چکیده
Abstract We discuss some testable predictions of a non-supersymmetric SO(10) model supplemented by Peccei-Quinn symmetry. utilize symmetry breaking pattern that yields unification the Standard Model gauge couplings, with scale also linked to inflation driven an singlet scalar field Coleman-Weinberg potential. Proton decay mediated superheavy bosons may be observable at proposed Hyper-Kamiokande experiment. Due unbroken Z 2 from SO(10), predicts presence stable intermediate mass fermion which, together axion, provides desired relic abundance dark matter. The topologically monopoles and strings survive inflation. present in Universe level. estimate stochastic gravitational wave background emitted show it should number planned space land based experiments. Finally, we how observed baryon asymmetry is realized via non-thermal leptogenesis.

Model Predictive Inferential Control of a Distillation Column
Typical production objectives in distillation process require the delivery of products whose compositions meet certain specifications. The distillation control system, therefore, must hold product compositions as near the set points as possible in faces of upset. In this project, inferential model predictive control, that utilizes an artificial neural network estimator and model predictive cont...

In this article, a new combined approach of a decision tree and clustering is presented to predict the transmission of genetic diseases. In this article, the performance of these algorithms is compared for more accurate prediction of disease transmission under the same condition and based on a series of measures like the positive predictive value, negative predictive value, accuracy, sensitivit...
متن کاملDesigning a novel structure of explicit model predictive control with application in a buck converter system
This paper proposes a novel structure of model predictive control algorithm for piecewise affine systems as a particular class of hybrid systems. Due to the time consuming and computational complexity of online optimization problem in MPC algorithm, the explicit form of MPC which is called Explicit MPC (EMPC) is applied in order to control of buck converter. Since the EMPC solves the optimizati...

متن کاملRobust Model Predictive Control for a Class of Discrete Nonlinear systems
This paper presents a robust model predictive control scheme for a class of discrete-time nonlinear systems subject to state and input constraints. Each subsystem is composed of a nominal LTI part and an additive uncertain non-linear time-varying function which satisfies a quadratic constraint. Using the dual-mode MPC stability theory, a sufficient condition is constructed for synthesizing the ...
