The development of an integrated knowledgebased machine-aided translation system based on Systemic Linguistics. Parts of the system are to function as modules to be incorporated in the MAT system being codeveloped with CMU and CRL. Our work involves the enhancement of Penman's existing parsing technology to match the level of the language generation system; the development of ancillary knowledg...

evaporation is a fundamental parameter in the hydrological cycle. this study examines the performance of m5model tree and artificial neural network (ann) models in estimating potential evapotranspiration calculated bypenman- monteith and hargreaves- samani equations. daily weather data from two meteorological stations in asemi-arid climate of iran, namely kerman and zahedan, were collected duri...

We present an approach for the calibration of simplified evaporation model parameters based on optimization against most complex estimation, i.e., Penman–Monteith equation. This computes from several input quantities, such as air temperature, wind speed, heat storage, net radiation etc. However, sometimes all these values are not available, therefore we must use models. Our interest in free wat...

In this paper we describe a framework for research into translation that draws on a combination of two existing and independently constructed technologies: an analysis component developed for German by the EUROTRA-D (ET-D) group of IAI and the generation component developed for English by the Penman group at ISI. We present some of the linguistic implications of the research and the promise it ...

We investigate the equation (ut + (f(u))x)x = f (u)(ux)/2 where f(u) is a given smooth function. Typically f(u) = u/2 or u/3. This equation models unidirectional and weakly nonlinear waves for the variational wave equation utt − c(u)(c(u)ux)x = 0 which models some liquid crystals with a natural sinusoidal c. The equation itself is also the Euler-Lagrange equation of a variational problem. Two n...

The present study develops ArcMap models to implement the following three methods: FAO-56 Penman–Monteith (FAO PM), Hargreaves–Samani (HS) and Hansen, with former used as a reference. Moreover, implementing statistical indices (RMSD, MB, NMB) are also created. purpose is threefold, follows: investigate variability in daily mean reference evapotranspiration (ETo) for Decembers Augusts during 201...

Knowledge of evapotranspiration at various stages plant development allows irrigation management to be more efficiently carried out according the actual crop demand. There are a variety methods that can used determine reference evapotranspiration, and due high variability parameters influencing this phenomenon, it is common have studies compare different evaluate which one has greatest applicab...
