Modeling the series of (n×2) Si-rich reconstructions of β–SiC(001): a prospective atomic wire? Abstract We perform ab initio plane wave supercell density functional calculations on three candidate models of the (3×2) reconstruction of the β–SiC(001) surface. We find that the two-adlayer asymmetric-dimer model (TAADM) is unambiguously favored for all reasonable values of Si chemical potential. W...

operator's role in industrial control centers takes place in time, which is one of the most important determinants of whether an expected action is going to be successful or not. in certain situations, due to the complex nature of the work, the existing interfaces and already prepared procedures do not meet the dynamic requirements of operator's cognitive demands, making the control tasks unnec...

Since the industrial revolution the world has seen an ever increasing proliferation of production facilities and with it a steady increase in workplace accidents and fatalities. The field of safety management was borne out of the need to curtail the extremely high human and commercial costs of these incidents. Not surprisingly in the dawn of the industrial age, the initial port of call was engi...

We present a flexible framework for multimodal engineering applications using augmented reality. Our goal is to simplify the configuration procedures and to provide a higher grade of flexibility in multimodal interfaces. The system architecture is based on an extensible plug-in approach. A specific component has been designed to manage and synchronize the different multimodal inputs. A configur...

The paper describes the use of data analysis techniques in the computer-vision inspection of industrial workpieces. Computer-vision inspection aims at accomplishing quality veriication of fabricated parts by means of automated visual procedures. Gathering the visual information into models proves a critical task, especially when subjective judgement is involved in quality veriication. In this w...

The purpose of this paper is to describe how discrete event simulation should be used as a tool for continuous process verification in industrial system development. Results include a specification of the working procedures to be used in each life cycle phase of a development project, as well as a definition of the areas where efforts are needed in the future. The approach assures continuous ve...

To assess and plan future risk-analysis research projects, 275 documents describing methods and tools for assessing the risks associated with industrial machines or with other sectors such as the military, and the nuclear and aeronautics industries, etc., were collected. These documents were in the format of published books or papers, standards, technical guides and company procedures collected...

Maintenance and diagnosis of complex systems are common activities in the industrial world. Technological advances have led to a continuously increasing complexity of industrial systems. This complexity, which is due to an increasing number of components reduces in turn the reliability of plants. Therefore, fault diagnosis is becoming a growing field of interest. But fault diagnosis relies on s...
