Constraining the Ephemeris and Interior Structure of Io using Space-Based Astrometry by JUICE

Owing to the assumed presence of sub-surface oceans, the Galilean satellites - Io, Europa, Ganymede, and Callisto - are among the most promising candidates for potential extraterrestrial habitats within our Solar System. To this end, the moons are going to be extensively studied by the upcoming JUICE and Europa Clipper missions. Ultimately,...

Application of Deep Neural Networks to the Operator Space of Nonlinear PDE for Physics-Based Proxy Modelling

In this study, we utilize deep neural networks to approximate operators of a nonlinear partial differential equation (PDE), within the Operator-Based Linearization (OBL) simulation framework, and discover the physical space for a physics-based proxy model with reduced degrees of freedom. In our methodology, observations from a high-fidelity...

SPAD-based Light Detection and Ranging for 3D imaging: Receiver operation and in-pixel TDC design for automotive application

In this work, a SPAD-based LiDAR system is studied. In particular, the system employs a direct time-of-flight (dToF) method to reconstruct a target-reflected pulses using histogram, from which the distance to the target is estimated. More particularly, a time correlated single photon counting (TCSPC) method has been used to record the flight...

Of straw figures and multi-stakeholder monitoring: a response to Willem Schinkel

This article is a response to Willem Schinkel’s provocation piece. While mostly agreeing with Schinkel, my response questions Schinkel’s commitment to losing immigrant integration as an object of analysis. I point to the integrationist logic with which Schinkel assaults superdiversity, to more broadly question how prescriptive a social science...

The Mental Island

The Mental Island project is a new public realm which is proposed for the city of Genoa. As the contemporary city reveals a fluid system where everything is trapped in it. The Mental Island becomes the other side of the city for citizens to escape from the hybrid conditions. By mental isolation, the lodging units on the island offer a space for...

The Lobby Lobby

This project lobbies for the lobby, as a generous space in corporate cities capable of reversing the trend of atomization. Originating in capitalistic societies, lobbies are oddly socialistic entrances to mundane, stratified private spaces above. Formed in the gap between the ground and a hovering tower, the lobby is a distinctly modern type,...

A 60 GHz Frequency Generator Based on a 20 GHz Oscillator and an Implicit Multiplier

This paper proposes a mm-wave frequency generation technique that improves its phase noise (PN) performance and power efficiency. The main idea is that a fundamental 20 GHz signal and its sufficiently strong third harmonic at 60 GHz are generated simultaneously in a single oscillator. The desired 60 GHz local oscillator (LO) signal is delivered...

Analysis and Design of a Multi-Core Oscillator for Ultra-Low Phase Noise

In this paper, we exploit an idea of coupling multiple oscillators to reduce phase noise (PN) to beyond the limit of what has been practically achievable so far in a bulk CMOS technology. We then apply it to demonstrate for the first time an RF oscillator that meets the most stringent PN requirements of cellular basestation receivers while...

Smart temperature sensors in standard CMOS

A smart temperature sensor is an integrated system consisting of a temperature sensor, its bias circuitry and an analog-to-digital converter (ADC). When manufactured in CMOS technology, such sensors have found widespread use due to their low cost, small size and ease of use. In this paper the basic operating principles of CMOS smart temperature...

Design and Fabrication of On-Chip Cooing Devices Based on the Peltier Effect

The aim of this thesis project is to design and fabricate a high efficiency on chip cooling device based on the Peltier effect. Bismuth telluride (Bi2Te3) and antimony telluride (Sb2Te3) are employed to form thermocouple for their high Seebeck coefficient and high figure of merit. The models of the devices are simulated in the software program...
