A COMPARISON OF TERRAFORM AND ANSIBLE ON PROXMOX VE
No full textAtt administrera enheter manuellt är tidskrävande och ineffektivt. För att möta dessa utmaningar används automatiseringsverktyg såsom Ansible och Terraform för att effektivisera hanteringen av virtualiserade miljöer. Detta examensarbete undersöker hur dessa verktyg kan implementeras i Netcenter för att automatisera Proxmox-miljöer. Syftet med detta arbete är att jämföra vilket av verktygen mellan Terraform och Ansible som är mest lämpligt för att automatisera Netcenters Proxmoxservrar. Netcenter är den av Mälardalens universitet och tillhandahåller fysiska servrar för nätverksstudenter. Jämförelsen baseras på tre aspekter, prestanda, begränsningar och användarvänlighet. Utifrån syftet formulerades tre frågeställningar. Den första undersöker vad det ena verktyget kan göra som inte det andra kan. Den andra fokuserar på prestanda genom att analysera körtid, CPU- och RAM-användning. Den tredje frågeställningen tittar på användarvänligheten hos respektive verktyg. Genomförandet bestod av tre tester för respektive verktyg som skulle representera olika automatiseringsscenarier. Resultatet visade att Terraform hade snabbast körtid och hade fler funktioner, medan Ansible uppvisade lägre CPU- och RAM-användning. Jämförelserna gjorde det möjligt att dra slutsatsen att Terraform är det automatiseringsverktyg som är bättre när det kommer till att skapa och hantera virtuella maskiner för Netcenters Proxmox servrar.Manually administering devices is time-consuming and inefficient. To overcome these challenges, automation tools such as Ansible and Terraform are used to manage virtualized environments. This thesis investigates how these tools can be implemented at Netcenter to automate Proxmox Environments. The aim of this thesis is to compare which of the tools, Terraform or Ansible, is most suitable for automating Netcenter’s Proxmox servers. Netcenter is managed by Mälardalen University and provides physical servers for networking students. The comparison is based on three aspects, performance, limitations, and usability. To fulfill the aim, three research questions were formulated. The first examines what one tool can accomplish that the other cannot. The second focuses on performance by analyzing execution time as well as CPU and RAM usage. The third research question evaluates the usability of each tool. The implementation consisted of three tests for each tool, representing different automation scenarios. The results showed that Terraform had the fastest execution time and offered more functionality, while Ansible demonstrated lower CPU and RAM usage. Based on the comparison, it can be concluded that Terraform is the more suitable automation tool for creating and managing virtual machines on Netcenter’s Proxmox servers
OMVÅRDNAD UNDER COVID-19 pandemin : En allmän litteraturöversikt ur ett sjuksköterskeperspektiv
No full textDigitala strategier för ökat engagemang i cirkulär konsumtion : En fallstudie angående ReTuna återbruksgalleria
No full textAbstract: The transition to a circular economy requires new ways of engaging consumers in reuse and sustainable consumption. Digital solutions have the potential to support this transition by influencing motivation, engagement, and behavior. The aim of this study is to examine how three digital prototype scenarios (gamification, transparency, and convenience) are perceived by users in relation to engagement in circular consumption within the context of the ReTuna reuse mall. The study was conducted as a qualitative case study with quantitative elements. Data collection consisted of user tests with semi-structured interviews conducted on-site at ReTuna, complemented by a digital survey distributed via ReTuna´s social media channels. Respondents were asked to evaluate three designed prototypes representing different digital strategies related to reuse. The collected data were analyzed using thematic analysis. The results indicate that gamification was perceived as the most motivating strategy by the majority of respondents, particularly through rewards and tangible incentives. Transparency was experienced as meaningful and value-creating, especially among respondents with an existing interest in environmental issues, while convenience was mainly associated with improved user experience rather than increased motivation to contribute. The study provides insights into how digital solutions can be designed to enhance engagement in circular consumption and offers practical implications for the development of digital services within reuse-based organizations.

