Utvärdering av protesfötter med hjälp av en konstruktion som kan utföra en mekanisk gång.

This paper has evaluated a new type of prosthetic foot, X-Balance, which aim was to facilitate the performance on uneven ground for the user. This study have performed gait analyzes with three prosthetic feet, the X-Balance, Flex-Foot and assure Ottobock9192 on flat and uneven surfaces using 3D analysis system QTM (Qualisys Track Manager) and associated force plates. During the project a prototype of a design that can perform a mechanical gait were manufactured. The prototype has then been used to fulfill the purpose and objective of this study which is to make different final sets that demonstrate differences between prosthetic feet. Gait analyses of individuals have also been performed to get an idea of what normal gait is.

Miljöcertifieringssystemet Miljöbyggnad : Inverkan på utformningen av ett kontor

The use and attention given to the certification system ?Miljöbyggnad? has increasedin recent years. The system is completely Swedish and was initiated in 2005 by theBygga-Bo-Dialogen. Miljöbyggnad aims to create a healthy indoor environment, reduceenergy consumption and discourage the use of hazardous chemical substances. Thegrades that can be obtained are Classified, Brons, Silver and finally Gold.The work has been to examine three different models and conclude how the designof the models affect the grades in the certification system Miljöbyggnad.

Utvärdering och implementering av automatiska farthållare i fordonssimulator

Vehicle simulators are becoming more common in vehicle industries. Company earns lot of money on simulations instead of real tests. Real tests are necessary but not made so extensively as before.In this thesis the building of an vehice simulator will be described and a Comparison between three different cruise controls. The three cruise controls are PI-regulator, a regulator who regulates after positions in the terrain and a MPC-regulator. The reason for choosing this three is to see the difference between simple regulation and more complex regulation with respect to fuel consumption, travel time and complexity.The vehicle simulator is made in Matlab/Simulink, Visual Studio and Open Scene Graph.

Strömningen i och över en skog : utvärdering av en 'mixing-layer' hypotes

A new theory for predicting the windprofile over a canopy has been evaluated. The theory was first presented by Harman and Finnigan (2007). The theory relies on the forming of a mixing-layer above the canopy, due to different mean wind in and above the canopy. Characteristics from both mixing-layer and Monin Obukhov similarity theory have been used to develop the governingequations that give the wind profile. The theory has been used to calculate wind profiles for sixdifferent atmospheric stabilities.

Insatsen kontaktperson för ungdomar mellan 13-18 år : en rättssociologisk studie

The purpose of this essay was to study which arguments social workers used in the basis of their estimation concerning young people of the age 13-18 given an aid, a contact person (swe. kontaktperson). The purpose was also to describe how the legal paragraph, regarding contact person, is regulated and then compare the arguments made by the social worker with the intentions expressed by the legislator. To answer our purposes we studied the law and the intentions expressed by the legislator, which is the foundation for the legal paragraph that regulates contact person, 3 chap. 6 §.

Framgångsrik Implementation av Lean : Förbättrade möjligheter med implementationsmodell

Lean production is the name given to Toyota?s Production System (TPS) by the west. The continuous improvements of their operations through Lean has made Toyota into the largest car manufacturer in the world. This, in turn, has led to several studies regarding both Toyota and their system as to find ways to apply Lean in other organizations. Even so, over 90 percent of all companies fail to implement Lean.

Solel och solvärme ur LCC-perspektiv för ett passiv-flerbostadshus

This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical Comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.

Seriell återgivning av två-röstslistor: ord organiseras inte efter röst

AbstractTitle: Serial recall of two-voice lists: Words are not perceptually organized by voice.The present study examined how voice affects the perceptual grouping of words in short-term memory that are auditory presented. Three different voice-lists were used: single-voice, alternating-voice and split-voice. In single-voice lists all words were presented in the same voice. In alternating-voice lists words were presented alternately in a male and a female voice. Finally, in split-voice lists words were presented grouped four and four in a male and a female voice.

Att skapa en snabb, sökdriven e-handelssajt : en studie med backend-lösningar i fokus

AbstractThis study examines the technologies appropriate in developing back-and solutions for search-driven user interfaces of e-commerce sites. The study is based on existing research in search-driven user interfaces of e-commerce sites from a design point of view, but instead the focus of this study lies within a back-end perspective. This choice of focus is a result of the gap that was encountered within research and other literature when it comes to general advice in how e-commerce sites best should build back-end solutions to support search driven user interfaces. The technologies that have been examined and compared are traditional relational databse management systems (RDMS) and the newer so called No-SQL database management systems, and also traditional search engines and the newer variant s of search engines. The study concludes that in some cases it is appropriate to combine traditional and newer technologies when it comes to databases, while the Comparison of search engines indicates that there are some newer search en gines that have the ability to meet more of the needs that can be identified on the back-end solutions.Primary data consists of interviews made ?face to face? with experts on the subject and questionnaires addressed to selected e-commerce companies via e-mail.

Välfärd i ekologisk och konventionell grishållning :

Organic animal husbandry has received a lot of criticism lately. The aim of this literature review was to examine if the rules and principles of organic pig farming give better or worse welfare in Comparison to the conventional systems in Sweden. Health, physiology and behaviour have been used as indicators of welfare in this study. This is due to the importance of using more than one indicator in welfare assessments. Studies have shown that organic pigs have more remarks on joints when slaughtered, but these remarks can be reduced by vaccination against erysipelas.
