Kapitalstruktur i svenska aktiebolag : En studie om påvisade faktorers egentliga påverkan på kapitalstruktur
In order for companies to be competetive on the market, there?s a need of capital. If a company is in a need of capital to make major investments and isn?t able to prioritize internal funding, the priority will be external financing with safe securities; loans. How companies should prioritize the allocation between equity and debt, which together form value, leads us to the subject of capital structure.

Shock absorber units play a key role in establishing the driving dynamics and performance of automobiles. Öhlins Racing has manufactured high-tech automotive shock absorbers for over 30 years. Öhlins Racing?s advanced technology has contributed to over 200 world championships in automobile racing. Öhlin?s manufacturing process has long utilized automated fluid filling equipment during the final shock absorber unit assembly stage. The filling process consists of vacuum pumping the shock absorber unit and subsequent transfer of fluid. Vacuum pumping is necessary to remove residual air from the shock absorber unit prior to initiating the liquid filling stage. The presence of undesirable gases drastically compromises the performance of a shock absorber. The filling degree, defined as the final ratio of air to oil, is determined by the specific filling protocol as well as the specific equipment utilized.The current investigation aims to develop a viable technique to accurately determine residual air content in shock absorber units. If the filling degree can be appropriately quantified for a specific manufacturing process, then the air/oil ratio may be quantitatively related to shock absorber performance. The utilized measurement method must be completely integrated into the manufacturing process to guarantee shock absorber performance specifications according to the manufacturer?s standards. By utilizing the measurement method developed in this work, the manufacturing process, manufacturing equipment and product specifications can all be tailored to provide improved filling conditions.The developed measurement method provides accurate quantification of the filling degree under a wide range of processing conditions. The method establishes the relative quantity of air in the shock absorber unit by performing in-situ compressibility tests. The fill ratio can be controlled and varied by manipulating the vacuum pressure exerted during the filling process. Performance tests, however, indicate no correlation between filling degree and unit performance..
Problem i högt fuktbelastade byggnader : Riskbedömning med hjälp av WUFI
Många av Sveriges badhus byggda i slutet av 1900-talet börjar idag visa tecken på kraftiga fuktskador på grund av extrema inomhusklimat. Denna rapport förklarar den allmänna problematiken kring högt fuktbelastade byggnader och berör det fuktskadade badhuset Aquarena i Katrineholm. Extrem noggrannhet krävs vid montering av ångspärr i en konstruktion, speciellt vid högt invändigt fukttillskott. Optimal placering av fuktspärren i konstruktionens varmare del innebär att fukt aldrig tillåts kondensera och därmed minimeras risken för fuktskador och negativa konsekvenser. Verkligheten visar också att om kunskaper om fukt och fuktskador prioriteras redan i ett tidigt stadium under projektering kan många hundratusentals kronor sparas. Beräkningar av fukttransport har gjorts för tidigare ytterväggskonstruktion i Aquarena (den som drabbats av skador) och nybyggd ytterväggskonstruktion (nyframtagen till återuppbyggnaden) i datorprogrammet WUFI Pro 4.2 och analyserats i WUFI Bio 3.0.
Systemanalys av skogsbränsletransporter :
At the end of 70s and the beginning of 80s, 18 terminals was built and used for chipping wood residue from clear cuttings. Most of the terminals was terminated before the 2000s but with the high oil- and energy prices that we can see today there might be a place for these terminals again. The goal with the study was to analyze and compare economical differences between 5 different logistical systems, collected data was used with a set of formulas. The systems include long range transport of slash, chips and bundles. Three of the systems include transport by lorry to industry the last two includes a terminal with access to train transport.
Torkning av vallfrö :
In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the
fields, this is primarily used as feed for livestock. To get a good seed, you need to
handle the crop carefully from planting to delivery. The part that I have been
interested in, is how to dry the harvested seed with out destroying the growth in the
small seed. This is very easily done if you aren?t careful during the drying period.
Pre-treatment of grain for ethanol production during storage
Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.
Kapitalstrukturens effekt på lönsamhet : En studie av svenska företag
In this paper the effect of capital structure on profitability has been investigated among Swedish companies. The essay intends to examine how the relationship between debt and profitability appear among Swedish companies and if the relationship differs between industries. The purpose is to find out how debt affects the profitability of Swedish companies.A quantitative approach has been applied. The selection was made among companies listed on Nasdaq OMX Stockholm, which resulted in a sample of 207 companies. Several regression analyzes has been formed, based on the independent variable debt-ratio and the dependent variables profit margin, pre-tax profit margin, operating margin, return on assets and return on equity.
