σ-sporadic prime ideals and superficial elements

Let $A$ be a Noetherian ring, $I$ be an ideal of $A$ and $sigma$ be a semi-prime operation, different from the identity map on the set of all ideals of $A$. Results of Essan proved that the sets of associated prime ideals of $sigma(I^n)$, which denoted by $Ass(A/sigma(I^n))$, stabilize to $A_{sigma}(I)$. We give some properties of the sets $S^{sigma}_{n}(I)=Ass(A/sigma(I^n))setminus A_{sigma}(I...

A Comprehensive Model for R and D Project Portfolio Selection with Zero-One Linear Goal-Programming (RESEARCH NOTE)

Technology centered organizations must be able to identify promising new products or process improvements at an early stage so that the necessary resources can be allocated to those activities. It is essential to invest in targeted research and development (R and D) projects as opposed to a wide range of ideas so that resources can be focused on successful outcomes. The selection of the most ap...

Limiting Covariance in Markov-renewal Processes

General additive functions called rewards are defined on a "regular" finite-state Markov-renewal process. The asymptotic form of the mean total reward in [0,t] has previously been obtained, and it is known that the total rewards are joint-normally distributed as t -► oo. This paper finds the dominant asymptotic term in the covariance of the total rewetrds as a simple function of the moments of ...
