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.
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.
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.
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...
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.
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.
The aim of this work is to develop a lowoverhead, low-cost built-in test for Micro Electro Mechanical Systems (MEMS). The proposed method relies on processing the Impulse Response (IR) through trained neural networks, in order to predict a set of MEMS performances, which are otherwise very expensive to measure using the conventional test approach. The use of neural networks allows us to employ a low-dimensional IR signature, which results in a compact built-in test. A MEMS structure combining electro-thermal excitation and piezoresistive sensing was chosen as our case study. A behavioral...
The article concerns the implementation of shape designed complementary signals in BISTs used in mixed-signal embedded systems for testing of their analog sections. The essence of the proposed method is stimulation of the tested circuit with a complementary signal of a designed particular shape, whose parameters are matched to the nominal position of circuit transfer function poles. The paper presents results of simulation research and practical verification of the method in a microsystem based on an ADuC814 microcontroller.
A new class of multi-port methods based on extension of input-output two-port methods of soft fault diagnosis of passive elements in analog circuits is presented. It uses accessible internal nodes of the tested analog circuit for additional measurements of circuit time responses. Thanks to this, the fault resolution increases, that is we obtain better fault localization coverage.
A new method of diagnosis of single faults of passive elements in analog electronic circuits, based on the node-voltage relation approach, is presented. This method consists of two parts: creation of a fault dictionary describing the nominal state of the tested circuit and containing indirect parameters representing respective faults, and a new fault detection and localization algorithm.
