   Författare :David A. Anisi; Xiaoming Hu; Randal Beard; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surveillance Missions; Minimum-Time Surveillance; Unmanned Ground Vehicles; Connectivity Constraints; Combinatorial Optimization; Computational Optimal Control; Receding Horizon Control; Mission Uncertainty; Safety; Task Completion; Adaptive Grid Methods; Missile Guidance; Nonlinear Observer Design; Active Observers; Non--uniformly Observable Systems; Mobile Robotic Systems; Intrinsic Observers; Differential Geometric Methods; Euler-Lagrange Systems; Contraction Analysis.; Optimization; systems theory; Optimeringslära; systemteori; Applied mathematics; Tillämpad matematik;

   Sammanfattning : The main body of this thesis consists of six appended papers. In the  first two, different  cooperative surveillance problems are considered. The second two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. LÄS MER

3. 22. On Optimal Integrated Task and Motion Planning with Applications to Tractor-Trailers

   Författare :Anja Hellander; Daniel Axehill; Martin Enqvist; Kristoffer Bergman; Yiannis Karayiannidis; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : An important aspect in autonomous systems is the ability of a system to plan before acting. This includes both high-level task planning to determine what sequence of actions to take in order for the system to reach a goal state, as well as low-level motion planning to detail how to perform the actions required.

4. 23. Data-driven models for railway track geometry maintenance

   Författare :Hamid Khajehei; Alireza Ahmadi; John Andrews; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data-driven models; degradation; maintenance; tamping; track geometry; planning and scheduling; railway infrastructure; Drift och underhållsteknik; Operation and Maintenance;

   Sammanfattning : Railways are currently experiencing higher demands on safety, infrastructure performance, network capacity and service quality, etc. As a result, a high level of track availability, service quality and infrastructure robustness against unexpected events is required, at reduced cost, to meet the demands.

5. 24. Health care financing in China : equity in transition

   Författare :Lennart Bogg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Equity; gender; health expenditure; health financing; health insurance; health reform; health services; family planning; maternal health; tuberculosis; China;

   Sammanfattning : The aim of the thesis is 1) to assess equity in the provision, financing and utilization of health services in the study counties, after the launching of the Chinese health reform, in relation to income and health status, 2) to assess equity in utilization, financial barriers to care and poverty impact and the association of financial variables; alternative health insurance systerns and out-of-pocket financing and the association of non-financial variables; gender, age, education, occupation and geographical distance to health facilities. The data collection was carried out from 1993 to 1996. LÄS MER

7. 25. Simulation and execution of autonomous robot systems

   Författare :Magnus Olsson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Elektronik och elektroteknik; sensor simulation robotics; Electronics and Electrical technology; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : Traditional off-line programming is not enough in order to use the full potential of virtual models and simulation system in industrial robot applications. The interface between off-line programming system and the robot controller is today restricted to program transfer. LÄS MER
