Geometric Perspectives on MDO and MDO Architectures
12th AIAA Aviation Technology, Integration, and Operations (ATIO) Conference and 14th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2012 Two main perspectives have been developed within the Multidisciplinary Design Optimization (MDO) literature for classifying and comparing MDO architectures: a numerical point of view and a formulation/data flow point of view. Although significant work has been done here, these perspectives have not provided much in the way of a priori information or ...

Combustion Characteristics of MDO and MDO Emulsion in Automotive Diesel Engine
Transactions of the Korean Society of Mechanical Engineers B, 2012) 배출량이 적어 운송수단, 발전설비, 플랜트 등 여러 분야에서 사용되고 있으나, 연소특성상 NOx(질소산화물) 및 Soot(미연탄소미립자)의 배출량이 문제시 되고 있다. 이를 해결하기 위한 기술로는 커먼레일 고압 연료분사, EGR(Exhaust Gas Recirculation)등의 전처리 기술과 LNT(Lean NOx Trap), DPF(Diesel Particle Filter), SCR(Selective Catalytic Reduction), 등의 후처리 기술 및 물 에멀젼 연료(Water emulsion fuel), 바이오 디젤, DME(Dimethyl Ether)등의 대체연료기술이 있다. 이러한 전처리 및 후처리 기술은

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.

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.

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.

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.

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 ...
