title: The generalization by simplification operator with Chrobak’s method of objects representing groups of buildings in Katowice district - scale 1:10000

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 input data are building groups obtained as a result of the aggregation operator activity (KAT_10k_BuildingAggregation). The Chrobak's operator was designed to simplify lines [2]. For the purpose of simplifying buildings, this method has been adapted and extended by verifying the minimum size of the object using the cartographic matrix [3]. The resulting objects require another stage - orthogonalization. As a result of the simplification process, 1.5% of building groups have been removed.

title: MODALITY corpus - SPEAKER 07 - 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 07:
sex: man
native speaker: no
age: 28
The test material: SEQUENCE S1
All recordings for all speakers are available at http://www.modality-corpus.org/  Sample still from the corpus(SPEAKER 07) 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: Atomic force microscopy images of copper electrical contacts wear under the influence of friction

description: Measurement of wear of copper electrical contacts under the influence of friction. Imaging in contact mode in the variant of scanning spreading resistance microscopy. Additionally, there are spectroscopic current-voltage curves showing local changes in electrical conductivity. NTEGRA Prima (NT-MDT) device. Probe NSG 01Pt.
The images show the results of scanning the copper electrical contact areas used in the switches. As a result of use, there is a mechanical degradation of the electrical contact areas, affecting the deterioration of the device's performance. The microscale tests allowed to determine the microstructural details of the wear of the contact point between the contacts, expressed by the degree of abrasion of these surfaces. In addition, in the case of testing electrical conductivity, the atomic force microscopy technique can be supplemented with a variant of electrical measurement, which consists of applying a voltage between the conductive probe and the tested sample and measuring the resulting current. It is a measure of the local quality of electrical contact and can be expressed both as conductivity maps and local current-voltage curves. The file contains 18 images and 8 current-voltage curves.

title: Basic financial categories of non-public universities in 2010 (in PLN thousand)

description: In 2010, non-public universities achieved a positive gross and net financial result. In nominal terms, the net financial result decreased compared to 2009 by 43.7%. It was lower than the net financial result of public universities by PLN 348.3 million. and amounted to PLN 148.1 million. 
The financial result presented in the research data includes the university's gross financial result (profit or loss), which is the difference between total revenues and total costs incurred to obtain them, adjusted by the balance of extraordinary gains and losses. Extraordinary losses and gains are understood as the financial consequences of events occurring uniquely outside the ordinary activities of the university, in particular those of a random nature - often caused by the abandonment or suspension of a certain type of activity and settlement or remedial proceedings, and the net financial result (profit or loss) of the university, which is obtained by reducing the gross financial result by obligatory charges on the financial result. The main component of burdens on the financial result is income tax

title: Mechanical lithography in a polymer substrate using AFM in contact mode

description: Mechanical lithography in a polymer substrate. Contact mode. NTEGRA Prima (NT-MDT) device. NSG 01 probe.
In one of the easier lithographic techniques that can be implemented with an atomic force microscope, the probe tip is displaced under relatively strong loading forces, removing portions of compliant material along its path. This technique uses the plowing principle in the same way as a traditional tool: material is removed from the ground in a strictly defined manner, leaving a deep "excavation" with the desired layout. The presented results refer to the demonstration application of this type of lithography, however, the demonstrated technique can also be used in scientific applications, such as manipulation of graphene structures: B.
