Estimating atrial activity in epicardial electrograms: a beamforming perspective

The most common serious heart rhythm disease is atrial fibrillation. It is not fatal on its own but does increase the risk of heart failures and strokes. There is little understanding about the mechanisms behind the disease, so more insight is desired. Using an array of electrodes, measurements are being performed of the electrical atrial...

Integrating Ultrasound Neuromodulation and Imaging: A System Concept for a Non-Invasive Image-Guided Vagus Nerve Stimulator

Vagus nerve stimulation (VNS) has been proven to be an effective treatment for patients suffering from drug­-resistant epilepsy. Current vagus nerve stimulators are either implantable devices or bulky, handheld devices. The implant consists of a pulse generator beneath the skin of the chest, connected to electrodes that are wired to the cervical...

eVTOL Design Propulsion System

In this thesis, a closer look will be taken into the design of a propulsion system of an eVTOL (electric Vertical Take-off and Landing aircraft). The primary goal of the eVTOL is to maximize the payload for a given maximum take-off weight and the eVTOL has to go into service in 2030. To make an as light weight as possible propulsion system, an...

Semi Bistatic Radar: Subgroup - Receiver Antenna

In this thesis, a design of a passive radar for use on a drone used in inhospitable areas where air traffic control is not available due to circumstances. The thesis focusses on the receiver chain and angle of arrival algorithm.

A 10 Gbps Wireline Transceiver Link: To Interface Future RF-DACs

This thesis presents the development of circuits and systems for fast wireline transceiver links that will enable a move towards highly integrable RF digital-to-analog converters. A new perspective on the analysis of bit error rates in wireline links leads to the PAM spectral design space chart: a novel, visual system design analysis tool for...

Bi-Static Sense and Avoid System for Drones (BiSAD) – The transmitter

Wings for Aid is a company which develops an airborne aid-delivery system in emergency-struck areas and wants to use the radar system of Selfly to make an autonomously flying system. The goal of this project is to optimise the current ground-based radar system of Selfly for this application. This is done through the design of a Bi-static radar...

Bi-Static Sense and Avoid System for Drones: Signal Design

In the context of the Bachelor Graduation Project at the Delft University of Technology Department of Electrical Engineering, we have been tasked with a project to design prototype of a bi-static radar. This thesis describes the waveform design of a bi-static radar system and its implementation with Software Design Radio, SDR for short. The...
