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…

Östenitik paslanmaz çelik malzemeler düşük ısıl iletkenlik ve yüksek korozyon direnci gibi özelliklerinden dolayı yaygın olarak kullanılmaktadır. Bu çalışmada AISI 304 ve AISI 316 L östenitik paslanmaz çelikler karbür kaplamalı kesici takımlar ile parmak freze…

Fuel cells can be considered as clean, efficient and economic devices for the next power generation. Flow configuration and operating conditions such as temperature, relative humidity and stoichiometric number are key factors for improving cell performance. …

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…

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…

The health need is undoubtedly an indispensable necessity for human life. When the literature is examined, it is seen that various health monitoring systems are developed by helping to meet the health need with technological improvements. Some of these studies…

With this work, automation levels of the railway systems will be described as explained in IEC 62290 standard, and then the relationship between these defined levels of Istanbul metro lines will be tried to be explained. In railway systems, the level of automa…

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…

The incidence of skin cancer is increasing. Early detection of cases of skin cancer is vital for treatment. Recently, computerized methods have been widely used in cancer diagnosis. These methods have important advantages such as no human error, short diagnosi…

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…

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…
