title: Mechanical properties of VL E27 steel for shipbuilding – impact in test -60°C, 3D model of fracture

description: One of the basic divisions of steels used for ship hulls and ocean engineering structures is the division into: normal strength steels, high strength steels and extra high strength steels. The belonging to the group is determined by the mechanical properties of the steel, such as: yield point, ultimate strength and plastic elongation after fracture. The steels in each group are divided into categories, differing in the minimum required breaking energy at a specific temperature, determined in the Charpy test. For applications on a more responsible hull structure or offshore structure, additional steel tests may be required - determination of fracture toughness. In the shipbuilding industry, it is most often CTOD (Crack Tip Opening Displacement) test.
The published data concern testing the fracture toughness of VL E27 steel for shipbuilding, with  nominal thickness of 35 mm. It is the first steel from the group of high strength steels. It is characterized by an early low carbon content, as for hull steels, which is one of the reasons for its high ductility. The average carbon content in the tested material was 0.16%. The scope of the tests carried out so far is: tensile test at + 20 ° C, 0 ° C, -20 ° C, impact test at temperatures: 20 ° C, 0 ° C, -20 ° C, -40 ° C, - 60 ° C and a fracture toughness test at temperatures of 20 ° C, 0 ° C, -20 ° C.
Dataset contains fracture documentation - high resolution photography and 3D model (cloud of points) of fracutre. Charpy impact test temperature  -60°C.

title: Sulfammox process_task 1

description: Anaerobic ammonia-oxidizing bacteria have a more comprehensive metabolism thanexpected - there may be other electron acceptors that oxidize ammonium nitrogen under anaerobicconditions, in addition to the well-known nitrite nitrogen, one of which is sulfate in the sulfammoxprocess. Sulfate-containing compounds are part of the medium for the anammox process, but theirconcentrations are not particularly high (0.2 g MgSO4 ∙ 7H2O/dm3 and 0.00625 g FeSO4/dm3). Theycan react to some extent with influent ammonium nitrogen. In this work, tests were carried out intwo sequencing batch reactors with granular sludge. The first reactor (R1) operated in a 6 hour cycle,and the concentration of the inflowing sulfate was kept at 44 mg/dm3∙d. The second reactor (R2) wasoperated until the 36th day in a 6 hour cycle; the influencing concentration was 180 mg SO42−/dm3∙dfrom the 37th to 64th day in a 3 hour cycle, with an influencing concentration of 360 mg SO42−/dm3∙d;and from the 65th to 90th day, the reactor was operated again in a 6 hour cycle with an influencingconcentration of 180 mg SO42−/dm3∙d. Along with the increased share of sulfate, both the ammoniumutilization rate and specific anammox activity showed an increasing trend. As soon as the sulfatedosage was reduced, the ammonium utilization rate and specific anammox activity values dropped.Therefore, it can be concluded that sulfate-containing compounds contribute to the efficiency andrate of the anammox process.

title: The radiated immunity test of an astable multivibrator for various supply voltages

description: The dataset presents a result of measurements that are a part of electromagnetic field immunity tests. The radiated, radio frequency, immunity tests were carried out for a typical astable electronic multivibrator supplied from a power supply with an output voltage of 6V and 7.5 V. Tests of immunity of electronic systems to radiated radio frequency (RF) disturbances were performed with measurement set up under the requirements specified in the electromagnetic compatibility (EMC) standards.
In laboratory conditions, the electromagnetic fields were simulated in the GTEM (Gigahertz Transverse Electromagnetic) cell (Fig. 1). An integrated signal generator, equipped with a built-in 45 W class A power amplifier module, was used in the measurement setup. The tested multivibrator was supplied externally from the NDN DF1723003TC power supply for the output voltage of 6V and 7.5 V. The signal cable connected to the input of an oscilloscope was led out of the tested PCB. The measurement process was controlled by the WIN 6000 software installed on a personal computer connected to the signal generator via the IEEE488 interface.
A typical astable multivibrator was equipment under test (EUT) in the immunity measurements. The proper operation of the device is indicated by flashing LEDs with variable frequency. The system sensitivity to the radiated field in the GTEM cell was assessed based on the observation of the differences in the shape between the signal waveform controlling diode switching and the reference waveform recorded with the signal generator turned off.
The measurements were executed at a normative field strength of 10 V/m. The RF signal was modulated with a sinusoidal signal with a frequency of 1 kHz and a modulation depth of 80%.
For output voltage of the power supply equal to 6 V, the test procedure was carried out in the frequency range starting at 80 MHz and incrementing in 10% steps up to at least 1 GHz. Next, the frequency range was narrowed down to 100-300 MHz and the frequency step was reduced to 1%. The position of the equipment under test in the uniform area of the GTEM cell was changed for three orthogonal orientations x, y, z.  Figure 1. Configuration of the measuring system for testing the immunity of electronic systems in the GTEM cell For the output voltage of the power supply equal to 7.5 V, the measurement was performed only in the vertical position of the EUT (axis y) (Fig. 2). First, the test procedure was carried out in the frequency range starting at 80 MHz and incrementing in 10% steps up to at least 1 GHz. Then, the upper frequency was lowered to 300 MHz and the frequency step was reduced to 1%.
The attached files contain oscillograms showing the voltage waveforms recorded from the PCB. For each case, information about the RF frequency of the signal generator is included in the file description.

title: MODALITY corpus - SPEAKER 35 - COMMANDS C3

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 35:
sex: woman
native speaker: yes
age: 43
The test material: COMMANDS C3
All recordings for all speakers are available at http://www.modality-corpus.org/  Sample still from the corpus(SPEAKER 35) 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.264 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.
