  1. 6. Advanced Side-Channel Analysis of USIMs, Bluetooth SoCs and MCUs

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

    Author : Martin Brisfors; [2021]
    Keywords : Side Channel Attack; Deep Learning; AES; USIM; Milenage; Screaming Channels; Transformer; Security; Sidokanalsattack; Djupinlärning; AES; USIM; Milenage; Screaming Channels; Transformer; Säkerhet;

    Abstract : The use of deep learning for side channel analysis has shown a lot of success in recent years. Impressive results have been presented by many researchers. However, critics of this approach have voiced concerns about the ad hoc methodologies and bespoke neural network designs used in many presented approaches. READ MORE

  3. 7. Investigating Particle Cracking in Single- and Polycrystalline Nickel-Rich Cathodes using In Situ Impedance Spectroscopy

    University essay from Uppsala universitet/Strukturkemi

    Author : Mattias Sjödin; [2021]
    Keywords : Electrochemical surface area; particle cracking; NMC811; transmission-line model; equivalent-circuit fitting; commercial Li-ion batteries;

    Abstract : State-of-the-art Li-ion cathode materials are based on LiMO2 (M=Ni, Mn, Co) layered transition metal oxides (denoted NMC) with Ni-rich composition because of their high specific capacity. Yet, these materials suffer from poor capacity retention due to crack formation during de-/lithiation cycling. READ MORE

  4. 8. Parametrization of a Lithium-ion battery

    University essay from KTH/Kemiteknik

    Author : Elsa Arksand; [2021]
    Keywords : Parametrization; LiFePO4; Single particle model; Li-ion battery; Pseudo-OCV; Parametrisering; LiFePO4; Singlepartikelmodell; Litiumjonbatteri; Pseudo-OCV;

    Abstract : Batterimodeller används för att representera batterier. För ändamål som batterihanteringssystem används idag främst empiriska modeller som representerar ett batteri med en motsvarande kretsmodell. Några nackdelar för dessa modeller ligger i dess oförmåga att simulera interna tillstånd och en tidskrävande parametriseringsprocess. READ MORE

  5. 9. A Digital Test Bench for Pneumatic Brakes

    University essay from KTH/Spårfordon

    Author : Bastian Schick; [2021]
    Keywords : Compressed air brake; Freight train; Modular simulation; Pneumatics; Railways; System modelling; Tryckluftsbroms; Godståg; Modulär Simulering; Pneumatik; Järnväg; Systemmodellering;

    Abstract : This master’s thesis covers the structuring and implementation of a digital testbench for the air brake system of freight trains. The test bench will serveto further improve the existing brake models at Transrail Sweden AB. Theseare used for the optimised calculation of train speed profiles by the DriverAdvisory System CATO.

  6. 10. Design of an electric motor (PMSM) & manufacturing lab

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Lama Awawda; [2021]
    Keywords : Permanent magnet synchronous machine; PMSM; Finite element analysis FEA ; FEMM; Hairpin winding; Motor assembly; Prototype;

    Abstract : The thesis presents deals with the design, analysis, test and control of permanent magnetsynchronous motor(PMSM). An analytical model was carried out based on the d-q frame and the equivalent circuit of PMSM, theanalytical model gives an approximation value of the machine parameters and is carried out byequations from the listed references.
