Flockning och förtjockning i High-Rate-förtjockare ? en jämförelse med konventionell förtjockarteknik och lamellsedimentering.
In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.
Utveckling av instyrningsfunktionen hos ett dockningsinterface
In this project the task has been to develop a product that will facilitate an operation for personnel working in a sterilization center. The operation is to steer the front of a loading trolley into the chamber of an autoclave, a so-called docking. The moment is complicated because the margins to deviate from ideal docking position and still succeed, is very small.The principal Getinge's desire was that the product could be retrofitted at the customers on their existing systems. One of the demands was that the product should fit two types of trolleys, one with a adjustable working height and one with a fixed working height. Getinge is supposed to purchase the system from a subcontractor who shall manufacture it and the requirement from Getinge is that the cost of purchase mustn't exceed SEK 500Initially principles, solving the problem was developed.
Att finna den positiva avvikelsen : En fallstudie av en väl fungerande arbetsplats
AbstractDuring recent years the climate in recruiting new personnel has hardened as a result of high levels of employment and increasing competition in labour market. In order to resolve this problem, organisations have to adapt new strategies to attract and meet the demands of potential employees who have the required competence to meet job requirements.The aim of this study has been to examine a well functioning work place in order to elucidate explicit examples of what employees consider positive, and what can be ascertained as positive deviations. Narratives emanating from the unit manager and personnel illustrate their views on the positive influences found in their working place. Another ambition is to increase awareness and understanding about the factors that promote satisfaction in the workplace and positive deviation; and to utilise this knowledge.Traditional research on organisations has frequently focused on problems. The theoretical point of departure of this study is based on Positive Organizational Scholarship, abbreviated as POS.

Mjukvaruplattform för riggstyrning
Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.
Ersättning vid tvångsförvärv av mark ? En typfallsstudie av ersättningen i två olika ersättningssystem
Each year approximately 2,000 new detailed development plans are accepted in Sweden. When an area is covered by a new detailed development plan, it is often necessary that land has to be acquired to adjust the property units to the new plan. The owner conditions of the property units can usually be adjusted through negotiations between the seller and the buyer. But in some situations, when no agreements can be reached, it is possible to use coercive measures to purchase the land. Compulsory purchases are only permitted when certain legal criteria?s are met.
Hokus Fokus - gestaltning och utformning av rum för barn i sjukhusmiljö
In this project I have worked with creating a new kind of room in a hospital enviroment for children. The main purpose of the project has been to form a secure and positive experience for the patient while visiting a specific room at the department of childrens physiologi, at Drottning Silvias Children- and youth hospital in Gothenburg.The project was based on questions like how it is possible to move the focus from the unsecure and scary, to something secure and positive, when the patient is going through an testing situation.The target gruop included a wide age span (0-16 years old), therefore I have worked with a theme, H2O, that works for diffrent ages. In the room, I have applicated the theme in different levels that is changeable depending on the age of the patient.During the project I have presented my ideas for the staff at the hospital. We have discussed their problems, what they wish in their working enviroment and how they experience the situation for the patients. I have also asked the patients how they experience the specific room today.The result of the project is a visual idea of how you can create a room, that you don?t exepect to find in a hospital..
Gemensam konstruktion av förståelse i samtal som involverar personer med demenssjukdom
Dementia may cause difficulties in communicating. People suffering from dementia are therefore often described as being unable to take part in meaningful conversation. The responsibility to create understanding in a conversation is shared by all participants. By means of different strategies, participants in conversation can construct understanding through collaboration. How these strategies are utilized in conversation where one or more of the participants suffer from dementia is relatively unknown.
Konstruktion av en autonom vindstation
Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.
Automatisk nivåreglering av strålkastare
To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..
Utveckling av en webbaserad donationstjänst för företag som involverar medarbetarna i processen
In recent years, employees at large companies have started to demand that their employer should work more for good causes. The money the company wants to donate to charity is distributed mostly through a vote to decide where the money will be remitted. The purpose of this design case is to develop a design concept for a web-based donation service that involves all employees at a company. Furthermore, the authors of this study intends to explore how the motivation for employees of a company can be affected by participation in this service. In this design case, the service function, quality and concept was tested and evaluated.
Hörde du inte vad jag tänkte? : En kvalitativ studie om medarbetares förväntningar på enhetschefers ledarskap och konsekvenserna om förväntningarna inte uppfylls
The aim of the study was to gain a deeper understanding of the expectations that assistant nurses in the elderly care have on unit manager's leadership and the consequences if the expectations are not met. To answer the purpose of this paper a qualitative research was conducted with interviews with six assistant nurses in municipal elderly care. To analyze the empirical material communication were used as a theoretical concept. Communication includes codes, signals and messages to be interpreted by the parties in a conversation and they can be both verbal and nonverbal. This means that communication is complicated and can cause confusion if it is interpreted wrong.
Konstruktion av fackla för biogas
Värmekollektor in Sunne is a company whose main occupation is to collect the gas produced inlandfills. The gas contains about 50 % of Methane which is a greenhouse gas 20 times worse than CO2and should therefore not be allowed to leak into the atmosphere. The Methane is in as large amount aspossible used in different plants for example heating of households. But there are occasions when aflare is needed to burn the excess gas at standstills or testing of new landfills. The Flare only burns themethane to reduce the hazarder?s effect of the environment, it does not take advantage of the energy inthe gasThe goal of this master thesis was for me to create a foundation for an in-house production offlares for Värmekollektor.

Webbsystem för matprisjämförelser
This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
