Prof. Chhanda Samanta, Virginia Military Institute, USA, will deliver a lecture on: A GENERALIZED MASS FORMULA FOR STRANGE AND NON-STRANGE NUCLEI Abstract. In 1953 a strange nucleus called “Hypernucleus” was first discovered that contains a hyperon in addition to neutrons and protons. While neutrons and protons are made of up and down quarks, hyperons are made of different combinations of up, down and strange quarks. Since its first discovery, about 50 different strange-nuclei have been found with different “strangeness”. In March 2010, a strange anti-hypernucleus called, anti-hypertriton was discovered at Brookhaven National Laboratory, USA that gave a glimpse of the [...]

Prof. Dimple Chalishajar, Virginia Military Institute, USA, will deliver a lecture on: EXACT AND TRAJECTORY CONTROLLABILITY OF NONLINEAR AND FRACTIONAL ORDER SYSTEMS: A THEORETICAL AND AN ANALYTICAL APPROACH Abstract. Study of nonlinear systems is important since most of the practical systems are nonlinear in nature. There are different notions of controllability like complete controllability, approximate controllability, exact controllability, partial exact controllability, null controllability, local controllability, etc. A current notion of controllability namely Trajectory controllability (T - controllability) has been introduced as a new direction in the field of control theory. We have discussed T- controllability of the first and second [...]
