Visualisering inom Operativt Inköp
Visualization plays a key role in the concept of Lean. Lean was developed in Japan as a business philosophy in order to lead to an activity, where only steps that contribute to customer value of the final product are being performed. By defining the customer value and establish visualized standards, it is possible to see when situations differ from the standard. Then it?s possible to lead the process back on track.
ABC-kalkylering i praktiken
This thesis is based on an assignment from a unit within an international group manufacturing industrial products. The purpose of the thesis is to analyze and suggest ways to improve the cost accounting system in use at the unit. The main source of empirical data has been interviews with employees. The theoretical framework is based on a comparison between traditional/standard costing and activity-based costing (ABC). The cost accounting system in use is described in detail and classified as a traditional/standard cost accounting system.
Dokumentation av en experimentell biogasanläggning
This thesis is focused on identifying and documenting all electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief technical description and information of the systems around the reactors. Furthermore there will be a brief description of LabVIEW - which is a graphical programming language- and which devices / elements are programmed. For further notification, I am not responsible for the programming of the devices in LabVIEW which I have only used as a tool in my work. The plant for production of biogas consists of four reactors of which the third reactor (Lakbädden) is connected to another reactor (UASB) where they cooperate with each other. The reactors are used for producing biogas in the form of methane gas.The reactors I and II are connected to, various electrical devices as, flow meters, temperature sensors, frequency converter and more.
Operation Rolling Thunder
This paper provides an explanation of the concepts John A. Warden III describes regarding the use of air power and if this theory can be found, within the confines of an unconventional war. The U.S. ability to air power is overwhelming, however the right kind of warfare can force this great power to abandon their military and political objectives by exhausting its resources over time as it becomes increasingly costly, both economically, politically and morally, to wage war. The research deals with operation Rolling Thunder and John A.

Stavelsen som enhet i läsinlärningen : Ett specialpedagogiskt perspektiv
The aimof this study is to contribute furthermore to understand the complexity of theprocess of learning to read and write in an inclusive environment. It focus on the syllableinstead of the phoneme as a unit in this process which is not the most common way ofdoing it. The report is based on a qualitative analysis of this task in pre-school and gradeone at a primary school in a small municipality.In the result, I have found, that the very structured working process and the diagnosticapproach helps the teachers to understand on what level pupils are at. The pupils whostart working this way in pre-school, feel safe knowing what is expecting from them andthey also learn from each other. All pupils in grade one have, before w 45 in autumnterm, very good letter knowledge and have learnt how to read words with two syllableswith a consonant-wovel-structure.
En organisation i förändring. En fallstudie om Lantbrukarnas Riksförbund och riksförbundsstämman.
AbstractThe Swedish agricultural organisation, LRF, stands in front of many changes and the work with the changes in the organisation has caused some conflicts at the top. Is it like Michels say that it's a few people at the top that rules? The case with LRF shows to be something different, since the president Caroline Trapp was re-elected. The election committee proposed a new president, but the assembly had another opinion and re-elected Caroline Trapp. This shows that the opinions at the top were not the same as among the members of the organisation and the election committee couldn?t rule over them.In this essay I try to understand what kind of organisation LRF is and what made this case special.
Integrationens paradoxer : En intervjustudie av integrationen i praktiken
The purpose of this study is to examine the relations of power within the discourse of integration and my focus will be on power relations and structural discrimination. The study origins from four qualitative interviews with employees from the County administrative board as well as from the Employment office.The theoretical framework is based upon Social Constructionism, Postcolonial Theories and with an intersectional perspective. The recent critical research from The Official Report on power, integration and structural discrimination (Utredningen om makt, integration och strukturell diskriminering) is used as well as Foucault's theory of biopower which is discussed within the analysis.The study indicates that although integration often is addressed as a reciprocal process, it is still assumed that They should be integrated by Us. The present government's one-sided focus on employment has proved difficult for the employees to put into practise and when the responsibility of obtaining employment is based upon the individual alone, she/he becomes responsible for her/his own integration..
Könskvotering i bolagsstyrelser : Ett instrument för att främja en jämställd arbetsmarknad?
The European Union has been working to promote equality between women and men for a long time. Despite this, Sweden still have a gender segregated labor market where men generally has the leading positions. According to European law the member states shall promote gender equality and to take all appropriate measures. Statutory gender quotas for company boards is one such measure that some of the European member states have implemented in national law. The Swedish law has no provisions governing gender quotas and therefore the purpose of this study is to explain how gender quotas for company boards relate to current law, both of European law and national legislation.
Energisystemanalys av ABB AB LV Motors
With a larger awareness of the climate changes and increasing electricity prices, energy efficiency measures in the industry have become more common. By rationalize the activity and by the same time decrease the emission of greenhouse gases the company can both save money and reduce negative environmental impact. For the Swedish industries the electricity price have traditional been relative low, which has resulted in a considerable larger usage than other European countries. By a deregulation of the European electricity market the electricity price will level off between the countries, which will cause a higher electricity price in Sweden than we are use to. To prevent that the Swedish industry don?t lose competitiveness against the other European countries, it will require energy efficiency activities in all different forms.ABB Sweden has decided to decrease their total energy usage with five percent in two years.

Massundanträngning i samband med pålning i lera
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
Ersättning av Ringhals 3 med ett biobränslekraftverk
This study deals with the technical and economic feasibility of replacing the nuclear power plant reactor Ringhals 3 with a biofuel power plant. A technical investigation has been executed to determine which of the systems and components that could be reused and which ones would need to be replaced. The investment costs of the reconstruction have also been estimated. The cost of the electricity production has been calculated as well as the emissions of the new biofuel power plant. Based on the established rate of return, the lowest average spot price of electricity that makes the investment profitable has been calculated.
Att hantera kunskapsuppdraget med eller utan goda förutsättningar? : Hur åtta lärare ser på bedömning i särskolan
Media has the power to influences society. Some call them the third power of a state. Through amongst others, the agenda setting theory and the framing theory, this report seeks to understand how media describes the swine influenza and how it uses its power to influence people to vaccinate. As this report will show, there is no doubt that media has had an impact on the Swedish population of which 60 per cent followed through with the vaccination. Media used an information discourse and attempted to present its articles in an impartial manner and used governmental authorities and experts to support its arguments.
BIM i produktionen vid väg- och anläggningsprojekt
This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.
