Influences of Test Conditions and Mixture Proportions on Property Values of Soil Treated with Cement to Represent the Wet Method of Deep Mixing
… program was conducted on cement-treated soil mixtures fabricated to represent materials produced by the wet method of deep mixing. The testing program focused on investigating the influences that variations in laboratory testing conditions and in the mix design have on measured property …

Topic Model-based Mass Spectrometric Data Analysis in Cancer Biomarker Discovery Studies
… the underlying "topics" (sources) and their mixture proportions in composing the heterogeneous data. Additionally, denoise deconvolution model (DMM) is proposed to capture the noise signals in samples based on purified profiles. Variational expectation-maximization (VEM) and Markov chain …

The Generalized Linear Mixed Model for Finite Normal Mixtures with Application to Tendon Fibrilogenesis Data
… generalized linear mixed model for finite normal mixtures (GLMFM), as well as the estimation procedures for the GLMFM model, which are widely applicable to the hierarchical dataset with small number of individual units and multi-modal distributions at the lowest level of clustering. The modeling …

Haplotype-Based Approaches For The Study Of Human Evolution
… hierarchical model to assign variants to mixture proportions of identical-by-descent or recurrent variants. By identifying recurrent mutations, we can better understand the spectrum of recent mutations in human populations, the source of genetic variation driving evolution and a key factor …

Compressive Creep of a Lightweight, High Strength Concrete Mixture
… with a lightweight, high strength concrete mixture (LTHSC). Laboratory test specimens have been cast using the concrete materials and mixture proportions used in the fabrication of the bridge beams. Two standard cure and two match cure batches have been loaded for 329 and 251 days, …

Microstructure, Quasi-Static, And High-Strain Rate Dynamic Characterization Of Metakaolin And Fly Ash Based Geopolymers For Structural Applications
… are widely used, and are available in different mixture proportions [1, 2]. Metakaolin (Al2Si2O7), a dehydroxylated form of Kaolinite (Al2Si2O5(OH)4) clay readily available from many sources, provides several benefits whenadded to a concrete mix design or used as a mortar system, including …

Creep and Shrinkage of a High Strength Concrete Mixture
… prepared with identical materials and similar mixture proportions to those used at Bayshore. The temperature profile from the test beams during steam curing was used to produce match-cured specimens for laboratory testing. Two match cure batches were produced, along with two standard cure …

Selecting material constituents and proportions for specific roller-compacted concrete mechanical properties
… design procedures select mix constituents and proportions based on strength requirements, workability, and field density. Discrepancies in mechanical properties are known to exist between field and laboratory compacted specimens. In order to move toward designing and constructing …

Polypropylene fiber reinforced concrete in railway crossties
… to evaluate the performance of various concrete mixtures reinforced with synthetic polypropylene macro fibers. It was found out that the concrete with higher fiber proportions showed significantly higher residual load carrying capacity (post-cracking response). Moreover, the concrete mixtures had …

The presence and growth characteristics of Listeria monocytogenes in blue crab (Callinectes sapidus) meat and the effectiveness of microwave energy in a pasteurization process
… growth curves. This was observed for three mixture proportions of L. monocytogenes and L. innocua, during 15 days, at 4 and 36 °C. Fresh blue crab meat, classified according to the initial levels of microflora (APCs) into three different categories (< 15,000, 15,000-60,000 and, …

Recurrent-Event Models for Change-Points Detection
… among drivers by a hierarchical Bayesian finite mixture model; the third part develops a non-parametric Bayesian model with a Dirichlet process prior. In the first part, two recurrent-event change-point models to detect the time of change in driving risks are developed. The models are based on a …
