The limited audio bandwidth of narrowband telephone speech degrades the speech quality. This paper proposes a method that extends the bandwidth of telephone speech to the frequency range 0–300 Hz. The lowest harmonics of voiced speech are generated using sinusoidal synthesis. The energy in the extension band is estimated from spectral features using a Gaussian mixture model. The amplitudes and ...

This paper utilizes the method of extremal length to study several diameter problems for functions conformal outside of a disc centered at the origin, with a standard normalization, which possess a quasiconformal extension to a ring subdomain of this disc. Known results on the diameter of a complementary component of the image domain of a univalent function are extended. Applications to the tra...

In this paper, we present an extension of the Jaffar-Lassez constraint logic programming scheme that operates with unions of constraint theories with different signatures and decides the satisfiability of mixed constraints by appropriately combining the constraint solvers of the component theories. We describe the extended scheme, and provide logical and operational semantics for it along the l...

there is undoubtedly general agreement that the efficiency of educational investments should he maximized through the managerial process as far as possible. agricultural extension is one of the crucial tasks in developing agricultural societies calling for considerable consumption of intellectual investment. the management of agricultural extension projects (aeps) however, needs careful pla...

Tailorability has long been recognised as a key issue concerning groupware applications in general and componentbased groupware applications in particular. Tailoring activities are usually classified according to three levels, viz., customisation, integration and extension. This paper presents an approach to component-based tailoring based on the use of monitoring extensions. Our approach allow...

We propose in this paper an extension of Besag’s auto-models to exponential families with multi-dimensional parameters. This extension is necessary for the treatment of spatial models like the ones where the conditional distributions are Beta-distributed. A family of cooperative auto-models is proposed. Moreover we apply the result to the analysis of lattice observations which are mixtures of a...

The aim of this paper is to propose a far-reaching extension of the phraseological component of a valence dictionary for Polish. The dictionary is the basis of two different parsers of Polish; its format has been designed so as to maximise the readability of the information it contains and its re-applicability. We believe that the extension proposed here follows this approach and, hence, may be...

A novel speech bandwidth extension method based on audio watermark is presented in this paper. The time-domain and frequency-domain envelope parameters are extracted from the high-frequency components of speech signal, and then these parameters are embedded in the corresponding narrowband speech bit stream by the modified least significant bit watermark method which uses perception property. At...

A 62-year-old man presented with the acute, atraumatic onset of pain 3 years after uncemented right total knee arthroplasty. He complained of new mechanical locking with the knee held in extension on examination and unable to flex the knee. On the plain radiographs, the patellar component peg was fractured and the plate was dislocated. The knee was immobilized, and revision to a cemented 3-peg ...

Software deployment is an inevitable part of software lifecycle. For non-component-based software, there already exist generic tools and environments supporting fully automated deployment. However, for component-based software, there has not been any unified environment and/or suit of tools performing deployment activities yet. This paper proposes such an environment and presents a generic comp...
