Sammanställning och fördjupning av begreppet Smarta elnät: En litteraturstudie
I dagsläget har världen en stadigt växande befolkning och där igenom en stadigt växande energiförbrukning. Med en växande energiförbrukning har det under de senaste åren uppenbarats diskussioner rörande samhällets hållbarhet och miljöpåverkan. Samtidigt sker det en kontinuerlig teknikutveckling och människan är mer beroende av konstant elförsörjning än någonsin tidigare. Teknologiska framsteg, tillsammans med önskan att sträva mot ett mer hållbart samhälle med hög elleveranssäkerhet, har mynnat ett begrepp kallat smarta elnät.Till följd av att elnätet involverar en stor bransch råder det delad mening över vad som utgör ett smart elnät. Detta har lett till uppkomsten av olika definitioner och modeller av konceptet. I syfte att skapa en övergripande uppfattning har en litteraturstudie utförts för att sammanställa de huvudsakliga områden som utgör det smarta elnätet.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
Leveransservicens betydelse som konkurrensmedel i apoteksbranschen : En fallstudie om hur Apoteket AB arbetar med leveransservice
During the last years, the pharmacy market undergone major changes. Re-regulation that has been done in 2009 meant that monopoly was unlocked for competition. In a market where firms offer equivalent products, increases the importance of delivery service as competitive tool to differentiate themselves among the crowd. This also applies to pharmacy market where the supplies of goods in large way consist of equivalent products regardless of the company.This case study observes the importance of delivery service in terms of competitive tool on pharmacy market by focusing on a company?s improvement in delivery service.
Till en älskad vän : materia och objekt som medier för överföring
With self-hypnosis as a method, I work with levels of consciousness in relation to practice. Focus lies in the relation between a language of materials and an inner experience. How do material expressions function as mediums of a spiritual matter between a beholder and me? The trance functions as a space for a spiritual contact/communication. Abstract images of crystalline glaze on ceramic tiles are direct results of these acts.
A resource based view of productivity, firm growth and technical management tools : a case study of Swedish large-scale farms
The past and ongoing structural change in Swedish agriculture has led to an increasing
number of large-scale farms. The biological factors associated with large-scale farming
operations may cause increasing variability, risk and reduced yields due to sub-optimal timing
and management of field operations. The theory of economies of scale suggests that largescale
production may benefit from lower costs due to scale efficiencies. Thus, large-scale
farms may face cost reductions in terms of long term inputs factors, e.g. agricultural
machinery.

Expansionsmaskiner istället för strypventiler - en effektivisering
In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.
Prestationspåverkan av flerträdshantering i klena gallringar
The aim of this study is to investigate how multiple tree handling harvesters perform compared to earlier developed standards. The study shows that multiple tree handling harvesters are more efficient in thinnings stands with mean stock volumes less than 0,12 m3fub per stock. The increased efficiency is different for different mean stem classes. In stands with a mean stem volume of 0,04 m3fub per stock, the increase can be as high as 40 percent while it is about 10 percent in stands with a mean stem volume of 0,12 m3fub.
Comparisons have been done between stands that are felled with partly limbed stands and stands without partly limbed assortments. The difference in performance is clear and shows that the partly limbed assortments strengthen the multiple tree handling harvesters positive effects in low dimension thinnings.
Integration av PLM och CAD i komplex produktutveckling : En utredning av Scanias framtida systemmiljö för produktdatahantering
In today's producing companies, there is a high demand on early integrated productdevelopment. One way to facilitate communication between departments and collaborationbetween people and thereby enable early sharing of product information within the companyis to use PLM, Product Lifecycle Management.The CAD environment at Scania is at the moment being upgraded from Catia v4 to Catiav5. In this stage it is important that also the interacting computer systems in Scania?s PLMenvironment are adjusted and in the future join the development. Scania has an idea of howthese systems will be developed as the transition from Catia v4 to Catia v5 is being carriedout.
Beslutsmodell för lagerplacering
The study examined what NHL-teams should improve. This has been done by studying the significant statistics of NHL-seasons, and with linear regression identifying what NHL-teams should do to win many points and thereby get a good placement in the final table. The most interesting result of the study is that the statistics on faceoffs and shots on goal and power play efficiency most seasons where irrelevant for the outcome of a season..

Upplysning enligt IAS 36 : En kvantitativ fallstudie av två branscher
Background: Goodwill has been a hot and debated topic for a longer period of time. Researchers have debated how goodwill should be accounted for and have not come to a solution. In 2005 IFRS standards came which meant that goodwill no longer will be amortized according to plan, but to be put through a yearly impairment test.Problem: A number of disclosure requirements in the financial reports have been made in an effort to avoid companies to account for goodwill differently. Apparently there still is a problem of how companies account for goodwill and there are several studies in the subject. But no one has studied how it is between two different industries, which make this study interesting to execute.Purpose/questions: This study have the purpose to investigate how the industries day to day wares and health care regards the disclosure requirements for goodwill by the impairment tests.
Energieffektivare torkning i diskmaskiner genom ny torkmetod : Utvärdering genom praktiska försök och simuleringar
Världens energiförbrukning ökar ständigt. Detta ger upphov till stora miljöproblem där klimatförändringen är ett av de största problemen. Hushållens energiförbrukning står idag för en betydande del av den totala energianvändningen. Det är därför viktigt att effektivisera hushållens energianvändning för att reducera deras påverkan på miljön. Vitvaror, som står för en stor del av hushållens energianvändning, har en stor potential att energieffektiviseras.
