Energy efficiency analysis and improving performance of light emitting diodes
(2018-12)
Energy efficiency of light sources continually increases as the technology advance. Traditional light sources have inefficiency, large sizes, short life times and poisonous mercury vapor. On the other hand, the improvements ...
An investigation into hydrophobic micro-textured surfaces on heat transfer and surface wetting phenomenon during vapor condensation
(2018-12-28)
Efficiency and performance of a system that involves condensation process have been one of the primary considerations over the last decades for a number of applications including thermal management systems such as vapor ...
Rheology modifying agents : a key technology developed by using microorgsnisms
(2018-08)
Recent development in concrete technology enabled the design of highly flowable mixes with improved workability. These advanced mixes require incorporation of fine materials or viscosity modifying agents (VMA) to reduce ...
Investigation of thermal comfort performance of radiant heating systems: comparisons of different heating surface configurations
(2018-02)
This thesis is an experimental-numerical study for the thermal comfort assessment of radiant heating system for different heating configuration such as from a wall, ceiling and combination of both that is installed in a ...
FOVLC: Foveation based data hiding in display transmitters for visible light communications
(2018-05)
Visible light communications is an emerging architecture with unlicensed and huge bandwidth resources, security, and experimental implementations and standardization e orts. Display based transmitter and camera based ...
Integrated design and application of a campus-wide distributed-photovoltaic system
(2018-05)
After releasing the regulations on unlicensed electricity generation in Turkey, the main structure of the regulatory mechanism has just finished in 2014 and renewable energy generation started to grow dramatically. Ozyegin ...
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 ...
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 ...
