The choice of the signal processing method may improve characteristics of the measuring device. We consider a measurement error of the signal processing regression methods of a quasiharmonic signal generated in a frequency selective device. The results applied to analyze the difference between the simple period meter processing and regression algorithms using measurement cycle signal data in pr...

This paper presents a detailed model of common rail diesel injector and its validation using injection rate measurement. A new method is described for nozzle flowrate determination simulation measurement tools. The contains fluid dynamic, mechanic electro-magnetic systems, describing all-important internal processes also includes the meter model. Injection measurements were made Bosch method, b...

In this paper, a novel method is proposed for multi-information acquisition from the electromagnetic flow meter, using magnetic excitation to measure the fluid velocity and electrochemistry impedance spectroscopy (EIS) for both the fluid quality and the contamination level of the transducer. The impedance spectra of the transducer are measured with an additional electrical stimulus in series wi...

1.1 This test method covers the measurement of steady state thermal transmission through flat slab specimens using a heat flow meter apparatus. 1.2 The heat flow meter apparatus is used widely because it is relatively simple in concept, rapid, and applicable to a wide range of test specimens. The precision and bias of the heat flow meter apparatus can be excellent provided calibration is carrie...

We outline a framework for describing photoactivated biological reactions as generalized quantum measurements of external fields, for which the biological system takes on the role of a quantum meter. By using general arguments regarding the Hamiltonian that describes the measurement interaction, we identify the cases where it is essential for a complex chemical or biological system to exhibit n...

Various approaches of defining and determining work performed on a quantum system are compared. Any operational definition of work, however, must allow for two facts: first, that work characterizes a process rather than an instantaneous state of a system and, second, that quantum systems are sensitive to the interactions with a measurement apparatus. We compare different measurement scenarios o...

The noise is one of the negative elements which affects the human health. This article presents the measurement of emitted noise by road vehicle and its parts during the operation. Measurement was done in the interior of common passenger cars with a digital sound meter. The results compare the noise value in different cars with different body shape, which influences the driver’s health. Transpo...

The paper shows that innovative technologies for noninvasive monitoring of the cerebral blood flow autoregulation, cerebral blood flow pulse and slow waves also for the registration of the reactions to the neurodiagnostic tests can be developed on the basis of the precise measurement of brain parenchyma acoustic characteristics. The innovative technological equipment for such measurement has be...

This article critically examines Saul Kripke’s (1972) argument for the separability of necessary truths from truths known a priori, focusing on his criticism of the standard meter case presented by Wittgenstein (1968). It attempts to show that Kripke’s argument is unworkable on any of several readings. Wittgenstein’s own broadly conventionalist account of necessary truth is then considered in t...

BACKGROUND Most processes for fabricating biosensors applied to screen-printed carbon electrodes (SPCEs) are complex. This study presents a novel one-step process for manufacturing electrodes for injection-molding biosensors. METHODS During the sensor-fabrication process, barrel-plated gold electrodes were inserted into an injection-molded base. The electrode directly touched the electrical c...
