Monitoring and management of storage and material consumption processes in silo systems. In this study, a CAN BUS-based sensor network was developed for the control of silo systems, the filling and discharging of materials into silos and the protection of mate…
Bilişsel radyo kullanılmayan ya da az kullanılan spektrum bantlarına dinamik olarak erişim olanağı sağlayan ve kullanıcılar arasında herhangi bir olumsuzluğa neden olmadan spektrum paylaşımını gerçekleştiren yazılım tabanlı bir teknolojidir. Kablosuz haberleşm…
In the fifth generation (5G), the traditional restrictions that limit the capacity of wireless communication must be overcome. Non-orthogonal multiple access (NOMA) is a promising solution capable of overcoming these constraints to meet the requirements of 5…
The monitoring of emissions caused by congested road traffic requires the deployment of a complex measurement system. The use of Wireless Sensor Networks (WSN) can be very useful. In this work we propose the architecture of sensors (devices) which are envisage…
İnternette yaygın veri kullanımı ve kapasitesi her geçen gün hızla artmaktadır. Bu nedenle, bu verilerin aktarımı veya iletimi sırasında veri güvenliği önem arz etmektedir. Dolayısıyla, birçok veri şifreleme algoritmaları kullanılmaktadır. Literatürde en yaygı…
İlk olarak 1999 yılında RFID teknolojisinin kullanımının önerildiği bir sunumda kullanılan Nesnelerin İnterneti kavramı (IoT); cihazların kendi aralarında konuştuğu (veri iletişimi yaptığı, bilgi topladığı, toplanan bilgiler ile karar verdiği) bir ağ yapısı …
Complexity in the behavior of asphalt binders are further escalated with geopolymer (fly ash and the alkali liquid) modification thus, making it difficult to predict the performance of the binder accurately. This study employs artificial neural network model…
Gelişen bilgisayar ve iletişim teknolojileri sonucunda güvenlik önemli bir konu haline gelmiştir. Güvenlik açıkları yetkilendirme, veri bütünlüğü sağlama, ağ güvenliği gibi sistemin çalışmasında etkili kısım veya kısımlarda olabilmektedir. Bir sistemin güven…
Bu çalışmada, frekans çözünürlüğünün (yankı çözünürlüğünün) R-MUSIC (Root-MUSIC, Çoklu Sinyal Sınıflandırma) ve ESPRIT (Rotasyonel Değişmezlik Tekniği ile İşaret Parametrelerinin Kestirimi) yöntemleri kullanılarak nasıl değiştiği incelenmiştir. Bu yöntemler,…
Structural health monitoring allows the status of structures or components to be assessed using sensors. This method is widely used in the evaluation of the state of engineering structures, especially aviation and space engineering. Sensors used in structural …
Bu çalışmada, robotik uygulamalarda yaygın bir şekilde kullanılan kapasitif rotary enkoder anlatılacaktır. Kapasitif rotary enkoderler hem açısal pozisyon hem de açısal hız ölçmede kullanılmaktadır. Enkoder temel olarak 3 ana parçadan oluşmaktadır: 1. komple i…
In this study, the effect of using a mixture of butanol and diesel fuel in a small diesel engine on engine performance and exhaust emissions is modeled. A comparison has been made with artificial neural networks, which is an up-to-date method, and multiple l…
With today's developing technology, learning applications reach more people within shorter time. This development of technology closely affects mobile technology. These developments in mobile technology are applied to make learning more effective. Mobile learn…
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…
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 …
Pansharpening, which is transferring the spatial content of a high-resolution panchromatic (PAN) band into a lowerresolution multispectral (MS) image to produce a spatially enhanced MS image, has always been one of the hottest topics of image processing. Nume…
Structural health monitoring is an interdisciplinary field that it is possible to identify defects in the structure or components of the structure at an early stage. The sensors used in structural health monitoring are called the piezoelectric wafer active sen…
Over the past decade, gold nanoparticles (AuNPs) have stimulated great interest in various types of sensors because they possess many attractive properties such as optical, electronic and chemical features [1]. In order to gain more intrinsic properties and …
Many communication protocols are being used and standardized for the Internet of Things (IOT) infrastructure. At the forefront of the features expected from the protocols used is the efficient operation of a limited bandwidth and low bandwidth electronic devic…
