This paper examines the optimal control of CO2 emissions from a perspective of efficiency analysis. Several centralized data envelopment analysis (DEA) models are introduced to study the optimal allocation of CO2 emissions under spatial, temporal and spatial–temporal allocation strategies,...

This paper examines the effect of size control policy on the energy and carbon efficiency for Chinese fossil fuel power industry. For this purpose, we propose two non-radial directional distance functions for energy/carbon efficiency analysis of fossil fuel electricity generation. One is named a...

Thermal and field perturbations away from the renormalization-group fixed point are considered in 2D conformal field theory. General expressions for the effective critical exponents ν, α and δ are obtained in terms of the central charge, third moment of energy and spin correlation,...

An expression of the XXZ model is given from which the Ising, isotropic XY and Heisenberg models may be more properly obtained by varying only one anisotropy parameter. The ground state and spin configuration of the antiferromagnetic quasi-classical s = 12XXZ chain in a magnetic field of...

This paper presents future scenarios of Irish energy-related CO2 emissions to 2020, using a combination of multi-sectoral decomposition analysis with scenario analysis. Alternative development paths, driving forces and sectoral contributions in different scenarios have been explored. The...
