the new phase-ii n-glucoside metabolites of butobarbitone and pentobarbitone are identified and quantified in human urine after single doses of these drugs. the identification and quantification of these metabolites were carried out by mass spectroscopy technique (accurate mass measurement and high voltage scanning). it was found that the butobarbitone n-glucoside comprised 26% of the dose with...

This paper represents a three-phase precision measurement system for the electronic electricity meter based on a digital signal processor (DSP) in combination with a multichannel analog-to-digital converter. The measurement system capabilities include all the usual assessments of the energy, power, voltage and current, but functionality of this precision measurement system is extended into the ...

This paper introduces a distributed, self-organizing approach to load control based on voltage measurement. A local voltage measurement defines a Level of Service (LoS), which is balanced with the neighboring households in order to avoid extreme restrictions of energy use in a single household. The approach distinguishes four criticality classes for devices which suspend themselves at specific ...

− Recently we proposed an approach based on digital filtering for evaluating dynamic non-stationary contributions to the measurement uncertainty. A dynamic simulator instead of a digital filter bank is here utilized for deriving the dynamic measurement uncertainty of mixed capacitive voltage dividers. These are used for lightning impulse measurements, during a calibration measurement of a stand...

The amplitude and the transient time constant of the acoustoelectric voltage is measured as a function of temperature to determine the activation energy of deep levels in AI,Ga, -.As/GaAs grown by molecular-beam epitaxy. In comparison to other methods based on monitoring the capacitance transient, this method has several advantages. The technique is nondestructive, and because of the dependence...

Since all physical devices have a finite non-zero response time, the notion of delay between the input and output logic signals arises naturally once digital abstraction is done. This delay should be positive and non-zero, since a physical device takes a finite amount of time to respond to the input. Defining a strictly positive delay is not a problem in the abstract domain of logic signals, si...

 This paper analyzes accuracy of algorithms commonly adopted in instrument devoted to the detection and the characterization of voltage dips (also called sags). This analysis is particularly interesting because the results of dip measurements are utilized for calculation of severity levels and the site index assessment that are parameters adopted in determination of quality level of power supp...

Introduction: Well type ionization chamber is a measuring device which is used to determine the activity of brachytherapy sources. The chamber has a cylindrical volume in which a cylindrical tube is mounted in the middle of the chamber. For the measurements, the brachytherapy sources are transferred to the middle of the tube. Materials and Methods: For designing the well type chamber, the measu...
