Exploring the impacts of China’s water resource tax policies: A trade-off between economic development and ecological protection

open access: yesFrontiers in Environmental Science, 2022
The reform of water resource tax policies is an important measure in the process of China’s green economic transformation. Therefore, improving the accuracy of tax policy impact prediction is crucial for policymakers to make correct decisions. This study

Products of effective topological spaces and a uniformly computable Tychonoff Theorem [PDF]

open access: yesLogical Methods in Computer Science, 2013
This article is a fundamental study in computable analysis. In the framework of Type-2 effectivity, TTE, we investigate computability aspects on finite and infinite products of effective topological spaces.

Complexity theory for spaces of integrable functions [PDF]

open access: yesLogical Methods in Computer Science, 2017
This paper investigates second-order representations in the sense of Kawamura and Cook for spaces of integrable functions that regularly show up in analysis. It builds upon prior work about the space of continuous functions on the unit interval: Kawamura

Realistic computable error bounds for three dimensional finite element analyses in linear elasticity [PDF]

open access: yes, 2011
We obtain a computable estimator for the energy norm of the error in piecewise affine and piecewise quadratic finite element approximations of linear elasticity in three dimensions.

Effective zero-dimensionality for computable metric spaces [PDF]

open access: yesLogical Methods in Computer Science, 2015
We begin to study classical dimension theory from the computable analysis (TTE) point of view. For computable metric spaces, several effectivisations of zero-dimensionality are shown to be equivalent.

More Reservoirs or Transfers? A Computable General Equilibrium Analysis of Projected Water Shortages in the Arkansas River Basin

open access: yesJournal of Agricultural and Resource Economics, 2000
A computable general equilibrium model of the southeastern Colorado economy is used to compare the economic impacts of a proposed increase in reservoir storage to an alternative: temporary water transfers.

Linked Metadata for FAIR Digital Objects Carrying Computable Knowledge [PDF]

open access: yesResearch Ideas and Outcomes, 2022
Introduction To advance the goals of the Mobilizing Computable Biomedical Knowledge (MCBK) Movement, we are exploring the use of FAIR Digital Objects (FDOs) (De Smedt et al. 2020, Williams et al. 2021).First, we are beginning to clarify the full range of

Feynman Meets Turing: Computability Aspects of Exact Circuit Synthesis, Gate Efficiency, and the Spectral Gap Conjecture

open access: yesIEEE Transactions on Quantum Engineering
We consider exact quantum circuit synthesis, quantum gate efficiency, and the spectral gap conjecture from the perspective of computable analysis. Circuit synthesis, in both its exact and its approximate variant, is fundamental to the circuit model of ...
