We present new software speed records for several popular hash functions on low-end 8-bit AVR microcontrollers. Target algorithms include widely deployed hash functions like SHA-1 and SHA-256 as well as the SHA-3 (second round) candidates Blake-32 and Skein-256. A significant aspect of our implementations is that they reduce the overall resource requirements, improving not only execution time b...

Many models used to explain accuracy and response time in recognition memory have separated retrieval from decision: Retrieval produces a value of memory strength that drives a decision process characterized by evidence that does not change until a decision is reached. Cox and Shiffrin (2012) have used an alternative dynamic approach that assumes these stages interact: As time passes after pres...

ÐRecent technological advances in digital signal processing, data compression techniques, and high-speed communication networks have made Video-on-Demand (VOD) servers feasible. A challenging task in such systems is servicing multiple clients simultaneously while satisfying real-time requirements of continuous delivery of objects at specified rates. To accomplish these tasks and realize economi...
