Examining the Effects of Privacy-Aware Blended Learning Scenarios in Executive Training for Policymakers and Government Officials

Denis Gillet, Juan Carlos Farah, Isabelle Barbara Marie-Hélène Cardia

Enabling blended learning scenarios that foster participation and interaction is an important consideration in the design of executive training programs. To investigate this design process, our study focuses on two aspects that are present in such scenario ...

Regional variation in the rural-urban fertility gradient in the developing world

Mathias Lerch

The study of regional trends in the rural-urban fertility gradient helps us to understand the pace of completion of the fertility transition and the geography of urban growth in the global South. We question whether the hypothesized inverted U-shaped evolu ...

Transport à câble aérien en milieu urbain: pertinence et pratique

Fernando Anisio De Oliveira Simas

The intense urbanization of cities has left few options when it comes to insert large mobility infrastructure they need to move their inhabitants. A surface rail network, a dedicated roadway bus line or any other mobility infrastructure such as a tramway a ...

GeoFarmer: A monitoring and feedback system for agricultural development projects

Claudia Rebeca Binder Signer

Farmers can manage their crops and farms better if they can communicate their experiences, both positive and negative, with each other and with experts. Digital agriculture using internet communication technology (ICT) may facilitate the sharing of experie ...

Response of thin lightly-reinforced concrete walls under cyclic loading

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida

During the last two decades, thin concrete walls have been frequently used to brace mid- to high-rise buildings in some Latin American countries. This structural system differs significantly in terms of wall geometry and reinforcement layout from tradition ...

iNVESTIGA: Connecting the Colombian Scientific Diaspora with Secondary Schools in Colombia

Rafael Eduardo Carrillo Rangel, Ricardo Alberto Corredor Jerez

According to recent studies, Latin America is the region with the highest emigration rate in the world, specially affecting the highly educated population. One of the consequences of this process is the expansion of business and scientific diasporas. Colom ...

Prosperity and Social Inequalities: Montes Claros, How to Plan an Intermediary City in Brazil

Jean-Claude Bolay

According to international statistics, nearly 50% of the world’s urban population live nowadays in cities of less than 500,000 inhabitants. These small and medium-sized cities play a role of intermediation between rural regions, local economy and more exte ...

L'espace public à Bogotá : entre les enjeux de la mobilité et la fragmentation urbaine

Yafiza Zorro Maldonado

There is a link between phenomena covered by the umbrella term «urban mobility» and the wealth of social and spatial dynamics active in de-structuring the city as a coherent spatial model, a process known as «urban fragmentation». It is therefore reasonabl ...

Sustainability assessment of an urban neighborhood revitalization project in Bogotá by transposition of European indicator systems to the Colombian context

Emmanuel Rey, Sophie Lufkin

With 80% of its population living in cities, Latin America is one of the most urbanized regions in the planet. Its urban areas are characterized by rapid transformations that entail urban sprawl and the subsequent environmental impacts, social segregation ...

Imaging blood cells through scattering biological tissue using speckle scanning microscopy

Demetri Psaltis, Ye Pu, Ye Pu, Xin Yang

We demonstrate imaging of blood cells enclosed in chicken skin tissue using speckle scanning microscopy (SSM). Clear images of multiple cells were obtained with subcellular resolution and good image fidelity, provided that the object dimension was smaller ...

Bandwidth and repetition rate programmable Nyquist sinc-shaped pulse train source based on intensity modulators and four-wave mixing

Camille Sophie Brès, Mohammad Amin Shoaie, Armand Vedadi-Comte, Steevy Joyce Cordette

We propose and experimentally demonstrate an all-optical Nyquist sinc-shaped pulse train source based on intensity modulation and four-wave mixing. The proposed scheme allows for the tunability of the bandwidth and the full flexibility of the repetition ra ...

Monte Carlo simulation of the field back-scattered from rough surfaces

Christian Depeursinge, Stéphane Chamot

A novel approach for the simulation of the field back-scattered from a rough surface is presented. It takes into account polarization and multiple scattering events on the surface, as well as diffraction effects. The validity and usefulness of this simulat ...

Inline holographic coherent anti-Stokes Raman microscopy

Ho Ling Li, Demetri Psaltis

We demonstrate a simple approach for inline holographic coherent anti-Stokes Raman scattering (CARS) microscopy, in which a layer of uniform nonlinear medium is placed in front of a specimen to be imaged. The reference wave created by four-wave mixing in t ...

Speckle statistics in optical coherence tomography

Theo Lasser, Boris Clément Karamata, Markus Laubscher, Kai Hassler

The two previously reported calculations of the amplitude distribution of speckles in optical coherence tomography, each based on a different mathematical formulation, yield different results. We show that a modification of an initial assumption in one of ...
