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

Thymidine kinase 1 from tomato (ToTK1) is a newly discovered deoxyribonucleoside kinase (dNK) that has been subject to study due to its in vitro and in vivo properties making it an interesting suicide gene candidate for the treatment of brain tumors. The ToTK1 phosphorylates the nucleoside analogue 3-azido-2,3-dideoxythymidine (azidothymidine, AZT) equally well as its natural substrate thymidine (

In the present study, the enzyme thymidine kinase 1 from tomato (ToTK1) was expressed in E.coli and purified to near homogeneity by means of affinity chromatography. However, purified ToTK1 of bacterial origin displayed no substantial catalytic activity. Expression was also attempted in insect cells using the baculovirus expression vector system (BEVS). Significant TK activities were detected in t

The relationship between business cycles and mortality has been a highly debated subject in the field of economics. The majority of previous studies, using the unemployment rate as the main proxy for macroeconomic conditions, have found ambiguous effects largely depending on how the effect is estimated. This thesis follows the methodology used by Ruhm (2000), but instead applies aggregate data for

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

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

In the airline industry, it is critical for carriers to vary prices offered to different customer groups in order to extract maximum willingness-to-pay from each consumer. This essay investigates a dynamic form of third-degree price discrimination in which prices are strategically adjusted as departure date approaches. It is hypothesized that by including a stochastic element in their pricing sche

Patienter som vårdas på intensivvårdsavdelningen (IVA) är kritiskt sjuka. Inter-nationella samt nationella studier visar på att många patienter kan efter att ha vårdats på IVA, få psykiska besvär så som ångest, depression och posttraumatisk stress (PTSD). En bidragande faktor för att utveckla dessa besvär har visat sig vara obehagliga och traumatiska minnen. Syftet med studien var att beskriva pat
