  1. 21. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Vidar Flodgren; [2019]
    Keywords : GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

    Abstract : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. READ MORE

  2. 22. Towards disease progression sub-typing via responsibility sampling for robust expectation-maximisation learning

    University essay from KTH/Optimeringslära och systemteori

    Author : Mathias Edman; [2019]
    Keywords : ;

    Abstract : Most diseases have different heterogeneous effects on patients. Broadly, one may conclude what manifested symptoms correspond to which diagnosis, but usually there is more than one disease progression pattern. READ MORE

  3. 23. Developing a spiking neural model of Long Short-Term Memory architectures

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Isabella Pozzi; [2018]
    Keywords : Physics and Astronomy;

    Abstract : Current advances in Deep Learning have shown significant improvements in common Machine Learning applications such as image, speech and text recognition. Specifically, in order to process time series, deep Neural Networks (NNs) with Long Short-Term Memory (LSTM) units are widely used in sequence recognition problems to store recent information and to use it for future predictions.

  4. 24. Investigation of Mode Superposition as Modelling Approach for Crankshaft Torsion

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Jonas Johansson; [2018]
    Keywords : Torsion; Crankshaft; Modal analysis; Mode superposition;

    Abstract : With tougher emission standards for heavy duty trucks, good control of the engine is of importance. By taking into consideration the torsional vibrations occurring in the crankshaft, the engine control can be improved. READ MORE

  5. 25. Quantum Speed Limits of Spin Chain Dynamics : Applying Quantum Speed Limits to Spin Chains used as Quantum Channels

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Yonatan Gazit; [2017]
    Keywords : ;

    Abstract : Quantum computers, like classical ones, need to be capable of sending informa-tion between different parts of the computer. Spin chains are one viable method of sending qubits while preserving the superposition and entanglement of a state. READ MORE
