This toolbox computes the parameters of the Bouc–Wen–Baber–Noori hysteresis model using Multiobjective optimization evolutionary algorithms (MOBEAs). The toolbox uses the NSGA − II algorithm, which is an elitist non–dominated sorting EA. The toolbox uses the original NSGA-II algorithm developed by Prof. Kalyanmoy Deb, which can be download from: http://www.iitk.ac.in/kangal/codes.shtml Prof. Deb allowed me to use and post this toolbox. For further information about the toolbox read the documentation and the following papers: - Kalyanmoy Deb, Sameer Agrawal, Amrit Pratap, T Meyarivan.

HASEM is a c++ template library, it can be easily configure as a expression template. HASEM solves any linear equation of any kind, it might be homogenous/none homogenous, compute the inverse of square/none square matrices, find LU decomposition, find determinant and rank of matrices, calculate the characteristic polynomial of matrices, find the eigenvalues and eigen vectors and so on. HASEM uses many methods, therefore, you are not limited to just one method, you have the choice to define your desire method as default one. With over 200 member functions and over 40 none member functions HASEM is almost able to solve any linear algebra problems. HASEM support multidimensional as well, you can mix up your multidimensional matrix with other matrices with different size, and apply all operations on them as well.It's possible to save the computed matrix into files, and when required read it from files and load the data into matrices. It is also very easy to add your extension to HASEM.

ArchNURBS is a MATLAB tool for the analysis of planar curved structures, with a particular attention to masonry arches. As in CAD softwares, the geometry of the model is defined by a NURBS representation of the structure. Indeed, the user can upload geometries imported from a CAD environment. Based on such a representation, ArchNURBS performs the elastic isogeometric finite element analysis and the collapse limit analysis of the structure. It is possible to include in the analysis the presence of Fiber-Reinforced Polymers (FRP) extrados and intrados strips. A comprehensive descritpion of ArchNURBS is given in "ArchNURBS: NURBS-Based Tool for the Structural Safety Assessment of Masonry Arches in MATLAB", A. Chiozzi, M. Malagu', A. Tralli and A.Cazzani, J. Comput. Civil Eng., 2015. (http://ascelibrary.org/doi/abs/10.1061/%28ASCE%29CP.1943-5487.0000481) ArchNURBS has been developed thanks to a collaboration between the University of Ferrara (Italy) and the University of Cagliar

CASUP is a Cellular Automata (CA) library for HPC and supercomputers. It can be used in materials science (microstructure evolution, grain coarsening, fracture etc.), physics (Ising magnetisation) and for many other CA. If you use the library, please reference it as: A. Shterenlikht, L. Margetts, Three-dimensional cellular automata modelling of cleavage propagation across crystal boundaries in polycrystalline microstructures, Proc. Roy. Soc. A 471:20150039, DOI: http://dx.doi.org/10.1098/rspa.2015.0039. CASUP can be linked with FE (e.g. MPI FE library ParaFEM, http://parafem.org.uk) for a multi-scale multi-physics CA-FE framework. CASUP extensively uses Fortran 2008 and 2018 coarrays, as well as MPI, OpenMP and do concurrent. CASUP can be used with Cray, Intel and GCC/OpenCoarrays compilers. Scaling beyond 100,000 cores on Cray XC30 was demonstrated.
