Sverige genomgår en övergångsfas mellan två olika signalsystem på järnvägen. ATC-2 är det nuvarande punktinformationssystemet som finns på den svenska järnvägen. Detta system ska stegvis ersättas med ERTMS, ett system som ska bli det standardiserade signalsystemet på EU:s järnvägar. Under denna period har Trafikverket i uppdrag av den svenska regeringen att ta fram rapporter som redovisar resultatSweden is currently undergoing a transition phase to a new signalling system on its railway network. ATC-2 is the current point information system in use on the network. The system will gradually be replaced with ERTMS, which will become the standardised signalling system in the European Union (EU). During this period, the Swedish Transport Administration (Trafikverket) has been commissioned by th

Alfa Laval has been using its unique adhesive mixture for over 50 years for bonding of rubber gaskets to the corrugated plates used in their heat exchangers. The adhesive mix is designated GC6 and is composed out of an epoxy component and a phenolic component. GC6 has throughout the years shown exceptionally good performance in both adhesion to the rubber gasket and to the plate with minimal pre-t

Denna rapport innehåller en produktutvecklingsprocess som fokuserar på att integrera ett mjukstängningssystem för skjutdörrar i ett existerande skåp på IKEA. Enheten har idag vad som kallas för guider som håller skåpsdörrarna på plats. Målet är att skapa en enhet som besitter de viktigaste egenskaperna av en guide och av en mjukstängningsmekanism för att kunna ersätta den förstnämnda. Detta görs fThis master thesis includes a product development process focused on incorporating a soft closing system for sliding doors in an existing cabinet at IKEA. A soft closing system prevents the door from slamming into the furniture when closing it. The unit today has what is called guides, holding the cabinet doors in place. The aim is to create a device that possesses all of the crucial qualities of

A stark political system change in Warsaw and an enormous economic spurt have given prominence to private initiatives, leaving behind several public spaces and relevant buildings or at the will of speculative developers. Sports facilities, being one of these public spaces, are having problems of funding, restoration and maintenance, leaving them neglected, though there is a need of them functionin

This paper analyzes the impact of skilled emigration on the economic development of sending countries. Specifically, our study is concerned with how feedback effects of brain drain may mitigate some of the loss incurred from the outflow of talent. We construct an endogenous growth model incorporating skilled emigration to consider in detail how the inflow of remittances, network externalities of t

We consider a technique involving Neural Networks in order to try to predict trends for cryptocurrencies such as Bitcoin, Ethereum etc. In that respect the project involves construction, design and training of a deep learning Neural Network based on historical trading data for these cryptocurrencies. Subsequently we apply this trained network in order to better understand its ability to possibly f

This thesis work aims to find a suitable environment for different virtualization system to achieve enhanced performance. Virtualization plays a vital role in cloud services, and it is essential to help cloud users comprehend the brief distinction between different virtualization technologies. The hypervisor-based technology has been used as the primary selection for cloud services in the past, bu

The increase in population and urbanization has led to widespread concern about the resulting volume of consumption. This is especially problematic in the housing market, where home size continues to grow. In the United States the average size of a single-family home has doubled since 1950, leading to a profound environmental impact. This paper will seek to address the problem of overconsumption b

The aim of this thesis is to give a statistical description of a neu- tron traversing a neutron detector system consisting of a polycrys- talline support material. The material used as support material in this project is aluminium although the results are applicable to any polycrystalline material. A mathematical description of the possible interactions in the detector system will be given, from w

Populärvetenskaplig sammanfattning Supramolekylär kemi är en relativt ny gren av kemin som involverar stora kemiska strukturer/enheter. Ett exempel på en ”supramolekyl” man dagligdags träffar på är klorofyll. Klorofyll (Figur 1 till vänster) består av en metall (magnesium) och en större kolvätestruktur som kallas porfyrin. Porfyriner finns i många olika varianter och används ofta i olika biologiskDuring the time range of this project, various compounds were synthesized. All of them will be used to synthesize the final compounds 2 and 3. Consequently, the compounds will build up a supramolecular cavity, which will be used to study a catalytic epoxidation of olefins. The aim of the project was furthermore to gain experience in laboratory work.

This report is the result of a Master Thesis project in Mechanical Engineering with Industrial Design at the Faculty of Engineering LTH at Lund University. The project was conducted in collaboration with ArjoHuntleigh AB, a company based in Malmö, Sweden. ArjoHuntleigh develops integrated healthcare solutions for people with low mobility and thereto related problems. The report describes the deve

Metallic hip prosthesis is an implant that gets more common and comes with problems like metallosis (inflammation due to metallic debris). Magnetic resonance imaging (MRI) which is a superior method when imaging soft tissue (compared to other medical imaging techniques) is affected by metal implants and will result in a distorted image.

Vulvar pain has been known of for thousands of years but the general knowledge of vulvar pain is limited and the condition receives less medical attention than other disorders. Previous research focus on physical and/or psychological causes, treatment strategies and problematizing female sexuality due to women’s inability to engage in sexual intercourse. This master thesis attempt to understand v

Utveckling och utredning av en automatiserad temperatur kalibrering temperatur fosfor. I denna avhandling presenteras en halvautomatisk temperaturkalibrering för termografiska fosforer. Temperaturdata från termoelement, och fosforensens avklingningskurva registreras och synkroniseras med en temperatur som ökar kontinuerligt över ett bestämt temperaturintervall. Ett LabVIEW-gränssnitt har utvecklaThis thesis achieves a semi-automatic temperature calibration for thermographic phosphors. Thermocouple temperature information and phosphorescence decay curves are recorded synchronized and continuously while the oven temperature is ramped across the entire temperature range. A LabVIEW interface was developed in this context and applied to calibrate two phosphors, CdWO4 and Mg4FGeO6:Mn. These two

Among the multidimensional effects that forced displacement has on population welfare, the economic ones may be measured in various ways: one of them is assessing the effect of being a forced migrant in the probability of accessing the labor market in the destination communities in Colombia. This is obtained through the estimation of a logit model which uses data from the “Survey in marginalized a

The introduction of the Environmental Transmission Electron Microscope (ETEM) has revolutionized scientific studies by allowing in-situ studies of nano and angstrom scale samples in varying environments. In combination with the introduction of the Microelectromechanical Systems (MEMS) chip the ETEM has become a powerful tool for high resolution imaging of material interaction. However, the MEMS ch
