1. 1. Deflationism : A Use-Theoretic Analysis of the Truth-Predicate

   Författare :Arvid Båve; Peter Pagin; Panu Raatikainen; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; truth; deflationism; disquotationalism; proposition; use-theory; semantics; nominalism; inferentialism; assertibility; that-clause; singular term; Tarski; Horwich; Field; meaning; Philosophy subjects; Filosofiämnen;

   Sammanfattning : I here develop a specific version of the deflationary theory of truth. I adopt a terminology on which deflationism holds that an exhaustive account of truth is given by the equivalence between truth-ascriptions and de-nominalised (or disquoted) sentences. LÄS MER

3. 2. Studies of some Operators of Harmonic Analysis in certain Function Spaces with Applications to PDEs

   Författare :Staffan Lundberg; Norway Narvik UiT The Arctic University of Norway Department of Computer Science and Computational Engineering Faculty of Science and Technology; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Operators; Hardy Operators; Potential Operators; Singular Operators; Function Spaces; Morrey Spaces; H¨older Spaces; Partial Differential Equations; Inequalities; Hardy Type Inequalities; Weights; Applications; Matematik; Mathematics;

   Sammanfattning : The study in this PhD thesis aims at development of certain mathematical methods used in applications, in particular, in the study of regularity properties of solutions in various mathematical models described by Partial Differential Equations (PDEs). To this end, we study various operators of harmonic analysis in certain function spaces, since solutions to many PDEs may be expressed in terms of such operators. LÄS MER

4. 3. Regulation of G2 phase and long-term consequences of DNA damage

   Författare :Anna Won Middleton; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Cell proliferation requires the accurate replication of DNA and equal segregation of replicated genes, important for maintaining the integrity of newly formed cells. At the centre of this process is a series of coordinated events termed ‘the cell cycle’, which ensures cell proliferation proceeds with high fidelity. LÄS MER

5. 4. Large Scale Solar Power Integration in Distribution Grids : PV Modelling, Voltage Support and Aggregation Studies

   Författare :Afshin Samadi; Lennart Söder; Olof Samuelsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic systems; PV system modelling; reactive power control; droop control; voltage sensitivity analysis; German Grid Codes; relative gain array RGA ; singular value decomposition SVD ; load modeling; system identification; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. LÄS MER

7. 5. On Monte Carlo Operators for Studying Collisional Relaxation in Toroidal Plasmas

   Författare :Qaisar Mukhtar; Torbjörn Hellsten; Tainia Kurki-Suonio; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fusion plasma; thermonuclear fusion; tokamak; Coulomb collisions; stochastic differential equations with singular diffusion coefficients; Monte Carlo schemes; spatial diffusion; modelling; Fokker-Planck equation; RF-heating.;

   Sammanfattning : This thesis concerns modelling of Coulomb collisions in toroidal plasma with Monte Carlo operators, which is important for many applications such as heating, current drive and collisional transport in fusion plasmas. Collisions relax the distribution functions towards local isotropic ones and transfer power to the background species when they are perturbed e. LÄS MER
