Samband mellan tjockleken hos PVD-skikt och förslitningsbeteendet vid svarvning
This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the Residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).
Gallring med vinkelkran : en jämförande studie av skördarkran med och utan horisontellt ledad vipparm
One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around Residual trees, easing thinning work in dense stands.
The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.
Hur inverkar sömnmedel i form av bensodiazepiner och bensodiazepinbesläktade medel på dagtrötthet och frakturrisk hos äldre?
Insomnia is getting more prevalent with age, both because of natural changes in the sleep pattern and because of increased morbidity. It can cause dysfunctioning and sedation during the day. Therefore it is often treated with hypnotics. It is possible though that hypnotics can cause daytime sleepiness as well, not to mention increased risk of falling and fractures because of sedation and prolonged reaction time. Benzodiazepines and benzodiazepine related drugs, the subjects of this study, are commonly used as hypnotics.
Omkonstruktion av kolvlod : På uppdrag av institutionen för geologiska vetenskaper Stockholms universitet
On ocean beds around the world sinking particles of Residual biomass from animals and vegetation have, over time, accumulated into thick layers of sediment. For researchers these layers of sediment contain valuable information about the earth?s past climate, information that can be used to predict future climate change and to estimate natural vs. human causes of today?s global warming.The Institute of Geosciences at Stockholm University studies sediment cores that have been acquired with an apparatus called piston corer.
Förändring av sväljfunktion över tid hos personer med Parkinsons sjukdom selekterade till Deep Brain Stimulation
BakgrundSväljsvårigheter är vanligt förekommande vid Parkinsons sjukdom och kan i sin mest avancerade form orsaka lunginflammation som påverkar såväl sjukligheten som dödligheten. Kunskapen är bristande gällande hur sväljfunktionen förändras över tid hos personer med Parkinsons sjukdom, endast ett fåtal studier finns inom området. SyfteSyftet med studien var att undersöka den faryngeala sväljfunktionen under 1 års tid hos personer med Parkinsons sjukdom. Vi hade för avsikt att med hjälp av fiberendoskopisk sväljundersökning bedöma sväljparametrarna penetration/aspiration, Residual och sekret. Deltagarnas subjektiva upplevelse av sväljfunktionen bedömdes utifrån självskattning med hjälp av en visuell analog skala.
Mångfunktionella golfbanor : rekreativa och pedagogiska platser
The objective of this essay is, from the golf perspective including the golf courses' physical attributes, golf club management, members of the golf club and golf course designers, to explore possibilities for making existing golf courses more multifunctional. The purpose of this is to increase the understanding for golf courses' role as part of the landscape and comprehension regarding possible opportunities around them to exploit and develop.The increased pressure of population in peri-urban areas has resulted in a greater need for accessible recreation, particularly in the isolated farmland. As a result, land is sometimes used against landowners' will, which is a deficiency that is the basis for many conflicts between farmers and landowners.In the current situation, there is a negative trend in golf with reduced interest and fewer golfers than in the past. As a result, many of Sweden's golf courses have financial problems and are therefore trying to find new ways to avoid bankruptcy. Sweden's existing golf courses occupy about 30 000 hectares of land, of which a very large percentage are located in peri-urban areas.
Vad påverkar en aktieanalystillförlitlighet? : En kvantitativ studie om relationen mellan tillförlitligheteni en aktieanalys och dess innehåll.
A debate in finance is whether a random investment gives the same return as carefully choose and valuing an amount of shares to invest in. Stock valuating Stock valuation is often done by fundamental valuation models, based on the company's underlying character, which tries to put a correct price on the stock. Today there are several different valuation models that can be used for this purpose. Since valuation models are only mathematical, equity research is underpinned by more subjective assessments about the company and its future.The purpose with this thesis is to describe which valuation models that are used by professional stock analysts, but also to see if the reliability on the equity research is affected by the used model to valuing the company. Furthermore, we want to see if the job that?s been done to understand the company, measured by the equity research quality, impact the reliability on the equity research.In this thesis, we have, to achieve our purpose, conducted a quantitative content analysis of 164 equity research done by professional analysts at firms listed on the Stockholm Stock Exchange. With basis in previous research, we have developed a method for determining the valuation model that is used in the equity research, the reliability on the equity research and a framework for assessing the quality of the equity research.In the theoretical framework the valuation models involved in our study are described, previous research on the reliability on the equity research and their practical use.
