Viskositet och mixerhastighet,bland andra är två nyckelparametrar som påverkar droppuppbrottet i en rotor-stator mixer. En rotor-stator mixer är en av de vanligaste mixrarna som används i dagsläget då de bidrar till ett effektivt droppuppbrott med hjälp av höga skjuvkrafter.Liquid-liquid emulsions can be created using different mixing techniques and the equipment used for processing has a large impact on the final emulsion. Rotor-stator mixers are one of the most commonly used mixers today with multiple application areas. The droplet size is a key parameter during industrial mixing and emulsification, since it influences both the stability and quality of the product.

This thesis set out to examine the process of change from a middle management perspective, in order to gain further understanding of the implications of change on the role of this unique organizational position. In order to do so, this research examined the change process from an in-depth single case study perspective. What was revealed was the existence of multiple roles carried out by the middle

This work is a master thesis preformed by Filip Larsson. The objectives are to measure the aluminium foil used in packaging industry by Tetra Pak. By measuring the surface topography on both sides, the thickness variation will be determined. The measurement results shall then be used in FEM simulations. The Alicona InfiniteFocus microscope at LTH was chosen to perform the measurements. It is a mic

Syftet med uppsatsen är att utveckla förståelsen för hur användandet av accounts i finansiell kommunikation är en del av ett företags krishantering. Vi har valt att studera Vattenfall under åren 2012-2015, den period då nedskrivningarna av Nuon ägde rum och fick stor medial uppmärksamhet. För att uppfylla syftet har vi gjort en kvalitativ textanalys utifrån grundad teori för att identifiera och kaThe purpose of this study is to develop the understanding for the use of accounts in financial communication in corporations’ crisis management. We have chosen to study Vattenfall during the years 2012-2015 when the devaluation of Nuon took place and received a lot of attention in the media. To fulfill the purpose we have done a text analysis based on grounded theory in order to identify and categ

Vad spelar Arktis för roll i klimatförändringarna? Denna avlägsna, och glest befolkade, del av världen utgör faktiskt en viktig del av klimatsystemet. Arktis spelar en betydande roll i kolets kretslopp; vilket innefattar såväl koldioxid och metan, två av de viktigaste växthusgaserna. Förändringar i koncentrationer av växthusgaser påverkar hur mycket värme som hålls kvar i jordens atmosfär. VåtmarkMethane is one of the most important greenhouse gases, and the Arctic region plays an important role in its dynamics. Due to limited observations in this remote and often harsh environments, large uncertainties surround the role of the Arctic region in a warming climate. In this thesis, I examine the performance of the three low-cost solid state sensors, Figaro sensors TGS2600-B00, TGS2611-C00 an

This master thesis consists of improving the transportation by bicycle combined with trains, and make it more user-friendly. The project involved developing a portable carrier that can be offloaded from a transport bicycle and reloaded on a train, and then transported further. Once at the final destination of the rail transportation, the box can easily be transferred from the train to a waiting tr

This study investigates the acoustic characteristics and cross-dialectal variation of the diphthongs /ai au oi ui/ in the Nuckö, Ormsö, and Rickul varieties of Estonian Swedish, which have previously only been described impressionistically (Lagman, 1979; Danell, 1905-34). Eight acoustic measures, reflecting the F1 and F2 frequency values at the first (InF1 and InF2) and second (FinF1 and FinF2) vo

Neurala nätverk har visat större och större framsteg de senaste åren. Framstegen beror till stor del på nätverkens alltmer komplexa arkitektur, vilket medför att kraven som ställs på hårdvaran som nätverken ska användas på också ökar. Målet med detta examensarbete är att träna ett neuralt nätverk för ansiktsigenkänning, och använda det på ett inbyggt system med begränsad hårdvara.Machine learning in general, and artificial neural networks in particular, have gained a lot of attention in recent years. Using deep neural networks for classification tasks, such as face recognition, has proven more and more successful over time. The performance increase is partly due to more complex network architectures, and partly due to the use of larger datasets. The increased complexity of

The lack of availability and relevance of both credit ratings and traded market instruments, forces nancial institutions to nd alternative ways to validate the credit qualities of their counterparties. To address this issue, existing bankruptcy prediction models are evaluated and re-estimated. Furthermore a new model is constructed that outperforms the previous models in terms of default classicat

To simulate district heating networks, in this project the simulation environment Dymola was used. The goal was to run simulation of district heating network and at the same time have good network representation to easily change between different models and also change between doing simulation and optimization. Different models had to be created in Dymola and tested to ensure they work accordingly

In recent years the capital requirements for banks have been updated which has complicated the pricing procedure for derivatives. Nordea has developed a proxy model that approximates the risk measure Exposure At Default, which is an important component in the recently updated requirements. The purpose of this thesis is to validate the accuracy of Nordea’s model. In order to fulfill this purpose, m

Conclusions: The findings of this paper suggest that there is a need for banks to adjust their management control systems (MCS) if they are to foster innovations and be truly ambidextrous. The design of the MCS seems to be of significant importance to achieve contextual ambidexterity. This is concluded as we have found tensions between innovative activities and the banks’ MCS, which are designed f

Extrema regn förväntas ske både oftare och slå med större kraft i framtiden enligt prognoser från FNs klimatpanel. Vid extrema regn, eller skyfall, är det praktiskt taget omöjligt att undvika översvämningar i ledningssystemen, då ledningarna inte är dimensionerade för att klara så stora flöden som dessa regn medför. För att minimera skadorna vid översvämningar spenderar svenska myndigheter enorma Forecasts on the climate change are pointing towards an increased amount of extreme rains or cloudbursts in the future. Cloudbursts are already today a big problem. When cloudbursts occur over dense urban areas, flooding occurs. To prevent damage to property and important functions for society, Swedish municipalities spend an enormous amount of money every year. To make sure that the investments a

För att samla stora mängder information om personer, platser och organisationer, behöver vi kunna analysera vanliga texter skrivna i naturligt språk. Detta arbete bidrar till det, genom att känna igen namn och länka dem till rätt Wikipedia-artikel.This thesis describes the process to build an entity recognizer and disambiguator, named HERD. The goal of the system is to find mentions of entities in text and link those mentions to a unique identifier. This system is designed to be multilingual and has versions in English, French and Swedish. I use Wikipedia as a knowledge source of both names and concepts, and Wikidata, a language agnostic,

I detta examensarbete studeras inverkan av pH på konformationsprocesserna i enzym FKBP12 med hjälp av kärnmagnetisk resonansspektroskopi (NMR). Tidigare studier har identifierat två konformationsprocesser i FKBP12, där den mindre befolkade konformationen i den snabbare processen misstänks vara en intermediär konformation mellan konformationerna som deltar i den långsammare processen. I projektet gThis master thesis project reports the dependence on pH of the conformational exchange in the enzyme FKBP12. Previous NMR studies have identified two conformational exchange processes in FKBP12, where the faster process is believed to be an exchange to an intermediate state between the more slowly exchanging conformations. In this project I carried out different NMR experiments across the pH-inte

Today’s rapidly changing environment amplifies the need for companies no matter the industry, to stay on top of their game and not lose market share to competing firms. This is particularly true of companies in mature industries, and therefore, is a worthy area of study and the focus of this thesis. Rethinking Competitive Strategy in Mature Industries is an in-depth, exploratory study, with an em
