The most general problem of today's environment is the presence of dust. The dust stability in air will lead to instability in human routine in the form of health disorders. The filtration of this kind of impurities from air is one of the best possib
In the last few years design of two dimensional has grown sufficient zest among researchers. The design of two dimensional finite impulse response FIR filters can be expound as a non linear optimization problem. The constraints are high and estimatio

Coupons, like the one shown abo+e, are small pieces of the same type of metal used in the distribution system piping$ These coupons are inserted into pipes at +arious locations in the distribution system and are left in place for about three months to gi+e ade-uate time for corrosion to occur$ 8y weighing the coupon before and after the test period, the amount of metal lost from the coupon due to corrosion can be determined$ This is a simple method of corrosion monitoring which is widely used in many distribution systems$
low monitoring can also be used to detect corrosion$ A new piece of pipe is placed in ser+ice and the flow of water through the pipe is measured o+er time$ If the flow becomes lower after a few weeks, then either tubercles or scale ha+e formed on the inside of the pipe, decreasing the area a+ailable to carry water$
'(ort@Term Testing 7issol+ed o"ygen and to"ic hea+y metals in the distribution system can be used as indicators of corrosion o+er a much shorter time frame$ There are also a range of tests done at the water treatment plant to determine whether water is stable$ 7issol+ed o"ygen is tested at +arious points in the distribution system at the same time$ If the dissol+ed o"ygen concentration becomes lower further from the treatment plant, then the o"ygen is probably being used up by corrosion$ %owe+er, the operator should be aware of the possibility that 7$!$ is being used to o"idi6e organic matter$ To"ic hea+y metals, such as copper and lead, are tested at the consumer's tap$ %igh concentrations of these metals in the water indicate corrosion in the distribution system, although in a few cases the metals may ha+e originated in the source water$ inally, water can be tested directly to determine whether it is stable$ 8oth theLangelier Inde6 and the *arble Test are laboratory tests which can determine the degree of calcium carbonate saturation in the water at the treatment plant$ Water
