ZnO nanopowders were synthesized via microwave assisted hydrothermal method at different precursor solution molarities. For this, the aqueous solutions of zinc aceatate dihydrate and sodium hydroxide were prepared at different molarity as precursor materials…
Fossil fuels used by traditional internal combustion vehicles today are quite damaging to environment. Because of these fuels, global warming has reached a very dangerous point. However, fossil fuels are gradually depleting. Therefore, it is inevitable that el…
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…
A universally applicable “optimal photobioreactor” design has yet to be established, as the success of such systems varies depending on the algal species used, environmental conditions, and intended applications. Meanwhile, the accelerating pace of climate cha…
Nowadays, nature-inspired structural colorization takes increasing attention due to its exceptional optical properties. One-dimensional (1-D) photonic crystals are new kind of optical materials which can be used to obtain structural colorization. In recent yea…
This study includes the design of quadratic cascade DC/DC boost converter with PI controller. Two or more cascade boost converters have been used to increase system efficiency. Advantages of the proposed converter compared to the conventional boost converter a…
Fotovoltaik (FV) sistemler birkaç W’dan, MW’a kadar ölçeklendirilebilmesi gibi özelliklerinden dolayı en çok yaygınlaşan yenilenebilir enerji kaynağı türüdür. Bu enerji kaynağından en yüksek oranda yararlanılabilmesi maksimum güç noktasını izleyen (MPPT) dönüş…
Aluminum based metal matrix composites are frequently used in automotive, aircraft, space, automotive, agricultural and building industries due to their easy shaping, good heat and electrical conductivity, low density, high strength and toughness. In these com…
This study aims to examine the feasibility and impact of conducting laboratory experiments, a fundamental component of electrical and electronics engineering education, on a virtual reality (VR)-based platform. The innovative platform, named "VR-EE Lab," provi…
The unlimited nature of consumption and needs contrasts with the scarcity of usable resources, necessitating the optimal use of available resources. Alongside the careful protection of the environment and human health, it is crucial to meet needs with maximum …
In this study, mathematical modeling of an ohmic heating system has been done, firstly. Then, two different control approaches, PID and fuzzy logic control, have been considered to control of mathematically modeled ohmic heating system. An optimal PID controll…
Asenkron motorlar, endüstrideki en yaygın kullanılan motorlardır. Çok avantajlı bir yapıda olduklarından üretim hatlarının her noktasında bulunurlar. Bu motorların arızalarını hızlı ve kolay bir şekilde tespit etmek arzu edilir. Bu makalede, asenkron motorları…
This work is about a system that generates electrical energy with the heat energy from the evaporator of the air conditioner and cools the environment. It is applicable to all types of air conditioner and air conditioning systems. It generates electrical energ…
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…
Coils are electrical-electronic circuit elements and they are obtained by winding conductive wires on top of one another on a core or space, when electrical current pass through the coils they bring a magnetic field around them. The electromotive force (emf) t…
In recent years, significant improvements have been made in face transplants as well as organ transplants operations. It is also important to improve the adaptation process and quality of life of the patient after the transplant as well as the successful compl…
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…
This study presents a Hybrid Digital-Physical Risk Management Framework designed to enhance urban climate resilience through the integration of Industry 4.0 technologies. By combining real-time IoT sensor networks, AI-based predictive analytics, and blockchain…
Microalgae are recognized as environmentally sustainable and biologically renewable resources for the production of high-value products such as biomass, biofuels, dietary supplements, and pharmaceuticals. However, their large-scale cultivation is highly sensit…
