Operational adequacy studies of a PV-based & energy storage stand-alone microgrid

, 2015
This paper presents a probabilistic approach in the modeling of stand-alone microgrids to predict their operational adequacy performance considering uncertainty of energy storage system (ESS), photovoltaic system (PVS) and conventional generator (CG ...

Multiyear and multi-criteria AC Transmission Expansion Planning model considering reliability and investment costs [PDF]

, 2016
One of the major concerns in Power Systems is surely related with their reliability. Long-term expansion planning studies traditionally use the well-known deterministic "N-1" contingency criterion.

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

Journal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

Do deepfakes, digital replicas and human digital twins justify personality rights?

The Journal of World Intellectual Property, EarlyView.
Abstract Unauthorised deepfakes are deeply problematic, from the spreading of misinformation to non‐consensual pornographic content. This paper asks whether deepfakes, digital replicas and human digital twins justify personality rights. To address this question, it examines the harms that deepfakes can cause through disinformation, demeaning content ...

Spinning reserve estimation in microgrids

, 2012
Spinning reserve (SR) is an important resource which can safeguard power systems without involuntary load shedding. Increasing the SR requirement can reduce the probability and severity of loss of load. However providing SR has a cost.
