For the significance test of the unknown parameter distributions, a non-parametric method, such as wavelet transformation analysis, is a reasonable choice. A wavelet is a waveform of effectively limited duration that has an average value of zero, and wavelet analysis is the breaking up of a signal into shifted and scaled versions of the original (or mother) wavelet. It provides a multi-scale re...

En las últimas décadas, debido a los fuertes vientos huracanados en México, se han colapsado varias torres autosoportadas para telecomunicaciones, causando pérdidas económicas y sociales importantes. Las de telecomunicaciones son altamente sensibles efectos dinámicos cargas viento. El objetivo este trabajo es comparar la respuesta dinámicade términos desplazamientos, utilizando historias viento...

The thermal neutron background at Laboratorio Subterráneo de Canfranc (LSC) has been determined using several 3He proportional counter detectors. Bare and Cd shielded counters were used in a series of long measurements. Pulse shape discrimination techniques applied to discriminate between gamma signals as well other intrinsic contributions. Montecarlo simulations allowed us estimate the sensiti...

In this work, a block-wise extension of Tikhonov regularization is proposed for denoising smooth signals contaminated by wide-band noise. The proposed method is derived from a constrained least squares problem in two forms: 1) a block-wise fixed-lag smoother with smooth inter-block transitions applied in matrix form, and 2) a fixed-interval smoother applied as a forward-backward zero-phase filt...

We examine the situation where a decision maker is considering investing in a number of projects with uncertain revenues. Before making a decision, the investor has the option to purchase data which carry information about the outcomes from pertinent projects. When these projects are correlated, the data are informative about all the projects. The value of information is the maximum amount the ...

The evaluation of Physically Unclonable Function (PUFs) quality is an open problem, as the PUF represents a circuit signature which depends on process variation but also environmental conditions. Some metrics consisting in analysing the statistics of PUF outputs have been introduced. The considered metrics are often the randomness (max entropy), the uniqueness (two PUFs should be different), an...

Los organismos evaluadores de la conformidad (OEC) acreditados por ISO/IEC 17025 realizan validación resultados, con el fin confirmar mediante revisión competencia técnica provisión evidencia objetiva, evaluando cumplimiento los requisitos normativos necesarios para una aplicación específica [1]. La Guía expresión incertidumbre en medición (GUM) proporciona dos alternativas evaluar y expresar m...
