Monitoring systems protect grain elevators against uncontrolled blasts and explosions. Many people die in fatal dust explosions every year. They cause material and building losses. In the paper I present the resultants of our experiment with monitoring system: temperature, humidity and other parameters. These systems are working with elastic temperature cables. Many parts of systems designees in intrinsic safety technique. The procedure of designing monitoring system has also been given.

Houses and instruments for the benefit of aged welfare have been developed as one of the solutions to this important problem of the next Century. To live in comfort and to save energy, the thermal environment in a model house for the aged has been monitored. It was made clear that floor heating and ceiling radiant cooling gave a comfortable environment to the aged due to uniform room temperature distribution and that air-conditioning cooling with a ceiling fan was energy efficient.

Implementation of mapping refered to “localized” quantities from Remote Sensing (i.e.) is based on known information processing, on a set of bi-dimensional Space coinciding normally with the same mapping. An usual representation of interested objects is “ contouring”, that allows to illustrate the curve, place of points that have the same value. This representation is obtained by using known value interpolation of quantities of interest. The widespread approaches to generate interpolating surfaces, using personal computer, through Intrinsic Random Function in Remote Sensing are considered in...

The process of acquiring small format aerial digital images for assessing land cover classification of Landsat Thematic Mapper (TM) satellite images is discussed. Images positional accuracy and suitability for assessing land cover classification is tested. Using an economic configuration of onboard navigation sensors, a positional accuracy of 15 m in the images center points locations can be achieved. In addition, dithered 3 band color infrared images can be used for assessing land cover classification of TM satellite images.

Engineering for disassembly of waste products is becoming increasingly complex. Furthermore, customer expectations are growing, competition is becoming harder, legal requirements are stricter and the quality of technical products is continuously improving. FMEA is a formalised, analytical method for the systematic, consistent collation and prevention of potential sources of errors and their results, not only in Design, but also in Planning and Production and in the future especially for Disassembly in the field of Recycling. The aim of the method is timely recognition and information on...

At present, no standardized procedures exist for regulating the process of calculating the certainty of measurement results. Taking geometric measurement activities in the production engineering environment as an example, the presentation indicates methods of establishing mathematical parameters for statistical assessment purposes as a means of ensuring that results can be reliably compared. When it comes to evaluating the ability of measuring instruments to permit quality standards to be reliably assessed, measuring uncertainty is an important factor. Moreover, even describing the...

In the contribution are stated new tendencies used at quality control branch today. These tendencies support production effectiveness in most general form. Upon correct and consequential application they may also help to find out critical places of the processes. Nowadays quality can not be understood just like specialisation, respectively like added value, but must be embraced like indivisible part of all processes. In contribution is deeply described problems of management of quality cycles, PDCA cycles and shortly is shown principle of Quality Journal methodology. Mentioned tendencies are...

When facilities of images are used to control geometric quality of objets, these have to own match marks, which are reconstructed in 3D, if couples of 2D points of such marks on images are matched by a human or artificial recognition process. Particular applications may avoid match marking and human recognition, but it is necessary to locate objets with particular orientation in precise known places. On the other hand, precise location of objets into virtual reference systems, when those were located freely, is one characteristic of interest in many industrial applications. Some applications...

Measurement is a key decision tool for a sustainable growth. In order to cope with this goal, total quality of measurement should be pursued at all operative levels, ranging from company or laboratory, through the national and macro-regional levels, up to the international dimension. In the paper, a framework for achieving required measurement quality is proposed and discussed. For each operation level, involved subjects are identified, concerned actions are considered and integration and harmonisation is addressed.
