Syftet med denna masteruppsats är att implementera en tidigare modellerad kromatografisk adsorptionsprocess från MatLab till Modelon Impact, en simuleringsmjukvara. Modelon Im-pact använder sig av Modelica som syntax som i sin tur är användbart för skapandet av stora system av sammankopplade modeller som kan fungera i olika konfigurationer. Implemente-ringen är lyckad och gjord stegvis under projeThe aim of this master thesis is to implement a previously modeled chromatographic adsorp-tion process from MatLab into the Modelon Impact, a simulation software. Modelon Impact is using Modelica as language syntax that is useful for creating a large system of interconnected models that has the potential to work in different configurations. The model is successfully implemented and done in a step-

Tillverkning av batterier är en mycket komplex process och det är en process som Saft AB är väl förtrogen med. För att kunna producera det antal batterier Saft AB gör måste de se till att alla led i produktionen håller en viss standard. Detta projekt hade i mål att utveckla ett användarcentrerat, interaktivt verktyg för Saft AB med förmågan att övervaka och analysera data som samlas in av sensorerThe production of batteries is a substantially complex process, and it is a process with which Saft AB is greatly familiarised. In order to produce the number of batteries Saft AB does, they need to ensure that all stages of production adhere to a certain standard. This project’s purpose aimed to develop a user focused, interactive tool for Saft AB with the capability to monitor and analyse the da

Cell handling is an important aspect of biomedical research, as an accurate cell media composition and cell viability is paramount for successful studies. Specifically cell washing, the replacement of the liquid media in which the cells are dispersed with another liquid media, has been studied in this thesis. An acoustofluidic device called the AcouWash, by AcouSort AB, which utilizes the combinat

‘Smiling in your brother’s face is an act of charity’; said prophet Muhammad (ALLAH’s peace and blessings be with him). Amelogenin (Amg) is one of the most important proteins that are responsible for perfect tooth formation giving us that beautiful smile. Amelogenin has multifunctional characteristics like wound healing, cells proliferation induction, anti-inflammatory, anti-infectious and signal

Hadfield steel, which is a high-manganese steel alloy, is commonly used as liner for various types of rock crushers. It is used in this application due to its high toughness in combination with its high work hardening ability. Toughness is important for resisting the high impact from rocks during processing. However, the high stress gauging abrasive wear is still significant. This can lead to prod

Med sin ökade tillgänglighet på den kommersiella marknaden har eye-tracking blivit ett allmänt tillgängligt system för att analysera ögonrörelser. Detta har öppnat upp för nya möjligheter för utvärdering av usability inom humancomputer interaction, som tidigare har varit dyrt, tidskrävande och ofta utfört baserat på dåligt dokumenterade standarder och mål. Tidigare forskning har visat att eye-tracWith its increased availability on the commercial market, eye-tracking has become a widely accessible system for analysing eye-movements. This has opened up new possibilities in evaluation of usability in human-computer interaction, which has had a history of being expensive, time-consuming and often performed based on poorly documented standards and objectives. Previous research has indicated the

This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. The positive characteristics in stainless steel are inversely correlated to grain size, characteristics such

During recent years, advancements in mobile technology have enabled the development of quadcopters and unmanned aerial vehicles (UAV) to the point where their size and maneuverability enable indoor flight. In such GPS-denied environments, accurate positioning is a challenge which poses difficulties during flight, navigation and landing. Such positioning systems exist, but are often expensive or re

This project is inspired by my own journey of house hunting in 10 cities across 3 countries in last 10 years and the search continues These experiences have made me curious to explore the urban dynamics of this never ending housing demand in cities across the globe The thesis examines the parameters associated with rental housing deficiency in Berlin a city that offers diversity and opportunity at

More than 400 million people in the world have type 2 diabetes, making it one of the most common diseases internationally according to the World Health Organization. Thiazolidinediones (TZDs) is used to treat type 2 diabetes since it increases the sensitivity of insulin in peripheral tissues. The knowledge about the mechanism how TZD works is limited which has resulted in patients getting serious

The purpose of this paper is to find possible measures to tackle algorithmic collusion, caused especially by pricing algorithms, from the perspective of competition law. This paper does not intend to analyse all possible measures that may exist, but rather, focus on a few measures that are seen reasonable. Before proceeding further to analyse these possible measures, the concepts of algorithms and

Aim: The aim of the study is to characterize the dependency of image quality on absorbed dose for two breast tomosynthesis (BT) systems, GE Senographe Pristina and Siemens Mammomat Inspiration and compare the systems. The image quality was evaluated by different parameters such as: in-plane and in-depth spatial resolution, artifact spread function (ASF) and signal-difference-to-noise ratio (SDNR).

Numerical models of the optical properties of a single nanowire are essential for reproducing the results of the measurements and understanding the optical processes. Intuitively, the properties of a single finitely long nanowire would converge to the ones for an infinitely long nanowire if it is long enough. However, the simulations show that the scattering cross section per unit length of a fini

Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. This thesis covers the development of a low-dimensional model for a l

Financial Repression is increasingly recognized as a viable approach to address high and unsustainable debt levels. Despite its history dating back to the early-mid 1900s, the economic implications of Financial Repression have yet to be fully explored. This paper investigates the effects of Financial Repression, specifically the relationship between two key economic indicators: the exchange rate a

Värmeväxlare är system som ofta används i många olika tillämpningsområden så som kylning, uppvärmning, ventilation eller andra områden där man strävar efter att maximera värmeutbytet mellan fluider. Vanliga tillverkningsmetoder för värmeväxlare inkluderar hydraulisk pressning av värmeöverförande plattor, eller att på andra sätt skapa värmeöverförande ytor av rör, korrugerad plåt eller liknade mateHeat exchangers are systems commonly used in many different applications such as cooling, heating, ventilation, and other areas where maximizing the heat transfer between fluids is desirable. Common manufacturing techniques of heat exchangers include hydraulic pressing of heat-transferring plates, or otherwise creating a heat-transferring area of pipes, corrugated sheet metal, or similar materials

Fat-filled milk powders are manufactured by blending skim milk powder with vegetable oil and these powders have gained a great economic importance. Sensible selection of vegetable oil can help in satisfying both nutritional features and functional characteristics of fat for dairy application. The stability of milk powders can be affected by its composition, mainly the composition of fats which can
