In addition, the project has entered into two collaborations that show great promise. The KOMET project at the IPSI Insti tute in West Germany (funded by the German Federal Government) is a new project with goals very similar to our own. In addition to funding some of our work, they are building a systemic grammar of German and are collaborating on our parsing research. The Department of Lingui...
در این تحقیق میزان تبخیر سالانه و ماهانه از دریاچه سد ساوه (الغدیر) توسط تعدادی از روشها از قبیل روش بیلان آبی و استفاده از تشتک تبخیر، روابط تجربی، روابط نوع Penman، روش بیلان انرژی (BREB) و مدل CRLE به مدت 13 سال (1386-1374) برآورد گردیده است. مقادیر تبخیر سالانه روشهای مختلف مورد استفاده از مقدار حداقل 145 سانتیمتر برای روش Debruin-Keijman تا مقدار حداکثر 175 سانتیمتر برای روش CRLE آبه...
Several studies have projected increases in drought severity, extent and duration in many parts of the world under climate change. We examine sources of uncertainty arising from the methodological choices for the assessment of future drought risk in the continental US (CONUS). One such uncertainty is in the climate models' expression of evaporative demand (E0), which is not a direct climate mod...

the goal of this study was to estimate the sensitivity of reference evapotranspiration (et0) to changes in meteorological parameters in the caspian region. long-term meteorological data (1961-2008) were obtained from three synoptic meteorological stations. the region was primarily classified into three climatic zones, based on de martonne climate classification. the penman–monteith equation was...
A escassez de recursos hídricos é o fator mais limitante da produção agrícola no município Estreito, MA. irregularidade na distribuição das chuvas durante ano, característica regiões tropicais, faz com que a atividade em assim como outras cidades do estado Maranhão reduzam época seca. Diante desse cenário, busca por meios visem melhorar eficiência irrigação para gerenciamento sustentável água s...
The problem of programming computers to produce natural language explanations and other texts on demand is an active research area in artificial intelligence. In the past, research systems designed for this purpose have been limited by the weakness of their linguistic bases, especially their grammars, and their techniques often cannot be transferred to new knowledge domains. A new text generati...
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...
It is necessary that ETr (Alfalfa-reference evapotranspiration) values be converted to ETo (Grass-reference evapotranspiration) or vice versa. The main objective of this study was to develop ETr to ETo ratios (Kr values) for a growing season in Shahrekord plain, Shahrekord, Iran. Mean monthly and total (growing season) values of Kr were calculated based on 185 daily ET data set in Chaharthakhte...
