Due to increasing awareness and consumer demands it has become important for companies to develop an economical and environmentally sustainable alternative to traditional petroleum-based plastics. The transition from fossil material to bio based is important for the future of people and planet, still, how the transformation should be implemented is yet unknown. In this report, the possibilities of
This thesis covers specification and development of a distributed measurement system intended for CAN bus. It was completed at Scania CV, Södertälje in collaboration with Lund University. The goal of the thesis is to specifiy and develop a distributed measurement system that helps Scania with acquisition of functional and electrical data. Several topics are adressed such as filtering, at what spee
Designing and developing a software product is a difficult process. The product must be usable and solve the correct problem. At the same time, the underlying code must be well written. Many projects fail to deliver or exceed their budget. This thesis explores a practical approach to software design and development that tries to adhere to both user centered design and agile development. The proces
In gas turbine blade modeling a stable but yet flexible method of describing the blade shape is crucial. Polynomials and B ́ezier curves have previously been used and in this paper B-splines are employed instead. This method removes the need for many of the interior derivative conditions on the curve but special care must be taken when selecting the parameter values and appropriate derivative cond
The wide and increasing range of screen sizes between Android devices makes consumers use them very differently. Large devices (like televisions) are more suitable to view content and smaller devices (like smart watches) are to be used more as a quick controller of the main application. Distributed user interfaces is the concept of utilizing several of these de- vices in one application, so that e
The main goal of this project was to use the Modelica features on embedded systems, real-time systems and basic mechanical modeling for the control of a two-wheeled self-balancing personal vehicle. The Elektor Wheelie, a Segway-like vehicle, was selected as the process to control. Modelica is an object-oriented language aimed at modeling of complex systems. The work in the thesis used the Modelica

With this thesis we want to prove that by using a single formula for picking stocks, Joel Greenblatt’s ‘’Magic Formula’’, it is possible to achieve returns higher than those achieved by a related index. To prove this, we will construct a portfolio, according to “The Magic Formula”, and backtest the portfolio in the Swedish stock market. The test period will be March 1999 to January 2010 and we wil
To continue the development of novel therapeutics to treat bladder cancer, a reliable model for preclinical testing of treatments and studying of the disease mechanism is essential. Ex vivo culturing of precision cut tumor slices (PCTS) provides a model that can retain the tumor architecture and its tumor microenvironment including the immune cell compartment, but data on PCTS based on bladder tum
The Large Hadron Collider (LHC) at CERN is undergoing a major upgrade to prepare for the High-Luminosity LHC. It will allow for many more particle collisions to occur. Some detectors that make up the LHC experiments must be replaced to withstand the harsher conditions. In particular, the inner tracking detector (ID) of the ATLAS experiment will be replaced by the new Inner Tracker (ITk). Every co
Due to increasing global energy demands and a need to move away from non-renewable energy sources, green hydrogen is now being considered as a possible replacement for fossil-based energy sources. Especially in “hard-to-abate” sectors, such as steel and petrochemical production, and long-distance transport, where the change to renewable electricity is more difficult. Green hydrogen is produced thr
A lack of somatostatin expressing interneurons (SST INs) is known to be a factor in several neurodegenerative and neurospsychiatric diseases, such as Alzheimer disease, Parkinson’s disease and schizophrenia. Being able to efficiently obtain SST INs in vitro could enable a greater understanding and better treatment of these diseases. The development of SST INs is not yet fully understood, but it is
The use of antenna arrays allows for direction-of-arrival (DoA) estimation in a radar system. The antenna elements in an array are conventionally positioned equidistantly on a grid, but they can also be placed relatively freely to form sparse antenna arrays. These non-conventional layouts could potentially offer improved DoA capabilities. In this work, a particle swarm optimization algorithm has b
This thesis studied the recording methodologies of conducting unannounced evacuation drills to enhance the understanding of evacuation behaviours and performance within the Complex Muon Solenoid (CMS) cavern at CERN. The primary objective was to validate the CMS underground evacuation simulation model for planned evacuation and compare various data collection methods. An unannounced evacuation dr
Preeclampsia (PE) occurs in up to 5% of worldwide pregnancies. It is a complex disease characterised by sudden onset hypertension, and it is harmful to the mother as well as the growing baby, accounting for 40% of fetal deaths worldwide. The disease can be divided into early and late-onset PE, defined as diagnosis earlier or later than 34 weeks of gestation. Despite decades of research, the cause
We present a data-driven proof of concept model capable of reproducing expected counterparty credit exposures from market and trade data. The model has its greatest advantages in quick single-contract exposure evaluations that could be used in front office xVA solutions. The data was generated using short rates from the Hull-White One-Factor model. The best performance was obtained from a GRU neur
With the ambition to contribute to a sustainable development, this project started with aim to recycle fiber boards. The idea behind the project is to take lose fibers that come from waste product or simply just worn out fiber boards, and make them into new fiber boards. In order to achieve this, a binder is needed to hold the boards together. The aim of this thesis was to evaluate different binde
The food industry is facing challenges in responding to the climate crisis, and research highlights the potential of using Business Intelligence & Analytics for organizations sustainability efforts. The aim of this study is to holistically map through the affordance lens, what capabilities organizations in the food industry may potentially gain by using BI&A for sustainability. The study i
