title: Dataset of non-isomorphic graphs being coloring types (K6-e,Km-e;n), 2<m<5, 1<n<R(K6-e,Km-e)

description: For K6-e and Km-e graphs, the type coloring (K6-e,Km-e;n) is such an edge coloring of the full Kn graph, which does not have the K6-e subgraph in the first color (no edge in the graph) or the Km-e subgraph in the second color (exists edge in the graph). Km-e means the full Km graph with one edge removed. The Ramsey number R(K6-e,Km-e) is the smallest natural number n such that for any edge coloring of the full Kn graph there is an isomorphic subgraph with K6-e in the first color (no edge in the graph) or isomorphic with Km-e in the second color (exists edge in the graph). Coloring types (K6-e,Km-e;n) exist for n&lt;R(K6-e,Km-e).
The dataset consists of:a) 7 files containing all non-isomorphic graphs that are coloring types (K6-e,K3-e;n) for 1&lt;n&lt;9,b) 15 files containing all non-isomorphic graphs that are coloring types (K6-e,K4-e;n) for 1&lt;n&lt;17.
All graphs have been saved in Graph6 format (https://users.cecs.anu.edu.au/~bdm/data/formats.html).The Nauty package by Brendan D. McKay was used to check the isomorphism of the graphs (http://users.cecs.anu.edu.au/~bdm/nauty/).
We recommend the survey article of S. Radziszowski containing the most important results regarding Ramsey numbers: S. Radziszowski, Small Ramsey numbers, Electron. J. Comb. Dyn. Surv. 1, revision #15, DS1: Mar 3, 2017 (https://doi.org/10.37236/21).

title: EH36 steel for shipbuilding - fracture documentation for CTOD test (plate thicnkness 30mm), a0/W = 0.5

description: The basic method of ductility designation of structural steels is the Charpy impact test. The test consists of a single strike of the specimen using a Charpy pendulum. Its result is the value of work necessary to break a specimen at a test temperature. Despite its many advantages, such as its short implementation time and low costs, it has its disadvantages, in particular:
• strong influence of notch geometry on the test result, which means that impact strength cannot be considered as an unambiguous material property,
• milled notches are not repeatable because the cutter wears,
• regardless of the thickness of the material being tested, samples of the same size are used.
Due to these disadvantages, for very responsible ship and ocean engineering constructions, such as: continuous longitudinal coamings of the largest container ships, or supporting components of drilling platforms, tests are carried out basing on fracture mechanics. For shipbuilding industry, CTOD (Crack Tip Opening Displacement) is, the most often, desired value. The test CTOD is performed by slowly bending the specimen with record of the slit opening. Before performing the test, it is necessary to know the material properties (from a tensile test). The final stage of the test is the measurement of the initial fatigue fracture geometry.
The dataset contains the photographic documentation of fracture and measurement of fatigue precrack for a0/W = 0.50 specimen.

title: Electrical properties of silicate-lead glasses containing nanostructures of iron oxides.

description: Electrical properties of silicate-lead glasses doped with different content of iron oxide was studied. The set of glass samples were prepared with the composition of (50 − 0.5x)SiO2–(50 − 0.5x)PbO–xFe2O3, where x = 2, 5, 10, 15, 20 and 25 (in mol%).  All sampleswere prepared by the conventional melt quenching technique; the melting was conducted in air at 1623 K in alumina crucibles. The melts were poured on a brass plate preheated to 573 K and formed into button-shaped samples. Afterwards pellets were annealed at 673K, cooledwith the furnace and polished to the thickness of about 1mm. For the electrical conductivity measurements, golden electrodes were evaporated at both sides of preheated samples in vacuum. The linear impedance spectra were measured in the frequency range of 1 MHz to 1 MHz and in the temperature range of 153 K to 423 K by Novocontrol Concept 40 broadband dielectric spectrometer.

title: Change of catalytic parameters for SOFC fueled by H2 and biogas mixture at 750 C

description: The dataset contains the Change of catalytic parameters for SOFC fueled by H2 and biogas mixture at 750 C (60:40 CH4:CO2). The outlet concentration of the gases from SOFC were measured using novel FTIR-based unit. The parameters are conversion rates, selectivities and yields of products
Measurement procedure:
"The concentration of gases determined from FTIR data allowed calculating other catalytic parameters: the conversion rates X of CH4 and CO2 the selectivities S of CO and H2 and the yields Y of CO and H2. X,S and Y are expressed in percentages. Conversion (X) gives us information about how much of an initial fuel was utilized in a fuel cell chamber (both within reforming and electrochemical processes). The yield (Y) parameter shows how much of the desired product (CO or H2) was found in the outlet stream with respect to the theoretical amount calculated from the chemical reactions, whereas selectivity (S) indicates how much of desired product was formed in ratio to the utilized fuel. All calculations have been done assuming that no leakage of inlet or exhaust gases was present." (10.1016/j.ijhydene.2019.03.243)

description: The MODALITY corpus is one of the multimodal database of word recordings in English. It consists of over 30 hours of multimodal recordings. The database contains high-resolution, high-framerate stereoscopic video streams and audio signals obtained from a microphone array and a laptop microphone. The corpus can be employed to develop an AVSR system, as every utterance was labelled. Recordings in noisy conditions can be used to test the robustness of speech recognition systems.
The language material was based on a remote control scenario and it includes 231 words -numbers, names of months and days, a set of verbs and nouns related to a computer device control. They were read by speakers as separated words and sequences resulting in a set of 12 recording sessions per speaker. Half of the sessions were recorded in quiet conditions, the other half contained three kinds of intrusive signals (traffic, babble and factory noise).
The corpus includes recordings of 42 speakers (33 male, 9 female). The participants include 20 students and staff of Multimedia Systems Department of the Gdańsk University of Technology, 5 students of the Institute of English and American Studies of the University of Gdańsk, and 17 native English speakers.

title: Students, graduates and lecturers at non-public universities in 1997-2011

description: At the beginning of the 2010/2011 academic year, there were 328 private universities educating 580.1 thousand students (i.e. 31.5% of all students). Compared to the previous year, there was a slight decrease in the number of non-public universities, moreover, the number of young people studying there decreased by 8.4%.
The very high dynamics of growth in the number of universities and students observed in the last decade of the 20th century and in the first five years of the 21st century has clearly weakened in recent years. While the number of universities in the 2010/2011 academic year increased by 48.4% compared to the 2000/2001 academic year, it slightly decreased compared to the previous year.
