Cumulative Efficiency Web Interface (CEW)

CEW is the Cumulative Efficiency Analysis application. The application provides an indirect computation for detection efficiency at selected coils, monitors (or monitor combinations) at selected sites using a given fish population. Click here to see a formal description of the CEW analysis algorithm.

Click on the link to run the application and enter your PTAGIS username and password to log in.

There are three steps to running a CEW analysis:

1. Select the site, monitor and coil configuration
2. Select a fish population
3. Run the analyisis and view and delete the reports

For this example, we will run an efficiency report for the Bonneville Dam Juvenile Monitoring facility for all fish passing during the month of August, 2006.

Select Site, Monitor and Coil Configuration

To begin, click on the SpecifySite link to set up the site, monitor and coil configuration of interest as shown in Figure 1.

After the SpecifySite link is clicked, a submenu is presented to allow you to create (insert) a site configuration.

After you click on the Insert link to create the configuration, you will be presented with a dynamic form. Since this example will create an efficiency report for Bonneville Juvenile Monitoring Facility, we will enter BON JMF in the ceaConfigName: field and select B2J - Bonneville PH2 Juvenile as the siteCode.

Since coil configurations at interrogation sites can change over time, you are asked to select the Configuration Sequence Number, cnfgSeqNbr, of interest for this site. We will select #150 for this example.

After the site and configuration are selected, you can include all of the Antenna Groups (sometimes known as Monitors), or a subset. You can also select specific Antennas (coils) and not others. In our example we will select all of the antenna groups and all of the antennas.

When you're finished defining the antenna configuration, click on the Insert button on the top of the form.

You will see a message that the site was sucessfully inserted into the database.

Select Fish Population

To identify the fish of interest for the Cumulative Efficiency Analysis, click the SpecifyFish link on the left hand side of the page.

The menu will again expand to allow you to create or insert a new description of the fish or tag codes of interest.

The form changes to allow you to name this specification of a fish population and to specify criteria to refine your selection for the fish population of interest.

Enter "B2J August 2006 in the queryName field on the form.

Possible restrictions include Tag ID, Tag File Name, Release Hydro Unit Code, Release River Kilometer, Release Date / Time, Migration Year, Species, Run, Rearing Type or Obs Date.

Since our example is focused on the analysis of efficiencies at Bonneville smp during August, 2006, we check the ObsDate restriction.

Notice that a drop-down menu of possible ObsDate comparison operators appears.

We choose the Between operator and two fields appear. Use the date selector to choose the August first begin date and August 31st end date, or key in the correct date in the date fields.

When you're finished defining the fish population, click on the Insert button on the top of the form.

A message will display that the query definition was successfully inserted into the database.

Run the analyisis and view and delete the reports

Now that we have pinpointed a site configuration and a set of fish passing that site during certain time period, we can use these criteria to run the Cumulative Efficiency Analysis.

Click the Analyze link on the left side of the page then click the RunReport link.

Choose the B2J August 2006 fish of interest defined previously, and select the BON JMF antennas of interest from the drop down lists on the form.

Click the RunReport button to initiate the analysis. Depending upon the amount of data that must be analyzed the report may run quickly or may take more time.

Click the See Results link to see a form with your report.

To see the report, click the radio button in the SeeFile? column of the CEA Analysis Results table.

Special Case: Virtual Antenna Groups

A special feature of the CEW application allows the user to combine antennas into virtual antenna groups. This is convenient combining antennas from different antenna groups into a single group.

For example, the Bonneville Configuration has a Full Flow Monitor with antennas 01, 02, 03 and 04. Directly downstream, if the main switch gate to the Primary Bypass Flume is closed, fish will be routed to the SbyC Separator Gate Monitor. with antennas A1, A2, A3 and A4.

CEA will allow us to combine the Full Flow Monitor Coils with the SbyC Separator Gate Monitor Coils to create a virtual monitor that includes coils 01, 02, 03, 04, A1, A2, A3 and A4.

To do this, simply rename the xxxxx names on the xxxx form when you define the site configuration (Specify Site / Insert)as shown below.

The Report logic will combine all eight coils and perform the efficiency analysis on the group of eight coils as a single virtual monitor.
