  1. 6. Turing's model for pattern formation

    University essay from KTH/Fysik

    Author : Oskar Forsström; Oskar Falgén Nikula; [2022]
    Keywords : Reaction-diffusion; Turing pattern; morphogen; Grier-Meinhardt; Schnakenberg; numerical analysis; minimum energy control;

    Abstract : In an attempt to describe how patterns emerge in biological systems, Alan Turing proposed a mathematical model encapsulating the properties of such processes. It details a partial differential equation governing the dynamics of two or more substances, called morphogens, reacting and diffusing in a specific manner, in turn generating what has now come to be denoted as Turing patterns.

  3. 7. Efficient High-level Synthesis Implementation of massive MIMO Processing on RFSoC

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

    Author : Sijia Cheng; [2022]
    Keywords : Technology and Engineering;

    Abstract : Massive multiple-input multiple-output (MIMO) refers to a wireless access technology that equips base station (BS) with hundreds to thousands of antennas to serve tens of user equipment (UE) in the same time-frequency resource. These extensive antennas improve spectral and energy efficiency, but the detection algorithms tend to be more complex with operations, multiplications, and inversions on larger size matrix.

  4. 8. Modelling of contacts in Adams flex bodies using Mamba

    University essay from KTH/Fordonsdynamik

    Author : Shashwat Joshi; [2021]
    Keywords : Contact simulation; Mamba; Joint Interface Modes; Leaf spring modelling; Frame-subframe contact; ODS analysis; PSD; Kontaktsimulering; Mamba; gemensamma gränssnittslägen Joint Interface Modes ; bladfjädermodellering; ram-subramkontakt; ODS analys; PSD;

    Abstract : Simulations are a powerful tool used to reduce development time and cost in the vehicle industry. However, the models used in simulations are simplifications of reality, and there are commonly contradicting requirements between accuracy and computational efficiency. READ MORE

  5. 9. Hybrid Power System for Green Telecom Sites

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Giovanni Screpanti; [2021]
    Keywords : ;

    Abstract : Solar Photovoltaic can offer a clean and cheap alternative to the Diesel Generator for telecom sites that are in remote locations with no grid coverage or where the grid is not fully reliable. Ericsson Enclosure & Power is looking into the opportunity to integrate this technology, together with battery storage, into their network sites around the globe, in view of a constantly growing network demand and the diffusion of the 5G technology.

  6. 10. Evaluation of the Impact of X-ray Tube Voltage and Filter Thickness on the Performance of Spectral Photon-Counting Detectors

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Cassandra Mannila; Marcus Larsson; [2021]
    Keywords : Photon Counting Detectors; X-ray Tube Voltage; Filter Thickness; Detective Quantum Efficiency; Optimizing; Fotonräknande detektorer; Rörspänning; Filtertjocklek; DQE; Optimering;

    Abstract : During the past years photon-counting detectors (PCDs) have emerged as an alternative to conventional energy-integrating detectors and may significantly improve the standard of care for computed tomography (CT). There are two main alternatives for the material of the detector: cadmium telluride (CdTe) and silicon (Si). READ MORE
