Optimising a nonlinear utility function in multi-objective integer programming
Melih Ozlen, Meral Azizoğlu, Benjamin A. Burton
In this paper we develop an algorithm to optimise a nonlinear utility function of multiple objectives over the integer efficient set. Our approach is based on identifying and updat…
Modelling trade offs between public and private conservation policies
Ascelin Gordon, William T. Langford, Matt D. White +2
To reduce global biodiversity loss, there is an urgent need to determine the most efficient allocation of conservation resources. Recently, there has been a growing trend for many…
A tree traversal algorithm for decision problems in knot theory and 3-manifold topology
Benjamin A. Burton, Melih Ozlen
In low-dimensional topology, many important decision algorithms are based on normal surface enumeration, which is a form of vertex enumeration over a high-dimensional and highly de…
Crystallization in suspensions of hard spheres: A Monte Carlo and Molecular Dynamics simulation study
Tanja Schilling, Sven Dorosz, Hans Joachim Schoepe +1
The crystallization of a metastable melt is one of the most important non equilibrium phenomena in condensed matter physics, and hard sphere colloidal model systems have been used…
Dynamics of hard-sphere suspension using Dynamic Light Scattering and X-Ray Photon Correlation Spectroscopy: dynamics and scaling of the Intermediate Scattering Function
V. A. Martinez, J. H. J Thijssen, F. Zontone +2
Intermediate Scattering Functions (ISF's) are measured for colloidal hard sphere systems using both Dynamic Light Scattering (DLS) and X-ray Photon Correlation Spectroscopy (XPCS).…
Absence of Morphotropic Phase Boundary Effects in BiFeO3-PbTiO3 Thin Films Grown via a Chemical Multilayer Deposition Method
Ashish Garg, Shashaank Gupta, Shuvrajyoti Bhattacharjee +4
Here, we report the unusual behaviour shown by the (BiFeO3)1-x-(PbTiO3)x (BF-xPT) films prepared using a multilayer deposition approach by chemical solution deposition method. Thin…
