This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.

This paper evaluates the prospects for utilizing aquaculture effluents as a nutrient source in organic hydroponic, as is the case in aquaponics. The development of organic hydroponics is dependent on replacing synthetic fertilizers with organically derived nutrients, such as those found in aquaculture effluents. Also, in hydroponic cultivation the establishment of a plant pathogen suppressive micro flora is part of the plant protection strategy. Therefore, both nutritional and microbial qualities of aquaculture water and organic hydroponic nutri-ent solution were analyzed and compared. Results showed both aquaculture water and or-ganic hydroponic solution to be deficient in a number of essential elements, although or-ganic hydroponic solution was closer to recommendations.

We performed our thesis at SCA Hygiene Products in Falkenberg. Our task has been to present a suggestion for a solution of the packing of giveaways that the company uses.In the current situation the work is performed manually, and the company wants to automate the process.

The product choices we have made are based on existing solutions.To help, we have used Fredy Olsson's books in principle and primary structure.

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.

Thereafter, an evaluation of the two prototypes are madethrough user testing. Finally, the results of the evaluation is presented and are relatedto the concepts of usability and likeability. .

The public service within health and care has changed remarkably during the last 30 years. It has been inspired by management ideas from profit-making businesses. Those thoughts are an umbrella term called Nex public management. In what way has New public management influenced the public service in Sweden? Important concepts in the change of public service are quality, effektivity and goals.

The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

Jönköping Energi AB (JEAB) is a local energy supplier for the county of Jönköping. JEAB also maintain the local Metropolitan Area Network (MAN). They have recently installed GPON in a portion of their network and have connected it to the MAN via an Extreme switch.However JEAB would prefer to use Cisco equipment instead of Extreme since the MAN comprises of Cisco hardware. They require a solution to connect GPON to the MAN with a recently purchased line card (Cisco 7600 ES20) which can be installed in a Cisco 6500 Catalyst switch. There is also a possible solution with an Alcatel-Lucent 7450 ESS-1 switch.

The graduation essay has been carried out in co-operation with Kalmar Industries in Lidhult, Sweden. The purpose of our essay was to develop a complete construction solution on a hoist that could lift a laying wheel, lift it up and then turn it 90 degrees. After that the wheel shall be placed in a special holder.The background of the essay is a record of reports of damage wheels when they been incorrect lifted with a forklift. The hoist shall be used together with the same forklifts that manage the wheels today. Together with our instructor at Kalmar Industries we developed a requirement specification and from that we got free hands.However this was not the main task from the beginning, then a simular hoist should be develop but used directly in the assembly workshop without using a forklift.We started to find principle solutions that later was evaluated against the requirement specification.

One of today problem at IVT industries would be assembly of insulation on water cisterns. The element of assembly insulation on the cistern gets too elevated; hence one has to climb onto the stand the cistern is assembly on. This will increase the risk of work related injuries when there is a risk of falling down. It?s also rather strenuous on shoulders due to work with your arms high above your head.

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

The primary purpose of this thesis is to study how political agents construct and give meaning to the concepts of democracy, representative democracy and referendums. The starting point of the thesis is the pressing issue whether or not Sweden should hold a referendum on the new EU constitution. To analyze this question my choice of method is critical discourse analysis and the topical theories revolve around democracy and responsibility.My study shows that there are three different discourses in this debate: ?the democratic process?, ?the representative democracy? and ?the concept of democracy?. However, the meaning of the concepts in these discourses varies depending on which side the political agents are on.

This report investigates a possible solution to the problem with adapting wave powerplants to work in countries with tidal water. The wire connecting the buoy at the surface with the generator at the bottom needs to adjust to the varying water depth. Our solution to this problem is to attach the wire to a jack which is then placed inside the buoy. The jack is then powered by an electric engine. The report discuss what forces the buoy will be exposed to and then the structural integrity of the design is evaluated through simulations.

The aim of this study was to examine how the interviewed teachers in one school observe their view of gender and equality regarding the educational system.  Accordingly, I would like to present my intention with this study, also be to analyze how the interviewed teachers way of working with matters of gender and equality, carry out as a portrait of their values considering the distribution in terms of gender. The research questions are the following: What is the teachers view on the concepts of equality and gender in school?How do different teachers talk about their way of working in relation to gender and equality in school?How is boys and girls images presented in the teachers descriptions in their discussion about gender and equality?This study is based on a fundamental qualitative method, where a handful number of teacher?s from one school were interviewed in order to obtain information and data for the examination. The interviews were analyzed and discussed in association to earlier research in aspiration to study different writer?s theories about the conception of gender and equality.
