The consistent estimation of mixture complexity is of fundamental importance in many applications of finite mixture models. An enormous body of literature exists regarding the application, computational issues and theoretical aspects of mixture models when the number of components is known, but estimating the unknown number of components remains an area of intense research effort. This article ...

We have developed a sophisticated statistical model for predicting the hitting performance of Major League baseball players. The Bayesian paradigm provides a principled method for balancing past performance with crucial covariates, such as player age and position. We share information across time and across players by using mixture distributions to control shrinkage for improved accuracy. We co...

Survival analysis is one of the most important fields statistics in medicine and biological sciences. In addition, computational advances last decades have favored use Bayesian methods this context, providing a flexible powerful alternative to traditional frequentist approach. The objective article summarize some popular survival models, such as accelerated failure time, proportional hazards, m...

we performed molecular dynamics simulations using the coarse-grained model to study the freezing behavior of pure water and 14% water-salt mixture in a wide range of temperatures for a very long time around 50 nanoseconds. for the salty water, an interface in nanoscale was used. for both systems, the freezing behavior of water molecules was studied using some qualities such as density, total en...

shear modulus and damping ratio are important input parameters in dynamic analysis. a series of resonant column tests was carried out on pure clays and sand-clay mixtures prepared at different densities to investigate the effects of aggregate content, confining stress, void ratio and clay plasticity on the maximum shear modulus and minimum damping ratio. test results revealed an increase in the...

The purpose of this study was to (1) analyze the characteristics fresh concrete mixed with sea sand (2) compressive strength water and curing. In study, specimens used were 21 cylinders a job mix design plan f'c 25 MPa curing duration 7 days, 14 28 days. At age days 30.29 33.12 higher than seawater 29.02 32.13 MPa, while at 37. 08 compared 33.97 MPa. Sea has very good quality normal can be in c...

We present a model for discourse coherence which combines the local entitybased approach of (Barzilay and Lapata, 2005) and the HMM-based content model of (Barzilay and Lee, 2004). Unlike the mixture model of (Soricut and Marcu, 2006), we learn local and global features jointly, providing a better theoretical explanation of how they are useful. As the local component of our model we adapt (Barz...
