Expert Systems (ESs) are problem solving computer packages that use expert knowledge to attain a high level of performance that normally would require years of special education and training (Hays-Roth et al., 1983; Waterman, 1986; Turban, 1990), and are a special type of Management Information Systems (MISs) to provide information to support decision-making (Davis and Olson, 1985). The name ES...

DNA sequence alignment is one of the most important operations of computational biology. In 1981, Smith and Waterman developed a method for sequences local alignment. Due to its computational power and memory requirements, various heuristics have been developed to reduce execution time at the expense of a loss of accuracy in the result. This is why heuristics do not ensure that the best alignme...

We determine the distribution of duration in the gambler’s ruin problem given that one specific player wins. In this version we allow ties in the single games. We present a unified approach which uses generating functions to prove and extend some results that were obtained in [Frederick Stern, Conditional expectation of the duration in the classical ruin problem, Math. Mag. 48 (4) (1975) 200–20...

The purpose of this study was to detect latent periodicity in the presence of deletions or insertions in the analyzed data, when the points of deletions or insertions are unknown. A mathematical method was developed to search for periodicity in the numerical series, using dynamic programming and random matrices. The developed method was applied to search for periodicity in the Euro/Dollar (Eu/$...

We analyze the impact of the ownership structure of cable television …rms on the incentives to upgrade the cable networks to o¤er telecommunication services. First, we show that dual ownership of a local telephone network and a cable network, compared with separate ownership, may increase or decrease incentives to invest in upgrading the cable television network. Coordination economies bene…t d...

1 Waterman & Choi (2011) sketches the economic model of this paper in narrative form. Abstract An important aspect of the network neutrality debate is whether government should regulate only Internet service provider (ISP) transactions with upstream content providers, or to also regulate transactions with consumers. A simple model shows that a non-discrimination access rule, applied only to dis...

One of the biggest challenges confronting the bioinformatics community is fast and accurate sequence alignment. The Smith-Waterman algorithm (SWA) is one of the several algorithms used in addressing some of these challenges. Though very sensitive in doing sequence alignment, SWA is not used in real life applications due to the computational cost associated with the software implementation. Heur...

MOTIVATION The analyses of the increasing number of genome sequences requires shortcuts for the detection of orthologs, such as Reciprocal Best Hits (RBH), where orthologs are assumed if two genes each in a different genome find each other as the best hit in the other genome. Two BLAST options seem to affect alignment scores the most, and thus the choice of a best hit: the filtering of low info...
