| We analyze a slotted DSCDMA system to guarantee QoS requirements for realtime tra c [1]. A Markovian analysis for realtime tra c and an equilibrium point analysis (EPA) for non-realtime tra c are applied in a heterogeneous environment. Packet losses for realtime tra c, delay times for non-realtime tra c, and wireless link utilization are derived.

Aiming at the redundancy problem of association rules in the mining process of mining association rules, a kind of shortest antecedent set algorithm (SASA) for mining association rules is proposed in this paper, and the algorithm is supported by the set-enumeration tree structure. The proposed algorithm is able to record a kind of subset for association rules without any information loss, and t...

the present article studies one of the new methods of story narration which reviews the constant stream of thoughts and feelings inside the minds of the characters of the story. one of the basic objectives of applying this technique is having freedom in the regular elements of theme and plot. instead of codes the story is based on tangible and touchable realities so that the reader will be able...

The concept of Lucky k-polynomials and in particular Lucky χ-polynomials was recently introduced. This paper introduces Stirling number of the fourth kind and Lucky partitions of a finite set in order to determine either the Lucky k- or Lucky χ-polynomial of a graph. The integer partitions influence Stirling partitions of the second kind.

Innovations that reduce costs of transport from rural locations may also reduce transport costs to rural areas. As transport costs fall, producers can afford to concentrate and achieve economies of scale. This paper explains an initially negative, but ultimately positive, relationship between reductions in transport costs and rural development. A two-region general equilibrium model with firm a...

Models of macroeconomic learning are populated by agents who possess a great deal of knowledge of the “true” structure of the economy, and yet ignore the impact of their own learning on that structure; they may learn about an equilibrium, but they do not learn within it. An alternative learning model is presented where agents’ decisions are informed by hypotheses they hold regarding the economy...

A conventional wisdom in economics is that a model dealing frictionless markets with a large number of agents always yields a Walrasian outcome. In this paper we assess the above argument in a dynamic framework by modeling centralized auction markets, and show that in such markets the outcomes are not necessarily Walrasian; the set of stationary equilibria in our model is a continuum which incl...
