Metal complexes of anxiolitic drugs. X-Ray crystal structure and electronic properties of aquobromazepam(oxalato O1 O2) copper(II)

1987

The crystal structure of the title compound has been determined from single-crystal x-ray diffraction data. The copper(II) ion is surrounded by two nitrogen atoms of the bromazepam** molecule [N(imine) and N(pyridine)], and two oxygen atoms of the oxalate ion in a square planar arrangement. One molecule of water is linked to the copper(II) ion in the axial position. The complex has been also characterized by electronic, e.s.r. and i.r. spectra.

Photo-switching spin pairs—synergy between LIESST effect and magnetic interaction in an iron(ii) binuclear spin-crossover compound

2001

The decrease of the magnetic response under irradiation at very low temperature was interpreted as a new evidence of synergy between magnetic interaction and spin transition in an iron(II) binuclear SC compound. Real Cabezos, Jose Antonio, Jose.A.Real@uv.es

Constructive procedures to solve 2-dimensional bin packing problems with irregular pieces and guillotine cuts

2015

Abstract This paper presents an approach for solving a new real problem in cutting and packing. At its core is an innovative mixed integer programme model that places irregular pieces and defines guillotine cuts. The two-dimensional irregular shape bin packing problem with guillotine constraints arises in the glass cutting industry, for example, the cutting of glass for conservatories. Almost all cutting and packing problems that include guillotine cuts deal with rectangles only, where all cuts are orthogonal to the edges of the stock sheet and a maximum of two angles of rotation are permitted. The literature tackling packing problems with irregular shapes largely focuses on strip packing i…

Error bounds for a convexity-preserving interpolation and its limit function

2008

AbstractError bounds between a nonlinear interpolation and the limit function of its associated subdivision scheme are estimated. The bounds can be evaluated without recursive subdivision. We show that this interpolation is convexity preserving, as its associated subdivision scheme. Finally, some numerical experiments are presented.

The Reconstruction of Polyominoes from Approximately Orthogonal Projections

2001

The reconstruction of discrete two-dimensional pictures from their projection is one of the central problems in the areas of medical diagnostics, computer-aided tomography, pattern recognition, image processing, and data compression. In this note, we determine the computational complexity of the problem of reconstruction of polyominoes from their approximately orthogonal projections. We will prove that it is NP-complete if we reconstruct polyominoes, horizontal convex polyominoes and vertical convex polyominoes. Moreover we will give the polynomial algorithm for the reconstruction of hv-convex polyominoes that has time complexity O(m3n3).
