There can be few aspects of Indian studies more neglected than that of historical geography. Within this larger area of neglect, urban history occupies a special place. The indifference with which Indian historians have approached the urban heritage of the subcontinent is all the more difficult to understand because to contemporary European visitors, the merchants and other travellers, the towns and cities of Mughal India held a profound fascination. From the time of Tomé Pires and his highly perceptive Suma Oriental down to the end of the eighteenth century, stories of Indian travels and the accompanying descriptions of Mughal urban life continually entertained the popular literary audience. Not all of them understood or reported accurately what they saw. As the Scottish sea captain and country trader, Alexander Hamilton, who had an unrivalled knowledge of the sea ports and the coastal towns of India, pointed out with some candour, one great misfortune which attended the western travellers in India was their ignorance of the local languages. But the manifest contrast between the physical appearance of the European cities and those of Asia provoked some considerable and sensitive analysis of the nature of the urban processes in the two continents. Perhaps the most able and penetrating comments on the Mughal political, economic, and civic order came from the pen of the Dutch merchant, Francisco Pelsaert, and the French physician, François Bernier.

Abstract A non-parametric model for magneto-rheological (MR) dampers is presented. After discussing the merits of parametric and non-parametric models for MR dampers, the test data for a MR damper is used to develop a non-parametric model. The results of the model are compared with the test data to illustrate the accuracy of the model. The comparison shows that the non-parametric model is able to accurately predict the damper force characteristics, including the damper non-linearity and electro-magnetic saturation. It is further shown that the parametric model can be numerically solved more efficiently than the parametric models.

ABSTRACTLactation curves are fitted to data as a preliminary to estimating summary statistics. Two widely quoted curves are atbe-ct (Wood, 1967) and a(1 - e-bt) - ct (Cobby and Le Du, 1978), each of which has three parameters. Restriction to either of these curves imposes limitations on the fit to the data and can result in biased estimation of summary statistics. Alternatively, lactation curves can be generated by the use of a non-parametric method which requires only weak assumptions about the signs of derivatives of the curves. Because the non-parametric curves are more flexible, estimates of summary statistics are less likely to be biased than those based on parametric models. Use of the non-parametric curves is particularly advantageous around the time of peak yield, where the curves of Wood and Cobby and Le Du are known to fit data poorly.
