DOI: 10.1002/cem.2975
Abstract: Multivariate curve resolution techniques try to estimate physically and/or chemically meaningful profiles underlying a set of chemical or related measurements. However, the estimation of profiles is not generally unique and it is often complicated by… read more here.

DOI: 10.1002/qj.3314
Abstract: In this work, we propose a method to generate an ensemble of equiprobable fields of rain occurrence at high resolution (1 degrees/16 and 30 min) using a satellite observational constraint. Satellite observations are used to… read more here.

DOI: 10.1007/s00024-020-02443-x
Abstract: The axial constraint is an important constraint for the inversion of gravity data with which the dip information of the target geological bodies can be incorporated effectively. However, poor selection of the dip angles would… read more here.

DOI: 10.1007/s00211-021-01209-4
Abstract: We propose and analyze a class of robust, uniformly high-order accurate discontinuous Galerkin (DG) schemes for multidimensional relativistic magnetohydrodynamics (RMHD) on general meshes. A distinct feature of the schemes is their physical-constraint-preserving (PCP) property, i.e.,… read more here.

DOI: 10.1007/s00332-017-9406-1
Abstract: We derive an optimal control formulation for a nonholonomic mechanical system using the nonholonomic constraint itself as the control. We focus on Suslov’s problem, which is defined as the motion of a rigid body with… read more here.

DOI: 10.1007/s00500-017-2603-x
Abstract: Bi-objective constraint-handling technique may be one of the most promising constraint techniques for constrained optimization problems. It regards the constraints as an extra objective and using Pareto ranking as selection operator. These algorithms achieve a… read more here.

DOI: 10.1007/s10489-018-1182-6
Abstract: We consider the problem of mining web access patterns with super-pattern constraint. This constraint requires that the sequential patterns in the sequence database must contain a particular set of patterns as sub-patterns. One common application… read more here.
