mixed clayey soils occur as mixtures of sand (or gravel) and clay in widely varying proportions. their engineering behavior has not been comprehensively studied yet. an experimental program, comprising monotonic, cyclic, and post-cyclic triaxial tests was undertaken on compacted clay-granular material mixtures, having different proportions of clay and sand or gravel. this paper presents the res...

To completely understand wear mechanisms of mixed ceramic cutting tools (Al 2 O 3-TiC), residual stress states and the superposition of external loads during hard turning should be investigated. This can be done via X-ray diffraction using high-energy synchrotron radiation to determine lattice strains in the material. For this reason, in first model tests, strain states in mixed ceramics were d...

Although titanium/hydroxyapatite composite is an attractive material for dental implants, it would be more useful if it could be produced as a functionally graded material (FGM). In this paper, microstructure and microhardness of a five-layer titanium/hydroxyapatite functionally graded material has been investigated. First, titanium and hydroxyapatite (HA) powders were mixed with the Ti to HA v...

BDNPF/A is a useful energetic plasticizer, but mixed formal, which consists of BDNPF, DNPBF, and BDNBF, is anticipated to be better than BDNPF/A in chemically, thermally and economically. Last year, we successfully synthesized and characterized the mixed formal that has minimum contents of diformal. It is well known that the existing mixed formal always has an 8 ~ 10 % of diformal. At first, we...

The water supply is the crucial problem of human beings in the world. Earth dams are usually the most important structures to store and manage the main sources: surface waters. The safety of earth dams in different conditions especially under earthquake loadings plays a vital role in sustainable developments. Recently, mixed-clay soil is widely used as water- seal material in the core of earth ...

This paper describes experiences with quasiautomated creation of a computational ontology for maritime information from a mixed collection of source material. Based on these experiences, hypotheses and conclusions concerning the creation of computational ontologies for engineering and other technical or scientific domains are presented. Heuristics for resolving anomalies in ontologies generated...
