Small bipartite subgraph polytopes [PDF]

open access: yes, 2010
We compute a complete linear description of the bipartite subgraph polytope, for up to seven nodes, and a conjectured complete description for eight nodes.

Extremal bipartite independence number and balanced coloring [PDF]

open access: yes, 2023
In this paper, we establish a couple of results on extremal problems in bipartite graphs. Firstly, we show that every sufficiently large bipartite graph with average degree $D$ and with $n$ vertices on each side has a balanced independent set containing $

Design of Multiband Balanced Folded Dipole Antenna Based on a Dual-Arm Structure for Mobile Handsets [PDF]

open access: yes, 2008
YesIn this paper, a balanced antenna for mobile handset applications with enhanced bandwidth performance, that covers four bands (GSM1800, GSM1900, UMTS and 2.4-GHz WLAN), is investigated.

Biholes in balanced bipartite graphs [PDF]

open access: yes, 2023
A bihole in a bipartite graph $G$ with partite sets $A$ and $B$ is an independent set $I$ in $G$ with $|I\cap A|=|I\cap B|$. We prove lower bounds on the largest order of biholes in balanced bipartite graphs subject to conditions involving the vertex ...

An expression for land surface water storage monitoring using a two-formation geological weighing lysimeter [PDF]

open access: yes, 2007
Field studies have demonstrated that ground surface rainfall accumulation can be detected at depth by synchronous increases in static confined groundwater pore pressures.

Optimal chemical balance weighing designs for $v+1$ objects [PDF]

open access: yes, 2003
summary:The paper studies the estimation problem of individual weights of objects using a chemical balance weighing design under the restriction on the number times in which each object is weighed.

A-optimal biased spring balance weighing design [PDF]

open access: yes, 2011
summary:In this paper we study the problem of estimation of individual measurements of objects in a biased spring balance weighing design under assumption that the errors are uncorrelated and they have different variances.

Optimum chemical balance weighing design with diagonal matrix of errors based on balanced block designs

open access: yes, 2004
The paper is studying the estimation problem of individual weights of objects using the chemical balance weighing design under the restriction on the number of times in which each object is weighed.

On the bipartite independence number of a balanced bipartite graph [PDF]

open access: yes, 1993
The bipartite independence number αBIP of a bipartite graph G is the maximum order of a balanced independent set of G. Let δ be the minimum degree of the graph.

Resolvable balanced bipartite designs [PDF]

open access: yes, 1976
A block B denotes a set of k = k1 + k2 elements which are divided into two subsets, B1 and B2, where ∣Bi∣ = ki, i = 1 or 2. Two elements are said to be linked in B if and only if they belong to different subsets of B.
