Determining the Time-Dependent Trip Distribution in a Complex Intersection for Traffic Responsive Control by M. Cremer.

The magnitude of partial flows from each entry to any exit a complex intersection is basic information for an efficient traffic responsive control signalized intersections. However, in many cases these cannot be measured directly but must estimated vehicle counts at the entries and exits. A new method estimating presented here which not only evaluates balance equations accumulated entering leaving volumes as previous methods have done additionally makes use analysis time sequences by correlation techniques. applied simulated real data it shown that fairly good estimates are obtained even capable track variations flows. computational effort moderate may microprocessor site intersection.

Testing the dynamics of shutdown systems instrumentation in reactor trip measurements by O. Glöckler.

Abstract Periodic testing of the dynamics shutdown systems and their instrumentation is performed in CANDU nuclear power plants Ontario Power Generation (OPG) Bruce Power. Measurements in-core flux detector (ICFD) ion chamber (I/C) signals responding to insertion shut-off rods (shutdown system No. 1, SDS1), or injection neutron absorbing poison No.2, SDS2) are regularly carried out at beginning planned outages. A reactor trip manually initiated high response ICFDs I/Cs recorded by multi-channel high-speed high-resolution data acquisition set up temporarily various locations station. The sampling seaprate synchronized through headset communication total 120 station can be sampled simultaneously 2500 samples per second. effective prompt fractions estimated from measured response. Effectiveness timeline mechanism assessed measurement as well. identify with abnormally slow (under-prompt) overshooting (over-prompt) outage. time required for drop predefined pre-trip values (level crossing time) plotted a function position compared against safety requirements. propagating effect rod on monitored level times chambers.
