Declining gauging infrastructure and fractious water politics have decreased available information about river flows globally. Remote sensing and water balance modeling are frequently cited as potential solutions, but these techniques largely rely on these same in-decline gauge data to make accurate discharge estimates. A different approach is therefore needed, and we here combine remotely sens...

For decades Africa has been losing billions of dollars every year as a result illicit financial flows. When export and import figures are tampered with this the tendency to erode tax base. It is common cause that in large percentage state revenue emanates from taxation. The consequence base erosion government less revenue. With revenue, increasingly unable provide social services. consequences ...

[1] Granular mass flows of rock fragments are studied in the lab by means of a high-speed video camera at 2000 frames per second. These granular flows are generated using beds of pumice fragments positioned on a rough rotating disk, whose angular velocity is controlled by a motor. The experimental apparatus allows an understanding of the arrangement of the particles in granular mass flows with ...

This paper addresses the problem of locating base stations in a certain area which is highly populated by mobile stations; each mobile station is assumed to select the closest base station. Base stations are modeled by players who choose their best location for maximizing their uplink throughput. The approach of this paper is to make some simplifying assumptions in order to get interpretable an...

In complete transposition of the great vessels the pulmonary and systemic circulations exist as two separate circuits. Although the pulmonary and the systemic blood flows may vary widely, the effective pulmonary blood flow is often small (Shaher, 1964). While the acid-base balance in the systemic circuit has been studied by several workers (Sunico, Harned, and Ordway, 1960; Gootman, Scarpelli, ...

Modelling is the art of taking a real-world situation and constructing some mathematics to describe it. It’s an art rather than a science, because it involves choices that can not be rationally justified. Personal preferences are important, and ‘taste’ plays a major role. Having said that, some choices are more rational than others. And we often also need to explain our choices to ourselves and...
