title: Potential energy curves of the doublet Pi and Delta gerade states of the Lithium dimer cation

description: Adiabatic potential energy curves of the doublet Pi and Delta gerade (dPg and dDg) states have been calculated for the Lithium dimer cation (Li2+). The results of the four excited states of the symmetries doublet Pi and Delta gerade have been obtained by the nonrelativistic multireference configuration interaction (MRCI) method used with pseudopotentials describing the interaction of valence electrons with atomic cores. In this approach, only the valence electron of the one Li atom was treated explicitly. The core polarization potential has been also applied in calculations. All computations were performed by means of the MOLPRO program package. Presented potentials are ready to compare with the results of other theoretical results and potential energy curves derived from experiments.
The dataset is arranged in five columns. The first column contains distances in Bohr radius units [a0] between Lithium atom and Lithium ion. The consecutive four columns contain potential energies of interaction between Li and Li+ calculated for corresponding distances. Energies are shown in inverse centimeters units [cm-1]. All curves are tabulated according to internuclear distance from 2 [a0] to 100 [a0].

title: Electronic transition dipole moment functions of the first triplet Sigma ungerade plus state of the Lithium dimer

description: Electronic transition dipole moment functions (ETDMF) of the first triplet Sigma ungerade plus (1tSu+) state have been calculated for the Lithium dimer. ETDMFs are needed in understanding processes like photodissociation, photoassociation, cooling, and trapping of molecules. The results of the five ETDMFs have been obtained by the nonrelativistic multireference configuration interaction (MRCI) method used with pseudopotentials describing the interaction of valence electrons with atomic cores. In this approach, only the valence electrons of the Li atom were treated explicitly. The core polarization potential has been also applied in calculations. All computations were performed by means of the MOLPRO program package. In all internuclear regions, presented ETDMFs reasonably agree with available previously calculated and measured results.
The dataset is arranged in six columns. &lt;Ψ_f | DMX or DMY or DMZ | Ψ_i&gt; is the x or y or z component of the electronic dipole moment between the initial state Ψ_i and the final state Ψ_f of the diatomic Lithium molecule. The first column contains distances in Bohr radius units [a0] between Lithium atoms. The consecutive five columns contain ETDMFs calculated for corresponding distances. All values are given in atomic units. All ETDMFs are provided as functions of the internuclear distance R, ranging from 2 to 90 [a0].
The symbols used for describing the initial (Ψ_i) and final (Ψ_f) states (for example 2tPg or 4sSu+) of the Li2 molecule are the following:
1 or 2 or ... - the electronic initial or final state number;
s or t - singlet or triplet state;
S or P or D - Sigma, Pi or Delta state;
g or u - gerade or ungerade state;
+ is connected only with Sigma states.

title: Minimal number of periodic points with the periods less or equal to r in the smooth homotopy class of simply-connected manifolds of dimension 8 and homology groups with the sum of ranks less or equal to 10

description: An important problem in periodic point theory is minimization of the number of periodic points with periods &lt;= r in a given class of self-maps of a space. A closed smooth and simply-connected manifolds of dimension 8 and its self-maps f  with periodic sequence of Lefschetz numbers are considered. The topological invariant Jr[f] is equal to the minimal number of periodic points with the periods less or equal to r in the smooth homotopy class of f. For sufficiently large r the invariant Jr[f] is independent of the choice of r and in that case it is natural to write J[f] instead of Jr[f]. We provide the values of the simplified version of the invariant: J[f] (mod 2) (which is equal either J[f] or J[f]+1) for  manifolds of dimension 8 having the sum of ranks of homology groups less or equal 10. The results are based on the combinatorial scheme for computing J[f] introduced in “Minimization of the number of periodic points for smooth self-maps of simply-connected manifolds with periodic sequence of Lefschetz numbers” by G. Graff and A. Kaczkowska, [Cent. Eur. J. Math., 10(6), 2012, 2160-2172, https://doi.org/10.2478/s11533-012-0122-7]. The data contains text files of the form J[vector_of_ranks _of_homology_groups].txt. Each file consists of all possible triples, structured as follows: the first position contains a sequence of lists, where the i-th list corresponds to the degrees of non-zero eigenvalues of the i-th induced homomorphism, the second position contains a set of non-zero periodic expansion coefficients, the third position contains corresponding value of the invariant J[f].

title: The database of odd algebraic periods for quasi-unipotent self-maps of a space having the same homology group as the connected sum of g tori

description:  
 Algebraic periods defined in terms of Lefschetz numbers of iterations are an important tool for studying periodic points. A map is called quasi-unipotent if all eigenvalues of the induced maps on the homology groups with rational coefficients are roots of unity. 
 

The dataset consists of 20 files indexed by numbers g=1,...,20. Each file provides sets of odd algebraic periods for all quasi-unipotent self-maps of a space having the same homology groups as the connected sum of g tori. Let us remark that each data set covers all algebraical restrictions that come from zeta functions for the sets of  minimal  Lefschetz periods of Morse–Smale diffeomorphisms of M(g) being the connected sum of g tori.
The results are based on the algorithm available in the paper: G. Graff, M. Lebiedź, A. Myszkowski, Periodic expansion in determining minimal sets of Lefschetz periods for Morse–Smale diffeomorphisms, J. Fixed Point Theory Appl. (2019) 21:47, https://doi.org/10.1007/s11784-019-0680-4.

title: Simulation of a linear pneumatic actuator with 100 mm piston diameter, 32 mm piston rod diameter and 100 mm stroke

description: The aim of the simulation was to determine the dynamics of linear pneumatic actuators with different sizes and flow properties. The simulation used the actuator dynamics model as described in [1] and the St Venant - Wantzel's mass flow rate model. The simulation experiment was to calculate the pressure changes in both chambers of the actuator as well as the position and velocity of the piston during the stroke. The simulation results were saved in the default GNU Octave (text) format. The original purpose of the experiments was to obtain data to create a neural model of a pneumatic actuator.[1] Kiczkowiak T.: Algorithms and Models Applied in the Design of Pneumatic Driving Systems (in Polish), Koszalin 2005, Publishing House of Koszalin University of Technology

title: Strucutral steel - tensile test results

description: Modern floating structures such as ships, oil platforms and offshore wind towers are built mostly of structural steel. It is a material that is subject to requirements which, when met, allows the construction and safe operation of the structure throughout its entire work cycle. One of the basic criteria that a material must meet is its strength. The most common basic description is a set of parameters such as yield point (proof strength), ultimate strength, elongation at break, section reduction. These parameters are determined in a standardized test - static tensile test. This is a destructive test, the material taken for testing is destroyed and can no longer be used.
Dataset is dedicated mainly to students, for their own analysis of material behavior during a static tensile test. It can also be used to calibrate numerical models. Dataset contains a record of five tensile tests of St3s steel, which is equivalent to normal strength hull steel grade A. The tests were carried out in accordance to PN-EN ISO 6892:2016-09 standard, record of displacement from the traverse of the testing machine. Raw data.

title: Number of selected entities (companies) of the national economy in 2008 - 2017

description: Currently, most enterprises in Poland are run as sole proprietorships. In addition, natural persons running a business may run an enterprise as part of civil partnerships, which are a relatively simple form of business operation by more than one person (at least two partners). In addition, there is a growing interest in establishing commercial law companies, especially in the field of limited liability companies (running a business within this type of companies allows to minimize the financial risk and material liability of partners, and under certain conditions to avoid the need to incur additional levies, for example in the field of mandatory social insurance, the so-called ZUS contributions). The following data contains the number of selected entities (companies) of the national economy in 2008 - 2017.
