High temperature superconductors (HTSs) have been widely used in magnetic bearing systems, magnetically levitated transportation systems (Maglev), superconducting motors, etc. due to their stable levitation properties. Although the studies on Maglev systems ha…

Ball and beam system is an experimental set for control system design that the position of the ball on a beam is changed with respect to the reference direction by changing the angle of the beam. The PID controller is applied to this problem. The performance o…

Solar energy from renewable energy sources can be used for different purposes. The most common areas of use are electricity generation and preparation of hot water. While photovoltaic (PV) modules are used for direct electricity production, commercial vacuum…

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…

Elektrik sistemlerinin arızasız ve güvenli bir şekilde çalışabilmesi, akım ve gerilim gibi devre büyüklüklerin 50 Hz frekansta ve sinüsoidal formda olmasına bağlıdır. Bununla birlikte bir çok nedenlerden dolayı bu temel büyüklükler sinüsoidal özelliklerini k…

Since the design of the first high rise building, the “Home Insurance Building” erected in Chicago in 1884-1885 only with 11 floors, new technologies encourage the designers to build taller and slender buildings penetrating through the sky. In the history, h…

Optimal reactive power flow and economic power dispatch is very important in power systems. Optimal reactive power flow provides minimum active power loss and economic power dispatch provides minimum active power generation cost in power systems. This study pr…

In last years, the use of alternative energy sources such as solar energy has become even more important because of environmental problems, especially the rapid depletion of fossil energy resources. There are works done for this purpose and solar energy applic…

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…

The COVID-19 pandemic has necessitated the development of rapid, accurate, and automated diagnostic tools to assist healthcare professionals in patient screening and management. This comprehensive study presents a detailed comparative analysis of ten state-of-…

Palmprint recognition (PR) has garnered significant interest due to its distinctive characteristics and potential applications as a robust and secure biometric authentication (BA) method across various domains. This paper introduces a novel approach to enhance…

The Head of Revenue Administration (HRA) in Turkey imposes the obligation to use new generation payment recording devices (NG PRDs) at fuel stations. The pump and the cash register were separate units in old payment systems, and communication was provided via …

İnsanlar arasında ilk iletişim yöntemlerinden biri olan oyun, her geçen gün gelişen teknolojiyle birlikte oyunlaştırma kavramının temellerini oluşturmuştur. Teknolojik cihazların yaygınlaşması ve belirli platformlardaki oyun süreçlerinin kolaylaşması ile oyunl…

In cloud environments, especially database manageability is a particularly important quality. This necessitates the development of database self-management technologies that have been explored in the past decade. A separate problem is the absolute scale of clo…

Elektronik kartlarda meydana gelen yüksek ısı üretimi, kart üzerindeki bileşenlerin çalışma performansını ve kullanım ömrünü etkileyen önemli bir parametredir. Bu nedenle cihazların mekanik tasarımları yapılırken soğutmayı sağlamaya yönelik çalışmalar yapılmal…

The successful estimation of future electricity consumption has a crucial importance in the energy planning. Because, in order to meet rising energy demand, policy makers should formulate electricity supply policies and make critical decisions and develop ne…

Eşikleme yöntemleri kenar belirleme, bölütleme ve kümeleme yaklaşımlarında sıklıkla kullanılmaktadır. Söz konusu teknikler yardımıyla renk kanallarından çeşitli sayıda kümeler elde edilebilir. Ancak, hangi yaklaşımın daha başarılı olduğu konusu belirsizliğini …

The aim of this study is to determine instantaneous irradiance and annual percentile sunlit time on the available rooftop floor area of Technical and Social Science Vocational School at Usak University by simulation using open source software. The building of …

Predictive maintenance (PdM) enhances industrial operational efficiency by facilitating timely detection of equipment failures using machine learning models developed from historical maintenance data.  Real-world industrial datasets frequently exhibit signific…

Seismic data is a critical source for examining and understanding subsurface structures. It is used in various fields such as oil exploration, geological research, mining, underground infrastructure planning, environmental monitoring, and conservation. The ana…
