Research ArticleOpen accessIn the author namesA Developed Version of Conjugate Gradient Method With a New Parameter for Dai-Liao Conjugacy Condition With an Application to Solar PanelAhmad Alhawarat, Ramadan Sabra, Mehiddin Al-Baali et al.Conjugate Gradient (CG) methods are broadly employed in solving bigger-scale unconstrained optimization problems. Two famous methods are the Hestenes–Stiefel (HS) as well as Polak–Ribière–Polyak (PRP) CG methods, which usually work well in practice. However, they cannot satisfy the Global Convergence (GC) property. To retain and enhance the previous practical behavior as well as rectify the latter difficulty, this paper constructs … …Journal of Computer Science, Vol. 21, Issue 7 · 15 Jul 2025 · 3,147 accessesView PDFCite
Research ArticleOpen accessIn the author namesDeveloping a Prototype for Sun Tracker System Based on IoT: Controlled by Mobile App and Online Database MonitoringIsmail Ismail Yusuf Panessai, Muhammad Modi bin Lakulu, Siva Kumar A/L Subramaniam et al.IoT (Internet of Things) has become a separate research field since the development of internet technology and other communication media.

Research ArticleOpen accessIn the author namesDynamical Analysis on the Transmission of Pertussis with Maternally Derived ImmunityAisha Aliyu Yakubu, Farah Aini Abdullah, Ahmad Izani Md Ismail, Yazariah Mohd YatimA susceptible-infected-recovered compartmental model incorporating maternally derived immunity compartment is analyzed in this study. The stability of the pertussis-disease-free and endemic equilibrium is studied. The basic reproduction number is obtained and its behavior analyzed by varying parameters. Numerical simulations indicated that when the waning parameter is increased, the frequency at which the population attains stability varies. However, the infected population … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 26 Jun 2020 · 6,294 accessesView PDFCite
Research ArticleOpen accessIn the author namesAn Improved Time Domain Pitch Detection Algorithm for Pathological VoiceMohd Redzuan Jamaludin, Sheikh Hussain Shaikh Salleh, Tan Tian Swee et al.Problem statement: The present study proposes a new pitch detection algorithm which could potentially be used to detect pitch for disordered or pathological voices. One of the parameters required for dysphonia diagnosis is pitch and this prompted the development of a new and reliable pitch detection algorithm capable of accurately detect pitch in disordered voices. Approach: The proposed method applies … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 21 Nov 2011 · 7,668 accessesView PDFCite
Research ArticleOpen accessIn the author namesV-Band Fade Dynamics Characteristics Analysis in Tropical RegionKhairayu Badron, Ahmad Fadzil Ismail, Jafri Din, Ahmad Tharek Abdul RahmanProblem statement: Satellite operations at V-band in tropical and equatorial regions are constrained as a result of attenuation from rain. Approach: Statistics for 20 consecutive months of V-band terrestrial link signal attenuation measurements in Malaysia were presented in this analysis. Such information was considered very pertinent for Earth-space communication link design and can be used for initial groundwork plan for … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,802 accessesView PDFCite
