Trajectory simulations are tools to compute the flight path and flight parameters of munitions. We present an ontology-based object-oriented reuse infrastructure and discuss the underlying model driven development methodology. The strategic objective is to make domain knowledge and software reusable across a wide variety of trajectory simulation projects.

Domain analysis for Reusable Trajectory Simulation Durak, Umut; Mahmutyazicioǧlu, Gökmen; Oğuztüzün, Mehmet Halit S. (2005-12-01) Trajectory simulations can be regarded as computational tools to calculate the flight path and other flight parameters of munitions. They have a wide range of uses from concept formation to training simulator construction throughout the lifecycle of a weapons system. Trajectory simulations differ widely with respect to their performance and fidelity characteristics. From our observations, it is a common practice in the industry that developments of these simulations are carried out as isolated projects alth...
Effects of using different boundary conditions and computational domain dimensions on modeling and simulations of periodic metamaterial arrays in microwave frequencies Turkmen, Oznur; EKMEKÇİ, Evren; Sayan, Gönül (Wiley, 2013-07-01) This article aims to demonstrate the effects of using different boundary conditions and different computational volume dimensions in numerical simulations of periodic metamaterial arrays. A double band metamaterial unit cell design will be utilized to show that use of different boundary conditions may result in simulation of dissimilar periodic array topologies with completely different electromagnetic responses. It will also be shown that dimensions of the computational volume may strongly affect the overa...
Towards interoperable and composable trajectory simulations: an ontology-based approach Durak, U.; Oğuztüzün, Mehmet Halit S.; Algin, C. Koksal; Ozdikis, O. (Informa UK Limited, 2011-08-01) Trajectory simulation is a software module that computes the flight path and flight parameters of munitions. It is used throughout the engineering process, including simulations for studying the design trade-offs, to mission simulations for defended area analysis. In this wide application domain, reuse has always been one of the challenges of the trajectory simulation community. We apply an ontology-based simulation development methodology to fulfil the functional requirements of a trajectory simulation whi...
Kinematic Model-Based Human Detectors for Multi-Channel Radar GÜRBÜZ, SEVGİ ZÜBEYDE; Melvin, William L.; Williams, Douglas B. (2012-04-01) Humans are difficult targets to detect because they have small radar cross sections (RCS) and move at low velocities. Consequently, they are masked by Doppler spread ground clutter generated by the radar bearing platform motion. Furthermore, conventional radar-based human detection systems employ some type of linear-phase matched filtering, whereas most human targets generate a highly nonlinear phase history. This work proposes an enhanced, optimized, nonlinear phase (EnONLP) matched filter that exploits kn...
Two-level composite wing structural optimization using response surfaces Liu, B; Haftka, RT; Akgun, MA (Springer Science and Business Media LLC, 2000-10-01) A two-level optimization procedure for composite wing design subject to strength and buckling constraints is presented. At wing-level design, continuous optimization of ply thicknesses with orientations of 0 degrees, 90 degrees, and +/-45 degrees is performed to minimize weight. At panel level, the number of plies of each orientation (rounded to integers) and inplane loads are specified, and a permutation genetic algorithm is used to optimize the stacking sequence in order to maximize the buckling load. The...
