    Performance analysis of packet cooperative relaying system and the effect of packet length on performance by Shao-yang LIU, Yong XI, Ying LI, Ji-bo WEI, LISTERBurr A

    Published 2012-09-01
    “…The packet error rate(PER)of the packet cooperative relay system for both(amplify-and-forward)and DF(decode-and-forward)schemes in the high signal-to-noise ratio(SNR)region was analyzed,and the effect of packet length on PER performance was studied.It is shown that both AF and DF achieve the same diversity gain in terms of PER,but with different coding gains depending on packet length.Different from the prior research,if considering prac-tical packet lengths,the DF scheme always achieves better performance than the AF scheme,with shorter packet length,the advantage of DF over AF is more obvious.For large enough packet length,AF performance approaches that of DF.It is also found that the optimal relay will always be located in the middle of the two nodes for AF regardless of packet length,while for DF,when packet length becomes large,the optimal relay moves from close to the source towards the midpoint.…”

    Human Reliability Analysis in Acetylene Filling Operations: Risk Assessment and Mitigation Strategies by Michaela Balazikova, Zuzana Kotianova

    Published 2025-04-01
    “…It is also evident that human behavior is often the main or significant cause of system failures. Identifying human error is challenging, particularly when it comes to determining the exact moment when an error occurred that led to an accident, as errors develop over time. …”

    Differential fault analysis on EMV application cryptogram by Qian PENG, Zeng-ju LI, Ru-hui SHI

    Published 2016-04-01
    “…The process of application cryptogram in EMV was researched and dummy bits in session key were found.Based on the session key’s dummy bits and compressive property of DES’s Sbox,much information of the application cryptogram master key was got by using safe-error attack.The differential fault attack model and steps to implement the attack were proposed,two key factors(the probability of generating wrong key and the probability of collision happening) affecting an attacking result were analyzed.The theoretical result and simulation of the attack were given.The experiment results show that the two keys could be distinguished in a real attacking when the dif-ference of two key’s collision probability was bigger than 0.003 5.The dummy bits in the key will increase the dif-ference and make distinguishing easier.Finally,several countermeasures against the attack were proposed.…”
