AbstractIt is important to choose which spare parts to keep in stock. With the right spareparts in stock the costs for inventory and production loss will decrease. Cavalieri et al. (2008) highlights that the balance between inventory cost and production loss is underestimated.  It affects the company and must be considered before decision on purchase.The problem with spare engines is that they are all more or less critical for the production. That can be a reason for why no previous research targeting engines and classification of with engine should be kept in stock has been found.

In the palliative care there are many close encounters between the care-taker and the care-giver. To be touched is foundational to every human being and the care-giver shows his presence to the care-taker, when he touch the care-taker. Touch is an important tool for the care-giver in the care for the care-taker. It becomes a natural way of communicating. The aim of this literature study was to describe which factors that are important, for the care-taker in the palliative care, to receive touch in the purpose of feeling well-being.

Around 30,000 people in Sweden suffer stroke every year, out of which about 12,000 end up with language difficulties, aphasia. Behind every person with aphasia there are significant others whose lives are also affected. Studies of how aphasia affects the health of these people are few. The overall aim of the present study was to examine how significant others of people with aphasia perceive their life situation, and how their quality of life is affected by the illness of their partner. Spouses of people with aphasia were contacted through aphasia groups and the Swedish Aphasia Association.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

The purpose of doing this essay was to illustrate how people living with chronic disease, dependent on medical technology experience their life situation. The study includes people with either dialysis therapy, mechanical ventilator or chronic oxygen therapy. A meta-synthesis was used as a method where a systematically review of studies that are made in a given issue compiles. Findings of the studies resulted in a synthesis of three themes: Limitations in life as a consequence of life-long treatment, to take responsibility for your life provide self-esteem and safeness, and to be cared for in different contexts ?help or prohibit.

This thesis has been carried out in autumn 2009 at Uppsala University for Boliden Mineral AB. Physical modelling has been used to model a comminution circuit. The model has then been linked to a PLC.When a concentrator is about to become operational Boliden Mineral AB have been looking for a way to test the PLC. The purpose of this report has therefore been to develop models for the subprocess in a concentrator and link these models to the PLC. The subprocess was a comminution circuit in Aitik36.

The purpose of this master thesis is to describe the professional and literary life of Karl-Gunnar Wall, city librarian of Katrineholm between 1944 and 1975. Questions at issue are the reasons for Walls literary interests, Walls choice of occupation, crucial personal meetings, the context in which Wall acts, Walls fundamental principles as a librarian and as a critic, and the features comprising Walls life history. The method used is a merely qualitative one called "life history". It is founded on in-depth interviews with the persons involved and emanates from the individuals own story about his life. I have carried out three taped interviews; one with Wall himself, and two with his colleagues.

Background During the child?s first year of life there is a continuous contact with the Child Health Services (CHS) and the parents feel confident and involved. After the first year, the visits to the CHS is reduced at the same time as the everyday life changes for the family as the child starts going to day-care and the parents often go back to work.Aim To examine what it is like being a parent to children aged one to five and what kind of parenting support parents of children aged one to five are in need of.Method Semi-structured interviews were used to interview 25 parents in 21 telephone interviews and one focus group with 4 parents. The recruiting of parents was done on site at one open day-care and with the help of CHS nurses in Sweden. There were 10 men and 15 women.

Background: Living with stroke not only means coping with physical limitations, but a stroke also leads to other losses, which in various ways may change an individual?s life. A nurse can play a significant role in regards to consequences in the ordinary day of life for patients with stroke. Aim: The aim of this literature study was to describe patients? experiences living with stroke.

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.

The purpose of this paper is to increase knowledge and understanding of how an identity is constructed on the internet and if it is different from the everyday identity. To analyze this, I have studied the theories of how identity is constructed in everyday life and then applied this on the empirical data that I have collected. In this study, I have chosen to pursue a qualitative approach using semi-structured interviews to gather the empirical data. In the study, six informants participated and all of them has an active social life both on and off the internet. The results that I have found in this study shows that an identity online is constructed in a similar way as it does in real life, however, some limitations that exist in everyday life do not exist online.
