In this thesis, the implementation of a passive, chipless, frequency coded RFID detection system for bedload transport studies is proposed. The proposed tag will be deployed in the semi-arid Río Colorado, Bolivia with the aim to develop quantitative sediment transport models that relate transport to grain size. Different algorithms are explored...

SeaState5 wants to facilitate the monitoring process for seabed cables of offshore wind farms. The company wants to achieve this by creating an unmanned vessel, named the Eagle, which can be analyzed from a remote location.<br/><br/>As students from TU Delft, we have been tasked to create a software framework that allows the Eagle to go to a...

60 million people around the world have epilepsy, which is a neurological disorder that severely impacts their day to day life negatively. Currently available methods to reduce the effects of epilepsy are either ineffective or require expensive and invasive surgery. A new method has been found that can suppress epilepsy without the need of...

In deze scriptie gaan we twee wiskundige objecten onderzoeken, het ultrafilter en de ultramacht. Zodra je in de wiskunde een nieuw object hebt bedacht zijn de eerste twee vragen die je stelt altijd 1) bestaat het? en 2) Als het bestaat, is het dan uniek, of zijn er meerdere? Nou is dat voor een ultrafilter relatief makkelijk te beantwoorden. In...

Deze thesis presenteert het ontwerp van een systeem dat de positie van zwemmers in water bepaalt. Het idee voor dit systeem is ontstaan binnen de vakgroep Wireless and Mobile Communications (WMC), onderdeel van de TU Delft. WMC ontwikkelde in 2007 een testopstelling voor driedimensionale positiebepaling die gebruik maakte van akoestische golven....

This thesis gives a thorough description of the mathematical tool called reflection positivity, which can be used to prove the occurrence of phase transitions in physical models. A major result, although already known, is a theorem that gives tractable conditions on the Hamiltonian such that the Boltzmann functional is reflection positive. In...

In this thesis, the implementation of a passive, chipless, frequency coded Radio-Frequency Identification (RFID) tag for bedload transport studies is proposed. The proposed tag will be deployed in the semi-arid Río Colorado river, Bolivia with the aim to develop quantitative sediment transport models that relate transport to grain size. The...

The quality of audio amplifiers used in Hi-Fi sound installations is largely determined by the distortion of the output signal. This report proposes a method of improving the distortion reduction in audio amplifiers by using a topology with active feedback. The characteristics of the standard non-inverting amplifier are extended to this new...

This thesis presents two submodules which are part of 'an FM Chirp Waveform Generator and Detector for Radar', namely the mixer and the modulator. The goal of this project is to design and simulate these submodules from an educational perspective. The modulator is implemented as a single-ended common-base Colpitts oscillator with modulation...

The salinity profile in a coastal sea-river system is the result of balancing of salt transport due to mixing of the water by tides and the freshwater discharge from the river. When for example during times of drought freshwater discharge suddenly declines, the salinity in the river may increase significantly and threaten drinking water supplies...

Deze thesis beschrijft de ontwerpkeuzes, het ontwerp en het begin van de implementatie van een sensorsysteem dat voor e12,50 aan componenten de waterdiepte, temperatuur en conductiviteit meet in waterputten. Aan de hand van de temperatuur en de conductiviteit kan de zoutconcentratie benaderd worden. Er is gekozen voor een combinatie van nieuwe...

Myopia is an eye disease that begins to develop at a young age, approximately between the ages of six and nine years. Children these ages spend a large amount of time inside school buildings. Two case studies have been studied to see what can be improved in school building design to get more light inside. Light measurements have been done to see...

The non-linear relation between Evapotranspiration (ET) and the atmospheric moisture demand in terms of vapor pressure deficit (VPD) has been widely reported. Observations point towards a diverse range of potential drivers; however, without uncovering why the identified factors are found to control diurnal ET-VPD hysteresis. Modelling efforts...

The work presented in this thesis investigates the creation of virtual sound sources in a room equipped with a limited number of loudspeakers. This limited number of loudspeakers is typical for consumer loudspeaker systems. Ideally, these systems can provide a listening experience in which localisation cues are completely present. However, in...

The goal of this thesis is to present a framework which can be used to optimize the observer and controller performance by placement of sensors and actuators on a continuous domain. The framework provides choices of model structure, cost functions and optimization methods to perform the placement. Systems which would be suitable for the use of...

Free competition in the insurance markets increases the competitiveness and lowers the premiums. If insurers lower their premiums without having a model that accurately quantifies the expected claim size, they can be in serious trouble. This research aims to accurately model the premiums and quantify the uncertainty involved using historic...

Technology developments are making it possible to start automating the last-mile of parcel logistics. This raises the question of how these autonomous technologies will interact with humans. The goal of this project is to design a concept of a delivery robot for DHL, that maximizes acceptance by pedestrians. <br/><br/>Literature research and...

According to a report published by the Dutch Safety Investigation Board in early September 2019, the safety of remotely controlled bridges is not su_cient (Onderzoeksraad voor de Veiligheid, 2019, pg.58). This report was published after the occurrence of two severe accidents in Zaandam, on the Den Uylbrug and the Prins Bernhardbrug. On both...

Historically, cities have played a major role in integrating newcomers into society. And in turn, many cities- including Amsterdam- have been shaped by migration. The conditions in neighborhoods in which many newcomers currently arrive do not offer the same flexibility. The graduation project proposes a strategy for the creation of inclusive...
