Partitioning and separating sets of orthogonal polygons
Information Sciences, 1987A geometrical object in the plane is said to be orthogonal if its edges are either vertical or horizontal. A polygon is called orthoconvex if for every vertical-or-horizontal segment, its two endpoints lying in the polygon implies the whole segment lying in the polygon.

A Lattice-Partition Framework of Downlink Non-Orthogonal Multiple Access Without SIC
IEEE Transactions on Communications, 2018In this paper, a novel lattice-partition-based downlink non-orthogonal multiple access framework is proposed. This framework is motivated by recognizing the algebraic structure behind the previous scheme recently proposed by Shieh and Huang as a lattice ...

Scheduling parallel implementations of partitioned orthogonal transformations
SPIE Proceedings, 1992Orthogonal matrix transformations form an important part of matrix-based signal processing applications. Systolic arrays for computing these algorithms have been developed and the size of these arrays usually depends directly on the size of the problem.

Set-partition methods and orthogonal designs
2010 IEEE International Symposium on Information Theory, 2010Space-time block codes based on orthogonal designs are useful from practical point of view as these codes admit symbol-by-symbol maximum-likelihood decoding and also achieve full diversity. Though the square orthogonal designs have been studied quite extensively, there is very little progress in the area of non-square orthogonal designs.

Partitioning Orthogonal Histograms into Rectangular Boxes
2018The problem of partitioning an orthogonal polyhedron into a minimum number of boxes was shown to be NP-hard in 1991, but no approximability result is known except for a 4-approximation algorithm for 3D-histograms. In this paper we broaden the understanding of the 3D-histogram partitioning problem.

New partitioning schemes for parallel modified Gram-Schmidt orthogonalization
Proceedings of the 1997 International Symposium on Parallel Architectures, Algorithms and Networks (I-SPAN'97), 2002In this paper we are concerned with parallel implementation of row-oriented Gram-Schmidt orthogonalization. For the data partitioning four types of columnwise partitioning schemes were considered: column (1-col), block, cyclic and block-cyclic (b-c) partitioning.

Approximate partitioning of 2D objects into orthogonally convex components
Computer Vision and Image Understanding, 2013A fast and efficient algorithm to obtain an orthogonally convex decomposition of a digital object is presented. The algorithm reports a sub-optimal solution and runs in O(nlogn) time for a hole-free object whose boundary consists of n pixels. The decomposition algorithm can, in fact, be applied on any hole-free orthogonal polygon; in our work, it is ...

Computer simulation of the partitioning by mutually orthogonal lines
2019 IEEE 15th International Conference on the Experience of Designing and Application of CAD Systems (CADSM), 2019The partitioning problem of areas into regions along mutually orthogonal lines is considered. A mathematical model of the problem has been proposed, taking into account economic, agrotechnical and fire prevention restrictions. A method has been developed for obtaining a local-optimal partition of a given region based on the construction of two ...
