Lullaby: Environmental Sensing For Sleep Self-Improvement

We are developing a system to help users improve the quality of their sleep by monitoring environmental factors that disrupt sleep and providing feedback. This system, called Lullaby, has several design goals. Lullaby’s sensor suite should be practical for deployment into bedrooms: it must be unobtrusive, inexpensive, and respect users’ privacy in this sensitive context. Lullaby should identify...

Analysis of SHA-512/224 and SHA-512/256

In 2012, NIST standardized SHA-512/224 and SHA-512/256, two truncated variants of SHA-512, in FIPS 180-4. These two hash functions are faster than SHA-224 and SHA-256 on 64-bit platforms, while maintaining the same hash size and claimed security level. So far, no third-party analysis of SHA-512/224 or SHA-512/256 has been published. In this work, we examine the collision resistance of step-redu...

Npgrj_nn_1413 512..518

Neurobiological studies demonstrate the amygdala’s role in emotional memory, and psychological studies suggest a particular pattern: enhanced memory for the gist but not the details of complex stimuli. We hypothesized that these two findings are related. Whereas normal (n 5 52) and brain-damaged (n 5 22) controls showed the expected enhancement of gist memory when the encoding context was emoti...

This paper presents the algorithmic aspects of organization of a lowcomplexity fully parallel processor unit for constant matrix-vector products computing. To reduce the hardware complexity (number of twooperand multipliers), we exploit the Winograd’s inner product calculation approach. We show that by using this approach, the computational process of calculating the constant matrix-vector prod...
