Zjawisko wirtualizacji pieniądza w warunkach polskich
2017
Pieniądz jest elementem gospodarki od wieków. Przez ten czas jego forma ewoluowała od prymitywnych produktów do banknotów i monet. Współcześnie coraz powszechniejsze staje się korzystanie z pieniądza elektronicznego, a nawet pieniądza wirtualnego. Pojawiają się zatem pytania, jak ten pieniądz działa, czy pełni takie same funkcje jak tradycyjny pieniądz i czy na pewno jest istotną alternatywą dla obecnie funkcjonującego pieniądza fiducjarnego. W tym kontekście rodzi się pytanie, czy system finansowy w obecnym kształcie może nadal funkcjonować, czy też będzie raczej ewoluować w kierunku systemu opartego na walucie wirtualnej. Celem opracowania jest próba przedstawienia pieniądza wirtualnego j…
Electoronic Performance Monitoring in Call Centers: An Ethical Decision Model
2013
Ever since it emerged on a widespread basis in the 1990s, electronic performance monitoring of employees has received significant scrutiny in the literature. Call centers have been the focus of many of these studies. This particular study addresses the issue of electronic performance monitoring in call centers from an ethical perspective. The following ethical dilemma is offered: "Is it ethical for a call center manager to evaluate the performance of a call center employee using electronic performance monitoring data gathered on the employee?" Using utilitarian, Kantian, virtue, and covenantal ethical theories, the study proposes an ethical decision model and subsequently applies the model …

Visualization of Moiré Magnons in Monolayer Ferromagnet
2023
| openaire: EC/H2020/788185/EU//E-DESIGN Two-dimensional magnetic materials provide an ideal platform to explore collective many-body excitations associated with spin fluctuations. In particular, it should be feasible to explore, manipulate, and ultimately design magnonic excitations in two-dimensional van der Waals magnets in a controllable way. Here we demonstrate the emergence of moiré magnon excitations, stemming from the interplay of spin-excitations in monolayer CrBr3 and the moiré pattern arising from the lattice mismatch with the underlying substrate. The existence of moiré magnons is further confirmed via inelastic quasiparticle interference, showing the appearance of a dispersion …
Design and Performance Evaluation of a High Power-Density EMI Filter for PWM Inverter-Fed Induction-Motor Drives
2016
This paper presents the design of an electromagnetic interference (EMI) filter for a low-voltage high-current induction-motor drives supplied by dc power grids. In order to effectively design the EMI filter, a suitable common-mode/differential-mode (CM/DM) separation technique has been used. Due to the high operating currents, the software-based separation technique using time-domain measurements has been applied. The proposed technique allows the CM and DM sections of the EMI filter to be properly selected in a more economical way, i.e., without the need of a dedicated hardware or costly radio frequency (RF) instrumentation. The design has been done according to a power-density criterion. …
Hands-feet wireless devices: Test-retest reliability and discriminant validity of motor measures in Parkinson's disease telemonitoring
2022
Background Telemonitoring, a branch of telemedicine, involves the use of technological tools to remotely detect clinical data and evaluate patients. Telemonitoring of patients with Parkinson's disease (PD) should be performed using reliable and discriminant motor measures. Furthermore, the method of data collection and transmission, and the type of subjects suitable for telemonitoring must be well defined. Objective To analyze differences in patients with PD and healthy controls (HC) with the wearable inertial device SensHands-SensFeet (SH-SF), adopting a standardized acquisition mode, to verify if motor measures provided by SH-SF have a high discriminating capacity and high intraclass corr…

Quaternary Reversible Circuit Optimization for Scalable Multiplexer and Demultiplexer
2023
Information loss is generally related to power consumption. Therefore, reducing information loss is an interesting challenge in designing digital systems. Quaternary reversible circuits have received significant attention due to their low-power design applications and attractive advantages over binary reversible logic. Multiplexer and demultiplexer circuits are crucial parts of computing circuits in ALU, and their efficient design can significantly affect the processors’ performance. A new scalable realization of quaternary reversible 4×1 multiplexer and 1×4 demultiplexer, based on quaternary 1-qudit Shift, 2-qudit Controlled Feynman, and 2-qudit Muthukrishnan-Stroud gates, is presented in …
Highly-parallelized simulation of a pixelated LArTPC on a GPU
2023
The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The alg…
