We present a simple motorized rotation mount for half-wave plate that can be used to rapidly change the polarization of light. use device switch high power laser beam between different optical dipole traps in an ultracold atom experiment. The uses stepper motor with hollow shaft, which allows propagate along axis minimizing inertia and mechanical complexity. A machined adapter is wave plate. ch...

This paper introduces a new automatic tetrahedral mesh generator on the adaptive finite element ALBERTA code. The procedure can be applied to 3D domains with boundary surfaces which are projectable on faces of a cube. The generalization of the mesh generator for complex domains which can be split into cubes or hexahedra is straightforward. The domain surfaces must be given as analytical or disc...

Consider a graph G with |V (G)| = p and |E(G)| q let f : V (G) → {k, k + 1, 2, . − 1}} be an injective function. The induced edge labeling ∗ for vertex is defined by (e) all e uv ∈ E(G) bijective. If f(V (G)) ∪ {f E(G)} , 1}, then called k-super cube root mean labeling. such exists, graph. In this paper, I introduce prove the existence of to graphs viz., triangular snake Tn, double D(Tn), Quadr...

BACKGROUND Several reference axes are used to establish femoral rotational alignment during total knee arthroplasty, but debate continues with regard to which axis is most accurately and easily identified during surgery. Computer-assisted navigation systems have been developed in an attempt to more accurately and consistently align implants during total knee arthroplasty, but it is unknown if n...

of the Thesis DCT Based SPIHT Architecture for Hyperspectral Image Data Compression by Jieming Xu Master of Science in Electrical and Computer Engineering Northeastern University, August 2016 Prof. Vinay K. Ingle, Adviser The wavelet transformation is leading and widely used technology in transform coding. Many coding algorithms are designed for this transformation based on its unique structure...

The paper introduces the methods with time-resolved technique and isosurface display technique to get twoand three-dimensional (3D) acoustical imaging for scanning acoustic microscopy. Time-resolved technique presents the way to realize two-dimensional (2D) acoustical imaging – A(O-), Band C-scan, and a discrete combinatorial 3D image; and isosurface display technique realizes a 3D image with c...

In this paper we show that graphs of “neighbourly” cubical complexes – cubical complexes in which every pair of vertices spans a (unique) cube – have good expansion properties, using a technique based on multicommodity flows. By showing that graphs of stable set polytopes are graphs of neighbourly cubical complexes we give a new proof that graphs of stable set polytopes have edge expansion 1.

We prove that for d > 1 the information rate of the perfect secret sharing scheme based on the edge set of the d-dimensional cube is exactly 2/d. Using the technique developed, we also prove that the information rate of the infinite d-dimensional lattice is 1/d.
