The fuel cell were heated up to 750 °C (3 °C min-1) for reduction and then cooled down to 700 °C for the main test after 24 h stabilisation. Fuel cell tests were conducted with the total flow rates of 100 ml min-1 and 200 ml min-1 on anode (50% steam / 50% H2) and cathode side, respectively. Solartron 1260/1287 frequency analyser was used for EIS measurement.

title: Calculations of the resistance values of 20 thermistors at 50°C

description: The presented data set is part of the research aimed at determining the actual characteristics of each thermistor in a package of twenty NTC10k type sensors.
The measurement system is shown in Fig. 1. A measurement system based on NI PXIe-1082Q (National Instruments Chassis), equipped with NI PXIe-8135 (Embedded Controller), NI PXIe-6341 (DAQ card) and NI SCB-68A (68-pin connector block), was used for the acquisition of measurement data. Eleven input channels of the DAQ card were used in the measurements. Channel 0 (ch_0) was used to measure the supply voltage. Sensors numbered 1 to 20 were tested in two parts, ten sensors per set. They were connected to the inputs of channels 1-10 (ch_1-ch_10) of the DAQ card.
The conditioning unit for individual sensors is shown in Fig.2. These circuits are performed on connector block SCB-68A as the voltage dividers. For the set of ten thermistors, the supply voltage is measured in channel 0 (ch_0) of the DAQ card, and individual thermistors are connected to channels 1-10 (ch_i).
The thermistor set was placed in a thermal tank containing a mixture of water and ice at a temperature of 100°C (confirmed by a digital temperature gauge DT-34 with an accuracy of 0.1°C).
The calculations of the resistance values were performed based on the datasets [Maśnicki, R., Tyndzik, K., & Pałczyńska, B. (2021). Calibration of NTC 10k thermistors in temperature of 100 C [Data set]. Gdańsk University of Technology. https://doi.org/10.34808/hexp-sy19].  Fig. 1. The measurement setup Datasets consist of 15 files 50,0Cx.lvm, and II50,0Cx.lvm (where: x is from 0 to 14), containing the measurement results supply voltages Uz (ch_0) (Fig. 2) and voltages at the outputs of ten voltage dividers (ch_1 to ch_10), repeated in two series (at 100.0°C, for two batches of thermistors, 10 per batch) with 30 measurements for each of the 11 channels. The resistance calculations were performed for 20 thermistors. The file Rt50.0C.lvm contains data for the first part (ten thermistors), and file RtII50.0C.lvm contains data for the second part (another ten thermistors) of 20 thermistors set.                                                                                                                Fig. 2.

title: Video of LEGO bricks on conveyor belt - Wide Brics

description: 



The set contains videos of LEGO bricks (wide bricks, with each side having more than 1 stud) moving on a white conveyor belt. The videos were prepared for training neural network for recognition of LEGO bricks. The bricks were separated as much as possible and in most cases they should not overlap. The images were taken from different sides by stationary camera located over the final conveyor belt.
 
The videos were recorded using Huawei p20 Pro camera (1920x1080 resolution, H.264 high profile codec, 15 frames per second) located 14.5 cm over the belt. The bricks have random colors. The videos were placed in a seperate file for different pin type.
 
Sample images are presented below.

title: Tagged images with bees 3

description: 





Images taken from bee hive with tagged bees. The images are random frames from movies recorded in may 2017 and 2018. All images are taken from full HD video stream.
The images filenames are  the same as filename of source video, so it should be easy to match. Labels inside each file follow a name convention:e.g. rawdata/DSCN9958_segment_007_frame_210_scale_0_8.bmp means that:* video filename is DSCN9958* segment number is 7 (it's 8th frame chosen from this video, numbers start from 0)* frame number is 210 (it's 211th frame of all frames in this video, numbers start from 0)* scale of tagged video is 0.8 ("_" instead of "."), to use labels for full scale videos, you need to unscale the labels
The tagging of the images was done manually using objectmaker.exe tool (supplied with the part 1 of the data, see references). The tags are stored in text files with names identical as the movie filename and has the following format: "image_name number_of_tags x_coordinate_of_top_lef_corner y_coordinate_of_top_lef_corner x_coordinate_of_bottom_right_corner y_coordinate_of_bottom_right_corner". The coordinate set is provided number_of_tags times.

title: EIS measurements for the LSC layer as a function of annealing temperature

description: Electrochemical impedance spectroscopy (EIS) was employed to evaluate the ohmic resistance (Rₒₕₘ) and polarization resistance (Rₚₒₗ) of the fabricated symmetrical cells (LSC|CGO|LSC). Measurements were conducted using a sinusoidal excitation signal with an amplitude of 25 mV over a frequency range spanning from 3 MHz to 50 mHz. The specimens were mounted in a compression setup, where each side of the sample was in contact with a gold mesh, which was electrically connected to platinum wires extending outside the furnace chamber. The primary objective of the EIS analysis was to investigate how the structural characteristics of the material—specifically, its partially amorphous and crystalline nature—affect its catalytic performance. All measurements were carried out under a synthetic air atmosphere at a controlled flow rate of 50 ml·min⁻¹. The temperature range for the experiments was adjusted according to the specific annealing temperature of each sample. For samples annealed at lower temperatures, measurements were taken at smaller temperature intervals to enable a more detailed assessment of the material's behavior in the low-temperature regime.

title: Uniform expansion estimates in the quadratic map as a function of the partition size, using the “derivative” partition type

description: This dataset contains selected results of numerical computations described in the paper "Quantitative hyperbolicity estimates in one-dimensional dynamics" by S. Day, H. Kokubu, S. Luzzatto, K. Mischaikow, H. Oka, P. Pilarczyk, published in Nonlinearity, Vol. 21, No. 9 (2008), 1967-1987, doi: 10.1088/0951-7715/21/9/002.
Using an approach based on graph algorithms described in the paper, comprehensive computation was conducted to obtain a rigorous lower bound on the expansion exponent λ (Statement 1 in the paper), the constant C (Statement 1 in the paper), and the adjusted exponent λ0 (Statement 2 in the paper). The size of the partition into which the domain of the map was subdivided is denoted by K. The radius of the critical neighborhood is denoted by δ. The key parameter of the map is denoted by a. The parallelization framework introduced in the paper "Parallelization method for a continuous property" by P. Pilarczyk, as published in Foundations of Computational Mathematics, Vol. 10, No. 1 (2010), 93–114, doi: 10.1007/s10208-009-9050-8, was used in order to use several CPUs at a time. Note that the data records are not sorted.
In this specific computation, the quadratic map was analyzed with a=2, δ=0.01, and K∈[100,7900]. The partition type called “derivative” was used.
The data is provided in plain text format. Each line with comments begins with a semicolon, each line with a single data record begins with an asterisk. Each data record consists of the following items, separated with the space:
the asterisk that indicates the beginning of a data record
the identifier of the data record in the format level:number (e.g., 4:12)
the left endpoint of the parameter interval (minimal parameter value)
the right endpoint of the parameter interval (maximal parameter value)
the total number of intervals that cover both the critical neighborhood and the remainder of the domain of the map
the diameter δ of the critical neighborhood
the computed expansion exponent λ
the computed value of log C (0 if not computed)
the computed value of λ0 (0 if not computed)
the computation time (in seconds)
