1. 1. Public Domain Intelligence Tests: Psychometric properties of the Cog15 and ICAR16 cognitive ability scales

   Master-uppsats, Lunds universitet/Institutionen för psykologi

   Författare :Dagný Kristjánsdóttir; Aya Zaiter; [2023]
   Nyckelord :general intelligence; intelligence testing; public domain; CFA; PCA; Social Sciences;

   Sammanfattning : The current paper aims to explore the psychometric properties of two public domain cognitive ability scales, Cog15 and ICAR16, and investigate how well they each capture the g-factor in a Swedish sample (N = 428). The motivation for choosing these aims is that public domain, free, and easily accessible intelligence tests are needed for measuring the g-factor. LÄS MER

3. 2. The Ratio of Reality : A study of the gyromagnetic ratio in theories ranging from classical mechanics to string theory

   Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Daniel Nilsson; [2021]
   Nyckelord : Quantum field theory ; String theory ; Dirac equation ; Dirac theory ; Dirac; gyromagnetic; ratio; g-factor; Kvantfältsteori; strängteori; Dirac; g-factor; gyrmagnetisk kvot ;

   Sammanfattning : In this project a theoretical study of the so called gyromagnetic ratio was done by investigating classical mechanics, Dirac theory and string theory. The gyromagnetic ratio is a constant term appearing in the coupling between angular momentum and magnetic moment for a particle. LÄS MER

4. 3. Electronic states in semiconductor double quantum dots and quantum rings - Theory and tight-binding modeling

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Författare :Calle Stenberg; [2021]
   Nyckelord :double quantum dots quantum rings tight-binding aharonov-bohm g-factor enhancement InAs; Physics and Astronomy;

   Sammanfattning : In recent experiments on semiconductor nanowires and quantum dots, enhanced g-factors up to several times the bulk value have been measured [1] [2]. The enhancement is attributed to orbital contributions g∗orb to the effective g-factor g∗ = g∗spin+g∗orb from the coupling of the high angular momentum ring-like states to the magnetic field.

5. 4. Characterization of InAs-Al semiconductor-superconductor hybrid devices

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Författare :Markus Aspegren; [2020]
   Nyckelord :quantum dot; superconductivity; quantum transport; josephson junction; spectroscopy; yu-shiba-rusinov; hybrid devices; sub-gap states; quantum computer; majorana bound state; bogoliubov quasiparticle; Physics and Astronomy;

   Sammanfattning : In this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. LÄS MER

7. 5. Is there a g factor in acedmic creative performance? : Evidence from bibliographical indices of Swedish academics

   Kandidat-uppsats, Umeå universitet/Institutionen för psykologi

   Författare :Pontus Fahlman; [2016]
   Nyckelord :;

   Sammanfattning : People's cognitive abilities are characterized by a general factor of intelligence, initially intuitedby Charles Spearman's (1904) observation that school children tend to have overall high oroverall low marks in many school subjects, rather than low in some and high in some. In the realmof real-world creative performance, it is similarly argued that people who produce more alsoproduce with higher quality, in other words a positive quantity-quality manifold rather than aquantity-quality tradeoff.
