Ijaz Hussain, Political and Legal Dimensions of Indus Water Treaty (Book Reviews)

Of the many issues that the partition of India in 1947 did not address in time, and were left to worsen the relations between India and Pakistan, the issue of riparian rights was only next in importance to the issue of Kashmir. In many respects the two issues have direct bearing on each other as well, as some important rivers emanate from Indian-held Kashmir. As the time passes more and more historians are coming to the conclusion that the massacre at the time of partition, the uprooting of more than 12 million people from their native homes, horrendous violence against women, burning and looting, etc, all owe mainly to the colonial administration that failed to ensure peaceful transition to two independent countries. No less than a person than a former Prime Minister of Great Britain, Winston Churchill, described the attitude of the then British government as the ‘biggest escape of human history’. In its urge to get rid of Indian responsibility, the government of Prime Minister Clement Atlee, showed extraordinary haste in relinquishing its responsibilities without ascertaining that the partition of a country of a subcontinental size would involve a huge amount of work. It required taking into consideration all administrative and security aspects so that the two countries could move along their independent journey as good neighbours. Unfortunately, the failure of the British government, both in London and, through its viceroy, in Delhi, left a number of issues unsettled, which the two independent countries have been trying to resolve for the last seven decades. Moreover, with the passage of time, new factors emerged which further complicated the original issues.

Acoustic Scattering from Different Geometries Eigenfunction Mode Matching Technique

In this thesis we solve and compare two tri and penta furcated waveguide problems having rigid and soft lining by using mode matching technique. We also study the phenomenon of extraordinary acoustic transmission (EAT) in Helmholtz resonator. It is shown that combination of a single propagating mode and symmetry orthogonal to direction of propagation leads to EAT. This is accomplished by decomposing the problem using symmetry, the Blaschke product and the properties of functions of a single complex variable which have modulus one on the real axis. A detailed numerical study has been presented to analyze reflection and transmission behaviour to probe the acoustic radiated energy. These results can be used in noise reduction devices and theory of acoustics.
