Recent air pollution rise in delhi heavy smog enveloped New Delhi last November. One year later‚ levels of particulate matter have hit nearly 20 times what the government considers a standard for health. Inhalable waste in the form of particulate matter 10‚ or PM10‚ hit 1‚940 micrograms per cubic meter in the city whereas The Delhi Pollution Control Committee’s standard for healthy conditions is 100 micrograms per cubic meter or lower. Air quality often deteriorates during the Diwali festival‚

pollutants - decompose rapidly by natural processes. 2. Non-degradable pollutants-do not decompose or slowly decompose in the environment. Pollutions are different kinds 1. Air pollution 2. Water pollution 3. Soil pollution 4. Marine pollution 5. Noise pollution 6.Thermal pollution and 7. Nuclear hazards I-Air pollution: It may be defined as “the presence of one or more contaminants like dust‚ smoke‚ mist and odour in the atmosphere which are injurious to human beings‚ plants and animals Sources

In 1945 Arthur C. Clarke wrote an article entitled "The Future of World Communications" for the magazine Wireless World. This article‚ which the editors renamed "Extra-Terrestrial Relays"‚ was published in the October issue. In it Clarke described the properties of the geostationary orbit‚ a circular orbit in the equatorial plane of the earth such that a satellite appears to hover over a fixed point on the equator. The period of revolution is equal to the period of rotation of the earth

Air Pollution -occurs when gases‚ dust particles‚ fumes (or smoke) are introduced into the atmosphere in a way that makes it harmful to humans‚ animals and plant. This is because the air becomes dirty or contaminated. -the introduction into the atmosphere of chemicals‚ particulates‚ biological materials that cause discomfort‚ disease‚ or death to humans‚ damage other living organisms Air Pollutants -Things that pollute the air -A substance in the air that can be adverse to humans and the environment

instantaneous bandwidth hence it offers substantial increase in channel capacity‚which can be perceived from Shannon link formula: C=Blog(1+SNR). The link capacity is proportional to bandwidth and and follows a logarithmic relation with signal to noise ratio.Due to linear relationship between channel capacity and bandwidth ‚a very small radiation power is needed to achieve high data rate when the signal bandwidth is large.The frequency domain spectral content of UWB signal is dependent upon pulse

used in the local statistics calculation for PCA transform estimation‚ so that the image local features can be well preserved after coefficient shrinkage in the PCA domain to remove the noise. The LPG-PCA denoising procedure is iterated one more time to further improve the denoising performance‚ and the noise level is adaptively adjusted in the second stage. Experimental results on benchmark test images demonstrate that the LPG-PCA method achieves very competitive denoising performance‚ especially
