Abstract Cloudiness or formation is a concept routinely used in industry to address deviations from homogeneity nonwovens and papers. Measuring cloudiness index based on image data common task industrial quality assurance. The two most popular ways of quantifying are power spectrum correlation function the one hand Laplacian pyramid other hand. Here, we recall mathematical basis first approach ...

This study was conducted to investigate the effect of main emulsion components namely, modified starch, propylene glycol alginate (PGA), sucrose laurate and sucrose stearate on creaming index, cloudiness, average droplet size and conductivity of soursop beverage emulsions. Generally, the use of different emulsifiers or a mixture of emulsifiers has a significant (p < 0.05) effect on the response...

Ecosystem light use efficiency (LUE) is a key factor of production models for gross primary production (GPP) predictions. Previous studies revealed that ecosystem LUE could be significantly enhanced by an increase on diffuse radiation. Under large spatial heterogeneity and increasing annual diffuse radiation in China, eddy covariance flux data at 6 sites across different ecosystems from 2003 to...

On NOAA satellite data the cloudiness in Northern Asia region (80°-175°E; 40°-74°N) was obtained and the research of impact of solar-terrestrial connections on cloudiness has been carried out. The examined region was divided into three latitudinal zones (“southern” zone 40°N-56°N, “central” zone 56°N-66°N and “northern” zone 66°N-74°N) and influence of variations of cosmic rays intensity on val...

The authors exploit three years of data from the CloudSat and Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellites to document for the first time the seasonally varying vertical structure of cloudiness throughout Antarctica and the high-latitude Southern Ocean. The results provide a baseline reference of Southern Hemisphere high-latitude cloudiness for future o...

Forecasting of solar irradiance will become a major issue in the future integration of solar energy resources into existing energy supply structures. As far as short-term time horizons (up to 2h) are concerned, satellite data are a high quality source for information about radiation with excellent temporal and spatial resolution. Due to the strong impact of cloudiness on surface irradiance the ...

in this study, estimation of global and diffuse solar radiations of selected cities in nigeria was carried out to assess the feasibility of solar energy utilization. the results of this work show the variation of direct and diffuse component of solar radiation in summer and winter months. the contribution of diffuse solar radiation is high during the monsoon months whereas sky conditions are cl...

Deforestation in the Amazon region will initially impact the energy balance at the land surface through changes in land cover and surface hydrology. However, continuation of this human activity will eventually lead to atmospheric feedbacks, including changes in cloudiness which may play an important role in the final equilibrium of solar and terrestrial radiation at the surface. In this study, ...
