as technology scales deep into the nanometer regime, on-chip communication becomes more susceptible to transient noise sources, such as crosstalk, external radiation, and spurious voltage spikes. the network on chip s modularity and reusability has brought about the use of error control methods to address transient errors in network on chip links.in this work, we design a fault tolerance router...

A novel VCO topology is proposed that combines the low power of –gm oscillators with the inherent buffering of Colpitts oscillators. Using this topology, a quadrature VCO (QVCO) was implemented in 0.13 μm digital CMOS consuming 32 mW at 20 GHz with just over 10% tuning range. The measured phase noise of the QVCO at 20.17 GHz is -102.41 dBc/Hz at 1 MHz offset. Because the load is isolated from t...

We present a novel 3D object retrieval method that relies upon a hybrid descriptor which is composed of 2D features based on depth buffers and 3D features based on spherical harmonics. To compensate for rotation, two alignment methods, namely CPCA and NPCA, are used while compactness is supported via scalar feature quantization to a set of values that is further compressed using Huffman coding....

One of the most important items for better file system performance is efficient buffering of disk blocks in main memory. Efficient buffering helps to reduce the widespeed gap between main memory and hard disks. In this buffering system, the block replacement policy is one of the most important design decisions that determines which disk block should be replaced when the buffer is full. To o...

Several studies, carried out mainly in the United States and Canada, have suggested that recent immigrants are generally healthier than native-born populations in spite of the fact that they frequently have a lower socioeconomic status and less access to healthcare services. This “epidemiological paradox” has been called the “healthy immigrant” effect and is usually attributed to a self-selecti...

We describe the practical and fundamental limitations of the more prominent optical buffering approaches. The architectural implementation and needs of an optical packet switch are used as a foundation for the study. We also present initial results for a buffered, all-optical, 40 Gb/s packet switch. c © 2007 Elsevier B.V. All rights reserved.

The process that creates stereo images typically takes from 1.5 to 2 times longer than the algorithm for mono images. This paper presents a fast image-based algorithm for computing stereo images, that needs a little more time than the algorithm for mono images. The presented algorithm uses a single image with depth information (e.g. z-buffer) as an input and produces two images for left and rig...

The mobile phone plays an entertainment role in human life with the help of heterogeneous network by accessing multimedia content. But users faces a certain problems while access multimedia like long buffering time and intermittent disruption due to gap between demand traffic and link capacity, along with time varying link condition. The proposed technique focus on providing adaptive video stre...

Current interfaces for navigating digital documents use a standard point-andclick cursor to indirectly manipulate pages. We are presenting an interface that allows for direct and natural manipulation of a digital document by making utilizing the user’s ability to expertly navigate a book. This device allows for controlling the degree of bend in a virtual page (in two degrees of freedom), turnin...
