Deltack, Blanket Study

There are two objectives of this study.The first one was to study the new instrument Deltack fromPrufbau, and with the new knowledge, study the interaction between blanket and paper.Deltack is a new instrument to measure the ink splitting force. Blankets from an earlier study doneby GATF have been montered on 12 different Deltack print forms and those have together with Deltackbeen the base for this project.This study together with information from GATF?s study shows that some of the blankets have ahigher capability to adsorb ink. Those blankets generate a sharper shape on the force curve, they havea lower dot gain, but they print not as good solid..

Detektering och Undvikning av Singularitet i ARES Haptic Enheten

Inom utvecklingsområdet haptic är det fria arbetsområdet för singulariteten viktigare änsjälva singulära punkten när det gäller haptic-mjukvaran, då användaren spontantförflyttar verktyget för enheten och inte fritt kan planera en bana för att undvikasingulära punkter. En singulär punkt i arbetsområdet tenderar att skapa komplexaförhållanden såsom oändliga krafter och moment i styr- o reglerteknik designen, som ären viktig del i haptic-applikationen. Det huvudsakliga syftet med denna studie var attupptäcka och undvika olika typer av singulariteter i olika delar av arbetsområdet ochsamtidigt optimera processtiden i ARES haptic enheten. För kartläggning av det friaarbetsområdet för singulära punkten används simulering och beräkning avarbetsområdet för ARES haptic enheten. Simuleringen beskrivs med hjälp av tvåmetoder, där den ena metoden är aritmetiska intervallberäkningar för parallellarobotstrukturer och den andra metoden bygger på att samla in stora mängderinformation om arbetsområdet genom simulering.

Efficient hedging in an illiquid market

Vattenfall hedge its future electricity production in order to decrease fluctuations in theresult. Hedging can in a simplified way be described as selling the future electricity deliveriesin long-term contracts so that the future price of the delivery becomes fixed. The contractsused are electricity forwards traded at the Nordic electricity market Nord Pool. Animbalance between buyers and sellers can lead to a situation where the forward price notequals the expected spot price. The difference between the forward price and the expectedspot price is referred to as the market risk premium.

Farmers preferred end-values related to their use of forward contract : a means-end chain analysis

Today?s farmers are constantly affected by the fluctuating world market prices on grain and thereby the price risk that comes with the price fluctuations. The volatile prices of grain increase the price risk within the business, which in turn affects the profitability of the business. The fluctuating prices together with the increased price risk within the farm business have opened up the market for hedging instruments. In this master thesis project, the aim is to identify the underlying end-values of 30 Swedish farmers? related to their choice of using hedging and the product; forward contract.

Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

En jämförelse av hållningen mellan kvinnor som nyligen har fött barn och kvinnor som aldrig varit gravida

The purpose of this study was to compare the body posture among a group of women who recently have given birth (subjects) and a group of women who never have been pregnant (controls). The comparison was done between the two groups using the Comprehensive Body Examination (CBE) according to Bunkan. In the study participated 24 women, 12 who recently have given birth and 12 who never have been pregnant. The results showed that the body posture differed between the two groups. The subjects differed more from satisfactory jointpositions than the controls.

Hållbarhetsredovisning : En historisk utveckling

Background: The latest development within the business world has been characterized by deregulation and globalization which has made the company bigger and even more influential. The increased power has resulted in a shift of responsibility for the community from the public to the private sector. (Steinholtz och Löhman, 2003) There have been many trends regarding what accountability includes and how financial accounting can be complimented in a useful and reliable way. Some trends have come to stay whilst others have shown to be less successful or the world has not been ready for them. (Larsson, a, 2002) Purpose: The purpose with this paper is to look at the historical development towards accounting for sustainability and to investigate what factors that might have hade an impact on this development.

Resebloggens relevans - innehållet som fångar läsaren

This study investigated whether in-situ audiometry, delivered via hearing aids, is a better option as a basis forprescribing hearing aid amplification, compared to conventional audiometry. By examining the real ear insertgain (REIG) in 29 ears (18 subjects), that had been fitted with a hearing aid programmed using both conventionalaudiometry and in-situ audiometry, the study looked at whether in-situ audiometry based prescription is closer tothe NAL NL1's fitting target than audiogram based prescription. The hearing aid Siemens Pure 7mi with speakerunit M was used on all participants. The results showed how in-situ audiometry based gain at certain frequenciesis more consistent with the target curve, especially at 1000, 1500, 2000 and 4000 Hz. It was not establishedwhether the findings of the study were statistically significant.

Stress i byggbranschen : Orsak till stress i byggbranschen samt förslag på åtgärder

Stress and burnout are two words that are commonly occurring in many contexts today. More and more people experience that they are stressed and that they does not feel well. The long term sick -leave increases as a consequence of people being burned out. These phenomena prolong over all ages, sexes, classes and professional categories, which probably means that the construction industry would not be spared.  In the construction industry, stress and bad health are no new phenomenon, already during the 1970s and big parts of the 1990 s, the construction sector were exposed to the phenomena.A sector that has a large turnover annually cannot presumably be faultless.

Den sköna nya tiden 2013

2013. The brave new time.We constantly look forward in time. There is a need today to constantly renew, replace and update almost everything in our lives. Although often stressful, these continual changes and upgrades can open up new possibilities and even be seen as enjoyable and stimulating.Values, opinions, and everything we create, is based on an experience of the past and predictions of what the future might be. I want to take advantage of these thoughts and find out how they relate to our exchangeable culture.

Deferred Rendering : Jämförelse mellan traditionell deferred rendering och light pre-pass rendering

Då scenkomplexitet och ett högre antal ljuskällor blir vanligare inom spel har ett behov av algortimer för att hantera dessa scener, med bra prestanda, uppståt. En allt vanligare algoritm för detta är Deferred Shading. Rapporten utvärderar två olika metoder för Deferred Shading (traditionell Deferred Shading och Light pre-pass rendering)..

Beräkning av återmatad bromsenergi på Malmbanan

Energi är en resurs som måste användas effektiv för att undvika onödig negativ miljöpåverkan och utgifter. Återmatning från nedåtgående malmtåg till uppåtgående malmtåg leder till en effektivisering i energiutnyttjande. Beräkningen av den återmatade energin utgår ifrån tågets lägesenergi och förlusterna från räls, lutning, vind och kurvor. Totalt kan återmatning av energi ge en besparing på 20 % för enkelspår och 20 % respektive 21 % för dubbelspår. Dubbelspår kan ha mer trafik än enkelspår men förhållandet mellan konsumerad och återmatad energi är i princip den samma.

Äldres individuella behov borde ligga till grund : En studie om dagstidningars framställning av äldre med omsorgsbehov

This bachelor´s thesis wants to look closer at librarians´ experiences of comics, manga and graphic novels. In order to bring these experiences forward qualitative interviews and the method of phenomenography was used. The material was then examend againstna theory of previous research, revealing that the problems librarians in Sweden face with these media are largely the same as the problems faced by librarians in other parts of the world. It also became clear that the participating librarians held a positive attitude to the presence of comics, manga and graphic novles in their libraries..
