Simulation of the Dutch electricity system: A software expansion for the Illuminator

The aim of this report is to discuss the design of the software that creates a simulation for the national electricity grid level of the Netherlands. This is done by further developing the open-source energy system integration development kit called the Illuminator. Where the goal of this software is to create an extra case, add a Graphical User...

Circularity in Railway: How circularity can be applied in railway

Multimodal learning analytics on sustained attention by measuring ambient noise

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...

Camera-based face and infrared temperature sensing of learner's affective state in the remote learning context using machine learning

Remote learning, learning from home using online available materials, is becoming increasingly more common. This paper focuses on reading activities during remote learning. An important part of learning is keeping sustained attention on the learning materials, as a shift from sustained attention to internal thought or mind-wandering oftentimes...

DC Grid Design: Distribution of the electricity grid of a tiny house com­munity

This thesis covers the top­level design of a DC microgrid of a tiny house community on the roof ofa high­rise building in Rotterdam. This DC microgrid consists of 12 tiny houses, a common usagearea, Renewable Energy Supply (RES) methods, using solar and wind energy, and an Energy Storagesystem (ESS). This design is part of a complete DC smart...

Solar Powered Weather Station: Sensors and Control

Increasing concerns surrounding the influence of urban climate on the livability of cities and the health of citizens lead to a need for environmental data on a more localized scale. Self-powered weather stations that use the many WiFi networks spanning the city to transmit their data are a promising solution to increase the amount of data on...

Autonomous Temperature Sensor for Smart Agriculture: Energy Harvesting and Control

Many countries in the world face the problem of fruit frost during spring, which results in the loss of harvested crops. Solutions exist to prevent the fruit to freeze, however this requires that the temperature is known. Therefore, a smart autonomous temperature sensor network is designed that is capable of acquiring a 3D temperature profile of...

The role of dockless shared-bikes in Delft: From a user perspective

This thesis provides an insight into the role of dockless shared-bikes (Mobike) in Delft. The objective of is to fill the knowledge gap about the users of shared-bicycles and their motivations to use shared-bikes in Delft. A survey is and finally gained 91 useful results. 76% of respondents are students, and in general, people are highly...

Development of Power System Control for the DeciZebro

The development of swarm robotics strives for resilience, a key factor in this is energy supply. Without energy a robot swarm cannot operate, so a self sustaining power management system is of great importance. In this thesis, the design of the power management system control hardware and firmware for the new DeciZebro is discussed. The power...

Simulation of the effect of atmospheric stratification on the power production of a wind farm

The wind energy industry is growing more than ever before and wind energy as a renewable energy source has shown quite a potential over the years. Unfortunately, the power yield of a wind farm can fluctuate largely over time, which originates from fluctuating wind speed magnitudes. Convection of air, turbulence, humidity and radiation of heat are...

AR for Sustainable Renovation of Buildings

Energiepaleis, a company that realizes sustainable home renovations, requested an application that uses augmented reality to show their customers beforehand, what certain sustainable devices would look like in their homes after renovations. A marker is placed on the spot where the device needs to stand and then the application will show the...

A Smart Home: Main Control Unit and Nodes

In order to cope with various supplies and loads in an autonomous microgrid, a system of sensors and a control unit was developed. The goals of this system are to cope efficiently in the event of an energy supply shortage, and to prevent such events as much as possible. To achieve these goals, the aim was to manage energy in the system as...
