Battery Energy Storage Optimization for Enabling Black Start in Offshore Wind Farms
Abstract: The transition toward power systems dominated by renewable energy sources (RES) introduces significant challenges to the provision of black start services. Black start units are essential for restoring power following a system-wide outage; however, the gradual retirement of conventional generation reduces the availability of such resources, potentially compromising grid resilience. Offshore wind farms (OWFs) are increasingly considered as viable alternatives for black start support. Nevertheless, their inherent variability and intermittent …

A Theoretical Model for a Fermi–Boson Hybrid Particle in Nuclear and Particle Physics
Abstract: We present a theoretical model for a Fermi–Boson Hybrid Particle (FBHP) that unifies fermionic half-integer spin matter fields with bosonic integer-spin force fields within a single quantum framework. By extending conventional quantum field theory, a hybrid creation operator is formulated that combines fermionic and bosonic operators through a continuous mixing parameter, allowing smooth interpolation between Fermi–Dirac and Bose–Einstein statistical behaviour. A generalized statistical mechanics formalism is developed, leading to quantitative …

FDTD-based Time Domain Analysis of CMOS Gate Driven Interconnects
Abstract: Accurate time domain analysis of CMOS gate driven interconnects is important for the design and analysis of high performance VLSI systems. Conventionally, CMOS driver is approximated as a constant resistance instead of non-linear and time-varying MOS resistance, which causes inaccurate modeling of CMOS driver. This paper presents a new method for FDTD-based transient analysis of CMOS gate driven interconnect line using a generalized model. The generalized model of CMOS inverter …
