Category of quantizations and inverse problem
We introduce a category composed of all quantizations of all Poisson algebras. By the category, we can treat in a unified way the various quantizations for all Poisson algebras and develop a new classical limit formulation.

Modeling Groundwater Flow in Heterogeneous Porous Media with YAGMod
Modeling flow and transport in porous media requires the management of complexities related both to physical processes and to subsurface heterogeneity. A thorough approach needs a great number of spatially-distributed phenomenological parameters, which ...

Application of direct and inverse kinematics and dynamics in motion planning of manipulator links
For the synthesis of manipulators and robots, an accurate analysis of the movements of the individual links is essential. This thesis deals with motion planning of the effector of a multi-linked manipulator.

Spectral, Scattering and Dynamics: Gelfand–Levitan–Marchenko–Krein Equations
In this paper, we consider the Gelfand–Levitan–Marchenko–Krein approach. It is used for solving a variety of inverse problems, like inverse scattering or inverse problems for wave-type equations in both spectral and dynamic formulations.

Inverse Problems Have Inverse Complexity [PDF]
In this paper we show that inverting problems of higher complexity is easier than inverting problems of lower complexity. While inverting Σp i3CNFSAT is known to be coNP-complete sideri for i=1 we prove that it remains coNP-complete for i=2 and is in P for all i⩾ 3. Relatedly, we show that inverting Σp i3DNFSAT is in P for all i⩾ 1.

On the inverse Collatz-Sinogowitz irregularity problem
The Collatz-Sinogowitz irregularity index is the oldest known numerical measure of graph irregularity. For a simple and connected graph GG of order nn and size mm, it is defined as CS(G)=λ1−2m/n,\hspace{0.1em}\text{CS}\hspace{0.1em}\left(G)={\lambda }_{1}

Uniqueness of semilinear elliptic inverse problem
We consider the uniqueness of the inverse problem for a semilinear elliptic differential equation with Dirichlet condition. The necessary and sufficient condition of unique solution is obtained.
