Carbon Balance and Management, 2018 Background Biomass models are useful for several purposes, especially for quantifying carbon stocks and dynamics in forests. Selecting appropriate equations from a fitted model is a process which can involves several criteria, some widely used and others

Dynamic Modeling and Simulation of Robot Manipulators: The Newton-Euler Formulation [PDF]
, 2011 Dynamic modeling means deriving equations that explicitly describes the relationship between force and motion in a system. To be able to control a robot manipulator as required by its operation, it is important to consider the dynamic model in design of ...

An ultraweak formulation of the Kirchhoff-Love plate bending model and DPG approximation [PDF]
arXiv, 2018 We develop and analyze an ultraweak variational formulation for a variant of the Kirchhoff-Love plate bending model. Based on this formulation, we introduce a discretization of the discontinuous Petrov-Galerkin type with optimal test functions (DPG). We prove well-posedness of the ultraweak formulation and quasi-optimal convergence of the DPG scheme ...

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow
Advanced Functional Materials, EarlyView.Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

Journal of High Energy PhysicsThe mathematical consistency of the BMHV scheme of dimensional regularisation (DReg) comes at the cost of requiring symmetry-restoring counterterms to cancel the regularisation-induced breaking of gauge and BRST invariance.

An optimisation model for minimising changes in frequency allocations
EURO Journal on Computational Optimization, 2022 In this paper we deal with a problem associated with frequency assignment. Suppose we have a number of transmitters, each of which has been allocated a frequency.

Frontiers in Applied Mathematics and Statistics, 2018 This paper deals with fast simulations of the hemodynamics in large arteries by considering a reduced model of the associated fluid-structure interaction problem, which in turn allows an additional reduction in terms of the numerical discretisation.

Computer assisted modelling of linear, integer and separable programming problems [PDF]
, 1984 For mathematical programming (MP) to have greater impact upon the decision making process, MP software systems must offer suitable support in terms of model communication and modelling techniques .

Fractional and fractal extensions of epidemiological models [PDF]
arXivOne way to study the spread of disease is through mathematical models. The most successful models compartmentalize the host population according to their infectious stage, e.g., susceptible (S), infected (I), exposed (E), and recovered (R). The composition of these compartments leads to the SI, SIS, SIR, and SEIR models. In this Chapter, we present and
