A multi-name credit derivative is a security tied to an underlying portfolio of corporate bonds or other credit-sensitive securities. It enables investors to buy and sell protection against the default losses in the portfolio. The value of a multiname derivative depends on the distribution of portfolio loss at multiple horizons. Intensity-based models of the loss point process that are specifie...

Sequential decision theory formally solves the problem of rational agents in uncertain worlds if the true environmental prior probability distribution is known. Solomonoff’s theory of universal induction formally solves the problem of sequence prediction for unknown prior distribution. We combine both ideas and get a parameter-free theory of universal Artificial Intelligence. We give strong arg...

In this paper, the problem of reducing a given LTI system into a left or right invertible one is addressed and solved with the standard tools of the geometric control theory. First, it will be shown how an LTI system can be turned into a left invertible system, thus preserving key system properties like stabilizability, phase minimality, right invertibility, relative degree and infinite zero st...

In this paper two external schema generation algorithms are presented. These algorithms are defined in the framework of the new external schema definition methodology for OODBs put forward in (Samos, 1995); they generate an external schema from a set of classes selected from those existing in an external schema definition repository. Their main characteristic is that they avoid the generation o...

down syndrome is one of the most common causes of mental retardation observed in approximately 1/700 live birth. the use of two or more str markers related to chromosome 21 facilitates the diagnosis of down syndrome within about six hours from the collection of the samples. this is the first study has been performed in iranian population to assess the diagnostic value of using small tandem repe...
