In this paper, the Ku-band rectangular microstrip patch antenna (RMPA) is intended to operate in the dual-band for satellite communication (SATCOM). The antenna which is obtained for dual-band by utilizing a U-slot and vertical slits on RMPA is fed with a micr…

In this study, it is aimed to design C pattern array microstrip antenna for C Band (4 to 8 GHz), X Band (8 to 12 GHz) and Ku Band (12 GHz to 18 GHz). The proposed geometry was fed by coaxial probe. Optimum antenna was designed with Artificial Neural Network …

In this paper, a singular-feed circularly polarized (CP) metasurface antenna with broad impedance bandwidth is presented. The antenna consists of modified slots with a lattice of 3 × 3 square conductive patches. Modes are selected and excited by modified slot …

The U-shaped assembly line balancing (UALB) problem has been extensively investigated in the existing academic literature. However, only a limited number of studies consider the uncertainty in the assembly lines. In this research, a robust formulation is devel…

Bu çalışma, sonbaharda ekilen ve kıraçta yetiştirilen %50 Macar fiği ve %50 buğday karışımının Haziran ortasından Temmuz sonuna kadar 7 kez 1 hafta arayla biçiminin besin madde içerikleri, in vitro kuru madde sindirilebilirlikleri, rölatif yem değeri (RYD) v…

This study was conducted to assess the effects of 5 types of water: Ozonated, Chlorinated, Celestite Stone-treated, Natural Spring Waters and PinResin-treated water on performance, oxidative stress and carcass parameters in Japanese quail. A total of 150, 3-…

In this paper, signal recognition system is proposed for classification of soil types and buried object by using feature extraction and artificial neural networks. Using GprMax simulation program, 300 GPR A scan signals were obtained for different ground plane…

With this work, automation levels of the railway systems will be described as explained in IEC 62290 standard, and then the relationship between these defined levels of Istanbul metro lines will be tried to be explained. In railway systems, the level of automa…

Analysis of faults in synchronous generators are so important to protect the generators and the power systems. In this paper, double line-to-ground fault analysis in unloaded synchronous generator is presented. Apart from the similar studies in the literature,…

Handwritten Signature Recognition (HSR) is a vital task in document authentication and verification systems. This paper proposes a novel approach for offline HSR leveraging pre-trained Convolutional Neural Network (CNN) models. CNNs have demonstrated remarkabl…

Gelişen teknoloji ve artmakta olan nüfus yoğunluğu sebebiyle enerji talebi gün geçtikçe artmaktadır. Artan enerji talebini karşılamak için gerilim seviyeleri yükseltilmekte, yeni iletim hatları inşa edilmekte, ya da var olan iletim hatları akım taşıma kapasite…

Chronically, the Nigerian pharmaceutical arena has witnessed a series of scandals, perhaps unprecedented level of unethical behaviors, cruelty or of a kind. These events have seriously shaken people’s belief. In general, such activities have left a black-hole …

In this paper we presents an application of deep learning techniques to recognize handwritten source code characters. Although there are many works on the handwritten character recognition (HCR) problem, very few works have been done about the offline handwrit…

Tek Fazlı Şebeke Kalkışlı Sabit Mıknatıslı Senkron motorlar (TF-ŞKSM) günümüz endüstrisinde kullanılan standart indüksiyon motorlarına göre özellikle küçük boyutlarda daha yüksek verimlilik sunabilmektedirler. Verimliliğin artması çevre üzerindeki olumsuz et…

Bu çalışma, Sinüzoidal Darbe Genişlik Modülasyonu (SPWM) tekniği kullanılarak çok alanlı simülasyon ve model tabanlı tasarım için bir blok diyagram ortamı olan MATLAB/SIMULINK platformunda MOSFET H köprüsü kullanılarak gerçekleştirdiğimiz asenkron motor sürücü…

Complex-valued artificial neural network (CVANN) has been developed to process data with complex numbers directly. In a CVANN the weights, threshold, inputs and outputs are all complex numbers. The convergence of the CVANN back propagation algorithm depending …

As the diversity of land and climate conditions in Azerbaijan is practical for the cultivation of a number of agricultural plants it also provides wide opportunities for the reproduction of pests in such areas. During the mass reproduction such pests cause sub…

Polycarbazole (PAAC) and poly (thiophene) (PTH) are both highly stable polymers. But the conductivity of (PAAC) is much lower than PTH. When polycarbazole and polythiophene alternative copolymers are synthesized, it is aimed to increase the conductivity of PAA…
