To celebrate the birth anniversary of Father of Statistics, Prof. Prasanta Chandra Mahalanobis and to recognize his invaluable contribution in establishing the National Statistical System and to understand how statistics is applied in framing socio-economic policies, Department of Mathematics, SRMIST, Ramapuram has organized an Expert Talk on “Applications of Probability & Statistics in Defence” as part of National Statistics Day on 29.06.2022.
Date & Time:
02.30 PM IST
Topic: “Applications of Probability & Statistics in Defence”
Dr. P. Vasundhra
Centre for Engineering,
Analysis and Design,
Combat Vehicles Research and Development Establishment,
Dr.Vasundhra commenced the session with a short introduction about DRDO and CVRDE (Defence Research and Development Organization Combat Vehicles Research Development Establishment). She explained about the applications of Probability and Statistics in DRDO.
Dr.Vasundhra explained in detail how probability has been applied in Modeling of First Round Hit Probability (FRHP) of main gun in Armoured Fighting Vehicles (AFVs) and she explained how normal and uniform distributions have been applied in calculating one sigma and two sigma errors occuring while framing the mathematical model FRHP.
Dr.Vasundhra defined the term ballistic limit – it is the minimum velocity to completely penetrate the armor plates. She explained the statistical approaches which are used for estimation of V50 ballistic limit velocity – which is the velocity at which a specific projectile (bullet) is expected to penetrate the armor half of the time (i.e.complete penetration and incomplete penetration are equally likely to occur). She further explained about V0 – maximum velocity at which no complete penetration will occur and V100 – minimum velocity at which all projectiles will completely penetrate.
Dr.Vasundhra explained the Mathematical models namely – Basic Model, Nucleation Model, Coalescence Models where lognormal distributions have been applied to simulate the processing of ceramic foams and estimation of pore size distribution in ceramic foams.
Dr. Vasundhra concluded the session by responding to all the quieries raised by the participants. More than 150 Participants got an idea about the applications of probability and statistics in real world.
