Current sensor in pcb technology
(Institute of Electrical and Electronics Engineers (IEEE), 2005-06-01)
A novel dc/ac current sensor works on the fluxgate principle. The core in the form of a 7/10-mm ring made of electrodeposited permalloy is sandwiched in the middle of a printed circuit board (PCB), whereas the sensor ...
Markov processes, hurst exponents, and nonlinear diffusion equations: with application to finance
(Elsevier BV, 2006-09-01)
A multiwavelength view of the tev blazar markarian 421: correlated variability, flaring, and spectral evolution
(IOP Publishing, 2005-09-01)
We report results from an intensive multiwavelength monitoring campaign on the TeV blazar Mrk 421 over the period of 2003 - 2004. The source was observed simultaneously at TeV energies with the Whipple 10 m telescope and ...
Video measurements of near-surface bubble spectra
(Wiley-Blackwell, 2001-07-15)
Large bubbles > 300 mum radius have been observed at depths of between 10 cm and 1.2 m using a small video camera attached to a surface following float. In salt water, bubble spectra are presented for both limited fetch ...
Quantification of carbon dioxide, methane, nitrous oxide and chloroform emissions over ireland from atmospheric observations at mace head
(Informa UK Limited, 2002-01-01)
Flux estimates Of CO2, CH4, N2O and CHCl3 over Ireland are inferred frorn continuous atmospheric records of these species. We use radon-222 (Rn-222) as a reference compound to estimate unknown sources of other species. The ...
What the educators are saying

European greenhouse gas emissions estimated from continuous atmospheric measurements and radon 222 at mace head, ireland
(Wiley-Blackwell, 2000-01-01)
Flux estimates of CO2, CH4 N2O, and CFCs over western Europe have been inferred from continuous atmospheric records of these species at the atmospheric research 771 station of Mace Head, Ireland. We use radon ( Rn) which ...
Phasing segmented mirrors using defocused images at visible wavelengths
(Oxford University Press (OUP), 2006-02-21)
Plans for future optical telescopes of diameter more than 10 m are based on segmented mirrors, made up of hundreds or even thousands of segments. A challenge for these telescopes is the alignment in piston (cophasing) where ...
Distinctive activities of dna polymerases during human dna replication
(Wiley-Blackwell, 2006-07-01)
The contributions of human DNA polymerases (pols) alpha, delta and epsilon during S-phase progression were studied in order to elaborate how these enzymes co-ordinate their functions during nuclear DNA replication. Pol ...
Introduction: european integrated project on aerosol cloud climate and air quality interactions (eucaari) – integrating aerosol research from nano to global scales
(Copernicus GmbH, 2009-04-27)
The European Aerosol Cloud Climate and Air Quality Interactions project EUCAARI is an EU Research Framework 6 integrated project focusing on understanding the interactions of climate and air pollution. EUCAARI works in an ...