Foreign Language Classroom Anxiety in the Swedish EFL Upper Secondary Classroom : Upper secondary English teachers’ stated beliefs and experiences
No full textThis study sets out to explore the perception of qualified Swedish upper secondary English teachers’ stated beliefs and experiences in relation to foreign language classroom anxiety (FLCA), and their implementation of teaching in relation to FLCA. For this study 6 teachers from across Sweden were approached through qualitative semi-structured interviews whose responses were then analyzed with thematic analysis. Through the analysis 7 themes were constructed in accordance with the participating teachers’ stated beliefs and experiences. The study found several classroom situations to be anxiety-inducing in relation to students’ performance and participation in the classroom. Students’ self-perception and level of proficiency were identified as significant sources for FLCA, according to the participating teachers. In an effort to alleviate students’ FLCA, the teachers attempted at creating a safe classroom environment and implementation of solutions such as pair and group work.
Formal and dynamic equivalence : a comparative corpus study of two modern English versions of the Gospel of John
No full textBible translation can be based on a spectrum of approaches between formal and dynamic equivalence. This study will compare two currently popular English Bible translations, the New International Reader’s Version and the New American Standard Bible, and analyze how they reflect these translation approaches linguistically. This study employed a corpus analysis of the Gospel of John, utilizing frequency analysis, keyword analysis, KWIC analysis, and n-gram analysis. The results reveal that the New International Reader’s Version prioritizes unambiguous, contemporary, and relatively informal terms along with simpler syntax compared to the New American Standard Bible. Some of these simplifications result in a loss of meaning in theological doctrine.
Peroncentrerad vård : En allmän litteraturöversikt av sjuksköterskors erfarenheter
No full textBakgrund: Personcentrerad vård är centralt för att skapa trygghet, delaktighet och välbefinnande hos patienter och anhöriga. Sjuksköterskor har enligt lagar och riktlinjer ett ansvar att utforma vården i samverkan med patienter och anhöriga utifrån deras behov och resurser. Syfte: Syftet var att beskriva sjuksköterskors erfarenheter av personcentrerad vård. Metod: En allmän litteraturöversikt enligt Friberg (2022a) genomfördes där åtta kvalitativa och två kvantitativa artiklar analyserades. Resultat: Det framkom fyra teman utifrån kärnfynd, vårdrelationens betydelse, partnerskapets betydelse, kommunikationens betydelse samt vårdmiljöns betydelse. Sjuksköterskors erfarenheter var att personcentrerad vård förutsatte en vårdrelation präglad av närvaro och empati. Partnerskapet stärkte patienters och anhörigas delaktighet genom hela vårdprocessen. Kommunikationen möjliggjorde informationsutbyte mellan sjuksköterskor, patienter och anhöriga för att främja personcentrerad vård. Samtidigt framkom hinder i vårdmiljön som tidspress och hög arbetsbelastning som försvårade personcentrerad vård. Slutsats: Olika aspekter påverkar sjuksköterskors erfarenheter av personcentrerad vård. Det är viktigt att sjuksköterskor ges rätt förutsättningar för att kunna bedriva personcentrerad vård enligt dem lagar och styrdokument som finns
Från lågstadiet till mellanstadiet : En studie om överlämnandet av elever i läs- och skrivsvårigheter från årskurs 3 till årskurs 4
No full textVår studie undersökte hur mottagande enhet på mellanstadiet beskrev överlämnandet från årskurs 3 till årskurs 4 gällande elever i läs- och skrivsvårigheter. Resultaten visade att överlämningarna inte var likvärdiga, genom att informationen om eleverna som befann sig i läs- och skrivsvårigheter skiljde sig åt. Alla respondenter efterfrågade eller lyfte vikten av detaljrika innehåll gällande vilka svårigheter det handlade om, hur långt eleverna hade kommit i sin utveckling samt på vilket sätt undervisningen hade utformats för att möta behovet hos elever som befann sig i läs- och skrivsvårigheter. Vidare framkom det att kompetensen hos både avlämnande och mottagande enhet var en nyckelroll i hur detaljrikt överlämnandet var. Speciallärarens roll belystes som oerhört viktig med sin spetskompetens gällande läs- och skrivsvårigheter, och var hyllad där speciallärare fanns att tillgå, samt saknad och efterfrågad där speciallärare saknades
On the Design and Analysis of Electrified Aero-engine Families
