On the Length of a Random Minimum Spanning Tree [PDF]

Combinatorics, Probability and Computing, 2015
We study the expected value of the lengthLnof the minimum spanning tree of the complete graphKnwhen each edgeeis given an independent uniform [0, 1] edge weight. We sharpen the result of Frieze [6] that limn→∞$\mathbb{E}$(Ln) = ζ(3) and show that$$ \mathbb{E}(L_n)=\zeta(3)+\frac{c_1}{n}+\frac{c_2+o(1)}{n^{4/3}}, $$wherec1,c2are explicitly defined ...

Use of Span Lengths Extracted from the HVI Fibrogram to Predict Yarn Quality

Journal of Natural Fibers, 2023
Cotton fiber properties play a significant role in determining the quality of yarns and fabrics. Information on fiber length distribution is crucial throughout many textile processing steps to transform fibers into yarn.

A Note on Random Minimum Length Spanning Trees [PDF]

The Electronic Journal of Combinatorics, 2000
Consider a connected $r$-regular $n$-vertex graph $G$ with random independent edge lengths, each uniformly distributed on $[0,1]$. Let $mst(G)$ be the expected length of a minimum spanning tree. We show in this paper that if $G$ is sufficiently highly edge connected then the expected length of a minimum spanning tree is $\sim {n\over r}\zeta(3)$. If we

Span Length Effects on the Progressive Collapse Behaviour in Concrete Structures [PDF]

Journal of Stress Analysis, 2018
Progressive and general collapse of structures are extremely able to cause great casualties and financial losses. Accordingly, evaluation the performance of structures after losing primary elements is of great importance to prevent the structural ...

Determining the factors affecting the gestational length in sheep [PDF]

Archives Animal Breeding, 2021
This research aimed to determine the effects of body weight, the body condition score (BCS), body measurements, birth type (single offspring or twin birth), birth weight and sex on the gestational length in sheep (n=111).

Analysis of Limb segment length to the total body height among the undergraduate students in a medical college of Nepal

Asian Journal of Medical Sciences, 2020
Background: Total body height is important for calculating body mass index, drug dosages calculations and other patient care issues. Total height estimation from different body measurements are surrogate measures of stature which is very useful when only

The decay of the refocused Hahn echo in double electron–electron resonance (DEER) experiments [PDF]

Magnetic Resonance, 2021
Double electron–electron resonance (DEER) is a pulse electron paramagnetic resonance (EPR) technique that measures distances between paramagnetic centres. It utilizes a four-pulse sequence based on the refocused Hahn spin echo.

Long-term studies of mesosphere and lower-thermosphere summer length definitions based on mean zonal wind features observed for more than one solar cycle at middle and high latitudes in the Northern Hemisphere [PDF]

Annales Geophysicae, 2022
Specular meteor radars (SMRs) and partial reflection radars (PRRs) have been observing mesospheric winds for more than a solar cycle over Germany (∼ 54∘ N) and northern Norway (∼ 69∘ N).

On the total length of the random minimal directed spanning tree [PDF]

Advances in Applied Probability, 2006
In Bhatt and Roy's minimal directed spanning tree construction for a random, partially ordered set of points in the unit square, all edges must respect the ‘coordinatewise’ partial order and there must be a directed path from each vertex to a minimal element. We study the asymptotic behaviour of the total length of this graph with power-weighted edges.
