1. 1. Dynamics of Vortices and Charges in Two Dimensional Arrays of Small Josephson Junctions

   Författare :ChiiDong Chen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis is based on experimental work on two dimensional (2D) Josephson junction arrays. The junctions are small (~ 0.004~0.04 µm2) so that the charging energy E~ e2/2C associated with the junction capacitance C is large. LÄS MER

3. 2. Transformation and Symbolic Calculations in Filtering and Control

   Författare :Ke Wang-Chen; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis deals with several aspects of optimal control and filtering problems. A fundamental problem in the optimal control theory is the design of a regulatorfora linear system which minimizes a quadratic cost function characterizing the control effort and the deviations of the system from the ideal operation.
