Local Fractional Metric Dimensions of Rotationally Symmetric and Planar Networks

open access: yesIEEE Access, 2020
Mathematical modeling, coding or labeling with the help of numeric numbers based on the parameter of distance plays a vital role in the studies of the structural properties of the networks such as accessibility, centrality, clustering, complexity ...

Minimum Weight Resolving Sets of Grid Graphs [PDF]

open access: yes, 2014
For a simple graph $G=(V,E)$ and for a pair of vertices $u,v \in V$, we say that a vertex $w \in V$ resolves $u$ and $v$ if the shortest path from $w$ to $u$ is of a different length than the shortest path from $w$ to $v$. A set of vertices ${R \subseteq

Spatial-temporal fractions verification for high-resolution ensemble forecasts [PDF]

open access: yes, 2013
Experiments with two ensemble systems of the resolutions of 10 km (MF10km) and 2 km (MF2km) were designed to examine the value of cloud-resolving ensemble forecast in predicting small spatiotemporal-scale precipitation.

Variable neighbourhood search for resolving routing and wavelength assignment problem in optical wavelength-division multiplexing networks

open access: yesIET Communications, 2011
The issue of finding optimal signal routes is one of the main challenges within the framework of optimal networks. This study aims at illustrating the development of a new, mixed-integer mathematical model for solving the static routing and wavelength assignment (RWA) problem in optical wavelength-division multiplexing (WDM) networks and presents the ...

Stabbing line segments with disks: complexity and approximation algorithms [PDF]

open access: yes, 2017
Computational complexity and approximation algorithms are reported for a problem of stabbing a set of straight line segments with the least cardinality set of disks of fixed radii $r>0$ where the set of segments forms a straight line drawing $G=(V,E)$ of

Community-driven sanitation improvement in deprived urban neighbourhoods: meeting the challenges of local collective action, co-production, affordability and a trans-sectoral approach. [PDF]

open access: yes, 2013
There is an international consensus that urban sanitary conditions are in great need of improvement, but sharp disagreement over how this improvement should be pursued.

A targeted public: public services in fifteenth-century Ghent and Bruges [PDF]

open access: yes, 2010
Though the phrase 'public services' is a nineteenth-century invention, which was supported by a developed rhetoric of political economy, this article shows that the concept, practice and supply of such services could also be found in the medieval city ...

Housing professionalism in the United Kingdom: the final curtain or a new age? [PDF]

open access: yes, 2002
The unusually large, predominantly municipal, housing sector in the UK has provided the context for a large occupational grouping of "housing managers" that has claimed professional status.

Resolutions of p-stratifolds with isolated singularities

open access: yes, 2003
Recently M. Kreck introduced a class of stratified spaces called p-stratifolds [M. Kreck, Stratifolds, Preprint]. He defined and investigated resolutions of p-stratifolds analogously to resolutions of algebraic varieties.
