Air-ground channel modeling and waveform containment
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2017)
The content of this work is divided into two main parts. Part I is dedicated for characterizing Air-Ground channels. Applications using Air-Ground communications are expected to grow in the future. Low altitude phases of ...
Image enhancement through new techniques in computational photography
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2019)
Quality of a digital image depends on several factors operative during the image formation process, e.g. sensor defects, sensor dynamic range, poor spatial resolution,lens distortion, camera shake and object motion. This ...
Combined network analysis and molecular dynamics simulations study for characterization of prevalent somatic mutations in breast cancer: Sf3b1 case study
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2020)
Breast cancer has the highest incidence and mortality rates among women. The etiology of the disease has remained elusive because of complex interactions among various factors. The somatic mutations are one of such factors ...
The problems of common criteria evaluation for hospital information management systems in Turkey
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2019)
Hospital information management systems (HIMS) are essential tool for hospitals not only for the management of the hospital but also for improving healthcare quality and efficiency. The developed countries set national and ...
Neural network-based adaptive myoelectric signal classification via utilization of entropy history
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2017)
The surface electromyography (sEMG) signals emanating from the remnant forearm muscles of transradial amputees are eligible for controlling robotic prostheses to replace the functions of the lost hand. sEMG pattern recognition ...
Developing novel spectrum occupancy prediction and physical layer security techniques
(İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2020)
Wireless communication systems have pervaded every aspect of our lives; from financial transactions to health records, from entertainment to work, from education to travelling. This extensive usage of wireless devices is ...
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 ...
