Image retrieval method based on Euclidian distance between normalized features with their mean and variance in feature space is proposed. Effectiveness of the normalization is evaluated together with a validation of the proposed image retrieval method. The proposed method is applied for discrimination and identifying dangerous red tide species based on wavelet utilized classification methods to...

A GPS system was designed to carry out so-called ‘tide-independent’ bathymetric measurement, in order to compare with the conventional technique in which the tidal observations are made at tide gauges along the coast. Through the estimation and introduction of attitude parameters and height corrections, both based on the GPS solutions, the tide-independent bathymetric measurement can be impleme...

Introduction: Previously, a variation of the Transition to Driven Equilibrium (TIDE) [1] called LOW-TIDE for Linear filter-based Optimal Window TIDE [2] approach to catalyzing the steady-state signal during continuous acquisition of image data in balanced SSFP had been presented. The LOW-TIDE technique has the advantage of smaller signal fluctuations at off-resonance frequencies for relatively ...

This study presents an analysis on the factors contributing to groundings when ships transit in and out of ports. The study has been part of a three-year project on “Ship Transit Risk”. By verifying the grounding location database generated during the first two years of the project against the United States Coast Guard’s grounding accident data, an updated database was established in this resea...

This study sets out to investigate the changes in the perception of women in leading positions in communist and postcommunist Romania. The study uses a noninvasive paradigm of analyzing the content of obituaries for women and men in leading positions published in a national journal, and shows that the gender gap in management widened during the postcommunist period. In postcommunist Romania, wo...

The Size of the Shadow Economies of 145 Countries all over the World: First Results over the Period 1999 to 2003 Using the DYMIMIC approach, estimates of the shadow economy in 145 developing, transition, developed OECD countries, South Pacific islands and still communist countries are presented. The average size of the shadow economy (in percent of official GDP) over 2002/2003 in developing cou...

Florida red tide is caused by Karenia brevis, a dinoflagellate that periodically blooms, releasing its potent neurotoxin, brevetoxin, into the surrounding waters and air along the coast of the Gulf of Mexico. Exposure to Florida red tide toxins has been associated with adverse human health effects and massive fish and marine mammal deaths. The articles in this mini-monograph describe the ongoin...
