  2. 1. Distributed Stochastic Programming with Applications to Large-Scale Hydropower Operations

    Author : Martin Biel; Mikael Johansson; Lennart Söder; David Woodruff; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stochastic programming; distributed; algorithms; large-scale; optimization; hydropower; software; julia language; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Stochastic programming is a subfield of mathematical programming concerned with optimization problems subjected to uncertainty. Many engineering problems with random elements can be accurately modeled as a stochastic program. In particular, decision problems associated with hydropower operations motivate the application of stochastic programming. READ MORE

  4. 2. Large-Scale Production and Use of Biomethane

    Author : Alberto Alamia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dual fuel; Biomass gasification; SNG; power-to-gas; well-to-wheel; biomethane; biorefinery; GoBiGas; DFB gasifier; process simulation;

    Abstract : Societal ambitions to create an economy based on renewable resources, require the development of technologies transforming these resources into energy-carrying products and biomaterials. Dual fluidized bed (DFB) gasification represents a key technology for achieving sustainability targets, as it is a scalable and highly efficient route for the conversion of biomass. READ MORE

  5. 3. Large-scale agile transformation in a manufacturing company : a knowledge-based view

    Author : Silvia Orejuela; Innovation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large-scale agile; Organisational transformation; Knowledge specialisation; Knowledge boundaries; Knowledge integration; Manufacturing company;

    Abstract : Agile has been touted as a concept to deal with and succeed in the fast-paced environment in which companies operate today. Based on this concept, practitioners have created frameworks and practices that have proven to bring benefits in software development. READ MORE

  6. 4. Large-Scale Graphene Production for Environmentally Friendly and Low-Cost Energy Storage : Production, Coating, and Applications

    Author : Nicklas Blomquist; Håkan Olin; Renyun Zhang; Christina Dahlström; Patrik Johansson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Energy storage; Supercapacitors; EDLC;

    Abstract : There is great demand for energy-efficient, environmentally sustainable, and cost-effective electrical energy storage devices. One important aspect of this demand is the need for automotive electrification to achieve more energy-efficient transportation at a reasonable cost, thus supporting a fossil-fuel free society.
