This paper presents the design and analysis of an areaefficient programmable processing element (PPE) for implementing diverse cryptographic systems and diverse bitwidths (currently 16, 32, and 64). To evaluate the effectiveness of our design, we implement π-Cipher and BMW on the PPE. π-Cipher is a new algorithm for authenticated encryption that offers advantages over AES-GCM and is a candidate...

The Bacillus subtilis RNase M5 complex, responsible for the terminal maturation of 5 S rRNA, includes two proteins. One of these proteins is ribosomal protein BL16 (equivalent to Escherichia coli EL18); the other, the alpha component, is required for catalysis. The RNase M5 alpha component has been purified in bulk extensively, and the active polypeptide (Mr approximately 24,000) identified fol...

We introduce a meshless finite element framework for solving light transport problems. Traditional finite element methods use basis functions parameterized directly on the mesh surface. The creation of suitable parameterizations or clusterings requires pre-processing that is difficult, error-prone, and sensitive to the quality of input geometry. The resulting light transport solutions still ten...

Denda and Marante [1] have developed the boundary element method for the mixed mode fracture analysis of multiple curvilinear cracks in the general anisotropic solids in two dimensions for which in-plane Mode I, II, and out-of-plane Mode III, of fracture are coupled. They have developed the crack tip singular element (CTSE) to model any curvilinear cracks, including center and edge cracks. The ...

In disease-associated genes, the understanding of the functional significance of deep intronic nucleotide variants may represent a difficult challenge. We have previously reported a new disease-causing mechanism that involves an intronic splicing processing element (ISPE) in ATM, composed of adjacent consensus 5' and 3' splice sites. A GTAA deletion within ISPE maintains potential adjacent spli...

AbstructEfficient implementation of morphological operations requires the decomposition of structuring elements into the dilation of smaller structuring elements. Zhuang and Haralick presented a search algorithm to find optimal decompositions of structuring elements in binary morphology. In this paper, we use the concepts of Top of a set and Umbra of a surface to extend this algorithm to find a...

This is to certify that I have examined this copy of master's thesis by Vikram Malik and have found that it is complete and satisfactory in all respects, and that any and all revisions required by the final examining committee have been made.Acknowledgements First and foremost, I would like to thank my advisor Dr Carolyn Crouch, for her support and guidance for the last two years. She was patie...

A coherent processor is presented which is capable of performing a large class of 1-D linear space-variant operations. The only components of the processor are a 1-D input, a mask whose transmittance is specified by the desired linear operation, and an output plane. Compared with other 1-D processors, this processor has advantages of real space compactness and total elimination of vignetting. E...

In the last few years, the graphics processor units (GPUs) have moved away from the traditional fixed-function 3D graphics pipeline toward a flexible general-purpose computational engine. Moreover they are getting cheaper and more powerful [1]. The GPU is especially well-suited to address problems that can be expressed as data-parallel computations i.e. the same program is executed on many data...

In this paper, we introduce a new family of mixed finite element spaces of higher order (k ≥ 1) on general quadrilateral grids. A typical element has two fewer degrees of freedom than the well-known RaviartThomas finite element RT[k], yet enjoys an optimal-order approximation for the velocity in L 2-norm. The order of approximation in the divergence norm is one less than the velocity, as is com...
