  1. 1. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size

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

    Author : Md Mamunur Rashid; [2023]
    Keywords : LTE-V2X; aperiodic; variable size; CAM; Technology and Engineering;

    Abstract : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

  3. 2. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Douglas Björkengren; [2023]
    Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

  4. 3. Frequency Stabilization in low Inertia Systems With Battery Power Injections

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

    Author : Leif Lundin; [2023]
    Keywords : ;

    Abstract : The challenges for the power system of the future becomes increasingly larger when large amountsof renewable energy sources are integrated, and when conventional forms of power such asnuclear power are phased out. This results in a greater difficulty in quickly deploying FrequencyContainment Reserves in the event of of power balance disturbance, to stabilize frequency andvoltage. READ MORE

  5. 4. "Another taboo has fallen" : Navigating the European Peace Facility post the Russian aggression against Ukraine

    University essay from

    Author : Alfred Häger; [2023]
    Keywords : CFSP; EPF; European Union; Ukraine; Pattern Matching;

    Abstract : In March 2021, the EU launched the European Peace Facility (EPF), a financial instrument that allows the EU to commonly fund peacekeeping and military missions. However, following the Russian aggression against Ukraine on the 24th of February 2022, the EPF has primarily been used to provide Ukraine with lethal military equipment. READ MORE

  6. 5. Centralised MPC for Long-term Voltage Stability Control of Power System

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

    Author : Johan Hallberg; [2023]
    Keywords : Voltage stability; Model predictive control; Tap-changing transformer; Capacitor bank; Spänningsstabilitet; Model prediktiv reglering; Lindningskopplare; Kondensatorbank;

    Abstract : In a power system it is important to keep voltages at specific levels at network buses. Deviations from that can lead to reduced efficiency of transferred power or, in more severe cases, widespread power outages affecting large parts of society. There exists a variety of power system devices that have the ability to regulate the voltage levels. READ MORE
