Wind-Electric Power Potential Assessment for Three Locations in East Java-Indonesia

This paper reports our effort to asses wind energy potentials for three locations in East Java. We used wind speed data over a period of almost 3 years, i.e. in period of June 2006 – August 2008. Data were taken from direct measurement in locations in East Java Province, i.e. Sampang (Madura), Juanda (Surabaya), and Sawahan (Nganjuk). The short-term of wind speed mean in monthly signifies to wi...

Twenty-watt average output power, picosecond thin-rod Yb:YAG regenerative chirped pulse amplifier with 200 μJ pulse energy

A high-average power, laser-diode-pumped, picosecond-pulse regenerative chirped pulse amplifier was developed by using the thin-rod Yb:YAG laser architecture. An average output power of 20 W was achieved at a repetition rate of 100 kHz with an output pulse width of 2 ps. 2008 Optical Society of America OCIS codes: (140.3280) Lasers, amplifiers, (140.3615) Lasers, ytterbium, (140.3480) Lasers, ...

The new METAS Watt Balance, Mark II

In the context of the future new definition of the mass unit, kg, a promising route to link the mass unit to a fundamental constant, the Planck constant h, is represented by the watt balance experiment. Since a number of years, the Federal Institute of Metrology is active in this field and published a first result with its Mark I experiment in 2011. To reach the target uncertainty of 2 parts in...
