  1. 1. Analysis of Hybrid Offshore Floating Wind and Marine Power

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Sai Varun kollappillai Murugan; [2018]
    Nyckelord :;

    Sammanfattning : Wind energy is a major part of renewable energy production. With fossil fuel depletion and climate change at the cusp, it is an absolute need to implement or evolve the current source or utilization of renewable energy. The wind has been dominating the onshore for many decades and offshore wind turbines are available at shallow depths. LÄS MER

  2. 2. Engine and Gearbox Thermal Management Modeling

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Amaury Arlotto; [2018]
    Nyckelord :;

    Sammanfattning : In order to improve the global efficiency of an engine within the French company Groupe PSA, a research axis focuses on gearbox thermalmanagement for a quicker reduction of its own friction losse after a cold start. The principle remains in deriving a little part of the coolant energy towards the gearbox – until now heated by its own internal frictions – as long as the impact on the engine warm-up is low enough for a global final gain.

  3. 3. CORE RIGIDITIES AND INCUMBENT INERTIA: A STUDY ON THEIR DYNAMICS AND RELATION TO BUSINESS MODEL CHANGE

    Magister-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Valentin Jalba; Charanleen Kaur; [2018]
    Nyckelord :Business Model; Business Model Change; Reactive Change; Incumbent Inertia; Core Rigidities; Implied Inertia; Voluntary Inertia; Business and Economics;

    Sammanfattning : This article adds to the understanding of incumbent inertia through the conceptual separation between voluntary inertia and implied inertia, and the analyzed dynamics of each in relation to core rigidities. Consequently, core rigidities are conceptually shown to be separate from incumbent inertia, concepts which are often confused in extant literature. LÄS MER

  4. 4. Energy Efficiency and Power Consumption Improvement of IR Illumination for Surveillance Cameras

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carlos Tormo Lluch; [2018]
    Nyckelord :rolling shutter; energy efficiency; IR; stroboscopic illumination; rullande slutare; energieffektivitet; IR; stroboskopisk belysning;

    Sammanfattning : The power and energy optimization of a device can lead to a reduced cost, smaller area, better temperature performance, and higher lifetime. Furthermore, in systems that have limited power budget, it allows running simultaneously more functionalities or using features that require higher power demand. LÄS MER

  5. 5. Setup for residual magnetic field measurements in cryostats

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/FREIA

    Författare :Carl Filip von Ehrenheim; [2018]
    Nyckelord :Cryostat; hall probe; magnetometer; pcb;

    Sammanfattning : This thesis covers considerations regarding commercially availble magnetic field sensors and the design work and assembly of a 3-axis magnetic field sensor of Hall technology that is tested for use in a cryostat at the FREIA laboratory, Uppsala university. The assembled sensor needs to withstand cryogenic temperatures and a high vacuum environment. LÄS MER
