This paper proposes a systematic method of creation and application of a virtual factory. Basic definition of a of virtual factory is first given , followed by its foundation principles and architectural overview, and then a systematic method based on object technologies is proposed to create the virtual factory. Specially, for a real manufacturing environment, a corresponding virtual factory c...

Ad hoc communication applications, such as computer-facilitated collaboration, have become possible with the rapid advancements in portable computing and ad hoc wireless networking. Ad hoc communication solutions require a balance between private communications and access to corporate networked services in order to succeed. In this paper, we discuss and offer some approaches in integrating ad h...

Reset controllers are linear controllers that reset some of their states to zero when their input is zero. We are interested in their feedback connection with linear plants, and in this paper we establish fundamental closed-loop properties. This paper considers more general reset structures than previously considered, allowing for higher-order controllers and partial-state resetting. It gives a...

the most important factor in evaluating dental health is dmft (decayed, missing, filled, teeth). this research was conducted to compare dmft index in the workers of sweets and cable factories of shahrood (moghan), a small city near 300 km east of tehran. all the 127 production line workers of cable factory and 124 workers of sweets factory who had the predetermined criteria were selected. a que...

This document describes some of the technological aspects of a project devoted to the creation of a factory for language resources. The project’s objectives are explained, as well as the idea to create a distributed infrastructure of web services. This document focuses on two main topics of the factory: (1) the technological approaches chosen to develop the factory, i.e. software, protocols, se...

OBJECTIVES To evaluate sensitization and acute respiratory health effects in inhabitants living in the vicinity of a factory producing soy oil. METHODS Two panels of potential responders were created on the basis of a response to a short screening questionnaire sent to random samples of 1,000 exposed and 1,000 non-exposed individuals living around the factory and a control area. Individuals r...

heavy metals, e.g. cd and pb emit and release into the environment during cement production and are deposited into soils. this research was carried out to determine the concentration and spatial distribution of trace elements in top soils around the kurdistan cement factory, west of iran in order to evaluate the effect of cement factory on the environment. twenty-four soil samples were collecte...

The digital factory concept is an integrated approach to enhance the product and production engineering processes and simulation is a key technology in digital factory concepts. Different types of simulation can be applied in virtual models on various planning levels and stages to improve the product and process planning. In an advanced stage simulation can be used in the digital factory concep...

The uncertainty of the theoretical prediction of the B̄ → Xsγ branching ratio at NLL level is dominated by the charm mass renormalization scheme ambiguity. In this paper we calculate those NNLL terms which are related to the renormalization of mc, in order to get an estimate of the corresponding uncertainty at the NNLL level. We find that these terms significantly reduce (by typically a factor o...

This paper describes the integration of an experience factory in a modelbased risk analysis framework called CORAS. CORAS aims at developing a new model-based risk analysis framework for security critical application. The framework’s cornerstone of combining methods for risk analysis of critical systems and semiformal modelling methods in a tool-supported environment targeting openness and inte...
