Abstract:

The recent interest in developing highly controllable quantum bits (qubits) based on superconducting circuits makes it necessary to get a deeper understanding of the physics of small Josephson junctions. Such devices have to be wisely engineered and well isolated from the noisy environment to observe non-classical physics. In this thesis, a real-time noise analysis was implemented by an autocorrelation calculation to identify the type of environmental effects affecting a superconducting circuit. This was used during switching current measurements of small Josephson junctions to track the effec

Earlier research has studied if teacher acquires further education in there topics, not if knowledge about new technology can contribute to a better education. If teachers have good knowledge about new technology and forwarding it to the pupils, can it increase the interest for physics among the pupils? Didactic research has shown that pupils would like to see conjunction with the knowledge they receives and their natural world.

Abstract:

The front-loading washing machine is an integral part of household life for many, with little notice given to the extensive interplay of physical, chemical and thermal phenomena taking place as the clothes inside tumble. With over 250 billion washes carried out annually in Europe alone, it has a staggering environmental impact due to its energy and water usage and also due to the chemicals that are drained to the sewage system at the end of a wash. There are two practical routes for reducing this impact; improving the design of the machine so that it requires less energy or water, or improving

Historically, NDE methods for CFRPs have concentrated on through thickness measurements of ultrasonic attenuation or velocity to determine the presence of defects.

Abstract:

A technological platform based on low-temperature hybrid sol-gel method for fabrication of optical waveguides and integrated optical components has been developed. The developed chemistry for doping incorporation in the host network provides a range of refractive indexes (1.444-1.51) critical for device optimization. A passivation method for improving long-term stability of organic-inorganic sol-gel material is reported. The degradation of waveguide loss over time due to moisture adsorption from the atmosphere is drastically suppressed by coating the material with a protective thin SiO2 film.
