  1. 1. Control Lyapunov Functions : A Control Strategy for Damping of Power Oscillations in Large Power Systems

    Författare :Mehrdad Ghandhari; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UPFC; CSC; QBT; Lyapunov function; Control Lyapunov Function; SIME; Sliding mode; Electric power engineering; Elkraftteknik;

    Sammanfattning : In the present climate of deregulation and privatisation, theutilities are often separated into generation, transmission anddistribution companies so as to help promote economic efficiencyand encourage competition. Also, environmental concerns,right-of-way and cost problems have delayed the construction ofboth generation facilities and new transmission lines while thedemand for electric power has continued to grow, which must bemet by increased loading of available lines.

  3. 2. Robot Task Learning from Human Demonstration

    Författare :Staffan Ekvall; Danica Kragic; Marcus Vincze; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robotics; Machine Learning; Artificial Intelligence; Computer Vision; Programming by Demonstration; Grasp Mappping; Grasp Recognition; Robot Grasping; Planning; Autonomous Robots; Computer science; Datalogi;

    Sammanfattning : Today, most robots used in the industry are preprogrammed and require a welldefined and controlled environment. Reprogramming such robots is often a costly process requiring an expert. By enabling robots to learn tasks from human demonstration, robot installation and task reprogramming are simplified. LÄS MER

  4. 3. Boundary and Interface Conditions for Electromagnetic Wave Propagation using FDTD

    Författare :Jon Häggblad; Björn Engquist; Olof Runborg; Thomas Rylander; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Numerisk analys;

    Sammanfattning : Simulating electromagnetic waves is of increasing importance, for example, due to the rapidly growing demand of wireless communication in the fields of antenna design, photonics and electromagnetic compatibility (EMC). Many numerical and asymptotic techniques have been developed and one of the most common is the Finite-Difference Time-Domain (FDTD) method, also known as the Yee scheme. LÄS MER

  5. 4. Higher education meets private use of social media technologies : An explorative study of students’ use

    Författare :Pernilla Josefsson; Stefan Hrastinski; Olle Bälter; Daniel Pargman; Grainne Conole; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Social Media; Social Media Technologies; Higher Education; Media Technology; Digital Media; Computer Science; Datalogi;

    Sammanfattning : The work in this thesis sets out to explore how students perceive social media use in the context of higher education. More precisely, the focus is on students' use of, experience with, and attitudes toward the integration of social media into their learning environment. LÄS MER

  7. 5. Dynamics and Thermodynamics of Translational and Rotational Diffusion Processes Driven out of Equilibrium

    Författare :Raffaele Marino; Erik Aurell; Lacoste David; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Translational and Rotational Diffusion Processes; Brownian; Fysik; Physics;

    Sammanfattning : Diffusion processes play an important role in describing systems in many fields of science, as in physics, biology, finance and social science. One of the most famous examples of the diffusion process is the Brownian motion. LÄS MER
