Centered Cubic Lattice Method Comparison
The Centered Cubic Lattice method is used for an iso-surface extraction. This paper focuses on its comparison with other fundamental methods (Marching Cubes, Marching Tetrahedra) that are also used to extract an iso-surface from regular volume data. Iso-surfaces that are generated using above mentioned methods and mathematical data are compared due to area and volume approximation. The Hausdorf...

متن کاملPlanar Force-Constant Method for Lattice Dynamics of Cubic III-Nitrides
Using the density-functional theory within the Full Potential Linear Augmented PlaneWave (FP-LAPW) method, we have calculated, in this work, the equation of state, the e ective charges and the phonon dispersion along [100] and [111] directions for the cubic III-Nitrides(c-BN, c-AlN, c-GaN and c-InN), including hydrostatic strains dependence. A good agreement with the micro-Raman scattering expe...
متن کاملA Note on Projecting the Cubic Lattice
The theorem is at first surprising, since A has ( n+1 2 ) degrees of freedom, whereas v has only n degrees of freedom (for the explanation see the remark following the proof of Theorem 2). The problem arises from a question in communication theory (see §5), which calls for projections Λv with high packing density. Since both the determinant and minimal norm of a lattice are continuous functions...
متن کاملA Preliminary Note on the Absorption of 'Makaradhwaja' (Sulphide of Mercury)
a great hold on the minds of the people in India that many practitioners of Western medicine also use it. There is probably something of real value about it, as it has resisted the ravages of time for many centuries and is universally esteemed to the present day. Preparation of ' makaradhwaja ?It is necessary at the outset to outline the process of preparation of this drug, as according to the ...
