We are interested in the problem of guarding simple orthogonal polygons with the minimum number of r-guards. The interior point p belongs an orthogonal polygon P is visible from r-guard g, if the minimum area rectangle contained p and q lies within P . A set of point guards in polygon P is named guard set (as denoted G) if the union of visibility areas of these point guards be equal to polygon ...

A hidden guard set G is a set of point guards in polygon P that all points of the polygon are visible from some guards in G under the constraint that no two guards may see each other. In this paper, we consider the problem for finding minimum hidden guard sets in histogram polygons under orthogonal visibility. Two points p and q are orthogonally visible if the orthogonal bounding rectangle for ...

Orthogonal metric space is a considerable generalization of usual obtained by establishing perpendicular relation on set. Very recently, the notions orthogonality set and are described notable fixed point theorems given in orthogonal spaces. Some for generalizations contraction principle via altering distance functions spaces presented proved this paper. Furthermore, an example to clarify these...

In this paper, a method for parameterizing orthogonal wavelet transforms is presented. The parameter space is given by the rotation angles of the orthogonal 2 2 rotations used in the lattice filters realizing the stages of the wavelet transform. Different properties of orthogonal wavelet transforms can be expressed in this parameter space. Then, the parameter space is restricted to the set of r...

This paper examines optical CDMA (OCDMA) communication techniques with optical orthogonal codes. These optical orthogonal codes (OOC) set are constructed by using difference set methods. Simulations that show OOC reduce interference due to other users and channel noise. Probability of error can be reduce by selection of proper weight (w), length (n) & cardinality(C) of OOC.

In this paper, a novel method for constructing complementary sequence set with zero correlation zone (ZCZ) is presented by interleaving and combining three orthogonal matrices. The constructed set can be divided into multiple sequence groups and each sequence group can be further divided into multiple sequence subgroups. In addition to ZCZ properties of sequences from the same sequence subgroup...

Orthogonal Array Testing is one of the most important techniques that produce test cases which are much lesser in number than black box testing, but are more relevant. In spite of its importance, the technique has not been explored as much as other techniques. The present work, therefore, explores the literature to find the gaps in the literature and hence propose a new technique based on Genet...
