A Technique for Disinfection of the MDO Oxygen Electrode
Acta Anaesthesiologica Scandinavica, 1980A method for disinfection and aseptic assembly of the MDO (Mehrdraht Dortmund Oberfläche) oxygen electrode has been evaluated. The method is based on treating each electrode component separately and then assembling the different parts under aseptic surgical conditions.

Aerostructural interaction in a collaborative MDO environment
AIP Conference Proceedings, 2014The work presents an approach for aircraft design and optimization, developed to account for fluid-structure interactions in MDO applications. The approach makes use of a collaborative distributed design environment, and focuses on the influence of multiple physics based aerostructural models, on the overall aircraft synthesis and optimization.

Phase Transitions, 1993
Abstract According to the definition by Dornberger-Schiff (1982), a member πo of a given family of polytypes interpreted as an OD family, is called an MDO polytype, if it is impossible to construct another polytype π1 of the same family, in which the kinds of n-tuples of consecutive layers for some numbers n constitute only a selection of the kinds of ...

Aircraft loads methodology for MDO
19th AIAA Applied Aerodynamics Conference, 2001A methodology is presented for developing a complete set of aircraft loads to be used in the structural optimization of an aircraft wing during preliminary design. Using the software program ASTROS as the platform, a typical mid-size 100+ seat passenger aircraft was selected as the subject of the study.

Recent Advances in Relativistic MDOs
2019 International Vacuum Electronics Conference (IVEC), 2019The relativistic magnetron is the most compact and efficient high-power microwave (HPM) source. It has been researched since Bekefi's pioneering work in 1975 at MIT. The performance of the relativistic magnetron did not dramatically improve until the $\pmb{2000}\mathbf{s}$ when new cathode concepts were introduced independently by researchers at the ...

Controllable Axial Overmoding in an MDO
IEEE Transactions on Plasma Science, 2012During a computational investigation of a magnetron utilizing a diffraction output, it was discovered that axial overmoding allowed more than one π mode to exist. Further investigation led to the identification of at least four distinct π modes, each with its own frequency and associated 2π/3 and 4π/3 modes, each accessible by appropriate choices of ...

The role of MDO within aerospace design and progress towards an MDO capability
7th AIAA/USAF/NASA/ISSMO Symposium on Multidisciplinary Analysis and Optimization, 1998This paper reviews recent progress made in MDO within the European aerospace industry through the activities of a sequence of international collaborative partnerships of increasing complexity. Firstly, a definition of MDO is provided and its function as a key tool in the context of concurrent engineering is discussed.

Aerodynamics-structures interaction in MDO
7th AIAA/USAF/NASA/ISSMO Symposium on Multidisciplinary Analysis and Optimization, 1998This paper investigates the sensitivity of the aeroelastic analysis of aerospace structures to the aerodynamic analysis theory employed. Three similar potential flow aerodynamic analysis theories are applied in the aeroelastic analysis of several configurations.

The Study of Reliability in MDO of Aircraft
Applied Mechanics and Materials, 2012MDO and reliability design are independently processed in the traditional aircraft design. The designs process is thus consuming compute intensive, so that integrated design of MDO and reliability is required. To achieve the integration, there are two problems needed to be solved.
