Most research on wireless sensor networks has focused on homogeneous networks where all nodes have identical transmission ranges. However, heterogeneous networks, where nodes have different transmission ranges, are potentially much more efficient. In this chapter, we study how heterogeneous networks can be configured by distributed self-organization(More)
BACKGROUND Little is known about survival on peritoneal dialysis (PD) in Indian patients since the initiation of continuous ambulatory PD (CAPD) in India in 1991. Survival data from single centers with small numbers have been published. OBJECTIVE A retrospective 4-center analysis for predictors of survival >3 years in south Indian chronic PD patients. (More)
The proposed system is a portable camera based visual assistance prototype for bind people to identify currency notes and also helps them to read printable texts from the handheld objects. To read printable texts, an efficient algorithm that combines an Optical Character Recognition (OCR) with Hierarchical optimization is used. In Pattern Recognition OCR(More)
This paper discusses about advanced disk storage necessary for distributed systems. It briefly discusses the disk storage research and the various storage systems developed. Among them the Petal, distributed virtual disks developed at the systems research center, Digital Equipment Corporation and PersonalRaid, mobile storage for distributed and disconnected(More)
The sustained growth in VLSI technology is fuelled by the continued shrinking of transistor to ever smaller dimension. The benefits of miniaturization are high packing densities, high circuit speed and low power dissipation. Binary multiplier is an electronic circuit used in digital electronics such as a computer to multiply two binary numbers, which is(More)
INTRODUCTION Acute Pancreatitis (AP) is one of the common conditions encountered in the emergency room. The course of the disease ranges from mild form to severe acute form. Most of these episodes are mild and spontaneously subsiding within 3 to 5 days. In contrast, Severe Acute Pancreatitis (SAP) occurring in around 15-20% of all cases, mortality can range(More)
Both WHO and IAP encourage using combination vaccines, wherever feasible. The phase III trial reported here was conducted to assess and compare the immunogenicity, tolerability and safety of two quadravalent vaccines, Quadrovax(®) (new vaccine), and TETRAct-Hib(®) (available in the market) in a multicentre study, in India. In all, 361 infants aged 6-8 weeks(More)
Anal canal malignancy is one of the dreadful conditions. Most of the anal canal malignancies are squamous cell carcinomas for which the treatment is well established and the prognosis is usually favourable. Small cell carcinoma of anal canal is a very rare condition and poorly understood, which can present as haemorrhoids in its early stages and has an(More)
Composites are emerging as realistic alternatives to the metal alloys in many applications like automobiles, marine, aerospace applications, sports goods, etc. Fiber composites offer many advantages such as low specific gravity, tensile strength and modulus, compressive strength and modulus, better fatigue strength, etc. Due to the low specific gravity the(More)
