Instantaneous input electrical power measurements of HITU transducer

Instantaneous measurements of nonlocal variables

Relativistic causality imposes rigid restrictions on nondemolition (repeatable) measurements of nonlocal variables. We show that there are no causal restrictions on demolition (nonrepeatable) measurements: all Hermitian operators of multipartite quantum system can be measured instantaneously, provided unlimited supply of entanglement resources.

Electrical measurements

In this module we will learn the most important principles of making electrical measurements in general, i.e., to obtain voltages and currents using the appropriate instruments and connections, and to understand and minimize sources of error. Furthermore, we will discuss selected electrical measurement methods used to obtain chemical and physical information of liquids, solids, and interfaces. ...

Electrical Determination of Reciprocating Compressor Instantaneous Angular Speed

HVAC compressor units are major energy consumers in both residential and commercial buildings today. Faulty and energy wasting operation of these units often goes unnoticed due to the corrective action of feedback control. Power system monitoring is an exciting approach for creating inexpensive, highly capable methods to monitor compressor unit performance. In this paper we develop a method to ...

Microfluidic flow transducer based on the measurement of electrical admittance.

A new flow transducer for measuring the flow rate of a conducting fluid in a microchannel is reported. In this paper, the measure of flow of such fluid under laminar flow conditions based on the change of electrical admittance is established with the aid of a pair of electrodes parallel to the line of flow in a glass-PDMS microfluidic device. This flow sensor is simple in design and can be inte...
