This work presents a computational investigation into the scattering of edge guided waves travelling by a notch. To establish a good understanding of this scattering phenomenon, the analysis was conductedon a range of length scales. The finite element analysis indicate that the edge guided surface waves are scattered by the presence of a notch which resulted in a SH0-like appearance wave radiating into the medium. This can be mistaken as a mode conversion of the fundamental lamb modes or even a source at notch tips. The phenomenon becomes harder to notice at higher frequency as increasing the frequency decreases the speed and both the bulk and surface waves travel at identical speeds. A clear understanding of this interaction furthers our knowledge in one of the most prominent interaction in the study of acoustic waves for structural health monitoring.

Tuberculosis, one of the most frequent infectious diseases, is caused by a mycobacterium tuberculosis bacteria and it infects several hundred million people each year, results in several million deaths annually. Because there is development of antibiotic resistance, the disease becomes incurable. So, in the absence of effective and potent drug with minimal resistance problems, the mortality rate increases annually. In this computational investigation, we performed In-silico ADME, bioactivity and toxicity parameters calculation of some selected anti-tuberculosis agents. To design a new molecule having good pharmacological profile, this study will provide the lead information.Key Words: Tuberculosis (TB), Bacillus Calmette-Guerin vaccine, TPSA, In Silico toxicity
