XML is today a standard for manipulating semistructured data. One of widely used industrial solutions, especially for systems with a fairly well defined data structure, is storing XML in a relational database, while XML queries are converted to SQL queries to the underlying relational database. A software product that produces XML “interface” to an underlying relational database commonly requir...

This paper presents a model-driven and integrated approach to variability management, customization and execution of software processes. Our approach is founded on the principles and techniques of software product lines and model-driven engineering. Model-driven engineering provides support to the specification of software processes and their transformation to workflow specifications. Software ...

Melanin is one of the most important factors affecting skin color. Melanogenesis is the bioprocess of melanin production by melanocytes in the skin and hair follicles and is mediated by several enzymes, such as tyrosinase, tyrosinase related protein (TRP)-1, and TRP-2. Convenient enzymatic transformation of the simple phenol pyrogallol with polyphenol oxidase originating from pear to an oxidati...

We have sought to identify candidate substrates for src family protein-tyrosine kinases potentially important for transformation. Transfected NIH/3T3 cells, each overexpressing a normal or activated version of the fyn, fgr, or src translational product, were examined using antibody to phosphotyrosine as a probe. Expression of each cDNA induced similar but distinct patterns of tyrosine phosphory...

An approach for building energy-stable Galerkin reduced order models (ROMs) for linear hyperbolic or incompletely parabolic systems of partial differential equations (PDEs) using continuous projection is developed. This method is an extension of earlier work by the authors specific to the equations of linearized compressible inviscid flow. The key idea is to apply to the PDEs a transformation i...

The need for product customisation is driving industrial companies towards a very large product variety, which a€ects many functions of a company, including the after-sales. Systematic maintenance records of very di€erent product individuals cannot be kept without an abstract view to the population of delivered products. However, the older the product individual, the less systematically recorde...

A well known conjecture in the theory of transformation groups states that if p is a prime and (Z/p) acts freely on a product of k spheres, then r ≤ k. We prove this assertion if p is large compared to the dimension of the product of spheres. The argument builds on tame homotopy theory for non-simply connected spaces.

We study the distribution modulo m of the convergents associated with the d-dimensional Jacobi-Perron algorithm for a.e. real numbers in (0, 1) by proving the ergodicity of a skew product of the Jacobi-Perron transformation; this skew product was initially introdued in [6] for regular continued fractions.

MAXIMUM LIKELIHOOD ESTIMATOR OF Drops out of computation of likelihood ratio. DISTRIBUTION OF CONSTRAINT Under normal errors the Euclidean inner product turns out to be practically normal with variance: CONSTRAINTS Five or more orthogonality relations in the form of the Euclidean inner product determine the absolute conic. Rectifying transformation is obtained by Cholesky decomposition. Active ...

Collaborative product design is nowadays a trend of advanced manufacturing technology. Collaborative product design is a knowledge-intensive activity; knowledge management in collaborative product design has been focused. Existing literatues maily focus on knowledge management systems in collaborative design, other aspects of design activity is rarely paid attention to. The framework of activit...
