Shopping Cart Support
This is a product development project which has developed a prototype in order to facilitate for people using mobility devices when they want to buy a larger quantity of groceries. The prototype is a shopping cart composed with the upper part of a walker.Today there are many different types of mobility devices used by elderly and people with physical impairment. According to Myndigheten för samhällsskydd och beredskap (MSB) are accidental falls the most common cause of accidents in Sweden.This project has been using Computer Aided Design (CAD) as a tool to create a visual image of the prototype. The advantage of this is to modify the functionality and performance of the prototype on the computer before the modification takes place in the real model. Using human manikins, the CAD model was rendered in natural surroundings to get as true a picture as possible.
Hur skiljer sig tjockleken på retinas nervfiberlager mellan emmetroper, myoper samt hyperoper? : En OCT studie
Syfte: Syftet med studien var att utreda sambandet mellan ögats ametropi och tjockleken på retinas nervfiberlager (RNFL) med optical coherence tomography teknik (OCT).Metod: I studien ingick 30 försökspersoner med olika typ av ametropi. En inledande mätning med autorefraktor genomfördes och styrkorna värderades därefter av i provbåge. På så sätt erhölls ett resultat på storleken på den eventuella ametropin. Därefter utfördes den huvudsakliga mätningen av nervfiberlagets tjocklek med OCT kameran OPKO Spectral OCT Slo på samtliga försökspersoners högerögon. Försökspersonerna delades in i fem olika grupper utifrån befintlig ametropi.Resultat: En signifikant korrelation mellan ögats ametropi och det retinala nervfiberlagrets tjocklek hittades då resultaten från alla 30 försökspersoner analyserades mot varandra.

Optimering av slutfasstyrning
Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.
Microstrip Solutions for Innovative Microwave Feed Systems
This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.
