Mathematical model of distal radius orientation

open access: yesFrontiers in Surgery, 2022
Distal radius orientation is important in evaluating Colles' fracture. In most cases, the wrist was protected by a bandage, splint, or cast. Therefore, it was difficult for the radiology technician to take perfect anteroposterior and lateral view ...

Mathematical model for pulsed chemotherapy

open access: yesITM Web of Conferences, 2015
A pulsed chemotherapeutic treatment model is investigated in this work. We prove the existence of nontrivial periodic solutions by the mean of Lyapunov-Schmidt bifurcation method of a cancer model. In this model we consider the case of application of two

Dynamic stability analysis of a fractional calculus-based colon cancer model with therapeutic interventions

open access: yesScientific Reports
Colon cancer is a high-risk malignant tumor worldwide. To address the limited efficacy and overlapping toxicity of current chemoimmunotherapy, this study establishes a fractional-order colon cancer model with a core architecture capturing the probiotics-

Mathematical model for knowledge testing

open access: yesLietuvos Matematikos Rinkinys, 2008
There is a mathematical model for obtaining test responses probability distribution proposed. This enables to formulate recomendations for selection of test items for different groups of tested population according to their attainment level.

Mathematical model of thermal aggregates [PDF]

open access: yesActa Montanistica Slovaca, 1998
Tepelné agregáty môžme charakterizova jako priemyselné pece s ve¾kou spotrebou energie. Jednou z možných ciest zníženia spotreby energie je optimalizácia a priebežné riadenie priemyselných tepelných agregátov pomocou simulaèných modelov. Východiskom
