Research ArticleOpen accessIn the abstractDesigning of PID Controller for Discrete Time Linear System Using Balanced Approach Reduced Order ModelC.S. Ravichandran, S. Subha Rani, T. ManikandanModeling physical systems usually results in complex high-order dynamic models. It is often desirable to approximate these models by simpler models with reduced order. This study deals with the design of discrete time linear system using a balanced approach reduced order model. The reduced order model retains the desired state variable which contains a significant contribution. A PID controller is … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,128 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Fuzzy Logic Controller for Real-time Energy Optimization of a Hybrid vehicleSk. Khairul Hasan, Anoop Kumar DhingraThe ability to combine positive features of an internal combustion engine with those of an electric motor has been fundamental to the advancement of the high-performance energy-optimized hybrid vehicles. However, due to a lack of reliable and realistic hybrid vehicle models, much of the hybrid vehicle controller research has been limited to computer simulations. To overcome this shortcoming, this paper … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 21 Oct 2020 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractCardiovascular Diseases Identification Using Wavelet Optimization and Modify Cuckoo Search AlgorithmBanit Negi, Abhilekh Bartwal, Agya Ram Verma et al.The problem the author aims to solve is the extraction of discriminatory features in ECG (Electrocardiogram) signals for classification purposes. The scope of the work is to propose a new method for building wavelets that best reflect the discriminatory capacity of ECG signals. The approach involves optimizing the wavelets specifically for the classification function under consideration. To address the problem, … …Journal of Computer Science, Vol. 19, Issue 8 · 3 Aug 2023 · 5,403 accessesView PDFCite
Research ArticleOpen accessIn the abstractUSING COLUMN GENERATION TECHNIQUE TO ESTIMATE PROBABILITY STATISTICS IN TRANSITION MATRIX OF LARGE SCALE MARKOV CHAIN WITH LEAST ABSOLUTE DEVIATION CRITERIAWanida Lerspipatthananon, Peerayuth CharnsethikulThe Least Absolute Deviation (LAD) method is the one of many methods used to estimate transition probability matrix of Markov Chain. It can be formulated as a Linear Programming Problem (LP) and solved using its regular state of the art software. However, when the Markov Chain has a large number of states and historical state probabilities data, the corresponding LP … …Journal of Mathematics and Statistics, Vol. 10, Issue 3 · 23 Sep 2014 · 7,116 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of the American with Disabilities Act on Public Education ExpendituresMark P. GiusSection 504 of the Rehabilitation Act of 1973 and the American with Disabilities Act (ADA) of 1990 were enacted in order to protect the rights of individuals with disabilities. These two laws have had a major impact on public schools, their offerings of services and their budgets. The purpose of the present study was to determine if passage of the … …Journal of Social Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 6,841 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation and Reliability for a Special Type of Semi-Markov ProcessVlad Stefan Barbu, Alex Karagrigoriou, Andreas MakridesThis work deals with multi-state systems modelled by means of semi-Markov processes. The sojourn times are seen to be independent not identically distributed random variables and assumed to belong to one of two different general classes of distributions so that the first class is closed under maxima and the second one is closed under minima. We obtain maximum likelihood estimators … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 20 Oct 2019 · 7,047 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Hybrid Approach to Process Planning: The Urban Traffic Controller ExampleJimoh Falilat Olaitan, Simon Parkinson, Thomas Leo McCluskeyAutomated planning and scheduling are increasingly utilised in solving evsery day planning task. Planning in domains with continuous numeric changes present certain limitations and tremendous challenges to advanced planning algorithms. There are many pertinent examples to the engineering community; however, a case study is provided through the urban traffic controller domain. This paper introduce a novel hybrid approach to state-space … …Journal of Computer Science, Vol. 13, Issue 8 · 23 Aug 2017 · 7,484 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel De-Oiling of Oil-WaterEmmanuel Ewa Ekeng, Jonah Chukwuemeka AgunwambaThe study anchors on developing a mechanistic model for oil-water separation. Over the years, researchers have been working on how to improve the quality of produced water effluent especially from oil and gas operations sent to the receiving waters. Despite the standard set for compliance by regulatory bodies like united nation agency, ministry, departments and other agencies both state and … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 2 Sep 2020 · 6,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of the Sheep Farming System in the Brazilian Semiarid from the Multivariate PerspectiveJanaina Kelli Gomes Arandas, Ângelo Giuseppe Chaves Alves, Olivardo Facó et al.This study aimed to characterize the purebred Morada Nova sheep and crossbred farming systems in Ceará State, Brazil, through multivariate analysis. The study was carried out in the Morada Nova municipality in Ceará. Thirteen representative Morada Nova pure sheep Breeders (MNB) and 48 crossbreds’ breeders of Morada Nova with other breeds (CMN) were interviewed. Was used a questionnaire-based including 12 … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 3 · 1 Jul 2020 · 7,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Discrete-Time Hazard Model for Loans: Some Evidence from Italian Banking SystemGiambona FrancescaProblem statement: The probability of default, PD, is a crucial problem for banks. In the last years international accords (Basel, Basel 2 and Basel 3) have incentived banks to adopt objectives systems to evaluating and monitoring risk of default in order to predict PD for new loans based on borrower’s characteristics. The aim of this study is to introduce a … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 14 Jul 2012 · 7,394 accessesView PDFCite
