The dock problem revisited
The dock problem (cf. [2], [4, 5]), which is that of understanding the scattering of surface water waves by a thin semi-infinite rigid plate floating on the free surface of water of infinite depth, gives rise to the following mixed boundary value problem, involving Laplace’s equation in two dimensions, with (x, y) representing the rectangular Cartesian coordinates, assuming linearised theory of...
متن کاملThe finite dock problem
The scattering of water waves by a dock of finite width and infinite length in water of finite depth is solved using the modified residue calculus technique. The problem is formulated for obliquely incident waves and the case of normal incidence is recovered by taking an appropriate limit. Exciting forces and pitching moments are calculated as well as reflection and transmission coefficients. T...
متن کاملChibby’s function in the dock
A ribonuclease helps the ER get in shape S chwarz and Blower reveal that a calcium-regulated ribonuclease promotes the formation of tubular ER networks. By triggering a wave of intracellular calcium, fertilization induces dramatic changes in the internal organization and protein expression pattern of oocytes. Schwarz and Blower discovered that increased calcium levels activate a ribonuclease ca...
متن کاملElectoral Reform in Bermuda
One of the inheritances of British colonialism in many parts of the world is an electoral system based on that used to elect members of the UK House of Commons, albeit with many slight variations on the basic model of single-member constituencies allocated to the candidates with a plurality of the votes cast. One such country with that inheritance was Bermuda, which intends to shift its system ...
