title: The aggregation of objects representing Gdańsk district buildings - scale 1:25000

description: The process of automatic generalization is one of the elements of spatial data preparation for the purpose of creating digital cartographic studies. The presented data include a part of the process of generalization of building groups obtained from the national geodesy and cartography resource from BDOT10k (10k topographic database) [1].
The data include the spatial scope of Gdańsk district. In the city, there are buildings of each class according to the BDOT10k classification. Single-family residential buildings constitute 47% of all buildings, buildings with three or more apartments 18%, farm buildings 15%, each of the remaining classes contains less than 4%.
The provided data include original data downloaded from geoportal.gov.pl (on 6 November 2020) [2] as well as processed data. The aggregation process was performed taking into account the proximity of the neighborhood [3] based on the minimum size of the figure [4, 5]. The data are the basis for the subsequent steps in the process of sequential generalization of building groups.

title: Testing HIADAC high impedance analyzer in Trento University laboratory on protective foil using 2-wire probe 24h exposition

description: The dataset presents impedance spectrum of anticorrosion foil (coating) protecting aluminium frame . This object was used to test high-impedance analyzer for diagnostic of anticorossion coatings (HIADAC) realized in the frame of Eureka project E!3174.  The impedance spectrum frequency range (0.1 Hz – 100 kHz) was selected in order to test the whole measureement range of the analyzer. In this dataset, the DC polarisation was automatically set to compensate open-circuit potential and AC amplitude was set to 20 mV.  The model together with the 2-wire measurement probe (dedicated for grounded objects) was placed in Faraday cage. The measurement setup is presented in the photo below. The spectrum was acquired after 24 hours of exposition on 3% NaCl solution.  Top-left figure presents impedance modulus and top-right figure presents impedance angle for the measurements done using the setup presented in bottom-left figure (in the central part HIADAC could be seen).

title: MODALITY corpus - SPEAKER 09 - SEQUENCE S1

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.
The dataset consist of recordings and visual features for SPEAKER 09:
sex: man
native speaker: no
age: 29
The test material: SEQUENCE S1
All recordings for all speakers are available at http://www.modality-corpus.org/  Sample still from the corpus(SPEAKER 09) Due to the size of the corpus (approx. 2.5 TB of data), every speaker’s recording was placed in a separate zip file of the size approx. 4-7 GB each.
The recordings were organized according to the speakers’ language skills. The group A (17 speakers) consists of native-speakers. Non-native speakers recordings (Polish nationals) were placed in the Group B (25 speakers).
The audio files use the Waveform Audio File Format (.wav), and contain a single PCM audio stream sampled at 44.1 kSa/s with 16-bit depth. The video files utilize the Matroska Multimedia Container Format (.mkv) in which a video stream in 1080p resolution, captured at 100 fps was placed after being compressed with h.265 codec (using High 4:4:4 profile). The ‘.lab’ files are text files containing the information on word positions in audio files, and follow the HTK label format. Each line of a ‘.lab’ file contains the actual label preceded by start and end times (in 100 ns units) e.g. : 1239620000 1244790000 FIVE which denotes the word “five”, occurring between the 123.962 s and 124.479 s of audio.Word-accurate SNR values calculated for every recording are also included in the ZIP file.

title: Dataset of non-isomorphic graphs being coloring types (K4-e,Km-e;n), 2<m<7, 1<n<R(K4-e,Km-e)

description: For K4-e and Km-e graphs, the type coloring (K4-e,Km-e;n) is such an edge coloring of the full Kn graph, which does not have the K4-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(K4-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 K4-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 (K4-e,Km-e;n) exist for n&lt;R(K4-e,Km-e).
The dataset consists of:a) 3 files containing all non-isomorphic graphs that are coloring types (K4-e,K3-e;n) for 1&lt;n&lt;5,b) 8 files containing all non-isomorphic graphs that are coloring types (K4-e,K4-e;n) for 1&lt;n&lt;10,c) 11 files containing all non-isomorphic graphs that are coloring types (K4-e,K5-e;n) for 1&lt;n&lt;13,d) 15 files containing all non-isomorphic graphs that are coloring types (K4-e,K6-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.

