“To be, or not to be” surely constitutes a strange walk on the tight rope between delusion and reality, and apparently, Robert Fleming is a man with immense problems. Who is Ziggy Stardust, and who is Stephen Dedalus? Is it relevant to claim that there is more of David Bowie’s true personality inside Ziggy than of, for instance Charles Dickens’ great expectations within Pip? By examining Nick Hornby’s novel High Fidelity and it’s main character from a Freudian perspective using Freud’s theories and ideas of the oedipal concept, this is basically a plain attempt in search for a better psychological knowledge and understanding of the musical world of illusion, which finally ends up in a serious effort to interpret the true and inner meanings of Rob’s dreams and personality.

There are a vast number of research and studies undertaken within the domain of user-centered design concerning the design process of an artifact, but still there are questions being raised of the relatively new and successful field of mobile design. During recent years mobile technology have surpassed the standardized thoughts of how to prototype and evaluate such a ubiquitous device. The paper addresses this predicament by discussing aspects of fidelity differences in an early design process of a mobile design. The example being presented refers to a design study of an iPhone-application, where two different types of prototypes were created and user tested, a low-fidelity paper prototype and a mixed-fidelity interactive prototype. The paper sets focus on the various differences between these fidelities closely related to the case. It also reflects on how mobile design approaches can mature during the early stages of a design process.

Detta examensarbete är genomfört i samarbete med Thorbjörn Birging. Birging arbetar med RFID[1] och är även VD för CombiQ på Science Park i Jönköping. Under lång tid har han velat skapa en produkt som hjälper människor med sömnproblem, depression, ångest och stress. Författarens roll som ingenjörsstudent blev att utveckla hans ide till en färdig produkt. Birging upptäckte efter att ha läst en artikel om sömnproblem att det finns studier som visar att det är enklare att somna med ett svagt ljud i rummet för att andra personer i rummet inte skall störas. Birging fokuserade på att skapa en ny ljudkudde med denna teori som grund.  Målet med detta examensarbete blev att skapa en kudde med fokus på utmärkt stereoljud som hjälpredskap för människor med sömnproblem. Med ljudets användning blir insomningen betydligt lättare. Många människor söker hjälp för sina problem på sjukhus, men ofta får de bara recept på lugnande och antidepressiva mediciner. Ett annat problem med sömntabletter är risken för att utveckla ett beroende och en längre tids användning av medicinerna kan störa kroppens normala sömnfunktion, vilket läkaren Anders Isaksson som driver en privatklinik i Örebro kan intyga. Birging har haft kontakt med Anders under detta arbete och kan intyga detta.  Ett sätt att lindra sömnproblem är genom att patienten får lyssna till lugnande musik före insomnandet, vilket alltså är tanken med denna kudde. Författaren genomförde en undersökning för att ta reda på vad som är bra och dåligt med dagens ljudkuddar. En idégenerering och kravspecifikation påbörjades med hjälp av Birging. För att kunna veta vad kunderna önskar sig med denna nya produkt gjordes bland annat en designbrief, funktionsanalys och en QFD-matris. Designbriefen skapades både verbalt och visuellt för att se hur den nya produkten skall se ut på markanden. QFD-matrisen rangordnar kraven och konkurrenternas kuddar i förhållande till Birgings krav på den nya prototypen. QFD ger inte svar på vad kunden får för upplevelse med produkten vilket designbriefen kan åstadkomma. Konstruerandet av prototypen kan börja först när designbriefen och funktionsanalysen är klara. Materialvalet gjordes genom testfaser som ljudåtergivning och komfort. Skumplast materialen kommer ifrån Recticel AB i Gislaved och ett intresse för denna nya produkt finns i den framtida utvecklingen.  Denna nya produkt blev betydligt bättre än de ljudkuddar som finns på marknaden. Den nya produkten har egenskaper som tryckavlastning samt bättre ljudkvalitet vilket innebär att volymen inte behöver vara hög, vilket gör att omgivningen inte störs. Orsaken till att ljudet inte stör är att spridningen av ljudet mestadels riktas upp mot användaren. Kuddens mått är B50*H40*T5 cm innebär att man enkelt kan köpa vanliga örngott och att den inte ta onödig plats i sängen.

