This paper treats an induction machine as a wind power generator, and voltage deviation due to wind velocity change is simulated by a dynamic stability calculation program. The ac bus voltage connected to the wind generator highly depends on the wind velocity variation. Then author actually measured the wind velocity which is used for the simulation. This paper shows 1 second sampling data of t...

conclusions large-scale studies on the healthy black african population could assess the relationship between diastolic dyssynchrony and changes in myocardial performance related to racial differences. results the frequency of some dyssynchrony markers was similar to that of other studies. the difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity w...

BACKGROUND The immediate postnatal period is the period of the fastest growth in the entire life span and a critical period for lung development. Therefore, it is interesting to examine the association between growth during this period and childhood respiratory disorders. METHODS We examined the association of peak weight and height velocity to age 36 months with maternal report of current as...

This paper discusses the large-deviation principle of discriminant statistics for Gaussian locally stationary processes. First, large-deviation theorems for quadratic forms and the log-likelihood ratio for a Gaussian locally stationary process with a mean function are proved. Their asymptotics are described by the large deviation rate functions. Second, we consider the situations where processe...

Monin-Obukhov theory predicts the well-known log-linear form of the vertical wind speed profile. A turbulence intensity profile can be estimated from this by assuming that the standard deviation of the wind speed is proportional to the friction velocity. Two parameters, namely the aerodynamic surface roughness length and the MoninObukhov length, are than needed to predict the vertical wind spee...

Using literature data on solubilities, equations have been constructed for the correlation of solubilities of liquids and solids in dry octanol, as log Soct (M). The best equation statistically uses Abraham descriptors together with the compound melting point. For 282 compounds the equation standard deviation is no more than 0.47 log units. If the melting point term is omitted the standard devi...

Code Division Multiple Access Communications Sang Wu Kim1 and Andrea Goldsmith Dept. of Electrical Engineering California Institute of Technology Pasadena, CA 91125 Abstract We analyze the performance of the truncated power control scheme in code division multiple access communication systems, which compensates for fading above a certain cuto fade depth. We investigate the power gain as well as...

The growth of 26 short normal prepubertal children (mean age 8.4, height velocity standard deviation score for chronological age between +0.4 and -0.8) was studied for two years. Sixteen children were treated with somatrem (methionyl growth hormone) during the second year, and the remaining 10 children served as controls. During one year of treatment the height velocity standard deviation score...
