Dependence on Blockchain Technology for Future Cybersecurity Advancement: A Systematic Analysis

Review Article of American Journal of Computer Sciences and Applications Dependence on Blockchain Technology for Future Cybersecurity Advancement: A Systematic Analysis Author: Ayman Abdulsalam Mohamed Al-Dherasi, Co-Author: Albert Annor-Antwi Supervisor: Dr. Yang Chunting School of Electrical and Electronic Technology and Computer Science, Zhejiang University of Science and Technology Purpose: The aim of this research is to thoroughly analyze blockchain with respect to the role it plays in cybersecurity, and how this role may affect the future of blockchain and cybersecurity. Also, gaps are identified along with the shortcomings that cause these gaps. This research also identifies possible solutions to the gaps or issues. Method: the research approach used here is a review of the literature using the systematic-analysis technique. Other works that address various aspects of blockchain are analyzed in-depth to show its effectiveness. Results: there is a great possibility that blockchain is one of the future’s greatest cybersecurity solutions. Among the major issues include quantum computing, user habits, and conflicting interests. All these issues have various ways through which they can be addressed effectively in order to brighten the future of blockchain’s applicability in cybersecurity. Conclusion: blockchain, as it is, promotes fraud in cryptocurrency and therefore needs modification. Blockchain only needs reinforcement from technologies such as Artificial Intelligence and Machine learning to make it the future’s most dependable cybersecurity provider.

Research on Rate Monotonic Algorithm and Schedulability Analysis in Real-Time System

Research Article of American Journal of Computer Sciences and Applications Research on Rate Monotonic Algorithm and Schedulability Analysis in Real-Time System Shaohui Zhang School of Network Engineering, Zhoukou Normal University, Zhoukou 466001, China. Rate monotonic scheduling algorithm (abbr. RM) is one of the main algorithms in real-time systems, but its operation efficiency is low relatively. In this paper, two-level scheduling method is used to improve the operational efficiency of RM algorithm, and the basic principle of computer processor in real-time system is analyzed, and the RM scheduling algorithm is implemented concretely. Considering the shortcoming of RM algorithm, a modified RM algorithm based two-level scheduling strategy is proposed. As a result, the performance and reliability of real-time system is increased, and the applicability of the method is widened. Keywords: Real-Time System; RM Algorithm; Reliability; Schedulability ...

ADOPTION OF IFÁ AS A COMPUTER-BASED INFORMATION SYSTEM

Research Article of American Journal of Computer Sciences and Applications ADOPTION OF IFÁ AS A COMPUTER-BASED INFORMATION SYSTEM Yusuf Lateef Oladimeji1*; Ibharalu, Friday Thomas1; Emmanuel, Jadesola Adejoke2 1Department of Computer Science, College of Physical Sciences, Federal University of Agriculture, Abeokuta, Nigeria 2Department of Mathematical Sciences, Achievers University, Owo, Nigeria Ifá scholars have primarily focused on its sociological and linguistic aspects while the scientific and computer aspects have been variously neglected. This paper explored the mathematical and computer model of Ifá corpus, which will assist Ifá priests to use the oracular process to simulate Ikin (the sixteen sacred palm nuts) and Ọ̀pẹ̀lẹ̀ (the divining bead chain) on the way to produce Odù (Ifá poetries) signatures. Each signature links the 256 Odùs in the database which invariably retrieved the corresponding verses with conforming sacrifices or advices. Microsoft Visual Studio.Net Express 2018 Community Edition on Window 10 Professional, 64-bit Operating System with Intel core duo CPU at 2.60 GHz, 12 GB memory was used to implement Ifá Application Tool (IAT). IAT interface supported Ikin and Ọ̀pẹ̀lẹ̀ simulation, the manual inscription of Odù signature, display of verses, stories, advises and recommended sacrifices. Usability testers scored the tool high in the ease of finding information within the user interface while it was above average in the skill to capture essential features for Odù divination accomplishments. This model supported Ifá professionals to make informed decisions and assessment by eliminating the level of ambiguity to interpret Odù corpus with a clear demarcation of its meanings.

Design of NSGA-III Tuned FPC for AMSS

Research Article of American Journal of Computer Sciences and Applications Design of NSGA-III Tuned FPC for AMSS Fengyang Lu1, Xiaolu Xu1, Hengbo Zhao1 1Luoyang Optoelectronic Technology Development Center, Luoyang, China. Airborne missile servo system (AMSS) is a complex time-varying nonlinear system and the design of which is a multi-objective optimization problem. Fuzzy PID controller (FPC) is demonstrated appropriate for complex time-varying nonlinear systems but the design of which needs a tedious trial and error process. Non-dominated Sorting Genetic Algorithm III (NSGA-III) is a multi-objective evolutionary algorithm with good generality and robustness which can do a big favor for parameter tuning of complex system. This paper develops NSGA-III for parameter tuning in design process of FPC. Resulting FPCs are tested with model of AMSS on simulink. For further comparison, performance of conventional PID controller and sectional PID controller which is widely used in the engineering are also shown. Comparison shows that NSGA-III tuned FPCs have the better performance in AMSS. Keywords:  NSGA-III; FPC; AMSS ...
