This paper explores some of the design choices made in casting DocBook from an XML DTD to a RELAX NG Grammar. It highlights specific areas where RELAX NG provides features and benefits to schemas designed for direct authorship by human beings, particularly schemas with many mixed content elements. One potential direction for the evolution of DocBook is presented. Extreme DocBook Table of

This paper proposes a new perspective in the enhancement of the closed-loop tracking performance by using the first-order hold (FOH) sensing technique. Firstly, the literature review and fundamentals of the FOH are outlined. Secondly, the performance of the most commonly used zero-order hold (ZOH) and that of the FOH are compared. Lastly, the detailed implementation of the FOH on a pendulum tra...

This note generalizes analytical relationships among activity variables of DEA models previously derived by Boussemart, Briec and Leleu (2007). We relax the asumption of constant returns to scale by showing that the key results hold under a weaker asumption of homogeneity. We use the notion of α -returns to scale to extend the analysis to strictly increasing and decreasing returns, covering now...

hemoglobin is a tetrameric oxygen transport protein in animal bodies. however, there is a paucity of information regarding differences between alpha and beta subunits of hemoglobin in terms of oxygen affinity. the sequential model of koshland, nemthy and filmer (knf model) has attributed similar affinities to both alpha and beta subunits. the main purpose of the present study is to construct a ...
