In times of increased environmental awareness, there exists a desire to not only build new environmentally friendly and renewable power generating units, but also to increase the efficiency of all existing technology. Wind power is such a renewable and environmentally friendly technology. Wind turbines and wind power have made giant leaps in the world in the past years, with an almost exponential
Wind energy has been used by mankind since ancient times and the last decades have seen large technological advancements in the field of wind turbines. One technology, although not very common, for harnessing the energy in the wind is the vertical axis wind turbine (VAWT). These types of turbines have not been as successful as the horizantal axes wind turbines (HAWTs) regarding efficiency and comm
PV power production is becoming more and more common and one can easily imagine that a so called boom is near in southern Sweden. As the distribution grids are designed for power flow out to the households, and not the other way around, the question is what will happen that sunny day when the households in a neighborhood produce more electricity than they consume. This master thesis project was ca
In today’s housing market, open house plans are requested increasingly. This puts a demand on the beams being used to manage longer spans and is therefore exposed to larger loads. To manage these larger loads, one solution is to increase the beam dimensions. Because of demands to fulfill standardized measurements for doors, ceiling heights and roofing heights, there is not always room for the beam
Studiens syfte var att studera hur medarbetare förhåller sig till organisationsförändringar och vilken betydelse sådana förändringar har för den egna arbetsrelaterade identitetsutvecklingen. Semistrukturerade intervjuer genomfördes med fem medarbetare från fem olika organisationer med erfarenhet av att genomgå förändringar. Intervjumaterialet analyserades med tematisk analys, vilket resulterade i The aim of this study was to explore co-workers’ approach to organizational change and the meaning of those changes related to their own work-related identity development. Semi-structured interviews were conducted with five co-workers from five different organizations who had experienced major organizational change. Thematic analysis was used to analyze the data, and six main themes were identifie
Loans play an important part in how individuals fulfill their goals in the Swedish society. It makes it possible for people to buy a house or get an education, things that might have been impossible without the possibility of taking a loan. A loan also comes with obligations and restrictions on the loan takers life, paying off a loan can take a lifetime and it requires that the loan taker become s
Smart grids have been proposed as a way to increase grid robustness and reduce consumption peaks and at the same time decrease electricity costs for the end users. This thesis aims to develop generic models for smart grids focusing on smart houses which are used to test if it is possible to reduce consumption peaks, decrease electricity cost and at the same time increase grid stability. Models hav
Electrical machines in electrical vehicles are sometimes put under a lot of stress when for example climbing an uphill road. In order for the machine to cope with the heat generation that comes of running extended periods of time near or at peak power one needs a highly developed cooling system. At the division of Industrial Electrical Engineering and Automation (IEA), located at Lunds Tekniska Hö
Abstract Future climate change scenarios project a water temperature increase of 2 to 5 ˚C for the upcoming 100 years. Simultaneously, north temperate zones will face precipitation changes that will ultimately enhance humic content and water colour in freshwater systems. I hypothesised that increased temperature and water colour would benefit the grazing activity of mixotrophs, and the dominance
As a stage in the development of the next generation of wheel loaders, all systems are evaluated in order to minimize the energy consumption. This master thesis aims to investigate the energy consumption for four linkages with different design. It will also investigate how the energy consumption changes when an electro-hydraulic compensation is added in order to keep the load parallel and what the
To be able to change gears in a transmission it is necessary to remove the torque when disengaging and engaging gears in order not to damage the teeth of the cogs. If the driving torque from the engine to the wheels is interrupted for a longer period of time it can be perceived as very uncomfortable for both the driver and passengers in the vehicle. A gear change can be divided into three main sta
Problem formulation: Recent results from the European Food Information Council’s consumer research on nutrition information and food labelling revealed that most consumers have little understanding of the nutrition information found on food products, feel that there is little authority regulating these matters and wish for a more trusted source of information and regulation and lastly it was found
Denna uppsats slutsats är enligt vår mening att företagen till viss del följer upplysningskraven enligt IAS 36 p. 134 men eftersom det är ett principbaserat system leder detta till att upplysningskraven blir en tolkningsfråga. Detta gör att företagen tolkar upplysningskraven på olika sätt och medvetet som omedvetet i kombination med brist på kompetens, döljer information för att konkurrenterna int
Syfte: Syftet är att belysa hur ett belöningssystem lämpligen bör utformas så att önskade effekter uppnås. För undersökningen använder vi fallföretaget Thule. Metod: En abduktiv ansats väljs för arbetets förhållningssätt till arbetsprocessen, medan en kvalitativ fallstudie anslår riktlinjer för empiriinsamlingen. Teoretiska perspektiv: Vi använder teoretiska kriterier för utformning av belöningssy
