Illustrated with Qiantang estuary , Hangzhou Bay, the relationship between structure of coastal geomorphology and dissipation of tidal energy were analyzed and the landscape ecological mechanism of watershed flood was studied based on the theory of the landscape ecology and quantitative assessment method of landscape characteristic index. By Correlation analysis and multiple linear regression analysis...
Tardos constructed the optimal probabilistic codes that are ε-secure against c pirates have length O(c2 log(1/ε)) and are full power of randomization. Many improved versions of Tardos' codes are proposed to shorten its code length while they are still not used in multimedia content. In this paper, the multimedia content tracing scheme based on the Tardos' fingerprint codes is proposed. Before embedding/extracting...
We consider the digital fingerprinting problem where colluders apply uniform linear averaging followed by AWGN. For each user, the receiver computes the correlation between the attacked signal and that user's fingerprint, and performs thresholding (focused detection). We model the fingerprinting problem as a multi-user communications problem and develop a detection theoretic framework. Assuming independent...
Collar rot, caused by Rhizoctonia solani Kühn, is one of the most severe fungal diseases of opium poppy. In this study, heritability, genetic advance and correlation for 10 agronomic, 1 physiological, 3 biochemical and 1 chemical traits with disease severity index (DSI) for collar rot were assessed in 35 accessions of opium poppy. Most of the economically important characters, like seed and capsule...
The aim of the present paper has been to define heritability and mutual relations between frost resistance and the other traits of two- and six-rowed winter barley: yield, 1000 grain weight and grain filling as well as earliness, plant height and resistance to lodging. The research material was made up of winter barley breeding strains of F6-F7 generation researched over 1999-2002 over three two-year...
The aim of the present work was to determine the variability and genetic determination of β-glucan content in the wort of spring barley as well as other significant traits, such as: yield, 1000 kernel weight, earliness, plant height and resistance to lodging and powdery mildew. Also the phenotype correlations between the analysed traits were examined. The objects of the investigation were spring barley...
