Product Release Announcement Automotive Embedded Systems NXP Model-Based Design Toolbox for S32Z/E – version 1.3.0 The Automotive Processing, Model-Based Design Tools Team at NXP Semiconductors, is pleased to announce the release of the Model-Based Design Toolbox for S32Z/E version 1.3.0. Th...
TRUMPETS, bassoons and other long wind instruments are made with bends for compactness. They would function best if each bend behaved acoustically just like a definable segment of straight tube. The custom of the craft is to make each bend a semi-torus of the same bore diameter as the strai...
where \(Q\) is the discharge in m3/s, \(n\) the rotational speed of the turbine in rpm, \(E\) the specific hydraulic energy of the machine in J/kg, \(f\) the frequence of the electric system in Hz, \(p\) the number of pairs of poles of the trubine’s generator, \(g\...
The exponential distribution cumulative distribution function (CDF) can be derived through a specific formula: $$F(x)=\left\{\begin{array}{cc}1-{e}^{-\lambda x}& x\ge 0\\ 0,& \, {\text{otherwise}}\end{array}\right.$$ (2) ...

Furthermore, although the lower, upper, and target values of summer and winter wind speed need to be specified by the user, threshold values from empirical studies or existing standards are well-advised for deciding the parameters in the individual desirability functions. Show abstract Current ...
