The Rational Unified Process provides a valuable framework for approaching the business of developing software. As a framework, however, it must be adapted to the needs of each project team and their circumstances; it is intended to be applied in a light and agile style, and not adopted as a one-size-fits-all process. This article shares a number of common pitfalls experienced by teams attempti...

We have examined the rational solitons in the Generalized Coupled Mode model for a deep nonlinear Bragg grating. These solitons are the degenerate forms of the ordinary solitons and appear at the transition lines in the parameter plane. A simple formulation is presented for the investigation of the bifurcations induced by detuning the carrier wave frequency. The analysis yields among others the...

The standard model is that word identification in reading is a holistic process, most efficient when words are centered in the visual field. In contrast, rational models of reading predict word identification to be a constructive process, where readers efficiently gather visual information about a word, and may combine visual information about different parts of the word obtained across multipl...

General offset curves are treated in the context of Minkowski geometry, the geometry of the two-dimensional plane, stemming from the consideration of a strictly convex, centrally symmetric given curve as its unit circle. Minkowski geometry permits us to move beyond classical confines and provides us with a framework in which to generalize the notion of Pythagorean-hodograph curves in the case o...

The behavior of ion-exchange chromatography is well understood with respect to changes in ionic strength, pH, resin ligand density, bed height, elution flow rate, and gradient slope. Their relative importance for any specific chromatographic situation varies. When a chromatographic operation utilized to purify a human therapeutic protein is prepared for validation before commercial production, ...

Various modern decision theories seek to capture the intuition behind Keynes‟s conception of evidential weight. Keynes was nevertheless hesitant about the practical relevance of weight in the process of rational decision making because of the „stopping problem‟ of finding a rational principle to decide where to stop the process of acquiring information in forming a probability judgment before m...
