Användarens perspektiv sätts i fokus hur den kan tänkas betrakta och uppfatta maskinen genom instruktionerna i animeringen.

Syfte: Syftet var att ta reda på vilken metod som är lämpligast att använda för synfältsundersökning vid ett körkortstest hos optiker samt vilken metod det är vanligast att optiker i Sverige använder idag. Dessutom var syftet att utreda varför optiker inte får använda konfrontationstest då det är den metod läkare ska använda för synfältsundersökning enligt körkortsföreskrifterna.Metod: En enkätundersökning med 275 deltagande optiker gjordes. De fick besvara ett fåtal frågor kring vilken metod de använder när de undersöker synfältet vid ett körkortstest samt deras kunskap och inställning till bestämmelserna kring vilken metod som skall användas utav optiker och läkare. Enkätundersökningen publicerades med web-enkätprogrammet Easy Survey.Resultat: Enkätundersökningen visade att endast 58,5 % av optiker i Sverige använder sig av den speciellt avsedda apparaturen. 34,9 % av deltagarna svarade att de använde sig av Donders konfrontationstest.

This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.

The main purpose of this study was to investigate in what manner librarians and pedagogues can cooperate in order to help students with reading and writing problems and consequently enhance their information literacy. I aimed to investigate why cooperation between these professions is necessary. Also, I wanted to find out how the general support is on the schools regarding students with reading and writing difficulties, and if the school librarian knows what the special educator can contribute with and vice versa. Lastly, I focused on what knowledge the performers of these professions have about reading and writing difficulties and to what degree their knowledge is based on scientifically proven methods.The two theoretical points of departure are 1) theory of cooperation built upon Louise Limberg?s and Lena Folkesson?s three categories of cooperation 2) and Aidan Chambers?s reading promoting model named the circle of reading.

The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.

This master?s thesis investigates the technology and security awareness associated with wireless networks (WLAN). It has been stated by the media and theories that many wireless networks are unprotected. This has sparked an interest to investigate the phenomenon in the Jonkoping region. The study is based on the following research questions:- What security weaknesses are present with the WLAN-technology and how can these be avoided?- How does the wireless infrastructure in the Jonkoping region look like?- Why do companies implement the WLAN-technology?- Are the companies aware of the risks involved with WLAN?We conducted this study in three steps; the first step was to hack a wireless network in a controlled environment in order to investigate the weaknesses of the commonly used security measures.

A Queer Reading of Charles Bukowski?s Women and Love is a dog from hellThis thesis aims to examine how the representation of gender is portrayed in relation to sex and power in Charles Bukowski?s novel Women and poetry collection Love is a dog from hell.The theoretical frame of the analysis is based on Judith Butler?s queer theory regarding the heterosexual matrix and gender performativity. The analysis consists of a textual comparison where a specific selection of poems is analysed parallel to the novel to see how they interact and how they oppose each other, through a queer reading.The analysis is divided in three parts where the first one discusses the construction of masculinity in Charles Bukowski?s protagonist Henry Chinaski and how this is presented differently in the two literary genres. The second part reveals how sex is presented in relation to power and how active and passive women are considered as sexually acceptable.

Today it becomes more and more important to work with continuous improvements to stay ahead of the competitors. Pfizer in Strängsäs started working with continuous improvements in 2010. By the end of 2012, the company?s goal is to reach 24 improvements per employee at the factory.Their project has two main purposes; to examine the need and possibilities for visualization regarding continuous improvements at the production department and to develop a concept for visualisation of the entire factory?s continuous improvements.To attain the information required to examine the needs at the production department, interviews with relevant employees at the department were conducted. Using interviews as a benchmarking instrument was also helpful in getting different points of views.

The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security. In order to study usability, a test group of ten persons have been used to evaluate the usability of the system.

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.

Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application. When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation. The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions. Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense. Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials. This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating. Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films. Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..

This master thesis is commissioned by Permobil AB. The report describes thoroughly the developing process of an adjustable backrest for wheelchairs. The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.

Reinforcement is of great importance to fulfill the dimensioned strength of a concrete construction. This requires that the work needs to be carried out with adequate results that neither endangers the workers or the safety of the construction. Progressive development of the planning phase, construction documents, and construction methods is in constant need since the technology constantly evolves.In order for contractors to be able to get acceptances from their quotations requires that they have to increase their working pace in order to be able to leave a quotation with a lower price than the competition.Due to the increasing pace the different parts involved in the construction process is subjected to time pressure. The design stage, construction documents, work preparation and the execution are all affected when everything has to be finished quickly. To avoid problems, it is required that all parts are able to deliver good quality solutions and results under the influences of time pressure, which is not always easy.

Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.
