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.

The dialysis ward at Karolinska University Hospital is a highly pressurized work environment filled with critical treatment situations where patient?s lives can be constantly in danger. 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 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.

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.

Cochlear implant has become a common treatment for people with severe hearing loss. As the field of cochlear implants is developing rapidly a larger group of patients will be implanted. Therefore, it can be of interest to identify which complications are most frequently occurring. Objective: The aim of this study is to identify and present the most common complications in cochlear implant treatment and to identify surgical issues that have to be addressed during implantation. Method: A review of retrospective case studies regarding complications has been made.

People working with handling parcels in terminals are often victims of musculoskeletal injuries. This is largely due to the hazardous lifting of too many parcels which are too heavy and unsuitable work postures. The human body?s ability to lift and grasp objects is so outstanding that developing a device with the same capability is very difficult.The goal of the project has been to develop a technical device that will improve the handling of parcels with regard to ergonomics. The area of concern was the lifting of parcels between the conveyor belt and the cargo space of the freight car.

The use of mobile devices has increased dramatically in recent years and the development of newtechnologies has made it difficult for developers to know what screen size and device the visitor isusing. This has resulted in the fact that today there is a problem with the interface for web pages onmobile devices. They are not adapted to the flexibility required for the interfaces to be recognizedon various mobile devices. Instead of developing two separate web pages, where one is designed formobile devices and one for desktop and keep them both continously updated, responsive webdesign simplifies the work process. Responsive web design is a flexible and dynamic interface thatadapts to mobile device and screen sizes.

The parallel bars is used in physical therapy and is mainly used for patients who have to train walking and balance after a stroke or an operation. It consists of two long handrails with two legs on each handrail. These legs go down into two ground-plates and are locked at the wanted height with a pin. The parallel bars is an appreciated device and is used on a daily basis in many care units.The main issue with the manual parallel bars is that it is very difficult and heavy for a single person to adjust the height of it. If a larger adjustment of the height has to be done, the legs have to be adjusted one at a time otherwise the they will be locked.

The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.
