A wastewater treatment plant has the task to refine the wastewater from substances that should not be released into the environment. The decomposition process can, in a simple way, be described as follows: micro-organisms breathe oxygen and eat unwanted substances. The environment in which the micro-organism lives is known as sludge and the correct amount of oxygen available in the sludge is important for the decomposition to be effective. The oxygenation of the sludge alone stands for about 30% of the plant?s energy consumption.

Radio frequency identification (RFID) is a versatile wireless technology usedworldwide. The fields of applications are many and its popularity constantlygrows due to smaller in size, better and less expensive components. RFID isused to identify, track or share information about an object using radio waves.This master thesis describes the process of designing and implementing ahandheld UHF RFID reader. The goal was to, based on a UHF RFID-chipdesign a fully functional, small in size and power efficient device. Amicrocontroller provides the user interface and is also used to control theRFID-chip and a Bluetooth device.

Studien grundar sig i att studera inte endast controllern utan även CFO:n på grund av att CFO:n utgör en viktig del i arbetet med ekonomistyrning. Syftet med studien var att beskriva likheter och/ eller skillnader vid arbetsuppgifter mellan controllern och CFO:n samt deras syn på hur den motsatta rollen arbetar. Detta för att öka förståelsen för rollerna som controller och CFO. För att genomföra studien användes en kvalitativ metod som omfattade öppna individuella intervjuer med controller och CFO på Halmstads kommun, Heléns Rör AB och CFO/ controller på Krönleins bryggeri AB. Den teoretiska referensramen delades in i följande teman: Ekonomistyrning, controllerns och CFO:ns arbetsuppgifter, rollen som controller, CFO och CFO/ controller, ledningsgruppen och faktorer som påverkar och samarbete.

Background: The project controller is a function witch evolved due to the strong gaining ground of project operation. Why the area of the project controller is interesting to study is explained by the fact that increasing knowledge of this function is important in order to make project operation work well. The fact that opinions in this field disagree, further increases the interest of the field. In order to study the function of the project controller three companies have been singled out. They are IFS, Intentia and Saab Bofors Dynamics.

It has been demonstrated in this study how people working in frontline jobs in service organizations are exercising ?micro power?. The use of ?micro power? is defined as ?to in ones professional role, without objectively defensible reasons, impose sanctions on a customer?. The interviewees are explaining their use of ?micro power? with mood, working conditions, and customers? behavior.

Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ? mistaking them for plankton ? or via prey.

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

The purpose of this essay was to find out how leaders in micro service firms practice HRM and identify which HRM related problems they experience in their leadership. A case study consisting two cases was carried out. The study has shown that leaders in micro service firms use a highly personalised, informal management and involve their employees in the firm?s development. The findings were that leaders of micro service firms do not have any theoretical knowledge of HRM practises because of lack of education.

Syftet med den här uppsatsen är att få en bild över hur en controller arbetar i ett medelstort företag. Studien har genomförts med en fallstudie av två företag över en tre veckors period. Studien visar att controllers i medelstora företag har många olika arbetsuppgifter. Controllern tenderar att arbeta med redovisning och den framtida styrningen av företaget har en lägre prioritet. Hursomhelst har vi funnit att en controller i ett medelstort företag har fler arbetsuppgifter än vad litteraturen beskriver att en controller har.

The idea for the thesis ?Construction and implementation of a mobile prototype; The Lovebomb? originates from doctoral candidates Rebecca Hansson and Tobias Skog from PLAY Research Group at the Interactive Institute in Gothenburg. The object of the master thesis is to construct two working LoveBomb prototypes, one mother console belonging to the LoveBomb and blueprints for both. The LoveBomb (the picture to the right shows a possible design) is intended to encourage people to express themselves emotionally when situated amongst strangers in public spaces. Two buttons control the device, which contains a radio transceiver.

Bakgrund:Teknologins utveckling samt den ökade globaliseringen har gjort dagens controller till ett komplext yrke som berör många aspekter. Vi vill behandla ämnet utifrån personer som ska anställa en controller eftersom de är involverade i controller-rollen. Vi undrar hur dessa personer egentligen kan veta vad de söker hos en controller när det råder en så stor osäkerhet kring begreppet.Syfte:Syftet med vår uppsats är att undersöka vilka förväntningar som arbetsgivare har på en controller samt analysera dessa med stöd av tidigare forskning och litteratur. Uppsatsen fokuserar på dels vad controllern skall arbeta med och hur arbetsuppgifterna utvecklas och dels på personlighetsdrag och färdigheter. Vi vill få en ökad förståelse på hur arbetsgivare via sina förväntningar tolkar begreppet controller.Metod:En kvalitativ forskningsmetod med abduktiv ansats.

Introduction: 1 November 2010  came the amendment about the audit requirement into force. The amendment concerned only micro-enterprises. The most common form offinancing for micro-enterprises are bank loans, therefore the banks play a major role in the business and wellness of micro-enterprises.Purpose: Purpose of this paper is to examine if the credit assessment has been affected by the removal of the audit requirement for micro-enterprises.Method: This study will be conducted by a qualitative study in the form of interviews. Five interviews were conducted, with four respondents from the large banks and    one respondent from Almi Företagspartner.Conclusion: All respondents agreed that the audit is seen as a mark of quality, some lenders will continue to request it from the micro-enterprise while other lenders look at other factors such as ownership, relationship or business concept..

In order for companies to be competitive they perform different types of development projects.  Due to globalization a greater focus is added on costs, not least on costs in development projects. Project controllers are involved in development projects in order to review the financial aspects. The authors have examined the role that project controllers hold in respect of two Swedish manufacturers, Volvo CE and Scania CV. The investigation has revolved around three main issues where the authors conducted interviews with controllers that do not work in development projects and project controllers in development projects. The goal of the interviews was to gain a greater understanding of the role of project controllers, how this role will differ from those that do not work in development projects and the difficulties faced by project controllers.

This thesis aims to develop a control system for measuring electromagnetic compability (EMC). This has meant that a controller designed around an ATmega8 microcontroller has been manufactured and programmed. It has also meant the development of a comprehensive control software in the program MATLAB. The control system has been tested with satisfactory results and can now, monitor and control measurements of the EMC-type..
