Relaxivity of MRI contrast agents

André Merbach, Lothar Helm, Eva Jakab Toth

In the recent years Magnetic Resonance Imaging has evolved into one of the most powerfuldiagnostic techniques in medicine, in part thanks to the application of suitable contrastagents. The design of new, more efficient MRI contrast media requires the compl ...

Challenges in Large-Scale Open Agent Mediated Economies

Steven Nicolas Willmott

Technology developments such as Web Services, GRID Computing and peer-to-peer toolkits are rapidly changing the way systems deployed in public networks interact. Large-scale usage of these technologies would very likely lead to environments which have many ...

Hierarchical model for real time simulation of virtual human crowds

Daniel Thalmann

This paper describes a model for simulating crowds of humans in real time. We deal with a hierarchy composed of virtual crowds, groups, and individuals. The groups are the most complex structure that can be controlled in different degrees of autonomy. This ...

Three- and Four-Center Trans Effects in Triply Bonded Ditungsten Complexes: An ab Initio Molecular Dynamics Study of Compounds with Stoichiometry W2Cl4(NHEt)2(PMe3)2

Ursula Röthlisberger

We have performed ab initio mol. dynamics simulations based on d. functional theory to characterize the structural, electronic, and dynamic properties of the three major isomeric forms of the title compd. In agreement with exptl. results, calcns. with two ...

Predicted calcium titanate solution mechanisms in calcium aluminoferrite and related phases

Karen Scrivener

Computer simulation, using an ionic, Born-like model, is used to investigate the accommodation of titanium impurities in Ca-Al-Fe-O phases. Specifically, calcium titanate solution in Al2O3, Fe2O3, CF, C2F, CA, C(2)A, C(3)A, and C(4)AF (where C denotes CaO) ...

A paradigm for controlling virtual humans in urban environment simulations

Daniel Thalmann, Ronan Boulic

Presents a new architecture for simulating virtual humans in complex urban environments. The approach is based on the integration of six modules. Four key modules are used in order to manage environmental data, simulate human crowds, control interactions b ...

Expertness Measuring in Cooperative Learning

Masoud Asadpour

Cooperative Learning in a multi-agent system can improve the learning quality and learning speed. The improvement can be gained if each agent detects the expert agents and use their knowledge properly. In this paper, a new cooperative learning method, call ...

Conformational Equilibria of Peroxynitrous Acid in Water: A First-Principles Molecular Dynamics Study

Ursula Röthlisberger

An aq. soln. of peroxynitrous acid has been studied using first-principles mol. dynamics simulations based on d. functional theory. The relative Helmholtz energies of different conformers have been detd. via thermodn. integration with constraints. At contr ...

Ab initio molecular dynamics simulations of the gas-phase reaction of hydroxyl radical with nitrogen dioxide radical

Ursula Röthlisberger

The reaction between the hydroxyl radical and the nitrogen dioxide radical in the gas phase has been studied with ab initio mol. dynamics simulations based on d. functional theory. Nitric acid HONO2 and cis-cis peroxynitrous acid ONOOH are formed spontaneo ...

Tensile strength of titanium matrix composites: Direct numerical simulations and analytic models

William Curtin

A recently-developed model for the numerical simulation of tensile stress-strain behavior in fiber-reinforced composites is used to predict the tensile strength of a metal matrix composite consisting of a Ti-1100 matrix reinforced with SCS-6 SiC fibers. Da ...
