  1. 1. Design of a Carbon Fiber Thermocouple for Elevated Temperature Measurements

    University essay from KTH/Materialvetenskap

    Author : Marcus Holmström; [2020]
    Keywords : Thermocouple; Carbon Fiber; Thermoelectrical; Electromotive Force; Polyacrylonitrile; Rayon; Termoelement; Kolfiber; Termoelektrisk; Elektromotorisk spänning; Polyacrylonitrile; Viskos;

    Abstract : Thermocouples are one of the most commonly used instruments for thermometry at elevated  temperatures. As of today, there are only a few types of thermocouples that are built to withstand a temperature beyond 1600 °C,however they usually have a temperature measurement uncertainty of around 1% at these high temperatures.

  3. 2. Implementation and experimental evaluation of a parameterized PMSynRM model using Matlab and Comsol Multiphysics

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

    Author : Israt Jahan; [2019]
    Keywords : Comsol Multiphysics; eddy-current losses; permanent-magnet synchronous reluctance motors; reluctance; Comsol Multiphysics; virvelströmsförluster; permanentmagnet synkrona reluktansmotorer; reluktans;

    Abstract : This thesis focuses on modelling of the permanent magnet synchronous reluctancemotor (PMSynRM), which has drawn considerable attention by researchers thanks toits high efficiency and wide range of speed operation. Comparisons with measurementsfrom a four-pole PMSynRM with four barriers and 24 stator slots have been carriedout. READ MORE

  5. 4. A geophysical survey (TEM; ERT) of the Punata alluvial fan, Bolivia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Joakim Mårdh; [2017]
    Keywords : electromagnetic; geophysics; TEM; Punata; alluvial fan; Earth and Environmental Sciences;

    Abstract : The Punata alluvial fan, situated in central Bolivia (Valle Alto) between the Altiplano and the lowlands, is an important aquifer for the local rural population. Due to rapid development and population growth in the area, the demand for fresh water has increased in recent year. READ MORE

  6. 5. Dynamics and electronics of a manually chargeable quadcopter for steady-state flight

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Ioannis Kantsaporidis; Sadeq Al-Attar; [2017]
    Keywords : Rechargeable quadcopter; back emf; momentum theory; sustainability; battery performance; thrust; power;

    Abstract : The objective of this thesis is to investigate how the onboard battery of a quadcopter can be charged through manual rotation of its motors, while understanding the resulting aerodynamical forces acting on the rotors during hover, as well as considering the changes in thrust capabilities when the electronic and structural design are altered. A theoretical approach using the momentum theory will present a general understanding of rotor performance whilst describing the correlation between rotor parameters, thrust and mechanical power.
