regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...

Satellite precipitation products (SPPs) have emerged as an important information source of with high spatio-temporal resolutions, great potential to improve catchment water resource management and hydrologic modelling, especially in data-sparse regions. As indirect measurement, satellite-derived accuracy is major concern. There been numerous evaluation/validation studies worldwide. However, a c...

To generate high-quality spatial precipitation estimates, merging rain gauges with a single-satellite product (SPP) is common approach. However, single SPP cannot capture the pattern of well, and its resolution also too low. This study proposed an integrated framework for multisatellite gauge precipitation. The integrates geographically weighted regression (GWR) improving estimations long short...

the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...

the present research was an attempt to see how quranic lexical collocations were translated into english by two professional translators namely, abdullah yusuf(2005), and muhammad s. shakir(2012). the study attempted qualitatively to shed light on how translators dealt with quranic lexical collocations when transferring them to the target language based on the newmark(1988) model , and quantit...

Smallholder livelihoods throughout Central America are built on rain-fed agriculture and depend seasonal variations in temperature precipitation. Recent climatic shifts this highly diverse region not well understood due to sparse observations, as the skill of global climate products have been thoroughly evaluated. We examine performance for several reanalysis satellite-based data (CHIRPS/CHIRTS...

Monitoring water resources globally is crucial for forecasting future geo-hydro disasters across the Earth. In present study, an attempt was made to assess functional dimensionality of multi-satellite precipitation products, retrieved from CHIRPS, NASA POWER, ERA-5, and PERSIANN-CDR with respect gridded India Meteorological Department (IMD) dataset over a period 30+ years (1990–2021) on monthly...

Gridded satellite precipitation datasets are useful in hydrological applications as they cover large regions with high density. However, not accurate the sense that do agree ground-based measurements. An established means for improving their accuracy is to correct them by adopting machine learning algorithms. This correction takes form of a regression problem, which measurements have role depen...
