Geometric rectification for nanoscale vibrational energy harvesting
(American Physical Society, 2018-02)
In this work, we present a mechanism that, based on quantum-mechanical principles, allows one to recover kinetic energy at the nanoscale. Our premise is that very small mechanical excitations, such as those arising from ...
Similaridade geometrica de bacias hidrograficas e o mapeamento de solos.
(1985-12-01)
The following soil classes were identified in the studied area: Quartz Sands (AQ), Yellow Red Podzolic, Dusky Red Latosol (LR), 'Terra Roxa estruturada' (TE), Lithosol substrate sandstone (Lia) and Hidromorphic (Hi). The ...

Sexual dimorphism in a freshwater atyid shrimp (Decapoda: Caridea) with direct development: A geometric morphometrics approach
(Magnolia Press, 2016-11)
Neocaridina davidi is a caridean shrimp that has gained popularity in recent years as an ornamental species. Using geometric morphometrics, we investigated sexual dimorphism in carapace and second abdominal segment shape ...
Predicting the behaviour of structures under impact loads using geometrically distorted scaled models
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
When a scaled structure (model or replica) is used to predict the response of a full-size compound (prototype), the model geometric dimensions should relate to the corresponding prototype dimensions by a single scaling ...
Soliton Almost Kähler Structures on 6-Dimensional Nilmanifolds for the Symplectic Curvature Flow
(Springer, 2015-10)
The aim of this paper is to study self-similar solutions to the symplectic curvature flow on 6-dimensional nilmanifolds. For this purpose, we focus our attention on the family of symplectic two- and three-step nilpotent ...
Ensinando e aprendendo geometria: uma experiência com o software Cabri-Géomètre II na 5a série do ensino fundamental.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Educação - PPGE, 2003-08-27)
In the last three decades, geometry teaching in Brazil has had serious problems. A number of Brazilian researchers have identified the cause of such problems and proposed ways likely to overcome this chaotic scenario.
