Fact-centric information needs are rarely one-shot; users typically ask follow-up questions to explore a topic. In such conversational setting, the user's inputs often incomplete, with entities or predicates left out, and ungrammatical phrases. This poses huge challenge question answering (QA) systems that rely on cues in full-fledged interrogative sentences. As solution, we develop CONVEX: an unsupervised method can answer incomplete over knowledge graph (KG) by maintaining conversation...

Abstract. Particulate emissions can alter the physical and dynamical properties of cloud systems and, in turn, amplify rainfall events over orographic regions downwind highly polluted urban areas. The Indo-Gangetic Plain, one most world, is located upwind Himalayan foothills. region, therefore, provides an opportunity for studying how aerosol effects, connection with forcing, affect extreme events. This study uses 17 years (2001–2017) observed rain rate, optical depth (AOD), meteorological...

Abstract. The Weather and Research Forecast (WRF) model is evaluated for the monsoon inter-monsoon seasons over tropical region of Singapore. configuration, physical parameterizations performance results are described in this paper. In addition to ready-to-use data available with WRF model, configuration includes high resolution MODIS land use (500 m horizontal resolution) JPL-NASA sea surface temperature (1 km data. evaluation performed against near observations temperature, relative...

The main objective of the present study is to rank South African provinces on basis incoming solar radiation. surface incident shortwave flux (SWFlux, Wm-2) NASA Modern-Era Retrospective Analysis for Research and Applications (MERRA 2D) reanalysis data period 1980–2009 over Africa was analysed annual, seasonal monthly scales. mean ± standard deviation values SWFlux revealed that, Northern Cape received most (267.38 4.32 radiation throughout year, followed by North West (263.37 7.13 Free...

Abstract A three‐parameter sigmoidal ‘local’ model (climate‐specific) and a ‘regional’ (common for all climates) have been developed measuring the monthly average diffuse solar radiation fraction from atmospheric transmissivity by using large, 21‐year datasets (1973–1993) over four stations (Jodhpur, New Delhi, Nagpur Kolkata). These represent ‘prime’ climates (arid, semi‐arid, sub‐humid humid) Indian sub‐tropics. The models validated with longer time‐series (10 years) of independent...

Seasonal trends using in situ sunshine duration (SD) and satellite, incoming shortwave solar radiation (SIS) data for South Africa over a period up to six decades were investigated. Trend analysis was applied SD of 22 sunshine-recording stations from the African Weather Service that cover length breadth Africa. Satellite application facility on climate monitoring provided high-resolution derived SIS 1983–2013. A number show statistically significant decreasing trend all four seasons seasonal...

The present work deals with the study of solar radiation trend over four major cities India. Jodhpur, New Delhi, Nagpur, and Kolkata, represent different climate types: arid, semi-arid, sub-humid humid, respectively. For analysis, we have used forty years (1957/60-2003) global (R G ) thirty-one (1973-2003) diffuse D observational data. Based on Mann-Kendall test (MKT) a significant declining in R (solar dimming) has been observed at all stations p<0.05 during 1957/60-2003. decresaing past...

Global dimming term was introduced in 1990s which means the decline global radiation. This reported several studies across world. In present study time series analysis of radiation (1960-2003), transmissivity (1960-2003) and bright sunshine hours (1973-2003) has been done over Nagpur during pre-monsoon (March to May) monsoon seasons (June-September). A significant decrease for both it higher compared monsoon. Bright hour also shown good agreement with previous trend a on months only. Mann...

Present work deals with the analysis of aggregated solar photovoltaic plants output (ASPV_op in kWh) (South Africa) for year 2015.The box plot monthly ASPV_op has shown lower values winter and higher spring summer.The histograms have also been plotted to understand variation different seasons.The confirmed that it is not normally distributed.Monthly was similar surface incident shortwave flux (SISW Wm -2 ).Morlet wavelet used investigation ASPV_op.The power spectrum shows significant (at 5 %...

Computer games are an increasingly popular application for Artificial Intelligence(AI) research.This paper discusses some of the most interesting components and challenges faced by developers in designing creation a game based on artificial intelligence.Game AI provides players richer gaming experience going beyond scripted interactions, responsive interaction systems that adaptive intelligent.

Models of the diffuse fraction daily solar radiation (KD) have been developed over India for different seasons (winter, spring/autumn, and summer/monsoon) using clearness index, also known as atmospheric transmissivity (KT). Measurements global (RG) (RD) made at four stations in climates (Jodhpur—arid, New Delhi—semi-arid, Nagpur—subhumid, Kolkata—humid) used to develop two types empirical models. The “regional” models cover all climate zones “local” are specific. On an average, regional...

The effect of lunar phases on natural disasters has been discussed from time to time. In the present work we have made an attempt investigate impact viz. cyclone, earthquake, slides and floods. We observed increasing trend in number over last 100 years. seasonal analysis above mentioned four shown their maximum occurrence monsoon season. Among allthe disasters, occurrences flood was highestin past It observedthat during first quarter had more compared new moon full moon. However...
