This paper presents a lumped and distributed element models for dual-band (f1/f2) with harmonic suppression (HS) ±90° unit module. At first, the lumped and distributed element models for the dual-band (2.45/5.2-GHz) unit module are constructed. Then, the scattering parameter responses of the unit models are simulated and compared by using general microwave circuit software, such as Agilent ADS™ etc...
This study treated 624 listed companies of non-finance and non-insurance industries in Taiwan, and analyzed the relation between derivative financial product hedging and corporate characteristics, as well as the factors influencing hedging decision-making and hedging tool selection. This study is based on event history analysis to deal with the issues of restricting, equivalence and discrete time...
Based on empirical data of twenty third-party logistic providers in America, this study adopts DEA and cluster analysis to evaluate the key factors in performance assessment. It was found that returns of scale of DMUs' status influenced efficiency ranking. The A&P model is shown useful in distinguishing efficient DMUs, while for inefficient DMUs the cross efficiency model is excellent. Empirical...
