Automatiserad mätning av kvalité : Varför är inte all mätningautomatiserad?
AbstractThis bachelor?s thesis at the Department of Production Engineering at the Royal Institute of Technology in Stockholm deals with the subject of automated metrology. The degree of automation of tasks within production has been a growing trend but the measurement of quality has not followed the same trend. The main thesis follows:What incentives are there to automate the measurement of quality in production?What factors are crucial and why are not all metrology automated?The thesis comes along with a number of sub-queries and delimitations.The working method includes both theoretical and empirical studies.
Bibliotekariens nya arbetsmarknad
The purpose of this thesis is to examine why graduates in librarian- and information science are employed by private companies. An initial explanation could be the influence of information technology and its impact on the librarian. A second factor relates to how employers regard the librarian outside the confines of the traditional labour market. The study is primarily based upon qualitative interviews with representatives of Swedish companies who have employed librarians since 1993, the year that the education achieved third level academic recognition. Theoretically we relied upon Manuel Castells discussion on the rise of the information society and its influence on companies and the labour market.

Unified Flow Sensor
Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.
Utökade tillämpningsmöjligheter för turbinlösning i våtpartiet hos tissuemaskiner : Konceptförslag som möjliggör tillämpning av turbinlösning för maskiner vars banbredd är bredare än 2,9 meter
AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.

Their audience, as for all online newspaper?s audience, has big expectations of a steady flow of news. The economic conditions of journalism, together with the interests from the owners, may force newspapers to produce large quantities of news for cheap costs.
En studie i hur järnvägens möjligheter kan appliceras inom AB Volvo : med hänsyn tagen till företagets logistikkrav
In the year of 2011, the new CEO of AB Volvo announced a major reorganization. This reorganization was a contributing factor to the start-up of this thesis.Volvo Group Logistics Services (VGLS) is Volvo Group?s global logistics partner, which designs, manages and optimizes all of the group's incoming and outgoing logistics flows. With the reorganization, VGLS started a project regarding responsibilities around railway flows. Within the project a demand to collect logistics requirements occurred.
Unesco, Malraux och ombildningens museum : Estetik och kosmopolitik i efterkrigstid
An inquiry into the post-war European aesthetic and political landscape should take the international organization Unesco?s colour reproductions and travelling exhibitions of paintings into consideration. In these, the organization implements André Malraux? idea of the ?imaginary museum? as a framework for a future cosmopolitical, aesthetic (and utopian) community. During the late 1940?s, the Swedish government also discusses the need for raising an ?aesthetic awareness? amongst their citizens as a consequence to a poor knowledge in the fine arts.
?Killar skriver inte puttinuttigt? : En experimentell studie av genusföreställningar i textbedömningar
This thesis examines conceptions of gender revealed by people when assessing texts. The research questions are: What associations can be discerned between gender conceptions and ideas about the quality of texts? What features of content and style are perceived as female or male? The study seeks to develop a method for comparing different people?s assessments of the same text. The material was collected by means of questionnaires in which 114 informants were asked to assess three anonymous student texts and then guess the sex of the writer. The material has been analysed quantitatively by correlating the assessments of the texts with the guesses about the sex of the author, and qualitatively, as the informants? freely worded assessments of the texts were analysed for content and form with the support of assumptions about how assessments are expressed in text.
Fosforavskiljning i reaktiva filter vid småskalig avloppsrening
An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.
Restriktioner av växthusgasemissioner : hur påverkas lantbruksföretagens ekonomi och produktionsinriktning?
The agricultural sector accounts for about 13 percent of the total load of greenhouse gas emissions from Sweden (Swedish Environmental Protection Agency, 2007). The Swedish objective to reduce the greenhouse gas emissions with 40 percentage units to the year of 2020, based upon the year of 1990, might imply stricter regulations for Swedish farmers. A regulation or other forms of economic incentives is probably necessary to reduce the emissions originating from the agricultural sector.
This study aims to investigate the economic and managerial impact on two agricultural firms with differing production system given that a constraint on green house gas emissions is introduced. Gases included in this study are carbon dioxide, methane and nitrous oxide.
Kvalitetsförbättringar och Emballageinstruktioner
This report is the result of a thesis carried out at the Department of Innovation, Design and Technology (IDT), at Mälardalen University on behalf of ABB AB Machines.The year was 1988 when ASEA and Brown Boveri formed a joint venture under the name ABB (Asea Brown Boveri).We perform our thesis at the division Discrete Automation and Motion where they primarily develops, manufactures and sells synchronous and asynchronous AC motors and generators.The main purpose of this thesis was initially to write a general packaging instruction, but the priority changed to develop more specific packaging instructions for Rotors, Stator gables, Bearing support and Outer Cover (plates) instead.The work started off to deal with a problem about that the staff had to start its work to grind away rust on the stator gables due to those stored outdoors. The result was mainly an investment in a new gable rack so that the material can be stored inside, as well as a packing instruction as it was originally intended.The problem on the bearing supports were that the staff thought it was demanding and difficult to clean them from the rustproofing they were greased in. If it is not possible to remove all rust protection it can cause the paint to not attach properly. After having compared with similar articles a test were done to order a pair of bearing supports without corrosion inhibitor, which gave good results. This initiative also set in motion a process to do the same for more different items.For special pallet, a survey were made of the process with two different VSM and a calculation of how much ABB would earn at ordering more special pallets than getting the material delivered on the A-pallets.
Gasbedövning av gris inför slakt : koldioxid eller alternativa gasmixturer?
I Sverige är det lagstadgat att djur skall vara bedövade innan de slaktas. Att upprätthålla en god djurvälfärd i slaktsituationen är inte enbart en grundpelare i vår svenska djurskyddslag, utan även en ständigt aktuell fråga som engagerar både livsmedelsproducenter likväl som konsumenter. Bedövning av grisar utförs i stor utsträckning med hjälp av koldioxid. Denna metod är vida omdiskuterad och ofta ifrågasatt ur djurvälfärdsaspekt. Detta då gasen är erkänt aversiv för djurslaget ifråga.
Direct-EGR tillämpat på HCCI
The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.
Optimerad styrning av kondensatorbatterier - Ny möjlighet att minska förluster med elektronisk brytteknik
Transmission of reactive power is well known to cause active power losses. Thus, newcomponents who can help minimizing these expensive reactive power flows are ofgreat interest to the power distribution companies. ABB Corporate Research hasdeveloped the first electronic power breaker. One possible application for thisbreaker is transient-free switching of capacitor banks. This could prove a usefuldistribution voltage complement to the switch-sync technique, mainly applied to transmissionvoltage level.
