  • A natural or an artificial harbor can exhibit frequency(or period) dependent water surface oscillations when excited by incident waves. Such oscillations in harbors can cause significant damage to moored ships and adjacent structures. This can also induce undesirable current in harbors. Many previous investigators have studied various aspects of harbor resonance problem. In the percent paper, both a localizes finite element method(LFEM) which is based on the functional constructed by Chen & Mei(1974) and Bai & Yeung(1974) and an integral equation method which was used by Lee(1969) are applied to harbor resonance problem. The present method(LFEM) shows computationally more efficient than the integral equation method. Our test results shows good agreement compared with other results. This enhanced computational efficiency is due to the fact that the present method gives a banded symmetric coefficients matrix and requires much less computational time in the calculation of the influence coefficients matrix than the integral equation method involved with Green's function. To test the present numerical scheme, two models are treated here. The present method(LFEM) can be extended to a fully three dimensional harbor problem with the similar computational advantage.

  • While the technique of In Vitro Fertilization and Embryo Transfer has been proven undoutedly, it is for from reaching a consensus on the legal implication. Legal authority regarding clinical therapeutic In Vitro Fertilization and Embryo Transfer is, for all practical purpose, nonexistant. In this paper, it is discussed existing regulation dealing with In Vitro Fertilization and Embryo Transfer and related areas i.e. the regulation related medical technologies, the use of donor sperm, donor eggs, surrogate uteri, multiple pregnancy, miscarriages, extra embryos, the technique of cryopreservation. The legality of embryo donation, the responsibility for embryo preservation or destruction and the legal status of the embryos are surveyed. Finally the various legal theories that may give rise to physician liability in connection with clinical In Vitro Fertilization are also reviewed.
