The intraseasonal oscillations(ISOs) of southern China spring rainfall(SCSR) are examined based on daily rain gauge rainfall data and NCEP/Department of Energy Reanalysis 2(NCEP-2) products for the period 1980–2008. The objective of this study is to reveal the structure and propagation of the ...
PROBLEM TO BE SOLVED: To provide a method capable of simplifying the structure of an adjust assembly and effectively and inexpensively adjusting the frequency of a spring balance. SOLUTION: In order to adjust the oscillation frequency of the spring balance, in a first step, the balance spring ...

The frequency of oscillation of an object suspended on a spring depends on the stiffness k of the spring (called the spring constant) and the mass m of the object. If the spring is compressed a distance a and then allowed to oscillate, its displacement is given by f(t)=acos √ ()tA...
The relative influences of board-tip rebound and fulcrum setting upon vertical board-tip oscillation during hurdle flight were investigated to gain insight into the mechanism by which highly skilled divers are able to make effective contact with the springboard. Data were collected on running dives ...
Then, the container 2 is supported on a body 5 whose oscillation is to be sensed through a coil spring 6 and a weight disk 7. The oscillation of the body 5 is buffered by the spring 6 and weight disk 7 to eliminate fine and slow oscillation, so that only oscillation having amplitude ...
of SIOD on the rainfalls in the next spring in China is greatest.In positive SIOD years,the rainfalls are subdued over the Yangtze River and its north in the next spring.While in negative SIOD years,the rainfalls increase over the Yangtze River and its north in the next spring.The ...
frequencies. Such systems often arise when a contrary force results from displacement from a force-neutral position and gets stronger in proportion to the amount of displacement, as in the force exerted by a spring that is stretched or compressed or by a vibrating string on a musical instrument...
Arctic ozone amount in winter to spring shows large year-to-year variation. This study investigates Arctic spring ozone in relation to the phase of quasi-biennial oscillation (QBO)/the 11-year solar cycle, using satellite observations, r... Y Yamashita,H Akiyoshi,M Takahashi - Multidisciplinary...
