title: The conducted immunity test of a power supply unit in accordance with EMC standards

description: The dataset presents a result of measurements that are a part of immunity tests to conducted disturbances, induced by radio-frequency fields. The immunity tests were carried out on the mains cable of the DF1723003TC NDN power supply. Tests of immunity of electronic systems to conducted disturbances in the frequency range from 150 kHz to 230 MHz are performed under the requirements specified in the electromagnetic compatibility (EMC) standards.
The source of the disturbance is an electromagnetic field coming from intended RF transmitters generating an RF signal, which is modulated with a 1 kHz sinusoidal tone at 80% depth. The normative test procedure was carried out in the frequency range starting at 150 kHz and incrementing in 1% steps up to at least 230 MHz. The integrated signal generator Teseq NSG 4070-45, equipped with a built-in 45 W class A power amplifier module, was used in the measurement setup. The coupling-decoupling network CDN M016 directly injects RF voltages into the cables under test. During the measurements, on the oscilloscope Rohde&Schwarz RTE 1102 the differences in the shape of the voltage waveform to the reference waveforms recorded with the RF signal generator turned off were being observed. The power supply unit and the oscilloscope are connected to the network via artificial networks Rohde Schwarz ENV432. The measurement process was controlled by the WIN 6000 software installed on a personal computer connected to the signal generator via the IEEE488 interface. The test set-up is shown in Fig.1.
Immunity tests were carried out for three different RF voltage levels: 1 V, 3 V and 10 V. The voltage generated by the power supply unit was 1 V, 10 V, 20 V and 30 V respectively.
The attached files contain oscillograms showing the voltage waveforms at the output of the power supply unit that deviates the most from the reference waveform. Additionally, a table with the measurement results is included.  Figure 1. Configuration of the measuring system for the immunity test

title: Morse decompositions for a non-linear Leslie population model with 3 varying parameters

description: This dataset contains selected results of rigorous numerical computations conducted in the framework of the research described in the paper "A database schema for the analysis of global dynamics of multiparameter systems" by Z. Arai, W. Kalies, H. Kokubu, K. Mischaikow, H. Oka, P. Pilarczyk, published in SIAM Journal on Applied Dynamical Systems (SIADS), Vol. 8, No. 3 (2009), pp. 757–789, doi: 10.1137/080734935.
The parameter space [8,37]✕[3,50]✕[0.5,0.9] was sampled at the resolution of 80✕80✕40. The phase space was sampled at the resolution of 2048✕2048. A collection of isolating neighborhoods that enclose Morse sets in a Morse decomposition was computed for each box of parameters, and a Conley-Morse graph was determined, with the Conley indices of the Morse sets computed where feasible. Clutching graphs between Morse decompositions found for adjacent boxes were also computed, and the parameter space was subdivided into classes of equivalent Morse decompositions, as described in the paper. The parallelization framework introduced in the paper "Parallelization method for a continuous property" by P. Pilarczyk was used in the computations, as published in Foundations of Computational Mathematics, Vol. 10, No. 1 (2010), 93–114, doi: 10.1007/s10208-009-9050-8.
The dataset contains the Morse decompositions found for all the parameter boxes. A collection of combinatorial Morse sets, that is, isolating neighborhoods of the actual Morse sets in each Morse decomposition, is encoded in terms of a PNG image. In this image, a single pixel corresponds to a square in the phase space. All the images are compressed together in the zipped archive file. The name of each file is in the format "pn_m_k.png", where n,m,k are the integer coordinates of the parameter box in the ranges: [0,79], [0,79], and [0,39], respectively. Each image is cropped in order to avoid the vast white area around the sets. Each combinatorial Morse set comprises of a collection of pixels drawn in a specific color. The colors used for the consecutive sets are listed at the bottom of the image as squares: black, blue, red, green, etc. The order is the same as in the corresponding Conley-Morse graphs available in a separate dataset. Note that the first set (black) is often a very small neighborhood of the origin that can be spotted as a single pixel at the bottom left corner of the image.
An interactive browser of all the Conley-Morse graphs and phase space portraits of the Morse decompositions provided in the current series of datasets is available at the address http://www.pawelpilarczyk.com/database/.

