The customized multiple arrays are becoming vastly used in microarray experiments for varies purposes, mainly for its ability to handle a large quantity of data and output high quality results. However, experimenters who use customized multiple arrays still face many problems, such as the cost and time to manufacture the masks, and the cost for production of the multiple arrays by costly machin...

The paper investigates the ability to learn from an aircraft accident as the opportunities for learning diminish with the decline in the accident rate. A safety compromising case is studied as the processes of aircraft accident intervention and recovery can degrade the ability of an aircraft accident investigation process to enhance aviation safety by revealing accident causation. In the case s...

We investigate whether there were common causes for the withdrawal from the regional aircraft market of three established manufacturers (BAE Systems, Fokker and Saab), while competitors thrived. We focus on the markets for 50and 100-seat aircraft. One cause concerning the 50-seat market was the introduction of a new class of aircraft, the regional jet, which pushed the less successful turboprop...

Previous economic evaluations for health care have focused mainly on the clinical and pharmacological areas. This paper presents the implementation of a methodology for economic evaluation on technological research. The case of a new prosthetics design for partial foot amputee patients was used for analysis. The aim of this work was to calculate the cost of device manufacture and to separate it...

For complex systems, such as the aircraft, the implementation of prognostics and health management (PHM) techniques can effectively improves the system performance and achieves the required reliability, safety and supportability. Traditionally, the design of the PHM system and the aircraft is often implemented separately and sequentially, which is not optimal in the view of the whole aircraft s...

The continued development of sophisticated aircraft with high fidelity control systems will enable autonomous execution of challenging tasks such as aerial refueling and close formation flight. In order to achieve such tasks in autonomous flight, an aircraft must sense other aircraft in close proximity and position itself relative to them. For example, aerial refueling requires the follower air...

The vertical stabilizer is a primary aerodynamic surface responsible for providing directional stability of an aircraft. Directional stability is further augmented by the yaw damping capability of the rudder using feedback control. When the rudder experiences faults or the vertical stabilizer is damaged, directional stability of an aircraft will be compromised. In the worst-case scenario, the v...

This paper develops and estimates a dynamic equilibrium model of the market for commercial aircraft. Airline choices are modeled as the solution to a discrete time dynamic programming problem, where in each period, each airline chooses one or more of various models of new and used aircraft. In equilibrium aircraft prices are such that no airline would benefit from buying, selling, trading or sc...
