Parsing with Treebank Grammars:Empirical Bounds,Theoretical Models,and the Structure of the Penn Treebank
Treebank Grammars Empirical Bounds Theoretical Models Penn Treebank
2015/6/12
This paper presents empirical studies and closely corresponding theoretical models of the performance of a chart parser exhaustively parsing the Penn Treebank with the Treebank’s own CFG grammar. We s...
Theoretical models of the halo occupation distribution: Separating central and satellite galaxies
formation halos
2014/12/24
The halo occupation distribution (HOD) describes the relation between galaxies and dark matter at the level of individual dark matter halos. The properties of galaxies residing at the centers of halos...
IDENTIFICATION OF THE EXPERIMENTAL DATA OF DYE ADSORPTION ON NATURAL DISPERSED SORBENTS TO THEORETICAL MODELS
adsorption natural dispersed sorbents dyes identification Isotherm theoretical models of adsorption
2011/11/11
The present study deals with removal of organic dyes from wastewater onto natural dispersed sorbents, namely bentonite, glauconite and paligorskyte. The obtained data were fitted to various theoretica...

2012/2/24
As an important branch of biomedical engineering, respiratory mechanics helps to understand the physiology of the respiratory system and provides fundamental data for developing such clinical technolo...
Comparison of some theoretical models for fittings of the temperature dependence of the fundamental energy gap in GaAs
Non-linear behavior of Eg(T) Zero-point energy Temperature dependence of the gap Gallium arsenide
2010/6/30
In this work we report on a comparison of some theoretical models usually used to fit the dependence on temperature of the fundamental energy gap of semiconductor materials. We used in our investigati...

Diurnal-Period Continental Shelf Waves along Vancouver Island：A Comparison of Observations with Theoretical Models
Diurnal-Period Theoretical Models Continental Shelf Waves
2009/1/21
Current and sea level data from the Coastal Oceanic Dynamics Experiment conducted of Vancouver Island from May 1979 to September 1980 reveal shelf waves of diurnal period whose motions dominate the fl...
Financial correlations at ultra-high frequency: theoretical models and empirical estimation
Financial ultra-high frequency
2010/12/13
A detailed analysis of correlation between stock returns at high frequency is compared with simple models of random walks. We focus in particular on the dependence of correlations on time scales - th...
The Epistemological Status of Theoretical Models of Molecular Structure
rigid and dynamic model of molecular structure representation quantum theory of molecular structure
2008/4/7
For many decades, chemists regarded rigid models of molecular structure as representing structures of real molecules as their attributes. However, new experimental data required a new theoretical conc...

Theoretical Models the Study of Temperature Effect Steel Mechanical Properties
2010/8/17
The governing laws adopted by two high qualified scientific organizations (D.T.U. and Eurocode) for the variation of steel mechanical properties at high temperatures are presented. There are no signif...
On Experimental Data of the TCR of TFRs and Their Relation to Theoretical Models of Conduction Mechanism
the TCR TFRs Conduction Mechanism
2010/12/23
Any theory of electrical conduction in TFRs encounters mainly two problems: (i) explanation of the dependence of R□ on properties of conducting component (volume fraction, grain size, resistivity), (i...
