During this thesis work, a frequency stabilization system for an External Littrow Cavity Diode Laser (ECDL) at 370 nm has been set up and tested. The goal of the frequency stabilization is to achieve a long term frequency stability of less than ±50 kHz within 8 hours, which will be used for the single Ce ion detection project in the quantum information group. The system design is centered around a

Sepsis is a serious clinical syndrome and one of the most common causes of death. It is defined as a microbial invasion and excessive immune reaction. There is no common cure for sepsis, and mortality in sepsis is high and rises quickly, so it is important to start precise treatment quickly. Sepsis is, however, hard to diagnose, as it has no symptoms specific to it alone, and thus new ways to diag

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.

I Sverige är diabetes typ 1 en av de vanligaste kroniska sjukdomarna hos barn. Den största incidensökning finns bland barn yngre än fem år. Övergripande mål för diabetesbehandling är en god metabol kontroll med egenvårdskunskaper som föräldrarna och barnen får i samband med insjuknandet. Syftet med studien var att undersöka föräldrarnas tillfredställelse med vården 6 månader efter att deras barn d

Abstract Type 1 Diabetes is an autoimmune disease characterized by chronic hyperglycemia that results from a selective loss of insulin secreting pancreatic beta cells. The aetiology of T1D often involves both genetic and environmental factors like viral infections. In T1D, insulin is regarded as primary autoantigen that becomes one of the targets of autoimmune attack and is found to be expressed i

The aim of our study was: to analyze how the phenomena “curlingföräldrar” (curling parents) is produced in the television program "Ung och bortskämd" (Young and spoiled), and more generally to interpret this social phenomenon from the media's point of view. The study was based on the following questions: How are curling parents portrayed in the tv-show "Ung och bortskämd",

A big challenge in the Wind Power industry is the breakdown of gearboxes. To increase the knowledge about Wind Power and gearbox breakdowns Vattenfall has done measurements on both the mechanical and electrical system of a wind power turbine e.g. during full load and partial load. In this Master Thesis focus is on voltage and current measurements on the generator conductors and the measurements of

Power quality is an important issue for the distribution network companies. They must guarantee the electricity supply fulfilling the requirements for the consumers. In this thesis we investigate specifically voltage requirements. We use transformers and tap changers to see how the voltage works in an electric system and we analyze the relationships with other aspects of the system’s performance,

In today's industry the need for fast logging of measurements is increasing. Existing systems used by Tetra Pak AB have a maximum logging frequency which is inadequate. As a result of this Tetra Pak gave Industriprojektbyrån AB the task of developing a measuring system for this purpose. Industriprojektbyrån AB has before the start of this thesis developed the hardware set up for the system. Th
