Simulering av vindkraftverk och närliggande elnät vid Risholmen i Göteborg i SimPowerSystems

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

Tankprocesstyrning med MATLAB via USB

Ett vattentanksystem och tillhörande styrelektronik utvecklades på Rubico AB i Luleå under sommaren 2011. Detta andra ordningens reglersystem består kortfattat av två vattentankar med individuella nivågivare, en pump och en störflödeskran. I dagsläget används utrustningen vid laborationer på Luleå tekniska universitet i en grundkurs i reglerteknik. Avläsning av nivågivare och styrning av pump i det existerande systemet sker analogt via ett externt DAC-kort kopplat mellan reglersystem och persondator. Regleringen sker på datorn med hjälp av mjukvaran RegSim.

Utvärdering av den upplevda användbarheten hos CySeMoL och EAAT med hjälp av ramverk för ändamålet och ISO/IEC 25010:2011

This report describes a study aimed at uncovering flaws and finding potential improvements from when the modelling tool EAAT is used in conjunction with the modelling language CySeMoL. The study was performed by developing a framework and applying it on CySeMoL and EAAT in real life context networks.The framework was developed in order to increase the number of flaws uncovered as well as gather potential improvements to both EAAT and CySeMoL. The basis of the framework is a modified version of the Quality in use model from ISO/IEC 25010:2011 standard. Upon the characteristics and sub characteristics of this modified model different values for measuring usability where attached. The purpose of these values is to measure usability from the perspectives of both creating and interpreting models.

Modebloggarnas makt : Hur produktplacering i modebloggar påverkar försäljningen i volymmärkesbutiker

By exposing their products in blogs, companies have the opportunity to reach out to hundreds of thousands of consumers daily. Instead of using conventional Internet advertising such as banners and ads, some companies chose to make use of product placement in blogs. By choosing to expose their products in blogs, companies use a medium that blog readers are familiar with and can relate to, and can thereby solicit customers for their products and brands.We will examine whether product placements in fashion blogs are an effective way for businesses to market themselves and their products. We measure this efficiency, by keeping a record of the sales of ten product placed garment and accessories that we have selected from four of the largest blogs in Sweden. The stores we examine sales of product placed goods in are volume brand stores such as Zara and H&M etcetera.

Övervakning vid allmän anestesi och stående ingrepp på häst

The purpose of this literature study was to describe techniques for monitoring general anesthesia and standing chemical restraint in the horse. A number of various techniques and devices related to e.g. blood pressure measurement, blood gas analysis and pulse oximetry are defined, and finally their clinical relevance and reliability are discussed. The equine patient is generally far more exposed to anesthesia-related risks than other smaller species. Complications such as hypotension and hypercapnia are commonly seen during general anesthesia. Thus, close monitoring is essentially performed by the veterinary nurse, whom is responsible for monitoring the anesthetized patient.

Mot mer flexicurity?

Since the 2006 election, the debate surrounding the Swedish labour market policy has intensified. There has been a discussion about a need for change towards a more flexible labour market. An example of this is on the other side of the strait, in neighbouring Denmark. Their flexicurity model, ?the golden triangle?, is characterized by a flexible labour market, generous unemployment benefits and active labour market policies.

Evaluation of Different Extraction- and Analysis Methods for Calprotectin in Feces

Background Calprotectin is a protein expressed in the cytoplasm inside the neutrophile granulocytes. During inflammatory bowel disease (IBD), the neutrophile granulocytes are involved in a complex interaction at the inflammatory area where they die and release their content into the intestinal lumen. Therefore, calprotectin in stool is a suitable marker for diagnosis and measurement of the disease-activity in patients with IBD. The most commonly used method to detect calprotectin in stool is ELISA, but the process of manual preparation of stool samples is time-consuming.Aim The objective of the study was to evaluate an extraction method that could replace manual preparation of fecal samples and to compare different methods for measuring Calprotectin in stool using two ELISA-methods from two manufacturers and one rapidtest.Methods For extraction of calprotectin from stool samples we used sample collector tubes from Epitope Diagnostics and fecal preparation kits from Roche. Two different ELISA-kits for measuring calprotectin concentration in stool were compared.

Sa?kerhet och integritet i webbapplikationer : En orientering o?ver sa?ker utveckling

The use of Web applications is a growing area. While the possibilities and functionalities are increasing, so is the complexity of them, together with the threats against them because the complexity also opens up the application to vulnerabilities. It is therefore important for developers to know how a web application can be developed with security in mind.This study?s intention has been to create an introductory documentation of what kind of techniques that exists which can produce higher security, which methods there can be within the development process and what to think about when programming secure web applications. In this paper we have investigated how theoretical manuals in the IT security department handles that area, and interviewed two developers from two different companies to see how they use security in their web applications.The study has an exploratory technical perspective and does not explain how to practically use and interconnecting different security-enhancing technologies, but is more suppose to give a first glance at what is available and sow a seed for those interested to continue reading further about the subject.

