2. 1. Robot Path Planning

   Author : Robert Bohlin; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis consists of three papers concerned with the basic path planning problem for robots moving in a known static environment. Our main interest has been industrial robots, but the methods are general and apply to a wide range of robots. READ MORE

4. 2. Survival of the Unfit : Path Dependence and the Estonian Oil Shale Industry

   Author : Rurik Holmberg; Staffan Laestadius; Mats Bladh; Mats Söderström; Nick von Tunzelmann; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Estonia; oil shale; path dependence; lock-in; institutions; knowledge; Sweden; innovation; Soviet Union; technology; systems; energy; shale oil; electricity; fossil fuel; environment; economy; Technology and social change; Teknik och social förändring;

   Abstract : Estonia is the only country in the world, which is totally dependent on oil shale in its energy system. Although this fossil fuel exists in enormous quantities around the world, it has so far not been utilized on a larger scale. The reasons for this have been both economic and, in recent times, ecological. READ MORE

5. 3. Aspects of Wide-Area Damping Control Design using Dominant Path Synchrophasor Signals

   Author : Yuwa Chompoobutrgool; Luigi Vanfretti; Glauco Nery Taranto; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power system stability and control; inter-area oscillations; wide-area damping control; synchrophasor measurements; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The presence of inter-area oscillations has long affected stability constraints, and therefore, limited the power transfer capacity of interconnected power systems. Adequate damping of these inter-area oscillations is, thus, necessary to secure system operation and ensure system reliability while increasing power transfers. READ MORE

6. 4. Modeling and optimization of least-cost corridors

   Author : Lindsi Seegmiller; Takeshi Shirabe; Kai-Florian Richter; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; raster data modeling; raster-based geographic information systems; route planning; optimal routing; corridor; wide path; corridor width; distortion; three-dimensional grid; rasterdatamodellering; rasterbaserade geografiska informationssystem; ruttplanering; optimal dirigering; korridor; bred väg; korridorbredd; distorsion; tredimensionellt rutnät; Geoinformatics; Geoinformatik;

   Abstract : Given a grid of cells, each having a value indicating its cost per unit area, a variant of the least-cost path problem is to find a corridor of a specified width connecting two termini such that its cost-weighted area is minimized. A computationally efficient method exists for finding such corridors, but as is the case with conventional raster-based least-cost paths, their incremental orientations are limited to a fixed number of (typically eight orthogonal and diagonal) directions, and therefore, regardless of the grid resolution, they tend to deviate from those conceivable on the Euclidean plane.

7. 5. Post Impact Vehicle Path Control in Multiple Event Accidents

   Author : Derong Yang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident Analysis; Multiple-Event Accidents; Post Impact; Collision Avoidance; Optimal Path Control.; Vehicle Dynamics;

   Abstract : Recent statistics show that multiple-event accidents (MEAs) possess an increasing fraction of all vehicle traffic accidents. They are characterized by having at least one vehicle subjected to more than one harmful event, such as collision with another vehicle. MEAs now comprise approximately 25% of all passenger vehicle accidents. READ MORE
