  1. 1. Small scale VTOL aircraft using only one lift-producing motor : A study of lift capacity for a Vertical Take-Off and Landing capable aircraft

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

    Author : Daniel Milenkovic; [2023]
    Keywords : Aircraft; VTOL; EDF; Mechatronics; Ardupilot; Luftfarkost; VTOL; EDF; Mekatronik; Ardupilot;

    Abstract : The usage of unmanned aerial vehicles in applications such as terrain mapping and surveillance is proliferating in the modern world. This project aims to investigate the feasibility, in terms of payload capacity and stability, of small scale winged aircraft that have the ability to lift and land vertically, while also being able to transition to normal forward flight using wings for primary lift.

  3. 2. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

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

    Author : Tanmmay Rout; [2023]
    Keywords : Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

    Abstract : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

  4. 3. Evaluating clustering techniques in financial time series

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Johan Millberg; [2023]
    Keywords : clustering; machine learning; financial time series; time series; unsupervised learning; cluster validation; cluster evaluation; klustring; klusteranalys; finansiella tidsserier; maskininlärning; klustervalidering; evalueringsteknik;

    Abstract : This degree project aims to investigate different evaluation strategies for clustering methodsused to cluster multivariate financial time series. Clustering is a type of data mining techniquewith the purpose of partitioning a data set based on similarity to data points in the same cluster,and dissimilarity to data points in other clusters.

  5. 4. The Arab Spring, the rise of terrorism in the Sahel and the evolution of peace and counterterrorism operations in the region : A case study of Mali and neighbouring countries and how peace and counterterrorism operations adjusted to the rise of terrorism in the region

    University essay from Uppsala universitet/Teologiska institutionen

    Author : Maria Maio; [2023]
    Keywords : terrorism; Arab Spring; Sahel; failed states; ungoverned spaces; peace and counterterrorism operations; war on terror; development-security nexuss;

    Abstract : The Arab Spring led to the overthrow of multiple authoritarian regimes in the Middle East and North Africa and to the flow of arms and fighters from Libya to Western African countries, triggering the crisis in the Sahel and altering the security landscape of the region. The Sahel, a quite stable region, became vulnerable to the rise of terrorism due to political instability, internal conflicts dynamics and power vacuum which led to ungoverned spaces to be seen as safe havens to terrorist groups.

  6. 5. Fast deep discharging using a controllable load as pretreatment for EV battery recycling : A study on efficacy, speed, and safety

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

    Author : Lucas Van Genechten; [2023]
    Keywords : Recycling; lithium-ion battery; deep discharging; external short-circuit; internal pressure; thermal stability; Electrochemical impedance spectroscopy; Återvinning; litiumjonbatteri; djupurladdning; extern kortslutning; internt tryck; termisk stabilitet; electrochemical impedance spectroscopy;

    Abstract : In response to the present and projected growth of the EV industry, the development of a large-scale, reliable and efficient lithium-ion battery recycling sector is vital to ensure circularity of the embedded valuable metals and ensure overall sustainability of the technology. One of the main recycling procedures under development is based on hydrometallurgy. READ MORE
