Instrumental Uncertainty of Conductance Transducers for Maritime Reduced-Scale Models

This paper aims to determine the instrumental measurement uncertainty of conductance transducers for maritime reduced-scale models developed in hydraulic experimental facilities. These transducers are used for the measurements of wave levels and their variations under a dynamic regime (being the measurement principle and method briefly described in the paper). Several metrological characterization methods are also presented, aiming to identify and quantify measurement uncertainty components, namely electrical stability, linearity, reversibility, repeatability, and thermal influence. The obtained results were applied in the evaluation of the transducer instrumental measurement uncertainty.

General principles of ground of efficiency of informatively-measuring technologies in the process of exploitation of objects of the real estate

Aim of this work – to set forth general principles of ground of efficiency of informatively-measuring technologies in the process of exploitation of objects of the real estate. Methodology. The method of substantiating the effectiveness of the restoration of the technical condition of real estate in the process of their operation is based on the use of information and measurement technologies to establish the technical condition of the object, which is a combination of information retrieval methods, instrumental measurement, analysis and processing of such information, technological and technical solutions to ensure the operational suitability of the facility in conditions of uncertainty. The method involves the formation of a repair strategy using information and measurement technologies based on the development of the life cycle of repairs and algorithms for selecting options for instrumental monitoring systems, choosing the procedure for studying the duration of measurement work, justification of labor and information technology costs and comparative assessment of total costs of real estate object. Results. It is established that measuring works are an integral part of the process of operation and repair work in its composition, which are carried out according to a single schedule of operation of the building and are part of repair work, and the frequency and volume of measuring, including geodetic work correlate with. To plan the volume of measuring work, their duration and labor costs are determined on the basis of existing time norms, and in their absence – by methods of technical rationing. Substantiation of the effectiveness of information and measurement technologies in the operation of real estate is performed by comparative assessment of total costs during the operational stage of its life cycle, taking into account the costs of implementing information and measurement technologies, that is the set of processes for obtaining information by instrumental measurement and processing ‘effective conclusion on the technical condition of the property. The scientific novelty of the obtained results is in the development of general principles for substantiating the effectiveness of information and measurement technologies in the operation of real estate. The practical significance lies in the improvement of standard solutions for the choice of composition and content of information and measurement technologies, taking into account their impact on the duration and labor costs of all types of repairs and reconstruction.

Optimising the Validity of Shoulder Range of Motion Evaluation: A Comparative Study

During the assessment process diachronically conceived in the initial, dynamic, and final stages, data recording is often performed by instrumental measurement using the goniometer. In Romania, the logistics equipment - hardware and software - has a very low or even absent incidence in the conceptual and applicative design of kinetic rehabilitation programmes. Some disadvantages of universal goniometry are revealed by relatively accurate measurements, given that the testing instrument may provide erroneous data when the specific rules are not followed. Moreover, the tester’s interpretation of angular values may vary; therefore, in order to objectify and validate the specific assessment and evaluation, we propose a precise angular motion measurement device called Kinesimeter, assisted by specific Labview software designed at the Human Movement Science Discipline of “George Emil Palade” University of Medicine, Pharmacy, Science and Technology of Târgu Mureș. Our purpose was to compare the results and interpret the differences arising from the use of two specific assessment methods for the shoulder range of motion. Thus, the values recorded by two physiotherapists using the manual goniometer were compared with the values recorded with the Kinesimeter. In order to validate the results, we calculated statistical parameters such as correlation and significance. We strongly believe that the proposed hardware and software device for measuring, controlling, and analysing shoulder movements can become a modern performing tool needed by each rehabilitation institution, having a dual role - investigative and monitoring of a rehabilitation programme - both extremely important, additional to current measurements with the goniometer.