title: The electrochemical response to BDD electrode functionalization with ACE2 receptor

description: This dataset contains the results of the electrochemical impedance spectroscopy (EIS) measurements of the boron-doped diamond (BDD) electrode functionalization with ACE2 receptor. The functionalized electrode was then used for the electrochemical detection of the SARS-CoV-2 virus S1 protein. 
All electrochemical measurements were carried out in a three-electrode system using a potentiostat SP-300 (Biologic) / PalmSens4. The electrolyte was 1 mM K3[Fe(CN)6] and 1 mM K4[Fe(CN)6] in PBS (pH 7.4), deoxidized by passing through a stream of argon prior to measurement. The electrolyte volume was 1 mL. A platinum wire was used as the counter electrode. The reference electrode was a silver chloride electrode with an Ag|AgCl|3M KCl. The working electrode was the functionalised BDD with an electrolyte-exposed surface area of 0.196 cm2. Cyclic voltammetry (CV) measurements were performed from -0.5 to +0.75 V vs. Ag|AgCl|3MKCl with a polarisation rate of 50 mV/s over three cycles. Electrochemical impedance spectroscopy (EIS) measurement was performed for the sample polarised for 30 s to the potential E0’ before the measurement. The measurement was performed in the frequency range from 10 kHz to 0.1 Hz at 11 points per decade. The amplitude of the excitation signal was 10 mV. The procedure details are placed in the metadata.txt file.
The dataset is a part of the results published in the Sensors and Actuators B journal: DOI: 10.1016/j.snb.2022.132427

title: Effect of particle size of aluminosilicate microspheres on the change of hydration heat of cement mortars and selected physical, chemical, and mechanical properties.

description: This subject of the work is the study of selected properties of cement mortars containing two fractions of aluminosilicate microspheres with grain size in the range of 125 to 250 μm and from 250 to 500 μm. Mortar mixtures with ordinary Portland cement (OPC 42.5R) and three substitution rates of cement by microspheres, 1.5%, 3.5%, and 5.0%, were investigated. For all cement mixes, the constant water–binder ratio (w/b) equal to 0.50 was used. The research program included the determination of chemical and phase composition, as well as select physical properties of the tested material. The heat of hydration was determined for the initial time (7 days) of samples curing at 23oC. The analysis showed that the micro-spheres consist of three main elements: silicon, aluminum, and iron, whose oxides constitute about 89% of the material. The compressive strength showed that the addition of aluminosilicate microspheres with a grain size below 250 μm increases cement mortars’ strength compared to the control mortar and cement mortars with a grain size above 250 mm. The total cumulative heat, measured in cement mortars at 7 days, ranges from 280.1 to 249.2 J/g for the grain sizes below 250 μm and from 298.5% to 266.4 % for the grain sizes above 500 μm and is higher for the control mortar. The aluminosilicate microspheres with a particle diameter of &lt; 250 μm have a relatively high level of activity pozzolanic at 28 days compared to particles with a diameter of &gt; 250 mm. The SEM analysis proved that the use of microspheres of grain size below 250 mm increases the CSH phase in the structure of cement mortars at 7 days. This is not only due to the much smaller particle size of FAM but also because of its higher calcium oxide (CaO) content compared with FAM of grain size up to 500 μm

title: Refractive index measurement  in the range of 1.3 – 1.5  for 1550 nm wavelength (1st serie)

description: The low-coherence refractive index measurements of certified liquid samples provided by Cargille Labs were performed. The measurement system consisted of a broadband light source (central wavelength of 1550 nm), an optical spectrum analyzer, a 2x1 fiber-optic coupler (50:50 power split), and single-mode telecommunication optical fibers. A micromechanical setup served for positioning and stabilizing the measurement head. The measurement head was constructed as a Fabry-Perot cavity formed between the polished fiber end-face and a surface of a silver mirror. The sensor was operating in a reflecting mode. The cavity length was set to 280 µm; the measurements of refractive index were performed in the range of 1.3 – 1.5 with an increment equal to 0.01. Two series of 10 spectra measurements for each liquid were carried out. A reference signal with a cavity filled with air was recorded to confirm its intact setting after cleaning and changing the liquid inside the cavity.
 
The Folder name indicates the nominal refractive index of the measured liquid sample.The Files named W0000-W0010 in each folder are subsequently recorded spectra for the given sample.REF files are reference measurements taken for air filling the cavity of the same length.
The liquids are in the refractive index range of 1.3-1.5 with an increment of 0.01.The cavity length was set to 280 um.  The measurement set-up.
