An analysis is made of the runtime of a previously published algorithm for polynomial composition. Two new, more eecient algorithms are presented. One of these algorithms is optimal, while the other algorithm is numerically more stable than the optimal one. Additionally, as a generalization of polynomial composition, we show how to compose a multiaane function with a set of polynomials as an ex...

The fatty acid compositions of the intracellular organelles of rat liver, separated by differential centrifuging, and the composition of the rat-liver lipids, have been described by Getz & Bartley (1961) and Getz, Bartley, Stirpe, Notton & Renshaw (1961). This paper describes the lipid composition of the mitochondria, fluffy layer and microsomes isolated from rat liver. A similar study has rece...

The nucleotide sequence of the nrdA gene of Escherichia coli. coding for the large subunit of ribonucleotide reductase, was originally published by Carlson et al. (1). However, the published nucleotide sequence of the nrdA gene is afflicted with scattered errors leading to stretches of frame-shifts, which have severe consequences for the deduced protein sequence. The difference in amino acid co...

Web services have received much interest due to their potential to design and build complex inter-enterprise business applications. A particular interest concerns dynamic Web services composition that offers the opportunity for creating new Web services at runtime from those already published. In this paper we focus on mismatches occurring during dynamic composition of Web services. These misma...

PURPOSE/OBJECTIVES To examine the research literature regarding the effects of exercise on body weight and composition in breast cancer survivors. DATA SOURCES Primary studies in English published from 1989-2004, located through electronic databases, hand searches, and personal contacts. DATA SYNTHESIS Of 1,314 studies screened, 14 met all inclusion criteria. Body weight and composition gen...

In order to provide a rigorous and sound foundation for formal reasoning about Web services, algebraic modeling is one of the important techniques used as is witnessed from the Web service literature. However, the algebraic modeling approach for Web services (Web service algebra) is still in its infancy. To further facilitate the algebraic modeling of Web services, in this paper, we propose a c...

Service Oriented Architectures enable a multitude of Web services to provide loosely coupled and interoperable services at different Quality of Service level in the recent few years. Dynamic Web services composition offers the opportunity for creating new web services at runtime from those already published in UDDI registry. However, this composition requires necessarily quantifying criteria fo...

The Kalina cycle is believed to be one of the most promising technologies for power generation from low temperature heat sources such as geothermal energy. So far, most Kalina cycle power plants are designed with a working fluid mixture having a fixed composition, and thus normally operate at a fixed condensing temperature. However, the ambient temperature (i.e., heat sink) varies over a large ...

BACKGROUND There is a need for a practical, inexpensive method to assess body composition in obese adolescents. This study aimed to 1) compare body composition parameters estimated by a stand-on, multi-frequency bioelectrical impendence (BIA) device, using a) the manufacturers' equations, and b) published and derived equations with body composition measured by dual-energy x-ray absorptiometry (...
