We analyze two ordinary differential equation (ODE) models for atherosclerosis. The ODE models describe long time evolution of plaques in arteries. We show how the dynamics of the first atherosclerosis model (model A) can be understood using codimension-two bifurcation analysis. The Low-Density Lipoprotein (LDL) intake parameter (d) is the first control parameter and the second control paramete...

This paper investigates options to complement a diesel engine airpath feedback controller with feedforward. The control objective is track the intake manifold pressure and exhaust gas recirculation (EGR) rate targets by manipulating EGR valve variable geometry turbine (VGT) while satisfying state input constraints. based on rate-based Model Predictive Control (MPC) that provides integral action...

Abstract. In this paper, we propose a novel low dimensional manifold model (LDMM) and apply it to some image processing problems. LDMM is based on the fact that the patch manifolds of many natural images have low dimensional structure. Based on this fact, the dimension of the patch manifold is used as a regularization to recover the image. The key step in LDMM is to solve a Laplace-Beltrami equ...

Two new contributions are presented here. This paper proposes using a Model Predictive Control (MPC) incorporating a Radial Basis Function (RBF) Network Observer for the fuel injection problem. Firstly a RBF Network is used as an observer for the volumetric efficiency of the air system. This allows for gradual adaptation of the observer, ensuring the control scheme is capable of maintaining goo...

Untuk mengoptimalkan udara murni yang masuk ke intake manifold dan mengurangi kadar emisi gas buang maka banyak dilakukan pengembangan-pengembangan. Salah satunya adalah penggunaan alat Oil Catch Tank (OCT). Fungsi utama dari untuk mencegah partikel minyak ataupun uap oli kembali saluran intake. Blow by crankcase akan menuju tabung terlebih dahulu blow ini terperangkap karena adanya media filte...

A mobile robot typically has access to a high dimensional stream of multi-modal sensor information. Modern mobile robots navigate uncertain environments using complex mixtures of camera, laser, and sonar sensor data. Manual calibration of these sensors is a tedious process that involves determining sensor behavior and geometry through model specification. To automate the construction of sensor ...

A new approach called Flow Curvature Method has been recently developed in a book entitled Differential Geometry Applied to Dynamical Systems. It consists in considering the trajectory curve, integral of any n-dimensional dynamical system as a curve in Euclidean n-space that enables to analytically compute the curvature of the trajectory or the flow. Hence, it has been stated on the one hand th...