title: Changes in school enrollment in 1990-2011 (higher ducation)

description: The measure of the universality of education are the enrollment rates. Over the past years, enrollment rates in higher education have more than quadrupled. The gross enrollment rate increased from 12.9% in the academic year 1990/1991 to 53.8% in the academic year 2010/2011, and net - from 9.8% to 40.8%, respectively. The gross enrollment rate is the ratio, expressed as a percentage, of all people studying at a given level to the total population of people who are nominally assigned to this level of education (19-24 years). On the other hand, the net enrollment rate is the ratio, expressed as a percentage, of the number of students at the nominal age of education at a given level to the entire population of people at the nominal age assigned to this level of education (19-24 years).

title: EH36 steel for shipbuilding - fracture documentation for CTOD test (plate thicnkness 30mm), a0/W = 0.6

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 = 0.60 specimen.

title: Images of topography and mechanical properties (phase imaging) of cast iron samples from water installations

description: Measurements in contact and semi-contact mode. NTEGRA Prima (NT-MDT) device. CSG 10.
The research was related to the project of monitoring the condition of sewage pipelines in the city of Gdańsk. In addition to typical corrosion tests, microstructural imaging was also performed using an atomic force microscope. The device allows to visualize the heterogeneity of the cast iron structure by means of topographic imaging. However, because topographic differences may also come from other sources (e.g. errors in the surface preparation process), additional measurements of the mechanical properties of the surfaces of the tested samples were made. By making the probe vibrate while in contact with the surface, it is possible to determine local changes in the hardness of the material by monitoring changes in the amplitude and phase of the oscillation. This technique allowed to distinguish areas with different mechanical properties, i.e. with a different structure. The heterogeneity of the microstructure of cast iron translates into its susceptibility to corrosion attack, i.e. the value important for the assessment of the service life of the tested pipelines. The file contains 21 images.

title: Ways to promote and increase the level of quality at private universities in Gdańsk, Sopot and Gdynia

description: To exist and develop, universities must first of all have someone to educate. With considerable market competition, they must undertake intense marketing activities to reach the client, i.e. the potential student. Moreover, such activities are the main goals of non-public universities and are taken into account when building a strategy. Research shows that each of the non-public universities undertakes intensive activities aimed at promoting their university, and their detailed activities are presented in this research data.

title: The changes of outlet gases concentrations from SOFC with Ce(Pr,Sm)O2-s layers

description: The dataset includes The changes of outlet gases concentrations from SOFC with Ce(Pr,Sm)O2-s layers. Samples were produced using aqueous soft chemistry methods (microemulsion method) and applied in form of a layer onto the anode of the commercial SOFC. The SOFC was working under biogas feeding.
"Simultaneously with electrical tests, an analysis of the composition of the outlet gases from SOFC was performed using a Fourier Transformed Infrared Spectroscopy (PerkinElmer Spectrum 100 with ZnSe optical windows). FTIR spectra were collected every 10 min within the wavenumber range of 4000–500 cm−1 with a resolution of 4 cm−1. Concentrations of methane, carbon dioxide and carbon monoxide were then calculated. Although H2 gas is not visible in FTIR spectra, after a calibration process, we were able to determine its concentration as a difference from 100% of summed CH4, CO2 and CO concentrations. Such an approach is correct and in line with expectations. "(Cyfrowy identyfikator dokumentu elektronicznego (otwiera się w nowej karcie)10.1016/j.ijhydene.2020.07.146)

title: AFM images of the platinum (111) single crystal surface as delivered, without the polishing treatment

description: Platinum (111) single crystal surface images as delivered, without polishing treatment. Topographic measurements in contact mode. NTEGRA Prima (NT-MDT) device. CSG probe 10.
Single crystals are an important research material due to their strictly defined structure, thus determining their electrochemical activity. They make it possible to study, for example, the course of electrode reactions or adsorption phenomena occurring on a specific ordered structure. Despite the defined crystallographic orientation, the factory single crystals are characterized by a noticeable surface roughness, which makes it impossible to perform, for example, adsorption imaging of inhibitor molecules. Atomic force microscopy allows to monitor of the state of surface preparation, expressed both in the form of statistical parameters and possible for visual observation. The file contains 18 images.
