Abstract Hot deformation tests of 5CrNiMoV steel were performed at temperatures 700 to 870 °C and strain rates 0.001 0.1 s −1 using the DIL 805D thermomechanical simulator. The critical volume fraction models Dynamic Recrystallization (DRX) constructed based on work hardening theory. results showed that DRX decreases with increasing temperature decreasing rate, which implies occurs easily highe...

This work present a novel evaluation framework for topic extraction over user generated contents. The motivation of this work is the development of systems that monitor the evolution of opinionated topics around a certain entity (a person, company or product) in the Web. Currently, due to the effort that would be required to develop a gold standard, topic extraction systems are evaluated qualit...

We describe the location and general properties of nine human visual field maps. The cortical location of each map, as well as many examples of the eccentricity and angular representations within these maps, are shown in a series of images that summarize a large set of functional MRI data. The organization and properties of these maps are compared and contrasted with descriptions by other inves...

This work proposes an extension of Bing Liu’s aspect-based opinion mining approach in order to apply it to the tourism domain. The extension concerns with the fact that users refer differently to different kinds of products when writing reviews on the Web. Since Liu’s approach is focused on physical product reviews, it could not be directly applied to the tourism domain, which presents features...

The goal of a data warehouse is to integrate applications at the data level. Data warehouse architectures are developing in response to our increasing data and information requirements. The traditional notion of data warehouses is evolving into a federated warehouse augmented by a set of processes and services to support integrated and consistent access to heterogeneous, decentralized warehouse...
