Semi-Empirical Models and Revision of Predicting Approaches of Tree Aboveground Biomass Assessments
biomass allometry a and B scalar coefficients independent physical and biological parameterization wood specific gravity form factors checking the consistency of biomass equations
2023/12/4
Tree aboveground biomass (e.g., bole, branches, and foliage), M, plays key roles in forest management as it is the basis for evaluating the sink and flux of, for example, carbon and nitrogen, stand pr...
IMPROVING UNDERWATER ACCURACY BY EMPIRICAL WEIGHTING OF IMAGE OBSERVATIONS
underwater photogrammetry, image quality, bundle adjustment, image observation weighting
2018/6/4
An underwater imaging system with camera and lens behind a flat port does not behave as a standard pinhole camera with additional parameters. Indeed, whenever the entrance pupil of the lens is not in ...
Adaptive k-tree sample plot for the estimation of stem density: An empirical approach
plotless sampling distance sampling bias efficiency forest sampling
2018/3/6
Available budgets for the inventory of non-commercial woodlands are small. Therefore, there has been increased
interest in using distance methods, such as k-tree sampling, which are faster than fixed...
City Networks of Online Commodity Services in China: Empirical Analysis of Tmall Clothing and Electronic Retailers
city networks online commodity services intercity relationships specialization
2018/4/3
City networks have been a critical topic in the fields of urban geography and regional economics. Numerous studies have explored city networks, focusing mainly on infrastructure and industrial network...
How Chinese Financial Centers Integrate into Global Financial Center Networks: An Empirical Study Based on Overseas Expansion of Chinese Financial Service Firms
urban networks corporate networks financial service firms global financial centers China
2018/4/3
The increasing globalization of the Chinese economy has been enabled by both Chinese financial institutions operating globally as well as international firms operating within China. In geographical te...
Criteria of Empirical Significance:A Success Story
empirical significance cognitive significance testability meaningfulness empirical content definition measurement falsifiability verifiability aboutness supervenience empirical equivalence realism structural realism antirealism
2016/6/14
The sheer multitude of criteria of empirical significance has been taken as evidence that the pre-analytic notion being explicated is too vague to be useful. I show instead that a significant number o...
Empirical Adequacy in the Received View
empirical adequacy Received View Constructive Empiricism embedding empirical substructure appearances observations
2016/6/14
I show that the central notion of Constructive Empiricism, empirical adequacy, can be expressed syntactically and specifically in the Received View of the logical empiricists. The formalization shows ...
Symmetry,empirical equivalence,and identity
symmetries empirical equivalence identity of physical states redundancy
2016/6/13
The paper proposes a novel approach to the much discussed question of which symmetries have direct empirical significance and which do not. The approach is based on a development of a recently propose...
Against the Empirical Viability of the Deutsch Wallace Approach to Quantum Mechanics
Everett interpretation quantum mechanics
2016/6/12
The subjective Everettian approach to quantum mechanics presented by Deutsch and Wallace fails to constitute an empirically viable theory of quantum phenomena. The decision theoretic implementation of...
Artificial Examples of Empirical Equivalence
Empirical equivalence underdetermination van Fraassen conventionality of geometry systems of the world
2016/6/12
In this paper I analyze three artificial examples of empirical equivalence: van Fraassen’s alternative formulations of Newton’s theory, the Poincaré-Reichenbach argument for the conventionality of geo...
On the Empirical Equivalence Between Special Relativity and Lorentz's Ether Theory
relativity Einstein Lorentz empirical equivalence empirical evidence non-empirical virtues
2016/6/12
In this paper I argue that the case of Einstein’s special relativity vs. Hendrik Lorentz’s ether theory can be decided in terms of empirical evidence, in spite of the predictive equivalence between th...
Another Look at Empirical Equivalence and Underdetermination of Theory Choice
Empirical equivalence underdetermination theory choice non-empirical virtues empirical evidence confirmation special relativity Hendrik Lorentz
2016/6/12
In 1991 Larry Laudan and Jarret Leplin proposed a solution for the problem of predictive equivalence and empirical underdetermination. In this paper we claim that, even though Laudan and Leplin’s reas...
Emergent spacetime and empirical (in) coherence
spacetime quantum gravity empirical incoherence causal set theory loop quantum gravity string theory non-commutative geometry
2016/5/30
Numerous approaches to a quantum theory of gravity posit fundamental ontologies that exclude spacetime, either partially or wholly. This situation raises deep questions about how such theories could r...
Within philosophy of physics it is broadly accepted that presentism as an empirical hypothesis has been falsified by the development of special relativity. In this paper, I identify and reject an assu...
Measuring Empirical Computational Complexity
trend-prof empirical computational complexity
2016/5/24
The standard language for describing the asymptotic behavior of algorithms is theoretical computational complexity. We propose a method for describing the asymptotic behavior of programs in practice b...
