Flows in liquid propellant rocket engines (LRE) are characterized by high pressures and extreme temperature ranges, resulting complex fluid behavior that requires elaborate thermo-physical models. In particular, cubic equations of state dedicated models for transport properties firmly established LRE simulations as a way to account the non-idealities high-pressure fluids. this paper, we review ...

This paper studies a new way of constructing multiple phone tokenizers for language recognition. In this approach, each phone tokenizer for a target language will share a common set of acoustic models, while each tokenizer will have a unique phone-based language model (LM) trained for a specific target language. The target-aware language models (TALM) are constructed to capture the discriminati...

[1] The loads regression estimator (LRE) was introduced by Wang et al. (2011) as an improved approach for quantifying the export of loads and the corresponding uncertainty from river systems, where data are limited. We extend this methodology and show how LRE can be used to analyze a 24 year record of total suspended sediment concentrations for the Burdekin River. For large catchments with high...

The Institute for Infocomm Research (IIR) team submitted two systems, namely the primary iir_primary_llr and the contrastive iir_contrast1_llr, to the 2011 NIST Language Recognition Evaluation (LRE). Both systems are based on the fusion of multiple classifiers. These classifiers are broadly divided into two groups: acoustic and phonotactic. Included in the submission are the result files: iir1/...

Pilot application projects will be the major means for stimulating collaboration between users, suppliers and researchers. Building on the successful LRE scheme, these projects will provide a more user-centered context and encourage a coordinated and market-driven approach to RTD tasks, and at the same time demonstrate and validate the integration of language components within information and c...

This paper summarizes recent advances in PRLM language recognition within the context of the NIST 2007 LR evaluations (LRE). We present a comparison of binary decision tree (BT) vs. N -gram models when adaptation from a universal (background) model (UBM) is used, we introduce multi-models— anchor-model-like approach to scoring, and we adopt the framework of intersession variation using factor a...

This paper describes the acoustic language recognition subsystems of Brno University of Technology (BUT) which contributed to the BUT main submission to the NIST LRE 2007. Two main techniques are employed in the subsystems discriminative training in terms of Maximum Mutual Information, and channel compensation in terms of eigenchannel adaptation in both, model and feature domain. The complement...

Abstract In this study, a theoretical and numerical framework for simulating transcritical flows under variety of conditions interest aerospace propulsion applications is presented. A real-fluid multicomponent multiphase thermodynamic model, based on cubic equation state (EoS) vapor–liquid equilibrium (VLE) assumptions, presented to describe mixtures properties. The versatility model reported s...

The oxidative cost of reproduction has been a matter of debate in recent years presumably because of the lack of proper experimental studies. Based on the hypothesis that different brood sizes produce differential reproductive costs, an experimental manipulation during breeding of Adélie penguins was conducted at Hope Bay, Antarctica, to study oxidative status and stress. We predict that a lowe...
