Over the past decade, spatial audio awareness evolved into an in-demand feature in audio entertainment. The addition of sound source locations to, for instance, movies or music adds a level of auditory envelopment and spatial awareness to the audio experience. Expensive setups present in, for instance, cinema's, are able to create this...

Recent advancements in quantification of repair outcomes of CRISPR-Cas9 mediated double-stranded DNA breaks (DSBs) have allowed for the use of machine learning for predicting the frequencies of these repair outcomes. Local DNA sequence context influences the frequencies of mutations that arise when DNA gets repaired after it is targeted by...

We all know the possible consequences of global warming, rising temperatures, flooded cities and destroyed ecosystems. One of the causes is the emission of gases, predominantly CO2, which is increased by the growing E-commerce market. E-commerce companies rely on recommender systems to stimulate users to purchase products. We are convinced that...

The Socially Perceptive Computing Lab (SPCL) at Delft University of Technology has developed a device called the Midge. The aim of this device is to record data of social interactions at conferences. This paper aims to characterise how battery life is affected by different sensor settings on the Midge as well as how much data is generated in a...

In our daily life people encounter many social interactions, for example in the supermarket, at work and in schools. Currently the most reliable way to find social interactions in groups, is to manually annotate the data. Manual annotation takes a lot of time and human resources and as the information stream goes faster and faster, the manual...

Detecting social interactions through wireless wearable Bluetooth devices is increasing in popularity. Devices use the signal strength to other detected devices to estimate the proximity between people and group them together based on the Dominant set algorithm. Dominant sets are a maximal clique of nodes with an edge-weight based on the...

Smoking is a leading risk factor negatively impacting the health of people, not only those partaking in it first-hand, but also to those around them. Different methods are available to assist people with quitting smoking, with various degrees of effectiveness. Researchers developing smoking cessation approaches would like to have controlled...

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...

When analysing social interactions, manual labour is often required to identify what is happening. An automated method of detecting who is interacting with who would already prove to be a significant help. This paper looks at how automated interaction detecting can be established. We look at methods of detecting proximity and look deeper into...

This thesis has researched how the Midge compares to a modern mobile phone regarding the accuracy and reliability of the rotation vector from the DMP in both devices. The rotation of the main axis of the Midge accurately matches that of the modern mobile phone, which means that the accuracy and reliability of the rotation vector from the DMP of...

The Midge is a sensor device developed by the Socially Perceptive Computing Lab (SPCL) at Delft University of Technology (TU Delft). This device is used to monitor human behaviour in social settings using several sensors. In this paper, the accuracy of the Inertial Measurement Unit (IMU) chip used in the Midge sensor package was evaluated. The...

We live in a world where much of our interactions with the environment around us depend on us being physically close to them. For instance, we have proximity­based tokens (e.g., keys and smartcards) for access systems installed at various places such as in cars, at contactless payment terminals, and in electronic passports. Moreover, such...

Parkinson’s Disease (PD), Essential tremor (ET), and dystonia are movement disorders often misdiagnosed as one another and commonly present tremor as one of their motor symptoms. Rates of misdiagnosis between 30 and 50% of ET patients have been reported, where dystonia and PD are the most common missed diagnoses. Additionally, up to 50% of...

Voice messages are an increasingly well-known method of communication, accounting for more than 200 million messages a day. Sending audio messages requires a user to invest lesser effort compared to texting while enhancing the meaning of the message by adding an emotional context (e.g., irony). Unfortunately, we suspect that voice messages might...

Hyperledger Fabric is a permissioned enterprise blockchain allowing organizations to collaborate and automate processes via smart contracts. However, these contracts could contain security vulnerabilities leading to unexpected behavior or other negative consequences. Therefore, this study takes a closer look at three reported smart contract...

GoQuorum is an enterprise blockchain platform that supports smart contracts and allows for private transactions. Smart contracts enable automated payment while eliminating the need for third-party involvement. Previous attacks on smart contracts have already shown that existing vulnerabilities can lead to great financial losses. Yet, a study...

Smart contracts on Ethereum enable billions of dollars of value to be transacted in a decentralised, transparent and trustless environment. However, adversaries lie await in the Dark Forest, waiting to exploit any and all smart contract vulnerabilities in order to extract profits from unsuspecting victims in this new financial system. As the...

Within the context of the Ethereum blockchain protocol, reentrancy is a well-known and well-researched smart contract vulnerability. However, when considering GoQuorum, an Ethereum soft fork, barely any research discussing smart contract vulnerabilities exists. This report aims to partly fill this research gap by evaluating the reentrancy smart...

Blockchain networks have gained recent popularity among organisations that want to make use of the security aspects that blockchain provides. Fabric is one of the most used distributed network technologies, most commonly applied in scenarios that require confidential data to be stored securely and privately. Use case examples are finance,...
