La envolvente de los edificios como generador de calor y energía eléctrica

[ES]El presente documento analiza las principales funciones que se le exigen actualmente a un sistema constructivo; concretamente, a la envolvente de los edificios. Se plantean inicialmente las causas y necesidades que han derivado en el nuevo concepto de envolvente así como las nuevas funciones que se le son exigibles. Se describen los conceptos relativos a los diferentes sistemas constructivos, a los métodos de ventilación natural y, a continuación, se analizan los criterios de generación fotovoltaica y solar térmica en los edificios, además de la integración de estos sistemas en los edificios. También se analizan los fundamentos sobre materiales de cambio de fase. Todo ello permite presentar los criterios de construcción de edificios ecoeficientes. Asimismo se presentan una serie de soluciones arquitectónicas desde el punto de vista de la eficiencia energética.

A uniform phase representation for the harmonic model in speech synthesis applications

Feature-based vocoders, e.g., STRAIGHT, offer a way to manipulate the perceived characteristics of the speech signal in speech transformation and synthesis. For the harmonic model, which provide excellent perceived quality, features for the amplitude parameters already exist (e.g., Line Spectral Frequencies (LSF), Mel-Frequency Cepstral Coefficients (MFCC)). However, because of the wrapping of the phase parameters, phase features are more difficult to design. To randomize the phase of the harmonic model during synthesis, a voicing feature is commonly used, which distinguishes voiced and unvoiced segments. However, voice production allows smooth transitions between voiced/unvoiced states which makes voicing segmentation sometimes tricky to estimate. In this article, two-phase features are suggested to represent the phase of the harmonic model in a uniform way, without voicing decision. The synthesis quality of the resulting vocoder has been evaluated, using subjective listening tests, in the context of resynthesis, pitch scaling, and Hidden Markov Model (HMM)-based synthesis. The experiments show that the suggested signal model is comparable to STRAIGHT or even better in some scenarios. They also reveal some limitations of the harmonic framework itself in the case of high fundamental frequencies.
