ACETAZOLEAMIDE (Diamox) has been used to lower temporarily the intraocular pressure in eyes with raised tension (Becker, 1954; Agarwal and Saxena, 1955), in restoring flat chambers after intra-ocular operations (Murphy, 1954; Thrope, 1955a; Agarwal, Sharma, and Malik, 1955), as a pre-operative measure in cataract surgery to diminish the incidence of complications, and to complete the operation ...

The rapid growth in mobile communication users necessitates the development of reliable communication systems that provide higher data rates. Tomeet these requirements, techniques such as multiple input multiple output (MIMO) and orthogonal frequency division multiplexing (OFDM) have been developed in recent years. Current research activity is focused on developing MIMO-OFDM systems that combin...

In this paper we give a general, robust, and efficient approach for numerical solutions of partial differential equations (PDEs) arising in image processing and computer vision. The well-established variational computational techniques, namely, finite element, finite volume, and complementary volume methods, are introduced on a common base to solve nonlinear problems in image multiscale analysi...

Partial differential equation (PDE)–based image processing has played a substantial role and become more popular in the recent years. In the application of weld defect detection, the PDE models can be applied for image smoothing and segmentation. In this study, anisotropic diffusion proposed by Perona Malik known as Perona Malik Anisotropic Diffusion (PMAD) model is used as a denoising process ...

Grouping by graph partitioning is an effective engine for perceptual organization. This graph partitioning process, mainly motivated by computational efficiency considerations, is usually implemented as recursive bi-partitioning, where at each step the graph is broken into two parts based on a partitioning measure. We study four such measures, namely, the minimum cut [11], average cut [6], Shi-...
