Adaptive time-step control algorithm for nonlinear time-domain envelope transient
(2006)This thesis outlines a general method to analyze circuits with several time variables using a technique known as Multi Partial Differential Equation, MPDE. The key idea of MPDE is to convert the system of ordinary ... -
Context aware services for smart learning environments
(2009)This thesis describes a cost-effective infrastructure and implementation for building ubiquitous learning spaces. It uses techniques from the semantic web and ubiquitous computing to build a learner-centric service-based ... -
Defending against false data injection attacks in power systems: techniques for securing state estimation and distance protection
(2025)The digitalization of power systems—enabled by technologies such as digital substations and Wide-Area Monitoring, Protection, and Control (WAMPAC) systems—has improved automation, visibility, and system control. However, ... -
Design of a 6-DOF haptic interface for robotic teleoperation
(2008)Teleoperation has become increasingly important in medical applications, handling hazardous materials, as well as in other robotics applications. Force feedback in such systems is essential; therefore a haptic device is ... -
Estimation and detection theory in visible light communication systems: a perspective on realistic receivers
(2024)Visible light communications (VLC) has been proposed as a promising way for nextgeneration wireless communication networks to mitigate the scarcity of the radio frequency (RF) spectrum, and has consequently attracted ... -
Robust channel estimation, localization, and tracking in visible light systems under signal-dependent noise
(2025)Visible Light Communication (VLC) is an emerging wireless technology that employs light-emitting diodes (LEDs) or lasers to transmit data over the visible light spectrum. Due to its inherent advantages, such as license-free ... -
Steady state analysis of oscillators
(2010)A common method used for steady-state analysis of oscillators is called Harmonic Balance. Harmonic balance finds the steady-state solution directly in frequency-domain. However, Harmonic Balance is very sensitive to the ... -
Study of several problems in nonlinear control by backstepping
(2005)Adaptive control is investigated for a class of nonlinearly parameterized systems by backstepping. An adaptive controller is constructed for MIMO nonlinearly parameterized systems with nested triangular form. The design ... -
Transformerless current source converter-based battery energy storage systems
(2025)Conventional battery energy storage systems (BESSs) connected to medium-voltage ac grids, whether integrated with renewable energy sources (RESs) or used in battery charging applications, face several challenges, including ...
