Improved analysis of a max-cut algorithm based on spectral partitioning
(SIAM, 2015)
Trevisan [SIAM J. Comput., 41 (2012), pp. 1769-1786] presented an algorithm for Max-Cut based on spectral partitioning techniques. This is the first algorithm for Max-Cut with an approximation guarantee strictly larger ...
Estudo da resposta espectral de alvos urbanos com espectroscopia de reflectância e imagens de alta resolução espacial
(Universidade Federal de Santa MariaBrasilGeografiaUFSMPrograma de Pós-Graduação em GeografiaCentro de Ciências Naturais e Exatas, 2014-12-10)
Urban areas are composed with diverse set of materials arranged in a complex way
by man for its survival. Remote sensing is the tool with potential for obtain spectral
data of urban materials and their conditions. This ...
A double demodulation algorithm for narrow spectral features
(Instituto Geofísico del Perú, 1995)
This paper proposes a technique for processing signals in which the relevant feature consists of the shape and position of narrow doppler spectral lines. The proposed technique is the digital version of a quadrature ...
Spectral Graph Analysis for Process Monitoring
(American Chemical Society, 2014-05)
Process monitoring is a fundamental task to support operator decisions under ab- normal situations. Most process monitoring approaches, such as Principal Components Analysis and Locality Preserving Projections, are based ...
Improvement of leaf nitrogen content inference in Valencia-orange trees applying spectral analysis algorithms in UAV mounted-sensor images
(Elsevier B.V., 2019-11-01)
Nitrogen is one of the main required nutrients for the production of citrus plants. Farmers have used the chemical analysis of leaf tissue to determine the amount of nitrogen needed in a crop. However, its possible to ...

SPECTRAL ANALYSIS OF TIME CHANGES OF HOROCYCLE FLOWS
(AMER INST MATHEMATICAL SCIENCES-AIMS, 2012)
We prove (under the condition of A. G. Kushnirenko) that all time changes of the horocycle flow have purely absolutely continuous spectrum in the orthocomplement of the constant functions. This provides an answer to a ...
