Label Distribution Learning

open access: yes, 2016
Although multi-label learning can deal with many problems with label ambiguity, it does not fit some real applications well where the overall distribution of the importance of the labels matters.

Thermographic non-destructive evaluation for natural fiber-reinforced composite laminates [PDF]

open access: yes, 2018
Natural fibers, including mineral and plant fibers, are increasingly used for polymer composite materials due to their low environmental impact. In this paper, thermographic non-destructive inspection techniques were used to evaluate and characterize ...

Design and Performance Analysis of a Thermal Energy Storage System With Steam Extraction and Electric Heating in a Coal‐Fired Power Plant

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To alleviate the impact of the instability of renewable energy power generation on the power grid, coal‐fired power plants (CFPPs) have to undertake peak shaving tasks, which puts forward high requirements for the flexibility of CFPPs. To enhance the flexibility of CFPPs to consume more renewable energy, this paper innovatively proposes a ...

On Soliton Automorphisms in Massive and Conformal Theories [PDF]

open access: yes, 1998
For massive and conformal quantum field theories in 1+1 dimensions with a global gauge group we consider soliton automorphisms, viz. automorphisms of the quasilocal algebra which act like two different global symmetry transformations on the left and ...

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling

Design and Optimization of a Novel Kalina‐Organic Rankine Cycle System Based on LNG Cold Energy Utilization

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a novel integrated system (SDKC‐DORC) that combines a split‐flow dual‐pressure Kalina cycle with a secondary organic Rankine cycle for the synergistic utilization of solar energy and liquefied natural gas (LNG) cold energy.

Accuracy of some useful closure relations in combination with the reference interaction site model theory for fluids of single component diatomic molecules

open access: yesAIP Advances, 2022
We examined the accuracy of the reference interaction site model theory in terms of the thermodynamics of fluids consisting of single-component diatomic molecules, where we evaluated the internal energy, pressure, and isothermal compressibility.
