataformas, considerada setor estratégico para a política de modernização empreendida pelo Estado chinês. Esta pesquisa está situada no subcampo da Economia Política da Comunicação (EPC), derivada da Crítica da Economia Política que, por seu caráter transversal a diferentes campos das Ciências Sociais, pode fornecer ferramentas importantes para compreender fenômenos comunicacionais e culturais nas novas configurações das sociedades informacionais. Definimos como objetivos deste trabalho reconstruir o caminho do desenvolvimento das Tecnologias de Informação e Comunicação (TICs) na China nos séculos XX e XXI e seus impactos econômicos e políticos, além de examinar como se estruturam as big techs chinesas e suas versões globais, suas características e como tais empresas privadas se relacionam com o Estado. Utilizamos como procedimentos metodológicos a pesquisa bibliográfica e a análise documental, contemplando uma literatura que permite olhar a China a partir de sua experiência imperial e revolucionária, além de discussões conceituais sobre plataformas e o processo de enraizamento de estruturas digitais na vida cotidiana, chamado de plataformização. A análise de documentos permitiu mapear o estado da plataformização na China, os desafios, os tensionamentos e como isso se articula dentro da nova onda de progresso técnico com consequências diretas sobre dinâmicas de produção e de acumulação de capital. Concluímos que, embora o desenvolvimento das TICs tenha conduzido a China a desafios semelhantes aos enfrentados por países ocidentais como a formação de monopólios de empresas de plataformas, cujos modelos de negócios estão amparados na coleta e análise massiva de dados, há especificidades importantes que não permitem o mero espelhamento das estruturas das plataformas chinesas com as ocidentais, notadamente as estadunidenses. Tendo tomado, inicialmente, as plataformas dos EUA como inspiração, as chinesas aproveitaram brechas dentro da organização chinesa para desenvolver arranjos absolutamente particulares nos níveis social e econômico e também político. / [en] In this thesis, we examine how Information and Communication Technologies (ICTs) have developed in China based on historical specificities, the role of the State and private technology companies structured within a platform economy model, considered a strategic sector for the modernization policy deployed by the Chinese State. This research is situated in the subfield of the Political Economy of Communication (PEC) context, which derives from the Critique of Political Economy, which in turn, due to its transversal nature across different fields of Social Sciences, it can provide important tools to understand communication and cultural phenomena in the new configurations of information societies. The objectives of this work are to reconstruct the path of development of Information and Communication Technologies (ICTs) in China in the 20th and 21st centuries, and to examine their economic and politic impacts. Additionally, the study will analyze how Chinese big techs and their global versions are structured, their characteristics, and how such private companies relate to the State. In this research, we use bibliographic research and documentary analysis as methodological procedures, contemplating literature that allows us to look at China from its imperial and revolutionary experience, as well as conceptual discussions on platforms and the process of embedding digital structures in everyday life, called platformization. Document analysis allowed us to map the state of platformization in China, the challenges, the tensions, and how this articulates within the new wave of technical progress with direct consequences on production dynamics and capital accumulation. We conclude that although the development of ICTs has led China to challenges similar to those faced by Western countries, such as the formation of platform company monopolies, whose business models are supported by massive data collection and analysis, there are important specificities that do not allow a mere reflection of Chinese platform structures with Western ones, notably American ones. Having initially taken inspiration from North American platforms, the Chinese have taken advantage of gaps within the Chinese organization to develop arrangements that are absolutely particular at the social, economic and political levels.
