The mechanochemical processing of aerospace metals

A Comprehensive Set of Impact Data for Common Aerospace Metals

ABSTRACT The results of two sets of impact experiments are reported within. To assist with model development using the impact data reported, the materials are mechanically characterized using a series of standard experiments. The first set of impact data comes from a series of coefficient of restitution experiments, in which a 2 meter long pendulum is used to study “in context” measurements of ...

High-Performance Parallel Processing Aerospace Information Server

This paper focuses on development and implementation of a high-performance parallel processing information server for web based education and provision of aerospace information services. An innovative model of software architecture is presented to effectively utilize the computational power of a distributed server platform. It fulfills on-demand Internet-based client requests for astronomical i...

Aerospace Applications of Intervals: From Geospatial Data Processing to Fault Detection in Aerospace Structures

the comparative impact of prompts and recasts in processing instruction versus meaningful output-based instruction on efl learners’ writing accuracy

the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...

New Processing of Composite Grids for Aerospace Applications

Composite materials exhibit their highest stiffness and strength in unidirectional format. Any deviation from this lead to lower fiber volume fractions, and lower properties. Composites grids can be exceptionally stiff and strong if their ribs are umdircct.üii|ü. Several approaches have been published in recent years. Modeling of mull.c„cct.onal grids is simple because it follows the assumption...
