IAC-DIDAS-L Dynamic Interactive Decision Analysis and Support System Linear Version
This paper is one of the series of 11 Working Papers presenting the software for interactive decision support and software tools for developing decision support systems. These products constitute the outcome of the contracted study agreement between the System and Decision Sciences Program at IIASA and several Polish scientific institutions. The theoretical part of these results is presented in the IIASA Working Paper WP-88-071 entitled "Theory, Software and Testing Examples in Decision Support Systems". This volume contains the theoretical and methodological backgrounds of the software systems developed within the project.
This paper presents user documentation for two versions of decision analysis and support systems of DIDAS family: IAC-DIDAS-L1 (pilot version) and IAC-DIDAS-L2. These programs can be used for supporting decision problems when the model of the decision situation can be described using the linear programming framework
Classification of Low Dimensional Lie Super-Bialgebras
A thorough analysis of Lie super-bialgebra structures on Lie super-algebras
osp(1|2) and super-e(2) is presented. Combined technique of computer algebraic
computations and a subsequent identification of equivalent structures is
applied. In all the cases Poisson-Lie brackets on supergroups are found.
Possibility of quantizing them in order to obtain quantum groups is discussed.
It turns out to be straightforward for all but one structures for super-E(2)
group.Comment: 15 pages, LaTe
Wroclaw neutrino event generator
A neutrino event generator developed by the Wroclaw Neutrino Group is
described. The physical models included in the generator are discussed and
illustrated with the results of simulations. The considered processes are
quasi-elastic scattering and pion production modelled by combining the
resonance excitation and deep inelastic scattering.Comment: Talk given at 2nd Scandanavian Neutrino Workshop (SNOW 2006),

axial form factor from bubble chamber experiments
A careful reanalysis of both Argonne National Laboratory and Brookhaven
National Laboratory data for weak single pion production is done. We consider
deuteron nuclear effects and normalization (flux) uncertainties in both
experiments. We demonstrate that these two sets of data are in good agreement.
For the dipole parametrization of , we obtain , GeV. As an application we present the discussion of
the uncertainty of the neutral current 1 production cross section,
important for the T2K neutrino oscillation experiment.Comment: 16 pages, 8 figures, 2 table
