Swing amplitude

A simple example of the parametric resonance is how one swings. One changes the center of one s body periodically, which enhances the swinging amplitude. Large swing corresponds to copious particle production in our problem. 

Antireflection coatings can be applied at the resist-substrate interface, in which case they are called bottom antireflection coatings (BARCs), or they can be applied at the surface of the resist, in which case they are called top antireflection coatings. The effect of top antireflection coatings on the swing amplitude S of resist materials is fairly well described by Brunner s formula ... 

Using Brunner s equations for swing amplitude, Eq. (9.1), it is possible to ratio the swing amplitudes for a given thickness of the BARC db to that of the substrate without BARC (i.e., d 0). In this way, the swing amplitude reduction 5rei relative to the substrate is obtained as the square root of the ratio of the reflectivities...

The thermostatic expansion valve is substantially an undamped proportional control and hunts continuously, although the amplitude of this swing can be limited by correct selection and installation, and if the valve always works within its design range of mass flow. Difficulties arise when compressors are run at reduced load and the refrigerant mass flow falls below the valve design range. It is helpful... 

For example, in a bipolar patient, reduction of the amplitude of mood swings may be the focus of acute therapy. During the maintenance phase, however, the most sensitive predictor of an impending relapse might be a decreased need for sleep. Careful attention to the onset of such a symptom might lead to early treatment, preventing a full-blown recurrence. 

For energy to be absorbed by this moving system, it must be in phase and in the form of an oscillation of the same frequency. This phenomenon is similar to that by which the amplitude of a swing is increased. 

We first draw a sketch depicting a pendulum and write down all the quantities which could be involved in this question [1]. It may be assumed that the period of oscillation of a pendulum depends on the length and mass of the pendulum, the gravitational acceleration and the amplitude of the swing ... 

There is little direct evidence of a biospheric uptake during the last few decades. However, indirect evidence exists. The amplitude of the seasonal swings in atmospheric CO2 concentration appears to have increased during the past 25 years (Machta, 1983b Keeling, 1983). These seasonal fluctuations are the result of differences in rates of photosynthesis and respiration during different seasons of the year, and it is inferred that increases in their amplitude in part reflect increases in the size of the biosphere in temperate and higher latitudes (Kohlmaier et al., 1983).

The difficulty with galvanostatic measurements with a fixed amplitude for the current perturbation is that such measurements can result in severe swings in potential, especially at low frequencies where the impedance is large. The amplitude of the potential variation associated with a perturbation of current is given by... 

Period of the pendulum) Suppose a pendulum governed by 0 -t- sin 0 = 0 is swinging with an amplitude a. Using some tricky manipulations, we are going to derive a formula for T(a), the period of the pendulum. 

Lithographic modeling has found widespread applications in the development of new lithographic processes and equipment. Such applications include the optimization of dye loadings in resists, the simulation of substrate reflectivity, the applicability and optimization of top and bottom antireflection coatings, and the simulation of the effect of bandwidth on swing curve amplitude.
