Tågtrafikledare i praktiken : Informationshantering och systemanvändning vid Gävle driftledningscentral
In Sweden whenever trains or maintenance workers want access to the railway system, their requests of usage and movements are being supervised, granted and handled by train dispatchers. The profession holds a key role in making the complex railway system work in terms of efficiency, safety and delivering on-time arrivals. This master thesis, delegated by the Swedish Transport Administration, has been carried out at the Division of Human Computer Interaction at Uppsala University and at the train traffic control center in Gävle. The aim has been to map what information the train dispatchers use in order to make safety-related decisions concerning their working goals. And further to describe and analyze how the train dispatchers, visavi their tools and systems in the work domain, gather necessary information.The result indicates a complex, diverse and spread out setting of different programs, procedures and tools that make satisfactory fulfilment of efficiency, safety and punctuality in relation to the time table hard.
Utveckling av en dynamisk Simuleringsmodell av en skotare
The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

Produktsäkerhet i livsmedelsindustrin : HACCP inom bageri och konditori
During the last years, producers and consumers have become increasingly aware of food safety. Foodborne illness and foodborne injury are in best case unpleasant but they can also be fatal. HACCP (Hazard Analysis Critical Control Point) is a preventative food safety system which is aimed to guarantee production of safe food free from pathogens, foreign materials and substances with potential to cause adverse health effect. In order to succeed in developing, installing, monitoring and verifying a HACCP system, there is a mix of hurdles for the company to overcome. While larger food companies meet a difficult challenge, small and medium size enterprises often feel that the hurdles are almost impossible to manage.
Clas Ohlson : Hur påverkas styrningen i ett företag i och med en börsintroduktion?

Fjärrstyrning av videokamera
On some occasions it may be inappropriate with a cameraman behind the camera. In somecases there is no cameraman available or it is a smaller event, like a family celebration, to befilmed. It can also be difficult for a cameraman to shoot from certain angles. One solution forthis kind of situations can be to remotely control the camera movements. There are thosekinds of solutions on the market today but they either address professional filmmakers or thefunctionality is limited, for example by the absence of wireless remote control.This project aims to develop a solution to the problem with absence of wireless remote controland also a solution with more flexibility and less complexity than today?s solutions.
ISO 14001 : En genomgång av SSAB EMEA Oxelösunds miljöledningssystem
Environmental issues is now taking a growing place in society and to ensure that companies meet public expectations and do their part in working towards a sustainable development, environmental management system is said to be an effective tool (Almgren & Brorson, 2009).This case study has examined a company's environmental management system in order to find strengths and weaknesses within the ISO 14001 system. The work was carried out using interviews, document reviews and analyzes in which the three main concepts control the report ; "daily work", "audit" and "environmental aspects".The results shows that the daily work looks different depending on where you are; in the production or at the office. The audit examined all documents related to the environmental management system and the study showed that the biggest strengths was the commitment and waste handling while areas such as environmental goals and management review needed improvement. As a result of the deficiencies identified, suggestions for improvements was proposed. The investigation of the routine of the environmental aspects showed an incomplete routine where the red wire from identification to evaluation was missing.

Vårdhygien på infektionsavdelningar för smådjur ? en intervjustudie
BACKGROUND: The isolation facility is an important ward in veterinary hospitals. This is where infectious patients are treated in order to reduce the risk for cross-contamination between the infectious patients and other patients and humans in the hospital. But it can only function in a safe manner as long as adequate precautions for infection control are adhered to. This has shown to be a problem in many isolation facilities in veterinary hospitals in Sweden.
AIM: The aim of this paper was to examine which factors that can affect the quality of the infection control in the isolation facility. The aim is also to stress the importance of adequate infection control practices.
METHOD: Two interviews were conducted with staff from two veterinary hospitals.

Riskkapitalbolags styrning av portföljbolag i USA, Europa och Kina - En komparativ fallstudie
This thesis studies private equity firms' implementation of management Control systems in their portfolio companies and whether the systems are affected by cross-national differences. A comparative case study examines five different private equity firms to derive if there are any differences between the private equity firms' management Control systems in the United States, Europe and China. The empirical observations are categorized according to the framework developed by Merchant (1985) and further developed by Merchant and Van der Stede (2003). Theory on the effect of multinationality on management Control systems, also developed by Merchant and Van der Stede (2003), are used to explain possible findings. The applied theory includes the cultural dimensions developed by Hofstede (1984) and Hofstede and Bond (1988).
Balanserade styrkort i statliga organisationer - Om, hur och betydelse?
AbstractBachelor thesis G3 in Business Administration, Linnaeus University School of Businessand Economics, Financial Control, 2FE90E, Spring Semester 2010Authors: Kennerth Eriksson and Leo H KochAdvisor: Lars-Göran AidemarkTitle: Balanced Scorecard in governmental organizations ? About, how and its meaning.Background: The Balanced Scorecard is a Control system that includes both financial andnon-financial measures which intend to link the short-term business management with the long term vision and strategy. Businesses in the public sectors are different fromthe private sector on several levels and they often seek to reach multiple targets.Therefore, their choice of Control system becomes interesting. According to the SwedishNational Financial Management Authority (Ekonomistyrningsverket) among others, thereis no clear knowledge of how widespread the Balanced Scorecard is in governmentalorganizations. The lack of that knowledge is one of the questions at issue with this thesis.Is it only a few organizations that are using the Balanced Scorecard or parts of the model?Another question at issue is about how the Balanced Scorecard is used in the point ofcontrolling in the organizations we chose to investigate further.Purpose: The purpose of this thesis is partly to investigate the existence and use of theBalanced Scorecard in governmental organizations and partly to describe the design ofthe Balanced Scorecard in the studied organizations and explain why they have chosen towork with the Balanced Scorecard and what impact it has on them.Demarcation: The first part of this study has been demarked to only look at the existenceof the Balanced Scorecard in governmental organizations.
