, 2012 Theory construction is a process, i.e., a set of state changes by an autonomous agent, or by an organism composed of several autonomous agents. In the first case, we may recall the approach of Pierce (1931) that considers three logical operations (inference rules) on a knowledge base, i.e., a set of propositions asserted to be valid: abduction ...

Constructal view of scaling laws of river basins [PDF]
, 2006 River basins are examples of naturally organized flow architectures whose scaling properties have been noticed long ago. Based on data of geometric characteristics, Horton [Horton, R.E., 1932. Drainage basin characteristics. EOS Trans. AGU 13, 350–361.],

Constructive matrix theory [PDF]
Journal of High Energy Physics, 2007 We extend the technique of constructive expansions to compute the connected functions of matrix models in a uniform way as the size of the matrix increases. This provides the main missing ingredient for a non-perturbative construction of the $ ^{\star 4}_4$ field theory on the Moyal four dimensional space.

Improving Thermal Performance of Rectangular Microchannel Heat Sinks using Porous Layer: CFD Simulation and Optimization [PDF]
Journal of Applied Fluid Mechanics, 2023 Microchannel heat sinks are very widely used due to their high heat transfer coefficients and low refrigerant requirements. Nevertheless, microchannel heat sinks still perform sub-optimally when it comes to thermal performance.

Constructive Theory of Ordinals
, 2023 In Chapter 3 of his Notes on constructive mathematics, Martin-L{ö}f describes recursively constructed ordinals. He gives a constructively acceptable version of Kleene's computable ordinals. In fact, the Turing definition of computable functions is not needed from a constructive point of view. We give in this paper a constructive theory of ordinals that
