The flow field induced by a flat plate aerofoil with simulated battle damage

This investigation looks into the induced surface pressure field and flow field of a 2-D flat plate aerofoil with simulated battle damage. Enhancing survivability is a major design criteria for military aircraft designers, and the aerodynamic effects of battle damage has recently come to the fore as an area that warrants further attention. The current investigation is in effect a continuation of the battle damage research initiated at Loughborough University by Irwin, with the ultimate aim of enabling quick and accurate CFD studies to assess the aerodynamic impact of battle damage on a lifting surface.

Dynamically generated dimension reduction and crossover in a spin orbital model

We study a spin orbital model in which the spin-spin interaction couples linearly to the orbital isospin. Fluctuations drive the transition from paramagnetic state to C type ordered state into a strongly first order one, as observed in $V_2O_3$. At T=0, there is a FOCS to FOGS transition. Close to the transition point, the system shows dynamically generated dimension reduction and crossover, resulting in one or more spin reentrant transitions.Comment: Submitted to PRL. 4 pages and one figur

Desenvolvimento de um sistema de monitoramento remoto de umidade do solo.

Este trabalho tem por objetivo apresentar o protótipo de um sistema autônomo de monitoramento de umidade do solo. O sistema consiste de três sensores de umidade de solo conectados a um microcontrolador Arduino, alimentado por uma bateria carregada por uma célula fotovoltaica. O propósito desse sistema é realizar a transmissão por módulo Xbee® de sinal analógico referente ao teor de umidade do solo. O sinal transmitido é captado por outro módulo Xbee® ligado a um programa servidor capaz de armazenar continuamente as informações captadas
