Günümüzde, birçok araştırmacı optimizasyon problemleri çözen algoritmaları geliştirme eğilimindedir. Gerçek dünya problemleri ise genelde birden çok amaca sahip oldukları için çok amaçlı optimizasyon problemleri üzerine geliştirilen algoritmalar trend olmuştur…

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 …

In the phases of hydrological model calibration, the impact of control parameters of optimization algorithms on the related fitness (cost) function (reaching the global solution correctly and expeditiously) is rather essential. These control parameters’ dynami…

Differential evolution algorithm (DEA) is one featured kind of population based evolutionary algorithms. Although it is stated in previous studies that the algorithm is more sensitive to the crossover rate, it is tried out in this study whether DEA depends on …

One of the most well-known and easy-to-design converter of DC-DC converters is DC-DC Boost converter. DC-DC boost converters are widely utilized in industrial applications. Therefore, output voltage regulation of the boost converter is a popular issue that res…

The U-shaped assembly line balancing (UALB) problem has been extensively investigated in the existing academic literature. However, only a limited number of studies consider the uncertainty in the assembly lines. In this research, a robust formulation is devel…

Streptomyces is a genus of Gram-positive bacteria that has a filamentous form similar to fungi. Streptomyces produces bioactive secondary metabolites, such as antifungals, antivirals, antitumorals and various antibiotics (Procópio et al., 2012). The aim of thi…

The design of experiments is a highly effective offline quality improvement method to optimize the existing and new processes or products. In the literature, standard experimental situations have been paid a lot of attention. In a number of non-standard experi…

A central composite design is a good choice for a spherical design region while providing high-quality predictions over the entire spherical design region. However, this design requires design variable settings outside the range of the design variables in the …

In the manufacturing sector, as in other sectors, it is very important to be able to calculate the cost of the product and therefore to work towards reducing the cost. When calculating the cost of the product, perhaps one of the most important items is the cos…

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…

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…

Ağır metal kirliliği dünya çapında ciddi boyutlara gelmiş bir sorundur. Günümüz endüstriyel toplumunda, toksik kimyasallara ve metallere maruz kalmaktan kaçınmanın bir yolu bulunmamaktadır. Çevrenin önemli bir bölümü olan tarım toprakları bu olgunun bir parças…

Geriye dönük adım akışı, ısı depolama kaplarının iç ve dış akışında veya güç dönüştürme sistemlerinin toplayıcıları gibi birçok cihazda önemli olup akışın karmaşık yapısı nedeniyle önemli geometrik modellerden biri olarak göze çarpmaktadır. Bu çalışmada, dikey…

Gaz türbini motorları, yakıcılar, ısıtma ve soğutma sistemleri gibi birçok mühendislik uygulamasında geriye dönük adım akışı nedeniyle ayrılma ve yeniden birleşme bölgeleri meydana gelmektedir. Bu bölgelerin kontrolü, ısı ve kütle transferi miktarını artırmak …

In this study, the effects nano-SiO2 and nano-Al2O3 on cement mortars were experimentally studied. The percentage of nano-powders were used as 1%, 3% and 5% into the material. Different types of analysis were used to nano-powder’s impact on the cement mortars.…

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…

Furniture has a large share in all endstirisinde in the World and Turkey. People demand for furniture products is increasing day by day. Furniture manufacturers are curious about which furniture products are most demanded by customers. Although it is possible …

There are many factors that affect students' motivation to learn. Number of friends, friendship satisfaction and communication skills are some of the important factors. In scientific studies, friendship and peer rejection have unique effects on academic achiev…

The popularity of wireless communication is increasing day by day. This has led to the fact that data transfers via GSM have reached very high levels. Data transfers via GSM, which are continuously growing, increase the density of data traffic, thus necessitat…
