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…
Taguchi’s robust parameter design focuses on reducing the system variability caused by the noise factors. The results obtained under unrealistic assumptions about the noises may mislead the practitioners when it comes to improving quality in robust design. For…
Scientific progress is an ongoing process and humans always have new ideas for new inventions. Although, scientific process is cumulative, you must invent the tire before inventing the car. Currently, mankind has past that point and looking towards to new chal…
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…
In the present study, the effects of cutting parameters on surface roughness were investigated in order to determine the optimum machining conditions for the hot work tool steel (155 HB), which is an important part of the mold industry. For this purpose, the m…
The aim of this study is to forecast installed wind power which is a one of the renewable energy resources in Turkey for the year of 2017 based on artificial neural network method using the normalized last ten-year data. An artificial neural network has been c…
Hastaneler yüksek maliyetlere ve belirsizliklere sahip; aynı zamanda sınırlı kaynaklarla mümkün olan en kaliteli hizmeti sağlama amacıyla yönetilen sistemlerdir. Ameliyathaneler de bu sistemin en önemli gelir ve gider kaynağını oluşturmaktadır. Ameliyathane çi…
This paper presents a different approach for the optimal active power flow solution in multi-terminal AC-DC systems to minimize total active power generation cost. System constraints for all of the control and state variables of both AC and DC systems are also…
The hub location problem deals with locating hub facilities and allocating non-hub nodes to hub. Hub location problem is classified as p-hub median problem, p-hub center problem, hub covering problem and hub location problem with fixed cost in the literature. …
Optimal reactive power flow and economic power dispatch is very important in power systems. Optimal reactive power flow provides minimum active power loss and economic power dispatch provides minimum active power generation cost in power systems. This study pr…
Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is a pest species that has become an important problem for plant breeders all over the world. 2017 in Kemalpasa (Artvin, Turkey) has also been identified and added to our list of alien invasive species. In a…
Because today’s architecture is characterized by various concepts and numerous designs instead of an architectural style, it is heavily described by the identity of the architect. However, according to the d-gene pool theory of Karina Moraes Zarzar, this ident…
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…
Modern education has a systemic – evolutionary character and is one of the factors of a sustainable civilization process. Global transformations of education are aimed at creating not only the information society, but also “a planetary civilization with sustai…
The dimensions of discrimination in Turkey was not discussed much. Furthermore, the policy made with it is not paid attention. The ideological tools and mass media also can be responsible for this issue. The emergence of discrimination should be a matter of …
Diyarbakır buğday alanlarında 2016-2017 yıllarında buğday bitkisinin köklerinde kökbiti, Smynthurodes betae Hemiptera: Aphididae) saptanmıştır. Bitkinin köklerinde koloni oluşturarak, köklerden bitki özsuyunu emerek beslenmesi sonucu bitkinin gelişmesi geril…
Mimarlık; toplumsal, ekonomik, teknolojik boyutlarının ötesinde temelde, mekân tasarlama ve nesneleri biçimlendirme eylemi gerçekleştirir. Mimarların biçimlendirme sürecine nasıl başladığı veya hangi yöntemleri kullandığı büyük bir araştırma konusudur. Bu çalı…
This study evaluates the performance of Faster R-CNN and YOLOv7 object detectors for dynamic ship detection in maritime applications. Both algorithms are tested under challenging conditions, including poor image quality due to cloud and dust obscuration, varyi…
