We propose a neural network-based approach to calibrating stochastic volatility models, which combines the pioneering grid approach by Horvath et al. (2021) with the pointwise two-stage calibration of Bayer and Stemper (2018). Our methodology inherits robustness from the former while not...

In this paper we develop a valuation framework for a Proof-of-Stake (PoS) payment system. Active network participants (proposers and validators) are required to stake tokens, and receive payments in return for their services. This property of the PoS system connects cash flows to token holdings,...

The Commission Regulation (EU) 2016/631 of the 14th of April 2016 establishing a network code on requirements for grid connection of generators introduces a framework for building a structural harmonization of technical stipulations across Europe. Network operators must implement this regulation...

The number of prosumers -consumers equipped with decentralized production- is expected to increase following the revised Renewable Energy Directive (2018/2001) and the rising energy prices. The economic literature suggests there is room for demand-side storage that can take two forms:...

This research paper presents a novel approach for fault-tolerant Wireless Sensor Networks (FT-WSNs) designed for IoT applications. The approach addresses obstacle detection challenges in WSNs to ensure uninterrupted network operation and optimize energy consumption. A hexagonal topology...