Dämplindningens inverkan på spänningens kurvform i en vattenkraftsgenerator
Harmonics are a well-known problem that has to be dealt with in the design of thegenerator. Internationally accepted standards limits the amount of harmonics allowedin the no-load voltage. These limits can be difficult to fulfill with integral slot winding,where the number of slots per pole and phase is an integer. The presence of thedamper winding often makes the problem with harmonics even worse and harmonicswith frequencies of order 6q±1 arise with significant amplitude. How the damperwinding is designed affect the content of harmonics in the no-load voltage and the aimwith these ? has been to investigate in which extent design of the damper windingaffects the contents of harmonics.Simulations with the 2-D finite element method have showed that if the damper barsis centered in the pole shoe, the amplitude of the harmonics of order 6q±1dependsboth on the ratio between the stator slot pitch and damper bars slot pitch and if thedamper bars are connected between the poles or not.If the damper bars is displaced with ¼ stator slot pitch alternately, the amplitude ofthe harmonics of order 6q±1 is reduced and the influence of the ratio between thestator slot pitch and the damper bars slot pitch will vanish.
Den vägda nyttjandeperioden och dess effekter på utvalda finansiella nyckeltal: En studie av bostadsrättsföreningars avskrivningstider på byggnader
Housing cooperatives in Sweden practice very long depreciation times for their buildings and assets, subsequently depreciation costs are very low. This study aims at addressing issues relating to potential upward revisions of these costs and the revenue levels needed by housing cooperatives to address these changes, while also providing a detailed summary of some chosen financial ratios under different circumstances. This study's results are based upon recent (2015) market data within the Stockholm region, collected through a manual process and analyzed quantitatively. On average, housing cooperatives EBIT do not cover their financial costs and have low profit margins. The average depreciation time is considerably above what a technical evaluation by other sources may state.
Foderbetor och kogödsel som substrat för biogasproduktion; anaerob mesofil samrötning i labbskala
One of Sweden?s sixteen national environmental objectives strives to decrease the impact on the climate. By 2020, green house gas emissions should be 40 % less compared to the levels of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative.
Elektrisk skorstenständare
Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of renovation. The municipal housing company, Gavlega?rdarna, renovates and improves the energy efficiency at some of it?s apartment buildings in the district Sa?tra, Ga?vle.
?Ärligt talat så har det [tradingen] blivit en skitaffär? : En fallstudie av HQ Bank
The global financial crisis hit hard on banking operations worldwide and the sector fell under considerable scrutiny, with particular criticism directed against the banks' own trading practices. A bank owned by the Swedish financial corporation HQ seemed to go without serious financial damage duringthe crisis.In 2008 Finansinspektionen began a review of HQ's activities and a number of shortcomings were identified. Among other things, HQ's risk management was questioned by Finansinspektionen and further how this potentially affected the valuation of complex financial products.In our paper we have chosen to highlight both national and international laws and guidelines that HQ used for their operations and study if HQ followed those laws and guidelines. We also want topresent the theoretical model used by HQ for the valuation of its European options and how HQ calculated their capital requirements ratio. Our purpose is to show how the valuation affected the capitalrequirement ratio and whether HQ followed the necessary laws and guidelines for the valuation of complex financial products.We have chosen to carry out a case study from a deductive approach.
Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten
Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.
Hjärtfrekvens och hjärtfrekvensvariabilitet som fysiologiskt mått på mental stress hos hästar
SAMMANFATTNING
Denna litteraturstudie syftar till att utvärdera hjärtfrekvens och hjärtfrekvensvariabilitet som fysiologiska mått på mental stress hos häst. För att utvärdera detta har olika artiklar studerats. Artiklarna redovisar studier där hästar utsätts för framför allt mentala stressmoment. Under stressmomenten har antingen hjärtfrekvens (HR) eller hjärtfrekvens och hjärtfrekvensvariabilitet (HRV) registrerats. Hjärtfrekvensvariabiliteten kan omvandlas till ett antal parametrar, bland annat lågfrekvensband (LF) och högfrekvensband (HF).
Referenser i informationsåtervinning: utvärdering av en sökstrategi för citationsindex
In this essay, a search strategy for citation index is studied. The strategy, which is essentially a citation cycle, starts with documents retrieved by a subject search, wherefrom new documents are identified following the network of citations backwards and forwards in time. Based on the theory of polyrepresentation, the strategy exploits overlaps between cognitively different interpretations of the same documents in order to automatically select references seed documents used as a starting point for the forward chaining. The purpose of the investigation is to evaluate the retrieval effectiveness of the search strategy and to find out whether the strategy can be used to expand a subject search with the help of the network of references in order to retrieve new relevant documents. Two questions are formulated: 1a.
