Arrival / departure : architecture of dislocation
Our identities are defined by a qualitative set of parameters that are at once universal and site specific. We are, as an old saying puts it, "products of our environment." Our knowledge and our beings are constantly being tested and changed through our interactions, both physical and cerebral, in …

Fluorescence assay for polymerase arrival rates
… characterization strategies. The RNA polymerase arrival rate (PAR) is defined to be the rate that RNA polymerases arrive at a specified location on the DNA. Designing and characterizing biological modules in terms of RNA polymerase arrival rates provides for many advantages in the construction …

Effects of reduced IFR arrival-arrival wake vortex separation minima and improved runaway operations sequencing on flight delay
(cont.) 65.6% and 67.0% and the average NAS delay by 24.3% and 24.7% relative to the FIFO and Serve-the-Longest-Queue algorithms respectively.

Source localization via time difference of arrival
… of non-cooperative sources, time difference of arrival (TDOA) of the signals received at pairs of sensors is typically employed. A two-stage localization method in multipath environments is proposed. During the first stage, TDOA of the signals received at pairs of sensors is estimated. In the …

Photon Arrival Time Quantum Random Number Generation
A quantum random number generator (QRNG) is one which re- lies on a physical process, extracting randomness from the inherent uncertainty in quantum mechanics. This is to be contrasted with current pseudo-random number generators (PRNG), which although useful, are in fact deterministic: they always …

Improving inbound visibility through shipment arrival modeling
… the underlying variation for each inbound arrival signal based on historical error rates. Our approach is to map all inbound signal sources and then create a classification-tr-e model that minimizes the joint variance of the prediction errors. Simulations indicate that such a model can be …

Direction of arrival estimation using antenna arrays
… is to design, build and evaluate a direction-of-arrival measurement system using an antenna array operating at 2050 MHz. The first phase of the project is an extensive study of various high resolution DOA estimation algorithms. The algorithms studied include subspace-based techniques such as the …

Sequential bayesian filtering for spatial arrival time estimation
… proposed. The focus here is on inversion using arrival times of identified paths within recorded time-series. After a short study of a linearization techniques employing such features and numerical issues on their implementation, we turn our attention to the need for accurate extraction of …

Predicting Future Locations and Arrival Times of Individuals
This work has two objectives: a) to predict people's future locations, and b) to predict when they will be at given locations. Current location-based applications react to the user's current location. The progression from location-awareness to location-prediction can enable the next generation of …

Decrease Arrival to CT Time to Improve Stroke Outcomes
… specific goal of the project is to decrease the arrival to t-PA treatment times to <45 minutes in > 50% of the cases. The decreased treatment time will prove to shorten the average length of stay on average by two days (Audebert & Sobesky, 2014). The goal will be accomplished by decreasing the …

Multipath arrival tracking for marine vehicles utilizing pattern recognition
… of the patterns associated with these multipath arrivals. Through the use of pattern recognition, a multipath arrival tracking algorithm was developed to utilize the unique characteristics associated with each individual ray path for long range tracking purposes. This tracking algorithm analyzes …

Advanced noise abatement approach and arrival procedures have been shown in previous studies and in limited implementation to be a cost effective means of achieving near- and medium-term noise reductions. Additionally, these procedures can be employed to reduce fuel bum, emissions, and …
