In this study, the effect of using a mixture of butanol and diesel fuel in a small diesel engine on engine performance and exhaust emissions is modeled. A comparison has been made with artificial neural networks, which is an up-to-date method, and multiple l…

In this study, two different welding methods as TIG and TIG Pulse are used for joining 304 series stainless steel sheets having 2 mm thickness. In preparation of welded specimens were used three different welding currents ranging from 70 A to 110 A by rise o…

Tek Fazlı Şebeke Kalkışlı Sabit Mıknatıslı Senkron motorlar (TF-ŞKSM) günümüz endüstrisinde kullanılan standart indüksiyon motorlarına göre özellikle küçük boyutlarda daha yüksek verimlilik sunabilmektedirler. Verimliliğin artması çevre üzerindeki olumsuz et…

Bu çalışmada, gezici robotun verilen sahayı tam gezinmesi problemi Çinli Postacı Problemine benzetilerek çözülmeye çalışılmış, çözümün eşleşme adımına Yapay Arı Kolonisi Algoritması ile çözüm bulunmaya çalışılmıştır. Haritalanmış sahanın grafının tek derecel…

A novel continues plasma reactor with rotating electrodes was designed and constructed to investigate methane decomposition to hydrogen and solid carbon. This new reactor structure causes stable operation. Hydrogen is main part of gaseous products which cont…

2018 yılı verilerine göre 7,6 milyarı geçen dünya nüfusu her geçen gün artmaya devam etmekte ve bu artışla birlikte insanların ihtiyaçları da her geçen gün artmaktadır. Enerji ihtiyacı ise temel gereksinimlerin başında yer almaktadır. Enerji geçmişte ve gele…

Bu çalışma; havadan havaya bir atık ısı geri kazanım uygulamasında ısıl performansı etkileyen faktörlerin optimum değerlerinin araştırılması üzerinedir. Sistemde ısı transferini gerçekleştirmek üzere polimer malzemeden imal edilmiş çapraz akışlı plakalı ısı de…

Deep learning allows computational models of multiple processing layers to learn and represent data with multiple levels of abstraction mimicking how the brain perceives and understands multimodal information, thus implicitly capturing intricate structures of …

The new material type is ‘cryogels’, which have important potential in biotechnology applications. Cryogels can be obtained from natural or synthetic polymers. It is seen that cryogens prepared from natural polymers become a preferred material group for tissue…

Nowadays, in the field of industry and commerce, heavy loads have to be removed by various methods and moved from one place to another. Mobile cranes in order to overcome these tasks are in common use. One of the problems that prevent the safe and long-lasting…

Structural health monitoring is an interdisciplinary field that enables early detection of undesirable situations such as damage or defects that occur in the structure or its components thanks to its ability to self-diagnosis. It is possible to use safer engin…

The effects of climate change in the world are observed to have significant effects on different environmental variables. Therefore, changes in climate parameters should be examined and analyzed. These changes can be determined by parametric and non-parametr…

Bu çalışmada balıklara doğal ve rahat bir yaşam alanı oluşturmak için akıllı bir akvaryum tasarımının yapılması amaçlanmıştır. Akvaryumun tasarımı için kullanılan elektronik bileşenlerin kontrolü Arduino mikrodenetleyicisi ile gerçekleştirilmiştir. Akvaryum iç…

Several test suites have been developed to test the statistical properties of random numbers generated from pseudotrue random number generators. Some of these are Crypt-X, Diehard, FIPS 140, NIST 800-22 AIS31 test suites. In this study, web based application o…

In the present study, energy and exergy analyses of a solar powered absorption refrigeration system are corried out by terms of the first and second laws of thermodynamics. NH3-H2O fluid couple is used in the system. The analyses are performed with the help of…

This study presents the investigation of thorium utilization in an ADS with Lead-Bismuth Eutectic (LBE) target. To effectively burn thorium, the ThO2 fuel rods cylindrically prepared, and cladded with SiC, are mixed with 233UO2 at volumetric ratio of 1%. These…

3D printing filling structures at prototyping and design stage are increasingly important issue for products with complicated shapes. The objective of the present study is to investigate 3D printing filling structures effect on mechanical properties and surfac…

Bu çalışmada doğalgaz borularının kaynaklanabilirliğinin tespiti için API 5L X52 kalite 21,3 mm (1/2 inç) yarıçapında 2,8 mm et kalınlığına sahip borular 100 mm boyutlarında kesilmiş ve kaynak ağzı açılmıştır. Kaynak ağzı açılmış olan numuneler oksigaz, elektr…

Post-quantum cryptographic standardization is complete for the algorithms that matter most, yet adoption across financial infrastructure remains uneven and, in critical segments, largely absent. This paper argues that migration is no longer a research question…

Healthcare fraud, waste, and abuse (FWA) are among the most significant drivers of financial inefficiency in healthcare systems worldwide, with estimates suggesting they contribute to as much as 10% of total healthcare expenditures. In the United States, these…
