SJ:s hantering av fordonsfel- analys ur ett helhetsperspektiv

The project description is to draw an extension or annex to the existing Nationalmuseum building from 1866.The annex is designed to complement Nationalmusems activities and contain internal and public functions. Artentering the building must not be crossed by public visitors. Art and staff must be able to seamlessly move betweenthe extension and the main building. The new building includes a public study room for scholars working withthe collection of art on paper, workshops, conservation studios, art spaces and warehouses. Additionally, theannex is designed to host a large number of office spaces.With the renovation of Nationalmuseum they intend to open up the today built in south atrium.

Nanostrukturell ytbeläggning på utsatta delar av marina drivlinor

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Ljussättning av det lilla trädgårdsrummet :

Sammanfattning Eftsom kalla Sverige blir mörkt ganska tidigt på kvällen på höst, vinter och vår ville jag se hur man kunde förlänga användandet av det lilla trädgårdsrummet både i tid på dygnet och i tid på säsongen. Jag tycker att ljussättning är en viktig del av gestaltningen, belysningen gör trädgården levande. Mitt syfte med arbetet var att skaffa mig grundläggande kunskap om ljussättning och ljuskällor, för att sedan skissa på koncept för det lilla trädgårdsrummet. För att lyckas med detta behövde jag ta reda vad ljus är och hur det fungerar. Ljuset har många olika egenskaper, t ex olika våglängder, och färger.

Undersökning av sambandet mellan strålningstemperatur och NDVI i Sahel

Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.

Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp

At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.

Beteenderesponser hos farmuppfödda minkar (Mustela vison) hållna i stora och berikade burar :

The standard housing of farmed mink provides little opportunities for them to behave naturally and abnormal behaviours such as stereotypic behaviour and tail biting may occur. To prevent abnormal behaviours animals in captivity are often provided with different kinds of enrichments. The aim of this study was to investigate what kind of enrichment farmed mink use when they have several kinds to choose from and to observe if abnormal behaviours can be decreased with a larger cage and a more multifaceted environment. Totally 20 silver blue, 10 months old female mink were kept in traditional cages (80x30x40 cm) for 7 days and in larger cages (195x80x40 cm) with several types of enrichments for 7 days. The enrichments were wire net- and wooden shelves, wire net- and plastic cylinders, water bath, plastic ropes, branches, straw and tennis balls. One-zero scan sampling on behaviour and choice of place were performed during 3 hours and 20 minutes prior to feeding during 7 days per treatment in April 2004.

Konsultchefers upplevelser i yrkesrollen : En kvalitativ studie om konsultchefers rollhantering, känsloarbete och ledarskap på bemanningsföretag.

Vi har undersökt konsultchefer på ett bemanningsföretag. Syftet med studien har varit att ta reda på hur de upplever sina olika roller, vilket känsloarbete de utför i dessa roller, samt hur ledarskapet ser ut i chefsrollen. Vi har utgått från ett individperspektiv och med kvalitativ ansats intervjuat sex konsultchefer på ett bemanningsföretag, för att ta reda på vår frågeställning: Hur upplever konsultcheferna sina olika roller (som chef och säljare) och vilket känsloarbete utför de i rollerna mot konsulter och kunder? Denna har vi besvarat med hjälp av tre huvudsakliga teoretiska ramar: Goffmans (2009) dramaturgiska teori, Hochschilds (2003)teorier om emotionellt arbete och slutligen Sandahl et al.s (2010) teorier om chefens roll i organisationen. Undersökningen visade att konsultcheferna upplever det vara viktigare att ?hålla rollen? som säljare mot kunder, än rollen som chef mot konsulter.

Beckholmen : Varv & Marina

A new shipyard on the island of Beckholmen consisting of a new ship hall and complementary workshops. The program is extended with rentable industrial space for other smaller companies to take advantage of synergies with the yard and to create an active maritime cluster around Beckholmen. By building a marina and a port at the northern shoreline of the island the shipyard can expand their potential customers to non-commercial and larger recreational boats that are becoming increasingly common in Skärgården. The port is also supplemented with a combined naval fuel station, harbor office and a small café. The boat traffic in the region gets a additional stop at the end of the port and act as an additional gateway to Djurgården. Several small retail spaces with direct access to the water is created along the promenade between the port and Djurgården. The shipyard gets a modern and efficient industry building, while the island is made available to the public again, and Beckholmen will hopefully take an equal place in the city's consciousness as it does visually in the inlet to Stockholm..

