A Maximum-Likelihood-Based Two-User Receiver for LoRa Chirp Spread-Spectrum Modulation
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Orion Afisiadis, Joachim Tobias Tapparel, Mathieu Pierre Xhonneux
Long Range (LoRa) is an emerging low-power wide-area network technology offering long-range wireless connectivity to Internet of Things (IoT) devices. For energy efficiency reasons, LoRa end nodes implement a nonslotted ALOHA multiple access scheme to tran ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022A formula for the admittance of laterally excited bulk wave resonators (XBARs)
Luis Guillermo Villanueva Torrijo, Soumya Yandrapalli, Victor Plessky
The recently invented laterally excited bulk wave resonators (XBARs) demonstrate outstanding parameters suitable for the design of low loss filters for the fifth generation of mobile phones. The operation of XBARs can be interpreted as an excitation of ant ...
WILEY2021Local Vulnerabilities and Global Robustness of Coupled Dynamical Systems on Complex Networks
Coupled dynamical systems are omnipresent in everyday life. In general, interactions between
individual elements composing the system are captured by complex networks. The latter
greatly impact the way coupled systems are functioning and evolving in time. ...
EPFL2020Dispatching Stochastic Heterogeneous Resources Accounting for Grid and Battery Losses
Jean-Yves Le Boudec, Mario Paolone, Fabrizio Sossan, Lorenzo Enrique Reyes Chamorro, Eleni Stai
We compute an optimal day-ahead dispatch plan for distribution networks with stochastic resources and batteries, while accounting for grid and battery losses. We formulate and solve a scenario-based AC Optimal Power Flow (OPF), which is by construction non ...
2018Diamond Configuration for Non-Reciprocal Transmission
A system scheme is presented, which allows non-reciprocal wave transmission or directional amplification of electromagnetic signals, using a boxed four-node method. Edges represent strong hopping interactions and diagonals stand for weak parametric interac ...
Ieee-Inst Electrical Electronics Engineers Inc2017The strength and dislocation microstructure evolution in superalloy microcrystals
In this work, the evolution of the dislocations microstructure in single crystal two-phase superalloy microcrystals under monotonic loading has been studied using the three-dimensional discrete dislocation dynamics (DDD) method. The DDD framework has been ...
Elsevier2017Radiation and Internal Loss Engineering of High-Stress Silicon Nitride Nanobeams
Dalziel Joseph Wilson, Amir Hossein Ghadimi
High-stress Si3N4 nanoresonators have become an attractive choice for electro- and optomechanical devices. Membrane resonators can achieve quality factor (Q)frequency (f) products exceeding 10(13) Hz, enabling (in principle) quantum coherent operation at r ...
Amer Chemical Soc2017Modelling of Mechanical Interaction in Piezoelectric Actuated Resonant System
Automatic assembly system has been continuously drawing attention since the beginning of the 20th century. Parts feeding system is one of the important subsystems. The parts feeding system is used for delivering bulk parts into separated individual parts. ...
EPFL2016Dissipation engineering of high-stress silicon nitride nanobeams
Tobias Kippenberg, Dalziel Joseph Wilson, Amir Hossein Ghadimi
High-stress SiN nanoresonators have become an attractive choice for electro- and optomechanical devices. Membrane resonators can achieve quality factor () - frequency () products exceeding Hz, enabling (in principle) quantum coheren ...
2016Global Ill-Posedness of the Isentropic System of Gas Dynamics
Elisabetta Chiodaroli, Camillo De Lellis
We consider the isentropic compressible Euler system in 2 space dimensions with pressure law p () = (2) and we show the existence of classical Riemann data, i.e. pure jump discontinuities across a line, for which there are infinitely many admissible bounde ...
