Many well-known material structures, such as metals, ceramics or polymers, cannot meet all the technological demands. For this reason, there is ongoing research into new materials with advanced features. A composite material is consisting of at least two phase…

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…

In this study, a PID controller with fractional order derivative filter (PIDFF) is designed for automatic voltage regulation (AVR) in power systems. In order to ensure maximum transient and steady state performance from the designed controller, the controller …

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…

Otel işletmelerinde çalışanların kişisel özellikleri bireysel ve örgütsel çıktılarını doğrudan etkilemektedir. Çalışanların işlerini kendi özelliklerine göre şekillendirmesi ve aynı zaman diliminde birden fazla iş yapma özelliklerinin olması iş performanslar…

This study develops the Political and Economic Vulnerability Score (PAVS), a composite index for assessing cross-country differences in macro-financial and institutional vulnerability. Drawing on publicly available World Bank data, the index combines 13 indica…

Synchronous Reluctance Motors (SRMs) are defined as reliable electric motors. Although the history of this type of motor dates back a very long time, their usage areas have started to increase with the developments in power electronics in recent years. While t…

The most fundamental role of the banking system is to direct funds into the real sector. In all country economies around the world, banks play an important role in transforming savings into investments by acting as a bridge between the financial sector and the…

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…

Elektromiyografi, kas aktivitesi sonucunda meydana gelen biyolojik işaretlerin ölçülmesine olanak sağlayan invaziv olmayan bir yöntemidir. Yüzey ve iğne elektromiyografisi olarak uygulama amacına göre iki şekilde kullanılmaktadır.  Bu çalışmada internet üzerin…

Evaluation of rock engineering properties is a significant phenomenon for mining, civil and geotechnical engineering disciplines. Uniaxial compressive strength is one of the most important engineering parameters and it is used to characterize rocks from the …

Oscillation theory for the solutions of Sturm-Liouville problems is one of the traditional trends in the qualitative theory of difierential equations. Its main goal is to establish su–cient conditions for the existence of oscillating solutions, to investigate…

It is well-known that the Sturm-Liouville type boundary value problems appears in solving many important problems in physics. For example, some problems of theory of elasticity in a half-strip ,the problems of theory of vibrations of an elastic cylinder redu…

This study presents the modelling of the pathological elements based memelements. More than forty years ago, Chua predicted the existence of memristor (memory+resistor) which is the fourth fundamental passive circuit element. In 2008, Hewlett Packard (HP) rese…

In this study, the experimental application of polymer electrolyte membrane fuel cell (PEM-FC) with dc-dc boost converter is realized for compact design of electric vehicle (eV). The PEM-FC is an electro-chemical device which combines hydrogen with oxygen to p…

In this study, we focused on to drive a compound DC motor with a Fuel-Cell and battery, which uses hydrogen as a fuel. A fuel cell can supply maximum 40V electric. In order to drive a DC motor, it needs 200Vdc. Therefore, a microcontroller controlled boost con…

Researchers attention on the optimization methods to solve several applications increases recently by the advances in the technological field. The Artificial Bee Colony algorithm that has been quite popular during the recent years is firstly used in this study…

The Designesart Collection was created as part of the master’s program in Furniture and Interior Design at the Instituto Politécnico de Castelo Branco’s Escola Superior de Artes Aplicadas, Portugal. It is a product series that values inherent Beira Baixa’s ter…

Religion and belief systems have emerged to address the fundamental human need for belief. Over time, religion has evolved and become an integral part of societal culture. Temples constructed by polytheistic beliefs to perform their religious rites and ceremon…

Pyrite is a mineral which has very low economic value although it is very common in the world. When the pyrite is concentrated together with the precious minerals, it produces a decrease in the grade and an increase in the smelting costs of the precious minera…
