In this paper, we extend our evaluation of the hardware performance of 14 Round 2 SHA-3 candidates, presented at CHES 2010, to the case of high security variants, with 512 bit outputs. A straightforward method for predicting the performance of 512-bit variants, based on the results for 256-bit versions of investigated hash functions is presented, and confirmed experimentally. The VHDL codes for...

Image data compression by fractal techniques has been widely investigated. Although its high compression ratio and resolution-independent decoding properties are attractive, the encoding process is computationally demanding in order to achieve an optimal compression. A variety of speed-up algorithms have been proposed since Jacquin published a novel fractal coding algorithm. Unfortunately, the ...

The study was conducted to evaluate and compare the effects of feed additives on ruminal fermentation, nutrient digestibility and performance of lambs fed diets containing 60% wet brewers grains (WBG). In Experiment 1, two simultaneous trials were conducted. Fifty intact (20.2±0.8 kg BW) lambs were used in a feedlot trial and 10 (rumen cannulated; 32±1 kg BW) in a digestion trial. The pH, volat...

A collision attack on NaSHA-512 was proposed by L. Ji et al. The claimed complexity of the attack is 2. The proposed attack is realized by using a suitable differential pattern. In this note we show that the correct result that can be inferred from their differential pattern is in fact a conditional one. It can be stated correctly as follows: A collision attack on NaSHA-512 of complexity k = 1,...

A common task in medical image analysis is the alignment of data from different sources, e.g., X-ray images and computed tomography (CT) data. Such a task is generally known as registration. We demonstrate the applicability of automatic differentiation (AD) techniques to a class of 2D/3D registration problems which are highly computationally intensive and can therefore greatly benefit from a pa...

Background. This study aimed to assess the relationship between diabetes, obesity, and hepatic steatosis in patients undergoing liver resection and to determine if these factors are independent predictors of major complications. Materials and Methods. Analysis of a prospectively maintained database of patients undergoing liver resection between 2005 and 2012 was undertaken. Background liver was...

In this paper, we present a near-collision attack on the compression functions of Dynamic SHA2 for all the output sizes. For the Dynamic SHA2-224/256, the complexity is about 2 operations and for the Dynamic SHA2-384/512, the complexity is about 2. 1 Description of Dynamic SHA2 The Dynamic SHA-2 [1] is an iteration cryptographic hash function family which is built with the design components fro...

Sixteen Mediterranean pluriparous buffaloes were subdivided into two uniform groups of eight animals. The average weight of the two groups at the start of the trial was 671.2 and 656.7 kg. The number of days from calving were 33.4 and 33.3, and the average milk production was 12.73 and 12.33 kg/d. The trial lasted for 114 days, and was divided into two sub-periods of 58 and 56 days. The two die...

introduction: candidiasis, as an opportunistic infection, is caused by the candida species. although candida albicans is classified in the body as an endogenic flora, it plays an important role in creating candida related diseases. candida vulvovaginitis in pregnant women, diabetes mellitus patients and those using multiple antibiotics and contraceptive drugs demonstrates the high resistance of...
