  1. 1. Design and control of flexible and distributed production systems using digital twins

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Josu Sarriegi Irazustabarrena; Kepa Lezeta Iturbe; [2023]
    Keywords : ;

    Abstract : The ongoing fluctuation in customer demand within the manufacturing industry has led companies to reconsider production lines. Flexibility is an essential aspect to face when dealing with this problem. READ MORE

  3. 2. The evidence base of elevated vacuum and pin-lock suspension system in transtibial prosthetic users: A literature review with a systematic approach

    University essay from Jönköping University/HHJ. Ortopedteknisk plattform

    Author : Louise Dömstedt; Malin Stafås; [2022]
    Keywords : transtibial prosthetics; transtibial suspension method; elevated vacuum; active vacuum; pin-lock;

    Abstract : Aim: This review aims to describe the existing evidence base for using elevated vacuum suspension and pin-lock suspension systems in regards to fluctuations of limb volume, balance, effect on gait (spatial and temporal, kinematic, and kinetic data), and in-socket movement (pistoning and transverse forces). Background: There is a growing population with a TT amputation thus there is an increased demand for TT prosthetic solutions. READ MORE

  4. 3. Operation strategies of using energy storage for improving cost efficiency of wind farms. : Examining emergency power supply and support services.

    University essay from Uppsala universitet/Elektricitetslära

    Author : Philip Lundquist; [2021]
    Keywords : Hydrogen energy storage; Hybrid energy storage; Support services; FCR-N; Emergency power supply;

    Abstract : With the increase in the world energy demand and environmental incentives, renewable energy sources (RES) need to determine their place as some of the primary power sources in future power systems. However, due to uncertain energy production, renewable energy sources cause unbalance in the power system due to the unsynchronized supply and electricity demand. READ MORE

  5. 4. THE POTENTIAL OF A LATENT HEAT THERMAL ENERGY STORAGE : An Investigation on Rocklunda's Sport Facilities

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Anton Egersand; Emil Fransson; [2021]
    Keywords : LHTES; PCM; TES; Al-Si; Latent Heat; High-Temperature PCM; VRE;

    Abstract : The world is ever increasing in its energy usage, making energy that is sustainable and secure harder to achieve. To fulfil the Paris agreement to limit global warming, the world needs to transition from fossil fuels toward more renewable energy sources, like wind and solar, but these sources have fluctuation in supply which often create a mismatch with demand.

  6. 5. Analysis Of A Wave Power System With Passive And Active Rectification

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Ferdus Wahid; [2020]
    Keywords : WEC; Optimal damping coefficient; Power smoothing; Passive rectifier; Active rectifier; Buck converter; Bi-directional DC-DC converter; Flywheel; Battery; Bi-directional voltage source converter; Voltage source inverter;

    Abstract : Wave energy converter (WEC) harnesses energy from the ocean to produce electrical power. The electrical power produced by the WEC is fluctuating and is not maximized as well, due to the varying ocean conditions. As a consequence, without any intermediate power conversion stage, the output power from the WEC can not be fed into the grid. READ MORE
