The aim of this study was to evaluate the rejection rates of bulls in the behavioral assessment (libido and mounting capacity) and the importance of this step in the breeding soundness evaluation of 30,700 beef bulls in the state of Rio Grande do Sul, Brazil. Bulls from the following breeds were evaluated: Aberdeen Angus, Red Angus, Hereford, Polled Hereford, Devon, Shorthorn, Brangus, Braford,...

optimal attributes are useful in interpretation of seismic data. two proposed methods are presented in this paper for finding optimal attributes. regularized discriminate analysis(rda) is based on 2 parameters ë, ? which called regularization parameter. the other method is principal component analysi s(pca).in this paper gas chimney detection is defined as the subject of study for ranking relev...

The pulse generator is the critical component in high-frequency ultrasound imaging systems. Currently, there still exist some shortcomings about commercial ultrasound image systems and devices such as 5900 PR ...etc.. However, to achieve a higher sensitivity and high performance, a programmable pulser generator is desired to match the requirements of high frequency ultrasound image system. In t...

Translation of prepositions poses a very serious problem to machine translation because prepositions are highly ambigous. In theory prepo­ sitions can be disambiguated by a filter that excludes already generat­ ed representational objects with no selection restriction match between preposition and np, but it takes too long time in practice. A neurstl net­ work makes the disambiguation in fracti...

PURPOSE To study the phase aberrations produced by human skulls during transcranial magnetic resonance imaging guided focused ultrasound surgery (MRgFUS), to demonstrate the potential of Zernike polynomials (ZPs) to accelerate the adaptive focusing process, and to investigate the benefits of using phase corrections obtained in previous studies to provide the initial guess for correction of a ne...

Targeted Audience: Researchers and Clinicians interested in using quantitative relaxation measures to the study the effect of physiological and metabolic changes including those associated with neurological and psychiatric disorders on tissue parameters. Purpose: Quantification of multiple tissue parameters is emerging as a powerful tool in diagnosing various neurological and psychiatric diseas...

A bstract In order to generate colloquial language within the computational lin­ guistics paradigm the problems o f co-occurrence must be solved. As of yet research on co-occurrence has mostly focused on problems of syntax and selectional restrictions to describe the contextual relation within the sentence. Collocations and idioms have been neatly put aside as a unified problem to be dealt with...
