Uniform linear array (ULA)-based tapped-delay line (TDL) structure has good performance metrics when the signal sources are located at the middle angles. It offers poor performance when the signal sources are close to the array endfire. In this paper, a new approach is proposed which offers higher performance and desired beamforming on TDL structure when the wideband uncorrelated radio sources ...

Errors in computer systems can cause abnormal behavior and degrade data integrity and system availability. Fault avoidance techniques such as radiation hardening and shielding have been the major approaches to protecting the system from transient errors, but these techniques are expensive. Recently, unhardened Commercial Off-The-Shelf (COTS) components have been investigated for a low cost alte...

Case, Quigley and Shiller (2005, 2013) quantified stock versus housing wealth effects on quarterly state-level retail sales, which they interpret as an approximate measure of household consumption spending. We investigate the variation of these wealth effects with the persistence of each kind of wealth fluctuation in an estimated linear dynamic fixed-effects model, allowing for both cointegrati...
