The E802 Data Acquisition Complex

Complex-Valued Data Envelopment Analysis

Data Envelopment Analysis (DEA) is a nonparametric approach for measuring the relative efficiency of a decision making units consists of multiple inputs and outputs. In all standard DEA models semi positive real valued measures are assumed, while in some real cases inputs and outputs may take complex valued. The question is related to measuring efficiency in such cases. As far as we are aware, ...

Complex Correction of Data Acquisition Channels Using FIR Equalizer Filters

The common conviction about FIR (finite impulse response) digital filters is that the number of necessary taps, to reach the same performance as provided by IIR (infinite impulse response) digital filters, is usually too large. Moreover, the standard FIR filter design algorithm (Remez exchange) allows the design of linear-phase filters only. Therefore, IIR filters are often preferred over FIR o...

Resampling Methods in Complex Survey Data

Data Acquisition in the ICU

For the past four years, we have been part of the US Army’s Hospital of the Future program and have been investigating ways to address some of the remaining problems with a focus on “systems of monitors”. We are working with a wide group of collaborators to help develop the Integrated Clinical Environment (ICE) standard that is being promoted by Dr. Julian Goldman and the Medical Device Plug-an...

Complex System Governance for Acquisition

As acquisition processes have become more complex, they appear to no longer be governable by traditional approaches. Missed budgets, delayed deliveries, and expensive canceled systems appear to becoming more prevalent. Numerous investigations have been conducted attempting to elicit the factors that prevented success. Those systems that succeed in terms of usability, budget, and delivery schedu...
