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…

Bu çalışmada, non-lineer ve dengesiz yükün bulunduğu güç sisteminde aktif filtre kullanılarak harmonik distorsiyonun değeri düşürülmüştür. Pasif harmonik filtrelerin aksine, modern aktif harmonik filtreler, güç faktörü düzeltme, gerilim regülasyonunu saglama…

In this study, the experimental application of polymer electrolyte membrane fuel cell (PEM-FC) with dc-dc boost converter is realized for compact design of electric vehicle (eV). The PEM-FC is an electro-chemical device which combines hydrogen with oxygen to p…

Bir manyetik mikromanipülatör farklı uygulamalar için gerekli manyetik kuvveti üretme kabiliyetine sahip olarak geliştirilebilir ve mikron boyutlu parçacıkları manipüle edebilir. Bu çalışma etkin ve otomatik mikro-parçacık manipülasyonu için geribeslemeli kont…

Parasitic capacitance has adverse effect on capacitive micromachined ultrasonic transducer (CMUT) performance. Reduction of parasitic capacitance, therefore, is essential for high performance CMUT device. Isolation layer between two electrodes of CMUT is one o…

Artificial lighting is an important part of global electricity consumption. At office buildings, the energy consumed by artificial lighting can reach up to 40% of total energy consumption. This work is being done to find solutions to such problems with energy …

Ricania japonica (Melichar, 1898) (Homoptera: Ricaniidaee) is a harmful insect species. It is spreading in the Eastern Black Sea coastline from Artvin- Kemalpaşa to Ordu - Perşembe. Since 2006, R.japonica has been continuing to suffer the loss of all vegetab…

Post-quantum cryptographic standardization is complete for the algorithms that matter most, yet adoption across financial infrastructure remains uneven and, in critical segments, largely absent. This paper argues that migration is no longer a research question…

Maritime vessel detection in satellite images address real time issues such as maritime security, illegal fishing and environmental monitoring, which require efficient tracking of vessels in large scale. Maritime vessel detection is challenged by limited annot…

This study employs a supervised learning approach for the Stock Portfolio Selection (SPS) problem. The proposed approach solves three problems defined in the literature review: the narrow period selection problem, the proper objective selection problem, and th…

Haptic devices are used in a variety of virtual reality applications in order to allow user interaction with virtual objects. These devices transfer user comments such as rotations, transitions or deformations to the virtual environment and also transfer any r…

In recent years, the financial sector has been considerably developed, especially in electronic banking. As individual users in the financial sector use e-banking and e-finance systems, the concept of loyalty in the banking sector has shifted from traditional …

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…

Social networks are formed from interactions of peoples. Measuring the degree of those relationships requires interpreting connectivity of vertices and extracting information from it. Generally individuals form smaller sub-communities in those networks. Identi…

This paper describes a laboratory application for the forecasting the dielectric properties, using an artificial neural network embedded in a microprocessor. The dielectric permittivity and loss factor of the insulation material were determined as a function o…

Solar photovoltaic (PV) systems are widely adopted for sustainable energy production; however, physical defects such as glass breakage significantly reduce panel efficiency and system output. In this study, a real-world case analysis was conducted on a 1003 kW…
