FM band channel measurements and modelling
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2018)
As the demand for higher data rates increases every day, the need for new frequency bands becomes more and more prominent. The FM band between 88 and 108 MHz is one of the bands that are not fully utilized. This band for ...
Evaluation of dopamine signaling in the rat ventromedial striatum for varying reward proximity
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2020)
Dopaminergic neurons play an important role in reward-mediated learning and motor control. In this work, we studied the transient changes in dopamine concentration in the ventromedial striatum (VMS) or nucleus accumbens ...
Physical layer security schemes for wireless communication systems
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2016)
Security in wireless communications has always been a major concern due to the broadcast nature of the radio waves. Apart from the conventional cryptologic methods that are performed in the upper layers, physical-layer ...
Emulation techniques for small scale fading aspects of wireless channels by using reverberation chamber
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2018)
Reverberation chambers (RVCs) are used to provide an effective and reliable testbed for emulating wireless channel effects in the laboratory environment. Various techniques that enrich the capabilities of the RVC in channel ...
Design of a voltammetry system for in vivo measurement of dopamine concentration
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2018)
Dopamine has a critical role in motor control, motor learning, reinforcement learning, cognition, attention and motivation. Consequently, the physiology of the dopaminergic system is an important and highly active research ...
A high-resolution time to digital converter design for all digital phase-locked loops
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2021)
Phase-locked loops are one of the most significant modules that are used not only for communication circuits but also in other fields like biomedical and computer sciences. There are many types of PLLs such as Analog, ...
Impacts of climate change on extreme climate indices in Türkiye driven by high-resolution downscaled CMIP6 climate models
(MDPI, 2023)
In this study, the latest release of all available Coupled Model Intercomparison Project Phase 6 (CMIP6) climate models with two future scenarios of Shared Socio-Economic Pathways, SSP2-4.5 and SSP5-8.5, over the period ...
Mutual coupling compensation in arrays and its implementation on software defined radios
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2021)
Mutual coupling in antenna arrays is a classical problem that has been researched for sev eral decades. This thesis presents two different algorithms along with their experimental verification by developing two different ...
Directivity enhancement of 60 GHz microstrip patch antennas using dielectric fabry-perot resonantors
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2019)
The 60 GHz frequency band offers many opportunities for innovations in the wireless network technology, unlike other bands. Since the wavelength in the 60 GHz band is millimetric, this band can suitably represent the ...
Finite element analysis of cervical spine & finite element modeling of knee joint
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2017)
Finite Element (FE) analysis allows predicting the behavior of real life systems in controlled environment. In the recent decades, FE modeling has gained significant attention of the medical industry as well. There is no ...
