The Indian Posts & Telegraphs Department set up this telegraph workshop at Alipore, Calcutta in early 1855 as a repair workshop, and gradually it started production of Telegraph and Telecom equipment. This workshop supplied Telegraph/Telecom materials throughout India (including the territory of Burma prior to 1937). This is one of a set of 45 p...

For the study of complex synthetic and biological molecular systems by computersimulations one is still restricted to simple model systems or to, by far toosmall, time scales. To overcome this problem multiscale techniques are beingdeveloped. However in almost all cases, the regions treated at different level ofresolution are kept fixed and the ...

We report our recent efforts in developing the adaptive perfectly matched layer (PML) method solving the time-harmonic electromagnetic and acoustic scattering problems. The PML parameters such as the thickness of the layer and the absorbing medium property are determined through sharp a posteriori error estimates. Combined with the adaptive ï¬ n...

In the numerical analysis of elliptic PDEs, much attention has been given (quite rightly) to the discretization of the Laplace operator and other second-order Laplace-type operators, e.g., the Hodge--Laplace operator on differential $k$-forms. By comparison, Dirac-type operators have received little attention from the perspective of nume...
