Combining two or more items and selling them as one good, a practice called bundling, can be a very effective strategy for reducing the costs of producing, marketing, and selling goods. In this paper, we design a system for a shop, to negotiate both the contents and the price of bundles of goods...

For the two-way fixed effects ANOVA, under assumption violations, the present study employs trimmed means and Hall's transformation to correct asymmetry, and an approximate test, such as the Alexander-Govern or Welch-James test, to correct heterogeneity. The unweighted as well as weighted means...

Ray-tracing program SHADOW was used to simulate X-ray propagation in capillaries with cylindrical, tapered and polynomial profiles. The results indicate efficient concentration of X-ray beams by all of these capillaries. The influences on transmission properties from geometry parameters of...

In this paper, we propose a heterogeneous interacting agent model of a sequential monetary production economy. We use a basic dynamic flow model in an interacting agent context. The economy is assumed to be closed. There are three classes of agents: a single homogeneous representative consumer,...

Search tactics are cognitive processes, or decision mechanisms, that organisms use to locate available resources such as food, mates, refugia, and high-quality habitats. However, our knowledge of the actual tactics that animals use while searching for resources is limited, and very little...
