Prediction of the spacing and patterns of drying cracks in soils

Desiccation cracking of soils is of great importance to geotechnical and geoenvironmental engineering as it affects the soil physical integrity. Yet the mechanisms of drying cracking in soils, and the ways to control or avoid it, are still elusive. This pa ...

Site-Controlled InGaAs Quantum Dots with Tunable Emission Energy

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Marco Felici, Arun Mohan

Semiconductor quantum-dot (QD) systems offering perfect site control and tunable emission energy are essential for numerous nanophotonic device applications involving spatial and spectral matching of dots with optical cavities. Herein, the properties of or ...

Scaling and dynamics of washboard roads

Anne-Florence Raphaëlle Bitbol

Granular surfaces subjected to forces due to rolling wheels develop ripples above a critical speed. The resulting pattern, known as washboard or corrugated road, is common on dry unpaved roads. We investigated this phenomenon theoretically and experimental ...

Programming with Undo

Ersoy Bayramoglu

This thesis is about objects that can undo their state changes. Based on an earlier work on data structure persistence, we propose generating undo methods for classes from annotated classes automatically. As opposed to ephemeral data structures, persistent ...

Global Loss Evaluation Methods for Nonsinusoidally Fed Medium-Frequency Power Transformers

Alfred Rufer, Irma Villar

Medium-voltage conversion systems, such as traction and grid-connected converters, are continuously evolving toward higher power densities. Consequently, volume, weight, and material reductions are becoming major design issues, which lead the research focu ...

The effects of animations on verbal interaction in computer supported collaborative learning

Pierre Dillenbourg, Mirweis Sangin, Gaëlle Molinari

This paper focuses on the interaction patterns of learners studying in pairs who were provided with multimedia learning material. In a previous article, we reported that learning scores were higher for dyads of an ‘animations’ condition than for dyads of a ...

Porphyrin-based photocatalytic lithography

Jeffrey Alan Hubbell

Photocatalytic lithography couples light with photoreactive coated mask materials to pattern surface chemistry. We excite porphyrins to create radical species that photocatalytically oxidize, and thereby pattern, chemistries in the local vicinity. The tech ...

Noncoherent multi-source network coding

Christina Fragouli, Suhas Diggavi, Mahdi Jafari Siavoshani

We examine the problem of multiple sources transmitting information to one or more receivers that require the information from all the sources, over a network where the network nodes perform randomized network coding. We consider the noncoherent case, wher ...

Some Basic Functions for Tree Representations of Bayesian Markov Chain Monte Carlo Clustering

Anthony Christopher Davison, Vahid Partovi Nia

The paper contains description of the implementation of C code for tree representation of Markov Chain Monte Carlo(MCMC) clustering. The aim of the code is to produce results which helps in visual representation of the most frequent pattern, its agglomerat ...

A Conceptual View on Trajectories

Stefano Spaccapietra, Christine Parent, Christelle Vangenot, Maria Luisa Damiani, José Antonio Fernandes de Macedo

Analysis of trajectory data is the key to a growing number of applications aiming at global understanding and management of complex phenomena that involve moving objects (e.g. worldwide courier distribution, city traffic management, bird migration monitori ...
