TL;DR: In this paper, simplified electrical models of a fuel cell generation system for system control are proposed, and using the electrical models, system performance of a FCL generation system in which power is boosted by step-up choppers is analyzed.
Abstract: The fuel cell generation system consists of a stack, a reformer, and converters. The stack generates DC power by electrochemical reaction. For system design and analysis, it is necessary to obtain electrical models. Simplified electrical models of a fuel cell generation system for system control are proposed. Then using the electrical models, system performance of a fuel cell generation system in which power is boosted by step-up choppers is analyzed. A fuzzy controller is designed for improved system performance. Simulation and experimental results confirmed the high performance capability of the designed system.

TL;DR: In this article, a semiparametric method for estimating general patterns of cross-sectional specific time trends is proposed, which is related to principal component analysis and estimate the time-varying trend effects using a small number of common functions calculated from the data.
Abstract: This paper introduces a new estimation method for arbitrary temporal heterogeneity in panel data models. The paper provides a semiparametric method for estimating general patterns of cross-sectional specific time trends. The methods proposed in the paper are related to principal component analysis and estimate the time-varying trend effects using a small number of common functions calculated from the data. An important application for the new estimator is in the estimation of time-varying technical efficiency considered in the stochastic frontier literature. Finite sample performance of the estimators is examined via Monte Carlo simulations. We apply our methods to the analysis of productivity trends in the U.S. banking industry.

TL;DR: Evaluating the reliability and validity of six methods of measuring version of the acetabular component after total hip replacement (THR) recommended the use of the methods described by Lewinnek, Hassan et al, Liaw et al and Woo and Morrey.
Abstract: A variety of radiological methods of measuring
version of the acetabular component after total hip replacement (THR)
have been described. The aim of this study was to evaluate the reliability
and validity of six methods (those of Lewinnek; Widmer; Hassan et
al; Ackland, Bourne and Uhthoff; Liaw et al; and Woo and Morrey)
that are currently in use. In 36 consecutive patients who underwent
THR, version of the acetabular component was measured by three independent
examiners on plain radiographs using these six methods and compared
with measurements using CT scans. The intra- and interobserver reliabilities
of each measurement were estimated. All measurements on both radiographs
and CT scans had excellent intra- and interobserver reliability
and the results from each of the six methods correlated well with
the CT measurements. However, measurements made using the methods
of Widmer and of Ackland, Bourne and Uhthoff were significantly
different from the CT measurements (both p < 0.001), whereas
measurements made using the remaining four methods were similar
to the CT measurements. With regard to reliability and convergent
validity, we recommend the use of the methods described by Lewinnek,
Hassan et al, Liaw et al and Woo and Morrey for measurement of version
of the acetabular component.

TL;DR: This study proposes a fast multi-label feature selection method based on information-theoretic feature ranking and demonstrates that the proposed method generates a feature subset significantly faster than several other multi- Label feature selection methods for large multi- label data sets.
