Efeito do Lodo de Esgoto na Indução de Supressividade in vitro a Phytophthora nicotianae*

Effect of sewage sludge in vitro to suppress Phytophthora nicotianae Soil organic matter amendments may provide an alternative management practice for soil diseases caused by Phytophthora spp. In this paper we have evaluated the effectiveness of residential sewage sludge to suppress P. nicotianae under laboratory conditions. The effect of sewage sludge on P. nicotianae survival was evaluated by...

Efeito do entrelaçador na comparação de desempenho de sistemas OFDM e SCCP

This article establishes a performance comparison between the OFDM (Orthogonal Frequency Division Multiplexing) and the SCCP (Single Carrier with Cyclic Prefix) systems from the interleaver point of view. Some interleavers schemes are analyzed in a block fading channel scenario, as well as in the context of deep fade static channels. Keywords— OFDM, SCCP, interleaving, frequency selective chann...

Modelagem Espacial de Florestas Estacionais do Domínio do Cerrado no Estado de Minas Gerais

The general objective of this work is to map the potential distribution of seasonal forest of Cerrado in Minas Gerais, Brazil, through the species distribution modeling of its indicative species. Occurrence data and list of species of the areas were recovered in the database TreeAtlan 1.0. The environmental datasets used for the work involved climatic coverings related with temperature and prec...

Snake-3D na Modelagem Tridimensional e Medição do Comprimento de Arcos Elétricos

It is proposed a novel approach based on a three-dimensional active contour (3D-snake), for the tracking and measurement of the length of artificially generated electrical arcs captured by a calibrated pair of cameras. The 3D-snake is represented by a B-spline which evolves in 3D space constrained by internal and external forces. The external forces come from pairs of images of the arc in evolu...
