İnsanın nasıl temiz içme suyu ve yaşam hakkı, en demokratik hakkıysa, soluduğu havanın da temiz ve sağlıklı olması en demokratik hakkıdır. İç ortamlar, insanların zamanlarının yaklaşık %80-90'ını geçirdiği kreşler, konutlar, okullar, resmi binalar, kapalı sp…
Elastomer materials can be jointed using various connection types with metallic parts. Removable connections (with screws, nuts, etc.), adhesive and vulcanization methods are some of them. In this work, it is investigated that how joint between one type of e…
Bu çalışmada Yapay Arı Koloni optimizasyon algoritmalarının üç varyantı sürü robotların hedef bulma probleminde kullanılmıştır. Yapay arı kolonisi optimizasyon algoritmalarının Unity 3D ortamında simülasyonunu gerçekleştiren yazılım geliştirilmiştir. Sürü ro…
Bu çalışmada, frekans çözünürlüğünün (yankı çözünürlüğünün) R-MUSIC (Root-MUSIC, Çoklu Sinyal Sınıflandırma) ve ESPRIT (Rotasyonel Değişmezlik Tekniği ile İşaret Parametrelerinin Kestirimi) yöntemleri kullanılarak nasıl değiştiği incelenmiştir. Bu yöntemler,…
With development of technology, humanity has entered to age of information. In this era, there is big development has been existed on software’s. With these technological developments, artificial intelligence and virtual reality subjects are one of the most …
Bu çalışmanın amacı, Al2O3 ve SiO2 kaynağı olarak seramik üretiminde kullanılan 5 farklı kaolenin jeopolimer üretiminde kullanılabilirliğinin araştırılmasıdır. Bu amaçla beraber öğütülen kaolen-NaOH karışımları su ile birleştirilip preslenmiştir. Taze jeopol…
Titanium and titanium alloys are suitable for a variety of applications, with their low density, high strength and high corrosion resistance. Despite strong mechanical and corrosive qualities, titanium use is restricted by its weak friction and wear characteri…
Environmental engineering is an engineering discipline that is concerned with protecting people from adverse environmental impacts such as pollution, as well as improving environmental quality. Environmental engineers work to improve recycling, waste disposal,…
Optimal operation of the power systems is very important. In this paper, a new approach for both the economic active power flow and active power loss minimization in multi-terminal HVDC systems is proposed. In the proposed optimization approach, system constra…
In this study, combined thermal radiation and natural convection heat transfer problem are investigated in glass and plastic covered flat solar collector. The bottom plate that absorbs the sunlight and the ambient temperature are kept constant. Solar collector…
In this study it was aimed to determine the influence of frozen storage at -18 ₒC during 0, 5, 10, 15, 30 and 45 days on physical and sensorial properties of partially baked gluten free bread (GFB). Potato starch, corn starch, corn flour, chickpea flour and ri…
Stroke in cerebrovascular diseases occurs as a result of the breakdown of the blood flow to the brain. In this study, our objective is to investigate the genotype and allele distributions of ACE I /D, LTA C804A, HPA-1(a/b) ve Beta fibrinojen 455 G-A gene polym…
The reuse of wastewater reduces both the consumption of freshwater resources and minimizes the environmental impact of discharged wastewater. Biological treatment technologies have been utilized in wastewater reclamation for over a century. Membrane Bioreactor…
Molecular interactions have been a hot topic in chemistry because of their importance in different processes from biological activities [1]. Quantum dots with strong and easily tunable luminescence and high emission quantum yields have become well-established …
One of the most consumed energy sources today is fossil-based fuels. While the reserve of these fuels is declining, it continues to be the main cause of environmental pollution. Due to the influence of environmental factors and increases in fuel costs has acce…
We are at a time when electronic systems are structured in a manner similar to the human brain.The memristor, a neuromorphic circuit designed by Chua in 1971, is a modeling of synaptic learning and associative learning. Neuromorphic circuit elements and memris…
Construction and elevator sectors are growing rapidly all over the world with the technology that has developed in recent years as complementary to each other. Elevator industry, which is developping collaterally in Turkey with the world, is getting a more and…
Bitumen polymer modification has a long history. However, most of the polymers currently used as additive in bitumen are not economically attractive. Thus, employing recycled materials in flexible highway instead of virgin ones has become a fundamental case …
Nowadays, as the population increase, various construction projects are made on soils which engineering properties are not suitable. Many stabilization methods are used in order to prevent deformations and loss of bearing capacity on such soils. However, most …
