The paper addresses the problem of flexible Workflow Management Systems (WFMS) in distributed environment. Concerning the serious deficiency of flexibility in the current workflow systems, we describe how our FlexFlow workflow system meets the requirements of interoperability, scalability, flexibility, dependability and adaptability. With an additional route engine, the execution path will be adjusted dynamically according to the execution conditions so as to improve the flexibility and dependability of the system. A dynamic register mechanism of domain engines is introduced to improve the scalability and adaptability of the system. We describe functionalities, collaborations and process state diagrams of our system. The system is general purpose and open: it has been designed and implemented as a set of CORBA services. The system serves as an example of the use of middleware technologies to provide a fault-tolerant execution environment for long running distributed applications. The system also provides a mechanism for communication of distributed components in order to support inter-organizational WFMS. © (2012) Trans Tech Publications, Switzerland. Source

CNC roll grinder, which must be carried out comprehensive analysis in the repair process, is a complex mechanical and electrical integration products. Especially in terms of the mechanical behaviors of the machine tool, performance failure analysis must be carefully. In this paper, the KISC HERKULES grinder analysis of existing fault and improve maintenance. Examples are presented below, for the repair technology. © (2013) Trans Tech Publications, Switzerland.

This work studies the reconstruction of high-speed roll grinder for sculptured surfaces with high feed rates. Experiments and predictions were focused on representative surfaces of dies and molds, whose geometric complexity and complexity distribution were modified parametrically. CNC programs for machining these surfaces were executed in a HERKULES HSF2CNC machining center with a SIEMENS 840D controller, with different levels of programmed feed rate. Discrepancies between programmed and actual feed rates were evaluated. A mechanistic approach for roll grinder in high-speed milling of sculptured surfaces is proposed. The mechanistic model construction is based on: (a) the frequency distribution of linear interpolation path lengths in the CNC program and (b) a characterization of the machine tool for brisk and smooth movements. Two case studies were used to demonstrate the effectiveness of the proposed approach. The reconstruction model is capable of the manufacturing. © (2013) Trans Tech Publications, Switzerland. Source

In this paper, a design issue related to the multi-agent based industrial intelligent monitor processing system (IIMPS) in distributed substations is proposed. Multiagent-oriented programming might be the new trend of software programming after object-oriented programming. Multagentoriented approach uses a higher-level point of view to see the problems. We comment on the characteristics of industrial monitor problems and claim that the multi-agent system (MAS) is a good choice to solve problems with these characteristics. The proposed multi-agent based IIMPS is able to analyze industrial all real messages to assist human operators in identifying associated events. A prototype MAS with JAVA-based GUI used to integrate the existing SCADA system and as the user interface for operators to perform will be discussed in the paper. © (2012) Trans Tech Publications, Switzerland.

We calculate inclusive light vector mesons (ρ, ω, and φ) production in relativistic heavy ion collisions based on the idea of gluon saturation in the color glass condensate (CGC) framework. At high energies, the value of saturation momentum becomes larger than the Quantum Chromodynamics (QCD) confinement scale ΛQCD, which implies that αs(Qs) 蠐 1. Using the relativistic kinetic theory, we derive the production rate for the light vector mesons produced by gluon-gluon fusion in the kT-factorization approach. The numerical results indicate that the light vector mesons from the color glass condensate become prominent in p-p, p-Pb, and Pb-Pb collisions at Large Hadron Collider (LHC) energies. © 2015 Chinese Physical Society and IOP Publishing Ltd.
