Methodologies for Systematic Evaluation and Targeted Mitigation of Deficiencies in Critical Machine Learning Models
Despite the growing use of machine learning in healthcare, critical challenges remain unaddressed, models often fail to respond appropriately to life-threatening conditions, exhibit poor generalizability in real-world clinical settings, and show unequal performance across patient subgroups. These …

Optimizing Reservoir Computing Architecture for Dynamic Spectrum Sensing Applications
… Ratio (SNR). Leveraging Liquid State Machines (LSMs), which emulate spiking neural networks like the ones in the human brain, prove to be highly effective for real-time data monitoring for such temporal tasks. The inherent advantages of LSM-based recurrent neural networks, such as low …

Forward Modeling for Bolometry and Disruption Mitigation in Tokamaks or How to Kill Your Plasma With Confidence, Style, and Pizzazz
… by plasma disruption events, which can damage critical machine components. Disruption damage can be mitigated by high-Z impurities, delivered by Massive Gas Injection (MGI) or Shattered Pellet Injection (SPI). Impurities radiate energy out of the plasma and onto the first wall. Evenly …

On-line Dynamic Security Assessment in Power Systems.
… This allowed to identify the single machine equivalent (SIME) method as the potentially fastest assessment method and, hence, well suited for on-line DSA. Means for further performance improvement of the SIME method are investigated such as the reduction of the degree of system model …

POWER SYSTEM TRANSIENT STABILITY CONTROL WITH CONSIDERATION OF UNCERTAINTIES
… power flow (OPF) calculation, which utilizes the critical machine (CM) theory in the Extended Equal Area Criteria (EEAC). A detailed composite load model is later applied to capture a more accurate dynamic behaviour of the system. Secondly, a preventive-emergency coordinated control method is …

An integrated approach incorporating dynamic and static security limits in optimum power dispatch
… regard to the necessary security requirements. A critical review of the current practices of security and optimization in power system operation shows that they are essential elements in Energy Management System computer softwares. Since optimality and security present conflicting requirements on …

A Practical Method for Power Systems Transient Stability and Security
… for transient stability analysis of multi machine power systems. The proposed method calculates the potential and kinetic energies for all machines in a power system and then compares the largest group of kinetic energies to the smallest groups of potential energies. A decision based on the …
