Tribological capabilities of carbon based nano additives in liquid and semi-liquid lubricants
(2019-04-01)
The growing population, the environmental challenges and limitations of nonrenewable resources have enforced researchers to improve the energy efficiency and reduce energy wastage in all industrial sectors including ...
Numerical investigation of turbulent combustion regimes on localized forced ignition using stratified combustible mixture
(2019-03-01)
Localized forced ignition of turbulent stratified mixtures has been numerically analyzed based on three- dimensional Direct Numerical Simulations (DNS) for different values of Karlovitz number (Ka) corresponding to different ...
Enhancing the effectiveness of Stirling engine regenerators
(2019-04-01)
A discrete heat transfer model is developed to determine which parameters influence the effectiveness of Stirling engine regenerators and quantify how they influence it. It is revealed that the regenerator thermal mass ...
Design and control of resilient interconnected microgrids for reliable mass transit systems
(2019-03-01)
Mass transit systems are relied on a daily basis to transport millions of passengers and bring billions of dollars' worth of economic goods to market. While some forms of mass transit rely on a fuel, electrified railway ...
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 ...
Unsupervised brand name extraction using domain adaptation
(2019-08-01)
Business intelligence and analytics is an area of research that analyzes the existing business data to extract the insights needed for a successful business planning. Textual data derived from tweets, forum posts, and blogs ...
Proposing an ensemble-based model using data clustering and machine learning algorithms for effective predictions
(2019-08-01)
One of the most important tasks in machine learning is prediction. Data scientists use various regression methods to find the most appropriate and accurate model applicable for each type of datasets. This study proposes a ...
Robust controller design for active trailer steering systems of articulated vehicles using multi-objective optimization
(2019-08-01)
This thesis presents and evaluates an approach to the robust controller design for active trailer steering (ATS) systems to increase the safety of articulated vehicles. By applying a multi-objective evolutionary algorithm ...
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 ...
Controlling the Vienna rectifier using a simplified space vector pulse width modulation technique
(2019-11-01)
In this thesis, a simplified Space-Vector Pulse-Width-Modulation (SVPWM) technique for the Vienna rectifier is introduced to reduce the computational burden, the switching losses and the Total-Harmonic-Distortion (THD). ...