No full textRather than designing a new engine from scratch for every aircraft application, manufacturers often develop families of engines that share a common core; typically comprising the high-pressure compressor, combustor, and high-pressure turbine. This strategy reduces cost, shortens development time, and mitigates technical risk, making it an attractive option in today’s evolving aerospace landscape. Common-core variants are always associated with performance penalties compared to individually optimized clean-sheet engines because the initial core design is compromised to allow for adjustment of its component map entry points, but there is a high potential for better economics of the entire engine program. To address these challenges, this thesis introduces a simulation methodology for assessing both conventional and electrified aero-engine architectures, including turbofans, turboprops, and distributed electric propulsion systems. Based on a multi-point synthesis approach, the framework supports performance evaluation across multiple fidelity levels: from 0D thermodynamic cycle modeling, to 1D mean-line design, and up to 2D throughflow component analysis.A particular focus is placed on electrically driven propulsors, evaluated both as standalone units and within turbo-electric configurations. These include variants featuring variable geometry, such as variable pitch fans and variable area nozzles, when necessary. Building on the standalone engine modeling foundation, a novel methodology is introduced for simulating common-core engine variants within an aero-engine family. This extends the multi-point synthesis approach by treating the design point of each variant as an additional off-design condition of the baseline (first-to-enter-the-market) engine. To demonstrate its application, an electrified turboprop engine family is designed and analyzed across a range of power growth scenarios. Clean-sheet engine designs are developed in parallel to serve as benchmarks, enabling quantification of the performance penalties associated with enforcing commonality across various levels of power growth
Exploring the Dynamics of Customer Satisfaction : - the Emerging Role of Perceived Sustainability
No full textExploring the Dynamics of Customer Satisfaction – the Emerging Role of Perceived Sustainability, aims to advance the understanding of the dynamics of customer satisfaction by examining both its drivers and the use of customer satisfaction measures. This thesis describes the user-based quality management perspective and the emergence of customer satisfaction measures. Customer satisfaction is highlighted as a key organizational indicator, showing a positive relationship with financial indicators, and the ability to facilitate value in use. The use of both customer satisfaction, and the user-based perspective, in fields such as quality management and innovation, is also described. Sustainability is further highlighted as a concept to which the user-based perspective could be extended. Thus, potentially transforming organizational sustainability initiatives from a regulatory obligation, a license to produce, into a driver of customer satisfaction, and a source of competitive advantage. Using both qualitative and quantitative data, this thesis explores customer satisfaction models’ drivers, examined the use of customer satisfaction measurements, investigated how an extended customer satisfaction model may be established, and to what extent the model is influenced by adding a construct of perceived sustainability. Both data and structural customer satisfaction model are appended from the Nordic market research agency EPSI Rating. Estimation of customer satisfaction drivers is mainly performed by using the Partial Least Squares Path Modelling technique. The findings show how a construct of perceived sustainability may be developed and add empirical data exploring the drivers of customer satisfaction. A customer satisfaction model is further evaluated by adding the developed construct of perceived sustainability, showing favourable fit and increased predictive power in the manifest customer satisfaction items. Especially regarding items considering the customer’s view of an ideal actor. Insights about how organizations may utilize measures based on customer perceptions are also discussed. Further highlighting the importance of focusing on the recipient’s needs and wants when planning to engage in measuring customer satisfaction. For scholars, this thesis shows how a construct of perceived sustainability may be developed and add empirical data clarifying the drivers of customer satisfaction. This thesis also shows how customer satisfaction measures are being applied in practice and the importance of considering all direct and indirect interactions within the customer experience. Simply stated, the importance of considering the dynamics of customer satisfaction. For practitioners, this thesis provides insights about how organizations can enhance customer satisfaction and shows that sustainability, when analysed as a part of the customer experience, may be transformed from a strict regulatory obligation, into a source of competitive advantage. Future research is suggested to examine how the results of this thesis could be enhanced by adding a time perspective and how the results could be applied in different fields of research. For example, as tools to examine market disruptions. New ways to estimate drivers of customer satisfaction are further suggested to advance the understanding of the customer experience and to extend the findings of this thesis
