This paper describes the development and validation of a computer numerical controller architecture adherent to the standard STEP-NC Part-11 that is associated with the milling process. The STEP-NC controller development is based on the open source driver EMC (Enhanced Machine Controller or LinuxCNC) adherent to the standard RS-274 that originally works with the NC program using codes G/M (G-co...

An Object-Oriented Timed Petri-net (OOTPN) is proposed for modeling agile manufacturing cell (AMC). It consists of four phases: (1) grouping manufacturing resources into classes; (2) constructing general OOTPN block for each manufacturing resource class; (3) defining joint transitions and suitable control decision rules; (4) generating complete OOTPN model for agile manufacturing cell. This OOT...

It is taking place in 4 tertiary hospitals, 3 secondary hospitals and 4 primary health facilities in Beijing, and 2 tertiary hospitals, 2 secondary hospitals and 2 primary health cent...

Knowledge-based persistent archives manage digital objects, information attributes about the digital objects, and the implied knowledge that is needed to understand relationships between the information attributes. This report illustrates the processes used to ingest data, information, and knowledge in the context of the Senate Legislative Activities collection. 1. Preservation Strategies Persi...

This paper proposes a new paradigm called ’distributed dynamic integration’ that attempts to dynamically implement system integration according to different application stages, system modules, and computing modes wherein each process stage possesses several characteristics. The concept, modelling, structure, and strategies of distributed dynamic integration are discussed. To incorporate the con...

Processes are very important for the success within many business fields. They define the proper application of methods, technologies, tools, and company structures in order to reach business goals. Not only manufacturing processes have to be defined from the start point to their end, also other processes like product development processes need a proper description to gain success. For example ...

Surgical simulation for medical education and preoperative planning has attracted more and more attention in recent years and a number of such virtual environments have been developed and validated. However, almost all of them are focusing on simulating the surgical scene and haptic interaction to provide users with freedom to perform surgery in the virtual environment. We propose that critical...

Although business performance has long been theoretically hypothesised to be dependent on the level of underlying Information Technology capability, there is a distinct lack of empirical studies to support this claim. In this paper we discuss preliminary results of ongoing research into the knock-on effects of computer network support to business process performance indicators. Based on a real-...

Agility is increasingly being seen as a prerequisite for continued competitiveness in the changing global marketplace. However, many of the technological and organizational changes required in making the migration to agility are radical and strategic in nature. Attempting to justify many of these pervasive changes is difficult using currently available techniques, especially those which focus s...

The paper describes an extension of PROSPEC, a system to represent enterprises model-based to derive from the “deep” knowledge of the business processes requirements for a Quality Management System. Especially, features demanded by the new ISO 9000:2000 for such systems such as continuos improvement and determination of customer requirements are addressed. The development of the enterprise mode...
