The Duty to Obey the Law

Under what conditions, if any, do those the law addresses have a moral duty or obligation to obey it simply because it is the law? Political and legal theorists since Plato have developed a wide range of answers to this question, as well as numerous objections to those answers. This essay aims primarily to provide the newcomer with a point of entry into the debate over the existence and grounds...

Finite-state Markov Chains Obey Benford's Law

A sequence ofreal numbers (xn) is Benford if the significands, i.e., the fraction parts in the floating-point representation of (x ), are distributed logarithmically. Similarly, a discrete-time irreducible and aperiodic fi­ n nite-state Markov chain with transition probability matrix P and limiting matrix P' is Benford if every com­ ponent of both sequences of matrices (pn P') and (pn+1 pn) is ...

The Obligation to Obey: Revision and Tradition

Generating network topologies that obey power laws

Recent studies have shown that Internet graphs and other network systems follow power-laws. Do artiicial network topologies commonly used in network simulation studies obey these power-laws? In this paper we show that current topology generators do not obey all of the power-laws, and we present two new topology generators that do. Finally, we re-evaluate a multicast study to demonstrate the imp...

On Single Compartment Pharmacokinetic Model Systems that Obey Michaelis-Menten Kinetics and Systems that Obey Krebs Cycle Kinetics

The integration of Michaelis-Menten kinetics results in a trancedental equation. The results are not in a form that is readily usable. A more usable form of the model solutions is developed. This was accomplished by using Taylor series expansion of dimensionless concentration u in terms of its derivatives. The infinite series expression for dimensionless concentration is given. It can be seen t...
