TAKEN: Experimental evaluation of unsupervised indoor localization

Past Projects

Contact: Dümbgen, Frederike, Sepand Kashani Synopsis: Experimental evaluation of unsupervised indoor localization. Level: Summer internship or BS/MS project Description: Due to their aptitude in depicting complex dependencies, neural networks are a promising candidate for indoor localization. Omnipresent phenomena such as multi-path signal propagation, shadowing and device noise introduce high noise in distances inferred from radio (…)

Beamforming of Light Waves for μ-scale Manufacturing

Past Projects

  Advisors: Matthieu Simeoni (LCAV), Sepand Kashani (LCAV) and Julien Gateau (GALATEA, Microcity)   Contact: Matthieu Simeoni ([email protected])   Synopsis: Assess novel beamforming solutions for light waves using a spatial light modulator.    Levels: Bachelor, Master (, including Master thesis)    Sections: MT, IC, PH, EL   Description: Lasers are often used for carving materials (…)

A Spline Approximation Framework for Spatio-Temporal Environmental Monitoring

Past Projects

  Main Advisors: Matthieu Simeoni and Julien Fageot Synopsis: Develop a spline approximation framework for spatio-temporal environmental monitoring at global scales. Level: Bachelor/Master (including Master Thesis). Description: One aid towards addressing the current environmental crisis consists in building a “digital twin” of the Earth. The latter would take the form of an exhaustive computer simulation relying on past and (…)

Periodic Splines and their Applications to Approximation Theory

Past Projects

Advisors: Matthieu Simeoni and Julien Fageot Synopsis: Obtain innovative results and methods for the approximation of periodic functions with periodic splines. Level: Master/Bachelor. Description: A spline is a piecewise-smooth function used in approximation theory, known to be an excellent tool for bridging the discrete and continuous setting. As such, it is therefore at the core of many (…)

Open-source hardware and GUI design for a blind drone

Past Projects

Contact: Dümbgen, Frederike Synopsis: Design a PCB and user interface for a Crazyflie drone to process acoustic and RF signals. Level: BS, MS Description: The Crazyflie (https://www.bitcraze.io/crazyflie-2-1/ ) is a developer-friendly, open-source drone solution. It comes with a customizable python client (including GUI), and open-source firmware which is readily extendable. In this semester project, we (…)

Learning acoustics-based localization of a blind drone

Past Projects

Contact: Dümbgen, Frederike Synopsis: Study and test drone’s capability to localize itself from acoustic signals. Level: BS, MS Description: Acoustic signals are inexpensive to create and record and their physics are well understood. Using only relatively cheap and light hardware, drones could therefore be equipped with audio processing capabilities. However, very few drone localization systems (…)

Learning multi-modal localization

Past Projects

Contact: Dümbgen, Frederike Synopsis: Development of a learning-based framework for indoor localization using different modalities. Level: MS Description: Due to their aptitude in depicting complex dependencies, neural networks are a promising candidate for indoor localization. Omnipresent phenomena such as multi-path signal propagation, shadowing and device noise introduce non-linear effects in the data, and make conventional (…)

Application to view hyperspectral images

Past Projects

Advisors: Latty, Arnaud ; Scholefield, Adam James Synopsis: Level: BS, MS Description: The audiovisual communications laboratory (www.epfl.ch/labs/lcav) is looking for a student for the development of an application to view hyperspectral images, as part of a semester project. While the project will be software based, it has connections with many topics like sampling theory, hardware (…)

lego structure with multiple microphones

Multichannel DoA Estimation

Past Projects

Advisor: Dalia El Badawy Description: Recent work has shown that it is possible to estimate the direction of arrival (DoA) of a sound using just one microphone, albeit a special one surrounded by LEGO bricks [1]. The idea is that the LEGO scatters the incident sound providing a special directional signature that we can use to estimate (…)

Circuit design for bio-inspired sampling

Past Projects

Contact: Adam, Karen Synopsis: Biologically inspired A/D conversion Level: BS/MS Description: Sampling is a key step in converting any analogue signal to the digital world. Usually, it is done by recording the signal’s amplitude at certain predefined time points. In nature, sampling is done differently. A neuron integrates its input until a threshold is reached (…)
