A reliable speech enhancement method is important for speech applications as a pre-processing step to improve their overall performance. In this paper, we propose a novel frequency domain method for single channel speech enhancement. Conventional frequency domain methods usually neglect the correlation between neighboring time-frequency components of the signals. In the proposed method, we take...

We consider a class of Hamiltonians with three degrees of freedom that can be mapped into quasi-periodically driven pendulums. The purpose of this paper is to determine the threshold of the break-up of invariant tori with a specific frequency vector. We apply two techniques : the frequency map analysis and renormalizationgroup methods. The renormalization transformation acting on a Hamiltonian ...

introduction the aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (appj) and interactions of this technology with double-stranded dna using the polymerase chain reaction (pcr) and single-strand conformation polymorphism (sscp) techniques. materials and methods the plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...

In contrast to what Wålinder et al. (2005) concluded in their article “Acute Effects of a Fungal Volatile Compound,” I interpret the article to report essentially no effects beyond chance. In all, the authors carried out some 76 comparisons (each one representing a time point and an exposure vs. control measurement) if you take blink frequency as a single comparison. The authors reported findin...

PURPOSE To prospectively evaluate the effectiveness of home-based computer vergence therapy for the treatment of binocular vision disorders in adults at least 3 months after an acquired brain injury. METHODS Eligibility criteria included presence of binocular dysfunction characterized by receded near point of convergence (≥6 cm break), insufficient positive fusional vergence at near (failing ...

Objective(s): Application of eco-friendly materials like poly lactic acid (PLA) is increasing, to reduce environmental pollutions. In this research, the effect of silicon dioxide 1%, 3% and 5% nanoparticles on morphological, mechanical and chemicals interaction (FTIR) of PLA film was studied. Materials and Methods: Scanning electron microscope (SEM) was used, ...

We revise the classic methodology to find the multi-product break-even point. In the current paper we propose a solution to the problem under uncertainty conditions, based on Durán Herrera’s crisp approach [3] and applying fuzzy linear programming. We introduce the concept of approximate break-even for cases in which, due to the nature of the problem, it is not possible to find the break-even p...

This article considers the break in viscosity curves that appears in the glass transition region. It demonstrates that the only possibility to interpret properly the break within the frameworks of the activation energy theory is to assume that at least several independent processes are taking place. Single process cannot explain the break. This assumption was already developed in details in the...

Given a parse tree for a sentence xzy and a string Z, an incremental parser builds the parse tree for the sentence xZy by reusing as much of the parse tree for xzy as possible. The incremental LL(1) parsing algorithm in this paper makes use of a break-point table to identify reusable subtrees of the original parse tree in building the new parse tree. The break-point table may be computed from t...
