3. 2. Energy Saving vs. Performance: Trade-offs in Optical Networks

   Författare :Pawel Wiatr; Paolo Monti; Josep Solé-Pareta; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-efficiency; optical networks; RWA; side-effects; device reliability performance; network performance; operational cost; benefits; loss; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The energy consumption of communication networks is continuously growing. Many energy saving approaches have been proposed at the device, system, and network level. The most promising way to address this problem is to utilize photonic technologies as much as possible thanks to their low energy consumption per bit performance. LÄS MER

4. 3. Cost-effective Communication and Control Architectures for Active Low Voltage Grids

   Författare :Mikel Armendáriz; Lars Nordström; Sami Repo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active low voltage distribution grids; CAPEX OPEX; communication control architectures; cost-effectiveness; MPC; multiagent systems; photovoltaics; voltage control.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The monitoring and control of low voltage distribution grids has historically been disregarded due to the unidirectional flow of power. However, nowadays the massive integration of distributed energy resources into distribution grids, such as solar photovoltaics, distributed storage, electric vehicles and demand response programs, presents some challenges.

5. 4. Cooperative Transportation Planning and Cost Allocation

   Författare :Joen Dahlberg; Maud Göthe-Lundgren; Stefan Engevall; Jenny Karlsson; Endre Bjørndal; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : A freight forwarder may consolidate its goods transportations in order to achieve a more efficient operation. When goods transportations are consolidated, they may reduce operational costs, e.g. labor and fuel. LÄS MER

7. 5. Total Cost Indicators - Operational Performance Indicators for managing environmental and economic efficiency

   Författare :Thomas Parker; Internationella miljöinstitutet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Environmental management indicators accounting assessment;

   Sammanfattning : In this Licentiate Dissertation presents a new model for selecting environmental performance indicators in order to improve environmental management. The suggested Total Cost Indicators support a support a preventive approach to environmental management, where environmental issues are addressed before they arise - and before they become costs.
