Under GASB Statement 68, the DPFP plan reported a net pension liability (NPL) for the combined and supplemental plans of $6.3 billion and $23 million, respectively, as of Dec.
In response to a steady weakening of the DPFP plan--attributable primarily to issues associated with the deferred retirement option program (DROP) feature--the Texas Legislature in its 2017 regular session approved legislation (HB 3158) that made a number of noteworthy changes to the DPFP plan.
The city received an actuarial analysis of the DPFP plan performed by Deloitte Consulting LLP.
However, the increasing annual pension contributions that are mandated by the reforms to the DPFP plan will challenge the city's budget management practices for the foreseeable future.
The fiscal 2018 budget-year one of a biennial budget adopted by the city for the first time-is operationally balanced despite materially larger DPFP pension contributions.
To fit the coupler into the physical space provided by the DPFP feed network, it was mapped into the orange structure shown in Figure 2(b).
Within the aforementioned time multiplexing reception scheme, the application of DPFP antenna can be enabled in the following three steps:
Before applying the beam forming algorithm, a calibration is necessary for the DPFP antenna ports.
During the calibrations, the received signals from different ports of the DPFP antenna are measured using the LeCroy 104Xi oscilloscope, The received signals are digitized and transformed, using FFT, into frequency domain, resulting in the channel transfer function denoted by [H.sub.1], [H.sub.2], [H.sub.3] and [H.sub.4], respectively, shown in Figure 5(a).
It should be pointed out that the channels mentioned here refer to a chain of components: dipole antenna, free propagation path, the DPFP antenna system and the receiver, which are located between the two reference planes, i.e., z = 1.7 m and reference plane, in Figure 3.
The electric field [[??].sub.0]([theta],[phi]) arrives at the DPFP antenna, as shown in Figure 6, the received signals at Ports [A.sub.1], [A.sub.2], [A.sub.3] and [A.sub.4] can be described by
