Finns det faktorer som särskiljer Stockholmsbörsens sanktionerade bolag från dess övriga bolag - En studie om Nasdaq OMX Stockholms Disciplinnämnd
Abstract: The purpose of this study is to examine whether companies listed at Nasdaq OMX Stockholm (Stockholmsbörsen) sanctioned by the legal unit Nasdaq OMX Disciplinary Committee (Disciplinnämnden), could be distinguished from the remaining companies that have not been sanctioned. As Stockholmsbörsen is the most influential unit when trading shares in Sweden, listed companies need to behave in legal aspects. Actions and decisions that affect investors do also influence the listed companies and their performance. Some companies might be tempted to manipulate financial statements and public information to retain stakeholders; other miss to report properly without being fraudulent. To control this, the legal unit Disciplinnämden is introduced.
Analys av monteringslinan för luftbehandlingsaggregat (EC)
The purpose of the work is to analyze and balance an assembly line at Fläkt Woods in Jönköping. The work is going to answer the questions about today?s throughput time, how much waste that occurs, number of staff at the assembly line, how the supply of material works and possible improvements that can be made at the work stations. The work is also going to give a proposal of improve-ments that can be made.The methods used to get the result include observations and measurements, con-versations with technicians and operators and also data from Fläkt Woods? data-base.Large variations in throughput time are measured during the measure period, from 3 hours up to 5 hours and 35 minutes.
Konceptstudie av drivmodul till bandskotare med hybriddrift
BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.
Effektiv Planering enligt Lean Production : En fallstudie på Sandvik Mining and Construction
Due to a constantly increasing competitive pressure it is of great importance to constantly strive for improvements in order to gain competitive advantages. Lean Production is a concept that has been introduced with the aim to minimize waste and increase profitability. The purpose of this report is therefore to investigate how to perform effective planning according to the principles of Lean Production, in companys with customer exclusive products, through a case study at Sandvik Mining and Construction (SMC), and to investigate how SMC kan improve their planning of drifting rods at the production unit in Sandviken.The study started by creating a theoretical framework, to describe the subject planning and planning based on Lean Production. This frame work constituted the base for the case study which took place at Sandvik Mining and Construction, and also for the model and planning tool that has been introduced.The result of the study is partly a general model with factors that contribute to a more effective planning. These factors has beed identifed as SMED, which focuses on reducing set up times and in the end to facilitate the planning.

The project of developing a new instrument to replace it was assignedtwo students at the development engineering program at Halmstad University. The projectalso included integration of the new platform for DM 202 to HemoCue AB:s remainingproducts.The project began by defining the different technical areas concerned.
Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala
There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..
Faktorer som orsakar stress bland sjuksköterskor : En litteraturstudie
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.
Informationsmaterial för nya hyresgäster
Jag har arbetat med att producera ett informationsmaterial för nya hyresgäster hos hyresvärden Ydewalls i Katrineholm. Jag har använt mina kunskaper inom informationsdesign, textdesign och grafisk form för att utforma materialet. Syftet med informationsmaterialet är att ge de nya hyresgästerna den information som de kan tänkas behöva under tiden de bor i lägenheten. Ydewalls vill genom att förbättra sitt material minska antalet onödiga förfrågningar från hyresgästerna. Jag har arbetat efter min huvudfråga: hur skapas ett informationsmaterial utifrån de principer som finns inom informationsdesign? För att få svar på min fråga använde jag mig av metoder som litteraturstudier, komparation, deskription, enkätundersökning samt utprovningar.

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..
Relationen mellan cyklister och fotgängare vid Södra Älvstranden, Göteborg En utvärdering av trafiken på cykelstråket Älvsborgsbron - Centrum
This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..
Integrering av Digitala Färdskrivare och Telematik för den nya Europeiska Standarden
This Master of Science thesis project handles issues around managing data from the digital tachographsystem. European legislation states that companies must download the data of the digital tachograph systemand store it for at least one year for control purposes. The system stores data on the vehicle unit located inthe driving compartment and on smart cards personal for each driver.Acquiring data from the previous analogue tachograph was done instantaneously since the data wasphysically printed to a circular paper chart when driving. To acquire data from the digital system one mustperform a download from the vehicle unit and later transfer it to some form of backup solution for longterm storage. Data must also be downloaded from the driver smart cards.Download of data from the vehicle unit is the most time consuming task and may take up to 30minutes pervehicle.

Methodology: We mainly used interviews to gather information.
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.
