Aviation risk perception: a comparison between experts and novices
(Wiley-Blackwell Publishing, 2004)This article describes an exploratory investigation of the risk perceptions of experts and novices in relation to helicopter operations, under conditions where the participants are matched on various characteristics ... -
Efficient solution of the combined-field integral equation with the parallel multilevel fast multipole algorithm
(2007)We present fast and accurate solutions of large-scale scattering problems formulated with the combined-field integral equation. Using the multilevel fast multipole algorithm (MLFMA) parallelized on a cluster of computers, ... -
Fast and accurate solutions of scattering problems involving dielectric objects with moderate and low contrasts
(2007)We consider the solution of electromagnetic scattering problems involving relatively large dielectric objects with moderate and low contrasts. Three-dimensional objects are discretized with Rao-Wilton-Glisson functions and ... -
Flight network-based approach for integrated airline recovery with cruise speed control
(Institute for Operations Research and the Management Sciences (I N F O R M S), 2017)Airline schedules are generally tight and fragile to disruptions. Disruptions can have severe effects on existing aircraft routings, crew pairings, and passenger itineraries that lead to high delay and recovery costs. A ... -
An integrated approach for airline scheduling, aircraft fleeting and routing with cruise speed control
(Elsevier, 2016)To place an emphasis on profound relations among airline schedule planning problems and to mitigate the effect of unexpected delays, we integrate schedule design, fleet assignment and aircraft routing problems within a ... -
İstanbul - İskenderiye uçuşu ve Mehmet Fethi Bey
(Bilkent University, 2018)Bu projede 1914 yılında İstanbul-İskenderiye (Mısır) arasında düzenlenen hava seyahati, hava seyahatinin öne çıkan ismi Yüzbaşı Mehmet Fethi’nin uçuşu üzerinden işlenecektir. Bu uçuş günümüzde dahi birçok ... -
Memory-efficient multilevel physical optics algorithm for fast computation of scattering from three-dimensional complex targets
(2007)Multilevel physical optics (MLPO) algorithm provides a speed-up for computing the physical-optics integral over complex bodies for a range of aspect angles and frequencies. On the other hand, when computation of the RCS ... -
MLFMA solutions of transmission problems Involving realistic metamaterial walls
(2007)We present the solution of multilayer metamaterial (MM) structures containing large numbers of unit cells, such as split-ring resonators. Integral-equation formulations of scattering problems are solved iteratively by ... -
Piloted evaluation of a control allocation technique to recover from pilot-induced oscillations
(American Institute of Aeronautics and Astronautics Inc., 2015)This paper describes the maturation of a control allocation technique designed to assist pilots in recovery from pilot-induced oscillations. The control allocation technique to recover from pilot-induced oscillations is ... -
RCS study of cylindrical cavity-backed apertures with outer or inner material coating: the case of E-polarization
(IEEE, 1993)Cavity-backed apertures (CBA) are encountered as parts of any airborne or spaceborne radar targets. Most familiar of them are, probably, air inlets and engine tubes, known to contribute a great deal to radar cross section ... -
Sequential and parallel preconditioners for Large-scale integral-equation problems
(2007)For efficient solutions of integral-equation methods via the multilevel fast multipole algorithm (MLFMA), effective preconditioners are required. In this paper we review appropriate preconditioners that have been used for ...
