3. 2. Investigation of Methods to Improve PZT Sol-Gel Deposition Process for Energy Harvesting Applications

   University essay from KTH/Hälsoinformatik och logistik

   Author : Mikael Granberg; [2022]
   Keywords : PZT; sol-gel; self-polarization; seed layer; titanium oxidation; PZT; sol-gel; självpolarisering; seedlager; titanoxidering;

   Abstract : The purpose of this work was to investigate ways to modify Silex sol-gel deposition of PZT (PbZrxTi(1-x)O3, Lead Zirconate Titanate) in order to improve its properties for energy harvesting applications. A number of methods to improve the figure of merit for energy harvesting (FOM= e312/ε), cause self-polarization, increase lifetime, reduce cost, increase throughput or simplify processing were tested.

4. 3. Neural Networks for Credit Risk and xVA in a Front Office Pricing Environment

   University essay from Lunds universitet/Matematisk statistik

   Author : Isabelle Frodé; Viktor Sambergs; [2022]
   Keywords : xVA; CVA; OTC; Counterparty Credit Risk; Interest Rate Swaps; Hull-White Model; Machine Learning; Artificial Neural Networks; Gated Recurrent Units; Mathematics and Statistics;

   Abstract : We present a data-driven proof of concept model capable of reproducing expected counterparty credit exposures from market and trade data. The model has its greatest advantages in quick single-contract exposure evaluations that could be used in front office xVA solutions. The data was generated using short rates from the Hull-White One-Factor model. READ MORE

5. 4. Learned Multi-Sensor Indoor Positioning of Mobile Devices

   University essay from Lunds universitet/Matematik LTH

   Author : Christoffer Kjellson; [2021]
   Keywords : Indoor Positioning; Deep Learning; Fingerprinting; RSSI; Machine Learning; Pedestrian Dead Reckoning; Kaggle; Sensor Fusion; SDAE; LSTM; Technology and Engineering; Mathematics and Statistics;

   Abstract : Attenuation of the microwave signal used in the Global Positioning System (GPS) due to interaction with building structures complicates the task of accurate indoor positioning. For this reason, research on alternative approaches is being performed at universities and companies worldwide. READ MORE

6. 5. MobilePose: Real-Time 3D Hand Pose Estimation from a Single RGB Image

   University essay from Lunds universitet/Matematik LTH

   Author : David Larsson; Sofie Hellmark; [2020]
   Keywords : 3D hand pose estimation; real-time; Convolutional neural networks; Image analysis; Machine learning; AR; Mathematics and Statistics;

   Abstract : Estimating 3D hand poses from RGB images is a challenging task. In this work we construct efficient neural networks to regress sparse 3D skeletons consisting of 21 keypoints in the hand. Additionally heatmaps are regressed to locate the keypoints in 2D. READ MORE
