    Multimedia Compression techniques 4.0 Introduction In this unit we are discussing about the data compression which is very important for multimedia applications because uncompressed graphics‚ audio‚ and video data require considerable storage capacity. Compressing a data file reduces its size‚ and hence it can be easily transferred over the digital network. The amount of compression depends on the compression method and compression rate. The terms compression

    CHAPTER 1 INTRODUCTION Power transformers are very important in the electrical power sector; they are among the expensive assets of power generation and distribution systems. . According to Piush Verma [16]‚ transformers are static electromagnetic devices consisting of two or more windings which are linked with a common magnetic field used for the distribution of electrical power from one voltage level to another. Some of the main parts of the transformer are; the windings‚ tank and insulation

    Micro-Raman Spectroscopy Raman spectroscopy is a micro-analytical method that showed many advantages in analysis of cultural heritage materials. It is a form of vibrational spectroscopy that allows the identification of particles in homogeneous materials in the micron order. The identification is employed on the basis of the molecular vibrational spectra of samples‚ obtained by excitation with visible laser light. In micro-Raman spectroscopy‚ the laser beam is focused by means of a microscope

    domain using Fourier analysis. • Fourier analysis allows us to represent signals as combinations of sinusoids (sines and cosines). Frequency Frequency is the rate at which a signal oscillates. High Frequency Low Frequency Sound Waves • Sound is a pressure wave in a transmission medium such as air or water. • We perceive the frequency of the wave as the “pitch” of the sound. • A single frequency sound sounds like a clear whistle. • Noise (static) is sound with many frequencies.

    Experiment 6 Infra-Red Spectroscopy of HCl and DCl gas Abstract Fourier-transform infrared spectroscopy has been very useful in helping scientists examining molecules of HCl and DCl. Because deuterium has a greater mass than hydrogen‚ the IR band shown for HCl is at a higher wavelength than DCl. The absorption of light in DCl was at lower frequency 1700-2200 cm-1 because D is bigger and heavier. That’s why the vibrations on the IR were shorter for DCl compared to HCl. The stretching of
