Based on some relationships between modeland relay-based PI/PID tuning, some very simple synthesis procedures are proposed that couple the advantages of model-based methods to the simplicity and clarity of relay experiments. These procedures are fast, as they employ a single relay test, and do not introduce large process upsets. They are also very light from the computational standpoint, thus w...

The use of authoring tools has become a valuable trend for the fast development of Augmented Reality (AR) applications in industrial organizations. However, most of current AR authoring tools are actually programming interfaces that are exclusively suitable for programmers. Moreover, they do not provide advanced visual effects, such as occlusion or object collision detection, to the resulting A...

The ability to specify CP programs in terms of a declarative model and a search procedure is instrumental to the industrial CP successes. Yet, writing search procedures is often difficult for novices or people accustomed to model & run approaches. The viewpoint adopted in this paper argues for the synthesis of a search from the declarative model to exploit the problem instance structures. The i...

Prediction interval is awidely used tool in industrial applications to predict the distribution of future observations. The exact minimum coverage probability and the average coverage probability of the conventional prediction interval for a discrete random variable have not been accurately derived in the literature. In this paper, procedures to compute the exact minimumconfidence levels and th...

Creating 2D and 3D models in CAD and following creation of drawings are standard procedures for constructing in the current industrial practice. Most models of industrially produced machine parts can be made by basic processes of modeling using construction or hybrid methods. Listed procedures are based on input of a basic – primitive body and its shaping using predefined design elements, combi...

The construction of tolerance intervals (TIs) for discrete variables, such as binomial and Poisson variables, has been critical in industrial applications in various sectors, including manufacturing and pharmaceuticals. Inaccurate estimation of coverage probabilities leads to improper construction of tolerance intervals and may lead to serious financial losses for the manufacturers. This articl...

A new calibration method for industrial robot system calibration on a manufacturing floor is presented in this paper. To calibrate the robot system, a laser sensor to measure the distance between robot tool and measurement surface is attached to the robot end-effector and a grid is established in the floor. Given two position command pulses for a robot manipulator and using the position differe...

This paper presents a management process for creating adaptive, real-time security policies within the Six Sigma 6σ framework. A key challenge for the creation of a management process is the integration with models of known Industrial processes. One of the most used industrial process models is Six Sigma which is a business management model wherein customer centric needs are put in perspective ...

Industrial training is an emerging applicative domain for virtual reality. GVT (Generic Virtual Trai-ning) is a platform to create virtual environments for individual training on industrial procedures suchas maintenance procedures. Nevertheless, industrial needs keep on evolving and a new request concernstraining on collaborative procedures. In this thesis, we propose models to exte...

The (001) surfaces of cubic SiC were investigated with ab-initio molecular dynamics simulations. We show that C-terminated surfaces can have different c(2×2) and p(2×1) reconstructions, depending on preparation conditions and thermal treatment, and we suggest experimental probes to identify the various reconstructed geometries. Furthermore we show that Si-terminated surfaces exhibit a p(2×1) re...
