With this transformation, UML models could be verified by verifying derived event B models.
Previous phylogenetic hypotheses had suggested that the transition to land was a rather derived event in the history of pulmonates.
Typically, however, published cost-of-illness studies do not meet these criteria, and the derived event costs are adjusted for local differences (for example, in treatment pattern, definition of clinical event and disease severity).
For this purpose, the odds ratios (OR) and their 95% confidence intervals from the derived event rates in experimental and control group for each of the studies were calculated.
The MathWorks Inc., Natick, MA, 2005) program derived event information about upright time (time in standing and walking posture), number of upright events (number of changes from sit/lie to standing posture), and length of all upright events from all days with complete 24 h of recordings.
Third, the study relied on users' geotagged tweets to derive event related datasets.
We used International Epidemiologic Database to Evaluate AIDS (IeDEA) East African data to derive rates of CD4+% or CD4+ decline, opportunistic infections, and death through age 13 years, and data from the Cape Town AIDS Cohort to derive event risks at ages greater than 13 (Appendix) [ 21, 22].
The event table in ERS stores all received and derived traffic event information including event identity, type of traffic event, occurrence timestamp, event location, message transmission range, event reputation value, and event confidence list.
