The aviation industry is facing the challenge of reducing fossil fuels and emissions. Fuel efficiency improved by making efficient powerplant systems lighter aircraft. Modern passenger aircraft utilize polymeric composite materials to achieve structures without compromising strength. European Union already has legislation prevent landfilling increase use recyclable in automotive industry. While...

We describe a multi-modal unscented Kalman filter developed for estimation of aircraft position, velocity and heading from noisy surface surveillance data. The raw data is composed of tracks generated by the Airport Surface Detection Equipment, Model-X at Boston Logan International Airport, and is obtained from the Runway Status Lights system. The multi-modal filter formulation facilitates esti...

In recent years, performance-based contracting (PBC) has emerged as an e¤ective means to align the incentives of the …rms engaged in after-sales repair and maintenance services of highvalued and customized products, such as industrial equipment and aircraft. In particular, PBC has proved to promote improvement of product reliability, an important determinant of product performance. However, idi...

In this paper, we model the method in which aircraft survivability equipment suites successfully choose their countermeasures, and experiment with their autonomous decision-making against threats in various electronic warfare settings. We have designed and implemented our simulators to estimate the operational effectiveness of the aircraft survivability equipment suite. We formulate the operati...

The West Africa Ebola virus (EBOV) outbreak has highlighted the need for effective disinfectants capable of reducing viral load in a range of sample types, equipment and settings. Although chlorine-based products are widely used, they can also be damaging to equipment or apparatus that needs continuous use such as aircraft use for transportation of infected people. Two aircraft cleaning solutio...

a few years after the implementation of computerize maintenance management systems (cmms), showing the analysis results of the collected data in these systems is necessary and important for continuing the usage of these systems. equipment downtime and cost data can identify patterns of equipment faults and equipment costs. it can also show deficiencies in the implementation of maintenance syste...
