Convex model predictive control for collision avoidance

IET Control Theory & Applications, 2021
This manuscript proposes a model predictive control for collision avoidance for the regulation problem of deterministic linear systems, which provides a priori guarantees of strong system theoretic properties, such as positive invariance and asymptotic ...

Cylindrical Algebraic Sub-Decompositions [PDF]

, 2014
Cylindrical algebraic decompositions (CADs) are a key tool in real algebraic geometry, used primarily for eliminating quantifiers over the reals and studying semi-algebraic sets.

Robotic sensor based on score and accuracy values in q-rung complex diophatine neutrosophic normal set with an aggregation operation

Alexandria Engineering Journal, 2023
The multiple-attribute decision-making (MADM) problem is resolved through the q-rung complex diophantine neutrosophic normal set (q-rung CDNNS). An important way to express uncertain information is using q-rung orthopair fuzzy sets (q-ROFs).

New MCDM Algorithms with Linear Diophantine Fuzzy Soft TOPSIS, VIKOR and Aggregation Operators

Mathematics, 2022
In this paper, we focus on several ideas associated with linear Diophantine fuzzy soft sets (LDFSSs) along with its algebraic structure. We provide operations on LDFSSs and their specific features, elaborating them with real-world examples and ...

Fixed points of the EM algorithm and nonnegative rank boundaries [PDF]

, 2015
Mixtures of $r$ independent distributions for two discrete random variables can be represented by matrices of nonnegative rank $r$. Likelihood inference for the model of such joint distributions leads to problems in real algebraic geometry that are ...

Algebraic Expression and Construction of Control Sets of Graphs Using Semi-Tensor Product of Matrices

IEEE Access, 2019
Using a new matrix analysis tool, called semi-tensor product of matrices (STP) developed in recent years, this paper investigates the problem of finding control sets (or dominating sets) of graphs mathematically.

Adapting Real Quantifier Elimination Methods for Conflict Set Computation [PDF]

, 2015
The satisfiability problem in real closed fields is decidable. In the context of satisfiability modulo theories, the problem restricted to conjunctive sets of literals, that is, sets of polynomial constraints, is of particular importance.

Robot sensors process based on generalized Fermatean normal different aggregation operators framework

AIMS Mathematics, 2023
Novel methods for multiple attribute decision-making problems are presented in this paper using Type-Ⅱ Fermatean normal numbers. Type-Ⅱ Fermatean fuzzy sets are developed by further generalizing Fermatean fuzzy sets and neutrosophic sets.
