Abstract: Handwriting Analysis or Graphology is a scientific method of identifying, evaluating and understanding personality through the strokes and patterns revealed by handwriting. Handwriting reveals the true personality including emotional outlay, fears, honesty, defenses and many others. Professional handwriting examiners called graphologist often identify the writer with a piece of handwriting. Accuracy of handwriting analysis depends on how skilled the analyst is. Although human intervention in handwriting analysis has been effective, it is costly and prone to fatigue.

Abstract: This paper proposes a new class of ternary zero correlation zone (ZCZ) sequence sets based on mutually orthogonal complementary sets (MOCS), in which the periodic cross-correlation function and the out-of-phase of the periodic auto-correlation function of the proposed sequence set are zero in a specified zone of phase shift. It is shown that the proposed zero correlation zone sequence set can achieve the upper bound on the ternary ZCZ codes.

Keywords - Sequence design, mutually orthogonal complementary sets, theoretical upper bound, zero correlation zone (ZCZ) sequences.

Abstract: This paper presents the effect of the dielectric superstrates on bandwidth and gain of U-slot microstrip patch antenna without superstrate and loaded with superstrates. It is found that there is a degradation in the performance of the antenna when the superstrate is touching the patch antenna i.e the height of the superstrate above the patch H =0 mm. Further, it is also observed that the degraded performance characteristics of the U-slot microstrip patch antenna can be improved by placing the superstrate at optimum height (H) =Hopt.
