Analysis, development, and control of multi-degree-of-freedom passive haptic devices
(2020-08-01)
Stability and transparency are key design requirements in haptic devices. Replacing conventional electric motors with passive actuators such as brakes or dampers can improve both stability and transparency as passive ...
Investigation of three integrated energy systems with desalination, heat storage, thermochemical cycles and heat upgrade
(2020-09-01)
This thesis study proposes three different novel renewable energy-based multigeneration integrated systems with molten salt heat storage and desalination options where copper-chlorine (Cu-Cl) and magnesium-chlorine (Mg-Cl) ...
Proposing effective coordinate search methods for solving large-scale expensive black-box optimization problems
(2020-08-01)
In engineering and science, optimization plays a vital role in many real-world applications. In this work, several novel optimization algorithms based on Coordinate Search (CS) algorithm are proposed. CS is a gradient-free ...
Design of a secure privacy preserving cloud based framework for sharing electronic health data
(2020-01-01)
There exists a need for sharing user health data, especially with institutes for research purposes, in a secure fashion. This is especially true in the case of a system that includes a third party storage service, such as ...
Effect of diameter ratios on the flow-sound interaction of the straight circular finned cylinders
(2020-01-01)
Finned tubes that are widely used in heat exchangers could be susceptible to the flow-excited acoustic resonance that generates intense pressure fluctuations, which may lead to premature fatigue failure of the tubes. This ...
Development of an integrated tracking control algorithm and a test platform for autonomous excavation
(2020-03-01)
Since construction is part of the industrial sector where a large amount of labor is required and workers operate under harsh environmental conditions, the transformation from manual to autonomous operation in modern ...
Combustion and emission characteristics of ammonia blended fuels in a spark-ignited engine
(2020-06-01)
Climate change and fossil fuel depletion has brought attention to the need for alternative fuels. Ammonia shows great potential as an alternative fuel because it is carbon-free and can be produced renewably. In this study ...
Analysis and techniques of data compression in smart grids in the context of IEC 61850 communication protocol
(2020-02-01)
A smart grid is characterized by a two-way communication between the generation and the loads in addition to the distributed energy resources, which dictated the integration of smart monitoring devices to achieve full ...
Design, analysis, and control of switched supercapacitor banks for e-transportation electric energy storage systems
(2020-07-01)
The hybridization of supercapacitors (SCs) with batteries in electric vehicles (EVs) improves the battery life, acceleration, and driving range. However, the efficiency of the power interface that unites the batteries and ...
Modeling and simulation of The CERTS Microgrid: a comparative study using PSCAD and MATLAB SIMSCAPE
(2020-04-01)
The legacy electric power system has grown in magnitude and complexity since its conception. This was a result of various advancements, such as the need to match the increase in power demand, and to address the shortage ...
