OBJECTIVE To compare β-hydroxybutyrate (BHB) and glucose concentrations measured with a dual-purpose point-of-care (POC) meter designed for use in humans and a laboratory biochemical analyzer (LBA) to determine whether the POC meter would be reliable for on-farm measurement of blood glucose and BHB concentrations in sheep in various environmental conditions and nutritional states. ANIMALS 36 ...

Electromagnetic flow meters based on the principles of Faraday’s laws of induction have been used successfully in many industries. The conventional electromagnetic flow meter can measure the mean liquid velocity in axisymmetric single phase flows. However, in order to achieve velocity profile measurements in single phase flows with non-uniform velocity profiles, a novel Imaging Electromagnetic ...

According to the related technology about power meter, single-phase power meter based on Ethernet is designed and researched. Single-chip processor MC9S12NE64 is used as system’s CPU and in charge of the system control and information processing. Power measurement chip CS5460A is applied to calculate electrical parameters. EMAC and EPHY modules which are MC9S12NE64’s inter parts are adopted to ...

This new LCR Meter is especially designed for measurements of low-value components in integrated circuits and thinJilm hybrid circuits, as wellas of discrete components. /t uses a four-pair measurement technique to reduce errors caused by stray capacitance, residual inductance, and mutual inductance of the tesf /eads. T N THE MANUFACTURE of integrated circuits, I good process control is essenti...

Quantum measurement of amplitude fluctuation is performed by the injection of 2.5-dB amplitude-squeezed light produced by a quantum-well laser into the dark port of a beam splitter as the meter wave. It is shown that the measurements satisfy the criteria of quantum nondemolition measurement. The measured transfer coefficient and the quantum-state preparation ability are 1.07 and 0.8, respectively.

AIM To evaluate the properties of devices for measuring stray light and glare: the Nyktotest, Mesotest, "conventional" stray light meter and a new, computer implemented version of the stray light meter. METHODS 112 subjects, divided in three groups: (1) young subjects without any eye disease; (2) elderly subjects without any eye disease, and (3) subjects with (early) cataract in at least one ...

The Volume- Unit (VU) meter, used in speech research prior to the advent of computers and modern signal processing methods, is described in signal processing terms. There are no known software implementations of this meter, which meet the 1954 ASA standard and provide the instantaneous needle level. Important speech applications will be explored, such as making comparisons of speech levels to e...

We aimed to compare the measurements of sheep ruminal pH using a continuous telemetry system or a bench pH meter using sheep with different degrees of ruminal pH. Ruminal lactic acidosis was induced in nine adult crossbred Santa Ines sheep by the administration of 15 g of sucrose per kg/BW. Samples of rumen fluid were collected at the baseline, before the induction of acidosis (T 0) and at six,...

A new procedure of the linear position measurement which allows to obtain sensitivity better than the Standard Quantum Limit and close to the Energetic Quantum Limit is proposed and analyzed in details. Proposed method is based on the principles of stroboscopic quantum measurement and variation quantum measurement and allows to avoid main disadvantages of both these procedures. This method can ...
