In this presentation, conditions and explicit formulas for the realization of a relaxed fourth-order linear time-varying system as a cascade connection of two commutative first and third-order systems are given. The results are supported by an example.  

Nanotechnology is the science of controlling materials at the atomic and molecular levels. With the use of nanomaterials for diagnostic and therapeutic purposes, the field of molecular nanotechnology has emerged, enabling nanoelectronic biosensors and individu…

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…

Makine öğrenmesi teknikleri, hesaplama hızları, başarımları ve tam bilgiye sahip olunmayan durumlarda bile sunduğu çözümler sayesinde birçok mühendislik problemleri için vazgeçilmez bir araç haline gelmiştir. Tüm mühendislik alanlarında olduğu gibi, kablosuz i…

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…

Refrigeration and air-conditioning systems consume about 15% of global electricity, and 46% of energy used in household and commercial buildings belongs to heating, ventilation and air-conditioning (HVAC) systems. Vapor-compression technologies dominate the HV…

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…

This study presents a comparative evaluation of five widely adopted blockchain consensus algorithms—Proof of Work (PoW), Proof of Stake (PoS), Delegated Proof of Stake (DPoS), Practical Byzantine Fault Tolerance (PBFT), and Proof of Authority (PoA)—based on en…

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…
