For decades, companies have been trying to develop and deploy predictive maintenance and prognostics technologies with ad hoc and trial-and-error approaches. These efforts have resulted in limited success, due to the fact that it lacks a systematic approach in deploying the right prognostics tools for the right applications. The presentation will introduce the intelligent maintenance systems methodology as well as advanced decision support tools for product life cycle management and maintenance scheduling. Special emphasis on the use of toolbox of prognostics algorithms to convert machine condition data to useful information for real-time decision making and closed-loop product life cycle system will be examined. A number of case studies will be used to demonstrate the lessons learned from industry testbeds, including Toyota, GM, Komatsu, P&G, GE Aviation, etc. In addition, trends on service design using Dominant Innovation tools will be presented with case studies.

This article puts forward a pattern format for use in the safety critical control domains where adaptable components are part of the control software. The pattern format may be seen as a first step towards establishing a pattern language uniting three interests. The first interest is related to the objective of providing the compre-hensibility and usability found in design patterns with respect to communication of solutions to problems that may be solved by means of adaptive control. The second interest is related to the need to make explicit the requirements to be satisfied in order to facilitate instantiation of a design in different safety critical contexts. The third interest is related to the need to provide argumentation for risk being satisfactory reduced. The pattern format supports not only documentation of a technical solution to a recurring problem, but also documentation of the requirements that must be satisfied when instantiating a design in different contexts as well as solutions for how the safety property may be demonstrated.
On-line determination of the basic frequency of an unknown periodic signal with an arbitrary waveform is crucial in imitating and performing rhythmic tasks with robots. We present a novel method to determine the basic...

This paper deals with the analysis for two types of elitist variant proposed for the DASA algorithm. It is usual for the genetic algorithms to keep the best solution found in the population used from next generation. Another way to insert elitist behaviour in algorithms that construct solution is to use the most attractive components in order to obtain god quality solution, and may be the optimal ones. Based on particularities of ant colony based metaheuristics these two types of elitist behaviour were successfully applied to DASA algorithm. In this paper the efficiency of the proposed elitist variants of DASA algorithms is analyzed using experimental results. The analysis is applied to six benchmark functions from the class of high-dimensional real-parameter optimization problems.

In the last few years biometric data acquisition and processing systems for person identity verification and / or identification started to be increasingly used. This is done both in military applications for person identification in military operations and war theatres, but also in civilian applications for personal identity verification, accounting systems, etc. Depending on the organization policy, such systems must be secured and customized, for application enhancement, and to fulfil the organization requirements. Such systems which allow customization and enhancement are not available for source code modification and feature enhancement. This paper presents a software image processing development environment IPDE based on vision tools, which is able to run vision projects but also allow the user to develop stand alone applications in a short amount of time, applications which are based on customized vision tools. The IPDE is used to exemplify the process of creating an iris recognition application where a set of vision tools were used in order develop a customized iris image segmentation routine. The paper is structured on three chapters presenting the IPDE architecture, the vision tools, the application development stages, and ends with some experimental data and conclusions.