Corporate Social Responsibility - A case study about how to improve a company?s CSR work

Background: Since the start of the twenty-first century it has become very important for companies to act in a responsible manner, in guides of CSR. The idea is that companies have more responsibilities than to achieve a higher profit for their shareholders. They should also care about the society and act in a responsible way.Problem discussion: Problems concerning CSR are that the internal part of the sustainability work has not encountered the same level as the external part of the sustainability work. Companies are today struggling with implementing CSR into their business strategies.Research questions:1. What does a company has to consider when working with CSR? 2. How can management control systems help the implementation of CSR into the organisation?Purpose: The purpose of this thesis is to examine what a company has to consider when working with CSR and how management control systems can help the implementation of CSR into the organisation.

Automatisk mätning och detektering av röjande signaler

This master thesis has been performed at Sectra Communications AB in Linköping where they manufacture electronic encryption devices. In cryptology it is essential that an eavesdropper cannot find the plain text. To assure that a system is safe, all devices are thoroughly examined so that they don?t emit any secret information, so called Compromising Emanations (CE). This is done by comparing the secret signal with measured signals on the screen of an oscilloscope, a process that is very time consuming and furthermore, the risk of missing compromising emanations is high.

The Relationship between Internationalization and Firm Performance

Title: The Relationship between Internationalization and Firm Performance Seminar date: 5 June, 2008 Course: Masters thesis in Business Administration, Programme for Managing People, Knowledge and Change, 15 University Credit Points (15 ECTS). Authors: Cheng Hsun Chiang and Márton Pap Advisor: Dan Kärreman Key words: Internationalization, Performance, Multinationality, Degree of Internationalization (DOI), Country of Origin Purpose: To illuminate various crucial aspects of internationalization by systematically contrasting the different models of the multinationality-performance relationship and searching for underlying reasons. Methodology: Meta-analysis on previous theoretical and empirical research. Our emphasis in this paper has been put on the qualitative aspects of the previous research unlike many other conventional meta-analyses that focus on the comparison of the empirical data. Theoretical perspectives: Five main models have been developed by earlier studies to describe the relationship between internationalization and performance: positive linear, no or ambiguous relation, inverted U-shaped, standard U-shaped and S-shaped curve.

Undersökning av förskolan Temmelburken certifierad enligt Miljöbyggnad : Termiskt klimat, energianvändning och höjning av certifieringsnivån

WSP building physics in Stockholm has certified the preschool Temmelburken in Bromma with the system of certification Miljöbyggnad. The rating of the building became BRONZE. In this thesis the preschool has been investigated with respect to the three areas: thermal climate, use of energy and improving of the level of certification. The thermal climate at the preschool has been investigated by a questionnaire survey and by measurements in order to do comparisons between the results from the two investigations as well as with the results of the simulations that WSP has done at the certification of the preschool. The differences between the results from the simulations and the questionnaire survey for winter as well as from the measurement performed with a comfort meter the 19th of March are concidered to be reasonably small since they give rise to the same rating according to Miljöbyggnad.   Operational data for the use of energy for the preschool have been obtained in order to do comparisons with simulations performed by WSP and Svenska Besiktningar AB. The comparison shows that the simulated values for the specific use of energy are lower than what the real specific use of energy would be for the preschool, since just the operational data for the heat energy is higher than the simulated values. At the investigation of the possibility of improving the level of certification it was found that the rating of the preschool can be raised from BRONZE to SILVER by improving the ratings of the ?thermal climate summer? and the ?daylight?.

Intuition i beslutsfattande : En studie om det intuitiva beslutsfattandet och dess påverkande faktorer vid Akademiska sjukhuset i Uppsala

Managers operating within the dynamic society of today are said to rely on intuition when effective and quick decisions are to be made. This skill or phenomenon has aroused an interest within the academic world of management whom has explored intuition, its relation to decision making and its influencing factors, especially in the private sector. Intuitive decision making is however not isolated solely to this sector but also involved in decision making associated to the public sector. Therefore, the aim of the thesis is to investigate whether managers at the hospital Akademiska in Uppsala involve intuition in decision making and to what extent the factors time, amount of information, individual experience and decision complexity influence the intuition.The theoretical framework includes academic research regarding how intuition and rationality affect decisions, the concept of intuition and factors influencing the intuitiveness of decision making. Furthermore the theoretical discussion explores intuition connected to leadership, negative aspects of intuitive decisions and a comparison between different factors that separates public and private sector in terms of decision making.

Kvalitetsbristkostnader under garantitiden

Construction companies in Sweden have for recent years seen an increase in the numbers ofwarranty complaints associated with the market of resident buildings and the cost for this hasbeen measured to over 1.2 billion SEK per year. Working with poor quality cost as a way ofcreating insight about defects within the company?s processes is a method developed and usedby the manufacturing industry for decades, but have not yet reached the construction industry.This study has been performed in collaboration with a Swedish construction company, wherethe author has been stationed at the aftersales division for residential buildings. Owing tocircumstances, this published report has been made anonymous regarding the company whowill further on be namedthe Company. The Company is aware that warranty claims producegreat costs and has requested a way of putting cost and cause to specific claims in order ofreceiving a more specific cost view and to make the reuse of knowledge more efficient.
