On-line optimization of thermomechanical pulping rejects screen using modified sequential simplex method
(2003)The sequential simplex method (SSM) was blended with the Nelder and Mead method to create two separate simplex methods. The first method is the Equilateral Optimum Following Simplex (EOFS). In this method, the simplex ... -
Packet scheduling for AMC-based OFDMA wireless communication systems
(2008)In this thesis, we propose a basic priority and fairness (BPF) and a modified priority and fairness (MPF) based packet scheduling algorithms for adaptive modulation and coding (AMC) scheme based orthogonal frequency division ... -
Performance and emissions of a DI diesel engine fueled by different biodiesel blends
(2014-01-22)Biodiesel has been a promising clean alternative fuel to fossil fuels, which reduces the emissions that are released by fossil fuels, and possibly reduces the energy crisis caused by the exhaustion of petroleum resources ... -
RBF neural network based generalized predictive control for nonlinear stochastic systems
(2014-01-22)Almost all practical systems are nonlinear, which are subject to disturbances and contain uncertainties. In most cases, disturbances and uncertainties can be modeled as stochastic processes, which make it necessary to ... -
Robust and adaptive control via backstepping technique
(2005)Most of the control systems are designed using linear techniques, which have been well developed. Practical physical systems are typically nonlinear. Nonlinear control is one of the biggest challenges in modern control ... -
Robust control of DC-DC boost converter / by Hisham Mahmood.
(2008)In this thesis, a robust controller comprising of a PI with phase-lead compensator for a DC-DC boost converter designed using classical frequency response method is presented. The superior performance of this controller ... -
Robust H infinity model reference tracking control of singular systems using T-S fuzzy model and LMI
(2014-12-12)In this study, a Takagi-Sugeno fuzzy model based tracking controller is proposed for nonlinear high index singular systems with a guaranteed H1 model reference tracking performance. A coordinate transformation is introduced, ... -
Study of two different tunable vibration absorbers : variable stiffness absorber and variable damping absorber
(2003)A structure or machine w ill vibrate at the frequency of excitation when excited by a harmonic force. Vibration of the structure can be suppressed using a vibration absorber by setting the absorber’s natural frequency ... -
Travelling cable system : apparatus development, system modeling, and vibration control
(2005)The vibration of axially moving materials with arbitrarily varying length has received increased attention due to both the interesting behaviours of such systems and the many applications such as deep mine hoisting ... -
A Tunable high-static-low-dynamic-stiffness isolator and a fuzzy-neural network based active control isolator
(2009)Excessive vibration can be detrimental to a wide variety of structures and machines. Vibration isolation is an effective means to suppress vibration. This study focuses on development of some new techniques to improve ... -
UWB localization for autonomous indoor position control of VTOL UAVs
(2018)As the popularity of quadrotor Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicles (UAVs) grows, the need for reliable position estimation and control grows as well. Furthermore, with the size of these quadrotors ... -
Vibration control using switchable stiffness
(2015-01-13)Over the last decade, the switchable stiffness (SS) control strategy has seen renewed academic interest due to the need for effective vibration control techniques. The SS control strategy involves switching the system’s ... -
Vision-based trajectory tracking algorithm with obstacle avoidance for a wheeled mobile robot
(2005)Wheeled mobile robots are becoming increasingly important in industry as means of transportation, inspection, and operation because of their efficiency and flexibility. The design of efficient algorithms for autonomous ... -
Wave reflections in a semi-infinitely long cylinder with an attached solid of revolution
(2008)A numerical procedure is presented for the study of end reflections in a semi-infinitely long isotropic circular cylinder with attached piezoelectric patch. The hybrid method which combines the finite element formulation ...
