E®ective competition in wholesale electricity markets is a necessary feature of a successful electricity supply industry restructuring. We examine the degree of competition in the California wholesale electricity market during the period June 1998 to September 1999 by comparing the market prices with estimates of the prices that would have resulted if owners of instate fossil fuel generating fa...

This paper presents some simulations of the proposed California power exchange, or pool, as it might interact with the regional market in the Western U.S. Pooling will increase interdependence with the regional market. We study this using a multi area chronological production simulation model. We find that overall operating economies resulting from pooling are small. Physical changes in the dis...

Recently, speech pattern analysis applications in building predictive telediagnosis and telemonitoring models for diagnosing Parkinson's disease (PD) have attracted many researchers. For this purpose, several datasets of voice samples exist; the UCI dataset named "Parkinson Speech Dataset with Multiple Types of Sound Recordings" has a variety of vocal tests, which include sustained vowels, word...

This paper investigates the effects of standard speech compression techniques on the accuracy of automatic emotion recognition. Effects of Adaptive Multi-Rates (AMR), Adaptive Multi-Rate Wideband (AMR-WB) and Extended Adaptive Multi-Rate Wideband (AMR-WB+) speech codecs were compared against emotion recognition from uncompressed speech. The recognition methods included techniques based on three...

Keywords: Parkinson's; Self-management; Exercise Purpose: The value of exercise for people with Parkinson's (PwP) is undisputed, and associated improved health outcomes potential to slow down the rate symptom decline. However, optimum means support long-term participation in remains undetermined. Current provision within physiotherapy commonly time limited. Moreover, research has shown that whe...

background: this study aimes to evaluate the failure to thrive (ftt) recurrent event over time. methods: this longitudinal study was conducted during february 2007 to july 2009. the primary outcome was growth failure. the analysis was done using 1283 children who had experienced ftt several times, based on recurrent events analysis. results: fifty-nine percent of the children had experienced th...

There are few studies conducted on the short-term effects of land leveling on soil water holding capacity. The objectives of this study were to analyze the short-term effects of land leveling on the magnitudes, variances, spatial variability, and distributions of surface (0-20 cm) and subsurface (20-40 cm) soil properties of bulk density, field capacity, permanent wilting point, water holding c...

To improve the performance of Automatic Speech Recognition (ASR) Systems, a new method is proposed to extract features capable of operating at a very low signal-to-noise ratio (SNR). The basic idea introduced in this article is to enhance speech quality as the first stage for Mel-cepstra based recognition systems, since it is well-known that cepstral coefficients provided better performance in ...
