Research ArticleOpen accessAll words, across the recordCollision Avoidance Modelling in Airline Traffic Based on the Change of Airplane Movements and Dynamic CloudsYudhi Purwananto, Chastine Fatichah, Waskitho Wibisono et al.An Air Traffic Controller (ATC) system aims to manage airline traffic to prevent collision of the airplane, called the Collision Avoidance (CA). The study on CA, called Conflict Detection and Resolution (CDR), becomes more critical as the airline traffic has grown each year significantly. Previous studies used optimization algorithms for CDR and did not involve the presence of cumulonimbus clouds. … …Journal of Computer Science, Vol. 17, Issue 1 · 20 Jan 2021 · 7,237 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA New Approach for Sub-Channels Assignment in Downlink Fourth Generation Mobile SystemsFakhreddine Khelifa, Abdelaziz SametProblem statement: We proposed a new heuristic method for subchannels allocation problem in the context. Approach: In this system, OFDM transmission method has been used, in order to reduce the effect of multipath fading, OFDMA to achieve multiple access schemes and flexibility in resource allocation. Results: An adaptive method for subchannels allocation is necessary in order to exploit the multiuser … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 6,588 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA New Indexing Technique for Information Retrieval Systems Using Rhetorical Structure Theory (RST)Muhammad Shoaib, Abad Ali ShahEffective information retrieval requires an efficient indexing technique. With the availability of huge volume of information, it has become necessary to capture the semantic of the document, which is almost impossible with the existing techniques. Moreover in the existing technique the weights once assign are remains unchangeable through out the cycle. In this paper an indexing technique assignment using Rhetorical … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 7,406 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordState-Space Modelling of a Rocket for Optimal Control System DesignAliyu Bhar Kisabo, Aliyu Funmilayo Adebimpe, Odooh Clement Okwo, Sholiyi Olusegun SamuelIn this study, we present the derivation of the mathematical model for a rocket’s autopilot in state-space. The basic equations defining the airframe dynamics of a typical six-Degree-of-Freedom (6DoF) are non-linear and coupled. Separation of these nonlinear coupled dynamics is presented as lateral and longitudinal dynamic equations. The need to determine aerodynamic coefficients and there derivative components are brought to … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 25 May 2019 · 13,632 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOn the Dynamics of a General Predator-Prey SystemM. M.A. El-Sheikh, S. A.A. El-Marouf, Z. M. AlaofyProblem statement: In this study a general two dimensional predator-prey model is considered. The dynamic and existence of equilibrium points are studied. Conclusion/Recommendations: Hopf bifurcation is discussed. The existence and uniqueness of limit cycles is proved. Special cases are considered to justify our results. …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 28 Oct 2011 · 7,322 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPresentation of Four-stroke Engine Design ElementsRelly Victoria Virgil PetrescuHaving escaped the shadow of the global energy crisis by implementing nuclear fission, wind, solar, bioenergy, but also by producing and extracting (deep) gases capable of providing us with planetary reserves for two more. Or at least three thousand years, we have started to relax more energetically, but due to the huge pollution produced by cars, the rules of their … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 28 Apr 2020 · 6,950 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMarketing Management of Sustainable Development of Territories in RussiaIrina Skorobogatykh, Daria Malova, Zhanna Musatova, Ekaterina AgalarovaOver recent years a characteristic feature of many countries has been the soaring importance of certain territories both at the national and international levels. A region is considered of primary level when the national economic system evolves. At the regional level, development and management of a territory is perceived from the perspective of target groups of its consumers-residents, businesses, investors, … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 2 Feb 2016 · 7,311 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA MOBILE AGENT BASED INTRUSION DETECTION SYSTEM ARCHITECTURE FOR MOBILE AD HOC NETWORKSBinod Kumar Pattanayak, Mamata RathApplications of Mobile Ad Hoc Networks (MANETs) have become extensively popular over the years among the researchers. However, the dynamic nature of MANETs imposes a set of challenges to its efficient implementation in practice. One of such challenges represents intrusion detection and prevention procedures that are intended to provide secured performance of ad hoc applications. In this study, we introduce … …Journal of Computer Science, Vol. 10, Issue 6 · 28 Jan 2014 · 7,267 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Novel Method of Voltage Sag and Swell Estimation for Power System ApplicationsA. Vetrivel, Jovitha Jerome, N. MalmuruganThis study presents four simple mathematical models to build the voltage shape with the knowledge of few parameters and detects voltage sag and swells accurately. Fourier series, cubic polynomial, Rational functions and Sum of Sin functions are used in this study to model the voltage profile. A new algorithm is developed to detect sag or swell in all the four … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 4 Jul 2013 · 7,080 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Fuzzy Based Mechanism For Allocation of Grid ResourcesM. Poonguzhali, S. ShanmugavelOne of the main challenges in Grid computing is efficient allocation of resources (CPU-hours, network bandwidth) to the tasks submitted by users. In our previous work a technique to allocate resources in a grid environment using predicted data has been proposed. We propose utilization of the predicted data the resources were classified into three types; they are permanent resources, semi-permanent … …Journal of Computer Science, Vol. 9, Issue 5 · 23 May 2013 · 6,772 accessesView PDFCite
