The electromagnetic radiation produced by cellular towers in Ramadi city, west of Iraq, is measured and analyzed this research. This contains basic nodes, hub repeaters, feeders for transmitting the carrier throughout entire city as well surrounding areas. As a result, research focused on area to measure assess energy determine if it safe people or has over danger threshold. study region was sp...

The MOPITT (Measurement of Pollution in the Troposphere) instrument, to be launched on the Earth Observing System Terra platform, employs gas-correlation spectroscopy to measure profiles of tropospheric carbon monoxide and the total column of methane. The modeling of the instrument, and the associated radiative transfer, comprise the forward model employed in the retrieval calculations. The MOP...

Energy efficiency in buildings and facilities has become an important part of the efforts for reducing environmental pollution. In order to develop strategies for efficient allocation of energy resources aimed at reducing power consumption, certain electrical quantities needed for analysis must be measured and monitored. In this paper, we propose a low-cost architecture of the remote electrical...

In many areas of science and engineering, it is desirable to estimate statistical characteristics (mean, variance, covariance, etc.) under interval uncertainty. For example, we may want to use the measured values x(t) of a pollution level in a lake at different moments of time to estimate the average pollution level; however, we do not know the exact values x(t) – e.g., if one of the measuremen...

This study focuses on noise pollution in the Botanical Garden in Curitiba, Paraná, Brazil. Equivalent noise levels (Leq) were measured at 21 points throughout the park, and interviews were conducted with park visitors. Some 47.6% of the measurement sites presented Leq levels over 65dB(A), considered by preventive medicine as the maximum tolerable exposure level without risk of health impairment...

This paper presents results of comprehensive analyses of data from the first 122 commercially available wireless environmental pervasive sensors (motes), developed by Newcastle University and deployed in England. Measurements of pollution, meteorology and traffic are used to investigate the complexity of the physical and chemical processes governing the levels of traffic-related pollution in ur...
