Research ArticleOpen accessPhrase in the titleMathematical Modeling and Characterization of Thin Film, Narrow Gap Sensor Array Units (SAU)Mahmoud Z. IskandaraniDesign, modeling, testing and analysis multi-gap PbPc sensor array units for the purpose of gas detection are carried out. The tested devices showed reduction in conductance as a function of increasing gap width and reducing film thickness and an increase as a function of temperature up to 160°C. An observed morphological change in the sublimed film is realized at 190°C … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 6,856 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleMathematical Modeling of a Tactile Sensor with Applications in Minimally Invasive SurgeryAshkan Mirbagheri, Siamak Najarian, Javad Dargahi, Farhad Tabatabai GhomsheThis paper describes mathematical modeling of a novel supported tactile sensor. This system has only three or four sensing elements instead of an array configuration. By writing a code, together with using the piezoelectric capabilities of the finite element analysis software, it is possible to extract the stresses developed in the tactile membrane along the edges of the sensing elements, … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,186 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePredictive Mathematical Modeling and Classification of Retail Sales Orders Using AI Machine Learning TechniquesMohammad Subhi Al-Batah, Mowafaq Salem Alzboon, Hamzeh ZureigatThis study presents a systematic mathematical model known as a low-code approach to classifying retail sales orders by size using AI machine learning techniques within the Orange Data Mining platform. Leveraging a real-world sales dataset sourced from Kaggle, we implemented and evaluated ten classification models, including ensemble learners (AdaBoost, Gradient Boosting), probabilistic classifiers (Naïve Bayes), distance-based methods (kNN), and interpretable … …Journal of Computer Science, Vol. 22, Issue 3 · 10 Mar 2026 · 1,567 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleBioaccumulation of Cr(III) ions by Blue Green-alga Spirulina sp. Part II. Mathematical ModelingKatarzyna Chojnacka, Piotr M. WojciechowskiIn the present paper bioaccumulation of Cr(III) ions by blue-green algae Spirulina sp. is discussed. We found that the process consisted of two stages: passive in which Cr(III) ions are bound to the surface of cells, identical with biosorption and active, metabolism-dependent, in which Cr(III) ions are transported into the cellular interior. The passive stage occurs in both living and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 8,294 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleCHARACTERISTIC ANALYSIS OF DUAL GATE METAL OXIDE SEMICONDUCTOR FIELD EFFECT TRANSISTOR BY MATHEMATICAL MODELINGC.A. Abdul Nazar, V. KannanIn this study, the characteristics of DGMOSFET were obtained using mathematical modeling. The variations of characteristics were analyzed with different conditions into consideration. Different parameters behavior is analyzed, such as Transcapacitance variation with the gate voltage, threshold voltage variation with respect to lateral straggle parameter and temperature, mobile charge density variation is also analyzed and also the drain characteristics of … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 5 May 2014 · 6,618 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleMathematical Modeling of Drying Characteristics of Chilies in a Rotating Fluidized Bed TechniqueKittichai Triratanasirichai, Watcharin Dongbang, Worachest PirompugdProblem statements: The present study investigates experimentally the thin layer drying of chilies in the Rotating Fluidized Bed (RFB) technique and its mathematical modeling. Approach: The layer’s height was fixed at 4±0.5 cm. In addition, the drying air velocity and the centrifugal acceleration ratio were fixed at 2 m sec-1 and G = 2.5 (106 rpm), respectively. With 6 data … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 6,965 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleMathematical Modeling of the Three Phase Induction Motor Couple to DC Motor in Hybrid Electric VehicleZulkarnain Lubis, A. N. Abdalla, Mortaza, Ruzlaini GhonProblem statement: With emphasis on a cleaner environment and efficient operation, vehicles today rely more and more heavily on electrical power generation for success. Approach: Mathematical modeling the components of the HEV as the three phase induction motor couple to DC motor in hybrid electric vehicle was introduced. The controller of Induction Motor (IM) was designed based on input-output feedback … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,309 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Mathematical Modeling of the Turbulence Combustion Biodiesel in a Compression Ignition Engine: Theoretical FrameworkFrancis Mouzong Bongne, Zacharie Merlin Ayissi et al.The present work proposes a new model for biodiesel combustion in an internal combustion engine. This model first includes the balance equations of gas dynamics with heat release. Secondly, a model with special properties that take into account turbulence effects is incorporated. The chemical models implemented in this study are for a biofuel used at less than 100% and for … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 4 · 30 Sep 2024 · 5,021 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleStochastic and Deterministic Mathematical Modeling and Simulation to Evaluate the Novel COVID-19 Pandemic Control MeasuresEva Gupta, Nand Jee Kanu, Amartya Munot et al.Background: In India, the novel Coronavirus Disease (COVID-19) epidemic has grown to 17,00000 cases and around 38,000 deaths up to 30th July, 2020. The impacts of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic in India were studied using modified age-structured stochastic and deterministic mathematical models. Methods: A compartmental susceptible (S)-infected (symptomatic) (IS) infected (asymptomatic) (IN) recovered (R) i.e., … …American Journal of Infectious Diseases, Vol. 16, Issue 4 · 20 Nov 2020 · 8,456 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Mathematical Modeling Approach to Characterize Hormesis, Caloric Restriction and Toxicity in Mortality Data from Toxicity StudiesPatricia J. NeafseyThe mortality of a population reflects the combined effects of natural aging with environmental insults (e.g. toxicant exposure, caloric restriction, over feeding, infections, etc.). No single endpoint, such as carcinogenesis, completely describes toxicant-induced effects in laboratory animals. Mathematical models of mortality and time-dependent exposure to toxicants can yield indices of net injury from all causes. With careful manipulation of diet … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,160 accessesView PDFCite
