1. 1. Low Cycle Fatigue and Thermo-Mechanical Fatigue of Uncoated and Coated Nickel-Base Superalloys

   Författare :Svjetlana Stekovic; Torsten Ericsson; Hael Mughrabi; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AMDRY997; CMSX-4; SCB; Thermo-Mechanical Fatigue; Coatings; Gas Turbine; IC1; IC3; IN792; Low Cycle Fatigue; Nickel-Base Superalloys; RT22; Materials science; Teknisk materialvetenskap;

   Sammanfattning : High strength nickel-base superalloys have been used in turbine blades for many years because of their superior performance at high temperatures. In such environments superalloys have limited oxidation and corrosion resistance and to solve this problem, protective coatings are deposited on the surface. LÄS MER

   Sammanfattning : This dissertation explores the early digitalization in Sweden. As host to the first summit on the environment in Stockholm 1972 (UNCHE), as leading procurer of computer equipment as well as initiator to the world's first national Data Act of 1973, Sweden pioneered domains that have since emerged as critical to our age: environmental challenges and digital technology.

4. 3. Fast-tunable resonators and quantum electrical circuits

   Författare :Martin Sandberg; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SEB; tunable; Sisyphus resistance; CPW; Resonator; SCB; qubit; circuit-QED; transmon; SQUID;

   Sammanfattning : In this thesis, measurements on superconducting electrical circuits that exhibit quantum mechanical effects are presented. Nonlinear superconducting circuits can be regarded as artificial atoms with energy spectra that can be engineered. The artificial atoms can be used as quantum bits for quantum computation. LÄS MER

5. 4. Tunable superconducting transmissionline resonator for qubit coupling

   Författare :Martin Sandberg; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fast tuning; superconductivity; transmission line; SCB; Josephson inductance.; Frequency tunable resonator; SQUID; CPW; aluminium;

   Sammanfattning : In this licentiate thesis design, fabrication, and measurements of tunable superconducting microwave transmission line resonators are described. The resonators are of quarter wavelength type were the tuning is achieved by changing one of the boundary conditions of the resonator through a tunable impedance. LÄS MER

7. 5. The Single Cooper Pair Box - a Quantum-Mechanical Electronic Circuit

   Författare :David Gunnarsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum capacitance; quantum computing; single Cooper-pair box; SET; radio-frequency single-electron-transistor; macroscopic quantum coherence; Qubit;

   Sammanfattning : In this thesis the single Cooper pair box (SCB) is investigated with a radio frequency single electron transistor (RF-SET). The RF-SET is used as an electrometer to detect the charge of the SCB. The SCB can be regarded as a quantum two-level system and could therefore be a possible qubit. LÄS MER
