1. 1. Sequential complex FIR-structure optimization

   Författare :To Tran; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Impulse Response FIR ; Digital filter design;

   Sammanfattning : Over the past 40 years, the area of digital signal processing and filtering has undergone a rapid development. Today, most of the filtering tasks, that before were performed by using analog technology, have been substituted with inexpensive and, often, more reliable and flexible digital solutions. LÄS MER

3. 2. Utilizing Problem Structure in Optimization of Radiation Therapy

   Författare :Fredrik Carlsson; Anders Forsgren; Edwin Romeijn; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; intensity-modulated radiation therapy; conjugate-gradient method; step-and-shoot delivery; column generation; quasi-Newton method; regularization; sequential quadratic programming; Optimization; systems theory; Optimeringslära; systemteori;

   Sammanfattning : In this thesis, optimization approaches for intensity-modulated radiation therapy are developed and evaluated with focus on numerical efficiency and treatment delivery aspects. The first two papers deal with strategies for solving fluence map optimization problems efficiently while avoiding solutions with jagged fluence profiles. LÄS MER

4. 3. Structure-Exploiting Numerical Algorithms for Optimal Control

   Författare :Isak Nielsen; Daniel Axehill; Anders Hansson; Eric Kerrigan; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical Optimal Control; Model Predictive Control; Riccati Recursion; Parallel Algorithms; Low-Rank Modifications; Parametric Programming; Optimization; Explicit MPC; Moving Horizon Estimation; Partial Condensing;

   Sammanfattning : Numerical algorithms for efficiently solving optimal control problems are important for commonly used advanced control strategies, such as model predictive control (MPC), but can also be useful for advanced estimation techniques, such as moving horizon estimation (MHE). In MPC, the control input is computed by solving a constrained finite-time optimal control (CFTOC) problem on-line, and in MHE the estimated states are obtained by solving an optimization problem that often can be formulated as a CFTOC problem.

5. 4. Computationally efficient exact remodeling of optimization programs with applications to autonomous driving

   Författare :Johan Karlsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous driving; Real-time implementation; Model predictive control; Convex optimization;

   Sammanfattning : The future of autonomous vehicles is rapidly approaching and the published and available research, both from vehicle manufacturers and universities, is abundant. This new technology promises less pollution, lower accident rates, decreased congestion and the possibility to relax or work while a vehicle takes you where you need to go. LÄS MER

7. 5. Optimization-based coordination strategies for connected and autonomous vehicles

   Författare :Robert Hult; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Optimization; Optimal Control; Connected Automated Vehicles; Intersection Coordination;

   Sammanfattning : Automated vehicles (AV) are expected to reach the consumer market within the next decade. Once AVs become ubiquitous, they could resolve difficult traffic situations through communication-based cooperation. LÄS MER
