Time-Delay Interferometry (TDI) is the data processing technique that cancels large laser phase fluctuations affecting heterodyne Doppler measurements made by unequal-arm space-based gravitational wave interferometers. The space of all TDI combinations was first derived under simplifying assumption a stationary array, for which three time-delay operators commute. In this model, any element can ...

We present the Time Lag/Delay Reconstructor (TLDR), an algorithm for reconstructing velocity delay maps in Maximum A Posteriori framework reverberation mapping. Reverberation mapping is a tomographical method studying kinematics and geometry of broad-line region active galactic nuclei at high spatial resolution. Leveraging modern image reconstruction techniques, including Total Variation Compre...

In the field of management, the delay within projects is a prominent and contentious issue. Due to the fact that delay leads to cost and time over-runs, it is often the subject of litigation claims and creation of managerial tensions. In a bid to bring such delays under control and also to diminish managerial tensions, it is necessary to recognize and understand the following four concepts:"typ...

In recent years, breakthroughs in methods and data have enabled gravitational time delays to emerge as a very powerful tool measure the Hubble constant $H_0$. However, published state-of-the-art analyses require of order 1 year expert investigator up million hours computing per system. Furthermore, precision improves, it is crucial identify mitigate systematic uncertainties. With this delay len...
