this study was conducted in order to investigate the influence of plastic deformation on the transformation of retained austenite in a trip steel with a high content of al and a low content of si. to the aim, appropriate treatments were used to produce the starting material (trip steel). the microstructure of the obtained steel was composed of bainite and phases including ferrite and retained a...

Hydropower will become an important power source of China’s grids oriented to carbon neutral. In order fully exploit the potential water resources and achieve low-carbon operation, this paper proposes approximate dynamic programming (ADP) algorithm for unit-based short-term small hydropower scheduling (STSHS) framework considering hydro unit commitment, which can accurately capture physical ope...

At present, there are no signs that global overweight and obesity rates are declining adding millions of more every year to suffer from uncontrolled body weight conditions. Conventional thinking of weight management is solely...

Simulation models have proved to be useful for examining the performance of different system configurations and/or alternative operating procedures for complex logistic or manufacturing systems. However, when applying simulation techniques to increase the performance of those systems, several limitations arise due to their inability to evaluate more than a fraction of the immense range of optio...

PURPOSE To systematically evaluate the survival and success of screw- versus cement-retained implant crowns. MATERIALS AND METHODS The authors performed an electronic search of nine databases using identical MeSH phrases. Systematic evaluation and data extraction of the articles from 1966 through 2007 were completed by three reviewers and two clinical academicians. The major outcome variable ...

network effects, increase in the value of consuming a product if many other consumers use the same product, is a feature of many markets of high-technology products. frequently cited examples of products exhibiting network effects are telecommunication or software products. this research explores the role of network effects in the consumer´s choice of mobile operator in tehran. for our empirica...

The use of various forms of contracts, like preconditions, are increasingly receiving more attention within Microsoft. This talk describes the design of Spec#, an experimental superset of the language C#, including preand postconditions and object invariants. Spec# gives rise to dynamic checks of contracts. The contracts can also be checked statically using the automatic checker Boogie. The tal...
