Incident progression analysis

System behavior analysis and prognosis can be executed by means of various procedures. The procedures generally described in the literature can be traced back to three standard types, namely failure effect analysis [4-9], fault tree analysis [4-10], and incident progression analysis [4-11], The three procedures will be discussed, as well as the concept of the decision table technique, which is also a good tool but has rarely been discussed in the literature in connection with this application. To begin, the customary analysis techniques [4-9], [4-10], [4-11] will be discussed in alphabetical order. This will serve to delineate and distinguish the procedures. 

Incident progression analysis serves to ascertain undesired events with a common specific incident trigger. 

A near miss is an unplanned occurrence that interferes with or interrupts the orderly progress of work or has the potential to cause personal injury or monetary loss through property damage. In order to prevent a future occurrence that may result in an accident, a near miss incident reporting, analysis, and documentation system is a valuable accident prevention strategy. 

In rodent stroke models, statin pretreatment has been shown to reduce infarct volumes and improve outcomes. Similarly, several clinical studies have shown that prior statin use reduced the severity of acute ischemic stroke and myocardial infarction. Recent studies indicate that beneftt can be achieved even when treatment is initiated after the onset of symptoms. In rodents, atorvastatin and simvastatin have been shown to reduce the growth of ischemic lesions, enhance functional outcome, and induce brain plasticity when administered after stroke onset. A retrospective analysis of the population-based Northern Manhattan Stroke Study (NOMASS) showed that patients using lipid-lowering agents at the time of ischemic stroke have a lower incidence of in-hospital stroke progression and reduced 90-day mortality rates. Retrospective analysis of data of the phase III citicoline trial showed... 

Very thin films exhibit special structure because of their confined geometry between substrate and surface. Their structure cannot be studied in a normal setup. In order to obtain enough photons on the detector, the X-ray beam must impinge on them under grazing incidence (Cf. Sects. 7.6.3.1,1.63.2, 8.8). This technique is suitably combined with microbeams. Current effort is focusing both on progress of the instrumentation and on the development of adapted analysis methods. 

Another type of logic tree, the event tree, is an inductive technique. Event Tree Analysis (ETA) also provides a structured method to aid in understanding and determining the causes of an incident.(i) While the fault tree starts at the undesired event and works backward to identify root causes, the event tree looks forward to display the progression of various combinations of equipment failures and human errors that result in the incident graphically. 

With increasing energy of the incident photons the photoionization process is accompanied by a rupture of valence bonds, leading to various ionized fragments, the identification of which requires complementary methods of analysis. During the last decade much progress has been achieved in the mass spectrometry of the photoionization products in various diatomic or polyatomic gases under vacuum u.v. irradiation. 

The incidence of mortality due to lung cancer in two chromate production plants in the Federal Republic of Germany was examined in relation to changes in operations and industrial hygiene over the years. The cohort consisted of 1,140 workers who were employed for at least 1 year from before 1948 to 1979. For respiratory cancer, OZE=21/10.93, SMR=192 at one plant and O/E=30/13.41, SMR=224 at the other. Analysis of SMRs over 5-year periods revealed a progressive decline at both plants (Korallus et al. 

Incident causation is assumed to progress from the bottom to the top, which means that chances for early prevention of accidents decrease as you get closer to the top. The order of incident analysis is assumed to be top-down, but with different starting points in the iceberg depending On the type (or level) of data that trigger the detection in the first place. It is also assumed that modem investigation techniques will always try to get as far to the bottom of...
