The past three decadeswitness a long-term intensive interest in researching a variety of control methods on wheeled mobile robots (WMRs), although the general nonholonomic systems have been investigated for more than one and half a century (Kolmanovsky & McClamroch, 1995). It is well-known that usually WMRs are characterized by non-integrable kinematic constraints, namely the nonholonomic const...

The problem of off-line reading of unconstrained handwritten words has been studied extensively due to its role in many important applications such as reading addresses on mail-pieces [3, 6, 11], reading amounts on bank checks [7, 10], extracting census data on forms [2, 9], and reading address blocks on tax forms [12]. The main challenges are wide variety of writing styles, poor image quality ...

This study extends the work of Baumgardner et al. (2009) in which measurements of trace gases and particles, at a remote, high altitude mountain site, 60 km from Mexico City were analyzed with respect to the origin of the air masses. In the current evaluation, the temperature, water vapor mixing ratio (WMR), ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2) and acyl peroxy nitrate (APN) ar...

Low-cost passive intelligent reflecting surfaces (IRSs) have recently been envisioned as a revolutionary technology capable of reconfiguring the wireless propagation environment through carefully tuning reflection elements. This paper proposes deploying an IRS to cover dead zone cellular multiuser full-duplex (FD) two-way communication links while suppressing user-side self-interference (SI) an...

A communication and control architecture of a multifunctional technology for flexible manufacturing on an assembly, disassembly, repair mechatronics line (A/D/RML), assisted by complex autonomous system (CAS), is presented in the paper. A/D/RML consists six-work station (WS) (ML) connected to cell (FC) equipped with six-degree freedom (DOF) industrial robotic manipulator (IRM). The CAS has its ...

This paper, proposes a methodology to implement a suitable nonsingular terminal sliding mode controller associated with the output feedback control to achieve a successful trajectory tracking of a non-holonomic wheeled mobile robot in presence of longitudinal and lateral slip accompanied. This implementation offers a relatively faster and high precision tracking performance. We investigate this...

This research aims to determine if the observed improvements using polyethylene (PE) waste in asphalt binder translate into better performance at mixture scale laboratory environment while overcoming stability and homogeneity issues experienced level. is accomplished through a round-robin multinational experimental program covering four continents, with active participation of eleven laboratori...

This paper proposed a neural network model algorithm control (NNMAC) method for the path tracking control of differentially steered wheeled mobile robots (WMRs) subject to nonholonomic constraints. The model algorithm control (MAC) is a one-step-ahead predictive controller, in which the control law is obtained by minimizing the output error. The MAC method needs the well known model of the cont...

Optimal Control and Estimation Strategies for Nonlinear and Switched Systems Mehdi Abedinpour Fallah This dissertation includes two main parts. In the first part, the main contribution is to use an inverse optimality approach to analytically solve the Hamilton-Jacobi-Bellman equation of a third order nonlinear optimal control problem for which the dynamics are affine and the cost is quadratic i...
