Laptop computers and tablet PCs currently exploit swap system with their second storage media as a cost effective solution to extend limited memory space. The rapidly evolving flash memory technology starts to replace the magnetic disks of these computers by flash memory due to its advantageous characteristics such as energy efficiency and mechanical shock resistance. Thus, we can imagine that ...

This chapter is to introduce NAND flash channel model, error correction codes (ECC) and signal processing techniques in flash memory. There are several kinds of noise sources in flash memory, such as random-telegraph noise, retention process, inter-cell interference, background pattern noise, and read/program disturb, etc. Such noise sources reduce the storage reliability of flash memory signif...

In 2010, Steve Jobs announced that Apple would no longer support Adobe Flash, an at-the-time popular set of tools for creating Internet applications. In the years following Jobs’ announcement, the use of Flash declined precipitously. Using data from an online labor market, we study how the market for Flash skills evolved and how Flash programmers fared. The large negative shock in the demand fo...

Abstract In 1989, den Boer presented the first card-based protocol, called “five-card trick,” that securely computes AND function using a deck of physical cards via series actions such as shuffling and turning over cards. This protocol enables couple to confirm their mutual love without revealing individual feelings. During secure computation it is important keep any information about inputs se...

Flash memory has gained tremendous popularity in recent years. A variant of flash, referred to as NAND flash, is widely used in consumer electronics products, such as cell-phones and music players while NAND flash based Solid-State Disks (SSDs) are increasingly displacing hard disk drives as the primary storage device in laptops, desktops, and even data centers. Computer architects have recentl...

With flash disks being an important alternative to conventional magnetic disks, various design aspects of DBMSs, whose I/O behavior is performance-critical, and especially their I/O architecture should be reconsidered. Taking the distinguished characteristics of flash disks into account, several flash-aware buffer algorithms have been proposed with focus on flash-specific performance optimizati...

When a short flash occurs in spatial alignment with a moving object, the moving object is seen ahead the stationary one. Similar to this visual "flash-lag effect" (FLE) it has been recently observed for the haptic sense that participants judge a moving hand to be ahead a stationary hand when judged at the moment of a short vibration ("haptic flash") that is applied when the two hands are spatia...

it is crucial to monitor the growth and development of a child in early stage of life to take early corrective action in time to ensure normal growth. child health card (chc) is a tool used to maintain records and monitor the under five children. the objective of this study was to find out the maternal awareness on chc and factor associated with its retention. this was a cross sectional analyti...

NAND flash memory has been the single biggest change to drive technology in recent years, with the storage medium showing up in data centers, laptops and in memory cards in mobile devices. It addresses the performance problems in storage. Data Deduplication is simple yet effective technology providing solution to the massive storage requirements of data. Deduplication removes redundant files/bl...
