This paper describes a new empirical watershed model, the prime feature of which is its parsimony. It involves only three free parameters, a characteristic unparalleled by continuous process models able to work on a wide array of catchments. In spite of its crude simplicity, it achieved, on average, worthwhile results on a set of 140 French catchments and overwhelmingly outperformed a linear mo...
We study the Borel summation method. We obtain a general sufficient condition for a given matrix A to have the Borel property. We deduce as corollaries, earlier results obtained by G. Müller and J.D. Hill. Our result is expressed in terms belonging to the theory of Gaussian processes. We show that this result cannot be extended to the study of the Borel summation method on arbitrary dynamical s...
Linear programming is a very important class of problems, both algorithmically and combinatorially. Linear programming has many applications. From an algorithmic point-of-view, the simplex was proposed in the forties (soon after the war, and was motivated by military applications) and, although it has performed very well in practice, is known to run in exponential time in the worst-case. On the...
Shannon’s noiseless coding theorem tells us how compactly we can compress messages in which all letters are drawn independently from an alphabet A and we are given the probability pa of each letter a ∈ A appearing in the message. Shannon’s theorem says that, for random messages with n letters, the expected number of bits we need to transmit is at least nH(p) = −n ∑ a∈A pa log2 pa bits, and ther...
The purpose of this study was to examine the role technological intensity in the choice of compensation policies, and the influence of such policies on market performance and turnover in high and low technological intensity firms. Using a survey of 252 Canadian firms, we show technology intensity has significant influence on compensation policies. A second survey of 128 Canadian organizations s...
If G is undirected, then we say that it has a nowhere-zero Γ flow if the graph admits a nowhere-zero Γ flow after giving an orientation to all the edges. As we saw, if one orientation works then any does, since inverses exist in abelian groups. Definition 2 Let G be an undirected graph. For integer k ≥ 2, a nowhere-zero k-flow φ is an assignment φ : E → {1, . . . , k−1} such that for some orien...
In practice we frequently encounter systems which are most appropriately represented by discontinuous ordinary differential equations. Such equations are investigated qualitatively by Filippov [Z], He [3], Michel and Porter [S, 61, and others. Many such systems often are complex and of a very large scale. It is possible to view such systems as consisting of several simpler subsystems which when...

This research documents an intriguing empirical phenomenon whereby states of relaxation increase the monetary valuation of products. This phenomenon is demonstrated in six experiments involving two different methods of inducing relaxation, a large number of products of different types, and various methods of assessing monetary valuation. In all six experiments participants who were put into a r...
