1. 1. Secure GNSS-based Positioning and Timing : Distance-Decreasing attacks, fault detection and exclusion, and attack detection with the help of opportunistic signals

   Författare :Kewei Zhang; Panagiotis Papadimitratos; Erik G. Larsson; Christina Pöpper; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : With trillions of devices connected in large scale systems in a wired or wireless manner, positioning and synchronization become vital. Global Navigation Satellite System (GNSS) is the first choice to provide global coverage for positioning and synchronization services. LÄS MER

3. 2. On Robust Steering Based Lateral Control of Longer and Heavier Commercial Vehicles

   Författare :Maliheh Sadeghi Kati; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rearward Amplification; static output feedback; Commercial vehicles; LMI-based H ∞ synthesis; Dynamic Feed-forward; Robust Control;

   Sammanfattning : Rapid growth in the transportation of goods has led to raised concerns about environmental effects, road freight traffic, and increased infrastructure usage. The increasing cost of fuel, and issues with congestions and gas emissions, make longer and heavier commercial vehicles (LHCVs) an attractive alter- native to conventional heavy vehicles. LÄS MER

4. 3. Affordable identification and modelling of uncertain design specifications when introducing new technologies in space applications

   Författare :Olivia Borgue; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engineering specifications; Technology introduction; uncertainties identification.; space components; model-based systems engineering;

   Sammanfattning : When introducing new technologies in space products, both the uncertainties regarding technology feasibility and the way in which the technology affects the product development process hinder the early establishment of appropriate engineering specifications. Failing to establish product specifications during conceptual stages leads to problems discovered during later phases of the product development process, when design and process changes are the most expensive.

5. 4. On Cooperative Control of Automated Driving Systems from a Stability and Safety Perspective

   Författare :Roozbeh Kianfar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reachability Analysis; Intelligent Transportation; Platooning; String Stability; Distributed Control;

   Sammanfattning : Over the last few decades, congested traffic network have become a seriousproblem in many countries. Congestions result in time losses, increase of fuelconsumption and also raise the risk of accidents. Intelligent transportationsystems may contribute to mitigate such problems. LÄS MER

7. 5. Towards a Concurrent Multidisciplinary Design Optimization of Mechatronic Systems

   Författare :Fariba Rahimi; Martin Grimheden; Johan Ölvander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

   Sammanfattning : Multidisciplinary design optimization of mechatronic systems is a cumbersome task that considers integration of several engineering domains simultaneously. Hence, a holistic method should treat these engineering domains concurrently in the development phase and result in a solution for the system that is optimum considering several disciplines. LÄS MER
