Performance improvement strategies for 802.11 network
(2017-08)
802.11 networks have enabled and are fueled by the proliferation of connected mobile devices with a wide variety of applications, which have been integral parts of our daily lives. Currently, IEEE 802.11ac is a state-of-art ...
Relay-assisted OFDM-based visible light communications
(2016-08)
In this study, a relay-assisted visible light communication (VLC) system where an intermediate light source cooperates with the main light source is investigated. Specifically, two light sources in an office space; one is ...
Gyroscopes based on acoustic waveguides
(2016-08)
We propose novel gyroscope architectures based on acoustic waves propagating in a waveguide. This thesis is composed of two parts. In the first part, the fundamentals of the proposed gyroscope are discussed. The new gyroscope ...
Effect of colour conversion layer on the optical and thermal efficiency of LED based liquid crystal displays
(2018.05)
In light-emitting diode (LED) lit liquid crystal displays (LCD), the colour gamut is related to the back-light unit (BLU) spectrum. The blue LED light is generally converted to green and red bands with phosphor mixtures. ...
Development of an accelerated Monte Carlo ray tracing based radiation heat transfer solver
(2017-07)
The Monte Carlo ray tracing (MCRT) is a semi-analytical stochastic method for the solution of radiative transfer equation (RTE). However, its high computation cost prevents its extensive use. In this study, an accelerated ...
M-pick fixed-priority selection and muxing
(2017-01)
In this thesis, we propose a class of logic architectures for multi-pick (m-pick) fixed-priority arbitration (FPA) and muxing. An m-pick FPA selects the m topmost requests out of n inputs with priority order. Arbiters ...
Design and quantitative analysis of a pulse wave velocity blood-pressure measurement subsystem with multiple-subject controlled experiments
(2018-08)
The main purpose of this study is to perform the pulse wave velocity (PWV) measurements with a new noninvasive optoelectronic continuous-time wearable sensor design and analyze the quantitative relation between the reference ...
Electrochemical evaluations of TiO2 nano films for advanced engineering applications
(2018-05)
This study evaluates the performance TiO2 nano-film for engineering applications, both in biomedicine and microelectronics, were Chemical Mechanical Planarization (CMP) is a main process used for planarizing the metal ...
OPLINQ: opportunistic link scheduling for massive device-to-device mmWave communication networks
(2017-01)
mmWave communications networking is a promising physical layer technology for the requirement of the huge bandwidth in next generation 5G infrastructures. One of the emerging important applications for 5G mmWave architectures ...
A custom-design atmospheric channel emulator for the performance evaluation of free space optical communication systems
(2017-08)
The properties of atmospheric chamber and measurement methods that are used in this system are explained and analyzed in detail. We present our own custom design atmospheric channel emulator for FSO system evaluations and ...
