Metoder för att undersöka effekterna av naturvårdshänsynen i skogsbruket efter den nya skogsvårdslagen

In 1994 a new Forestry Act was accepted in Sweden. One of its aims was to raise the consideration for preservation of biodiversity. Since this happened over 15 years ago there is now an interest in analyzing if the law has been effective in its purpose. In this study methods suitable for analysis are being investigated. The study contents a pilot study of methods for five parameters that can validate if the law has been followed.

Övergång till helkrossballast : En studie för Strängbetongfabrikerna i Veddige och Herrljunga

This exam report has been developed in association with Strangbetong AB, Sweden.The natural gravel that is being used as fine aggregate for concrete production today is an ending natural recourse and the Swedish government has decided to strongly reduce the extraction from the year of 2020. The only reasonable replacement is aggregates from crushed rocks but this material has other properties than natural aggregates. The concrete manufacturers now have to learn how to use these new fine aggregates in a cost effective way in order to ensure the quality of their concrete production.In this project, crushed aggregates and combination of crushed and natural aggregates have been tested with existing formulas for fresh concrete. The two parameters yield stress and plastic viscosity have been measured which gives a good description of the workability of the fresh concrete. Different methods to make measurements on the dry fine aggregates, has also been tested, to find out if there is any correlations between these parameters and the parameters from the measurement on the fresh concrete..

?Det finns alltid allting att l?ra sig? En kvalitativ intervjustudie om tidigare elevers erfarenhet av l?rande p? apl och betydelsen av apl f?r anst?llning efter anpassad gymnasieutbildning

Andelen unga med intellektuell funktionsneds?ttning som kommer i arbete efter avslutad gymnasieutbildning ?r oproportionerlig l?g. Forskningsl?get visar p? en bild av en marginaliserad grupp i samh?llet som i ?verg?ngen mellan skola och arbetsliv st?lls inf?r en komplex verklighet med flera inblandade akt?rer. Elevernas m?jlighet att under gymnasietiden prova olika typer av arbete n?mns som en av flera framg?ngsfaktorer f?r anst?llning men elevernas r?ster om betydelsen av arbetsplatsf?rlagt l?rande, apl, saknas i stort sett helt inom forskningen. Syftet med studien var att unders?ka hur n?gra elever som avslutat sina studier p? anpassad gymnasieutbildning upplevde och erfor l?rande p? apl och syftet var ocks? att unders?ka deras uppfattning om betydelsen av apl f?r att komma in p? arbetsmarknaden, vilket preciserades i f?ljande fr?gest?llningar: Vilka erfarenheter av och uppfattningar om l?rande p? sin apl-plats har tidigare elever p? anpassat gymnasium? Vilken betydelse anser eleverna att apl har f?r m?jligheten till anst?llning? Studien tog sin teoretiska utg?ngspunkt i sociokulturellt och specialpedagogiskt perspektiv och metoden som anv?ndes var semistrukturerade kvalitativa intervjuer som sedan analyserades tematiskt. Resultatet visade att apl givit studiens deltagare viktiga erfarenheter och yrkesrelaterade f?rdigheter som f?r de flesta lett till syssels?ttning och arbete.

Vilka faktorer f?rklarar kapitalstrukturen och hur deras p?verkan f?r?ndrats under Covid-19? En kvantitativ studie av 214 bolag listade p? Stockholmsb?rsen

Studien visar att flera faktorer har en signifikant p?verkan p? kapitalstrukturen f?r de unders?kta f?retagen, b?de f?re och under Covid-19 pandemin. Analysen identifierade att l?nsamhet, f?retagsstorlek, tillv?xt, tillg?ngsstruktur, likviditet och risk alla spelade en viktig roll i hur f?retag strukturerade sin finansiering. L?nsamhet visade ett negativt samband med skulds?ttning, vilket indikerar att l?nsamma f?retag f?redrar att anv?nda interna medel i st?llet f?r att ?ka sina skulder.

Rekursiv greyboxidentifiering av drivsystem i industrirobot.

In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.

Implementation av FlexRay prototypstack

FlexRay is a new communication protocol which is fast, reliable and flexible and therefore can meet the increasing demands on data communication in the vehicle industry. The protocol is developed by an industrial consortium containing among  others BMW, Daimler Chrysler, Motorola and Phillips. Today (May 2009) Hägglunds is using CAN for data transmission in their systems. CAN is getting obsolete and has difficulties in coping with the increasing flow of communication. In this report FlexRay and its communication capacity is studied.

Klimatförändringarnas inverkan på dimensionerande grundvattennivå

Helsingborg has the intention to build a train tunnel south of Knutpunkten. This report investigates the hydro geological aspects of the project. Questions at issue that will be answered: 1. Which parameters affect the groundwater level? 2. How will these parameters change within 100 years considering climate changes and what will be the consequences on the groundwater level. According to SMHI climate analysis the climate can change causing increasing precipitation, temperature, and a rising sea level.

Habitatpreferenser hos tjockskalig målarmussla (Unio crassus) med avseende på vattendjup och beskuggning.

The thick-shelled river mussel (Unio crassus) is a red listed species classified as Endangered (EN) and is also considered within the Habitats Directive. The distribution in Sweden is fragmented and it is mostly occurring in the south eastern parts. We investigated the presence of Unio crassus in a section of the stream Storån, Östergötland County, from Falerum to the inflow into Lake Åkervristen. The environmental parameters investigated were water depth, bottom substrate, shading, water velocity and the slope over the water surface. In this thesis I have focused mainly on water depth and shading, comparing sites with and without mussels.

Bonus och ägarskap i svenska storbanker

In this master thesis we are trying to investigate whether the heads of the four major Swedish banks are receiving compensation because of their own performance. We have investigated a number of parameters in the reporting and compensation description of Handelsbanken, Nordea, SEB and Swedbank and compared it to macro data.We have used publicly available information from the banks as well as macro data from 1998 to 2009.We have come to the conclusion that the revenue and profits of the banks are heavily influenced by external factors and that there does not appear to be a clear link between a CEOs actions, the reported results for the bank, the shareholder gains and the compensation for the CEO. It appears as if the bonus payments to a CEO may depend more on parameters beyond the CEOs own control than the performance of the CEO..

Övervakningssystem för båtelektronik

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.
