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 ...

Ascertaining the impact of Temperature, Rainfall, Water level, and Water discharge on Sediment Yield

Research article of American Journal of Computer Sciences and Applications Ascertaining the impact of Temperature, Rainfall, Water level, and Water discharge on Sediment Yield Balogun O*, Ogunseye A.A, Hinmikaiye J, Adegbenle A.A, Oyebode A.A, Akinshola J Department of Computer Science Babcock University, Nigeria The state of our natural environment is continuously changing. Various texts, global environmental monitoring bodies and environmental focused research groups agree that the deterioration, if not checked, will in the nearest future make it impossible for all living things to continue to exist in the ways we are accustomed to. As Earth’s temperature steadily increases, so has its sea level. This has brought about a lot of changes in the landscape of different catchment areas which is as a result of flooding. Flooding, in turn, has also resulted in death and proliferation of water borne diseases This work is motivated by the need to understand what factors mostly affect sediment yield in order to safe guard against its effects. The work takes a look into temperature, rainfall, water level, and water discharge factors from Oyan gauging station of the Ogun-Osun River basin, in the south western part of Nigeria. Our results show that all factors considered have a Sconsiderable effect on sediment yield. Keywords:impact of Temperature, Rainfall, Water level, and Water discharge, Sediment Yield ...
