The flexibility and reusability afforded by service-oriented architectures seems to be of singular applicability to the management of virtual enterprises. In this paper we describe the architecture of the SOAVE platform: a Service-Oriented Architecture for Virtual Enterprises. The platform provides the members of a networked community with a set of tools with which they can collaborate on the p...

It is proposed that certain techniques from arithmetic algebraic geometry provide a framework which is useful to formulate a direct and intrinsic link between the geometry of Calabi-Yau manifolds and the underlying conformal field theory. Specifically it is pointed out how the algebraic number field determined by the fusion rules of the conformal field theory can be derived from the number theo...

A b st r act . The relationship between "learning" in ad aptive layered networks and the fit ting of data wit h high dimensional surfaces is discussed . T his leads natu rally to a picture of "generalization" in terms of interp olation between known data points and suggests a rat ional approach to th e theory of such networks. A class of adaptive networks is identified which makes the inte rpo ...

Each of the basic operative methods for Hirschsprung's disease (the rectosigmoidectomy developed by Swenson, the retrorectal transanal approach developed by Duhamel, and the endorectal procedure developed by Soave and modified by Denda and Boley) can give good results. A protective colostomy should be routine. If only an occasional case is prevented from progressing to incontinence or septicemi...

A central issue in the equation of state (EoS) development is to describe accurately fluid density and thus other thermodynamic properties based on it. This study attempts investigate modeling high-pressure mixtures, particularly related reservoir fluids, by cubic non-cubic EoS. large database binary mixtures petroleum fluids was established used compare some typical EoS, including SRK, PR, PC-...

Jerami padi adalah salah satu limbah pertanian yang melimpah di Indonesia dapat digunakan sebagai sumber lignoselulosa untuk produksi biogas. Salah metode meningkatkan biogas dengan menambahkan cairan rumen dan kotoran sapi. Penelitian ini membandingkan pada sapi (JP-R) campuran (JP-RKS). Percobaan dilakukan dalam reaktor <em>batch</em> anaerob selama 30 hari volume kerja 3,6 L suhu...

OBJECTIVES To provide a simple myomectomy technique for low-segment Hirschsprung disease and evaluate the efficacy of the new modification. DESIGN Case series of 19 patients followed up for 12 to 56 months (mean, 39.1 months). SETTING Tanta University Hospital, Tanta, Egypt. PARTICIPANTS Nineteen patients aged 4 months to 10 years complaining of chronic constipation, with radiological and...
