Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

Preschool has a long tradition of using picture books, both as entertainment and as a resource for educational activities. In science there are two main application areas. The first one is science concepts and the second is to teach basic science process skills. These skills, observing, communicating, inferring, classifying, measuring and predicting reflects the methods used by scientists. Picture books potential to put science concepts and activities that promote the use of science process skills in a meaningful context, recommends using picture books for this purpose.

A new curriculum, entailing news for teachers as well as students, was implemented in 2011. Among other things History has been given a more prominent position in that every student will now study the subject. Can this decision lead to history being used more in the future?The aim of this thesis is to study the new curriculum, Gy11, as well the Lpf94 and Lgy70, based on Klas-Göran Karlsson´s typology where the use of history is divided into seven different categories. I will analyze the curricula, looking at what different uses of history that can be discerned as well as what changes have been made over time.

The usage time is an important part of the specification for products powered bybatteries. The usage time is affected by a number of different elements; technical,environmental and how the product is being used. The method to determine theusage time is intended to define how measurements and calculations are to berealized along with influencing factors to keep in mind. With support from thismethod the intention is to gain control on how well the established usage time canbe expected to cohere with the real value and what affects the value.The study is done specifically for hearing protectors with battery powered built inelectronically functions. The functions can be level dependent function forambient hearing, 2-way radio communication, Bluetooth or FM-radio.The first chapter of the report describes the literature study performed in theproject.

The purpose of my study was to examine a competence-development in care of older people in which some of the personnel have been ?spjutspetsar?. More specifically my aim was to investigate how the personnel managed to supervise others in the organization. My main research questions were: How do the care-managers and the care-workers persecute their functions as ?spjutspetsar?? What form has the internal meeting between the competence-development and the organization ideology taken? What possibilities and obstacles have the care-managers and care-workers been confronted? In my study my research method is based on eight qualitative interviews.

This essay will focus on the significance of gender in toys´ portrayed in children books for the age 3-5years. The aim for the essay, partly, is to highlight how gender stereotypes can come forth and affect children through the way toys are illustrated within children?s books. The essay will address books from two different time periods, the first period being the 40-50- 60's and the other being the 00´s. The questions to be addressed in this essay is; what type of toys? children play with in the books used in the analysis, and if a change can be detected between the different time periods in terms of gender awareness in what type of toys are presented in the books.The main method used in this essay is an iconological image analysis in which the first step is mapping, other methods used is analysis and interpretation.

The aim of the thesis was to identify whether, and if so how, aspects of sexual health (reproductive health and cohabitation) are compiled in the National Quality Register and identify reasons for this. A quantitative method has been applied to go through the registers annual reports. In the first part of the thesis, the registers annual reports was mapped with the help of a checklist designed through World Health Organizations (WHO) definition of sexual health. In the second part, a questionnaire was sent to those responsible for each register to find reasons to why and how sexual health is included in the National Quality Registers. The result shows that sexual health is not usually included in the register data, although the survey showed that most registers brought up aspects that could affect the current target group's sexual health.

This thesis focuses on the motives and incitements for voluntary work. The main question for this thesis is why people get involved in voluntary work. What are the motives and incitements for voluntary commitment and what do people gain from this kind of commitment? The thesis is based upon qualitative research methods at Frivilligcentralen in Norrköping. The theoretical perspectives are a community commitment, satisfaction of being part of a meaningful context, altruistic and self-interest and an increased pace of social changes.

During the years 2005-2007 several cases of abnormal bleeding were seen after surgery in Bengal cats on veterinary clinics and animal hospitals in Sweden. In this study we have examined if the observed bleedings are due to an inherited defect of the coagulation cascade. Ten Bengal cats were tested for activated partial thromboplastin time (P-APT-time) and one-stage protrombin time (P-PK), and nine of these cats were tested for fibrinogen quantity (P-fibrinogen). Four of the tested cats had shown signs of an abnormal bleeding after surgery, and five of the cats were genetically related to these cats. One cat had a small bleeding wound at the internal base of the right auricle.

The aim of this project was to quantify the total sleep time in modern dairy cows during24-hour periods and to investigate whether the total amount of sleep as well as timespent in different sleep stages varies between the dry period, early- and peak lactation.The distribution of sleep time between night and day was also examined. Furthermore,correlations between sleep and lying time, fluctuations in body temperature and heartbeat were included in the aim. Eight dairy cows of the Swedish Red breed were used inthis study, which was carried out between June and September 2010. In order toquantify sleep non-invasive electrophysiological recordings were performed.Simultaneously with collecting sleep data, body position and body temperature werealso recorded. No heart rate data was obtained due to difficulties of maintainingelectrodes for heart beat measurements attached to the skin.

The purpose of this thesis was to study the importance of virtual communities for independent record companies. It also aims to examine how these companies use virtual communities in their marketing activities and how to gain competitive advantages by working with virtual communities. A case study based on interviews was conducted with managers from two independent record companies, Music Is My Girlfriend Recordings and B&B Records. Our study has shown that virtual communities are important for independent record companies as tools for finding and addressing the right target market. Useful information about the members of these communities can easily be gathered with the use of the various search options that are available.

During the 20th century Sweden faced an increased proportion of workers registered as part-time unemployed, especially in the care sector. However, due to many valuable efforts, aimed at solving the problem of part time unemployment and political decisions, the number of people who are part-time unemployed has declined since the late 20th century. We have investigated part-time workers preferential right to extending their working hours. According to Section 25 a of the Employment Protection Act, part-time employees who have submitted an interest in increasing their working hours has a preferential right to increased working hours, with the assumptions that full-time employment with the employer will meet a labor need that the employee has sufficient qualifications for.Qualitative interviews have given us information about how Karlstad Community and a private care company deal with part-time unemployment and their workers preferential right to extending their working hours. We have found that people who work for Karlstad Community have an opportunity to choose their number of workings hours, thanks to a political decision made in Karlstad Community, aimed at solving the part time unemployment in the care sector.
