An instance of the two-dimensional strip packing problem is specified by n rectangular items, each having a width, 0 < wn ≤ 1, and height, 0 < hn ≤ 1. The objective is to place these items into a strip of width 1, without rotations, such that they are nonoverlapping and the total height of the resulting packing is minimized. In this thesis, we consider the version of the twodimensional strip pa...

The one-dimensional bearing estimation problem of linearly periodic arrays with sensor position errors has been tackled by the Toeplitz approximation method (TAM), iterative TAM, modified TAM, and iterative MTAM without calibrating the sensor positions. This paper extends these methods to the twodimensional situation using a uniform planar array with sensor position errors to estimate the 2-D a...

This paper proposes a function approximation scheme based on Voronoi diagram, a technique of computational geometry, toward optimization cost saving in real engineering applications. The scheme consists of a blending function of local information over spatial structure among sample points that is topologically represented with Voronoi diagram, an estimation method of function gradients through ...

This paper introduces a new tabu search algorithm for a twodimensional (2D) Strip Packing Problem (2D-SPP). It integrates several key features: A direct representation of the problem, a satisfaction-based solving scheme, two different complementary neighborhoods, a diversification mechanism and a particular tabu structure. The representation allows inexpensive basic operations. The solving sche...

Modern generations of field-programmable gate arrays (FPGAs) allow for partial reconfiguration. In an online context, where the sequence of modules to be loaded on the FPGA is unknown beforehand, repeated insertion and deletion of modules leads to progressive fragmentation of the available space, making defragmentation an important issue. We address this problem by propose an online and an offl...

The new examples are found of the constraints which link the 1+2dimensional and multifield integrable equations and lattices. The vector and matrix generalizations of the Nonlinear Schrödinger equation and the Ablowitz-Ladik lattice are considered among the other multifield models. It is demonstrated that using of the symmetries belonging to the hierarchies of these equations leads, in particul...

The Corpus Christi Ship Channel in Texas connects the Port of to Gulf Mexico. is seeking deepen channel allow fully loaded very large crude carriers access proposed terminals within port complex. Dredge material from deepening be used as beach nourishment and create offshore berms along Mustang Island San Jose Island. fate was assessed using Hybrid C-X (COSMOSXBeach) Sediment Budget Model.

In this paper we present a statistical model with a nonsymmetric half-plane (NSHP) region of support for twodimensional continuous-valued vector fields. It has the simplicity, efficiency, and ease of use of the well-known hidden Markov model (HMM) and associated Baum-Welch algorithms for time-series and other one-dimensional problems. At the same time, it is able to learn textures on a twodimen...
