Latent Mechanisms of Polarization Switching from In Situ Electron Microscopy Observations

Vasiliki Tileli, Reinis Ignatans

In situ scanning transmission electron microscopy enables observation of the domain dynamics in ferroelectric materials as a function of externally applied bias and temperature. The resultant data sets contain a wealth of information on polarization switch ...

Large-scale traffic signal control and multimodal network design

Dimitrios Tsitsokas

Traffic congestion constitutes one of the most frequent, yet challenging, problems to address in the urban space. Caused by the concentration of population, whose mobility needs surpass the serving capacity of urban networks, congestion cannot be resolved ...

A fast algorithm to find reduced hyperplane unit cells and solve N-dimensional Bezout's identities

Cyril Cayron

Deformation twinning on a plane is a simple shear that transforms a unit cell attached to the plane into another unit cell equivalent by mirror symmetry or 180 degrees rotation. Thus, crystallographic models of twinning require the determination of the sho ...

Equipartition of Energy Defines the Size-Thickness Relationship in Liquid-Exfoliated Nanosheets

Nicola Marzari, Davide Campi

Liquid phase exfoliation is a commonly used method to produce 2D nanosheets from a range of layered crystals. However, such nanosheets display broad size and thickness distributions and correlations between area and thickness, issues that limit nanosheet a ...

Hydrophobic coating of mica by stearic acid vapor deposition

Juan José Segura Sugranes

We report on the preparation of thin films of stearic acid on mica by sublimation in air. We correlate their affinity to water (hydrophobic vs. hydrophilic character) to the morphology of the films as observed by Atomic Force Miscorcopy (AFM). Submonolayer ...

Complete intersections in rational homotopy theory

Kathryn Hess Bellwald

We investigate various homotopy invariant formulations of commutative algebra in the context of rational homotopy theory. The main subject is the complete intersection condition, where we show that a growth condition implies a structure theorem and that mo ...

Delay-Time Actuated Traffic Signal Control for an Isolated Intersection

This paper describes a new approach to control traffic signals at isolated intersections by capturing vehicles’ delay times and utilize them to adjust the green times. Similar to a traditional vehicle actuated control a queue clearing policy is applied: Wi ...

Adaptive Traffic Signal Control Using Vehicles’ Delay Times

This paper deals with a new approach to control traffic lights at isolated intersections. Delay times of vehicles are measured and utilized to adjust green times. The controlling scheme acts as follows: As soon as the accumulated delay times of vehicles on ...
