These interests potentially conflict, and the decision-makers for the firm must trade off one concern versus another. Here we examine the efficiency of insurance… (More)
In Data Envelopment Analysis (DEA), identification of the Pareto-efficient frontier of an empirical production possibility set is a prerequisite step toward determining rates of change of outputs with changes in inputs along its piecewise linear facets. These rates of change, which will be different on different facets, have important economic and… (More)
Mobile commerce (m-commerce) is an increasingly important component of the consumer and business marketplace which, according to ABI Research, is expected to grow to $119 billion in 2015. With the large number of users and the prevalence of smart phones, m-commerce presents an opportunity for businesses to expand their market (and the potential threat to… (More)
Ex = (I + y / t) (l +. r y / : ') El0 = (1 + ! / / Z) (l + .r2y/:3) all R-multiples of Es. The error positions in this case are (j. 1. l) , In general, when decoding an error relative to an algebraic geometric code C*(D. 7rtP), there is a vector space S (g) l of error-locator functions of dimension Z(m)-e. Most algorithms settle for any element of this… (More)
