Single-sided mode

ASTM C1044, 2003. Standard practice for using a guarded hot plate apparatus or thin heater apparatus in the single sided mode. 

The interferogram is measured on both sides. Data are acquired during the forward movement of the mirror. This mode yields an improvement in the signal-to-noise ratio as compared to the Single Sided mode. The resolution in time however amounts to half the value achieved in Single Sided mode. 

Improvements in the single side-band performance of a mixer-based receiver can be made by filtering the unwanted side band before it is down-converted in the mixer. Such a scheme, which is described in detail by Goldsmith (1982) is based on interferrometric techniques. We will not discuss single side-band filtering any further, except to note that it is a particularly apposite demonstration of the use of optical techniques to process the radiation in the spectrometer. We will discuss the use of interferometric techniques in Section IX as a means to realize a reflection mode spectrometer. These few examples indicate the flexibility of application of optical techniques to problems of instrument design in the FIR. 

The right-hand side of Eq. 23 vanishes unless AG/ boj) is an integer. This inconvenience arises from our initial assumption that the reaction coordinate Q constitutes a single normal mode with the energy quantum hm. In reality, Q should be composed of various normal modes of phonons with various energy quanta. 

Diode lasers have interesting spectroscopic properties. They produce radiation of single spatial and longitudinal modes at a maximum injection current and side modes at low diode current, down to <1% of the radiation power at maximum... 

Schematic diagram of the HFRLM process in single-pass mode is shown in Figure 32.2. Hydrophobic hollow fibers are used, whose pores are filled with the organic phase. The stirred mixture of organic phase and feed phase (or stripping phase) at a high W/O volume ratio is pumped through the lumen side of the module. The organic phase droplets are uniformly dispersed in the mixture by stirring. The stripping...

In addition to single ring microresonator structures, coupled ring microresonator structures have been fabricated [114]. These amplify the tuning sensitivity factor by the Vernier effect and amplification factors of 40 have been demonstrated. Coupled ring microresonator structures also lead to enhanced side mode suppression. Recently, a novel new architecture for multiple ring microresonators coupled to linear waveguides has been demonstrated [115]. 

NOTE The estimated rates of failure of a subsystem can be determined by a quantified failure-mode analysis of the design using component or subsystem failure data from a recognized industry source or from experience of the previous use of the subsystem in the same environment as for the intended application, and in which the experience is sufficient to demonstrate the claimed mean time to failure on a statistical basis to a single-sided lower confidence limit of at least 70 %. 

While the electrospinning of polymer blends is often desirable in order to achieve the proper combination of properties, it may not be possible by using a single needle configuration if the polymers of interest are not soluble in a common solvent. Thus, it may be necessary to use a side-by-side mode, hi this configuration two separate polymer solutions flow through two diffa ent capillaries, which are set side-by-side. 

In the standard description of the dielectric properties of the chiral tilted smectics worked out by Carlssonet al. [152], four independent modes are predicted. In the smectic C the collective excitations are the soft mode and the Goldstone mode. In the SmA phase the only collective relaxation is the soft mode. Two high frequency modes are connected to noncollective fluctuations of the polarization predicted by the theory. These two modes become a single noncollective mode in the smectic A phase. There is no consensus [153] as yet as to whether these polarization modes really exist. Investigations of the temperature dependence of the relaxation frequency for the rotation around the long axis show that it is a single Cole-Cole relaxation on both sides of the phase transition between smectic A and smectic C [154]. The distribution parameter a of the Cole-Cole function is temperature-dependent and increases linearly (a=a-pT+bj) with temperature. The proportionality constant uj increases abruptly at the smectic A to SmC transition. This fact points to the complexity of the relaxations in the smectic C phase. 

Figure 3.9. In the single detector mode, RF carrier is placed outside the spectral region at one end of the spectrum. Setting a large spectral width results in the folding back of the noise from the other side of the RF carrier, leading to a reduction in signal-to-noise ratio.
