Nearly constant acceleration model for state estimation in the range‐Doppler plane

IET Radar, Sonar & Navigation, 2021
The problem of motion modelling in the range‐Doppler (R‐D) plane as well as range and Doppler estimation for the Cartesian nearly constant acceleration motion, which is a common manoeuvering motion, is investigated.

A Novel MILP Model Based on the Topology of a Network Graph for Process Planning in an Intelligent Manufacturing System

Engineering, 2021
Intelligent process planning (PP) is one of the most important components in an intelligent manufacturing system and acts as a bridge between product designing and practical manufacturing.

Application of morphing technique with mesh-merging in rapid hull form generation

International Journal of Naval Architecture and Ocean Engineering, 2012
Morphing is a geometric interpolation technique that is often used by the animation industry to transform one form into another seemingly seamlessly. It does this by producing a large number of ‘intermediate’ forms between the two ‘extreme’ or ‘parent ...

Static spectra and static families of Fredholm-type operators under tensor product

Arab Journal of Basic and Applied Sciences
In this study, we introduce the static spectrum, the Weyl static families, the upper semi-Fredholm static families, and the Browder static families. These families consist of bounded linear operators parameterized by a scalar variable.

Optimal designs for testing the functional form of a regression via nonparametric estimation techniques [PDF]

, 2000
For the problem of checking linearity in a heteroscedastic nonparametric regression model under a fixed design assumption we study maximin designs which maximize the minimum power of a nonparametric test over a broad class of alternatives from the ...

A study on input noise second-order filtering and smoothing of linear stochastic discrete systems with packet dropouts

Advances in Difference Equations, 2020
We investigate non-Gaussian noise second-order filtering and fixed-order smoothing problems for non-Gaussian stochastic discrete systems with packet dropouts.

SUBSPACE ARRANGEMENTS DEFINED BY PRODUCTS OF LINEAR FORMS [PDF]

Journal of the London Mathematical Society, 2005
We consider the vanishing ideal of an arrangement of linear subspaces in a vector space and investigate when this ideal can be generated by products of linear forms. We introduce a combinatorial construction (blocker duality) which yields such generators in cases with a lot of combinatorial structure, and we present the examples that motivated our work.

Natural operations on holomorphic forms [PDF]

, 2018
summary:We prove that the only natural differential operations between holomorphic forms on a complex manifold are those obtained using linear combinations, the exterior product and the exterior differential.

Products of linear forms and Tutte polynomials

European Journal of Combinatorics, 2010
Let Δbe a finite sequence of n vectors from a vector space over any field. We consider the subspace of \operatorname{Sym}(V) spanned by \prod_{v \in S} v, where S is a subsequence of Δ. A result of Orlik and Terao provides a doubly indexed direct sum of this space. The main theorem is that the resulting Hilbert series is the Tutte polynomial evaluation
