This thesis work is part of a larger project with final goal to be able to measure the oxygen concentration in the lungs of infants, using non-invasive laser spectroscopy. This thesis is specifically dealing with simulations of light transport through the upper body of infants, as well as constructing a tissue-like model (phantom) that can be used in experiments. The goal is to use these simulatio
Perovskites have proven to have very promising properties applicable in future higher efficient technological devices such as light emitters and solar cells. In further development of perovskite solar cell devices there are however serious material drawbacks such as instability and toxicity, causing the perovskite research community to question if and how these obstacles can be overcome. In this
Bees are mostly diurnal insects and rely on their vision to perform daily tasks. Their apposition compound eyes play a big part in regulating vision. To improve our knowledge of how vision functions, we will observe these apposition compound eyes using micro CT. The aim of this report was to compare two different methods of preparing and scanning the bees. The first method uses resin to embed the
As the most diverse group of animals in the world with more than a million describes species, insects varies in many aspects of their ecology. Bees are insects that can be found in many different habitats across the world. Some live in open landscapes while others live in denser vegetation, some are active in the night while others are active during the day. Since bees use their vision to navigate
Ekosystemtjänster är ett viktigt begrepp för att sprida förståelse om naturens värde för människan och det finns ett flertal kategorier av tjänster som naturen bidrar med. Vissa tjänster är mer aktuella än andra beroende på vilken miljö man fokuserar på, och i detta arbete ligger fokus på att utvärdera reglerande ekosystemtjänster i stadsmiljön då grönytor i dagens städer hotas allt mer och mer av
The language learning process by third age learners has recently become a field of interest for linguistic research. However, it has been studied mostly regarding psychological and cognitive considerations (stress, motivation, attention, memory, etc.), rather than according to language internal factors. The present study aims to provide a contribution by investigating the mastery of Italian gramma
Technological advances in cloud technology, robotics, and telecommunications could provide for new and interesting applications. This thesis investigates how a combination of these areas can be utilized in order to improve performance in a smart manufacturing setting. In doing so, an architecture based on the Actor model has been used. The proposed architecture is both described from a theoretical
China’s rapid urbanization process has included a large scale migration of rural labor migrants to the cities since the 1990s. The education problem of their children who migrate together with them also becomes increasingly prominent. In order to allow migrant children enjoy a fair education, China introduced the "two oriented" policy in 2001. This policy clarifies that the management re
This MSc thesis covers the development of a Modelica model of an engine liquid cooling system for the trucks manufactured by MAN Truck & Bus AG. The mathematical assumptions used for transcribing existing models are described and the reasoning behind the modeling process is provided. The separate component models are validated with two sets of input signals. Primarily with a dynamic, transien
Renal diseases are an increasing problem worldwide and when kidney transplantation is not possible, dialysis treatment is the solution. An increasing number of patients choose to perform their dialysis treatment at home by implementing the dialysis machine and a water purification system in current electric and water supply, so called home hemodialysis. The quality of the water used for the prepar
The competition in the power plant business is today extremely hard and all manufacturers’ technics to achieve as low heat rate in sold power plants are very refined. This in combination with high fees for companies that can’t achieve what’s agreed in the contracts has made the feedback process very important in order to keep the business successful. A fossil power plant has therefore been evaluat