HUR KAN VI REDUCERA DEN INTERNA ÖVERGÖDNINGEN SAMT REGLERA ALGBLOMNINGAR FRÅN ATT NÅ EGENTLIGAÖSTERSJÖNS KUSTZON ?? : En vision om att återfå en balans i Östersjön genom att skörda algöverskott och använda biomassan som en framtida råvara.

The Baltic Sea is one of the world?s most polluted seas. Increased discharge of nutrients due to greater populations of people, together with a slow water exchange, creates great stress on the sea. Too much nutrients leads to increased growth of algae and causes problem in the ecosystem. Even if we reduce nutrient discharge the problem still exist in the ocean. When algae dies and sinks, more nutritional substances is produced called "internal eutrophication". This phenomenon will grow in the future due to a warmer climate and the problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production..

Tidssynkroniserade mätningar i vattenkraftstationer

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

Tredimensionell fastighetsindelning : med fokus på tillbehörsproblem

Real estate is defined as ground, which is divided into property. Ground means every part of the surface, which is situated within the country. There is no legal definition of property to be found. Property is usually explained as every unit, which legally should be registered in the register of landed properties. To constitute a property the property must permanently be suited for its purpose.

Produktionseffekter och behov av dikesrensning i Sveaskogs skogar :

Ökad efterfrågan på virke har lett till ett ökat intresse för och användande av olika produktionshöjande åtgärder. En sådan åtgärd är dikesrensning som innebär att befintliga diken eller dikessystem rensas för att de skall bibehålla eller återfå sin ursprungligt avvattnande och produktionshöjande funktion. Sveaskog avser att öka omfattningen av dikesrensning. Därför behövs en kartläggning av behovet på deras marker. På samma gång behöver produktionseffekterna och livslängden på dikena utrönas. Studien genomfördes via en studie av befintlig litteratur om skogsproduktionseffekter efter dikesrensning och dikning samt förfall och livslängd hos diken.

Modellering av indunstning på Södra Cell Mönsterås

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

Lagring av kyla i bergrum : Undersökning av ett nedlagt oljebergrum

This thesis considers the use of an oldrock cavern as thermal energy storage.With a large system of differentchillers a model was created to find anappropriate future system. There aremainly two trajectories to take. Eitheran installation of chillers needs to bemade or the rock cavern can be used tomeet the future demand of districtcooling in Solna, Sweden. Additionallythis thesis investigates the possibleuse of different techniques to utilizethe phase change energy of water.Simulation shows that it?s possible toutilize the phase-change energy of afluid; however it?s not economicallyfeasible due to the thermodynamiceffects on the Carnot cycle.

UNDER YTAN Fredrik Reinfeldt och Stefan Löfven i en komparativ bildstudie

Title: Under the surface - Fredrik Reinfeldt and Stefan Löfven in a comparative photo studyAuthors: Jon Demred, Fanny Wijk & Olivia WikströmLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishNumber of pages: 39This thesis compares how Stefan Löfven was being portrayed in Swedish media the week after the generalelection 2014 with how Fredrik Reinfeldt was portrayed in the first week after 2006?s general election.There has been made a lot of research on how politicians are portrayed in the media, but most of theresearch focus on text portrayal. This thesis focus on something different, it compares how the two ?winners? were portrayed in news photos.A semiotic approach was used to analyse news images in the newspapers Aftonbladet, Expressen, SvenskaDagbladet and Dagens Nyheter. It was important to not only look at the pictures, but also the outer context, i.e the headlines, had to be analysed to come to any conclusions.Fredrik Reinfeldt was portrayed more positive and more as a winner than Stefan Löfven was.
