CONSTRAINTS DRIVEN SUBSCRIPTION USING CONFIDENCE INTERVAL MODEL

In the context of intelligent instrument network, i.e. intelligent sensors and actuators, the user or the designer has to manipulate variable network functions. Service model allows the designer to formalize and manipulate information access. Service model also permits to, check, control and react from instrument data and this approach is web-enable. Producer-Consumer pattern facilitates design and intelligent instrument networking. The connection between producer and consumer can be checked (i.e. type of data) and filtered (condition of sending). We propose to extend the producerconsumer approach using service model for variable subscription service where conditions of subscription constraint could be expressed. We consider interval confidence model of data and several consumers to produce the event or data to be subscribed. A prototype is presented to illustrate and validate the approach on the OSGi platform.

DESIGNING WIRELESS INTRUMENTATION SYSTEM WITH THE DIAMOND METHOD

Designing wireless instrumentation systems requires to work with two levels: the individual level (the sensors) versus the social level (the whole system). We introduce the DIAMOND method which allows to design open embedded complex systems using a multiagent approach.

NOVEL APPROACH TO THE COMPUTER-AIDED MODELLING OF MEASUREMENT PROCESSES FOR UNCERTAINTY ESTIMATION

The aim of this paper is to present a methodology to the modelling of measurement processes for uncertainty estimation. According to the “Procedure for the Uncertainty Management” (PUMA) described in the supplement of ISO 14253-1 an iterative course of action is derived. In this connection the efficiency of modelling is considered additionally. The trail version of the novel application software “Model Assistant”, developed within the cooperative research project MST-UNCERT, is used for graphical modelling. A practical stepwise procedure for efficiency modelling has been derived and exemplary applied from this concept.

DESIGN AND OPTIMISATION OF DEPENDABLE MEASUREMENT SYSTEMS

This paper deals with the use of a structural modelling in order to optimise the cost of a measurement system with dependability constraints. The aim of the proposed method is to determine the sensor placement that tolerates a given number of failures with the lowest cost. A structural model is used. It describes the links between the physical quantities and is employed in order to determine the potential analytical redundancies. With that, the optimisation problem becomes an integer linear programming (ILP) problem whose resolution provides the best reliable and lowest-cost system.

OPTIMAL MEASUREMENT SCHEDULING AND DESIGN WITH DYNAMIC PROGRAMMING

We shall present approaches to optimize the design of a measurement system and schedule dynamically a versatile measurement resource. The analysis is based on expressing the system management task as a dynamic programming problem in which the system state is partially observable. We shall review the well-known linearquadratic-Gaussian case, and discuss and give examples solutions of discrete state systems. Furthermore, we discuss on approximate dynamic programming methods to solve such problems in practice.

EDUCATION AND COMPETENCY EVALUATION SYSTEM OF METROLOGY PRACTITIONERS IN LITHUANIA

Metrology practitioners in Lithuania are taught, trained following the program adopted in 1995 and improved in 2000. A huge amount of information related to various aspects of the program has been collected since the beginning. Continuous analysis of the program directly supports its future improvement and long-term goals.

“MEASUREMENT SCIENCE” AND EDUCATION TO CULTIVATE SCIENTIFIC BASIC KNOWLEDGE OF PEOPLE

We had already expressed the importance of “Measurement Science” .on the education to rise up the scientific sense for the people live in the society carried on natural science, technique and information. It is the liberty to apply how “Science” to the Education, an answer is in this paper. And we had reported the contents by some papers. This paper suggests the usefulness of application of “Measurement Science” for the stage 1 and stage 2 education (Compulsory Education) and the stage 3 education (Semi-Compulsory Education), when classify National Education in 5 stages.

A NEW APPROACH IN SOFTWARE EDUCATION IN METROLOGY AND QUALITY ASSURANCE – AN EMPIRICAL STUDY

Future engineers working in the field of metrology and quality assurance will require more profound software knowledge than today. In addition to that it is often claimed that measurement science is not that close as it should be to daily practice. The following article describes a new approach in education developed and applied at the Technische Universität Ilmenau. Based on a SQL database server and a Microsoft Office client students are enabled to develop customised software solutions to problems of practical relevance without having any specific knowledge in advance. Furthermore the paper details which difficulties occurred most often. It is also discussed to what extent the developed software solutions are likely to be deployed in industry as a cost efficient alternative.

A METHOD OF DISTRIBUTED TEACHING SYSTEM REALIZATION BASED ON FUZZY MEASUREMENT OF USER'S FEATURES

The purpose of the paper is to apply the main ideas and methods of soft (fuzzy) measurements to the problem of network learning. Teaching system is considered to be really distributed. As secondary effect of its content (in some point of view it may be called primary) we suppose a method to increase an effectiveness of the WWW.

NEW UNIVERSAL SMART VISION SENSORS AND NEW INTUITIVE PROGRAMMING METHODS FOR VISUAL QUALITY MEASUREMENTS

The main purpose of the paper is to present a new kind of universal smart vision sensors and a new method for intuitive programming with icons on touch screens to overcome the existing well-known problems of subjective visual quality measurements by man. Practical examples will be demonstrated during the presentation.
