title: Adiabatic potential energy curves of the singlet Pi and Delta gerade states of the Lithium dimer

description: Adiabatic potential energy curves of the singlet Pi and Delta gerade states have been calculated for the Lithium dimer. The results of the three excited states of the symmetries singlet 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 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. 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 four columns. The first column contains distances in Bohr radius units [a0] between Lithium atoms. The consecutive three columns contain potential energies of interaction between Li atoms calculated for corresponding distances. Energies are shown in inverse centimeters units [cm-1]. All curves are tabulated according to internuclear distance from 3.2 [a0] to 88 [a0].

title: The time-varying low-frequency magnetic-field emitted from the ship’s inverter-fed induction motor

description: The dataset contains the magnetic field measurement results that are part of a comprehensive study on the assessment of the magnetic field emissions onboard of the research-training vessel. The measurements were carried out, nearby the bow thruster motor fed from the inverter, during maneuvering and the sea voyage. The bow thruster is assembled in the forepart of the ships’ hull and has constant pitch propeller. Using the control levers at the wings of the bridge, it is possible to change the speed and direction of the revolutions of the propeller, and in this way to move the bow of the ship during maneuvering. The bow thruster is driven with a squirrel cage asynchronous motor fed by the PWM frequency converter. The IGBT (Isolated Gate Bipolar Transistor) inverter was operating at 2 kHz (possible 4 kHz) switching frequency. The inverter output frequency was adjusted in the frequency range from 0 to 50 Hz. Measurements were performed in the bow thruster compartment with the ESM-100 H/E field meter, which was fixed on the wooden bar, about 1 m from the bow thruster motor (Figure 1).  
Data recording of magnetic field emissions was carried out with a/d converters of the data acquisition board (DAQ), which were connected to the analog outputs of an isotropic field meter (Figure 2). ESM-100 H/E field meter, which was applied in this system, enables the measurements of a magnetic field induction in the measuring ranges from 1 nT to 20 mT. Four wide-band analog outputs of this meter afford possibilities for measuring the time waveforms of the magnetic fields, separately in the three orthogonal directions, in the output voltage range from 0 to 600 mV (see Table). The measured analog signal is conditioned with the use of National Instruments sub-assemblies. The initial conditioning follows and is realized through the low-pass filter module (for antialiasing application) with programmable cut-off frequency. The applied module has 8th-order elliptic filters, which provide a very sharp roll-off. Matching of the signal level to the a/d converter the DAQ input is realized by the input amplifier with the programmable gain. The formation of the output digital signal from the analog signal takes place in the a/d converter with a 16-bit resolution and sampling rate equal to 20 kS/s. Discrete signals are next analyzed (off-line) with the use of virtual instruments (LabVIEW software).  Figure 1. The ESM-100 H/E field meter located close to the bow thruster motor Figure 2.

title: The voltage on bus bars of the main switchboard of the ro-ro ship electrical power system during maneuvering

description: The dataset is part of the research results on the quality of supply voltage on bus bars of the main switchboard of the ship's electrical power system in different states of ship exploitation. The attached dataset contains the measurement results carried out onboard a ro-ro ship during maneuvering.
The ro-ro ship is equipped in three-phase, three-wire electrical power systems. The ship's electrical power plant consists of two free-standing generators 1000 kVA each and two-shaft generator 1500 kVA each (see Figure 1). The nominal voltage on bus bars of the main switchboard was 400 V with a frequency equal to 50 Hz. The voltage of 220V has been obtained by means of a transformer.  During the maneuvering and re-loading operations, the two free-standing generators G1 and G2 have been used.  The single shaft generator has been used during sea voyage as well as during maneuvering as an energy source of a bow thruster. The each of shaft generators could not work in parallel with other electrical energy sources, excluding short switching time (roughly 2 seconds). The shaft generators have been connected with the remaining system only with the help of a simple circuit breaker. It has been possible thanks to adjusting screw propellers using.
The voltage waveforms on bus bars of the main switchboard were recorder with the digital measuring system, which allows the simultaneous measurement of three phase-to-phase or two-phase voltages. The initial conditioning of the input signals is carried out by optoisolation amplifiers and a low-pass filter module (antialiasing). The formation of the output digital signal from the analog signal takes place in the a/d converter with a resolution of 16 bits and a sampling rate of up to 20 kS/s. Using three channels at the same time allows the maximum sampling rate of 6.6 kS/s. The block diagram of the digital measuring system is shown in Figure 2.
The files contain voltage waveforms of the output of a/d converters in [V], in three phases for 400 V and 220V networks. The attenuation and offset of the measuring path for the 220 V network are 77.6398 [V/V] and -0.017 V, respectively. For the 400 V network, the attenuation and offset of the measuring path are equal to 134.0123 [V / V] and -0.0175 V, respectively. The sampling frequency is inserted in the first row of the attached files.
The files are described as follows: ro-ro_maneuvering_the value of the mains voltage (400 or 220)_number of the set. The file named ro_ro_prepare_maneuvering_400.TXT contains measurement data that was recorded during preparation for maneuvering.  Figure 1.

title: Indicators describing the effectiveness of tax systems of selected OECD countries

description: The following research data include indicators describing the effectiveness of the tax administration activity in Poland compared to selected countries. In economic understanding efficiency is measured by the calculation of the expenditure of funds spent on its operation and performance of statutory functions. In this respect, the basic indicator is the efficiency of tax collection, measured by the proportion of their value to collection costs. The Polish tax system can be considered modeled on the solutions used in Western European countries. Moreover, many legal provisions were implemented directly as part of the harmonization processes after Poland joined the European Union. Therefore, by analyzing qualitative and quantitative indicators and comparing them with the results achieved by Western European countries, it is possible to assess the functioning of the tax collection apparatus in Poland.This research data includes information, inter alia,  (1) Annual number of hours devoted by Polish entrepreneurs to tax issues in the company,  (2) Average expenditure on tax administration in relation to GDP in selected OECD countries in 2005-2013, (3) Population per one tax administration employee in selected OECD countries.

title: Sea ice floe size and shape data from a very high resolution satellite image (Knox Coast, East Antarctica)

description: This dataset contains floe size distribution data from a very high resolution (pixel size: 0.3 m) optical satellite image of sea ice, acquired on 16. Feb. 2019 off the Knox Coast (East Antarctica). The image shows relatively small ice floes produced by wave-induced breakup of landfast ice between the Mill Island and Bowman Island. The ice floes are characterized by a narrow size distribution and angular, polygonal shapes, typical for sea ice broken by waves.
The original image is divided into three sectors, labelled A, B and C, with different `populations' of ice floes in terms of their mean size and shape properties.
The content of the dataset, for each sector:
boundaries and position of each floe identified within that sector,
geometric properties of each floe (surface area, minimum and maximum caliper diameter, rectangularity, minor and major axis of a fitted ellipse, etc.),
an image illustrating the identified floes and their width.
The data in points 1. and 2. above are available as Matlab .mat files, the detailed content of which is described in the readme.txt file, included in the main dataset folder.
The image processing and object identification methods used to extract the floe data from the original image, as well as the background weather, wave and sea ice data allowing the reconstruction of sea ice-wave interactions that produced the observed sizes and shaped of ice floes, can be found in the following paper:
