Innovativt Drivpaket för Rullstol

This is a thesis for a Bachelor Degree Project, performed in the subject MechanicalEngineering. The students Roger Malmberg and Simon Hagberg have carried out adesign project on behalf of the recently established company J&D Assisting systems,located in Halmstad.The project consisted in developing J&D's first prototype of a power assisting solutionfor wheelchairs. A power assisted wheelchair combines human power, which is deliveredby the arms through the pushrims, with electrical motors, which are powered by a battery.The power assisted wheelchair is aimed at customers, who have used a regularwheelchair for a long time, but who have become weaker or just need additional powerwhen driving uphill. This kind of wheelchair will provide additional power for users,which will spare their wrists, elbow and shoulders. The product is torque sensor free andinstead it relies on the velocity.

Xlight-Retro : En lampa för offentliga inomhusmiljöer

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

Vem bestämmer över kvaliteten? : Bibliotekariers privata och professionella syn på kvalitativ skönlitteratur

With an increased empowerment of the users, and a dependence on outside critics, one wonders what kind of role the librarians have in a context where qualitative literature is discussed. The aim of this study is to examine the relationship between librarians private and professional views on qualitative fiction, in order to be able to discuss their role as quality intermediaries in a user oriented context.The method used, is the qualitative, semistructured interview. This author interviewed seven librarians from three different libraries in Sweden. The theoretical emphasis partly relies on the ten words of qualitative value that Inger Elam and Bengt Brülde discusses in their respective texts, partly on David Garvins quality assessment theory, which defines several quality categories divided between an absolute and a relative quality view.Through the comparison between the private and the professional quality view, examined with the two theoretical approaches, the analysis of the interview material shows that there lies a complexity in the librarians professional role. On the one hand, they are dependent of both the users and the critics judgements about the qualitative aspect in the work with purchasing new literature to the library.

Den fysiska miljön och skapandet av tjänstekvalitet hos frisörföretag

This paper exemplifies how the physical environment affects clients? experienced service quality and how companies work with the physical environment.

Owners of hairdressing saloons perceive that a combination of the personal meeting and the physical environment influence the clients? general impression and their experience of quality.

The empirical data consisted of five interviews with PR-consultants on five different PR-agencies. The theoretical framework was based on a social constructional perspective and Foucault?s theory of power.

Livskvalitet hos personer som genomgått en total höftledsplastik - en litteraturstudie

The purpose of the study was based on scientific literature to describe the quality of life of persons who have undergone a total hip replacement. The method was a descriptive literature review.

But despite less pain were experienced early, it took 1 year to achieve the full benefits of improved physical function.

Åtråvärda objekt : En gestaltning av troféns materialitet

This thesis revolves around my work Desirable Objects, an installation in glass and other materials, which deals with objectification based on female and animal trophies. The topics included are those that have been crucial to my working process; craft, post-colonial studies and European hierarchical dualism, where woman and nature are seen as connected, but inferior. My motivation has been to get a better understanding of underlying power structures, and put this knowledge in relation to my own work. This process has led me to make a full body casting of my own body as a method of self-exploitation, in an attempt to expose myself to a similar power perspective. By making the dualistic connection between woman and nature, I am commenting a phenomenon that in my view has resulted in a similar exploitation of both..

Visuell presentation i slöjd : Positivt med power point?

Detta arbete undersöker problematiken i att visuellt framföra och presentera ett arbetsområde i ämnet träslöjd. Uppsatsen handlar även om och hur slöjdlärare kan undvika onödig stress. Syftet med uppsatsen är att undersöka hur man i träslöjd kan utvidga sättet att presentera uppgifter för eleverna på ett inspirerande, innehållsrikt och konkret sätt. Genom att bedriva en praktisk visuell presentation i form av Power Point har jag fått en uppfattning om ett alternativ till den traditionella undervisningsformen i träslöjd. En utvärdering gjordes med eleverna efter Power Point presentationen och den visade bland annat att eleverna i år 4 fick mer utbyte av uppgiften jämfört med år 5-6.

Kvalitetssäkring vid en monteringslina : ett projekt på Swepart i Liatorp

För att Swepart Transmission AB ska fortsätta att hålla en hög standard på produkter som levereras till kunder, ska monteringslinan för Power Take-Off säkras. Budgeten som är avsatt till att kvalitetssäkra monteringslinan är 500 000 kr. Pick-to-Light och Pick-to-Voice är system som kan användas för att kvalitetssäkra monteringen av Power Take-Off. Systemen jämfördes med systemet med monteringskort som används i nuläget. Det mest lämpliga att införa har visat sig vara Pick-to-Light.I samband med införandet av detta system måste utredningar göras för vilka komponenter som behöver sensorer och vilka som kan säkras på andra sätt.

Programvaruapplikation som stöd vid granskning i Dimensions

AbstractThe control of quality standard ISO 9001 has made the internal audit to be experienced as police authority and paragraph control. Because of that, motivation for internal auditors is low. To counteract the experience, there is a possibility to integrate internal audit with improvements in company?s processes. Theory has shown that a qualified and competent auditor can provide information that can help the organization's managements to make the right decisions that will improve product quality and result in new customer contracts.An opportunity to observe an internal and external audit at one of the case companies gave rise to this study.

Bakom de goda intentionerna: en intersektionell analys av hur "vi" och "dom" reproduceras och kategoriseras via politik och massmedia.

The purpose with this essay is to look at how categories of "us" and "them" are created, reproduced and categorised. The areas of politics and media are in focus, though they are powerful and influential actors in generating discourses.The method is qualitative analyses of current research and analyses of discourses, contexts and resources from an intersectional perspective. Intersectionality presents a theoretical tool for complex understandings of power as it takes its point of departure in an understanding of power as multidimensional and one where gender, ethnicity and class are constitutive and bearing principals. Intersectional analyses aim to understand how these dimensions are created and changed in relation to each other and how they interact with specific gender orders in specific contexts.The analyse shows that "immigrants" are in a subordinate position compared to "Swedish" when it comes to resources, contexts and discourses. The analyse indicates the relation of power between "us" and "them", where "us" have the power and with that preferential right of interpretation in discourses, contexts and resources.
