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 study aims to investigate student participation as a tool for democratic development in secondary school from a student perspective. Furthermore, students' perceptions of the school's work with student participation in formal and informal contexts are also investigated, with basis in the teaching structure. The results are based on interviews conducted with students who all attend the same class in their last year of high school. Subsequently, an analysis is made based mainly on three different theories: democracy, curricula and sociocultural theory. The result shows that students feel that they are able to practice student participation but the amount of influence they get differs between individuals depending on devotion and commitment.

This study, a document analysis with a qualitative approach, explores children, under 18years, who have been subject to measures of child welfare in the city of Malmö during theyears 1935-1937. It also explores the school's role in this context. The questions that the studyis guided by is: How was children described in the Child Welfare documents in Malmö duringthe years 1935-1937? And what role did the school have in Child Welfare work and whatmotivated this? The theoretical approaches are Foucaults theories of power, control anddisciplining.It appears from the study that the school and child welfare authorities had a close cooperationwith the purpose to control the upbringing and disciplining of the children. It was through theupbringing that the deviant child would become a "normal", docile and good, industriouscitizen.

In one of six garbage collectors area in Cairo, Esbet el Nakhl, there's a handicap school run by the Coptic church. We chose to study this school using observations and interviews. The purpose of our thesis has been to describe the school, the goals of the education and the educational forms. The questions we asked our selves before the trip to Cairo were; how does the school look like? What's a garbage collectors area? How do the teachers educate the children? How's the situation for the handicapped children?We spent six days of observations and interviews at the school gathering information for the thesis.

This study in political science examines the UN adopted resolution 1970 (2011) andresolution 1973 (2011) on the basis of foreign policy decision-making. The study aims toexplain how the UN principle of Responsibility to Protect came to be legitimized for the firsttime by the UN Security Council in the Libya conflict in 2011. By a poliheuristic perspectivethe study attempt to explain Russia and China?s acting in the voting of resolution 1970 andresolution 1973. The background to the conflict in Libya 2011 is presented in the study aswell as the Security Council?s actions during the conflict, from the beginning of the conflictuntil the adoption of resolution 1973.

The purpose of this study is to compare the conditions for teaching and learning Sami at primary level in three different types of schools. The study focuses on teachers' views on multilingualism and characteristics of good mother tongue education as well as factors inside and outside school affecting teaching. The classroom environment is also discussed. Six qualitative interviews with practicing teachers in the three school forms were carried out: Sami school, integrated teaching and mother-tongue education. The results showed that the teachers are in favour of multilingualism and feel a responsibility to help more children develop their ability to speak Sami.

This thesis highlights the importance of social relationships for high school adolescents? identity in a multicultural school in Stockholm?s suburb. The second purpose of this thesis is to shed light on, if the school sees the students? cultural background as an asset and how teachers can take advantage and implement it to the way they teach .The theories in the study were developed by Urie Bronnfenbrenner; The ecological theory, Pierre Bourdeau; The three forms of capital and George H. Mead; The significant other, The generalized other and "I" and "Me".

SummaryBackground: Management control is important for all kinds of activities, both in trade and industry and in the public sector since you must economize on scarce resources. There are nevertheless many different views on management control, which have changed with the times. With regard to the public sector in Sweden, the management control systems have changed radically the last half century, especially from the 1980s, due to depressions and increased focus on effectiveness. New approaches have been taken by many municipalities and county councils, both in Sweden and internationally, where the former management control systems have been abandoned in favour of result control, target costing, and activity-based-costing, for example. Another new approach has been the Balanced Scorecard, which was introduced by Kaplan & Norton in a pioneering article in 1992.The Balanced scorecard is a multidimensional tool, originally intended to be used in trade and industry, but with regard to its nature, it has been adopted even by many non-commercial organizations, especially in Sweden.

With this thesis I wanted to find out how a teacher-team in Stockholm reason about and whether they have specific expectations of male teachers in the early school years. Interviews with five teachers from pre-school to grade 3 and in after-school have shown that specific expectations of male teachers is something obvious. Are male teachers expected to enter into the role of male role models to contribute with masculinity and a male perspective? However, the informants are not able to define how a male role model is or should act. Men and women are often defined as two separate, and often as opposite, groups.

To this date there are 14 major armed conflicts, four of which are defined as war. Every day several people come to Sweden as asylum  seekers and refugees looking for a residence permit in Sweden. This paper is about the children who receive a residence permit in Sweden and attend Swedish schools. Many of these children have experienced trauma ? damage to the psyche after a traumatic experience.From two qualitative interviews of a principal and a counselor at a school in Järfälla municipality, and three teachers at the same school, I studied what trauma management at this school looks like.

Abstract Many researchers in social work believe that in today's society require the interaction between organisations takes place on social problems. This study examined the interaction between the police, social services and schools.The purpose of this study are as follows; the aim is to investigate the interaction between social services, the police and schools about young people aged 12-18 years who are at risk for abuse and crime.My questions are: How do the different professions interact regarding young people at risk for abuse and crime? How do they meet young people in their daily work? What obstacles can the different professions see in interaction? What effects do the different professions see in interaction?The study is a qualitative study conducted with semi-structured interviews. Respondents have been two from each organisation.The theory used in the analysis of empirical data is new-institutionalismen. New-institutionalism is a theory developed from organizational theories.

This report describes necessary steps for an implementation of an environmental managementsystem at a secondary school and what would hopefully lead to an environmentalcertification, using ISO14001 ? or as a possibility ? one of the so called environmentalawards. To the largest part, the descriptions and activities are general and can be used at anysecondary school at all, but the current status analysis ? with the started environmentalinvestigation ? and the environmental policy are directly coupled to Wilhelm HaglundsGymnasium. The document should work as a process support for implementation of anenvironmental management system at a secondary school..

Abstract This examination work is about the role of physical activity for students with concentration difficulties. The purpose of this work is to describe educators experiences of how students with concentration difficulties are affected by physical and motor activity during school-time in primary school. In the work I assume from my questions that are: How do educators experience students with concentrations difficulties? Do educators think physical and motor training during school-time matter for the students learning processes? How? Do students with concentration difficulties have other possibilities than other students regarding physical and motor activity during school-time? I am using a qualitative interview method for answering my questions. The interviews are conducted in collaboration with three educators in a medium-sized Swedish F-6 school.

A Geographic Information System (GIS) is about presentinginformation with the map as a base. This is increasingly being used on internetsites and in mobile apps. With a GPS it is possible to see where you are andhow to reach a destination or check if the bus is in time. A question to ask isif this technology is possible to implement in ordinary primary schooleducation. If it is, learning history, geography, religion and so on with a GISlearning tool might be possible.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.
