title: Sepulchral plate of Thomas Tympfius in St. Mary's Church in Gdańsk

description: The data set concerns epigraphy. It refers to the sepulchral plate placed in St. Mary’s Church in Gdańsk which is dedicated to Thomas Tympfius,  a minter who, together with his brother Andrew, rented several mints in the Kingdom of Poland, and gave his name to the timpf - the silver zloty released by the Tympfius mint. Unfortunately, as a result of economic difficulties caused by the Swedish Deluge, the coin was undervalued. In the end, these abuses forced Tomasz to flee from the Polish Kingdom and settle in Gdańsk, where he opened a department store. The data set contains one general photo of the sepulchral plate, transcription of its text in Latin, its Polish translation, and the short biography of the deceased, also in Polish.

title: Voltage fluctuations on the main switchgear of the industrial power system supplying the rolling mill motors

description: The dataset presents the voltage waveforms on the bus bars of the main switchgear of the industrial power network for the supply of rolling mills. The data was recorded during an experiment whose purpose was to determine a level of short-term and long-term flicker caused by voltage fluctuations. In the virtual application of flickermeter, a hardware (acquisition of measuring data) and a software (computer data processing and graphical interface ) part can be distinguished. The attached dataset contains raw data at the output of the hardware part of the flickermeter.
The measurements were carried out in one of the Polish steel mills, in the GST- 6 switching station, on medium voltage (6 kV) switchgear rails in measurement field 2a using voltage transformers. The voltage value on the secondary side of the transformers was 100/root(3) V (a phase voltage). Field 3a of the switchboard supplies the rolling mill motor, whose operation causes voltage fluctuations. The scheme of the switchgear with the measuring point marked is shown in Figure 1. The measurement lasted five hours from 11:10 to 16:10. After the initial rolling period (until 11:30), there was a break in the rolling mill operation until about 14:20.
Measurements were performed using a measurement system that allows simultaneous measurement of three phase-to-phase or two-phase voltages. In the hardware part of the measuring system (Figure 2), the signal is first pre-conditioned. The analog signal processing consists of matching the level of the measured signal to the inputs of the optoisolation amplifier, which ensures the separation of the high voltage signal. Then low-pass filtration through a set of anti-aliasing filters is carried out. The formation of the output digital signal from the analog signal takes place in the A/D converter with a 16-bit resolution and a sampling rate of up to 20 kS/s.
The sampling frequency is equal to 20 000 Hz and is inserted in the first row of the attached files.  Figure 1. The scheme of the switchgear with the measuring point marked  Figure 2. The hardware part of the measurement system

title: Herbarium of Division of Marine Biology and Ecology University of Gdańsk (DMBE)

description: Herbarium of Division of Marine Biology and Ecology University of Gdańsk (DMBE) is a research herbarium encompassing specimens of vascular plants and algae hosted by the Laboratory of Marine Plant Ecology at University of Gdańsk, Poland. The aim of Herbarium is to preserve marine plant and algae collections mostly from the Gulf of Gdańsk, but the herbarium also holds specimens from other parts of the world.
Our overall goal is to understand plant diversity and to provide practical solutions assisting with its analysis and documentation. Gathered specimens provide direct evidence of biodiversity in time and space, the evidence for plant distributions, conservation and threat, the raw material for field and identification guides, the comparative data for discovering species and writing taxonomic papers and an educational resource for learning.
Our collection of preserved plant specimens, used for scientific study and plant identification and classification, involved two activities—gathering the specimens and recording the information. Specimens in good condition were chosen and collected directly from the environment; snorkeling or scuba-diving method were also implemented. After the collection of each specimen, a unique collection number was assigned. Most specimens in the herbarium are pressed, dried plants. These pressed specimens are mounted on sheets of card and stored in flat folders.
File ‘Herbarium_of_Division_of_Marine_Biology_and_Ecology’ follow the Darwin Core Archive (DwCA) specifications for the field, holding one record per specimen with all core specimen fields (herbarium info, current identification, collector info, dates, location, notes, etc.). Each occurrence record is uniquely identified within the DMBE Herbarium database by a field called id (DwCA).
To conclude, the DMBE herbarium is particularly rich in the genera Chara and individuals under protection, which makes this collection an extensive reference collection of Gulf of Gdańsk macrophytes.

title: Electronic transition dipole moment functions of the first singlet Pi gerade and first triplet Pi gerade states of the Lithium dimer

description: Electronic transition dipole moment functions (ETDMF) of the first singlet Pi gerade (1sPg) and first triplet Pi gerade (1tPg) states 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 four 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 five 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 four 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: Simulation of signal acquisition from a rotary flowmeter

description: The dataset contains results of simulation measuring the flow of homogeneous substances by rotational flow meter: a moment of impulse at the output of flow meter, time between successive pulses, number of pulses counted from standard generator and relative error of measurement.
The main part of rotational flow meter is a rotor (vane or screw) rotating at a speed which is the function of the fluid or gas flow rate. A pulse signal with a frequency proportional to the speed of the rotor is obtained at the sensor output. For measurements in dynamic conditions, a variable interval between pulses prohibits the analysis of the measuring signal. The impulse at the output of the flow meter appears at time ti, where the time ti-ti-1 of the previous pulse ti-1 depends on the average flow rate at that time.
The result is a pulse signal w(t) of the distance between the pulse proportional to the average flow rate.  The pulse signal w(t) of frequency proportional to the flow rate of the fluid flow qv(t)

title: Areas of updraft air motion from WRF model simulations.

description: Presented dataset is a part of numerical modelling study focusing on the analysis of sea ice floes size distribution (FSD) influence on the horizontal and vertical structure of convection in the atmosphere. The total area and spatial arrangement of the updrafts indicates that the FSD affects the total moisture content and the values of area averaged turbulent fluxes in the model domain. In fact, while convective updrafts occur in every one of model simulations, their intensity differs with varying FSD due to the changing extent and strength of breeze-like circulation. When the floes are tightly packed in the model domain (simulations with 1000 and 5000 floes) the updrafts are numerous but weaker due to weaker breeze like circulation. In the simulations with smaller floes numbers (Nf =50 and Nf=100) the opposite situation takes place and the updrafts, while covering smaller area, are stronger and thus are the values of total moisture and area averaged heat content for the model domain, as described in Wenta and Herman (2019).
Presented dataset consists of:
Description of WRF model configuration and the model output post processing (Techinical_details.docx).

title: Very low resolution depth images of 200,000 poses

description: A dataset represents simulated images of depth sensor seeing a single human pose, performing 200,000 random gestures. The depth images as vectors of pixels are stored with ground truth positions of every relevant joint.
3D graphics software (Blender 3D) was used to model, pose and render human figure, creating depth image and appropriate ground truth for each pose. It was assumed, that the sensor has a horizontal field of view 57° (same as Kinect), and the depth image was rendered to 60×50 pixels in 8-bit greyscale (3-bit less, i.e. 8 times lower depth resolution than Kinect).
The human figure was positioned in an empty space, without a background and other foreground objects. In real applications to obtain the same conditions a separation of foreground object based on depth information should be performed, e.g. by assuming the body to be the object closest to a camera, and discarding the ones positioned further by comparing their depth values.
The dataset represents a wide variation of the upper body poses with biologically correct random joints positions, with wrists positions uniformly covering the available space in front of the figure. The body absolute position was changed randomly to introduce shifts in x, y and z directions relative to the fixed sensor. The movement ranges were limited to allow only far reaching hands to leave the frame, whilst the rest of the figure remained visible. 200,000 depth images were created.
The applications of the database include training of object detection and tracking algorithm for body pose recognition.
