SHIFT OPERATOR FOR PERIODICALLY CORRELATED PROCESSES

The existence of shift for periodically correlated processes and its boundedness are investigated. Spectral criteria for these non-stationary processes to have such shifts are obtained.

Hedging of Options in Jump-Diffusion Markets with Correlated Assets

We consider the hedging problem in a jump-diffusion market with correlated assets. For this purpose, we employ the locally risk-minimizing approach and obtain the hedging portfolio as a solution of a multidimensional system of linear equations. ‎This system shows that in a continuous market, independence and correlation assumptions of assets lead to the same locally risk-minimizing portfolio. ‎...

Blind Separation of Jointly Stationary Correlated Sources

The separation of unobserved sources from mixed observed data is a fundamental signal processing problem. Most of the proposed techniques for solving this problem rely on independence or at least uncorrelation assumption for source signals. This paper introduces a technique for cases that source signals are correlated with each other. The method uses Wold decomposition principle for extracting ...

Moral status of accidents.

No one is naive enough to expect that all moral beliefs are universal. Today, some countries legally beat and imprison homosexuals, and others recognize gay marriage; in some places, killing a bull is a sport, and, in others, it is an abomination; in some places, corporal punishment is the obligation of a responsible parent and, in others, grounds for forced removal. Indeed, the burden of proof...
