Adaptive Quantum Heat Engines [PDF]
arXiv, 2021 For heat engines working between two heat baths, functionality is often conditioned on a set of fixed constraints such as given internal structure of the engine and given temperatures for the baths. It is, however, important to devise heat engines which can function adaptively, in particular when the engine is a quantum system and the baths are subject

1.4 W Passively Q-Switched Mode-Locked Tm:CALGO Laser with a MoS2 Saturable Absorber
PhotonicsThe passively Q-switched mode-locked (QML) operation of a Tm:CaGdAlO4 (Tm:CALGO) bulk laser pumped by a wavelength-tunable Ti:sapphire oscillator using molybdenum disulfide (MoS2) as a saturable absorber was demonstrated.

On efficient iterative schemes for finding all solutions of non-linear engineering problems [PDF]
Computational Algorithms and Numerical DimensionsNonlinear equations are important in engineering because they may simulate complicated real-world phenomena such as fluid dynamics, material stress, and electrical circuits, where linear assumptions fail.

Specific Features of Solid Fuels Combustion in Oxygen Atmosphere with Recirculation of CO2
Eurasian Chemico-Technological Journal, 2015 Aspects of coal combustion have been experimentally studied under oxyfuel conditions, one of the promising technologies for carbon capture and storage (CCS). Here, the thermogravimetric analysis (TGA) method was chosen as an experimental technique.

SimJEB: Simulated Jet Engine Bracket Dataset [PDF]
, 2021 This paper introduces the Simulated Jet Engine Bracket Dataset (SimJEB): a new, public collection of crowdsourced mechanical brackets and accompanying structural simulations. SimJEB is applicable to a wide range of geometry processing tasks; the complexity of the shapes in SimJEB offer a challenge to automated geometry cleaning and meshing, while ...

Harnessing energy extracted from heat engines to charge quantum batteries [PDF]
arXiv, 2023 We explore the performance of three- and two-stroke heat engines with a qutrit working substance in charging two-level quantum batteries. We first classify the heat engines into two groups depending on their working methods. The first type of heat engine, the sequential engine, evolves through three distinct strokes, viz., heat, work, and cold strokes.
