This paper addresses efficient hardware/software implementation approaches for the AES (Advanced Encryption Standard) algorithm and describes the design and performance testing algorithm for embedded system. Also, with the spread of reconfigurable hardware such as FPGAs (Field Programmable Gate Array) embedded cryptographic hardware became cost-effective.(More)

BACKGROUND Helping trainees develop appropriate clinical reasoning abilities is a challenging goal in an environment where clinical situations are marked by high levels of complexity and unpredictability. The benefit of simulation-based education to assess clinical reasoning skills has rarely been reported. More specifically, it is unclear if clinical(More)
Motivation: In the analysis of experiments that involves the high density of oli-gonucleotide chips, it is important to generate list of genes or 'targets' from the genomewide data set that contains a lot of information. Gene selection is a process that seeks to identify the most significant genes which reveal large expression changes between the baseline(More)
