1. 6. Clinical application of QLF and DIAGNOdent : two new methods for quantification of dental caries

   Författare :Sofia Tranæus; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : General aim: The general objective of this thesis was to evaluate the clinical performance of two new methods for quantification of dental caries - the Quantitative Light-induced Fluorescence method (QLF) and KaVo DIAGNOdent. Materials and methods: In Paper I, in vivo measurements with QLF on teeth scheduled for extraction, were compared with transverse microradiography (TMR), and tested for intra-operator reliability.

3. 7. Spin Transport Studies of Nanoscaled Ferromagnetic Tunneling Devices

   Författare :Ruisheng Liu; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tunneling anisotropic magnetoresistance.; tunneling magnetoresistance; ferromagnetic single electron transistor; spin relaxation; Spin transport;

   Sammanfattning : This thesis presents spin transport studies of ferromagnetic nano-scaled tunneling devices fabricated by atomic force microscopy (AFM) and electron beam lithography (EBL). The thesis covers three main topics: The first topic is a study of spin accumulation (relaxation) in Au nano-structures using Ni/Au/Ni ferromagnetic single electron transistors (F-SETs). LÄS MER

4. 8. Fabrication and Characterization of magnetometer for space applications

   Författare :Fatjon Qejvanaj; Johan Åkerman; BRAD ENGEL; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AMR; Magnetic sensor; Ferromagnetic; Antiferromagnetic; NiFe; IrMn; exchange bias.; Fysik; Physics; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : The present rapid increase in the number of space missions demands a decrease in the cost of satellite equipment, but also requires the development of instruments that have low power consumption, low weight, and small size.Anisotropic magnetoresistance (AMR) sensors can answer these needs on account of their small size, weight, and power consumption.

5. 9. Development of the read-out link and control board for the ATLAS Tile Calorimeter Upgrade

   Författare :Eduardo Valdés Santurio; Samuel Bryant Silverstein; Costas Foudas; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HL-LHC; ATLAS; Tile Calorimeter; TileCal; Demonstrator; Daughterboard; Read-out; Digital electronics; Data acquisition; Radiation tolerant; GBTx; TID; NIEL; SEU; SEL; FPGA; Kintex 7; Ultrascale; Ultrascale ; Optic Links; fysik; Physics;

   Sammanfattning : The Phase-II upgrade plan for the ATLAS Hadronic Tile Calorimeter facing the High-Luminosity LHC (HL-LHC) era includes approximately 1000 radiation tolerant read-out link and control boards (Daughterboards) that will provide full-granularity digital data to a fully-digital trigger system off-detector through multi-Gbps optic fibres. Different Daughterboard (DB) revisions have been developed, each successively aiming to meet the demanding HL-LHC requirements. LÄS MER

7. 10. New Strategies for Ensuring Time and Value Correctness in Dependable Real-Time Systems

   Författare :Hüseyin Aysan; Sasikumar Punnekkat; Iain Bate; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Computer Science; datavetenskap;

   Sammanfattning : Dependable real-time embedded systems are typically composed of a number of heterogeneous computing nodes, heterogeneous networks that connect them and tasks with multiple criticality levels allocated to the nodes. The heterogeneous nature of the hardware, results in a varying vulnerability to different types of hardware failures. LÄS MER
