1. 16. 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

   Sammanfattning : This thesis analyzes the integration of electricity and transportation systems for a future in which transportation is increasingly electrified. The focus is on exploring the infrastructures required for the indirect electrification of heavy transportation and the direct electrification of passenger vehicles. LÄS MER

5. 19. An assessment of operational consequences of failures to support aircraft scheduled maintenance program development

   Författare :Alireza Ahmadi; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Sammanfattning : A majority of the direct and indirect maintenance costs in the life cycle of aircraft stems from the consequences of decisions taken during the initial maintenance program development. In particular, the preventive and corrective maintenance requirements, which greatly influence both the system availability and life cycle cost, need to be defined in order to perform only those preventive actions that are absolutely necessary and costeffective.

7. 20. A Novel Submarine Design Method - Based on technical, economical and operational factors of influence

   Författare :Mats Nordin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parametric and concept; submarine system design; synthesised design model;

   Sammanfattning : The thesis work, with the openly published journal and conference papers, is motivated by theambition to interact over time with the scientific community in the development of a novelcoherent submarine design method to regain momentum in Swedish submarine computeraided Simulation Based Design (SBD). The work was initially stimulated by an earlyobservation in our submarine engineering community, that the existing knowledge of navalarchitecture and systems theory including cost prediction and operational analysis was notcoherently utilised for the design of Naval Integrated Complex System (NICS), hence theneed for a coherent approach.
