COMPLETELY RANDOMIZED DESIGN OF A MARKETING EXPERIMENT [PDF]

Annals of the University of Petrosani: Economics, 2018
The marketing experiment is a deliberate, "challenged", simulated small-scale, and relatively artificial, marketing phenomenon to highlight how its evolution is influenced by one or more causal factors.

Stable Inverse Reinforcement Learning: Policies From Control Lyapunov Landscapes

IEEE Open Journal of Control Systems
Learning from expert demonstrations to flexibly program an autonomous system with complex behaviors or to predict an agent's behavior is a powerful tool, especially in collaborative control settings.

Sum-of-squares proofs and the quest toward optimal algorithms [PDF]

, 2014
In order to obtain the best-known guarantees, algorithms are traditionally tailored to the particular problem we want to solve. Two recent developments, the Unique Games Conjecture (UGC) and the Sum-of-Squares (SOS) method, surprisingly suggest that this

Stability Analysis of Nonlinear Time–Delayed Systems with Application to Biological Models

International Journal of Applied Mathematics and Computer Science, 2017
In this paper, we analyse the local stability of a gene-regulatory network and immunotherapy for cancer modelled as nonlinear time-delay systems. A numerically generated kernel, using the sum-of-squares decomposition of multivariate polynomials, is used ...

Cyclotomic equations and square properties in rings

International Journal of Mathematics and Mathematical Sciences, 1986
If R is a ring, the structure of the projective special linear group PSL2(R) is used to investigate the existence of sum of square properties holding in R.

SUMS OF SQUARES FROM ELLIPTIC PFAFFIANS [PDF]

International Journal of Number Theory, 2008
We give a new proof of Milne's formulas for the number of representations of an integer as a sum of 4m2and 4m(m + 1) squares. The proof is based on explicit evaluation of pfaffians with elliptic function entries, and relates Milne's formulas to Schur Q-polynomials and to correlation functions for continuous dual Hahn polynomials.

Sums of Squares on Hypersurfaces

Results in Mathematics
We show that the Pythagoras number of rings of type $\mathbb{R}[x,y, \sqrt{f(x,y)}]$ is infinite, provided that the polynomial $f(x,y)$ satisfies some mild conditions.

On the rational function field of real curves without real points

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
Let F be the field of rational functions of a real algebraic curve without real points. It is well-known that in F we can express -1 as a sum of two squares. We show that -1 is also a sum of four fourth powers, six sixth powers, and so on.
