title: EH36 steel for shipbuilding - fracture documentation for CTOD test (plate thicnkness 40mm), 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: MODALITY corpus - SPEAKER 04 - 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 04:
sex: man
native speaker: no
age: 25
The test material: SEQUENCE S1
All recordings for all speakers are available at http://www.modality-corpus.org/  Sample still from the corpus(SPEAKER 04) 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 (K3-e,Km-e;n), 2<m<8, 1<n<R(K3-e,Km-e)

description: For K3-e and Km-e graphs, the type coloring (K3-e,Km-e;n) is such an edge coloring of the full Kn graph, which does not have the K3-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(K3-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 K3-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 (K3-e,Km-e;n) exist for n&lt;R(K3-e,Km-e).
The dataset consists of:a) 1 file containing all non-isomorphic graphs that are coloring types (K3-e,K3-e;n) for 1&lt;n&lt;3,b) 3 files containing all non-isomorphic graphs that are coloring types (K3-e,K4-e;n) for 1&lt;n&lt;5,c) 5 files containing all non-isomorphic graphs that are coloring types (K3-e,K5-e;n) for 1&lt;n&lt;7,d) 7 files containing all non-isomorphic graphs that are coloring types (K3-e,K6-e;n) for 1&lt;n&lt;9,e) 9 files containing all non-isomorphic graphs that are coloring types (K3-e,K7-e;n) for 1&lt;n&lt;11.

title: Microscopic examination of CuNiFeR pipeline

description: Copper and nickel alloys called cunifers (Cu, Ni, Fe and R – rest of alloy elements) have found wide application in the production of ship pipeline components in contact with sea water, such as, for example, the main engine cooling system. These alloys are characterized by a very high corrosion resistance, which is ensured by appropriately carried out passivation. However, with improperly carried out passivation, this material loses its anti corrosion properties and is often corroded. In addition, a mistakenly conducted welding process is a factor conducive to degradation processes. The purpose of this work is to show the impact of errors created during the production process and pipeline testing for its technical condition. The subject of the research was a fragment of the pipeline made of CuNi10Fe1,6Mn alloy, coming from a vessel floating on sea waters. Macro and microscopic examinations revealed a number of technological defects that affected the degradation of this element.
Dataset contains extended photographic documentation of exterminated part of pipeline.

title: Carbon (II) oxide (CO) calibration set of FTIR spectra

description: The calibration spectra for CO concentration calibration were supplied with this dataset 
Description of the procedure:
"In the calibration procedure, the system shown in Fig. 2 was used. The calibration mixture was composed of a dilution gas (Ar) mixed with CO2, CO or CH4. The concentration of these gases was varied using two mass flow meters. Such setup allowed obtaining particular calibration points. The resulting mixture was delivered directly to the FTIR cell. The measurement was carried out using the PerkinElmer Spectrum 100 spectrometer with a 10 cm path length gas cell and ZnSe windows. The spectra were collected at 4 cm1 resolution. At the beginning of the investigation, the FTIR cell was purged with argon. Then the desired mixture of gases with a total flow of 30 ml/min was supplied to FTIR for 10 min in order to reach a stable gas composition. Next, ten spectra were collected at every 2 min."

title: The number of students in public and private universities in 1990-2011

description: From the 2005/2006 academic year - when the number of students reached a record value of 1,953.8 thousand - the number of students is systematically decreasing. Within 5 years, this number decreased by 5.8%, and over the last year, the decrease amounted to 3.1%. These changes are related to the constantly decreasing number of people aged 19-24. Despite this, in some types of schools, such as universities / medical academies, schools of the Ministry of National Defense, as well as internal affairs and administration, the number of students increased.
