Glued Near Polygons

open access: yesEuropean Journal of Combinatorics, 2001
A partial linear space \((P,L)\) \((P\) set points, \(L\) set of lines) is called a near polygon if the diameter of its point graph is finite and if for every pair \((p,l)\in P\times L\) there is a unique point \(q\in P\) on \(l\) nearest to \(p\) with respect to the natural distance defined on the graph.

Combinatorial Construction of Some Near Polygons

open access: yesJournal of Combinatorial Theory, Series A, 1997
A near \(2n\)-gon is a linear incidence system \((P,L)\) satisfying: (i) every line contains at least two points, (ii) the point graph of \((P,L)\) is connected with diameter \(n\), (iii) for each point line pair \((p,l)\), there is a unique point \(q\) on \(l\) nearest \(p\). Note that near 4-gon is the same thing as a generalized quadrangle.

3D MODELING OF HISTORICAL DOGER CARAVANSARIES BY DIGITAL PHOTOGRAMMETRY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Caravansaries are sort of bigger khan that established on the busy trade roads to provide any kind of supplies but essentially all Caravansaries on Anatolia are established for caravans' accommodations which are passing through on caravan rout.

The Regular Near Polygons of Order (s, 2) [PDF]

open access: yesJournal of Algebraic Combinatorics, 2004
A near polygon is a partial linear space \({\mathcal S}=({\mathcal P},{\mathcal L})\) with the property that for every point \(p\in {\mathcal P}\) and for every line \(L\in {\mathcal L}\) there exists a unique point on \(L\) nearest to \(p\). Here distances \(d\) are measured in the collinearity graph \(\Gamma\). If \(n=\text{ diam}(\Gamma)\), then \({\

Numerical analysis to estimate near-wellbore drilling induced failures area for fractured formation using Universal Discrete Element Codes (UDEC)

open access: yesCogent Engineering, 2021
There have been reported cases of wellbore instability near-wellbore area due to failures associated with drilling operations, the magnitude and extension of the failure area is imprecisely evaluated by copious researchers due to some of the limitations ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.
