Kappa Control with Online Analyzer Using Samples from the Digester's Mid-phase

In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.

Studier av mjölkbarhet automatiskt mätt i mjölkningsanläggningar :

Milkability or ease of milking, has higher importance today for Swedish dairy cattle producers after the introduction of milking parlours and automatic milking systems. Milkability is the cow?s ability to quickly milk out and be completely milked. There are several measures of milkability available. Today the farmer measures the traits subjectively in relation to the conformation scoring of the cow 30-270 days after her first calving.

De sociala medierna och rättssystemet

 The main purpose is to investigate the main fea-tures of the discourse in the social medias about the legal view on cimes and criminals.                                                The special questions that are investigated are:1)    What specific features characterize the discourse in the social medias?2)    What are the legal restrictions for the freedom of speech on the Internet?3)    What attitudes can you find among lawyers towards the discourse in the social medias?4)    Are there grounds for presuming that the discourse in the social medias can effect the judgement in a special case?         .

En grav är mer än bara en grav... En metodutveckling av tafonomi som redskap att förstå olika anläggningar med djur

This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. My questions also regards to wether a taphonomic analysis of the material could be used to identify treatments as wrapping and contraction of the dogs, but also dismembering and other preparations of the body. The study focuses on the relation between the space of decomposition, disarti-culation of the joints, evidence of wall effect, cutmarks, weathering and signs of postdepositional arrangements.The analysis is based on contexts from the materials Hornborgasjön, Vedbæk, Skateholm I and II, Sjöholmen, Ertebølle, Bökeberg, Bredasten, Löddesborg, Bergsvägen and Röekillorna, dating from early Maglemose culture to Neolithic Battle axe culture.The analysis shows that a closer study of taphonomic processes can be used to identify different structures as graves, offerings, religious and non religious contexts or parts of animals, probably put into the ground as waste.

Framtagande av ny höjdmätningsmetod till försvarets antennhiss 861

This bachelor degree project was carried out at Saab AB Service and Repair, Arboga, Sweden. The objective was to design, construct and implement a new stable and reliable method of measuring the continuous vertical displacement (height) of the military search radar PS861 mounted on a hydraulic powered elevator. The end product needs to be durable enough to be fully operational in the harsh environment of an outdoor elevator shaft and yet as accurate and precise as possible since one of its purposes is to calibrate control equipment. Previously used technique has proven not to meet any of the above mentioned properties.A prototype using a high resolution quadrature output rotary encoder has been developed, allowing a completely digital interface. This new method has been evaluated in laboratory environment where tests have been conducted regarding both reliability and validity.

I morgon blir det börsfall! : En studie om hur olika börser påverkar varandra i fördröjning

SammanfattningTitel: Imorgon blir det börsfall! En studie om hur olika börser påverkar varandra i fördröjning.Seminariedatum: 28 maj, 2012Ämne/kurs: FEK 61-90 Kandidatuppsats i Corporate Finance, 15 poäng Författare: Stefan Koch, Malin Molin Handledare: Hans MörnerExaminator: Kent SahlgrenNyckelord: Anomali, anomalier, veckodagseffekt, måndagseffekt, index, korrelation, S&P 500, OMXS 30, effektiva marknadshypotesenSyfte: Att undersöka ifall en eventuell anomali på det svenska OMXS 30 indexet eller det amerikanska S&P 500 ger en effekt på nästföljande dag på det motsatta indexet. Om en veckodagseffekt kan påvisas och den fördröjda korrelationen mellan indexen är tillräckligt stark kan metoden användas för att generera överavkastning.  Metod: Vi använder oss av en kvantitativ ansats för att med hjälp av statistiska metoder svara på vår problemformulering. De metoder vi har använt är hypotestestning av medelvärden med ett z test, beräknat korrelationskoefficienten mellan de två indexen och utfört en multipel regressionsanalys med dummyvariabler.Slutsats: Genom vår analys kom vi fram till att en veckodagseffekt inte kan påvisas på någon av de två undersökta indexen. En korrelation kunde finnas mellan de två indexen, däremot går det att ifrågasätta om korrelationens styrka är tillräckligt stark att handla utifrån. För att generera överavkastning krävs dessutom att den extra avkastning som genereras med hjälp utav vår metod med korta aktieaffärer överstiger den eventuella transaktionskostnaden som uppstår vid aktiehandel, något vi starkt betvivlar att den gör..

