Abstract:

In Reply.— Drs Weyrauch and Boiko cite the examples of Charleston, SC (33 latitude and 862 BTU per day solar radiation in July) and Spokane, WA (48 and 1314 BTU) to illustrate that factors other than latitude affect the overall intensity of solar radiation. Other complexities are worth noting. Cloud cover affects the average intensity of solar radiation, but the peak intensity on sunny days may be particularly relevant for melanoma. Furthermore, it is likely that the short wavelength ultraviolet component of sunlight is primarily responsible for the ability of the sun to cause melanoma, and th

The global solar radiation is measured at the horizontal surface by calibrated pyranometer at Jumla(29.27°N to 82.18°E, 2514.0m). The effect of different physical as well as meteorological parameters to the intensity of global solar radiation was analyzed. This paper compares global solar radiation with sunshine duration, temperature, and rainfall and clearness index. This paper also explains the monthly, seasonal variation of global solar radiation. The annual average global solar radiation is 18.36MJ/m2 /day which is sufficient to promote solar active and passive solar energy technology at H

Emission properties of ZnO nanorods and nanocrystals after high-temperature annealing in air and irradiation with high-intensity solar radiation have been studied. As-synthesized nanorods and nanocrystals under UV radiation exhibit a luminescence with maxima at around 380-384 and 560-570 nm. In both nanostructures, after heat treatment and irradiation with high-intensity solar radiation, an increase in the intensities of the short-wavelength luminescence bands is observed. In addition, after heat treatment and irradiation, in nanorods the long-wavelength luminescence band vanishes, while a new

Abstract:

In algal pond used for treating wastewater, a part of the solar radiation (PAR) is used by algae for photosynthesis, and rest of the solar energy is wasted. To date, no studies have been conducted that optimize these aspects (wasted solar radiation for heat production) from an operational cost perspective. Therefore, a model is developed for the estimation of photosynthetically active radiation (PAR) from solar radiation. Subsequently, derived PAR was utilized in the optimization algorithm. Experimental data on PAR and solar radiation were used to obtain empirical parameters of the developed m

The results show that the crowded buildings at the Lujiazui Region have severely changed the spatial pattern of solar radiation intensity and duration. The derived monthly and seasonal solar ra

The number of solar radiations measuring stations in Nigeria has been observed not to effectively describe the necessary variability; as such prediction models are necessary for estimation of solar radiation values using readily available meteorological variables. In this study, solar radiation parameters were determined for Lafia zone, Nasarawa State, Nigeria. Twelve (12) location were carefully selected to avoid sunshine and wind obstruction using a systematic random sampling technique.

Abstract:

Countries located on the equator have a relatively high intensity of solar radiation. The thing that is most needed in a solar power plant is the intensity of solar radiation. Based on this, Indonesia is very suitable for implementing solar power plants. The power produced by a solar power plant is directly pro-portional to the intensity of solar radiation received by the solar panels. To maximize electrical power production, it is necessary to design a series of solar panel units to be connected in series or parallel. Solar panels connected in parallel will increase the nominal total voltage,

This paper presents an analysis of cosmic ray intensity in Pakistan air space using spatial interpolation, comparing it with Chinese cosmic ray records from 1984 to 1993. The Exploratory Data Analytic (EDA) approach was applied to compare the cosmic ray fluctuations in both countries. The time series plot of the monthly cosmic rays showed relatively flatter counts in Pakistan than in China. The cosmic ray data for the years 1984 to 1993 fell within Solar Cycle 22, which lasted from 1986 to 1996, with its maximum phase in 1989 to 1991.

To ensure that the developed modules were accurate, four problems were selected. The developed codes were tested on these four problems. Correspondingly, the result has shown that the functions generated have helped in a better interpretation and understanding of solar geometry and sun-earth angles</em>

Reliable information on the spatiotemporal dynamics of solar radiation plays a crucial role in studies relating to global climate change.

This paper focus on effects of boosting solar intensity on the thermal performance of solar food dryer coupled with roughened solar heater. Boosting of solar intensity increases the temperature of air entering into the food dryer without changing the specific humidity. The methods which have been used to increase the intensity of incidence radiation on the collector of food dryer are plane mirrors with tracking, parabolic reflectors and compound parabolic concentrator. It has been observed experimentally that boosting intensity improves performance characteristics of solar air heater and food
