Hardware Evaluation of SHA-3 Candidates
… and exploits on the cryptographic hash function, SHA-1, the most widely used hash function of the secure hashing algorithm family. Although these attacks do not work on SHA-2, the next in the series of the secure hashing algorithm family, the National Institute of Standards and Technology still …

SHA-less pipeline ADC design with sampling clock skew calibration
… the front-end sample-and-hold amplifier (SHA). However, in a SHA-less architecture the sampling clock skew between the sub-ADC and the multiplying digital-to-analog converter (MDAC) in the pipeline first stage results in gross conversion errors at high input frequencies. This skew effect …

An exploration of meaning in landscape architecture -redesigning Tsim Sha Tsui East waterfront in Hong Kong
Through an exercise to redesign Tsim Sha Tsui East waterfront in Hong Kong, this thesis explores different approaches to achieve meaning through design. A site survey and analysis is first carried out to address functional, social and potentially aesthetic issues on site and to identify objectives …

Stakeholder analysis : drawing methodological lessons from review of relevant literature
Stakeholder analysis (SHA) is an important tool in policy analysis, used to understand the actors who are affected by or have an effect on a particular policy. Its implementation spans a variety of sectors from government to corporate, and conservation to health. The widespread application of SHA …

Secure and Efficient Implementations of Cryptographic Primitives
… a hardware evaluation methodology to the NIST SHA-3 standardization process. Our research efforts cover both of the SHA-3 fourteen Second Round candidates and five Third Round finalists. We design the first SHA-3 benchmark chip and discuss the technology impact to the SHA-3 hardware evaluation …

Security proofs for the MD6 hash function mode of operation
… commonly-used hash functions, such as MD4, MD5, SHA-0, and SHA1 [13, 38]. These culminated with the celebrated work of Wang, Yin, and Yu from 2005, which demonstrated relatively efficient methods for finding collisions in the SHA-1 hash function [37]. Although there are several cryptographic hash …

An analysis of the bitcoin blockchain cryptography
… mining process relies on the hashing function SHA-256. There are strong indications that the Bitcoin mining process was exploited in 2010, only a year after its initial release [9]. This raises significant questions over the security of cryptocurrencies, and if they are to be used in the …

Effects of Adjustments to Wheelchair Seat to Back Support Angle on Head, Neck, and Shoulder Postures
… posture angles were used: sagittal head angle (SHA), cervical angle (CVA), and shoulder angle (SA). Results: There were highly significant differences on abled subjects for CVA and SA (p < 0.001) among the three seat to back support angles. CE had high validity for all angles (r = 0.99, 0.98, …

Assessing bioactivity of a bioactive peptide from the defensive skin secretion of Odorrana schmackeri
… cDNA sequence of a peptide, namely Brevinin-1-SHa, was identified through the method of “shotgun” cloning. The mature peptide structure was deduced from this cloned cDNA and isolated from the skin secretion sample by reverse-phase HPLC fractionation. The molecular weight of the peptide was then …

Design and analysis of hash functions
… developed based on this construction. MD5, SHA-0 and SHA-1 are currently the most widely deployed hash functions. However, they were all broken by Wang using a differential collision attack in 2004 [55-60], which increased the urgency of replacement for these widely used hash functions. …
