We propose a convex variational approach to space-time reconstruction which estimates surface normal information and integrates it into the photoconsistency estimation as well as into an anisotropic spatio-temporal total variation regularization. As such the proposed method generalizes the works [4], [5]. Although [4] already studied anisotropic regularization they did not estimate normals but ...

This paper discusses the effects of MOSFET threshold voltage variations on the reliability of nanometer-scale CMOS logic gates. The reliability is quantified in terms of the probability-of-failure of individual CMOS gates, which is obtained from extensive Monte Carlo simulations of these gates. The study considers different nano-scale CMOS technology generations and compares the effect of thres...

A frequency bandgap is a range of wave frequencies that are prohibited from passing through a medium. The dispersion relation, which links the frequency to the wave number, enables us to illustrate the bandgaps. In [E. H. Lee, “A survey of variational methods for elastic wave propagation analysis in composites with periodic structures,” in Dynamics of Composite Materials, E. H. Lee, ed., ASME, ...

We present an overview of the Density Matrix Renormalization Group and its connections to Quantum Groups, Matrix Products and Conformal Field Theory. We emphasize some common formal structures in all these theories. We also propose two-dimensional extensions of the variational matrix product ansatzs.

In this paper, one-dimensional (1-D) fast 8 8 inverse integer transform algorithm for Windows Media Video 9 (WMV-9/VC-1) is proposed. Based on the symmetric property of the integer transform matrix and the matrix operations, which denote the row/column permutations and the matrix decompositions, the efficient fast 1-D 8 8 inverse integer transform is developed. Therefore, the computational comp...

In this paper we are presenting the theory of balance equations of the Continuum Thermodynamics (balance systems) in a geometrical form using Poincare-Cartan formalism of the Multisymplectic Field Theory. A constitutive relation C of a balance system BC is realized as a mapping between a (partial) 1-jet bundle of the configurational bundle π : Y → X and the extended dual bundle similar to the L...

Title Labeling of data-driven cell complexes for surface reconstruction Abstract This thesis introduces a new flexible framework for surface reconstruction from acquired point sets. This framework casts the surface reconstruction problem as a cells binary labeling problem on a point-guided cell complex under a combination of visibility constraints. This problem can be solved by computing a simp...

Recently, variational Bayesian (VB) techniques have been applied to probabilistic matrix factorization and shown to perform very well in experiments. In this paper, we theoretically elucidate properties of the VB matrix factorization (VBMF) method. Through finite-sample analysis of the VBMF estimator, we show that two types of shrinkage factors exist in the VBMF estimator: the positive-part Jam...

Against to the different regions of membership functions indicated image in the traditional image segmentation variational model, resulting segmentation is not clear, de-noising effect is not obvious problems, this paper proposes multi-target model for image segmentation and the splitting algorithm. The model uses a sparse regularization method to maintain the boundaries of segmented regions, t...
