HIGH PRECISION FLUXGATE CURRENT SENSOR [PDF]

, 2011
Nowadays the necessity to measure currents in the industrial worlds has been growth to the most important tools for proceedings controls. The classical approach of measuring current is by using a resistor and measuring the voltage drop across it.

Real-time information processing of environmental sensor network data using Bayesian Gaussian processes

, 2012
In this article, we consider the problem faced by a sensor network operator who must infer, in real time, the value of some environmental parameter that is being monitored at discrete points in space and time by a sensor network.

A Current Sensor Fault Tolerant Control Strategy for PMSM Drive Systems Based on C_ri Markers

Energies, 2021
The paper describes a vector-controlled fault tolerant control (FTC) structure for permanent magnet synchronous motor (PMSM) drives. As a control algorithm, the classical field oriented control was applied. For the proper operation of this drive, minimum

A semantic sensor web for environmental decision support applications [PDF]

, 2011
Sensing devices are increasingly being deployed to monitor the physical world around us. One class of application for which sensor data is pertinent is environmental decision support systems, e.g., flood emergency response.

CURRENT PROSPECTS FOR ASTROD INERTIAL SENSOR

International Journal of Modern Physics D, 2008
The Astrodynamical Space Test of Relativity using Optical Devices (ASTROD) is a multi-purpose relativity mission concept. ASTROD's scientific goals are the measurement of relativistic and solar system parameters to unprecedented precision, and the detection and observation of low-frequency gravitational waves to frequencies down to 5 × 10-6 Hz.

Energy managed reporting for wireless sensor networks

, 2008
In this paper, we propose a technique to extend the network lifetime of a wireless sensor network, whereby each sensor node decides its individual network involvement based on its own energy resources and the information contained in each packet.

Multi criteria adaptation mechanisms in homological sensor networks [PDF]

, 2008
One fundamental feature of sensor network is unpredictable and this brings us a challenge of how to design an adaptation mechanism to let a sensor network adjust itself based on current "context" and pre-defined network criteria which include coverage ...