Att våga vara innovativ: En fallstudie om affärsutveckling av befintliga produkter i ett högteknologisk företag

High technology companies in Sweden spend a huge amount of money on research and product development in proportion to what they get back in earnings from their inventions. Product development has traditionally been regarded as much more important than business development. This thesis aims to point out the critical factors behind successful business development processes for high technology companies. We have chosen to make a case study of Hexagon, a highly successful and innovative company within the measurement technology business. Internal and external actors that are important for business development have been identified and interviewed in order to understand how ideas are developed and executed.

Problematik vid analys av fastighetsbolag efter införandet av IFRS

The study describes the problems with analysis of real estate companies after the introduction of IFRS. With the introduction of IFRS (2005) and specially IAS 40 the real estate companies get the ability to appreciate its real estates to real value. With the difference in the accounting, grows the question if it has become some differences for analysts with analysis and valuation of real estate companies. We also look into how well this new standard effect the real estate companies from the view of the accounting quality and its characteristics..

Sortimentsinriktad avverkning

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.

Demonstratortest av gassensor baserad på tryckt organisk elektronik och jonledande papper

Researchers at Karlstad University have developed a method for making paper ion conducting. The reasearchers want to test this technique in various applications and produce products that make use of the ion-conducting paper. Hopefully this will drive the development forward and result in new applications for the ion-conducting paper.This study was to test the possibility of manufacturing a gas sensor of conducting paper along with electrodes of conductive polymers printed on the paper. By comparing the paper sensor with an electrochemical cell in which the electrodes of conductive polymer replaces electrodes of metal and ion-conductive paper replaces the liquid electrolyte in the electrochemical cell, it was hoped that it would be possible to measure the oxidation and reduction reactions that a gas could introduce at the electrodes.It was shown that it is possible to measure a potential difference in the range of 0.3 V to 0.5 V between the electrodes when exposing an electrode to 100% oxygen. The reaction that takes place is relatively slow and the reaction rate is partly due to the distance between the electrodes.Since the sensor can measure oxidation and reduction reactions it is possible that, in further development of a sensor, the sensor can be made ??into a versatile sensor with more applications than gas measurement as there are many more ways to oxidize or reduce the electrodes than by exposure to oxygen.During the study there have been discussions and meetings held with various companies in the sensor industry to be able to specify what the market demands of a sensor made ??of paper and the requirements that must be placed on the sensor for it to be interesting for the companies..

Bostadsbranschens väg in i upplevelseekonomin : Kan fastighetsmäklarens arbete omvandlas till en säljande upplevelse?

The civilization has taken a step from the industry society to a service oriented culturewhere the physical differences between different products have decreased in value for the customers. The differentiation is more about senses, esthetical symbols and design. Modern economy is more and more focused on consuming and produce dreams and lifestyles. Maybe are we ready to face a new era; the society of experiences?Can the trend that is striving towards experiences really be adapted to all markets? This question started our quest to see how the real-estate market would be able to be adapted to this new economy.

Att ragga på de svårflörtade: Om värdet av kampanjsajter för besökare och annonsörer

Campaign websites are a growing Internet based type of advertising, dependent upon the advertisement being actively pursued by consumers. The popularity of campaign websites stands in sharp contrast to the increasing advertising boredom among consumers often discussed in both public media and academic contexts. Despite the increasing importance of this kind of communication, little academic research has been conducted on the subject. The purpose of this thesis is to investigate the value of campaign websites for advertisers and consumers. Through a quantitative web based field study combined with an exhaustive qualitative study, we can draw conclusions concerning campaign websites and contribute with a theoretical framework for this type of advertising.

Hårdhetsvariation i grundvatten längs Badelundaåsen mellan Leksand och Avesta

Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.
