Hot deformation behavior of micro-alloyed steel using processing maps developed with different constitutive equations [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2022 The hot workability of microalloyed steel was studied in the deformation temperature range of 850–1200ºC and strain rate of 0.001-100s-1. The constitutive relation of flow stress with temperature, strain rate and strain was established to construct ...

Query processing of spatial objects: Complexity versus Redundancy [PDF]
, 1993 The management of complex spatial objects in applications, such as geography and cartography, imposes stringent new requirements on spatial database systems, in particular on efficient query processing. As shown before, the performance of spatial query

A cutting process for random mappings [PDF]
Random Structures & Algorithms, 2006 AbstractIn this paper we consider a cutting process for random mappings. Specifically, for 0 <m<n, we consider the initial (uniform) random mapping digraphGnonnlabeled vertices, and we delete (if possible), uniformly and at random,mnoncyclic directed edges fromGn.
