3000–2800 cm−1 range and the C–H stretching bands of methyl groups and methylene groups are readily differentiated. For methyl groups‚ asymmetric C–H stretching occurs at 2870 cm−1 ‚ while symmetric C–H stretching occurs at 2960 cm−1 . By comparison‚ methylene groups show asymmetric stretching at 2930 cm−1 and symmetric stretching at 2850 cm−1 . C–H bending gives rise to bands in the region below 1500 cm−1 . Methyl groups produce two bending bands‚ i.e. a symmetrical band at 1380 cm−1 and an asymmetrical

familiar type of symmetry for many people is geometrical symmetry. A geometric object is said to be symmetric if‚ after it has been geometrically transformed‚ it retains some property of the original object (i.e.‚ the object has an invariance under the transform). For instance‚ a circle rotated about its center will have the same shape and size as the original circle. A circle is then said to be symmetric under rotation or to have rotational symmetry. The type of symmetries that are possible for a geometric

SECURITY IN COMPUTING ABSTRACT In this technical paper a session based symmetric key cryptographic technique‚ termed as SBSKCT‚ has been proposed. This proposed technique is very secure and suitable for encryption of large files of any type. SBSKCT considers the plain text as a string with finite no. of binary bits. This input binary string is broken down into blocks of various sizes (of 2k order where k = 3‚ 4‚ 5‚ ….). The encrypted binary string is formed by shifting

affecting beat frequency of a coupled pendula system. Abstract In the course of this experiment‚ I investigate how the mass of the counter-weight affects the beat frequency‚ when the system is put into the perfect superposition of the symmetric and anti-symmetric modes. I then go onto to explore different factors and other ideas involved with coupled pendula systems. Essential Theory In order to gain understanding on the workings of these phenomena‚ I will be starting with the mathematical expressions

the Waldboost algorithm [12] by which the positive training patterns are treated in a similar way as non-face patterns‚ called symmetric bootstrap. In the symmetric bootstrap‚ both the easy positive- and easy negative- patterns are stepwise replaced with more difficult ones and hence bigger space of faces is explored in the training. In order to show the effect of symmetric bootstrap‚ sufficiently large pool of positive training patterns had to be found and the non-face distribution appropriately modeled
