Agribusiness, EarlyView.ABSTRACT Strategic positioning becomes increasingly important as markets mature, particularly in consumer‐facing industries that offer similar products, experiential cues, and values‐based messages. This study offers a conceptual model to examine the strategic positioning factors that motivate consumers to visit one local business over another before ...

Basis for high order divergence-free finite element spaces
Results in Applied MathematicsA method classically used in the lower polynomial degree for the construction of a finite element basis of the space of divergence-free functions is here extended to any polynomial degree for a bounded domain without topological restrictions.

AIChE Journal, EarlyView.ABSTRACT Conceptual process design combines discrete configuration choices with continuous operating decisions, often yielding difficult mixed‐integer nonlinear or simulation‐based optimization problems. This work presents an exploratory computational assessment of Ising‐based solvers, simulated annealing, quantum annealing, and entropy computing, as ...

The Proper Basis for Polynomial Ideals [PDF]
We define a new type of ideal basis called the proper basis that improves both Gröbner basis and Buchberger\u27s algorithm. Let $x_1$ be the least variable of a monomial ordering in a polynomial ring $K[x_1,\dotsc,x_n]$ over a field $K$.

AIChE Journal, EarlyView.Abstract Thermophilic anaerobic digestion (AD) is an attractive process due to its higher biogas yield compared to mesophilic digestion. To mitigate its higher heating demand and potential process instability, a dual‐layer control architecture comprising a decision‐making layer and an adaptive model predictive control (MPC) system is proposed.

A basis for a quotient of symmetric polynomials
, 2019 149 pages. Working document containing most of what I have proven so far on these quotients. Rough at the edges and elsewhere too. Will eventually be split into two articles and polished for submission. Posted here for citing. The title is outdated (there are three bases now and much more) but has been preserved to not break old backreferences. v3 adds

A basis for the Y1 subspace of diagonal harmonic polynomials
Discrete Mathematics, 1998 AbstractThe space DHn of Sn diagonal harmonics is the collection of polynomials P(x, y) = P(x1,…,xn,y1,…,yn) which satisfy the differential equations ∑i=1n ∂xir∂yis, P(x, y) = 0 for all r,s ⩾ 0 (with r + s > 0). Computer explorations by Haiman have revealed that DHn has a number of remarkable combinatorial properties.
