title: The low-frequency magnetic field emissions on-board of the vessel

description: The data represents measurement results performed on board of the vessel. The acquired time-waveforms, corresponding to the instantaneous values of the magnetic field (MF) induction were acquired near the cable supplying the bow thruster motor. Data recording of the magnetic field density (MFD) emissions was carried out with a/d converters of the data acquisition board (DAQ), which was connected to the analog outputs of an isotropic field meter. A block diagram of the measuring system is presented in Figure. ESM-100 H/E field meter, which was applied in this system, enables the measurements of MFD in the measuring ranges from 1 nT to 20 mT. Four wide-band (5 Hz - 400 kHz) analog outputs of this meter afford possibilities for measuring the time waveforms of the magnetic fields, separately in the three orthogonal directions, in the output voltage range from 0 to 600 mV, with resolution 1 nT=30 mV. The multifunction DAQ board processes the analog signal with an 18-bit resolution and sampling rate up to 625 kS/s. The onboard lowpass filter with programmable cut-off frequency (up to 40 kHz) rejects high-frequency noise and prevents aliasing. Discrete signals are next analyzed (off-line) with the use of virtual instruments (VIs) in the LabVIEW environment. The digitized measuring signal is initially recorded by the VIs that perform data acquisition with repetition controlled programmatically. The sampling frequency is equal to 20 000 Hz and is inserted in the first row of the attached file.
The results of the preliminary measurements of MFD emissions, which are caused by running frequency converter confirmed that the MFD spectrum depends strongly on frequency. The magnetic field spectrum spreads out mainly in the low-frequency range below 2 kHz. The presented measurements and analyzing were performed within the frequency range from 5 Hz up to 2 kHz.

title: X-ray images of Baltic herring. Data analysis

description: Based on the developed methodology for the: (i) optimal method of catching, (ii) transporting and storing fish, (iii) measuring and (iv) analyzing X-rays images, the existing collection of X-ray images of Baltic herring, caught in October 2002 during the Swedish component of the Baltic International Acoustic Survey (BIAS) in the Baltic proper (ICES Subdivisions 25, 27 and 29), has been expanded to include of X-ray images of herring from the Polish coastal zone (ICES Subdivision 26).
Newly received X-ray images were used to measure the geometric dimensions of swimbladders. Detailed data on the shapes and geometric sizes of herring bodies and swimbladders for dorsal exposure were obtained for 74 fish individuals.
These data were used as the input data in the modelling of the backscattering characteristic of the herring from the Polish coastal zone in order to define the TS(L) relationship, critical to abundance estimation from fisheries acoustic surveys.

title: Hanow - Praecepta de arte disputandi - transcription and photographs

description: Praecepta de arte disputandi by Enlightenment Gdańsk scholar Michael Christoph Hanow (1695-1773) are a combination of rhetorical theory and practical tips on how to effectively conduct discussions.   
The Praecepta, together with two other works of Michael Christoph Hanow, are part of the manuscript book kept in the collection of the PAS the Gdańsk Library (reference number Ms. 512) [the Polish Academy of Sciences the Gdańsk Library]. The record was made by Konstantin Ernst Groddeck, who came from a wealthy merchant family settled in Gdańsk.
The text of the Praecepta was divided into small parts, marked with a paragraph symbol. In addition, Michael Ch. Hanow applied a four-part higher level division. The titles of individual subchapters:
General principles of conducting a discussion,
General rules for all participants to a discussion,
Detailed rules for the parties to a discussion,
Ways of replicating arguments that are difficult to refute.
The text presented is a transcription from the autograph manuscript of Konstantin Ernst Groddeck. This is the first version, which in several places skips hardly illegible words. Work is underway to supplement these gaps. The text of the precepts in its entirety will appear in the next, separate research data set. In the current version, the spelling has been modified, based on the Latin dictionaries used today. Changes in punctuation have also been applied, basically giving up the rhetorical punctuation. The differences between punctuation of the original and the transcription can be confronted by viewing the photographs of the manuscript pages contained in this data set.

title: The voltage on bus bars of the main switchboard of the ferry electrical power system during a layover at the port

description: The dataset is part of the research results on the quality of supply voltage on bus bars of the main switchboard of the ship's electrical power system in different states of ship exploitation. The attached dataset contains the measurement results carried out onboard the ferry during a layover at the port.
The ferry is equipped in a three-phase, three-wire electrical power system. The source of energy is three-phase synchronous generators driven by auxiliary diesel engines. Additionally, shaft generators driven by the propeller shaft of the main engine are used. The ship's electrical power plant consists of three free-standing generators of 1400 kVA each, and two shaft generators 1375 kVA each. The nominal voltage on bus bars of the main switchboard was 380 V with a frequency equal to 50 Hz. The free-standing generators have been the main energy source. The parallel operation of each shaft generator with the free-standing generators is possible, especially during a sea voyage with a calm wave surface. Additionally, each of the bow thrusters has been supplied of a single shaft generator, the most frequently, in configuration separated from the main electrical power system. The voltage of 220V has been obtained using a transformer.
The voltage waveforms on bus bars of the main switchboard were recorder with the digital measuring system, which allows the simultaneous measurement of three phase-to-phase or two-phase voltages. The initial conditioning of the input signals is carried out by optoisolation amplifiers and a low-pass filter module (antialiasing). The formation of the output digital signal from the analog signal takes place in the a/d converter with a resolution of 16 bits and a sampling rate of up to 20 kS/s. Using three channels at the same time allows the maximum sampling rate of 6.6 kS/s. The block diagram of the digital measuring system is shown in Figure.
The files contain voltage waveforms of the output of a/d converters in [V], in three phases for the 380 V network. The attenuation and offset of the measuring path for the 380 V network are equal to 134.0123 [V / V] and -0.0175 V, respectively. The sampling frequency is inserted in the first row of the attached file.  The block diagram of the digital measuring system

title: EH36 steel for shipbuilding (plate thicnkness 30 mm) - 3D fracture scan

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 3D scan of fracure (claud of points) of 3 point bend specimen (a0/W = 0.50). 
Data can be use for checing correctness of numerical models of frecture
