Manufactured sand differs from natural sea and river dredged sand in its physical and mineralogical properties. These can be both beneficial and detrimental to the fresh and hardened properties of concrete. This paper presents the results of a laboratory study in which manufactured sand produced in an industry sized crushing plant was characterised with respect to its physical and mineralogical...

twenty four samples of xenoliths and country rocks from the 1961 lava flow of calbuco volcano have been studied. fourteen samples have been analyzed for major elements and p, ni, ba, cr, v, zr, sc, y, and sr. five of these samples were further analyzed for sm, nd, sr, and pb isotope ratios. seventeen samples were analyzed under the microscope and three samples were analyzed by microprobe for th...

We participated in the SemEval-2007 coarse-grained English all-words task and fine-grained English all-words task. We used a supervised learning approach with SVM as the learning algorithm. The knowledge sources used include local collocations, parts-of-speech, and surrounding words. We gathered training examples from English-Chinese parallel corpora, SEMCOR, and DSO corpus. While the fine-grai...

Entity Recognition (ER) is a key component of relation extraction systems and many other natural-language processing applications. Unfortunately, most ER are restricted to produce labels from small set entity classes, e.g., person, organization, location or miscellaneous. In order intelligently understand text extract wide range information, it useful more precisely determine the semantic class...

Combining different fiber types may improve the mechanical properties of reinforced concrete. The present study is focused on investigating hybrid concrete (HFRC) with steel and basalt fiber. Mechanical fine-grained are investigated. results demonstrate that using optimal reinforcement ratios avoids mixtures’ segregation improves their homogeneity. Concrete has higher strength. Effective method...
