Rare earth elements (REE) naturally occur at trace levels in natural systems but, due to their increasing use modern technologies, they are now released into the environment, and considered as emerging contaminants. Therefore, development of numerical predictive models speciation various physico-chemical conditions is required predict behavior, transport potentially toxic effects on ecosystems....

Nonmonotonic inheritance is a fundamental feature of object-oriented data models. In this paper, we extend XML Schema with nonmonotonic inheritance due to its powerful modeling ability to support multiple inheritance, overriding of elements or attributes inherited from super-elements, blocking of the inheritance of elements or attributes from super-elements, and conflict handling. Another key f...

Current standards in microscopic modeling lack the ability to address certain traffic scenarios, the ability to capture discrete differences in driver behavior that exist between various driving populations, and are structured in such a fashion that various vehicle movements are predicted and modeled separately. In this study, effect of social traffic behavior on rate of traffic violation of ...

the purpose of this research is to predict knowledge sharing through dimensions of social capital. knowledge sharing occurrence depends directly upon tendency of knowledge holder to sharing as well as knowledge receiver to take it from holders. in other side, social capital is defined as linkage among people and their unifying factors such as trust. in this research, social capital is conceptua...

The paper presents the numerical results on gas-dynamic processes in various elements of impulse ejector, including pre-chamber, supersonic nozzle and mixing chamber, to determine optimal geometric parameters providing given flow rate characteristics. At an extra-high pressure ejecting gas (>100 bar) it is impossible create a design with continuously changing cross-sectional area limited len...
