A method is presented for impact evaluation of dams/sluices on their downstream aquatic ecosystems in the absence of detailed long-sequence ecology ecosystem data. It is based on the analysis of relations between indices of water quality and aquatic organisms. It can be applied to a river...

This study aims to interpret and analyze images of forest fires and to establish a standard procedure for image processing and interpretation. A forest fire in Victoria, Australia, that occurred in 2009 is used as an example. The extent of the disaster can be analyzed from Formosat-2 images and...

The active Chihshang fault in the southern segment of longitudinal valley of eastern Taiwan is part of the suture boundary between the Eurasia plate and the Philippine Sea plate. Radon anomalies in groundwater were recorded prior to three major earthquakes—(1) 2003 M <Subscript>w</Subscript> = 6.8 Chengkung, (2)...</subscript>

Poly(phthalazinone ether nitrile) (PPEN) block copolymers containing polysiloxane were prepared so as to create a strongly hydrophobic polymer surface. The copolymers were synthesized from eugenol end-capped polydimethylsiloxane (PDMS) and fluoro-terminated PPEN oligomers by the aromatic...

When a rectangular multivariate data set contains missing values, missing data imputation using the multivariate t distribution appears potentially useful, especially for robust inferences. An efficient technique, called the monotone data augmentation algorithm, for implementing missing data...

This article studies a sample of 225 Chinese A-share Seasoned Equity Offerings (SEOs) from 1999 to 2007. We compare a novel underpricing measure with a Stochastic Frontier Approach (SFA) as in Koop and Li (2001) to the conventional measure based on the difference between primary market price and...

To both collect terrain data rapidly and save labor costs, the present study employs high-spatiotemporal-resolution imaging through Formosat-2 and aerial photography through unmanned aerial vehicles. In daily visits to the same area, images taken by Formosat-2 can be employed as data for...
