Single-shot methods

In Fig 4, Method A is for single shots Method B is for multiple shots or rotation firing in wet holes and Method C for multiple shots or rotation firing in dry holes or for wet holes providing plastic covered fuse is used... 

We close this section with a consideration of when a single-shot method as we have described is useful and when... 

Walk (of hole) The tendency of a wellbore to deviate in the horizontal plane. Wellbore survey calculation methods Refers to the mathematical methods and assumptions used in reconstructing the path of the wellbore and in generating the space curve path of the wellbore from inclination and direction angle measurements taken along the wellbore. These measurements are obtained from gyroscopic or magnetic instruments of either the single-shot or multishot type. 

An analytical method has been developed that allows easy standardless semiquantitative measurements of elemental composition from single shot analysis by LA-ICP-ToFMS to identify alloys of different elemental composition.27 28 This method directly compares adjusted ion signals of... 

To overcome immobilization of biological substances and to establish diffusion limitation a number of methods have been tried. For example in the mediated disposable glucose sensor screen printing of free enzymes and mediator have been used. Due to the solubility of both substances only single shot apphcations are possible. For long term applications more sophisticated methods are necessary.

The nanosecond-picosecond two-color two-laser flash photolysis method is also useful to study the excited state of radicals, that is, the D, state. We applied nanosecond-picosecond two-color two-laser flash photolysis to detect the absorption and fluorescence spectra of the ketyl radical of benzophenone and its derivatives (BPH and BPDH ) in the excited state in the UV-visible region [111], since BPH and BPDH are well investigated radicals in various fields. Since BPH and BPDH are generated from irreversible ways, such as photoionization, we employed a streak camera to realize the single-shot detection of these intermediates. 

Population inversion is often achieved by a multi-level atomic or molecular system in which the excitation process, called pumping, is accomplished by electrical means, by optical methods, or by chemical reactions. In some cases, the population inversion can be sustained to produce a continuous wave (CW) output beam that is continuous with respect to time. In other cases, the lasing action is self terminating, so that the laser is operated in a pulsed mode to produce a repetitive pulse train or a single-shot action. ... 

Shaped and composite pulses are devoid of free precession periods between periods of rf excitation. Pulse sequences combine both free precession and rf pulses. Clearly, given the manifold of shaped and composite pulses, there is an infinite number of pulse sequences which can be constructed from them. A variety of such sequences is used for volume localization. This topic is discussed in Section 10.2. Here two methods relevant to the acquisition of NMR images are reviewed. These are the DANTE technique for single-shot localization, and the Hadamard technique as an example of multi-shot localization. 

A streak camera which has 12 ps shot-to-shot jitter has been developed. With this degree of precision, a simple method of signal averaging of picosecond fluorescence events may be employed direct summation. This results in a substantial increase in the signal-to-noise ratio of time-resolved fluorescence measurements over single-shot records.
