The relevance of introducing a requirements management system in the production process of the aircraft engine construction industry

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение
It is necessary to have access to documents containing product requirements during the design process. Search and processing of this data slows down the product design significantly.

Experimental Design for the LATOR Mission

, 2004
This paper discusses experimental design for the Laser Astrometric Test Of Relativity (LATOR) mission. LATOR is designed to reach unprecedented accuracy of 1 part in 10^8 in measuring the curvature of the solar gravitational field as given by the value ...

Nonlinear Matroid Optimization and Experimental Design [PDF]

, 2007
We study the problem of optimizing nonlinear objective functions over matroids presented by oracles or explicitly. Such functions can be interpreted as the balancing of multi-criteria optimization. We provide a combinatorial polynomial time algorithm for

Two polynomial representations of experimental design

, 2007
In the context of algebraic statistics an experimental design is described by a set of polynomials called the design ideal. This, in turn, is generated by finite sets of polynomials.

Optimization of fuel distribution in the afterburner of a gas turbine engine

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2018
The use of 3-D simulation programs and in particular NX and ANSYS simulators brought the design and fine tuning of gas turbine engine combustion chambers to the next level, as it allows improving the performance (increased combustion efficiency, reduced ...

Experimental Design of a Prescribed Burn Instrumentation

, 2018
Observational data collected during experiments, such as the planned Fire and Smoke Model Evaluation Experiment (FASMEE), are critical for progressing and transitioning coupled fire-atmosphere models like WRF-SFIRE and WRF-SFIRE-CHEM into operational use.

Experimental Design of Electrocoagulation and Magnetic Technology for Enhancing Suspended Solids Removal From Synthetic Wastewater [PDF]

, 2014
Design of experiments (DOE) is one of the statistical method that is used as a tool to enhance and improve experimental quality. The changes to the variables of a process or system is supposed to give the optimal result (response) and quite satisfactory.
