title: The database of interpolated RR-intervals of original length 512 of 41 patients at rest hospitalized due to the episode of acute ischemic stroke

description: 


This dataset contains the data that was a basis for the results discussed in the paper “Persistent homology as a new method of the assessment of heart rate variability” by Grzegorz Graff, Beata Graff, Paweł Pilarczyk, Grzegorz Jabłoński, Dariusz Gąsecki, Krzysztof Narkiewicz,  Plos One (2021), DOI: 10.1371/journal.pone.0253851.
The file is in the csv (comma-separated values) format that is easy to import by most types of spreadsheet software. All the patients are identified by the string “STR” (for stroke) followed by a 3-digit identifier; note the non-contiguous numbering. The file contains original values of RRs (in milliseconds) after applying linear interpolation to those RRs that were not marked as normal. These sequences were used for the calculation of the standard frequency-domain indices. The first column contains identifiers of the patients.

title: Vident-lab: a dataset for multi-task video processing of phantom dental scenes

description: We introduce a new, asymmetrically annotated dataset of natural teeth in phantom scenes for multi-task video processing: restoration, teeth segmentation, and inter-frame homography estimation. Pairs of frames were acquired with a beam splitter. The dataset constitutes a low-quality frame, its high-quality counterpart, a teeth segmentation mask, and an inter-frame homography matrix. The homography warps the current frame to the previous frame with respect to the teeth. Moreover, we provide the list of human-annotated segmentation masks so that future segmentation methods can adhere to our evaluation protocol and compare their results to MOST-Net in [1]. The remaining segmentation masks were obtained with HRNet48. The dataset has the training, validation, and test sets of 300, 29, and 80 videos, respectively.

title: Dataset for a research study on scientific productivity of Polish technical universities (Koszalin University of Technology 2016-2020).

description: This dataset was created for the purpose of research on scientific productivity at Polish technical universities. The raw data was retrieved in June 2021 by the SciVal benchmarking tool in xlsx format and will be used to create the research profiles of the universities and underlying data of journals articles. The most common definition of research productivity (interchangeable with academic productivity or scientific productivity)  states as research productivity are the number of publications per researchers. However, a more extended definition of scientific productivity, connecting quantity and quality approach involves producing quality research represented by publishing academic papers in reputable international journals, citing these papers, gaining research funding (e.g. national and international grants), and collaborating in scientific teams.
The dataset prepared for the scientific profile of  Koszalin University of Technology consists records from 2016-2020:

title: Optical measurements of lithium titanate sol-gel derived thin films

description: Nanocrystalline thin films with 800 nm thickness were prepared by sol–gel method. To examine the influence of the annealing time on as-prepared films crystallization, the coatings were heated at 550 °C for 10, 20 and 80 h. On the basis of transmission characteristic optical properties were calculated. It was found that transmission through the thin films was reduced and position of the fundamental absorption edge was shifted toward a longer wavelength with increasing of annealing time. The optical band gap was calculated for direct allowed and indirect allowed transitions from optical absorption spectra.

title: Self-Censorship in a Workplace: The Role of Gender, Management Position, Procedural Justice and Organizational Climate

description: Data consist of three studies. In study 1 (N = 948) we test whether women manifest more self-censorship than men and we verify whether this effect is maintained when women and men hold managerial position. Then, we analyse the effects of procedural justice (study 2, N = 98) and communal organizational climate (study 3, N = 567) on women’s and men’s self-censorship.
Three items of the acquiescent silence subscale of the Four Forms of Employee Silence Scale (Knoll & van Dick, 2013, adapted by Adamska & Jurek, 2017) were used to gauge self-censorship. Procedural justice was measured using a seven-item scale developed by Colquitt (2001), and adapted for the Polish population by Retowski, Adamska, and Konarski (2017). Emotional attitude toward an organization was measured by the Positive and Negative Organizational Attitudes Scale (PNOAS) developed by Jurek and Adamska (2017). The 12 items were used to asses the extent to which respondents perceive their organizations and work environment as communal and agentic.

title: Mechanical properties of VL E27 steel for shipbuilding – impact in test +20°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  +20°C.
