Metallography - A Powerful Instrument for Material Characterisation, Material Development and Failure Analysis

A Common Weight Data Envelopment Analysis Approach for Material Selection

Material selection is one of the major problems in manufacturing environments since the improper selected material may lead to fail in the production processes and result in customer dissatisfaction and cost inefficiency. Every material has different properties which should be considered as major criteria during the material selection procedure. Selection criteria could be quantitative or quali...

English Language Teaching Material Development

The goal of language programs is to utilize language for effective communication. Due to the needs, interests, and motivations of language learners, they may show individual differences in their lan- guage learning. Materials used in language programs can be instructional, experiential, elucidative, or exploratory in that they can inform learners about the language, provide experience of the la...

Material Development and English for Academic Purposes Word Lists; a Reductionist Approach

Nagy (1988) states that vocabulary is a prerequisite factor in comprehension. Drawing upon a reductionist approach and having in mind the prospects for material development, this study aimed at creating an English for Academic Purposes Word List (EAPWL). The corpus of this study was compiled from a corpus containing 6479 pages of texts, 2,081,678 million tokens (running words) and 63825 types (...

Study of Material DestrultioYDuring Powerful Plasma Exposure

Influence of modeling material on undercut slope failure mechanism

A series of physical modeling tests were conducted by means of a beam type geotechnical centrifuge machine in order to investigate the drainage impact on the slope failure mechanism under centrifugal acceleration. Meanwhile, the phenomenon of stress redistribution in undercut slopes and the formation of arching effect were studied. For this purpose, a poorly graded sandy soil (Silica sand No. 6...
