Missilstyrning med Model Predictive Control

This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.

Musik och rörelse som vägledningsmetod för ungdomar med ADHD/DAMP

Denna uppsats handlar om musik och rörelse skulle kunna vara en alternativ vägledningsmetod vid studievägledning för ungdomar med diagnosen ADHD/DAMP. Uppsatsskrivarnas huvudsyfte var att undersöka om musik och rörelse skulle kunna användas inom vägledning för att ge dessa ungdomar större möjligheter till ett mer kvalitativt underbyggt val till vidare studier. Undersökningen bygger på kvalitativa metoder genom intervjuer med studievägledare inom grundskola samt en aktiv studievägledare (verksam med ADHD-elever). Vi har också intervjuat en Tomatis terapeut (En metod som tränar hjärnan att prioritera, sortera och hantera sinnesintryck bättre) samt en användare av metoden. Resultaten vi kom fram till var att Tomatismetoden resulterade i stora förbättringar gällande koncentration och uppmärksamhet, samt att kvarvarande effekter bestod i minst sex månader.

Mikrosimulering för analys av Mästergatans förlängning i Enköping

Two of the main approach roads into the city of Enköping are Salavägen and Stockholmsvägen. They are connected to each other through the street Bangårdsgatan in the roundabout Salatullen and crossing Fannakorset, respectively. These crossings are from time to time heavily loaded, which is why the municipality plan for a new street in parallel to Bangårdsgatan. The traffic will then be spread out and is thereby reducing the density. The new street is actually an extension of the existing Mästergatan, a side street to Salavägen, to the east and connecting it to Stockholmsvägen or a street nearby.The purpose of this Master thesis is to show how the new street can be drawn in order to discharge the traffic in the area between the roundabout Salatullen and the crossing Fannakorset.

Positionering i små nischade detaljhandelsföretag inom klädbranschen

The purpose of this thesis was to illuminate and create a deeper understanding of how small niche retail businesses within the apparel industry position themselves. We aimed to investi-gate how these small niche retail businesses create their position and how they communicate these positions to their target market. To be able to investigate the positioning-process within these small niche retail businesses a case study was conducted based on interviews with two respondents from two different companies and observations of these businesses physical envi-ronments. The study indicated that the small niche retail businesses mainly make use of emo-tional aspects and their assortment range to create their position. To communicate their posi-tion to their target market they mainly use their in-store personal selling and their assortment range..

FAKTORER BAKOM M?GELTILLV?XT P? N??S SLOTT

With climate change, the temperature and relative humidity in Sweden are increasing. The majority of historical environments lack protection against this increase, which also increases the risk of mold infestation in these environments. One of these environments is N??s Slott, in which several rooms have recurring mold growth on objects and furniture. By examining one of the rooms in the castle that is in the risk zone or has mold growth, factors behind the mold growth can be investigated in order to create a basis for future actions against mold.

Cissus Quadrangularis Linn

The aims of the study were to investigate the prevalence and antibiotic resistance of Campylobacter jejuni and Campylobacter coli in chicken and chicken products, and to investigate farmer awareness of antibiotic resistance development. The study was conducted in the Can Tho province in Vietnam during six weeks in October to November 2008. Ninety-six samples from raw chickens were collected from twelve market places and analysed for the presence of Campylobacter. A total of 96 cloacal swabs from 20 farms were obtained and analysed for the presence of Campylobacter. Farmers were asked to answer eight questions concerning the housing of the chickens, modes of handling sick animals as well as use and knowledge of antibiotics and resistance development to antibiotics.

Journalsystemet TakeCare : En studie av funktioner utifrån ett informationssäkerhets- och användarperspektiv

Sedan införandet av datoriserade patientjournalsystem och sammanhållen journalföring har det riktats kritik mot hälso- och sjukvårdens hantering av patientinformation. Det råder delade meningar om det är användare eller systemen som felar. Syftet med undersökningen är att inspektera utvalda funktioner i journalsystemet TakeCare som utvecklats för att upprätthålla patient- och informationssäkerhet. Genom att jämföra funktionerna med Socialstyrelsens uppsatta informationssäkerhetskrav har uppsatsen som mål att hitta var de påtalade problemen kan uppstå. Genom att fråga användare kring deras uppfattning om systemet är avsikten att få en förståelse av om problemet ligger i de tekniska funktionerna eller i hanteringen av systemet.Metoder som använts under arbetet är e-postintervjuer och ett studiebesök på Stockholms läns landstings IT-avdelning i form av en intervju och presentation av TakeCare.Vi har sett att det finns funktioner som tar hänsyn till samtliga informationssäkerhetskrav samt att användarna anser att de kan hantera systemet, men trots det kritiseras informationshanteringen inom sjukvården.

Kortsiktig fosforeffekt av avloppsslam : krukförsök i växthus där järn-, aluminium- respektive kalkfällt slam använts som fosforgödselmedel

The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.

Dammsugare att motivera till dammsugning

How can a vacuum cleaner motivate you to use it? From a sustainability perspective,the author asked the question of how such a solution would looklike? These where issues that the project tackled and devised solutions for. Theproject wanted to explore the physical modeling and a large part of the finalresult consisted of a full scale model. The project found that the problem ofvacuuming largely consisted of the problem of storage the product. The projectfound that the motivation for the job, therefore, could be resolved by a betterdesigned vacuum cleaner with a built-in hose, folding handles, which couldbe stored integrated within the vacuum cleaner.

Aktiv lastbilsstol för bättre förarergonomi och hälsa

The project concerns a predevelopment work for Scania AB, a leading manufacturer of heavytrucks, and was performed as a master thesis work for the program Design and ProductDevelopment at KTH. The purpose of this work was to examine how the work situation of truckdrivers, especially long-haulage drivers, can be improved with respect to prolonged sedentaryoccupation. Mental fatigue and under-stimulation due to low cognitive load during long drivescan be major risk factors for traffic accidents. Physical strain injuries to both the skeleton andmuscles are common for this working group and minimal opportunity for daily exercise alsoincreases the risk of developing blood clots in the legs, which can have serious consequences forthe driver's health.An extensive background study, both theoretical and exploratory, was performed to identify thedrivers' concerns and comfort needs. Various treatments such as massage and active sitting wereinvestigated and existing products within the area studied.
