Gnss Tabanlı Zamanlama ve Senkronizasyon
(Fen Bilimleri Enstitüsü, 2022)
Time is considered as a concept expressing a process and a criterion used. It is
known that atomic clock units are the most sensitive units in this field and are used
in satellite systems on the basis of obtaining time ...
Kompozit Tabanlı Alan Etkili Transistör Tasarımı ve Dokunsal Algılama Uygulaması
(Fen Bilimleri Enstitüsü, 2022)
Studies on the design and production of flexible field-effect transistors (FET) using nanocomposite structures were carried out within the scope of this thesis. The design, on which field effects occur on it, is similar ...
Sarmal Antenlerin Boyutlarının Küçültülmesi
(Fen Bilimleri Enstitüsü, 2017)
Helical antennas are generally an easy to design type of antenna. These antenna
types, which are designed for wire bending, can have circular polarization, so that their
polarization can be represented by two linear ...
5G Mobil Uygulamaları İçin Çift Bantlı MIMO Anten Tasarımı
(Fen Bilimleri Enstitüsü, 2022)
This thesis consists of the design and production of single-element and MIMO antennas in 28 GHz - 38 GHz frequency bands for 5G mobile applications. First of all, rectangular patch antenna was designed with a slot. This ...
Baskı Devre Kartlarında Lehim Hatası Denetimi
(Fen Bilimleri Enstitüsü, 2022-07)
In the assembly process of printed circuit boards (PCBs), most of the errors are caused by solder joints in surface mount devices (SMDs). We propose using beta-Variational Autoencoder (beta-VAE) that learns from normal ...
Metro ve Hafif Raylı Ulaşım Araçları için Süperkapasitör Depolamalı Frenleme Enerjisi Geri Kazanımı Sistemi Geliştirilmesi
(Fen Bilimleri Enstitüsü, 2022-06-15)
In this thesis study, development, laboratory setup and realization of a energy storage system based on supercapacitor which aims to recover braking energy in metro and light rail vehicles is presented. In this context, ...
Derin Öğrenme ile Plankton Sınıflandırması
(Fen Bilimleri Enstitüsü, 2022-03)
Plankton which is at the bottom of the food chain in the aquatic ecosystem and is responsible for producing approximately half of the oxygen in the atmosphere, is one of the most important components of life on earth. ...
Çok Kullanıcılı Yoğun Çok Girişli Çok Çıkışlı Sistemler İçin Sıkıştırılmış Algılama Tabanlı Kanal Kestirimi
(Fen Bilimleri Enstitüsü, 2018)
Spatial multiplexing advantages of Massive MIMO systems which have an important part of the future generation cellular communication systems come to the forefront thanks to large number of antennas at base station. Base ...
Bir İnsansız Hava Aracı Baz İstasyonunun Uçuş Dinamikleri Kısıtları Altında Konuşlandırılması
(Fen Bilimleri Enstitüsü, 2019)
Within the scope of this thesis, the efficient placement of UAV Base Stations which have gained importance in 5G and beyond communication studies are examined. The efficient placement of UAV Base Stations in the field is ...
Görüş Hattı Ortamında Çok Kullanıcı İçin Hüzme Yönlendirme
(Fen Bilimleri Enstitüsü, 2019)
Due to the increasing number of communication devices used today and the increase in the required data size and data transfer rate for each device, the existing communication infrastructures are inadequate and therefore ...
