Apputveckling : En studie av motsättningar mellan design- och användningspraktiker ur ett verksamhetsteoretiskt perspektiv
We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.
Think global, act local!? : Hur ett svenskt företag går till väga för att skapa ett enhetligt budskap i olika kulturer
An uncountable number of companies are present in foreign markets as a result of what we commonly choose to call globalization. This is especially true for Swedish companies traditionally operating on small markets. A company that is about to establish on a new market is faced not only with possibilities but also with challenges and risks. Researchers have found that companies that establish on foreign markets will have to deal with competitors on the national as well as on the global market, and therefore need consider how they globalize their brands. In addition to this, a brand can only reach international success if its message is coherent within and across every single market.
Clinical and subclinical mastitis in dairy cattle in Kampala, Uganda
Dairy farming in Uganda provides a source of food, employment and income. Previous studies have revealed high frequencies of bovine mastitis, a costly disease for the dairy farmer. The aims of this study were to investigate the bacteriological panorama in milk from udder quarters with clinical (CM) and subclinical mastitis (SCM) and to determine the antimicrobial susceptibility in staphylococcal isolates. Further, we intended to establish the prevalence of subclinical mastitis and to investigate some environmental factors and animal properties that might influence the frequency of mastitis. For CM, farmers made contact with the members of this study when recognizing an animal with CM.
Mätning av partikelmassa i avgaser från en dieselmotor
This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

Syftet med denna studie var att beskriva operationssjuksköterskors erfarenheter vid organdonation när donatorn är hjärndöd. Studien har en kvalitativ ansats, där forskarna strävar efter en helhetsförståelse av det studerade intresseområdet. Datainsamling utfördes via ostrukturerade intervjuer med öppna frågor. Sju intervjuer genomfördes med operationssjuksköterskor som medverkat vid organdonation när donatorn var hjärndöd.
Utredning av solenergi för drivning av sorptiv kylprocess för inomhusluften på Stockholmsarenan
Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.
Förstudie för en vindkraftpark på Malmölandet i Norrköping : En undersökning av förutsättningarna för en vindkraftpark på ett sen tidigare planerat område
This is a feasibility study that examines various aspects of building a wind farm on Malmön in Norrköping. The feasibility study deals with interests of conflict, park design, electrical connections, production calculation, financial calculations and operating- and timetable.The report is divided into two distinct parts. First a theoretical part, which deals with conflicting interests, park design and electrical connections. Second a part with simulations dealing with production calculations, and financial calculations.Opposing interests are mapped so that problem areas can be found, and help put focus on the right places at a future environmental impact assessment (EIA). There are a number of areas where planners have to assess on an EIA, this thesis point on the most important areas.
Product Return Process - Developing a Web-Based Return Form to Improve the Information Flow between an Apparel Company and Its Retailers
Handling product returns has become a critical activity for organizations as the volume of gods flowing back through the supply chain rapidly increases. Few research studies have published specific empirical data concerning the reverse logistics practices of companies. Information technology and information support has long been recognized as a competitive weapon ? capable of enhancing company performance and achieving efficient reverse logistics. Reverse logistics is very unlike the forward, as it is more reactive and also has less visibility.
Passivhus - lönsamt eller ej? : En jämförelse mellan ett passivhus och ett konventionellt hus
As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to conventional houses.
Kommunikatören inte bara ?nice to have? utan ?need to have? : En jämförande studie av kommunikatörens upplevda yrkesstatus i privat respektive offentlig sektor
Vårt samhälle idag präglas av ett ökat flöde av varor, tjänster och information och avståndet till världen runt omkring oss krymper. För organisationer innebär detta att kravet på effektivitet har blivit ett faktum och i samband med information kan begreppet strategisk kommunikation vara nyckeln till framgång. Vi som studerar medie- och kommunikationsvetenskap funderar ofta på vilka krav och förväntningar kommande arbetsgivare har på oss kommunikatörer som snart ska ut på arbetsmarknaden. Vi har också funderat på vilka arbetsgivare som bäst kommer att kunna möta vår strävan efter intressanta och utvecklande arbetsuppgifter. I den diskussion som just nu pågår har vi uppmärksammat att många ser organisationer inom den privata sektorn som mer attraktiva än organisationer inom den offentliga.
Skogsvård hos privata skogsägare : vilka åtgärder utförs och av vem?
Many participants in the Swedish timber market procure raw material from private forest owners. They often also offer forest services to ensure reforestation after final felling. Selling silviculture services can be a part of creating a long term relationship with the landowner for future timber purchases. The Swedish Forest Agency monitors forest rejuvenation results in the entire country. In the latest survey (2006 - 2008) the proportion of approved regeneration area was 78%.
Identifiering av merva?rden i EPC-projekt
In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.
Valutariskhantering vid rörelseexponering : En kvantitativ studie av svenska börsföretag
SAMMANFATTNINGTitel: Valutariskhantering vid rörelseexponering - En kvantitativ studie av svenska börsföretagNivå: C -uppsats i ämnet företagsekonomi.Författare: Gustaf Bergquist och Jimmy Mattsson.Handledare: Peter Lindberg.Datum: 2015 - juni.Syfte: Syftet med studien är att studera förekomsten av skillnader och likheter mellan svenska börsnoterade företags hantering av rörelseexponering mot valutarisk beroende på vilket segment de tillhör på Stockholmsbörsen.Metod: Studien är av kvantitativ natur med en deduktiv ansats. Data har samlats in genom internetbaserade enkäter som sedan har ställts mot tidigare forskning och teorier. Utfallet har sedan analyserats genom korrelationsanalys och presenteras tillsammans med resultatet.Resultat & slutsats: Studiens resultat visar på förekomsten av flertalet skillnader och likheter vad gäller hantering av valutarisk som kan kopplas till segmenttillhörighet. Den slutsats som dras i studien visar att benägenheten att skydda sig för rörelseexponering mot valutarisk och att hantera valutarisk internt är störst hos företag på Large Cap och att benägenheten att ta hjälp externt vid valutariskhantering är störst hos företag på Small Cap. Gällande förekomsten av storleksrelaterade likheter visar studien att dessa är relativt små.Förslag till fortsatt forskning: Då denna studie är av kvantitativ natur skulle det i framtiden vara intressant att komplettera enkätundersökningen med intervjuer för att ge en bättre förståelse kring valutasäkringsprocessen.
Skapa öppenhet i erfarenhetsregistrering vid Forsmarks Kraftgrupp AB
Denna rapport är resultatet av ett examensarbete som utfördes på Forsmarks kärnkraftverk åt FTQ-avdelningen. FTQ-avdelning på Forsmark ansvarar för erfarenhetsåterföringens ärenden på anläggningen och försörjer organisationen med nya infallsvinklar gällande erfarenhetsåterföringstekniken. För cirka 10 år kom Forsmarks kraftgrupp AB till insikt att det fanns ett behov av att införa en aktiv erfarenhetsåterföringsprocess för att undvika upprepade misstag. Detta resulterade i att en ny avdelning skapades år 2008 med namnet FTQ. Denna avdelning skapade en databas med namnet ERFKA där man började samla in och lagra erfarenhetsåterföringsärenden.
Termisk hantering av litium-jon- batterier i elektriska drivsystem
The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.
