  1. 1. Bandwidth Limited Distributed Optimization with Applications to Networked Cyberphysical Systems

    Author : Sindri Magnússon; Carlo Fischione; Steven Low; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Optimization; Resource Allocation; Power Networks; Limited Communication; Networks; Cyberphysical Systems; Wireless Sensor Networks; Internet of Things; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The emerging technology of Cyberphysical systems consists of networked computing, sensing, and actuator devices used to monitor, connect, and control physical phenomena. In order to economically and sustainably operate Cyberphysical systems, their devices need to cooperate over a communication network to solve optimization problems. READ MORE

  2. 2. Modeling and constructing unstructured overlay networks: Algorithms, techniques and the Smart Grid case

    Author : Georgios Georgiadis; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; matching; smart grid; online computation; scheduling; unstructured overlays; random walks; natural computing; resistor networks; clustering;

    Abstract : Throughout its lifetime, the Internet was always associated with overlay networks; from the WorldWideWeb and peer-to-peer networks to blogs and social networking solutions, overlays built on the Internet infrastructure gave it additional value and made it more engaging to everyday users. Today, rising overlay networks such as the Smart Grid as well as a multitude of sensor, mobile andwireless networks herald a new era of unprecedented connectivity and networking. READ MORE

  3. 3. Artificial neural networks : applications in morphometric and landscape features analysis

    Author : Amir Houshang Ehsani; Fredrich Quiel; Wolter Arnberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik;

    Abstract : In this thesis a semi-automatic method is developed to analyze morphometric features and landscape elements based on Self Organizing Map (SOM) as a unsupervised Artificial Neural Network algorithm. Analysis and parameterization of topography into simple and homogenous land elements (landform) can play an important role as basic information in planning processes and environmental modeling.
