Advancing ecohydrology in the 21st century: A convergence of opportunities

Andrea Rinaldo, Gabriel George Katul, Nicolaas Cornelis van de Giesen

Nature-based solutions for water-resource challenges require advances in the science of ecohydrology. Current understanding is limited by a shortage of observations and theories that can further our capability to synthesize complex processes across scales ...

Measurement-system design framework using multi-objective optimization for bridge load testing”

Ian Smith, Numa Joy Bertola

Due to conservative design models and safe construction practices, civil-infrastructure elements, such as bridges, usually have unknown amounts of reserve capacity that exceed code requirements. The quantification of this reserve capacity may lead to bette ...

Identification of Train Wheel Flat Accounting for Measurement and Modeling Uncertainties

Ian Smith, Numa Joy Bertola

In railway systems, wear-induced wheel flats (out-of-roundness wheel shape) are among the most common local surface defects. They reduce the train ride comfort, increase fatigue risk and raise safety concerns. A good knowledge of wheel flats (presence and ...

Elastomer-based pneumatic device to measure the mechanical properties of cell monolayers

Francesca Sorba

Everyday life physiological functions such as breathing, muscle contraction, and blood circulation rely on the ability of single cells to organize into higher complexity structures and sustain mechanical deformations. Cell monolayers are the simplest tissu ...

High-fidelity optical diffraction tomography of multiple scattering samples

Demetri Psaltis, Joowon Lim, Elizabeth Elena Antoine, Ahmed Ayoub

We propose an iterative reconstruction scheme for optical diffraction tomography that exploits the split-step nonparaxial (SSNP) method as the forward model in a learning tomography scheme. Compared with the beam propagation method (BPM) previously used in ...

Correction of surface error occurring in microlenses characterization performed by optical profilers

Toralf Scharf, Wilfried Noell, Jeremy Béguelin

Characterizing the surface of microlenses by optical profilers has the important advantages of measurement speed, flexibility and automation. Nevertheless, the accuracy of such characterization is limited by error occurring in non-flat measurements. Here, ...

Performance Assessment of Linearized OPF-based Distributed Real-time Predictive Control

Mario Paolone, Fabrizio Sossan

We consider the problem of controlling heteroge-neous controllable resources of a distribution network with the objective of achieving a certain power flow at the grid connection point while respecting local grid constraints. The problem is formulated as a ...

First measurement of the CKM angle phi(3) with B-+/--> D(K-S(0)pi(+)pi(-)pi(0)) K-+/- decays

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Sun Hee Kim, Donghyun Kim, Xiao Wang, Lei Li

We present the first model-independent measurement of the CKM unitarity triangle angle phi(3) using B-+/--> D(K-S(0)pi(+)pi(-)pi(0)) K-+/- decays, where D indicates either a D-0 or (D) over bar (0) meson. Measurements of the strong-phase difference of the ...

Lancet: A self-correcting Latency Measuring Tool

Edouard Bugnion, Evangelos Marios Kogias, Stephen Xin Mallon

We present LANCET, a self-correcting tool designed to measure the open-loop tail latency of µs-scale datacenter applications with high fan-in connection patterns. LANCET is self-correcting as it relies on online statistical tests to determine situations in ...
