The Taiwan Strait Crisis of 1954-55 and U.S.-R.O.C Relations

On September 3, 1954, Chinese artillery began shelling Quemoy (Jinmen), one of the Kuomintang-held offshore islands, setting off the first Taiwan Strait Crisis. This paper focuses on the crisis and analyzes the following three questions: (1) What was the policy the U.S. took towards the Republic of China (R.O.C), especially towards the offshore islands, to try to end the Taiwan Strait Crisis? (2) What were the intentions of the U.S. government in trying to end the Taiwan Strait Crisis? And (3) how should U.S. policy towards the R.O.C. which led to solving the Taiwan Strait Crisis be positioned in the history of Sino-American relations? Through analysis of these questions, this study concludes that the position the U.S. took to bring an end to crisis, one which prevented China from “liberating Taiwan” and the Kuomintang from “attacking the mainland,” brought about the existence of a de facto “two-China” situation.

The Cup Anemometer, a Fundamental Meteorological Instrument for the Wind Energy Industry. Research at the IDR/UPM Institute

The results of several research campaigns investigating cup anemometer performance carried out since 2008 at the IDR/UPM Institute are included in the present paper. Several analysis of large series of calibrations were done by studying the effect of the rotor’s geometry, climatic conditions during calibration, and anemometers’ ageing. More specific testing campaigns were done regarding the cup anemometer rotor aerodynamics, and the anemometer signals. The effect of the rotor’s geometry on the cup anemometer transfer function has been investigated experimentally and analytically. The analysis of the anemometer’s output signal as a way of monitoring the anemometer status is revealed as a promising procedure for detecting anomalies.
