From the point of view of quality management, it is an important issue to reduce the transmission time in the network. The quickest path problem is to 6nd the path in the network to send a given amount of data from the source to the sink such that the transmission time is minimized. Traditionally, this problem assumed that the capacity of each arc in the network is deterministic. However, the c...

In this work, we report about our recent results concerning the fabrication of Long Period Grating (LPG) sensors in several optical fibers, through the Electric Arc Discharge (EAD) technique. In particular, the following silica fibers with both different dopants and geometrical structures are considered: standard Ge-doped, photosensitive B/Ge codoped, P-doped, pure-silica core with F-doped clad...

V aluing the Arc (VTA) was a research programme that ran from 2007 to 2012 and mapped, modelled and valued ecosystem services within and flowing from the Eastern Arc Mountains, with the objective of informing decisions for sustainable management of the remaining natural habitats. The services we focused on were carbon, water, nature-based tourism, timber and non-timber forest products (charcoal...

The intention of this note is to motivate the researchers to study Hadwiger’s conjecture for circular arc graphs. Let η(G) denote the largest clique minor of a graph G, and let χ(G) denote its chromatic number. Hadwiger’s conjecture states that η(G) ≥ χ(G) and is one of the most important and difficult open problems in graph theory. From the point of view of researchers who are sceptical of the...

In this paper, we propose a geometrical compensation algorithm for multiview image captured by an arc multi-camera array. To capture multiview image or multiview video, we require more than two cameras arranged on a multicamera array. This multi-camera array, however, has geometrical errors since it is manually built. These errors are related to the mismatch in the vertical and horizontal direc...

Abstract The atmospheric deposition of nitrate and ammonia species has been identified as a major factor in the decline of water quality in the Chesapeake Bay. Recent reports have indicated that atmospheric deposition may account for 25 to 80% of the total nitrogen load entering the Bay. However, many uncertainties exist regarding the accuracy of these estimates including the accuracy of the at...

Absrrucr: Applying Gauss-Seidel approach to the improvements of two simultaneous methods for finding polynomial zeros, presented in [9], two iterative methods with faster convergence are obtained. The lower bounds of the R-order of convergence for the accelerated methods are given. The improved methods and their accelerated modifications arc discussed in view of the convergence order and the nu...

The non-linear effects that have been observed in adaptive filtering scenarios arc explained from the point of view of the structure that underlies the desired data. While the model structure used by the conventional adaptive filter is a linear combination of lapped-dclay line signals, that adaptive filter model does not generally correspond to the structure that best describes the desired data...

Most primal minimum cost network flow (MCNF) algorithms can be seen as variants on cancelling negative augmenting cycles. The analogous view of dual MCNF algorithms is that they cancel positive augmenting cuts. In a companion paper we show that if a dual algorithm chooses to cancel cuts which have the greatest rate of increase in dual objective value per arc, which are called maximum mean cuts,...

Various guidelines for the protection of human beings against possible adverse effects resulting from exposure to electromagnetic fields (EMFs) have been published with a view towards continual improvement; therefore, decreasing exposure is an important research area. The aim of this study was to investigate the possibility of decreasing electric field exposure with arc flash rated personal pro...
