Parallel laser micromachining based on diffractive optical elements with dispersion compensated femtosecond pulses
Optical Society of America (2013)We experimentally demonstrate multi-beam high spatial resolution laser micromachining with femtosecond pulses. The effects of chromatic aberrations as well as pulse stretching on the material processed due to diffraction ... -
Spectral–Spatial Pixel Characterization Using Gabor Filters for Hyperspectral Image Classification
Institute of Electrical and Electronics Engineers (IEEE) (2013)This paper presents a spectral-spatial pixel characterization method for hyperspectral images. The characterization is based on textural features obtained using Gabor filters over a selected set of spectral bands. This ... -
Diffractive digital lensless holographic microscopy with fine spectral tuning
Optical Society of America (2013)We experimentally demonstrate an all-diffractive optical setup for digital lensless holographic microscopy with easy wavelength line selection and micrometric resolution. In the proposed system, an ultrashort laser pulse ... -
Reply to Townsend et al.: Decoupling contributions from canopy structure and leaf optics is critical for remote sensing leaf biochemistry (Letter)
National Academy of Sciences (2013)Townsend et al. (1) agree that we explain the observed relationship (2) between foliar nitrogen (%N) and near-infrared (NIR) canopy reflectance is largely due to structure - i.e., structural variation due to fraction of ... -
Femtosecond filamentation in sapphire with diffractive lenses
Optical Society of America (2013)In this paper, we demonstrate novel properties in the phenomenology of supercontinuum generation in sapphire with diffractive lenses and provide a complete spatial, spectral, and temporal characterization of the so-generated ... -
Percentage Points of a Test Statistic Useful in Manova with Structured Covariance Matrices
Nova Science Publishers (2013)The exact distribution of a test statistic ΛH for testing equality of mean vectors of m p-variate Gaussian populations having compound symmetry has been derived using inverse Mellin transform, calculus of residues and ... -
Shape description from generalized support functions
Elsevier (2013)The generalized support function is considered to be a representation of shape properties of compact connected sets in R2. Some interesting properties are studied and several parameters are defined for use in shape description ... -
Enhancing integrated environmental modelling by designing resource-oriented interfaces
Elsevier (2013)Integrated environmental modelling is gaining momentum for addressing grand scientific challenges such as monitoring the environment for change detection and forecasting environmental conditions along with the consequences ... -
Extrinsic isoperimetry and compactification of minimal surfaces in Euclidean and hyperbolic spaces
© Springer, Part of Springer Science+Business Media (2013)We study the topology of (properly) immersed complete minimal surfaces P 2 in Hyperbolic and Euclidean spaces which have finite total extrinsic curvature, using some isoperimetric inequalities satisfied by the extrinsic ... -
Dispersion management in two-photon microscopy by using diffractive optical elements
Optical Society of America (2013)We demonstrate efficient generation of wide-field fluorescence signals in two-photon microscopy exploiting diffractive optical elements and short pulses by using a dispersion-compensated beam delivery optics module. ... -
Geospatial information infrastructures to address spatial needs in health: Collaboration, challenges and opportunities
Elsevier (2013)Most health-related issues such as public health outbreaks and epidemiological threats are better understood from a spatial–temporal perspective and, clearly demand related geospatial datasets and services so that decision ... -
The Euler Number from the Distance Function
International Society for Stereology (2013)We present a new method to obtain the Euler number of a domain based on the tangent counts of concentric spheres in R3 (or circles in R2), with respect to the center O, that sweeps the domain. This method is derived from ... -
Spatial pattern modelling of wildfires in Catalonia, Spain 2004–2008
Elsevier (2013)The paper has three objectives: firstly, to evaluate how the extent of clustering in wildfires differs across the years they occurred; secondly, to analyse the influence of covariates on trends in the intensity of wildfire ... -
A literature review on the application of evolutionary computing to credit scoring
Palgrave Macmillan (2013)The last years have seen the development of many credit scoring models for assessing the creditworthiness of loan applicants. Traditional credit scoring methodology has involved the use of statistical and mathematical ... -
On the suitability of resampling techniques for the class imbalance problem in credit scoring
Palgrave Macmillan (2013)In real-life credit scoring applications, the case in which the class of defaulters is under-represented in comparison with the class of non-defaulters is a very common situation, but it has still received little attention. ... -
Temporal Distribution and Weather Correlates of Norway Rat (Rattus norvegicus) Infestations in the City of Madrid, Spain
Springer Verlag (2013)Urban Norway rats are challenging pests, posing significant health and economic threats. Implementing ecologically based integrated rodent management (EBIRM) programmes relies primarily on the understanding of ecological ... -
Leveraging electronic healthcare record standards and semantic web technologies for the identification of patient cohorts
American Medical Informatics Association (2013)Background The secondary use of electronic healthcare records (EHRs) often requires the identification of patient cohorts. In this context, an important problem is the heterogeneity of clinical data sources, which can be ... -
A continuous wavelet-based approach to detect anisotropic properties in spatial point processes
World Scientific Publishing (2013)A two-dimensional stochastic point process can be regarded as a random measure and thus represented as a (countable) sum of Delta Dirac measures concentrated at some points. Integration with respect to the point process ... -
Photon Counting 3-D Object Recognition Using Digital Holography
Institute of Electrical and Electronics Engineers (IEEE) (2013)We present an analysis of the recognition performance of 3-D objects reconstructed from digital holograms recorded under photon counting conditions. The digital holograms are computed by applying four-step phase-shifting ... -
