de Jong, Mo (author)Rivers play a crucial role in shaping landscapes and supporting ecosystems. This is demonstrated by the tiger habitats in and around Bardia National Park in West-Nepal, which rely on the Karnali River. This study contributes to a larger effort aimed at sustainably managing these tiger habitats. Monitoring the rivers in this remote area is...master thesis 2023

Dai, Jie (author)In ultrasound imaging systems, a charge-sharing successive-approximation-register (SAR) ADC has benefits over a charge-redistribution SAR because the charge-sharing SAR is organically compatible with the subarray beamformer which is deployed to reduce the large channel count. Besides, the noise-shaping (NS) SAR is a promising candidate for...master thesis 2023

Therias, Adele (author)The production of cocoa beans contributes to 7.5% of European Union (EU) driven deforestation. For this reason, the recent European Union Deforestation-free Regulation (EUDR) requires producers to perform comprehensive tracking of cocoa farm extents. However, cocoa crops present unique detection challenges due to their complex canopy structure,...master thesis 2023

WEI, LAI (author)3-D ultrasound imaging using a 2-D array provides much more information about our body than conventional 2-D imaging. However, due to the large number of elements in a 2-D array, channel count reduction is required and the power and area budget for each element is limited. It is quite challenging to design an ultrasound interface circuit with...master thesis 2023

KONG, Fanhao (author)This thesis developed a forward model for Sentinel-1 C-band co-pol and cross-pol backscatter and coherence using crop biophysical variables including leaf area index, tops weight, surface soil moisture and root zone soil moisture as inputs for sugarbeet. These input variables are simulated using a crop model called Decision Support System for...master thesis 2023

Falckenheiner Soria, Sebastian (author)Synthetic Aperture Radars (SAR) have demonstrated to be great instruments for space-based Earth observation in the microwave frequency. Metasurface antennas, on the other side, are a new type of planar antennas with a great potential for space applications, as they are compact and easy to produce. Several methods have been developed in the past...master thesis 2022

Yang, Hankai (author)Time-of-Flight (ToF) is an optical range detection technique that derives range from the round-trip time of light pulse between the imager and the target. Due to the simple hardware and distance extraction algorithm, ToF imagers are widely adopted in existing (automotive, consumer electronics, etc.) and emerging (AR/VR, etc.) applications...master thesis 2022

Mantri, Devashish (author)Since the unravelling of the Covid-19 pandemic, studying methods of virus inactivation have become more important than ever. Many studies focus on the chemical and optical methods of inactivation. Very limited work has been carried out in studying the electrical methods of virus inactivation. The work presented in this thesis attempts to pioneer...master thesis 2022

Jiang, Shilian (author)This article uses Sentinel-1 satellite images to identify rice fields in Rwanda from 2017 to 2021 in an attempt to derive the current status of rice in Muvumba catchment, in the northern part of Rwanda. The timing of rice cultivation in each season in that area was identified as not homogeneous, but generally aligned with the local rainy season....master thesis 2022

Stikkers, Anastasia (author)This thesis provides knowledge on factors affecting the representativeness of wastewater-based epidemiology (WBE) for monitoring the SARS-CoV-2 virus. The application of WBE to monitor health parameters has become essential due to the COVID-19 outbreak in March 2020. WBE is a well-known method to track the SARS-CoV-2 virus in wastewater and is...master thesis 2022

MOU, Jixuan (author)A photoplethysmogram (PPG) is an important optically-obtained bio-signal that enables convenient daily monitoring of heart rate and oxygen saturation (SpO2). Most state-of-the-art PPG sensing systems require an off-chip photodiode, and the photodiode's output parasitic capacitance limits the power-noise trade offs. The objective of this project...master thesis 2022

Zitman, Jelle (author)Antarctic ocean temperatures are rising due to climate change, causing land ice to melt at increasingly higher rates. Ice shelf bottom melt is a key factor responsible for Antarctic ice mass loss and as such understanding melt processes in the Antarctic is therefore key to more accurately predict how the global sea level will respond to climate...master thesis 2022

Olberts, Ernst (author)In this thesis, the achievable performance and limitations of a Synthetic Aperture Radar (SAR) seeker on an Anti-Ship Ballistic Missile (ASBM) for a set of parameters has been investigated. This was achieved by modelling the dynamics of an ASBM and the constraints related to the acquisition requirements of a maritime surface target in the ...master thesis 2022

Liu, Marvin (author)The airborne transmission of SARS-CoV-2 in educational buildings has raised concerns during the current COVID-19 pandemic. In this study, a portable fog generator system was designed and assembled to visualise the airflow pattern of exhaled droplets in a classroom. The system consists of five components: medium, fog generator, buffer, pump, and...master thesis 2021

Caljouw, Denise (author)Dikes hold back water and protect the land behind it from flooding. Due to rising sea levels, land subsidence and more extreme weather patterns, the function of dikes become increasingly important. To ensure dike safety, dikes are regularly inspected. With about 22,500 kilometers of dikes in the Netherlands, this is a very slow, costly and time...master thesis 2021

Mehrotra, Shubham (author)Analog-to-Digital Converters (ADCs) used in high fidelity audio applications require high linearity and a wide dynamic range (>100 dB). Moreover, for use in portable electronic devices such as smartphones, tablets, and hearing aids, these ADCs must also achieve high energy efficiency. This requirement of high linearity and high energy...master thesis 2021

O'Driscoll, Owen (author)Oceans play a vital role in the regulation of Earth's intricate climate system. The majority of gas and energy exchanges occurring at the ocean-atmosphere interface are driven by small-scale, O(1 km), coupled processes. Despite its importance, too few observations have been able to capture the ocean-atmosphere coupling at scales smaller than O...master thesis 2021
