Accelerating power

Fig. 4. Throughput versus dose for different accelerator powers.

For most electron-curable adhesives, a dose of 100 kGy is required to cure. Fig. 4 shows the speed of curing various widths of material as a function of accelerator power. A reasonably controllable speed for moving parts through an accelerator would be approximately 10 m per minute. Based on this criterion, the lower wattage limit for an accelerator curing an adhesive strip 5 cm wide would be 5 kW. For curing very large parts a 50 kW accelerator would be more suitable. 

The EPS unit is rated at 10 kw. accelerator power and is capable of treating some 340 sq. ft./min. to 1 Mrad (31.6 sq. meters/min.). This is empirical data, and allowance has been made for efficiency considerations.

The inertia and damping characteristics can be represented by an accelerating power term and a frictional or damping power term in a simplified second-order differential equation for each generator. Also in the eqnation is a term for the electrical power generated. The right-hand side of the equation represents the mechanical power that is applied to the shaft of the generator. 

Where Pa = accelerating power for the polar moment of inertia. 

Summary The recurring theme in the above examples is that a minor delocalizing interaction can be inactive at the most stable ground state geometry defined by an alternative stronger interaction that moves the system perpendicularly to the desired reaction coordinate. The stereoelectronic readjustment requires a conformational change and comes with a thermodynamic cost. When such readjustment is unnecessary, the role of stereoelectronic effects is revealed clearly and their accelerating power is ntihzed fully.

Kjeang et al. wrote in 2009 With the exception of a lunited number of stationary units, large-scale fuel cell heat and power plants have not yet gone beyond the field of trial stage (small-scale commercialization). Small fuel cells for portable electronic equipment are considered rather close to market for a number of reasons. It is unlikely that technical development of batteries will keep pace with the accelerating power demand for portable electronic devices. The market for portable electronics has an inherently high cost tolerance. ...

However, we saw above that host flexibility is the key to e co-selectivity in the Diels-Alder reaction of Fig 6. Indeed the linear porphyrin dimer in Fig. 7 retains all the stereoselectivity and much of the accelerating power of its cyclic analogue even though the porphyrin units can sweep out great circles in conformational space by rotation...

The most common way to present the micro-seismic noise at a station is to compute acceleration power density spectra and to display the probability of noise levels over a longer time period on probability density plots (McNamara and Buland 2004 McNamara and Boaz 2005). An example is shown in Fig. 7. This type of plot allows the identification of the different noise sources that act at different frequencies. However, one needs to be aware that the real ground noise is only resolved in a specific frequency range depending on the equipment. 

According to Fig. 2, variations in noise acceleration power are typically within about... 

In Fig. 2, however, a comparison has been made of the respective numerical values for physically inconunensurable quantities such as acceleration power density with velocity and displacement power density. Therefore, Eqs. 2 and 3 and the following two text lines do not imply that the decibel units on both sides of the equal sign mean the same. They only look the same because the incommensurable reference levels were omitted. For this reason, three decibel scales for acceleration power, velocity power, and displacement... 

A common technique for measuring noise is frequency domain analysis, such as plotting the acceleration power spectral density (PSD) of the seismic data over some time period. While tmies are readily distinguishable from broadband noise, nonstationary events such as pops have a broadband spectral characteristic (typically proportional to j) that can nuslead the troubleshooter. However, small pops may not be readily identified by examining the time-domain time-series data as they may have amplitudes too small to be distinguished from the background seismic activity.
