1. 11. Distributed Control of Electric Drive Systems via Ethernet

   Författare :Lilantha Samaranayake; Chandur Sadarangani; Alexander Medvedev; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptive sampling scheme; control delay; delay compensation; distributed control systems; Ethernet; Ethernet ready sensor actuator module; sampling period; Electrical engineering; Elektroteknik;

   Sammanfattning : This thesis is on adapting standard Switched Ethernet for distributed control applications in electric drive systems. The critical issue of Ethernet here is to provide services to real-time applications. LÄS MER

3. 12. Dynamics in magnetic metamaterials

   Författare :Agnė Čiučiulkaitė; Vassilios Kapaklis; Gabriella Andersson; Björgvin Hjörvarsson; Will Branford; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Metamaterials are artificially created structures with properties that are not found in nature. They can be tailored to achieve desired response to external excitations such as external electric and magnetic fields, as well as to enhance materials’ optical or magnetic activity. LÄS MER

4. 13. NMR STUDIES ON STRUCTURE AND DYNAMICS OF TWO-DOMAIN PROTEINS

   Författare :Houman Ghasriani; Biofysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Biochemistry; Metabolism; Biokemi; metabolism; Physical chemistry; Molekylär biofysik; CRISP-3; NMR; 3D-structure; NMR relaxation; Molecular biophysics; Prostate cancer; EGF module; PSP94; Beta-microseminoprotein; Protein S;

   Sammanfattning : The general objective of the present thesis work was to examine 3-dimensional structure as well as the motional properties of two different types of two-domain proteins by solution-state NMR. One of the major tasks of this thesis work was to investigate the domain orientation of these molecules by employing residual dipolar couplings (RDC) which can be used as orientational restraints for increasing the accuracy of protein structures determined by NMR.

5. 14. Structure formation, phase transitions and drag interactions in multicomponent superconductors and superfluids

   Författare :Karl Sellin; Egor Babaev; Anatoly Kuklov; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

   Sammanfattning : Superconductivity and superfluidity are some of the most funda-mental and important phenomena of modern physics. However, muchtheoretical work for such systems so far has been restricted to the one-component case. LÄS MER

7. 15. The Testatin/Cres subgroup of family 2 cystatins in sexual development

   Författare :Jessica Frygelius; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The genetic sex in mammals is established at fertilization, where an XX chromosome complement will lead to female development and an XY genotype will result in male development. Thereafter, sex determination is initiated with expression of the Y-linked factor Sry in XY gonads, leading to testis formation, while in the absence of Sry expression an ovary is formed. LÄS MER
