(p,k)-coloring problems in line graphs
2005
Theoretical Computer Science
Finally, upper bounds on the optimal values are derived in general graphs by sequential algorithms based on Welsh-Powell and Matula orderings. ...
We also give complexity results for the problem of finding a maximum (p, k)-colorable subgraph in line graphs. ...
As a consequence of some of these results, for a perfect graph G and for p and k fixed, one can recognize in polynomial time whether G ∈ K p S k . ...

Performance Metrics of Wormhole Detection using Path Tracing Algorithm
2015
Indian Journal of Science and Technology
Methods: We propose path tracing algorithm for detection of worm hole attack as a extension of aodv protocols the path of the node effectively computes the per hop distance of its neighbor node with per ...
The main aim of the paper is to protect the network from worm hole attack using path tracing algorithm with the advancement of aodv and compare the performance parameters. ...
Every Hop Distance Estimation The vicinity of wormhole can be recognized by computing the separation between each one bounce in a way We consider Round Excursion Time (RTT) worth to figure the every jump ...

recognize a large amount of homologous points on a set of images in a completely automatic way. ...
The modeling and the three-dimensional reconstruction of objects, structures or sites of interest assume an important role in the field of cultural heritage. ...
The large number of points extracted by the SIFT operator, can produce a huge number of tie-points on the images; such circumstance could make hard the bundle block adjustment process. ...

This system captures images of the tables in which marks are written by the teacher in the students" answer book, recognize the numbers or marks from it and fill the same in appropriate database on the ...
This is very time consuming and tedious job. In this paper an attempt is made to automatically recognize numbers in the document by capturing images of that document. ...
But if the data is available in the form of hard copy or handwritten form then it is very time consuming and tedious job to convert the data available in hard format to soft format. ...

A Survey on Graph Drawing Beyond Planarity
[article]
2018
arXiv
pre-print
Aim of this survey is to describe the main research directions in this area, the most prominent known results, and some of the most challenging open problems. ...
Graph Drawing Beyond Planarity is a rapidly growing research area that classifies and studies geometric representations of non-planar graphs in terms of forbidden crossing configurations. ...
Recognizing straight-line RAC drawable graphs is NP-hard in general [23] , while it can be solved in linear time for complete bipartite graphs [106] . ...

Vanity fair
2008
Proceeding of the 17th ACM conference on Information and knowledge mining - CIKM '08
Second, we demonstrate analytical vulnerabilities based on the ability to separate the queries in a bundle into threads corresponding to individual users. ...
We show that these propensities interact badly with two forms of vulnerabilities in the bundling scheme. ...
As shown in Table 6 , about 3% of the bundles have a user that issued at least half of the queries in the bundle. ...

Native Build System for Unity Builds with Sophisticated Bundle Strategies
2021
IEICE transactions on information and systems
However, the longer build times of recent large C++ projects have imposed a requirement on build systems: i.e., unity builds. ...
To accomplish this goal, our build system uses sophisticated bundle strategies developed on the basis of hints extracted from the preprocessed code of each source file. ...

1-Fan-bundle-planar drawings of graphs
2018
Theoretical Computer Science
In particular, we restrict the bundling to the end segments of the edges. Similarly to 1-planarity, we call our model 1-fan-bundle-planarity, as we allow at most one crossing per bundle. ...
To enable the comparison with other established near-planarity models in graph drawing, we formulate a new edge-bundling model which is inspired by the recently introduced fan-planar graphs. ...
We glue the baby snakes together at their cutvertices. By Lemma 11, we only have to check whether the legs are big, which can be done in linear time. ...
