applications. For instance‚ researchers have developed and tested cylindrical membranes with pores tiny enough to filter out the smallest organisms. Carbon nanotube filters The nanotube based water filters are found to filter bacteria and viruses and are more resilient and reusable than conventional membrane filters. The filters could be cleaned by heating the nanotube filters. Nano engineered membranes allowed

With Brita reluctant to explore the alternative options quickly‚ other competitors such as PUR‚ have gained a firmer foot-hold in terms of market-share relative to Brita. Secondly‚ the introduction of Faucet-mounted (FM) filter into the market by PUR in 1998 and its subsequent collaboration with Procter and Gamble (P&G) has meant

improve it in some way. It is characterized by the representation of discrete time‚ discrete frequency‚ or other discrete domain signals by a sequence of numbers or symbols and the processing of these signals. The goal of DSP is usually to measure‚ filter and/or compress continuous real-world analog signals. The first step is usually to convert the signal from an analog to a digital form‚ by sampling and then digitizing it using an analog-to-digital converter (ADC)‚ which turns the analog signal

The first is labelled as Valley A‚ and was obtained from a field which has been known to be uncultivated for 10 years in the valley. Valley B was obtained from a domestic garden‚ under a Magnolia tree in the same region. At times when a third sample was tested‚ the source will be indicated

(Performed using MATLAB Central routine regiongrowing.m provided by Dirk-Jan Kroon.) Several seeds can be used in region growing to segment multiple objects or parts of one object. Significant interaction may be required to get the desired results. As with clustering using K-means‚ pixel values can be replaced by textures on small blocks to get a segmentation
