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 ...

The life of Herbert Windsor Mumford exemplifies the advent and progression of the professional Animal Scientist in the Land-Grant Institutions of the country. His successive roles from student of Animal Husbandry through the highest administrative posts in agricultural education, experimentation and extension, and contributions to agricultural policy and programs on a national level established...

In this paper, we introduce the ideas of Informed Reinforcement Learning, an extension of Relational Reinforcement Learning, in which partial world models are being learned, in order to improve convergence to the optimal policy, using goal-oriented reasoning. Furthermore, an algorithm is presented to enhance an RRL-agent with reasoning capabilities.

We propose an extension to the HTTP protocol that allows specification of domain borders in the form of fences – a service provider is empowered with the ability to specify what exactly they would like to accept as being within their domain. The extension also provides a second asset which is a policy specification or data visa; these visas specify what types of data can be brought into the fen...

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...

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...

BACKGROUND Determining the effectiveness of social and psychological interventions is important for improving individual and population health. Such interventions are complex and, where possible, are best evaluated by randomised controlled trials (RCTs). The use of research findings in policy and practice decision making is hindered by poor reporting of RCTs. Poor reporting limits the ability t...

this paper examines the economic effects of investment in developing and introducing almond late flowering cultivars (alfc) in a period of 52 years from 1968 to 2020, developed in sahand horticultural research station (shrs), using the economic surplus model and field survey data. alfc make almond supply curve move less to the left when there is a chilling case, thus affect the economic surplus...

Applying reinforcement learning in large Markov Decision Process (MDP) is an important issue for solving very large problems. Since the exact resolution is often intractable, many approaches have been proposed to approximate the value function (for example, TD-Gammon (Tesauro 1995)) or to approximate directly the policy by gradient methods (Russell & Norvig 2002). Such approaches provide a poli...
