This paper describes the design of RESTORE, which is a framework for providing in-network event correlation and storage service for sensor environments. RESTORE uses a data-centric approach in which it partitions a sensor network into zones and maps every event to a zone. The sensor nodes in a zone make use of their cooperative storage resources and redundancy to improve information availabilit...

A new concept, that of "buffer capacity," is defined for potassium-buffering mechanisms in neural tissue. Buffer capacities for different mechanisms can be added and compared, thus simplifying quantitative assessment of diffusion, cytoplasmic uptake, and spatial buffering under varied conditions. The characteristic frequency components for potassium disturbances due to neural events are identif...

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...

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...

Availability of georeferenced yield data involving different crops over years, and their use in future crop management, are a subject growing debate. In 9 hectare field Northern Italy, seven years data, including wheat (3 years), maize for biomass (2 sunflower, sorghum, comprising remote (Landsat) normalized difference vegetation index (NDVI) during central stages, soil analysis (grid sampling)...

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...
