21. Natural sugar as an MRI contrast agent for brain cancer detection using chemical exchange saturation transfer (CEST) imaging at 3T
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Hjärntumörer utgör cirka 2,5% av alla cancerdiagnoser i Sverige (2013) och femårsöverlevnaden är cirka 50%. Hjärntumörer diagnostiseras med bildtagningstekniker såsom datortomografi (CT), positronemissionstomografi (PET) och magnetkamera (MR). READ MORE

22. Developing a spiking neural model of Long Short-Term Memory architectures
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikAbstract : 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.

23. CO and CO2 Detection for Catalysis Diagnosis by Means of PLIF
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikAbstract : In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. READ MORE

24. Adversarial Deep Learning Against Intrusion Detection Classifiers
University essay from Luleå tekniska universitet/DatavetenskapAbstract : Traditional approaches in network intrusion detection follow a signature-based ap- proach, however the use of anomaly detection approaches based on machine learning techniques have been studied heavily for the past twenty years. The continuous change in the way attacks are appearing, the volume of attacks, as well as the improvements in the big data analytics space, make machine learning approaches more alluring than ever.

25. Investigation of phase conjugation for medical imaging
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/AtomfysikAbstract : With the development of extremely precise spectral filters based on spectral hole burning and slow light effects, the idea of their implementation in an Ultrasound Optical Tomography (UOT) medical imaging technique arose. Simulations have shown that the resulting Contrast-to-Noise (CNR) ratio is fairly good at depths up to 5 cm but decreases dramatically when probing deeper in tissue. READ MORE
