In this paper we propose a unifying approach to study optimal growth models with bounded or unbounded returns (above/below). We prove existence of optimal solutions. We prove also, without using contraction method, that the Value function is the unique solution to the Bellman equation in some classes of functions. The value function can be obtained by the usual algorithm defined by the operator...

This correspondence describes a method for nonlinear filtering based on an adaptive observer, which guarantees the local stability of the linearised error system. Filter gain selection is by use of a fake algebraic Riccati equation. The design procedure attempts to produce a stable filter at the expense of optimality. This contrasts with the extended Kalman filter (EKF) which attempts to preser...

In this paper we propose the use of preferred outcome distributions as a new method to elicit individuals’ value and probability weighting functions in decisions under risk. Extant approaches for the elicitation of these two key ingredients of individuals’ risk attitude typically rely on a long, chained sequence of lottery choices. In contrast, preferred outcome distributions can be elicited th...

The market is a place where supply and demand meet. Buying selling can be done without the presence of goods (on stock exchanges other markets), even direct contact between buyers sellers. according to catalog, by phone, fax, internet, etc. Therefore, defined as constant organized form bringing into with for services. At same time, mechanism that regulates relations sellers in conditions which ...

The problem of query by fax (QBF) and by other low quality images for art image retrieval is introduced. A reliable solution to the problem, the slow QBF algorithm, is presented but it is too slow for fast interactive retrieval situations. It is used as a yardstick for assessing the quality of a much faster technique, the fast QBF algorithm, based on the pyramid-structured wavelet transform (PW...

Consider the Cauchy problem for the nonlinear hyperbolic-parabolic equation: (*) ut + 1 2 a · ∇xu = ∆u+ for t > 0, where a is a constant vector and u+ = max{u, 0}. The equation is hyperbolic in the region [u < 0] and parabolic in the region [u > 0]. It is shown that entropy solutions to (*), that grow at most linearly as |x| → ∞, are stable in a weighted L(IR ) space, which implies that the sol...
