Redes sociais e sistema de informação no meio rural.
Este artigo tem por objetivo apresentar e discutir ambientes interativos de comunicação que são construídos no meio rural e a importância de se mensurar tais processos como subsídio à gestão de conteúdos e tomada de decisão. Apresenta como indicativo o sistema de informação e conhecimento tecnológico da cadeia produtiva do arroz no Mato Grosso. Buscou-se contribuir sobre a importância da pesquisa em comunicação como pré-requisito fundamental de interação social que abastece os diversos meios e redes sociais, midiáticas ou não. Observou-se nesta pesquisa que as inter-relações que são visualizadas entre os atores responsáveis por uma série de processos que incluem a produção, transformação, distribuição e consumo possibilitam avaliar a forma de participação nas mídias sociais e demais segmentos de uma determinada cadeia
Cenários da comunicação e novas tecnologias de informação em centro de pesquisa.
A ciência, a tecnologia, a globalização e a sociedade da informação e da comunicação empurram os países, principalmente em fase de desenvolvimento, a terem que enfrentar em um curto espaço de tempo ajustes tecnológicos, políticos, econômicos e educacionais dentro de perspectivas cada vez mais transitórias e mutáveis no cenário atual.bitstream/item/29513/1/hag.pd
Analysis of the velocity field of granular hopper flow
We report the analysis of radial characteristics of the flow of granular
material through a conical hopper. The discharge is simulated for various
orifice sizes and hopper opening angles. Velocity profiles are measured along
two radial lines from the hopper cone vertex: along the main axis of the cone
and along its wall. An approximate power law dependence on the distance from
the orifice is observed for both profiles, although differences between them
can be noted. In order to quantify these differences, we propose a Local Mass
Flow index that is a promising tool in the direction of a more reliable
classification of the flow regimes in hoppers
Seismic vulnerability of churches in Faial and Pico islands, Azores
Earthquakes represent one of the main cause of serious damage and loss of historic and architectural heritage. Interventions to preserve these building should start with a careful knowledge and assessment of their seismic vulnerability, in order to support any needed retrofitting and strengthening measures.
This paper proposes a procedure to register and diagnose of the level of damage on churches after the occurrence of an earthquake, and also to assess the seismic vulnerability of this type of construction. This procedure was applied to sixteen churches in the Azores islands which were hit by the July 9th 1998 earthquake.
Belfries of church towers are elements with a particular seismic vulnerability. For this reason, and based on the Italian methodology proposed by the Linee Guida (2006), it is applied to belfries of two churches from Pico (Azores), a simplified mechanical model for assessment of seismic vulnerability of this type of structures
Quantum Critical Point in the Spin Glass-Kondo Transition in Heavy Fermion Systems
The Kondo-Spin Glass competition is studied in a theoretical model of a Kondo
lattice with an intra-site Kondo type exchange interaction treated within the
mean field approximation, an inter-site quantum Ising exchange interaction with
random couplings among localized spins and an additional transverse field in
the x direction, which represents a simple quantum mechanism of spin flipping.
We obtain two second order transition lines from the spin-glass state to the
paramagnetic one and then to the Kondo state. For a reasonable set of the
different parameters, the two second order transition lines do not intersect
and end in two distinct QCP.Comment: 20 pages; 1 figure; to appear in Physical Review
Classical and quantum coupled oscillators: symplectic structure
We consider a set of N linearly coupled harmonic oscillators and show that
the diagonalization of this problem can be put in geometrical terms. The matrix
techniques developed here allowed for solutions in both the classical and
quantum regimes.Comment: 27 pages, 6 figure
