RELATIONSHIP BETWEEN MICROSTRUCTURE, MECHANICAL PROPERTIES AND DISLOCATION SUBSTRUCTURES IN A MULTIPHASE STEEL

by A. J. Abdalla, T. M. Hashimoto, C. Moura, Neto M. S. Pereira , 2004
"... This paper discusses the formation of microstructures with different volume fractions, as an outcome from a specific heat treatment, with the following phases: ferrite, martensite, bainite and retained austenite. For the microstructure characterization we developed a chemical etching that allows us ..."
Abstract - Add to MetaCart
to distinguish the phases by optical microscopy. The process was also accomplished by scanning electron microscopy with the objective of analyzing the active mechanisms of fracture and transmission electron microscopy with the aim of determining the dislocation substructures formed during the fatigue test

Systematic benchmark of substructure search in molecular graphs -- From Ullmann to VF2

by Hans-christian Ehrlich, Matthias Rarey , 2012
"... Background: Searching for substructures in molecules belongs to the most elementary tasks in cheminformatics and is nowadays part of virtually every cheminformatics software. The underlying algorithms, used over several decades, are designed for the application to general graphs. Applied on molecula ..."
Abstract - Add to MetaCart
on molecular graphs, little effort has been spend on characterizing their performance. Therefore, it is not clear how current substructure search algorithms behave on such special graphs. One of the main reasons why such an evaluation was not performed in the past was the absence of appropriate data sets

Lecture Notes on Substructural Operational Semantics 15-816: Linear Logic

by Frank Pfenning , 2012
"... In this lecture we view the operational semantics of a programming language as a stateful system with some transitions. This suggests we should be able to describe it in linear logic in a way that is analogous to the early examples used in this class, like blocks world. Since we use linear logic to ..."
Abstract - Add to MetaCart
to describe operational semantics, we could use the term linear operational semantics to describe this technique. It turns out that other substructural logics, like ordered logic [PS09] or affine logic are often more appropriate, so we refer to it more generally as substructural operational semantics [Pfe04

Performance Evaluation of Some Clustering Algorithms and Validity Indices

by Ujjwal Maulik, Sanghamitra B - IEEE Transactions on Pattern Analysis and Machine Intelligence , 2002
"... Abstract—In this article, we evaluate the performance of three clustering algorithms, hard K-Means, single linkage, and a simulated annealing (SA) based technique, in conjunction with four cluster validity indices, namely Davies-Bouldin index, Dunn’s index, Calinski-Harabasz index, and a recently de ..."

developed index I. Based on a relation between the index I and the Dunn’s index, a lower bound of the value of the former is theoretically estimated in order to get unique hard K-partition when the data set has distinct substructures. The effectiveness of the different validity indices and clustering

A Protein Substructure Based P System for Description and Analysis of Cell Signalling Networks

by Thomas Hinze, Thorsten Lenser, Peter Dittrich - In
"... Abstract. The way how cell signals are generated, encoded, transferred, modified, and utilised is essential for understanding information process-ing inside living organisms. The tremendously growing biological knowl-edge about proteins and their interactions draws a more and more de-tailed image of ..."
Abstract - Cited by 6 (5 self) - Add to MetaCart
to be appropriate to this. We utilise string-objects to carry information about protein binding domains and their ligands. Embedding these string-objects into a deterministic graph structured P system with dynamical behaviour, we introduce a model that can de-scribe cell signalling pathways on a submolecular level

A Note On Substructuring Preconditioning For Nonconforming Finite Element Approximations Of Second Order Elliptic Problems

by Serguei Maliassov
"... this paper an algebraic substructuring preconditioner is considered for nonconforming finite element approximations of second order elliptic problems in 3D domains with a piecewise constant diffusion coefficient. Using a substructuring idea and a block Gauss elimination part of the unknowns is elimi ..."

Modelling Spatial Substructure in Wildlife Populations using an Approximation to the Shortest Path Voronoi Diagram

by C. W. Stewart , R. Van Der Ree , 2009
"... In the field of conservation biology, accurate population models are important for managing wildlife. It has been acknowledged that spatial structure should form an integral part of such models. Advancement in the power of desktop computers has allowed biologists to construct individual-based, spat ..."
Abstract - Add to MetaCart
models, that any individual within a patch can interact with any other individual of the patch may not always be appropriate. For example, in social species where the size of the social group home range is much smaller than the average patch size, individuals in a social group from one part of the patch

Within-Population Genetic Structure in Beech (Fagus sylvatica L.) Stands Characterized by Different Disturbance Histories: Does Forest Management Simplify Population Substructure?

by Andrea Piotti, Stefano Leonardi, Myriam Heuertz, Joukje Buiteveld, Thomas Geburek, Sophie Gerber, Koen Kramer, Cristina Vettori
"... The fine-scale assessment of both spatially and non-spatially distributed genetic variation is crucial to preserve forest genetic resources through appropriate forest management. Cryptic within-population genetic structure may be more common than previously thought in forest tree populations, which ..."

Archives of Computational Methods in Engineering manuscript No. (will be inserted by the editor) Variational-Based Reduced-Order Model in Dynamic Substructuring of Coupled Structures Through a Dissipative Physical Interface: Recent Advances

by R. Ohayon, C. Soize, R. Sampaio, R. Ohayon, C. Soize, R. Sampaio , 2014
"... Abstract This paper deals with a variational-based reduced-order model in dy-namic substructuring of two coupled structures through a physical dissipative flex-ible interface. We consider the linear elastodynamic of a dissipative structure com-posed of two main dissipative substructures perfectly co ..."

in dynamic substructuring. It consists in constructing a reduced-order model using the free-interface elastic modes of the two main substructures and, for the linking substructure, an appropriate frequency-independent elastostatic lifting operator and the frequency-dependent fixed-interface vector basis.

Bayesian Metanetwork for Modelling User Preferences in Mobile Environment

by Vagan Terziyan, Ra Vitko - In: Proceedings of KI 2003: Advances in Artificial Intelligence, Lecture Notes in Artificial Intelligence , 2003
"... Abstract. The problem of profiling and filtering is important particu-larly for mobile information systems where wireless network traffic and mobile terminal’s size are limited comparing to the Internet access from the PC. Dealing with uncertainty in this area is crucial and many re-searchers apply ..."

The extra level(s) in the Metanetwork is used to select the appropriate substructure from the basic network level based
