Determining thermal comfort in built environment using computational fluid dynamics simulations
(2017-06)
In this thesis, three-dimensional time-dependent Thermal Comfort (TC) conditions in an occupied room is investigated and determined. The room is considered with furniture of varying materials (i.e. steel, wood, etc.) and ...
Optimization and analysis of WLAN RF energy harvesting system architecture for low power wireless applications
(2017-01)
The presented work proposes a radio frequency (RF) energy harvesting circuit design, which scavenges energy from WLAN dual frequency band. In comparison to other available sources for energy scavenging, e.g. solar, wind ...
Vulnerability of speaker verification system under replay spoofing attack and investigation of synthetic speech detection
(2016-05)
Security issues have become major subject along with developments in the speaker verification system. Previous studies have shown that performance is still not fully proven for vulnerability. Simple and easy methods may ...

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 ...
