Leveraging Fine-grained Telemetry Data for the Detection and Prevention of Vulnerability Exploits

In the modern digital landscape, cybersecurity threats are a significant concern, particularly for publicly accessible computer systems. Vulnerabilities, or flaws in system design, can be exploited by malicious actors to compromise system security and integrity. This paper explores the challenges of handling vulnerabilities in software...

Multi-domain network telemetry solution - Proof of Concept implementation

The inability to check how our Internet traffic is being handled and routed poses all kinds of security and privacy risks. Yet, for the typical end-user, the Internet indeed is such a black box. This thesis, adheres to the call for an Internet that is more transparent, and as a step forward proposes a mechanism that carefully balances the desire...

Development of Telemetry Ranging for Small Satellites: A Ranging technique for Delfi-PQ

Small satellite systems such as CubeSats and PocketQubes have strict requirements in terms of size, weight, and power available onboard. In light of these constraints, small satellite systems typically omit the inclusion of a ranging system due to its power and specialized hardware requirements. However, new research in satellite ranging...

Unmasking Overestimation: A Re-evaluation of Deep Anomaly Detection in Spacecraft Telemetry: A Re-evaluation of Deep Anomaly Detection in Spacecraft Telemetry

As the volume of telemetry data generated by satellites and other complex systems continues to grow, there is a pressing need for more efficient and accurate anomaly detection methods. Current techniques often rely on human analysis and preset criteria, presenting several challenges including the necessity for expert interpretation and continual...

Follow-the-Leader Guidance, Navigation, and Control of Surface Vessels: Design and Experiments

A novel follow-the-leader approach for azimuth-driven vessels is devised and experimentally tested in a model-scale outdoor scenario. The vessels are equipped with global navigation satellite and inertial navigation systems. A line-of-sight algorithm ensures the yaw-check ability of the follower vessel along the leader's path, while a speed...

A 1.66Gb/s and 5.8pJ/b Transcutaneous IR-UWB Telemetry System with Hybrid Impulse Modulation for Intracortical Brain-Computer Interfaces

Intra-cortical extracellular neural sensing is being rapidly and widely applied in several clinical research and brain-computer interfaces (BCIs), as the number of sensing channels continues to double every 6 years. By distributing multiple high-density extracellular micro-electrode arrays (MEAs) in vivo across the brain, each with 1000's of...

An accurate and efficient method to train classifiers for atrial fibrillation detection in ECGs: Learning by asking better questions

Background: An increasing number of wearables are capable of measuring electrocardiograms (ECGs), which may help in early detection of atrial fibrillation (AF). Therefore, many studies focus on automated detection of AF in ECGs. A major obstacle is the required amount of manually labelled data. This study aimed to provide an efficient and...

Deep implant localization and uplink data telemetry using ultrasound

Active implantable devices are conventionally powered with batteries. The miniaturisation of implants necessitates the need to find an efficient way to transfer power wirelessly. Ultrasound energy transfer with its short wavelength, small receiving transducer size, beamforming capability makes deep tissue penetration possible making it a good...

Combined laser ranging and communication on laser terminal CubeCat and TNO’s optical ground station

Laser communication offers high data rates and more bandwidth capacity compared to radio but is also advantageous in terms of power and volume. However, the required pointing accuracy and atmospheric influence pose stringent requirements on the system which form the main challenges for this type of communication. This is where laser ranging...

Digital biomarkers and algorithms for detection of atrial fibrillation using surface electrocardiograms: A systematic review: Digital Biomarkers for AF in Surface ECGs

Aims: Automated detection of atrial fibrillation (AF) in continuous rhythm registrations is essential in order to prevent complications and optimize treatment of AF. Many algorithms have been developed to detect AF in surface electrocardiograms (ECGs) during the past few years. The aim of this systematic review is to gain more insight into...

Unraveling the Electro-Pathophysiology of Atrial Fibrillation: Automated Atrial Fibrillation Analysis in Post-Operative Electrocardiograms

Introduction Atrial fibrillation (AF) is the most common age-related, progressive tachyarrhythmia in the USA and in European countries. AF is associated with an increased risk of stroke, heart failure, impaired cognitive function, and increased mortality. An obstacle for optimal diagnosis and treatment is the relatively unknown (electro-...

Building a GUI for Nuna's Mission Control

In the history of the World Solar Challenge, a six day challenge from Darwin to Adelaide, one car has proved to be dominating: the Nuon Solar Car. A telemetry application played an important role in this, but needed to be updated. This was realised by the new Mission Control application project: "Building a GUI for Nuna's Mission Control". In...

Embedding a telemetry system for sailing athletes on a coaching RIB

In this project, an attempt was made to embed telemetry in one of the harshest environments one can find itself in. The extremeness of the shocks was identified as the most important hurdle to take in order to install an electronic device on a RIB (rigid inflatable boat). Shocks up to 12G in the vertical direction where measured, when the RIB...

Channel coding with the (255,255-2T) Reed-Solomon codes over CF(256)

The class of (255, 255-2T) Reed-Solomon codes over CF(256) is studied in detail. In particular the encoding and decoding algorithms are elaborated. Main computational elements are the discrete Fourier transform for syndrome and error locator computation, Euclid's algorithm for solving the key equation and Horner's scheme for determining the...

Study of an attitude acquisition measurement technique using the ESA starmapper: Part I: Executive summary

The study deals with the rotational motion of a spin-stabilized spacecraft equipped with a V-slit sun sensor and the X-slit ESA starmapper. Assuming complete absence of an a priori attitude estimate, it is required to produce a rough estimate of the spacecraft attitude motion. It was assumed that sensor misalignments, external torques and...
