Intelligent information processing in a digital library using semantic web
(2009)
With the explosive growth of information, it is becoming increasingly difficult to retrieve the relevant documents with current search engine only. The information is treated as an ordinary database that manages the ...

Flowmeter random error estimation by an analytical variance estimation method: a simple test bed
(Elsevier, 2004)
This paper uses an experimental method to estimate the variance of flowmeter errors (random errors or Type A errors), focusing on problems of detecting defects existing in sensors even with verysmall magnitudes. An ...

A method for foF2 short-term prediction
(Elsevier, 2000)
A method for foF2 short-term prediction with 1–24 hour lead times is proposed. It is based on ΔfoF2 (deviation of hourly foF2 from running median) regression with the previous ΔfoF2 observations and hourly spline-interpolated ...

Effects of geomagnetic storms on the ionospheric regions over the Southwest of Europe. An approach to the influence of the G condition on ionospheric values
(Akadémiai Kiadó, 2002)
The effects of three geomagnetic storms on the ionospheric F region and the influence of the G condition on TEC estimates have been analysed by using ionospheric data from INTA El Arenosillo Atmospheric Sounding Station ...

A 800 kW wind-diesel test bench based on the MADE AE-52 variable speed wind turbine
(IEEE Xplore, 2003)
A field work have been made about the practical installation of a wind-diesel autonomous power system. A remarkable innovation on the control of the latter wind-diesel system is the ability of taking advantage of the kinetic ...

Experimental study on the transmission of measurements by tolerance in SCADA systems
(IEEE Computer Society, 2004)
The study of the existing relationship between a measurement error and the time elapsed since that measurement was taken in the field, a period of time which we will call the datum age, will allow us to learn about its ...

A new QoS routing algorithm based on self-organizing maps for wireless sensor networks
(Springer, 2007)
For the past ten years, many authors have focused their investigations in wireless sensor networks. Different researching issues have been extensively developed: power consumption, MAC protocols, self-organizing network ...

The 11.08.1999 solar eclipse and the ionosphere: a search for the distant bow-wave
(Elsevier, 2001)
The advantage of studying eclipse disturbances is the perfect predictability of their 4D source geometry, which allows for preparation of adapted systems and schedules. The total solar eclipse period of August 11, 1999 ...

Power Systems Monitoring and Control using Telecom Network Management Standards
(IEEE Computer Society, 2005)
Historically, different solutions have been developed for power systems control and telecommunications network management environments. The former was characterized by proprietary solutions, while the latter has been ...
