Data hiding and detection in Office Open XML (OOXML) documents
(2011-03-01)
With the rapid development and popularity of information technology, criminals and mischievous computer users are given avenues to commit crimes and malicious activities. One of the commonly used tactics, called steganography, ...
Profile extrusion of wood plastic cellular composites and formulation evaluation using compression molding
(2010-05-01)
Wood Plastic Composites (WPCs) have experienced a healthy growth during the last decade. However, improvement in properties is necessary to increase their utility for structural applications. The toughness of WPCs can be ...
Islanding detection in distribution system embedded with renewable-based distributed generation
(2012-12-01)
Classical view of power system is characterized by a unidirectional power flow from
centralized generation to consumers. Power system deregulation gave impetus to a
modern view by introducing distributed generations (DGs) ...
Piezoelectric flexing and output voltage of a microchannel heat engine
(2010-08-01)
In this thesis, a new model is formulated for a piezoelectric membrane and fluid motion in a microchannel heat engine. A new slug flow model is developed for droplet motion in a circular cross-section channel. The model ...
Effective design of multiplexing network for applications in communications satellites
(2011-07-01)
Microwave multiplexing networks are widely used in satellite communication systems. Their performances, such as the insertion loss and rejection between channels, are extremely critical. This research aims at effective ...
Optomal three-time slot distributed beamforming for two-way relaying
(2010-08-01)
In this study, we consider a relay network, with two transceivers and r relay nodes. We
assume that each of relays and the two transceivers have a single antenna. For establishing
the connection between these two transceivers, ...
Investigation of a hydrogen production process through aluminum and water chemical reaction
(2019-12-01)
This thesis reported a novel hydrogen production experimental set up, which utilized the chemical reaction between aluminum and water to produce hydrogen. The constructed experimental setup had an aluminum powder spraying ...
Multimodal series elastic actuator for human-machine interaction with applications in robot-aided rehabilitation
(2019-11-01)
Series elastic actuators (SEAs) are becoming an elemental building block in collaborative robotic systems. They introduce an elastic element between the mechanical drive and the end-effector, making otherwise rigid structures ...
Design and development of an autonomous scaled electric combat vehicle
(2019-04-01)
Current literature pertaining to multi-steerable mobile robots and the progression of military vehicles in the past few decades suggest a lack of effort in pursuing advanced technologies in this joint area. As a result, a ...
Simulation of microgrid system and low-cost wireless communication network
(2019-08-01)
The MATLAB/SIMULINK model of a microgrid system is presented in this thesis. The microgrid consists of a converter-fed distributed generator photovoltaic array with maximum power point tracking, a converter-fed battery ...
