Its weird how some people don’t question the things that are obvious to us. The things we see‚ how do we see it? What makes it visible to us? Is it only because we have eyes‚ or is there another factor. The great Aristotle explained it by having something in our eyes that emits “something” to an object and that’s why things are visible to us.

which different frequencies are analyzed with different resolutions. A wave is an oscillating function of time or space and is periodic. In contrast‚ wavelets are localized waves. They have their energy concentrated in time or space and are suited to analysis of transient signals. While Fourier Transform and STFT use waves to analyze signals‚ the Wavelet Transform uses wavelets of finite energy.

requires ongoing assessment‚ high expectations and a secure knowledge of what children need to acquire to progress. The implementation of interventions can be explained by the National Strategy which described a three wave model of teaching.
