  1. 21. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Simon Pääjärvi; [2022]
    Keywords : Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

    Abstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE

  3. 22. Performance Analysis Of Massive MIMO With Port Reduction

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

    Author : Tingrui Zhang; [2022]
    Keywords : 5G NR; Massive MIMO; Fronthaul; Beamforming; Functional split; 5G NR; Massive MIMO; Fronthaul; Beamforming; funktionell uppdelning;

    Abstract : In centralized radio access network (C-RAN) architecture, the base-band unit (BBU) is connected to one or more remote radio units (RRUs) via a fronthaul (FH) interface. Upgrading base station antennas in C-RAN to support massive multiple-input multiple-output (MIMO) technology can improve network spectral efficiency and largely boost the capacity of the 5G system.

  4. 23. Verification of elastomer characteristics in electro-mechanical linear actuator

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

    Author : Rohit Karmungikar; [2022]
    Keywords : ANSYS; Aging; Hyperelastic; MATLAB and Mooney-Rivlin; ANSYS; Åldrande; Hyperelastic; MATLAB och Mooney-Rivlin;

    Abstract : Cascade Drives develops electromechanical actuators using a rack and pinion configuration to achieve a combination of high load and high-speed operation. A patented load distribution mechanism enables the use of multiple pinions on a single rack, resulting in a compact unit with high positional accuracy capable of absorbing shock loads. READ MORE

  5. 24. Life cycle analysis and comparison of climate impact for two alternative floor systems for increased weight in high-rise timber buildings

    University essay from KTH/Byggnadsmaterial

    Author : Nir Kedem; [2022]
    Keywords : Life cycle assessment; LCA; Anavitor; Environmental impact; Building materials; Timber; Concrete; Gravel; Adding weight system.;

    Abstract : The aim of this Master Thesis is to investigate and quantify the climate impact for two floor system alternatives for the Cederhusen project, that is the 8 floors timber-based buildings located at Sankt Eriksplan in Stockholm. The overall motivation for this study is the fact that the construction industry is a major contributor to the total amount of the global greenhouse gas emissions. READ MORE

  6. 25. Flexibility of electricity usage in private households with smart control : Modelling of a smart control system with the aim to reduce the electricity cost of private households with storage units and photovoltaic systems.

    University essay from

    Author : Marina Pakola; Antonia Arab; [2022]
    Keywords : Smart control of electricity usage; optimization; mixed-integer linear programming MILP ; electricity price forecasting; load forecasting; storage systems in private households; electricity costs in Sweden;

    Abstract : High electricity prices have become the title of several news articles recently in Sweden and the prices have experienced large sudden fluctuations during certain periods. In this thesis work, a smart control model for the electricity usage in three different households has been developed with the main purpose to minimize the electricity cost. READ MORE
