Multivariate Boundaries of a Self Representing Stratum of Large Units in Agricultural Survey Design
Survey Research Methods, 2012 In business surveys in general, and in multipurpose agricultural surveys in particular, the problem of designing a sample from a list frame usually consists of two different aspects.

THE ANALYSIS OF IMAGES OF A CIRCULAR SOURCE IN N-POINT GRAVITATIONAL LENSES
Odessa Astronomical Publications, 2018 Currently, in the field of computer processing, there are difficulties. When processing astrophysical experimental data, the difficulties are connected, on the one hand, with a large amount of information that requires processing, and, on the other hand,

q-Differential equations for q-classical polynomials and q-Jacobi-Stirling numbers [PDF]
, 2016 We introduce, characterise and provide a combinatorial interpretation for the so-called q-Jacobi–Stirling numbers. This study is motivated by their key role in the (reciprocal) expansion of any power of a second order q-differential operator having the

Group field theories for all loop quantum gravity
New Journal of Physics, 2015 Group field theories represent a second quantized reformulation of the loop quantum gravity state space and a completion of the spin foam formalism. States of the canonical theory, in the traditional continuum setting, have support on graphs of arbitrary

Discrete Analysis, 2023 Limits of Latin squares, Discrete Analysis 2023:8, 66 pp. There has been a great deal of work over the last fifteen to twenty years on the theme of continuous limits of discrete combinatorial objects. In particular, any sequence of graphs of increasing

From Nash Equilibria to Chain Recurrent Sets: An Algorithmic Solution Concept for Game Theory
Entropy, 2018 In 1950, Nash proposed a natural equilibrium solution concept for games hence called Nash equilibrium, and proved that all finite games have at least one.

Larger Corner-Free Sets from Better NOF Exactly-$N$ Protocols
Discrete Analysis, 2021 Larger corner-free sets from better NOF exactly-$N$ protocols, Discrete Analysis 2021:19, 9 pp. If $G$ is an Abelian group, then a _corner_ in $G^2$ is a subset of the form $\{(x,y),(x+d,y),(x,y+d)\}$ with $d\ne 0$.

A fast approximation algorithm for solving the complete set packing problem
, 2014 We study the complete set packing problem (CSPP) where the family of feasible subsets may include all possible combinations of objects. This setting arises in applications such as combinatorial auctions (for selecting optimal bids) and cooperative game ...

Strict group testing and the set basis problem
, 2014 Group testing is the problem to identify up to d defectives out of n elements, by testing subsets for the presence of defectives. Let t(n,d,s) be the optimal number of tests needed by an s-stage strategy in the strict group testing model where the ...

Recovering General Relativity from a Planck Scale Discrete Theory of Quantum Gravity
Philosophy of PhysicsAn argument is presented that if a theory of quantum gravity is physically discrete at the Planck scale and the theory recovers General Relativity as an approximation, then, at the current stage of our knowledge, causal sets must arise within the theory,
