In this paper we investigate Isotropic Multiresolution Analysis(IMRA), isotropic refinable functions, and wavelets. The main results are the characterization of IMRAs in terms of the Lax-Wiener Theorem, and the characterization of isotropic refinable functions in terms of the support of their Fourier transform. As an immediate consequence of these results,(More)
—Recent research has created a significant interest [18], [19] in the design and development of a new global-scale communication network that can overcome the limitations of the current Internet. Among the many directions for improving networking technology, recent pursuit to design better flow control has led to the emergence of explicit congestion control(More)
Spinal deformity and paraplegia/quadriplegia are the most common complications of tuberculosis (TB) of spine. TB of dorsal spine almost always produces kyphosis while cervical and lumbar spine shows reversal of lordosis to begin with followed by kyphosis. kyphosis continues to increase in adults when patients are treated nonoperatively or by surgical(More)
Spinal tuberculosis (TB) produces neurological complications and grotesque spinal deformity, which in children increases even with treatment and after achieving healing. Long-standing, severe deformity leads to painful costo-pelvic impingement, respiratory distress, risk of developing late-onset paraplegia and consequent reduction in quality and longevity(More)
The monovision concept of correcting one eye for distance and the other for near may be utilized in presbyopes undergoing refractive surgery. We have performed a systematic review of published literature to evaluate the factors influencing monovision success, and to determine the visual outcome in patients with monovision. Articles in MEDLINE and published(More)
Laser epithelial keratomileusis (LASEK) is a surgical technique that may be performed in patients with low myopia who are considering conventional photorefractive keratectomy (PRK), in patients with thin corneas, and in patients with professions or lifestyles that predispose them to trauma. Ethanol (18%) is applied for 25 seconds and a hinged epithelial(More)
— In this paper, we propose Layered TCP (LTCP for short), a simple layering technique for the congestion window response of TCP to make it more scalable in highspeed, high RTT networks. LTCP is a two dimensional congestion control framework-the macroscopic control uses the concept of layering to quickly and efficiently make use of the available bandwidth(More)
The location and extent of white matter lesions on magnetic resonance imaging (MRI) are important criteria for diagnosis, follow-up and prognosis of multiple sclerosis (MS). Clinical trials have shown that quantitative values, such as lesion volumes, are meaningful in MS prognosis. Manual lesion delineation for the segmentation of lesions is, however,(More)
In this paper we present a set of 3D-rigid motion invariant texture features. We experimentally establish that when they are combined with mean attenuation intensity differences the new augmented features are capable of discriminating normal from abnormal liver tissue in arterial phase contrast enhanced X-ray CT–scans with high sensitivity and specificity.(More)
