A Study of the Minimum Thermal Power of a Nuclear Reactor
Journal of Nuclear Engineering, 2021 The minimum mass for a critical reactor is well studied whereas the minimum heat production from a nuclear reactor has received little attention. The thermal power of a (sub)critical reactor originates from fission as well as radioactive decay.

The Power of Scale for Parameter-Efficient Prompt Tuning [PDF]
Conference on Empirical Methods in Natural Language Processing, 2021 In this work, we explore “prompt tuning,” a simple yet effective mechanism for learning “soft prompts” to condition frozen language models to perform specific downstream tasks.

A Double-Bed Adsorptive Heat Transformer for Upgrading Ambient Heat: Design and First Tests
Energies, 2019 A full scale lab prototype of an adsorptive heat transformer (AHT), consisting of two adsorbers, an evaporator, and a condenser, was designed and tested in subsequent cycles of heat upgrading.

Energies, 2022 In this work, chemical recycling as an alternative to conventional end-of-life treatments was studied. Two different types of end-of-life tires (ELT), truck tires and mix tires (50:50 mixture of passenger car and truck tires), were pyrolyzed in a batch ...

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 The electric propulsion drives for the more-electric aircraft need lightweight and high-efficiency power converters. Moreover, a modular approach to the construction of the drive ensures reduced costs, reliability, and ease of maintenance.

Active magnetocaloric heat pipes provide enhanced specific power of caloric refrigeration
Communications Physics, 2020 Today almost all refrigeration systems are based on compressors, which often require harmful refrigerants and typically reach 50% of the Carnot efficiency. Caloric cooling systems do not need any detrimental fluids and are expected to reach 60–70% of the

Energies, 2023 The voltage in distribution systems is controlled by the under-load tap changer of the substation and the pole transformer of the primary feeders. Recently, as one of the main countermeasures, a step voltage regulator is being introduced to solve voltage

Opportunities for and challenges to further reductions in the “specific power” rating of wind turbines installed in the United States [PDF]
, 2021 A wind turbine’s “specific power” rating relates its capacity to the swept area of its rotor in terms of Watt per square meter. For a given generator capacity, specific power declines as rotor size increases.