DELORES: Smartphone som stöd vid beteendeaktivering för depression : en studie av prediktorer för utfall
Syftet med föreliggande studie var att undersöka möjliga prediktorer för utfallet i KBT-behandling vid depression, face-to-face samt i kombination med stöd av en smartphoneapplikation. 88 deltagare randomiserades till smartphone- (n = 45) eller face-to-face-betingelsen (n = 43). Utfallsmåttet var förändring i Beck Depression Inventory-II mellan förocheftermätning, främst beräknat med Residual gain scores. Samband mellan prediktorer och utfall undersöktes medkorrelationsanalyser. Regressionsanalyser med interaktionen mellan prediktor och behandlingsbetingelse genomfördes för att undersöka skillnader mellan betingelserna.
Vaccinationsbiverkningar hos hundar i Sverige
Vaccinology is an ever expanding field. As a member of the veterinary staff it is important to stay up to date with the continuous new scientific data and recommendations that affect the care that our companion animals receive at the veterinary clinic. This paper presents adverse vaccination reactions, their cause, risk factors and suggestions how we can minimize the risk of adverse vaccine events in dogs. Dog owners in Sweden were allowed to answer a questionnaire about adverse events following vaccination. Lethargy, edema and pruritus were among the most frequently seen adverse effects.
Automation i Distributionsnät
As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid.
Momentbärförmåga för semikompakta ståltvärsnitt av HSQ-balkar : En modell för interpolering mellan eurokodens klass 2 och 3
The current standards for design of steel beams are divided into four classes based on the slenderness of cross-sectional parts. Depending on the section class a beams load capacity is either determined by a plastic, elastic or a reduced elastic model. The division between cross-sections calculated by a plastic and an elastic model is today done in a very harsh way with no smooth transition. This leads to a large difference in the calculated resistance for the sections located near the class limits. Elasto-plastic sections are in the current situation calculated as purely elastic and their large plastic reserve is not considered in the current standards.
(O)motiverad Invandrarpolitik : en studie om motiven att frångå invandrarpolitik och införa integrationspolitik
An effective Integration policy is important in Sweden while our government has decided and committed to be a country where everybody will be given the same opportunities. There is a greater awareness in today?s society of integration policy goals such as equal rights, responsibilities and opportunities for all. In a number of areas, however, the disparities between immigrants and Swedish-born citizens are still too large.The Swedish Riksdag decided on integration policy in 1997. The main task for this thesis will be to examine the motive behind the Government's decision to revoke immigrations policy and introduce integration policy.
En fallstudie i företagsvärdering
När en värdering av ett företag skall göras finns det flera olika typer av värderingsmetoder som kan användas. Bakgrunden till den här studien är att uppsatsförfattarna blev kontaktade av ägarna till ett företag som undrade vad deras företag skulle vara värt vid en eventuell försäljning. Det specifika med företaget är att det endast arbetar mot en kund, samt att företaget nästan inte har några materiella tillgångar.Syfte: Syftet är att kartlägga de olika värderingsmodeller som används vid värdering av företag, för att därefter klargöra vilken eller vilka metoder som är bäst lämpade för vårt fallföretag. Detta syftar till att resultera i en värdering av vårt fallföretag.Metod: Vi har använt oss av en kvalitativ metod i form av en grundlig litteraturstudie, samt en genomgång av tidigare forskning. Vidare har ett antal e-postintervjuer genomförts och slutligen presenteras en modell för värdering av vårt fallföretag.Teori: Den teoretiska delen av denna studie består av de värderingsmetoder som beskrivs i den litteratur som finns inom området.
Regressionsmodellering av dynamiska råemissioner från statiska mätningar
By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.
DISA : En prediktionsstudie av vägledd självhjälpsbehandling för depression via smartphone med internetstöd baserad på beteendeaktivering och mindfulness
Syftet med föreliggande studie var att undersöka om trovärdighet och förväntningar på behandling, deltagarens smartphoneanvändning, aktivitet i behandlingen, samtidig ångestdiagnos, initial symtomnivå på depression samt demografiska egenskaper kan predicera behandlingsutfallet i en depressionsbehandling via smartphone med internetstöd utifrån beteendeaktivering och mindfulness. 81 deltagare randomiserades till antingen beteendeaktiverings- (n=40) eller mindfulnessbetingelsen (n=41). Huvudutfallsmåttet var förändring i BDI-II mellan för- och eftermätning mätt med Residual gain scores. Korrelationsanalyser genomfördes för att undersöka samband mellan prediktorer och utfallsmåttet. För att analysera skillnader mellan grupper gjordes regressionsanalys på interaktionseffekten mellan prediktor x grupp, samt envägs-ANOVA.
