Sommario/riassunto |
|
A Treatise on Money, completed in 1930, was the outcome of six years of intensive work and argument with D. H. Robertson, R. G. Hawtrey and others. As in the Tract on Monetary Reform, the central concerns of the Treatise are the causes and consequences of changes in the value of money and the means of controlling such changes to increase well-being. The analysis is, however, considerably more complex and the applied statistical work much more elaborate. The Treatise has long been of interest amongst economists, as a precursor of the General Theory, as an important discussion of the mechanics of inflationary and deflationary processes and as an important statement of the problems of national autonomy in the international economy. This edition provides a new edition of the original, corrected on the basis of Keynes's correspondence with other economists and translators. It also provides the prefaces to foreign editions. |

Sommario/riassunto |
|
Possibly the greatest change confronting the practitioner and student of remote sensing in the period since the first edition of this text appeared in 1986 has been the enormous improvement in accessibility to image processing technology. Falling hardware and software costs, combined with an increase in functionality through the development of extremely versatile user interfaces, has meant that even the user unskilled in computing now has immediate and ready access to powerful and flexible means for digital image analysis and enhancement. An understanding, at algorithmic level, of the various methods for image processing has become therefore even more important in the past few years to ensure the full capability of digital image processing is utilised. This period has also been a busy one in relation to digital data supply. Several nations have become satellite data gatherers and providers, using both optical and microwave technology. Practitioners and researchers are now faced, therefore, with the need to be able to process imagery from several sensors, together with other forms of spatial data. This has been driven, to an extent, by developments in Geographic Information Systems (GIS) which, in tum, have led to the appearance of newer image processing procedures as adjuncts to more traditional approaches. |
