Peaks and mean

Decreased peak and mean urinary flow rate (less than 10 to 15 mL/s) on uroflowmetry decreased urinary flow rate is not specific for BPH it can also be due to other urological disorders (e.g., urethral stricture, meatal stenosis, or bladder hypotonicity)...

Muldple parameters can be calculated with CT perfusion imaging of the brain and include cerebral blood flow, cerebral blood volume, dme-to-peak, and mean dansit time (Wintermark etal., 2006). 

Wilt, T. et al. A recent meta-analysis of randomized controlled studies of using Serenoa to treat BPH was recently published in the Journal of the American Medical Association. The article concluded that patients and physicians rated saw palmetto as superior to the placebo and comparable to Proscar. Serenoa reduced nocturia by 25 percent compared to the placebo and ranked equally with Proscar at improving peak and mean urine flow rates and reducing residual urine. Side effects were comparable to the placebo and did not show the high erectile dysfunction rates associated with the use of Proscar. 

On closer inspection, relatively more accurate values for the tempemture peak and mean degree of cure have been found using the finite-element model, which has provided an overestimated value of the standard degree of cure. The finite-difference model seems to provide underestimated values for all parameters considered however, both analyses produce good agreement with experimental values.

Pump vibration measurements and analysis of the ampHtude—frequency spectmm have led to the deterrnination of possible equipment ailments. Examples of frequency relationships to particular pump vibration problems are available (62). Eor example, a one-time (lx) frequency corresponding to a mnning speed usually indicates the presence of rotor unbalance, a 2 x peak may mean a bent shaft, and a - O.dx may be a symptom of an oil whip at the sleeve bearing. 

Power factor correction circuits are intended to increase the conduction angle of the rectifiers and to make the ac input current waveform sinusoidal and in phase with the voltage waveform. The input waveforms can be seen in Figure C-2. This means that all the power drawn from the power line is real power and not reactive. The net result is that the peak and RMS current drawn from the line is much lower than that drawn by the capacitive input Alter circuit traditionally used. 

A summary of peak pressure and mean bulk temperatures in the various fixtures is shown in Table 6.3. Included in the characterization is the peak pressure along the axial few millimeter region along the axis of the samples (called focus) for which the radial focusing produces a high pressure region for a period of about 100 ns. 

Amplitude can be measured as the sum of all the forces causing vibrations within a piece of machinery (broadband), as discrete measurements for the individual forces (component), or for individual user-selected forces (narrowband). Broadband, component, and narrowband are discussed in Section 43.8 Measurement classifications. Also discussed in this section are the common curve elements peak-to-peak, zero-to-peak, and root-mean-square. 

All vibration amplitude curves, which can represent displacement, velocity, or acceleration, have common elements that can be used to describe the function. These common elements are peak-to-peak, zero-to-peak, and root-mean-square, each of which are illustrated in Figure 43.11. 

Note that for high reflectivities R, the transmission of the etalon varies from 1 to T /4. The higher the reflectivity R, the narrower the transmission peak and the higher the resolution of the etalon. Despite the finite reflectivities of the plates, interference means that the etalon is totally transparent at some combinations of wavelength and incident angle.
