1. Numerical Simulations of Resonant Tunnelling Diodes
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).

2. Physiology-Guided Machine Learning for Improved Reliability of Non-Invasive Assessment of Pulmonary Hypertension
University essay from Linköpings universitet/Avdelningen för medicinsk teknikAbstract : Diagnosing pulmonary hypertension (PH) with right heart catheterization (RHC) is associated with a risk for complications and high expenses, leading to late diagnoses [1]. Transthoracic echocardiography can be used to assess non-invasive indicators for PH such as right ventricular systolic pressure (RVSP), which can be estimated by combining the peak tricuspid regurgitation velocity (TRV) with the estimated right arterial pressure (RAP).

3. Carabids as weed seed control agent : impact of soil cultivation on carabid weed seed regulation
University essay from SLU/Dept. of Crop Production EcologyAbstract : As weed seed predators, carabid beetles can regulate the weed seed bank within agricultural fields. Little is anyhow known about how weed seed bank regulation by carabids is affected by different tillage treatments with decreasing intensity, why this was here examined. READ MORE

4. Exploring Normalizing Flow Modifications for Improved Model Expressivity
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Normalizing flows represent a class of generative models that exhibit a number of attractive properties, but do not always achieve state-of-the-art performance when it comes to perceived naturalness of generated samples. To improve the quality of generated samples, this thesis examines methods to enhance the expressivity of discrete-time normalizing flow models and thus their ability to capture different aspects of the data.

5. Verification Method for Time of Capture of a Rolling Shutter Image
University essay from Linköpings universitet/Databas och informationsteknikAbstract : Modern automotive systems increasingly depend on camera sensors to gather safetycriticaldata used in driver-assisting features of the system. These features can consist offor example, lane-keeping assist and automatic braking where the sensors register objectswithin certain distances. READ MORE