In this thesis, a novel approach is presented for blade loss simulation of an aircraft gas turbine rotor mounted on rolling element bearings with squeeze film dampers, seal rub and enclosed in a flexible housing. The modal truncation augmentation (MTA) method provides an efficient tool for modeling this large order system with localized nonlinearities in the ball bearings. The gas turbine engine, which is composed of the power turbine and gas generator rotors, is modeled with 38 lumped masses. A nonlinear angular contact bearing model is employed, which has ball and race degrees of freedom and uses a modified Hertzian contact force between the races and balls and for the seal rub. This combines a dry contact force and viscous damping force. A flexible housing with seal rub is also included whose modal description is imported from ANSYS. Prediction of the maximum contact load and the corresponding stress on an elliptical contact area between the races and balls is made during the blade loss simulations. A finite-element based squeeze film damper (SFD), which determines the pressure profile of the oil film and calculates damper forces for any type of whirl orbit is utilized in the simulation. The new approach is shown to provide efficient and accurate predictions of whirl amplitudes, maximum contact load and stress in the bearings, transmissibility, thermal growths, maximum and minimum damper pressures and the amount of unbalanced force for incipient oil film cavitation. It requires about 4 times less computational time than the traditional approaches and has an error of less than 5 %.

High-fidelity simulation (HFS) is a teaching innovation that is becoming a key component in nursing education programs. Nursing students are able to practice skills without fear of harm to themselves or to a patient, and nurse faculty can demonstrate techniques and critical scenarios in a way that may not be available to students or faculty in the clinical setting. However, nursing faculty are not utilizing this teaching innovation to its potential suggesting educational administrators could benefit from understanding the challenges that nurse faculty face when integrating HFS into their teaching practice. The purpose of this phenomenological study was to explore the lived experiences of nurse faculty who were required to integrate HFS into their teaching practice. In this study, seventeen female nurse faculty who taught in the second year of the Saskatchewan Collaborative Bachelor of Science in Nursing (SCBScN) at Saskatchewan Polytechnic Saskatoon Campus were interviewed about their experiences integrating HFS into their teaching practice. The transcripts were analyzed using Moustakas’ (1994) modified Van Kaam method. Six themes describing the essences of the participants’ experiences were identified: striving for self-efficacy, struggling to maintain autonomy, being part of a community of practice, adopting HFS as a teaching innovation, being an advocate, and being proud. An emerging theme, being an outsider, was discussed. An interpretation and synthesis of the results resulted in a conceptualization of the experience. This research has implications for integrating a new teaching innovation. The nurse faculty required support and resources, psychological safety while learning the new innovation, ongoing communication about the innovation, acknowledgement of their accomplishments, and a sense of pride in the institution. Recommendations for nurse faculty include becoming prepared, finding a mentor, participating in discussion forums, and advocating for time needed to learn. Recommendations for educational administrators include ensuring ongoing education and support, involving nurse faculty in discussions about the innovation from the beginning, providing a psychologically safe environment for learning, providing time to learn away from other teaching responsibilities, and fostering pride through acknowledgement of accomplishments.

Hospitalized patients increasingly present with complex health issues that place them at risk for acute patient deterioration (APD). Novice nurses are ill-equipped with the critical clinical skills to function competently in recognizing APD, placing patients at risk for negative health outcomes. This project addressed the need to educate novice nurses to recognize APD and answered the project focused questions that asked if an educational intervention with high-fidelity simulation (HFS) would improve nurse knowledge and clinical confidence in recognizing APD. Benner's novice-to-expert and the constructivism theory were used to guide the project. Based upon a review of the literature, the HFS was developed to provide scenarios in which participants would view APD evolving case studies and demonstrate knowledge and skill for caring for patients with APD. A convenience sample of 11 novice nurses participated in the pre- and posttest design project to determine if knowledge and clinical competence increased. Data from the HFS program were analyzed; results showed no statistically significant change in knowledge or confidence post intervention (p = 0.441). A larger sample size is recommended for future HFS interventions at the site to determine if the program of education will increase knowledge and clinical confidence with future iterations of HFS. The project has the potential to promote positive social change as novice nurses learn to recognize and respond to APD and as APD events are reduced.
