The Package for Fitting Experimental Data of the YuMO Spectrometer by Theoretical Form Factors. Version 1.0. Long Write-Up and User's Guide
http://lt-jds.jinr.ru/record/7444
FITTER is a C++ code aimed to fit a chosen theoretical multi-parameter function through a set of data points. The method of fitting is chi-square minimization. Moreover, the robust fitting method can be applied. FITTER was disigned for a small-angle neutron scattering data analysis, using respective theoretical models. Commonly used models (Gaussian and polynomials) are also implemented for wider applicability.

SAS. The Package for Small-Angle Neutron Scattering Data Treatment. Version 2.4. Long Write-Up and User's Guide
http://lt-jds.jinr.ru/record/7401
The SAS program is aimed to process the spectra measured on the YuMO spectrometer (channel four of the IBR-2 reactor). The program allows one to combine data referring to the same sample, to calculate the spectrometer resolution function for the given experiment conditions, to carry out data correction on dead times of neutron detectors, and to subtract a background substrate from detector data (in two possible modes: using the neutron beam breaker or without it), to carry out the normalization of the obtained spectrum on the standard vanadium scatterer, to subtract background sample data.

Methods for Event Reconstruction in the CBM Experiment
http://lt-jds.jinr.ru/record/7118
Methods and algorithms for event reconstruction in the CBM experiment are described. All these results have been developed and presented by the LIT team at the CBM collaboration meetings in 2004-2005.

Program LATTICE for Calculation of Parameters of Targets with Heterogeneous (Lattice) Structure
http://lt-jds.jinr.ru/record/7009
Program LATTICE, with which help it is possible to describe lattice structure for the program complex CASCAD, is created in the C++ language. It is shown that for model-based electronuclear system on a basis of molten salt reactor with graphite moderator at transition from homogeneous structure to heterogeneous at preservation of a chemical compound there is a growth of k_{eff} by approximately 6 %.

http://lt-jds.jinr.ru/record/6797
Angular distributions of secondary particles produced in the interactions of sulphur and oxygen nuclei with photoemulsion nuclei at the energies of 200 and 60 GeV/nucleon are analyzed. With help of the wavelet analysis it is observed that the pseudorapidity distributions of the particles summered on all the events have three substructures. The distributions in separate events have more than one substructures in 40 % of the cases. The substructures are associated with the particles production in the target nuclei fragmentation region, in the central region, and in the projectile nuclei fragmentation region. The wavelet analysis allows one to separate events with different substructures.Uzhinskii, V VFri, 01 Oct 2010 12:47:47 GMThttp://lt-jds.jinr.ru/record/67972001WASP (Wavelet Analysis of Secondary Particles Angular Distributions) Package. Version 1.2. Long Write Up and User's Guide
http://lt-jds.jinr.ru/record/6734
WASP package is a C++ program aimed to analyze angular distributions of secondary particles generated in nuclear interactions. WASP package is based on wavelet transform algorithms. This work includes the user's guide, description of algorithms and mathematical methods, graphical user interface. We have also analyzed what problems of nuclear physics can be tackled with WASP.Altaisky, M VFri, 01 Oct 2010 12:47:45 GMThttp://lt-jds.jinr.ru/record/67342001
Application of TwoParameter Extrapolation for Solution of BoundaryValue Problem on SemiAxis
http://lt-jds.jinr.ru/record/6588
A method for refining approximate eigenvalues and eigenfunctions for a boundaryvalue problem on a halfaxis is suggested. To solve the problem numerically, one has to solve a problem on a finite segment [0,R] instead of the original problem on the interval [0,\infty). This replacement leads to eigenvalues' and eigenfunctions' errors. To choose R beforehand for obtaining their required accuracy is often impossible. Thus, one has to resolve the problem on [0,R] with larger R. If there are two eigenvalues or two eigenfunctions that correspond to different segments, the suggested method allows one to improve the accuracy of the eigenvalue and the eigenfunction for the original problem by means of extrapolation along the segment. This approach is similar to Richardson's method. Moreover, a twoparameter extrapolation is described. It is combination of the extrapolation along the segment and Richardson's extrapolation along a discretization step.
