Gallium nitride chemical mechanical planarization development through tool set-up, process and post CMP cleaning optimization
(2018-07)
In this thesis, a new Chemical Mechanical Planarization (CMP) process and a complementary tool set-up are introduced to enhance Gallium Nitride (GaN) material removal rates while controlling the post planarization surface ...
A syncronized routing problem for restoring inter-dependent infrastructure networks
(2018-05)
Disasters may cause significant damages in lifeline infrastructure systems (such as gas, power, water) and lead to long-lasting failures. It is important to repair the damaged components and restore the affected infrastructures ...
Digital oil refinery: utilizing real-time analytics and cloud computing over industrial sensor data
(2018-12-14)
This thesis addresses big data challenges seen in large-scale, mission-critical industrial plants such as oil refineries. These plants are equipped with heavy machinery (boilers, engines, turbines, etc.) that are continuously ...
Radiative energy and exergy analyses of spectrally-selective surfaces for CSP systems
(Inderscience Enterprises Ltd., 2018)
This work presents a new methodology for calculations of spectral radiative energy and radiative exergy to evaluate the performances of concentrated solar power (CSP) systems. Spectral radiative properties and the operating ...
An exact approach for a dynamic workforce scheduling problem
(2018-01)
Taking into account the global and national rules and regulations, assigning a given number of employees to planned shifts while paying attention to required working hours, rest times and off day/days is one of the most ...
Effect of pH on particle agglomeration and radiative transfer in nanoparticle suspensions
(2018-08)
Nanoparticle suspensions (NPSs) are solid-fluid mixtures where small dielectric or metallic particles (with sizes <100 nm) used in a base fluid. NPSs have unique and tunable thermo-optical properties, and for that reason ...
Investigation of flame characteristics in a turbulent premixed combustion
(2018-10)
In this thesis, the turbulent flame closure (TFC) model and coherent flame model (CFM) of turbulent premixed flames as steady state flow are used. In addition, large eddy simulation (LES) model as unsteady state flow is ...

Performance analysis of vertical underwater visible light communication link
(2018-07)
Demand for high-bandwidth underwater applications such as image and real-time video transmission, has been increasing parallel to the increase in maritime activities such as environment monitoring, navigation, ocean-pollution ...
A new LED driver design with CRM flyback topology and high power factor and low total harmonic distortion
(2018-01)
In many of today's solid-state lighting (SSL) applications, Critical Conduction Mode (CRM) Flyback PFC converter is a popular solution due to its limited component count and simple structure with respect to other switched ...
