Method of manufacturing an overwrapped pressure vessel
A pressure vessel of the type wherein a metallic liner in the shape of a cylindrical portion with a dome-shaped portion at each end thereof is overwrapped by a plurality of layers of resin coated, single fiberglass filaments. A four-step wrapping technique reinforces the vessel with overwrap material at the most likely areas for vessel failure. Overwrapping of the vessel is followed by a sizing pressurization cycle which induces a compressive prestress into the liner and thereby permits the liner to deform elastically through an increased strain range
Isaac McCoy : His Plan of and Work For Indian Colonization.
Several books and articles have been written concerning Isaac McCoy, but as far as I am able to find out there has been no book, article, or research paper written on the plan of Indian colonization that originated with McCoy, and his work for the fulfillment of that plan

Letter from J. Emory & B. Waugh to James B. Finley
John Emory and Beverly Waugh [book agents appointed to the Methodist Book Concern,1828-1832] send an invoice to Finley for $29.77. This account for subscriptions to the 1824 and 1825 Methodist Magazine is still open and needs to be closed. If someone else is responsible for payment, Emory and Waugh ask Finley to let them know.

Increasing Pilots Understanding of Future Automation State an Evaluation of an Automation State and Trajectory Prediction System
A pilot in the loop flight simulation study was conducted at NASA Langley Research Center to evaluate a trajectory prediction system. The trajectory prediction system computes a five-minute prediction of the lateral and vertical path of the aircraft given the current and intent state of the automation. The prediction is shown as a graphical representation so the pilots can form an accurate mental model of the future state. Otherwise, many automation changes and triggers are hidden from the flight crew or need to be consolidated to understand if a change will occur and the exact timing of the change. Varying dynamic conditions like deceleration can obscure the future trajectory and the ability to meet constraints, especially in the vertical dimension. Current flight deck indications of flight path assume constant conditions and do not adequately support the flight crew to make correct judgments regarding constraints. The study was conducted using ten commercial airline crews from multiple airlines, paired by airline to minimize procedural effects. Scenarios spanned a range of conditions that provided evaluation in a realistic environment with complex traffic and weather conditions. In particular, scenarios probed automation state and loss of state awareness. The technology was evaluated and contrasted with current state-of-the-art flight deck capabilities modeled from the Boeing 787. Objective and subjective data were collected from aircraft parameters, questionnaires, audio/video recordings, head/eye tracking data, and observations. This paper details findings about the trajectory prediction system including recommendations about further study
