New approach to calibrate the mortar flow table

January 27, 2011
Author(s)
Chiara F. Ferraris, Haleh Azari
The flow table is a standardized test that is widely used to qualify a mortar to be tested for compressive strength and air content. It is also the only standard test to quantify a mortar workability property. Therefore, the calibration of this device is

Progress Toward Corrugated Feed Horn Arrays in Silicon

December 16, 2009
Author(s)
Joseph W. Britton, Ki W. Yoon, James A. Beall, Daniel T. Becker, Hsiao-Mei Cho, Gene C. Hilton, Michael D. Niemack, Kent D. Irwin
We are developing monolithic arrays of corrugated feed horns fabricated in silicon for dual-polarization single mode operation at 90, 145 and 220 GHz. The arrays consist of hundreds of platelet feed horns assembled from gold coated stacks of micromachined

Organic semiconductors are emerging as a viable alternative to amorphous silicon in a range of thin film transistor devices. , With the possibility to formulate these p-type materials as inks and subsequently print into patterned devices, organic based

NEW PRACTICAL METHOD FOR MEASUREMENT OF HIGH-POWER LEDS

October 1, 2008
Author(s)
Yuqin Zong, Yoshihiro Ohno
The measurement of high-power light emitting diodes (LEDs) has been difficult because they are highly sensitive to thermal operating conditions, and there has been a lack of common methods that can be used by both LED manufactures and users to acquire
