Wassenaar, Arjen (author)The use of geometric anti-springs (GASs) in MEMS accelerometers can not only boost the sensitivity through the static balancing effect, it also introduces the capability to tune the stiffness post-manufacturing by adjusting the balancing force. This paper addresses the challenge of mechanically fine-tuning the stiffness to create the potential...master thesis 2024

Oudhuis, Waded (author)Computers having the ability to estimate intentions to speak can improve human-computer interaction. While plenty of research has been done on next-speaker prediction, they differ from intentions to speak since these rely only on the person themselves. Previous research was done on inferring intentions to speak using accelerometer data with some...bachelor thesis 2023

Stokman, Charlotte (author)The energy market is growing and noise regulations for offshore foundation pile installation grow stricter. New initiatives arise to comply with the ongoing developments in the field, such as the BLUE Piling Technology under development by IQIP. Its features are presented as reduced underwater noise levels during installation, which is attibuted...master thesis 2023

Claassen, Carlijn (author)The combination of the high number and the consequences of falls in older adults led to the development of fall risk assessments; non-sensor-based and sensor-based. Multiple studies used ML for older adults' fall risk prediction using raw IMU data. This study's objective was to develop a DL algorithm that predicts the fall risk of people living...master thesis 2022

Mingione, Fabio (author)Reaction wheels are often the main contributor to microvibrations on satellites. These vibrations are a source of pointing errors and therefore need to be limited as much as possible. The miniaturization trend in the space industry and universities fostered the production of very small reaction wheels, suited to Cubesat and PocketQube scales. A...master thesis 2022

Groenendijk, Mark (author)The goal for this paper is to find out what the smart badge provided by the Social Perceptive Computive Lab (SPCL) group is and what it contains. The sensors that are used in the smart badge are the Accelerometer, Gyroscope and Magnetometer. The main question of this paper is ”What is the benefit of using full 9-DOF IMU data in predicting...bachelor thesis 2022

Remmerswaal, Evan (author)Problem: Due to high rejection rates regarding prostheses’ use, the assessment of the amputee’s use of the prosthesis has become more critical. Today’s prosthesis research is limited to assessing a users’ performance to perform tasks in a controlled environment. Therefore, these studies cannot wholly assess how the prosthesis is used in the...master thesis 2020

Laxminarayanan Raj Prabhu, N. (author)Social interactions in general are multifaceted and there exists an wide set of factors and events that influence them. Hence, interactions as a social phenomena have been studied by researchers in the fields of psychology and social signal processing from different stand points. The common trend in literature is to perform an in-depth study on...master thesis 2020

Mouris, Roel (author)Silicon accelerometers used in the automotive industry should be improved in resolution and accuracy. Exploiting quantum effects in diamond to improve sensing accuracy is a popular technique for nanoscale sensing applications. This thesis will present a new design concept for an accelerometer using these quantum effects for sensing on a...master thesis 2019

van der Wel, Marissa (author)In this thesis the automatic multimodal detection of social and task cohesion in meetings is studied. The presence of social and task cohesion has positive benefits on employee well-being, creativity and productiveness, and can therefore be used to assess meeting quality. Conversational partners imitate each other's body language and speech...master thesis 2019

Suriani, Irene (author)Fluid accumulation in the human body is, in many cases, a symptom of some underlying pathological condition. Most common examples include edema, ascites, pleural effusion, and internal bleeding. Currently available non-invasive methods to assess fluid accumulation in the body are mainly imaging-based (i.e. ultrasound, computed tomography). This...master thesis 2019

Friđriksdóttir, Esther (author)Physical activity and mobility are important indicators of the recovery process of patients in the general ward of the hospital. Currently, monitoring mobility of hospitalized patients relies largely on direct observation from the caregivers. Accelerometers have the potential to quantify physical activity of patients objectively and without...master thesis 2019

Narayanan, Swarna (author)Wireless sensor networks play a vital role in major technological developments. The success of such networks depend on the quality and reliability of data acquisition. Despite a lot of research involving network clock synchronization, the area of synchronous sampling has not been dealt in much detail. This thesis aims at studying and...master thesis 2019

Belis, Sébastien (author)The Equivalence Principle is today challenged by some theories attempting to unify General Relativity and Quantum Mechanics. The MICROSCOPE mission thus intents to confirm or overturn this principle by testing the universality of free fall in space with an unrivaled precision objective of 10^-15. The principle of the test relies on the precise...master thesis 2018

Konsolakis, Kostas (author)Physical activity recognition through wearables has enabled the development of novel applications in healthcare. Most of the existing studies focus on predicting activities using wearable sensors, either in a controlled or uncontrolled environment. However, there is not a clear distinction between these two environments. Hence, this thesis aimed...master thesis 2018

van der Marel, Martijn (author), van der Horst, Casper (author)In order to make offshore working conditions safer, Ampelmann B.V. builds platforms that stay stable by compensating for a ship’s motion. These platforms are controlled via motion reference units (MRUs). In order to test the performances of these MRUs, a linear motion MRU test setup was developed. The system was divided into three parts:...bachelor thesis 2018

Le, T.N. (author)Prototype single layer armour units on a breakwater slope are observed to break. To predict when breakage occurs, the objective of this research project is to obtain knowledge on, and measurements of the rocking behaviour and failure mode of single layer armour units. A single cube on a breakwater slope is subjected to investigations. An...master thesis 2016

Belt, P. (author)The retrieval of vertical winds by using acceleration data of satellites has never been done before and therefore the results will be unique. Two different methods can be developed for the retrieval of these winds. The first one is a two-dimensional approach and the second one uses the three-dimensional space. From the results for the vertical...master thesis 2016

Klein Horsman, F. (author)Vibrations can be a limiting factor in systems working with nanometer precision. Inertial sensors are used to measure these vibrations. This thesis presents a hybrid inertial sensor using both a displacement and velocity measurement on a single mass-spring system. The measurements are combined into one output of absolute displacement. A...master thesis 2016
