Medicinering vid sjukdomstillstånd i det främre segmentet av ögat hos häst är ofta tidskrävande och komplicerat för djurägaren. Syftet med studien var att undersöka om ett nytt tekniskt hjälpmedel, en spiral som kallas OphthaCoil, fungerar för långtidsmedicinering hos häst. Två olika designer på spiraler utvärderades. Efter en ögonundersökning placerades en spiral i nedre konjunktivalsäcken och hästen observerades till dess spiralen trillade ur. Resultaten visar att ingen av de använda designerna låg kvar tillräckligt länge för att kunna användas för en längre tids behandling.

This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.

We got in contact with Marco AB, who we?ve had contact with before concerning earlier projects, to find out if they were interested in arranging a larger project for our last class (Examensarbete 15hp). They were very positive to this proposition, and soon they offered us a project regarding reconstruction of their current mechanical device that absorbs all the force from the lift itself when it is at a predefined level (sv. sjunkspärr). The current solution does fulfill the requirements that are given, however it is not a solution that gives a high level of satisfactory.

Implementeringen av tablets ämnade för inspektioner inom drift och underhåll av vägar har studerats och utvärderats med målet att fördjupa kunskaperna inom drift- och underhållsbranschen och skapa effektivare arbetsmetoder som gynnar alla byggprocessens parter.  Examensarbetet är utfört hos Peab på deras anläggningskontor i Sundsvall och implementeringen har ägt rum på deras driftområde Sundsvall som består av cirka 122 mil statlig väg där Trafikverket är beställare. Genom litteraturstudier, tester av tableten och deltagande observationer så har tabletens användbarhet och utvecklingspotential analyserats och slutsatser har dragits för att ge Peab feedback på deras innovation med ett antal förbättringsförslag. Utvärderingen blev ej fullständig då Peab inte hann införa tabletsen inom vägdriften innan de 10 veckorna för examensarbetet var avslutade. Att använda tabletsen inom vägdriften kommer att effektivisera inspektionerna med dels digital dokumenthantering och det viktiga införande av GPS positionering  i de fordon som utför inspektionerna. Detta kommer bli mycket smidigare än den tidigare arbetsmetodiken där i stort sett alla processer innefattande mycket onödigt pappersarbete. Peab rekommenderas fortsätta att se utvecklingsmöjligheter med tabletsen inom andra områden av vägdriften samt fullfölja utvecklingen av tableten för att få en användbar produkt. .

Staff have to deal with a myriad of alarms and error codes in response to their patients varying ailments. The workforce at the dialysis ward lack controlled environment training, sufficient to address all of the potential treatment scenarios, with no risk of jeopardizing the patient?s condition.The purpose of this essay is to design and test the efficacy of using an IT based device for dialysis education at Karolinska University Hospital.The main topics this essay intends to address are:? Identification of user scenarios and training fields.? Prioritization of key training areas.? Utilization of IT in effective staff training.? Design of a conceptual prototype.The process focuses on the user and their needs.

Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

The project was intended to produce a brush simulation plugin to the image processing program GIMP which would use a 6DOF drawing tablet for user input.Too ambitious goals coupled with compability issues between the resources used resulted in that no meaningful software was produced. Experience was however obtained, and this paper is intended to give an overview of relevant concepts for- and the process ofcreating a brush simulation..

The purpose of the present study was to study if the systemic blood pressure in cats significant increases due to stress associated with a visit to a veterinarian clinic. We also wanted to investigate the clinical utility of two different methods for indirect blood pressure measurements in cats by assessing how easy they were to use and how reliable measurements they provided. The methods that were used were oscillometric (Memo Diagnostic) and ultrasound-doppler technique (Minidop). The blood pressure was measured in both clinical environment and home environment. Fifty cats were used in the study, from which measurements were impossible to obtain in one cat.

The purpose of this master thesis is to examine a proposal for basic class 4 in UDC, which has been empty since 1964, and to pick out a negotiable subject for that proposal. The proposal is analysed from a theoretical perspective based on principles created by S. R. Ranganathan. Three principles are used.

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Jag har studerat fenomenet Bring Your Own Device (BYOD) och hur detta har implementerats i svenska företag. Syftet har varit att beskriva vad BYOD kan innebära i olika verksamheter utifrån vad som kan anses inkluderat i trenden. Jag har även studerat drivkrafterna bakom implementeringen samt vilka företagsspecifika förutsättningar som kan påverka lösningen.Undersökningen har genomförts genom en fallstudie och tre företag har studerats. Den empiriska undersökningen har visat på en stor skillnad mellan företagens valda lösningar och även tydliggjort vilka faktorer som kan komma att spela roll vid utformningen av en BYOD-lösning. I analysen har sedan de olika lösningarna jämförts med varandra utifrån ett underlag som tagits fram ur litteraturen.

Denna studie av den digitala marknaden för svensk dagspress är ett examensarbete utfört åt kvällstidningen Expressen. Undersökningen syftar till att utreda den strukturella marknadssituationen för svensk dagspress och dess förutsättningar rörande framtida närvaro i surfplattan. Via intervjuer med branschexperter söks tolkningar om läsartrender och behov i surfplattan, paketeringsstrategi och behovet av personifierade nyhetsflöden. Undersökningen och dess tolkningar understöds av en inledande litteraturstudie vilken behandlar den svenska dagstidningsmarknaden, dess digitala transformation och tekniska förutsättningar gällande surfplattan och rapporterade konsumenttrender.Studien visar bl.a. att den svenska dagstidningsmarknaden är utsatt för en hög intern konkurrens vilket ställer höga omställningskrav på bolagen i en digital era.
