Cryptanalysis of IEEE 802.11i TKIP
(Master thesis, 2009)The Temporal Key Integrity Protocol (TKIP) was created to fix the weaknesses of Wired Equivalent Privacy (WEP). Up until November 2008, TKIP was believed to be a secure alternative to WEP, although some weak points were ... -
Crystalline symmetry controlled magnetic switching in epitaxial (111) La0.7Sr0.3MnO3 thin films
(Journal article; Peer reviewed, 2015)Mixed-valence manganite thin films are attractive for spintronic devices. Crystalline orientation is a promising route to tailor switching mechanisms, as magnetization reversal depends on the magnetic anisotropy. Here, ... -
CubeDMA-Optimizing Three-Dimensional DMA transfers for Hyperspectral Imaging Applications
(Journal article; Peer reviewed, 2018)Onboard computing is one of the principal needs in space-related technology in the recent years. In particular, onboard hyperspectral imaging (HSI) processing has advanced significantly. Due to advances in sensor technology, ... -
CubeSats in University: Using Systems Engineering Tools to Improve Reviews and Knowledge Management

Current Trends for State-of-Charge (SoC) Estimation in Lithium-Ion Battery Electric Vehicles
(Peer reviewed; Journal article, 2021)Energy storage systems (ESSs) are critically important for the future of electric vehicles. Despite this, the safety and management of ESSs require improvement. Battery management systems (BMSs) are vital components in ESS ... -
Current-Mode SAR-ADC In 180nm CMOS Technology
(Master thesis, 2012)This thesis presents a fully differential 9-bit current-mode successive approximation (SAR) ADC. The circuit is designed in 0.18 um technology with 1.8 V supply voltage and has a current draw on 472 uA. The ADC has a ... -
Custimisable waveform generator
(Master thesis, 2022)A waveform is a set of signals that helps drive and control different parts of digital designs. To create a waveform a waveform generator is needed. This generator can be implemented in many different ways depending on the ... -
DAB Radio Receiver using GNU Radio
(Master thesis, 2015)DAB radio, a digital replacement of FM radio, coverage is expanding. Receiver design using radio amateur equipment hasn't been much explored. This master's thesis explores the use of a DVB-T dongle, GNU Radio and a simple ... -
Data Acquisition with Unmanned Aerial Vehicle (UAV) from Floating Sensor Nodes
(Master thesis, 2014)In the last decades an increase in the need for ocean monitoring capabilities has arisen. To be able to meet these requirements a low-cost, automated solution is needed. It should be easy to maintain and to reconfigure as ... -
Data for characterization of the optical properties of Atlantic salmon (Salmo salar) blood
(Peer reviewed; Journal article, 2023)Photoplethysmography is a recent addition to physio-logging in Atlantic salmon which can be used for pulse oximetry provided that the properties for light propagation in salmon tissues are known. In this work, optical ... -
Data Fusion for Subsea Oil Spill Detection Through Wireless Sensor Networks
(Journal article; Peer reviewed, 2020)This work studies the impact of Wireless Sensor Networks (WSNs) for oil spill detection in subsea Oil&Gas applications. The case study is the Goliat FPSO where one WSN with passive acoustic sensors is assumed to be installed ... -
A Data-Driven Architecture for Sensor Validation Based on Neural Networks
(Peer reviewed; Journal article, 2020)In this paper, we propose a novel sensor validation architecture, which performs sensor fault detection, isolation and accommodation (SFDIA). More specifically, a machine-learning based architecture is presented to detect ... -
Data-Driven Classifiers for Early Meal Detection Using ECG
(Peer reviewed; Journal article, 2023)This study investigates the potential of the electrocardiogram (ECG) to perform early meal detection, which is critical for developing a fully-functional automatic artificial pancreas. The study was conducted in a group ... -
Data-Driven Personalized Cervical Cancer Risk Prediction: A Graph-Perspective
(Chapter, 2021)Routine cervical cancer screening at regular periodic intervals leads to either over-screening or too infrequent screening of patients. For this purpose, personalized screening intervals are desirable that account for ... -
A Database for the Radio Frequency Fingerprinting of Bluetooth Devices
