The growth of tissues and organs in plants is governed by the morphogen auxin coupled with the membrane protein PIN, which together generate patterns that guide development. Systems of this kind have been studied extensively in experiments and computational system biology models. This thesis builds on that work by introducing a stochastic version of these models to examine differences between stoc

Innovationshöjden för automatiska skjutdörrssystem under de senaste årtionden har resulterat i högteknologiska automatiska skjutdörrar, där tillbehören och användargränssnitten inte har utvecklats i samma utsträckning. Det har lett till att programväljare för skjutdörrar blivit omoderna och svåranvända för användarna. Syftet med denna masteruppsats var att tillsammans med ASSA ABLOY Entrance SysteThe innovation of automatic sliding door systems over the past decades has resulted in high-tech automatic sliding doors, where accessories and user interfaces have not been developed to the same extent. As a result, operating mode selectors for sliding doors has become outdated and difficult for users to operate. The purpose of this master’s thesis was to propose a new design for operating mode s

Special hatha yoga classes for musicians and variations of postures (asana) in normal yoga classes. Why and how to apply the different branches of hatha yoga in a yoga class. Practicing breathing exercises (pranayama), concentration (dharana)/meditation (dhyana), postures (asana) and relaxation (savasana). Safe physical exercises without pressure/bodyweight on hands and wrists. I chose postures co

Physical phenomena that are unexplained by the Standard Model (SM) of particle physics, are the subject of the area of research known as physics Beyond the Standard Model (BSM). BSM physics contains many Dark Matter (DM) theories which have emerged; from particles such as axions, neutrinos, and Weakly Interacting Massive Particles (WIMPs), to primordial black holes and others. The range of exper

Med ökande koncentrationer av koldioxid (CO2) i atmosfären kan energieffektiva tekniker för koldioxidinfångning (CCS) bli viktiga för att växthusgasutsläppen ska minska. Rapportens syfte har varit att experimentellt bestämma och utvärdera fyra egenskaper hos lösningar av vatten, dimetylsulfoxid (DMSO) och aminoalkoholen 2-amino-2-metyl-1-propanol (AMP) som ska användas i en pilotanläggning. Vid inWith increasing atmospheric carbon dioxide (CO2) concentrations, energy efficient carbon capture and storage (CCS) technologies could prove important to enable reductions in the global CO2 emissions. The aim was to investigate a novel, non-aqueous, and precipitating chemical absorption system of dimethyl sulfoxide (DMSO) and 2-amino-2-methyl-1-propanol (AMP), which forms solid carbamate salt cryst

The presented thesis focuses on dynamics of capital structure decisions of financially constrained and unconstrained firms listed on Stockholm Stock Exchange. It examines the effect of the global financial crisis on the corporate financing decision. The first chapter introduces the topic, discusses its importance and outlines the contribution to the empirical research. The second chapter the relev

Flooding of urban areas is a worldwide problem as cities grow and the amount of impermeable surfaces increase generating more surface runoff. In the Zambian city of Ndola, the capital of the Copperbelt Province, flooding occurs in some parts of the city especially on Dag Hammarskjöld Drive at the underbridge, which has been flooding every rainy season consecutively for 8 years now. The main object

The production of single cell biomass by the collaboration company in this project for use as a meat alternative is a potential source of sustainable alternatives to functional ingredients for the food industry. With its high protein content, creating a protein isolate from the single cell biomass became interesting and a study of single cell protein functionalities could offer a possibility to in

In Sweden, what we eat accounts for about a third of the consumption-based greenhouse gas emissions, and there is strong evidence that the most effective way to reduce emissions is to switch to a more plant-based diet. A shift is currently underway in the Swedish food system; the market for plant-based products is showing an exponential growth, coupled with, for the first time since the 1950s, a d

The growing number of African Presidents on Twitter affirms that media, in all its forms, will always play a fundamental role in contemporary politics. Moreover, based on its face value, the presence of Presidents on Twitter could suggest that citizens are gaining unprecedented access to their president. But, this thesis contends that the newness of Twitter should not blind us into thinking that t

The engineers at Westinghouse Electric Company have developed a new nuclear fuel design called TRITON11™, which will be used in Boiling Water Reactors (BWR). This project has been to develop a test program and an assembly fixture for TRITON11™. The test program can not be fully presented in this repport due to confidentiality. The test program is for the first scoping test that will be performed o

A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was succes

The phase field method emerged as a tool to solve free boundary problems with a sharp interface. In previous methods, this involved the computationally inefficient and complicated tracking of a moving interface. The phase field method overcomes this limitation by introducing an auxiliary variable called the order parameter which varies continuously over the whole domain and takes on finite values

Despite the increased focus on sustainable urban development both within academia and in urban planning practices, authors seem to agree that we are mostly continuing business as usual and are not embarking on different socio-environmental trajectories. On the contrary, such urban sustainability practices can often lead to processes of displacement and gentrification, thus worsening the conditions

När man jobbar med stora pogrammeringsprojekt är ett av de stora problemen att skriva koden så den går att underhålla. Skriver man kod som är lätt att underhålla är det också enklare att göra tillägg, ändringar och åtgärda problem. I detta projekt har två stora, liknande projekt undersökts för hitta likheter i koden. Om likheterna kan sammanföras till en generisk lösning kommer koden att vara lätWhen working with large programming projects, one of the major problems is to write the code so it can be maintained. If you write code that is easy to maintain it is also easier to extend, change and fix bugs in the code. In this project two large, similar projects were investigated to find similarities in the code. If the similarities could be brought together in a generic solution, the code wo

A lot of money is being spent by the governments all over the world in developing and deploying Government to Citizen (G2C) e-government applications. These applications serve the purpose of providing better civic services to the citizens. The success of such applications is frequently heard and witnessed in the developed countries but there is a prevailing concern about the success and adoption o

The thesis is done for the company Gambro which manufactures dialysis products worldwide. The idea of this thesis is to investigate weaknesses of the communication protocol which is used in one of the Gambro dialysis machines, Prismaflex and thereby investigate opportunities to improve the system by using other protocols. The thesis is divided into three major parts. They are the study of Prismafl
