One of the key aspects of the current research trends for the future smart grid is the possibility of devising distributed algorithms for solving a global problem. This corresponds to the idea of a decentralized access to generation/storage resources, as well as to the much more challenging task...
while digital signatures can secure transaction information. For example, the consensus algorithm used in the Bitcoin network is proof of work (PoW)1, which allows every miner to compete through computing power based on
It is essentially a distributed database that integrates distributed computing, cryptography, network transmission and other technologies and is decentralized, tamper-proof, programmable and traceable2,3,4. The research on consensus algorithms started before the emergence of blockchain technology, and as ...
The research on ordering methods amongZ-numbers is a common topic in the literature, mainly due to the multiple applications that this linguistic model has. For instance, in the case of a classical multicriteria decision making problem, a hierarchical order is established among the alternatives acc...

, the desired accuracy for both the upper- and the lower-level dual problems is reached. In fact, as done in the proof of Theorem2, and considering Proposition2, we have: where the first equality is due to Proposition1, and the last inequality follows from\(i \ge {\bar{I}}_{\max...
The first application of the blockchain, Bitcoin, uses the Proof of Work consensus mechanism. Briefly introduce the consensus mechanism of Bitcoin. For the specific details of the algorithm, you can check the white paper. After a node receives a transaction, it will verify the validity of the...
Distributed graph exploration Rotor-router Cover time Collaborative robots Parallel random walks Derandomization 1. Introduction In graph exploration problems, a walker or group of walkers (agents) is placed on a node of a graph and moves between adjacent nodes, with the goal of visiting all the ...
This paper shows that the inverse chirp z-transform (ICZT), which generalizes the inverse fast Fourier transform (IFFT) off the unit circle in the complex plane, can also be used with chirp contours that perform partial or multiple revolutions on the uni
