Transmission Time

The transmission times can be used to determine the depth to the defects. As yet the use of this kind of testing in concrete is based on the rektilinear propagation of compression waves from the surface. No directional transducers for use on concrete are known to exist. 

A photoelectric technique has been devised whereby the position of the deton front in an expl can be measured. The light from the deton front is transmitted by a small-diameter optical fiber to the cathode of a photomultiplier tube where the light pulse is converted to an electrical pulse. Additional pulses may be generated by other fibers located elsewhere in the expl. All of the pulses may be recorded on an oscilloscope. The usefulness of the technique has been demonstrated by the measurement of the transmission times of detonators, the propagation velocities-of expl columns, the timing of expl systems, the vels...

Here the execution time (T) of the program is described as a function of the number of processors ( ), the problem size (N), the memory size (M), the latency and transmission time of remote memory references (fO,tl), and other relevant parameters. We understand already that T can be a nonlinear function of the problem size and sensitive to the algorithm [e.g., conventional self-consistent field (SCF),29 T(N) = 0 N ) + 0 N ) vs. pseudospectral SCF," T(N) = 0 N ) + 0(N3)], and similarly the dependence on P can be complex. As discussed earlier, one measure of the efficiency of parallel execution may then be derived as follows ...

In order to reduce off-line data space and transmission time, laboratory measurements and Monte Carlo simulations of the instrument are currently being used to develop data reconstruction algorithms based on three orthogonal ID projections of fiber output signals [Moser et al., 2004b],... 

Of the ionotropic receptors, there is a clear distinction between NMDA and non-NMDA receptors (Dingledine et al., 1999). The major differences are seen in the differences in transmission times non-NMDA receptors are thought to mediate fast synaptic neurotransmission, whilst NMDA receptors have a slow rise time, that the NMDA receptor requires a co-agonist glycine, is blocked in a voltage-dependent way by Mg " and modulated by Zn " and polyamines. Non-NMDA receptors exhibit none of the latter characteristics. This separation of NMDA receptors from the others is supported by the finding that there are clear structural differences between them (Barnard, 1997). 

Mraz et at (129) have described an automated technique for the thermo-acoustimetry of solids in which precise measurements of the transmission times of 5 and P waves across a sample of known dimensions can be made. 

Stellar X-rays have been observed to affect the transmission times of radio signals between distant stations by altering the depth of the ionospheric reflecting layer. It has also been suggested that variations in ionization of the atmosphere due to solar modulation may have observable effects on climatic conditions. 

An increasingly important issue is the relevance of directives in cases where the transmission time is over but no incorporation in national legislation has occurred. As a consequence of the latest decision of the Court of Justice, individuals can personally oblige member states to adopt a Directive if this is deemed to be beneficial. 

Errors in polygon chains produce unpredictable lines on the screen and can destroy the faithful reproduction of a drawing. To protect image transmission the software provides a controlled line protocol (KERMIT) slipped over the normal PAD protocol. Such a procedure is needed only when an unprotected line protocol is applied (for example the so-called TTY-Protocol supported by a DATEX-P PAD). Security of transmission costs about 50% more transmission time depending on the quality of the physical line. 

The measured quantities, service requests, or resource demands that are used to characterize the workload, are called workload parameters. Examples of workload parameters ate transaction types, instruction types, packet sizes, source destinations of a packet, tmd page-reference patterns. The workload parameters can be divided into workload intensity and service demands. Workload intensity is the load placed on the system, indicated by the number of units of work contending for system resources. Examples include arrival rate or interarrival times of component (e.g., transaction or request), number of clients and think times, and number of processors or threads in execution simultaneously (e.g., file reference behavior, which describes the percentage of accesses made to each file in the disk system) The service demand is the total amount of service time required by each basic component at each resource. Examples include CPU time of transaction at the database server, total transmission time of replies from the database server in LAN, and total I/O time at the Web server for requests of images and video clips used in a Web-based learning system. 

This means of sensory discrimination has practical value when applied to other types of problans. The location of a military target can be based on a combination of electronic anit-ters and receivers. Global positioning (GPS) can be ascertained similarly by comparing transmission times from various transmitting satellites to a receiver on Earth. Other triangulation schemes use the same principle.

Visual evoked potentials (VEPs) and brainstem auditoiy evoked potentials (BAEPs) measure speed of conduction in the nerves that ran from the eyes and ears, respectively, to the relevant locations in the brain. On stimulation, nerves send signals in the form of waves that can be detected, and the time it takes for an impulse to initiate an evoked potential is latency. The VEP is the first positive wave and usually occurs at 100 ms (PlOO latency) after the visual stimulus. That measure is very sensitive to demyelination of the optic nerve. BAEPs also have discrete waveforms. Wave I arises from the auditory nerve, and its latency reflects peripheral transmission time wave 111 is generated predominantly from the auditoiy pathway in the lower brainstem and wave V is generated from the upper brainstem. The use of interpeak latencies helps distinguish changes in peripheral auditory nerve latency from changes in brainstem transmission in the auditoiy pathway.
