Directional total emittance of three hard-coated glasses at 283 Κ
The directional total emittance at 283 Κ of three hard-coated glasses of medium to low emittance was measured over the angular range 10° to 84°. The measured values at 10° a r e 0.137 ± 0.003, 0.309 ± 0.006, 0.630 ± 0.008. The angular variadon correlates with these values: The lowest emittance glass is quasi metallic; the highest emittance glass is quasi dielectric; the intermediate glass is weakly metallic. Directional data are needed for the most accurate type of modelling of the thermal behaviour of glazing, and can also be used to refme the correction tables needed to obtain the corrected emittance from the normal emittance

Limitations of an amorphous‐metal magnetometer operated by modulating the magnetostrictive strain
Summarization: An analysis is presented of the characteristics of a magnetometer which uses an amorphous‐metal ribbon as its primary sensing element and which operates by modulating the magnetostrictive strain. Magnetic fields at the second harmonic of the modulation frequency are identified as capable of significantly degrading the magnetometer performance. A second‐harmonic field is measured and its contribution to the noise is estimated.Presented on

Directional total emittance of three hard-coated glasses at 283 K
Summarization: The directional total emittance at 283 K of three hard-coated glasses of medium to low emittance (Glasverbel's Thermoplus Comfort glass, whith a coating of doped tin oxide about 800 nm thick; Saint Gobain's EKO glass, with a coating of doped tin oxide about 180 nm thick; SIV's Solarsiv Blue 30/37, with a coating of titanium oxynitride about 30 nm thick) was measured over the angular range 10° to 84°. The measured values at 10° are 0.137±0.003, 0.309±0.006, 0.630±0.008. The angular variation correlates with these values: The lowest emittance glass is quasi metallic; the highest emittance glass is quasi dielectric; the intermediate glass is weakly metallic. Directional data are needed for the most accurate type of modelling of the thermal behaviour of glazing, and can also be used to refine the correction tables needed to obtain the corrected emittance from the normal emittance.Παρουσιάστηκε στο: Glass Science and Technolog
High-sensitivity low-frequency magnetometer using magnetostrictive primary sensing and piezoelectric signal recovery
Summarization: A simple and inexpensive magnetometer is presented which uses a piezomagnetic primary sensor together with a piezoelectric transducer to convert a magnetic field into an electrical signal. A linear operating range is achieved by employing a negative feedback configuration. The detection sensitivity is 1.5 x 10-4 A/m per Hz1/2at low frequencies.Presented on: Electronics Letter
