Demand-based operations of vehicle sharing systems
Vehicle sharing systems (VSSs) allow users to rent vehicles for a short period of time, in a more flexible and convenient manner compared to the traditional vehicle rental services. The long-term VSS subscription replaces the need for contract signing for ...
EPFL2023DatAFLow: Toward a Data-Flow-Guided Fuzzer
Coverage-guided greybox fuzzers rely on control-flow coverage feedback to explore a target program and uncover bugs. Compared to control-flow coverage, data-flow coverage offers a more fine-grained approximation of program behavior. Data-flow coverage capt ...
2023Modeling and mitigating supply chain disruptions as a bilevel network flow problem
Anna Timonina-Farkas, René Yves Glogg
Years of globalization, outsourcing and cost cutting have increased supply chain vulnerability calling for more effective risk mitigation strategies. In our research, we analyze supply chain disruptions in a production setting. Using a bilevel optimization ...
SPRINGER HEIDELBERG2022Optimal Matching of Random Parts
This paper examines the minimization of the cost for an expected random production output, given an assembly of finished goods from two random inputs, matched in two categories. We describe the optimal input portfolio, first using the standard normal appro ...

The organic small molecule 4,4',4",4"'-(5,5-dimethoxycyclopenta-1,3-diene-1,2,3,4-tetrayl)tetrakis(N,N-bis(4-methoxyhenyl)aniline (CPDA 1), shows electrochemical properties very close to spiro-OMeTAD indicating a high compatibility with PSC systems for its ...
2022Exergy and exergoeconomic analyses of sustainable furfural production via reactive distillation
Lignocellulosic biomass is a potential renewable resource for production of high-value, sustainable products. Furfural is among the important bio-based chemicals in biorefineries. However, the conventional process of furfural production using a reaction-se ...

Giuseppe Carleo, Julien Sebastian Gacon, Stefan Woerner
The Quantum Fisher Information matrix (QFIM) is a central metric in promising algorithms, such as Quantum Natural Gradient Descent and Variational Quantum Imaginary Time Evolution. Computing the full QFIM for a model with d parameters, however, is computat ...
VEREIN FORDERUNG OPEN ACCESS PUBLIZIERENS QUANTENWISSENSCHAF2021Modeling Supply Chain Disruptions: A Network Flow Approach
Globalization, outsourcing and cost optimization have all contributed to increased supply chain vulnerability, yet our understanding of effective mitigation strategies remains limited. In our research, we study the effects of disruptions on supply chain ne ...
EPFL2021Advances and Open Problems in Federated Learning
Martin Jaggi, Sebastian Urban Stich, Lie He, Yang Liu, Ayfer Özgür Aydin, Florian Tramèr, Qiang Yang, Ananda Theertha Suresh, Badih Ghazi
Federated learning (FL) is a machine learning setting where many clients (e.g., mobile devices or whole organizations) collaboratively train a model under the orchestration of a central server (e.g., service provider), while keeping the training data decen ...
NOW PUBLISHERS INC2021Nothing is lost, nothing is created, everything is reused: structural design for a circular economy
Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting
Structural designers’ efforts to reduce environmental impacts traditionally consist of developing systems that minimise material quantities or use low-impact materials. A third strategy is currently (re)emerging: the reuse of structural components over mul ...
