A small wind power plant connected to the grid has been modeled in Modelica/ Dymola and controlled using external controllers written in C++. The small wind power plant consists of three wind power units with a nominal power of 3kW and one grid connection interconnected with an internal DCgrid. All the controls needed for control and optimization for the operation of the individual parts in the pl
I denna uppsats studerar jag hur manlighet konstrueras inom en grupp arbetare, närmare bestämt typografer. Materialet som ligger till grund för analysen är dessa typografers berättelser rörande deras yrkesverksamma tid. Syftet är att med Laclau & Mouffes diskursteori studera vad som konstituerar manlighet och hur den konstrueras i typografernas texter. Manlighetsforskarna Mosse samt Ekenstam &
Det har länge diskuterats huruvida PRV:s officialprövning av relativa registreringshinder bör avskaffas på varumärkesområdet. Inför den nya varumärkeslagen som trädde i kraft i juli 2011 diskuterades frågan först av Varumärkeskommittén år 2001 och sedan på nytt år 2008 efter begäran från näringslivet. Officialprövningen bibehölls dock oförändrad med motiveringen att användarna ansåg att fördelarnaIt has been discussed for a long time whether the PRV’s examination of relative grounds for refusal regarding trademarks should be abolished or not. Before the new Trademarks Act came into force in July 2011, the question was first discussed by the Brand Committee in 2001 and then again in 2008 after requests from the industry. However, the official examination remained unaffected, on the grounds
Problem/Bakgrund: Varför har enskilda individer som fångas på bild av övervakningskameror på allmän plats inte rätt att få tillgång till bildmaterial som de själva förekommer i? Syfte: Uppsatsens syfte är att undersöka huruvida utlämnande av bildmaterial till enskilda individer som fångats på bild av övervakningskameror på allmän plats skulle fungera stärkande för den personliga integriteten hos
LYCCA is a detector system consisting of different types of detectors which can be used flexibly to meet the individual requirements of different experiments focused on studying exotic nuclei far off the line of stability. It was developed for the HISPEC/DESPEC programme which is part of the NUSTAR collaboration at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. T
This report incorporates a product styling development concept carried out on Scania a vehicle manufacturer known for its premium long haulage trucks, located in Södertälje, Sweden. The report consists of the development of the writers’ conception and implementation of the term “Driver Focus” on Scanias truck interior. The project is carried out using various different industrial design techniques
Tetra Pak is a large scale organization that provides its customers with a food packaging solution based on laminated carton board in various package formats. The packaging material is produced in more than 50 converting factories represented world wide. The production develops the material in roll form that are loadable in the filling machines. Each roll arrives to the filling site with a barcode
A rising problem within electronics today is that, since the frequencies have increased dramatically, it is now very difficult to measure signals. If a traditional probe is used, then the direct contact will destroy the signal. The general idea behind this master thesis project is to make use of the crosstalk between transmission lines to create non contact test points. This thesis aims to evaluat
Today, vehicles are equipped with advanced electronics and complex alarm systems but still vehicle and cargo theft is a huge problem around the world. After struggling with this issue for several decades, the government in Brazil finally had enough and voted that all new vehicles manufactured or imported to the country are required to be equipped with an electronic device enabling tracking and imm
Denna uppsats behandlar normer och värderingar kring kvinnlig och manlig ära utifrån rättsliggjorda ärekränkningsbrott i Stockholm mellan åren 1474 och 1481. En kvantitativ metod i kombination med en hermeneutisk metod har använts för att komma fram till om ärekränkningarna tycks ha varit ett manligt eller kvinnligt fenomen under perioden. Resultatet visar en överrepresentation av män både när det
Abstract: The human gastro intestinal tract (GIT) plays a significant role in the well-being and has a significant impact on human health. Probiotics are the live microbial food supplement which alters the microbial composition in gut and prebiotics are the substrates that enhance the growth of probiotics. Our interest was to examine the prebiotic utilization of this probiotics and to check the c
Abstract The significance of terrestrially derived iron (Fe) for marine ecosystems and its implications on other biogeochemical cycles is well recognised. It has been recently highlighted that the concentration of Fe in several Swedish rivers has increased strongly over the last 40 years. Four rivers draining into the Baltic Sea were used in the present study in order to assess the aggregation pr
In this thesis, a novel method for characterizing Permanent Magnet Synchronous Machines(PMSMs) based in the dynamic response of the analyzed motor is evaluated. The most significant motor characteristics -torque, flux and efficiency maps- are computed from the motor voltage, currents and rotor position data sampled during the experiment. This way of obtaining the characteristics of the motor is po
Effekter av träning i fastande tillstånd Den tydligaste effekten av uthållighetsträning är förbättrad kondition. Ordet kondition kan definieras som samspelet mellan lungor, hjärta, blod och muskler. Lungorna ska växla syrgas från inandningsluften och släppa ut koldioxid. Hjärtat ska pumpa blod till lungorna och ut i kroppen. Blodets uppgift är att syresätta musklerna vid fysisk ansträngning. Allt
ABSTRACT The objective of this project was to study if the adaptive background affects the spectral sensitivity of budgerigars (Melopsittacus undulatus) tested in bright light. Two budgerigars were trained, by associative learning with food rewards, in dual choice tests to discriminate monochromatic light stimuli of nine different wavelengths from an adaptive background with ultraviolet light (UV
This project is a study that has described what condition based maintenance is and has examined the possibilities with condition based maintenance on the new A26 submarine. It finishes with a detailed case study of how a condition based maintenance system could look like on the submarine’s diesel engines. Questions that have been answered are; what is condition based maintenance and how does it wo
Abstract Ketoprofen, naproxen, diclofenac, and ibuprofen are four widelyused anti-inflammatory drugsthat areproduced in several kilotons each year.They end up in natural water recipients which couldvary inpH from around 6.0 to 9.0. Bearing in mind that most of thesepharmaceuticals are weak acids and therefore dissociates in different degree depending on surroundingpH and the chemical’s pKa, we ca
Ett nytt protein som hjälper Haemophilus bakterien att fastna i luftvägarna På ytan av luftvägsbakterien Haemophilus influenzae, finns en rad proteiner. Genom att flytta dessa proteiner till en annan bakterie, Escherichia coli, har vi visat att de kan binda till ett protein som finns i våra luftvägar. Bindningen till luftvägarna är ett första steg i etableringen av en infektion som sedan gör oss
