Protection System Against Products Counterfeit Based on NFC and Barcode Technologies
Education - Technology - Computer Science. 2017. Vol. 4. No. 22. P. 368–374.
The objective of this report is to provide a protective system architecture and analysis for NFC and Barcode technology that can be use to empower consumer in the fight against counterfeiting and IPR infringing products using mobile devices. This report focuses on the technology that can empower the consumer in the field in the presence of the goods itself by using technical tools and devices, which are easily available. The report identifies the main immediate empowerring tool for consumers. This is represented by a modern smartphone (or similar device like a tablet) to be use as a tool to empower the consumer in the fight against counterfeiting. The modern smartphone is equipped with a high resolution camera, support for different standards for wireless connectivity, a powerful processor able to support the implementation of sophisticated algorithms and support for NFC and Barcode readers. In addition, the smartphone can be integrated and augmented with a wide range of plug-in devices and tools (e.g., an USB microscope). The concept of empowering the consumer can be an important element to support Due Diligence practices and Supply Chain Integrity because the different categories of consumer can authenticate the goods in different parts of the supply chain and report the presence of non-compliances (e.g., counterfeit products).

We perform a Monte Carlo analysis of the Ising model on many three-dimensional lattices. By means of finite-size scaling we obtain the critical points and determine the scaling dimensions. As expected, the critical exponents agree with the three-dimensional Ising universality class for all models. The irrelevant field, as revealed by the correction-to-scaling amplitudes, appears to ...

We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Svendsen-Wang and Wolff cluster algorithms. We examine the dynamics of these algorithms for two models in different universality classes: the Ising model and the Potts model with three components. The overlap of two ...

Background. In the context of a fast-paced lifestyle and high stress levels, assessing and managing psycho-emotional states has become an important task. Traditional methods, such as questionnaires, have limited accuracy due to the subjectivity of data, whereas physiological approaches, including the measurement of galvanic skin response (GSR), provide an objective assessment. However, existing devices for ...

We investigate the boundary separating regular and chaotic dynamics in the generalized Chirikov map, an extension of the standard map with phase-shifted secondary kicks. Lyapunov maps were computed across the parameter space (K,K(α, τ)) and used to train a convolutional neural network (ResNet18) for binary classification of dynamical regimes. The model reproduces the known critical ...

Background and purpose
Technology acceptance has been researched for decades. While some technologies are widely accepted, others are perceived as a threat, such as microchip implants. In this study, a two-step structural equation modeling approach was used to evaluate a new research model on microchip implant acceptance.
Methodology
A structural equation modeling model was developed to identify what ...

In this study, we analyze the dielectric function of high-Tc cuprates as a function of doping level, taking into account the full energy band dispersion within the CuO2 monolayer. In addition to the conventional two-dimensional (2D) gapless plasmon mode, our findings reveal the existence of three anomalous branches within the plasmon spectrum. Two of these branches ...

The development of new algorithms for simulations in physics is as important as the development of new analytical methods. In this paper we present a comparison of the recently developed microcanonical population annealing (MCPA) algorithm with the rather mature Wang-Landau algorithm. The comparison is performed on two cases of the Potts model exhibiting a first ...

Nabokoite family compounds ACu7(TeO4)(SO4)5Cl (A=Na, K, Cs, Rb) are one of the candidates for the evasive spin-liquid state predicted for highly-frustrated square kagome lattice (SKL). Their magnetic subsystem includes SKL layers decorated by additional copper ions. All members of this family are characterized by quite high Curie-Weiss temperatures (∼80−200 K), but magnetic ordering was reported ...

A detailed investigation of a superconducting spin-triplet valve is presented. This spin-valve consists of a superconducting film covering a metal with an intrinsic spiral magnetic order, which could result from competing isotropic exchanges or, if the crystal lattice breaks central symmetry, from asymmetric Dzyaloshinskii-Moriya exchange. Depending on the anisotropy, such a metal may change its ...
