In this paper, a singular-feed circularly polarized (CP) metasurface antenna with broad impedance bandwidth is presented. The antenna consists of modified slots with a lattice of 3 × 3 square conductive patches. Modes are selected and excited by modified slot …

In this study, a single switch cascade DC/DC boost converter has been preferred instead of conventional cascade DC/DC boost converter to reduce cost and provide simple system control. High-performance controller design for DC/DC converters is the most importan…

Pink noise, which has a power spectral density that is inversely proportional to the frequency, is widely used for acoustic applications such as for testing audio equipment. Its generation from white noise requires such a system transfer function that it is no…

A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessa…

The log files that are continuously recorded are one of the most important information generated by web servers.Hadoop is an open source application platform that works on large amounts of data using hardware clusters. Web server logs are large-volume plain …

In this work, a new torque vectoring strategy is developed and the results are compared with those of existing controllers that are widely used for such applications in the existing literature. The objective of said strategy is to generate the corrective yaw m…

Failure Mode and Effects Analysis (FMEA) is a technique that evaluates and classifies the errors/risks that may occur at different stages in the enterprises according to their types and prioritizes the errors. Because it is an easy and effective technique to a…

Cellular phones are playing an important role in technological devices in today’s world. People start to use cellular phones at early ages. Even kids have their own cellular phones as a precaution for their security. However, researches evaluating long term …

The (9) and (12) compounds are optimized at B3LYP/6-31G(d,p) level in gas phase. The calculated bond length and bond angles are compared with experimental values. Also, the calculated vibrational frequencies are assignment for mentioned compounds according t…

Oscillators are one of the most important basic circuit blocks frequently used in electrical-electronics engineering applications. Among several types of the sinusoidal oscillators, quadrature oscillators are frequently used in communication circuits, control …

Asynchronous motors are the most preferred engines in the industry due to factors such as their stable speed, economic and operational safety. Recently, asynchronous motors have been used as generators in the power generation sector and especially in wind turb…

Bu çalışma, transformatörlerde alçak gerilim (AG) tijlerinin kararmasına yol açan aşırı ısınma sorunlarını ve bu sorunların çözümünü ele almaktadır. Transformatörler, elektrik enerjisini alçak gerilimden yüksek gerilime veya tam tersine çevirerek, enerjinin uz…

This article discusses an algorithm for fuzzy control of the technological mode of a reactor unit using fuzzy production models of logical inference and fuzzified measurement information from the control object, discusses the methodology of a computational exp…

The next generation aircraft will be operated first with hybrid technology and then with purely electric technology, just like in the automobile industry. More electric aircraft concepts today have brought about a reorganization of the generation, transmission…

African administrations suffer from slow and cumbersome administrative procedures. Administrative rigidity usually leads to impasse and some citizens do not hesitate to circumvent the administrative formalism by trying to bribe agents of the state or by playin…

Design and usage of Unmanned Aerial Vehicles (UAV) especially for military purposes has been rapidly increasing in recent years due to their capability to endure long flight durations without needing a crew and due to their low cost compared with the conventio…

Deep learning is a machine learning sub-field that uses deep neural networks. Instead of customized algorithms for each study in this field, it is aimed to cover the wider data set of solutions based on learning the data. Deep learning is a promising approach …

With the rapid development of technology and the importance of electronic devices in our lives, electromagnetic waves produced by various sources and the related electromagnetic pollution concepts have become an important issue that directly affects the nature…
