  3. 2. Modelling and Investigation of Control of a Power Infrastructure Resource Management System for a Radio Base Station : A study on sustainable power management for ICT infrastructure.

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustav Lenart; [2023]
    Keywords : Hybrid Dynamical Systems; Resource Management; Hybrid Automaton; Sustainable solutions for Wireless technology; Hybrid Dynamiska System; Resurshantering; Hybrid Automaton; Hållbara lösningar för trådlös teknologi;

    Abstract : In order to minimize greenhouse gas emissions and operational cost related to the ICT-infrastructure the power management method of a Radio Base Station (RBS) or Base Transceiver Station (BTS) at Ericsson is studied and modelled. The major load demand at RBS’s are due to uplink and downlink data traffic. READ MORE

  4. 3. Hydrogen Absorption in Metal Hydrides : Transmission of light in relation to hydrogen concentration and site occupancy of ultrathin vanadium films

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : David Sörme; [2022]
    Keywords : metal hydrides; iron-vanadium superlattice; hydrogen; hydrogen site occupancy; hydrogen concentrationm; hydrogen storage;

    Abstract : In this study the effect of hydrogenation on the optical properties in the wavelength range 400-1023 nm of an ultrathin iron-vanadium superlattice is investigated. Specifically, mea- surements of transmission are performed under different states of hydrogenation, along with measurements of absolute hydrogen concentration and hydrogen site occupancy. READ MORE

  5. 4. Techniques for characterization and quantification analysis of foulant deposition in Alfa Laval’s high-speed separators : A literature study

    Keywords : Dairy foulant; Marine foulant; Characterization; Quantification; Stainless steel; surface; analysis;

    Abstract : Alfa Laval is a global company that provides solutions, products, and services for industry, such as high-speed separators for marine and food-application. Foulant deposition on the stainless-steel surfaces of Alfa Laval’s high-speed separators has shown to result in lowering of the separation efficiency. READ MORE

  6. 5. Investigating and Modeling Uplink Processing in 5G NR Multisector Scheduler Simulator

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Oskar Nygren; Axel Sneitz-Björkman; [2022]
    Keywords : Technology and Engineering;

    Abstract : As the latest generation of wireless access technology called Fifth Generation (5G) New Radio (NR) evolves, computational efficiency is key to keep low cost and flexible deployments for vendors. Understanding how the Digital Signal Processing (DSP) load behaves in the digital units is one aspect to enable this efficiency. READ MORE
