Events correlated

When Kevlar fibers were stressed in tension, a stranded form of fracture was observed, which resulted in multiple EE/PIE peaks spread over several hundred microseconds. The total emission from the entire fracture event correlated with the extent of "damage" to the fiber in fracture. Examination of the shape and intensity of the EE/PIE bursts could provide indications of the mechanism of failure, by differentiating between fibril formation and pull-out. 

EBE Early biological effect represents an event correlated with, and possibly predictive of, a health effect. 

In this paper, we present a distributed application for acquiring events. The application is fully distributed and has the ability to concentrate information from multiple heterogeneous formats into a single database for event correlation and visualization. An event in the context of this paper... 

Unless the Host Identity Protocol2 provides a solution to these issues, we anticipate that they will remain and that event correlation will suffer from the fuzziness of host identification. 

The operative concept for genetic events correlating LOH and cancer is that the physical deletion of genetic information in regions showing LOH causes the... 

The assay procedure may not measure metabolites of a drug that are pharmacologically active, e.g. some benzodiazepines, or may measure metabolites that are pharmacologically inactive in either event correlation between plasma concentration and effect is weakened. 

In attempts to lower the amprenavir capsule burden, low-dose ritonavir has been used as a pharmacokinetic booster. When ritonavir was added to amprenavir, the amprenavir AUC increased 3-4 times (13), which should allow the total daily capsule burden to be reduced. Adverse effects included diarrhea, nausea, paresthesia, rash, increased cholesterol, and increased triglycerides. The frequency of adverse events correlated with the dose of ritonavir. 

Many geological events correlate with a major change at the Archean-Proterozoic Boundary. The widespread oc-... 

From the literature reviewed in the present chapter, it appears that lycopene is an important compound in coimection with the onset and the progression of cancer. Important epidemiological studies have traced the path that has been followed by the first clinical interventions and by the animal studies. Cellular mechanisms have appeared as well to show that the human and animal results are based on specific molecular events correlated with regulation of the cell cycle. An additional step in understanding the... 

The events correlated with the I-N transition on cooling occur as a two-stage process [36, 39]. 

In the second half of the 1990s, mainly Park et al. from Korea published several papers on BF-reinforced composites. They tested polycarbonate (PC)" and epoxy resin (EP) based polymer composites with the methods of single fiber fragmentation and acoustic emission. It was found that in the case of PC matrix composite (when aminosilane was used as a treating agent), the number of acoustic events correlated well with the value of the interfacial shear strength determined from the fragmentation tests. 

We can now correlate all events below or above the datum plane by comparing the log response. In many instances correlations are ambiguous. Where two or more correlation... 

These events will need to be marked on the correlation panel. In case of faulfs the thickness of the missing section or cut out should be quantified. 

However, it is possible that friction events from rubbing between fractured surfaces can be generated at low load levels also during the loading part of the cycle. This is depicted in the two correlation plots of Figure 5. In the plot at the bottom, these events are marked with a rectangle. It was decided that in addition to the previous filter, another filter based in load level should be added. Acoustic emission events were thus accepted only if they occurred at a load higher than 85% of the maximum load level of the test. 

Digital Signal Processor board fPSP) it is hosted into the PC and processes in real time the binary sequences stored into the acquisition board FIFO memories. The board processes arrival times and extracts the correlated AT generated by AE events. The PC picks up the data stored into the DSP memories and calculates the position of the AE sources. 

The results of over 1 year of continuous, on-line acoustic emission (AE) structural surveillance of high temperature / high pressure steam headers, gained on 2 M-scale 600MW supercritical multifuel ENEL power units in normal operation, are presented in the paper. The influence of background noise, the correlation between plant operating conditions (steady load, load variations, startup / shutdown transients) and AE activity and the diagnostic evaluation of recorded AE events are also discussed. 

The above approximation, however, is valid only for dilute solutions and with assemblies of molecules of similar structure. In the event that concentration is high where intemiolecular interactions are very strong, or the system contains a less defined morphology, a different data analysis approach must be taken. One such approach was derived by Debye et al [21]. They have shown tliat for a random two-phase system with sharp boundaries, the correlation fiinction may carry an exponential fomi. 

Correlated events are related in time and this time relation can be measured either with respect to an external clock or to the events themselves. Random or uncorrelated events bear no fixed time relation to each other but, on the other... 

In this section we have examined the issue of time with respect to the processing and recording of signals and also with regard to statistical uncertainty. These are considerations that are the basis for the optimization of more complex experunents where the time correlation between sets of events or among several different events are sought. 

Coincidence experiments explicitly require knowledge of the time correlation between two events. Consider the example of electron impact ionization of an atom, figure Bl.10.7. A single incident electron strikes a target atom or molecule and ejects an electron from it. The incident electron is deflected by the collision and is identified as the scattered electron. Since the scattered and ejected electrons arise from the same event, there is a time correlation... 

Referring to figure BLIP. 7 consider electrons from the event under study as well as from other events all arriving at the two detectors. The electrons from the event under study are correlated in time and result in a peak in the time spectrum centred approximately at the delay time. There is also a background level due to events that bear no fixed time relation to each other. If the average rate of tlie background events in each detector is R and i 2> then the rate that two such events will be recorded within time Ax is given by i g, where... 

Figure Bl.10.12. Schematic diagram of a two-dimensional histogram resulting from the triple coincidence experiment shown in figure BLIP. 10. True triple coincidences are superimposed on a imifomi background and tliree walls corresponding to two electron correlated events with a randomly occurring third electron.

The molecular beam and laser teclmiques described in this section, especially in combination with theoretical treatments using accurate PESs and a quantum mechanical description of the collisional event, have revealed considerable detail about the dynamics of chemical reactions. Several aspects of reactive scattering are currently drawing special attention. The measurement of vector correlations, for example as described in section B2.3.3.5. continue to be of particular interest, especially the interplay between the product angular distribution and rotational polarization. 

In order to make END better suited to the application of low energy events it is important to include an explicitly correlated description of the electron dynamics. Therefore multiconfigurational [25] augmentations of the minimal END are under development.
