1. Suppression of Li-ion Battery Fires
Master-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

2. Läkande av kapitalbrist - något om kapitaltillskott och dess återbetalning
Kandidat-uppsats, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakultetenSammanfattning : The essay deals with topics related to the rules on compulsory liquidation due to lack of capital in Chapter 25, Sections 13-20 of the Swedish Companies Act (ABL), primarily focusing on how capital deficiency can be remedied through various forms of capital injections and how these can be repaid to the contributor. In NJA 1988 p. LÄS MER
3. Generell metod för analys av pesticider med HS-SPME i kombination med GC-MS : Möjligheten att identifiera pesticider i känd lösning och i förgiftningsfall
Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : This study focuses on a general method that has been developed for the identification of both polar- and nonpolar pesticidespolar pesticides in a known solution from EPA 8151 Herbicide acid mix by Merck including the ordered non-polar pesticide Prosulfocarb. The EPA-solution contains 16 analytes that has been completely identified when derivatized and spiked in acetone. LÄS MER
4. Analysis of Hall effect thrusters using Hybrid PIC simulations and coupling to EP plume
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : In the last 30 years, numerical models have been developed to properly analyze Hall eect thrusters (HET),leading to a bridge between analytical prediction/empirical intuition and experiments. For companies in thespace sector, these codes serve to much more than simply simulating the thruster, but it provides a fast, cheapand reliable tool for processes such as validation and verication procedures, as well as for technical developmentof the thruster.

5. Design of Resonant Filters for AC Current Magnification : Heating of Li-ion Batteries by Using AC Currents
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Using alternating current in order to heat batteries at sub-zero temperatures is a method,which is investigated in-depth by an increasing number of study groups. The thesis considersthe resonance phenomenon with the intention to use alternating current amplificationand battery’s impedance in order to induce power dissipation inside the battery, and in thisway increase its temperature.
