Latitude and Topographical Dependence of Lightning Return Stroke Peak Current in Natural and Tower-Initiated Negative Ground Flashes

Farhad Rachidi-Haeri, Marcos Rubinstein

Experimental data show that the peak currents of first and subsequent lightning return strokes in negative ground flashes increase with decreasing latitude. In this paper, the reason for this dependence of peak return stroke current on latitude is explaine ...

Weight Erosion: An Update Aggregation Scheme for Personalized Collaborative Machine Learning

Martin Jaggi, Sai Praneeth Reddy Karimireddy, Mary-Anne Hartley, Felix Hans Michel Grimberg

Background. In medicine and other applications, the copying and sharing of data is impractical for a range of well-considered reasons. With federated learning (FL) techniques, machine learning models can be trained on data spread across several locations w ...

Mneme: A Mobile Distributed Ledger

Boi Faltings, Sujit Prakash Gujar

Advances in mobile computing have paved the way for new types of distributed applications that can be executed solely by mobile devices on device-to-device (D2D) ecosystems (e.g., crowdsensing). More sophisticated applications, like cryptocurrencies, need ...

The Learnability of the Grammar of Jazz: Bayesian Inference of Hierarchical Structures in Harmony

Daniel Harasim

Musical grammar describes a set of principles that are used to understand and interpret the structure of a piece according to a musical style. The main topic of this study is grammar induction for harmony --- the process of learning structural principles f ...

When and why performance goals predict exploitation behaviors: An achievement goal complex analysis of the selection function of assessment

David Nguyen, Fabrizio Butera, Hamza Sehaqui, Martin Jobin

We adopted an achievement goal complex framework (studying achievement goals and reasons connected to goals) to determine when and why performance goals predict exploitation of others' knowledge. We hypothesized that: (i) when selective assessment is used ...

Rate of change of frequency under line contingencies in high voltage electric power networks with uncertainties

Philippe René Joseph Jacquod, Melvyn Sandy Tyloo

In modern electric power networks with fast evolving operational conditions, assessing the impact of contingencies is becoming more and more crucial. Contingencies of interest can be roughly classified into nodal power disturbances and line faults. Despite ...

Water: its influence on the formation and crystallization of amorphous calcium carbonate

Huachuan Du

Nature produces CaCO3-based materials that display fascinating mechanical properties. These properties are a result of the exquisite control over the formation of CaCO3 crystals that nature possesses. Such a high level of control is likely achieved, at lea ...
