A Practical Attack on the MIFARE Classic [PDF]

open access: yesarXiv, 2008
The MIFARE Classic is the most widely used contactless smart card in the market. Its design and implementation details are kept secret by its manufacturer. This paper studies the architecture of the card and the communication protocol between card and reader.

Investigating the kinetics of small alcohol oxidation reactions using platinum supported on a doped niobium suboxide support

open access: yesElectrochemical Science Advances, EarlyView.
Abstract Platinum nanoparticles deposited on a silicon‐doped niobium suboxide support provided the catalyst known as Pt/NbOS. This was compared to the commercial Pt/C electrocatalyst in the ethanol and methanol oxidation reactions for use in direct alcohol fuel cells.

Data‐driven energy sharing for multi‐microgrids with building prosumers: A hybrid learning approach

open access: yesIET Renewable Power Generation, EarlyView., 2023
A hybrid learning approach is proposed in this study. XGBoost‐based demand response model of prosumers is first trained by supervised learning and then embedded into the MADRL environment. And an XGBoost‐embedded MADDPG algorithm is adopted to obtain the optimal scheduling strategy of MMGs with building prosumers through off‐line centralized training ...

An Improved Remote User Authentication Scheme Using Smart Cards [PDF]

open access: yesarXiv, 2005
In 2000, Hwang and Li proposed a new remote user authentication scheme using smart cards. In the same year, Chan and Cheng pointed out that Hwang and Li’s scheme is not secure against the masquerade attack. Further, in 2003, Shen, Lin and Hwang pointed out a different type of attack on Hwang and Li’s scheme and presented a modified scheme to remove its

Synthesis and Unveiling Properties of Nanocomposite NiO/Mn2O3 and Ni–Mn‐Based Layered Double Hydroxide as Efficient Supercapacitor Electrodes

open access: yesEnergy Technology, EarlyView.
The layered Ni–Mn layered double hydroxide and spherical‐like nanoparticle of NiO/Mn2O3 morphological images are shown. The prepared material, characterized by half‐cell studies, which shows spherical‐like NiO/Mn2O3, performs higher compared to other prepared samples.

Experimental results and technique evaluation based on correlation function for a backup protection of synchronous generator stator windings

open access: yesThe Journal of Engineering, Volume 2022, Issue 12, Page 1190-1207, December 2022., 2022
Abstract Unbalanced loads and faults cause power quality problems in power grids, which may lead to system elements failure, particularly to synchronous generators. Faults detection and identification of the disturbance severity level are essential in the grids. Important equipment are often protected with dual protection systems.

Morphological engineering for high‐performance perovskite field‐effect transistors

open access: yesFlexMat, EarlyView.
Abstract The emergence of perovskite semiconductors for field‐effect transistor (FET) applications has received significant research attention due to their excellent electronic properties. The rapid development of perovskite FETs over the last few years has been driven by advances in understanding the thin‐film morphologies of perovskite layers and ...
