Studied in this paper are hybrid multirate lter banks which consist of analog analysis lters, slow A/D converters, digital expanders, and digital synthesis lters. The synthesis lters are designed to minimize the maximum energy gain of the error system, suitably weighted, between the lter bank and a fast A/D converter with some time delay. This hybrid and… (More)
OBJECTIVE Peripheral hearing loss has been commonly reported in children with non-syndromic cleft lip and/or palate (NSCLP) but few studies have provided information about central auditory nervous system (CANS) functioning for this group. The main objective of this study was to explore CANS functioning in infants with NSCLP through analysis of auditory… (More)
OBJECTIVE To investigate possible structural abnormalities of the central auditory pathway in infants with nonsyndromic cleft lip and/or palate (NSCL/P). PARTICIPANTS Twenty-seven Chinese infants with NSCL/P, aged from 6 to 24 months. INTERVENTION Morphological magnetic resonance imaging (MRI) measurements of the central auditory nervous system (CANS)… (More)
The design, configuration, operation and maintenance of configuration files in intelligent substation are currently still utilizing the models for secondary system of regular substation. The disadvantages, such as the separation of design and configuration and the lack of control means in configuration files, make the configuration files in the fade zone of… (More)
This paper examines the drivers of internationalization for multinational corporations from developing economies. Based on resource dependence and institution theory, this paper uses firm-level and country-level factors to systematically assess the reasons for internationalization of MNEs from developing countries. We find that technological and human… (More)
In accordance with the definition and properties of Dedekind Sums, this paper studies Dedekind sums involving a category of 2-order linear recurrence sequences, and obtains an estimated result of a sort of sum. The conclusion generalizes a result from Hu Hong, involving Fibonacci numbers and Dedekind sums.
For a single-machine, innnite-bus power system, several digital robust stabilizers with single-rate and multirate sampling schemes are designed using modern H1 optimization. The digital stabilizers designed have low orders, require considerably slow sampling rates for implementation, and out-perform the conventional (analog) power system stabilizer on a… (More)
