1. On the Adaptive Array Problem
Sammanfattning : By an array we mean a set of coupled sensors, typically antenna elements. The array receives superimposed signals from distant sources. By combining the outputs of the sensors in different ways, one can change the array sensitivity to different Directions-of-Arrival (DOA). LÄS MER
2. Funnel-Based Control for Coupled Spatiotemporal Specifications
Sammanfattning : In the past decade, the integration of spatiotemporal constraints into control systems has emerged as a crucial necessity, driven by the demand for enhanced performance, guaranteed safety, and the execution of complex tasks. Spatiotemporal constraints involve criteria that are dependent on both space and time, which can be represented by time-varying constraints in nonlinear control systems. LÄS MER
3. Tools for Structured Matrix Computations : Stratifications and Coupled Sylvester Equations
Sammanfattning : Developing theory, algorithms, and software tools for analyzing matrix pencils whose matrices have various structures are contemporary research problems. Such matrices are often coming from discretizations of systems of differential-algebraic equations. LÄS MER
4. Finite Element Modelling of Fluid-Structure Interaction
Sammanfattning : The dynamic interaction between non-viscid, compressible fluid and an elastic structure is studied. Finte element formulations, using the weighted residual method, are derived. Different primary variables in the fluid domain are used and different source functions are considered. LÄS MER
5. Finite-Length Scaling Laws for Spatially-Coupled LDPC Codes
Sammanfattning : This thesis concerns predicting the finite-length error-correcting performance of spatially-coupled low-density parity-check (SC-LDPC) code ensembles over the binary erasure channel. SC-LDPC codes are a very powerful class of codes; their use in practical communication systems, however, requires the system designer to specify a considerable number of code and decoder parameters, all of which affect both the code’s error-correcting capability and the system’s memory, energy, and latency requirements.
