This study aims to investigate the impact of various denoising algorithms on the quality of visual stimulus reconstructions based on functional magnetic resonance imaging (fMRI) data. While fMRI provides a valuable, noninvasive method for assessing brain activity, the reliability of this data can be impaired by multiple noise types, including...

This paper explores using synthetic noise superimposed on fMRI data to selectively impact the performance of the Generic Object Decoding (GOD) model developed at Kamitani Lab. The GOD model predicts image categories that subjects viewed, based on their recorded fMRI brain activity. To evaluate how selective the noise can be in impacting...

The Kuramoto model (KM) is a well known mathematical model of coupled oscillators that is frequently used to study synchronization phenomena. In this bachelor thesis we investigate the effects of noise on synchronization in Kuramoto-type networks.<br/><br/>In the first part we follow the methods of Maggi and Paoluzzi [1], but include detailed in...

The goal of seismic imaging is to create a model of the subsurface from samples of a transmitted wavefield that is reflected in soil layers.<br/>The created model can be used to locate storage possibilities for CO2 or H2 or to find oil and gas reservoirs or other natural resources.<br/>Seismic imaging relies on the propagation of wavefields,...

As electromagnetic waves cannot propagate sufficiently far in water, underwater communication is mainly performed using either acoustics or optics. However, none of these technologies have been proven to be completely effective in every situation. Therefore, research in new underwater communication systems can still bring large benefits to a...

Although there are many promising applications of a learning curve in machine learning, such as model selection, we still know very little about what factors influence their behaviours. The aim is to study the impact of the inherent characteristics of the datasets on the learning shapes, which are noise, discretized input and dimensionality. We...

Multi-label learning is becoming more and moreimportant as real-world data often contains multi-ple labels. The dataset used for learning such aclassifier is of great importance. Acquiring a cor-rectly labelled dataset is however a difficult task.Active learning is a method which can, given anoisy dataset, identify important instances for...

Multi-label learning is an emerging extension of the multi-class classification where an image contains multiple labels. Not only acquiring a clean and fully labeled dataset in multi-label learning is extremely expensive, but also many of the actual labels are corrupted or missing due to the automated or non-expert annotation techniques. Noisy...

This paper combines the concepts of noise and stability in the iterated prisoner's dilemma. The purpose is to find strategies that score well (have a high cooperation percentage) in a homogeneous noisy environment, but are also robust to invasions. Generally, strategies that perform best under noise are maximally forgiving, however,...

In this research, a learner’s sustained attention in the remote learning context will be studied by collecting data from different sensors. By combining the results of these sensors in a multi-modal analytics tool, the estimation of the learner’s sustained attention can hopefully be improved. This research will mainly focus on microphone...

The concrete bridges constructed in the 1960s and 1970s lack shear reinforcement, rendering them non-compliant with current design regulations. To potentially enhance their shear capacity, the proposed approach involves applying a layer of ultrahigh-performance fiber-reinforced concrete (UHPFRC) on both sides of the normal strength concrete (NSC...

This thesis’s objective was to re-design a weight sensor readout system for Intralox, an international manufacturer of conveyor belts and equipment. Intralox’s current implementation is expensive, too complicated, and inaccurate. After considering several possible readout implementations, an inductively coupled solution with a frequency-based...

This report describes the design of different amplifiers that are part of an FM transceiver. This is part of a larger project, which has the objective to design a complete FM transceiver from discrete components only, meaning that IC technology is not considered. <br/>The circuits designed are two baseband amplifiers, an intermediate frequency...

Interactions in the real world are subject to mistakes and miscommunications. The presence of this noise in interactions challenges cooperation, as one party cannot determine whether the other party did not cooperate on purpose. The Prisoner's Dilemma has commonly been used to study mutual cooperation. Strategies like Tit for Tat that do well in...

MRI images are very useful for detecting diseases, as well as for the treatment of diseases. However, MRI scanners are usually too expensive for developing countries to purchase and maintain. Therefore, a less expensive scanner is being developed at Delft University of Technology and Leiden University Medical Center. Unfortunately, the images...

This Bachelor graduation project has the goal to create a device which is able of automatic volume control, to be used for enhancing speech intelligibility. To tackle the intelligibility of speech through Public Address Systems (PA Systems), an Intelligibility-Enhancing Automatic Volume Control system was proposed. The total system to be made...

At virtually every public venue, announcements for visitors are made via a public addressing system. It is important that announcements transmitted by means of a public addressing system are not only audible, but also well understood by the general public. This thesis covers one of three subsystems required to make<br/>a product that is capable...

This thesis explains the design process of two subsystems of a radio transmitter and receiver. The goal of the project is to transmit audio over a distance using FM modulation. This report will focus on the power amplifier leading to the transmitting antenna and the low noise amplifier connected to the receiving antenna. A design process for a...

Major delivery companies such as DHL, UPS or Amazon have been developing small drones to deliver packages. This alternative to truck delivery is expected to start operating in the near future. The advantages of it are its speed, price, safety and sustainability: parcels would not be subjected to traffic and they would be delivered within an hour...

In this report, the design of a subsystem within a localization system for the Bosch DICENTIS wireless conference system will be presented. The localization system will function by means of using acoustic Time Difference Of Arrival (TDOA) measurements to determine the location of each unit connected to the DICENTIS conference system. By unit,...
