**SGP-dec**- Scaled Gradient Projection technique for image deconvolution v. 1.0 (2011)

by R. Cavicchioli, R. Zanella, G. Zanghirati, L. Zanni

Available at www.unife.it/prisma/software

**Description.**A Matlab package for the deconvolution of 2D and 3D images corrupted by Poisson noise. Following a maximum likelihood approach, SGP-dec computes a deconvolved image by early stopping the scaled gradient projection (SGP) algorithm for the solution of the optimization problem coming from the minimization of the generalized Kullback-Leibler divergence between the blurred image and the observed image.

This code is developed with the support of the PRIN2008 Italian national research project "PRISMA - Optimization Methods and Software for Inverse Problems", grant n. 2008T5KA4L.

**PGPDT**-*Parallel Gradient-Projection-based Decomposition Technique*

by T. Serafini, L. Zanni, G. Zanghirati

Available at dm.unife.it/gpdt

**Description.**PGPDT is the parallel version of the C++ software GPDT. This version is designed for distributed memory multiprocessor architectures and it shares with the scalar version the same problem decomposition and gradient-projection methods.

**GPDT**-*Gradient-Projection-based Decomposition Technique*

by T. Serafini, L. Zanni, G. Zanghirati

Available at dm.unife.it/gpdt

**Description.**GPDT is a C++ software designed to train large-scale Support Vector Machines (SVMs) for binary classification on scalar environments. It uses a popular problem decomposition technique to split the SVM quadratic programming (QP) problem into a sequence of smaller QP subproblems, each one being solved by a suitable gradient-projection method (GPM). The currently implemented GPMs are the Generalized Variable Projection Method (GVPM) and the Dai-Fletcher method (DFGPM).

The software is available also in the Machine Learning repository mloss.org and it has been selected for inclusion in other widely used software packages such as the Matlab toolbox SHOGUN.

**ParLEA**- Parallel Likelihood-based Estimation of Admixture. Version 0.2 (2008)

by A. Giovannini, G. Zanghirati, M. Beaumont, L. Chikki, G. Barbujani

Available at dm.unife.it/parlea

**Description.**Estimating genetic population admixture is a difficult task that is shown to have meaningful applications in evolutionary and conservation Biology. Unfortunately state-of-the-art probabilistic approaches are computationally demanding. The ability of effectively exploiting the computational power of modern multiprocessor systems can thus contribute a beneficial impact to Monte-Carlo-based simulation of admixture modeling. Parallel LEA is a novel parallel approach for Likelihood-based Estimation of Admixture in population genetics, MPI and C++ based.

**JEpidemicS**- a Java tool for epidemic spread simulation through distance-dependent probabilities. Version 0.9beta (2010)

by E. Ganzaroli, A. Corli, G. Zanghirati.

**Description.**The software package is designed mainly for the simulation of the African Suine Fever (ASF) epidemic spreading in wide geographical areas and medium-to-long distances. It uses a graph-based multilayer structure and follows the object-oriented programming (OOP) paradigm, to allow for maximum flexibility, extendibility, easy of maintenance and connectivity to other available tools. The software is implemented in the Java programming language to ensure for maximum portability on a number of different hardware/software platforms, without the need for any source code adaptation. The whole project is developed by using only open-source libraries and public-domain databases of Earth maps. It allows the user to manually set the data or to load field data from external files. The simulations are based on a deeply studied model and allow the user to save the results in external files for statistical purposes. The package is different from other available simulation tools in the underlying model and in the features provided.

This software is part of a joint project of the underlying study and the developed code have been carried on in strict cooperation with Dr. V. Guberti. The project was a joint effort of the "Mathematics for Technology" Center of the University of Ferrara and the Food and Agricolture Organization (FAO) of the United Nations (UN).

**EpidemicS**- Epidemic Simulator. Version 1.0 (2009).

by E. Ganzaroli, A. Corli, G. Zanghirati.

**Description.**This is a MATLAB code based on cellular automata for the simulation of the disease spreading in wild animals, such as the suine fever in wild boars. The project has been developed in strict cooperation with Dr. V. Guberti and Dr. M. Fenati and was a joint effort of the "Mathematics for Technology" Center of the University of Ferrara and of the Italian National Institute for Wild Animals (INFS-CNR).

**ParTHERCONF**- Parallel THERmal CONFinement. Version 0.8 (2008)

by M. Bottoni, S. Mantovani, G. Berdondini, G. Zanghirati.

**Description.**Parallel code that describes the displacement due to thermophoresis of tiny particles in a gas-filled domain subjected to a temperature gradient. The behavior of the gas molecules and their interaction with material surfaces and with the particles floating in the gas are modeled with the statistical methods of molecular dynamics, based on the "Direct Simulation Monte Carlo" (DSMC). In case of polyatomic molecules sharing of the energy between translational and rotational modes is simulated with the Larsen-Borgnakke model. Interaction of polyatomic molecules with material surfaces is computed on the basis of the Cercignani-Lampis-Lord model. The computational code has extensive post-processing capabilities for visualization of computational results.

The software is coded in Fortran 77 with MPI communication routines. The serial version is called THERCONF-2D. The code*is not*available for distribution: please contact Dr. Eng. Maurizio Bottoni for additional information.

**MRItool**- A Matlab tool for functional Magnetic Resonance Image reconstruction. Version 1.0 (2000)

by E. Loli Piccolomini, M. Romagnoli, F. Zama, G. Zanghirati, A.R. Formiconi, S. Martini

Available at dm.unife.it/mritool

**Description.**This package performs the reconstruction of sequences of Functional Magnetic Resonance images with the Generalized Series approach. It has been developed in the context of the Italian MURST project "Numerical Analysis: Methods and Mathematical Software".

**PALMA**- Parallel Assets and Liabilities MAnagement

by G. Zanghirati and Prometeia Calcolo s.r.l. (1998)

**Description.**This is a C++ parallel software developed jointly with SMART s.r.l. and Prometeia Calcolo s.r.l. as a EU Esprit project in the High-Performance Computing and Networking (HPCN) action. The package is aimed to simulate and analyze the assets and liabilities dynamics for a financial firm or a bank, considering a variety of possible parameter setting and a large number of independent temporal scenarios.
