This study examines the failure mechanisms of a three-phase AC induction electric motor with a closed body design, intended to provide IP protection, due to insufficient cooling under high-temperature conditions. Overheating at elevated temperatures adversely …
Many structures, machinery, equipment, heritages, also socio-cultural systems may be subjected to the unfavourable impact caused by various disaster risks, such as flooding, heavy snow, earthquakes, landslides, hurricanes etc. For prevention and reduction of d…
Bu çalışmanın hedefi, silis kumu (SK) ve Termik Santralinden elde edilen uçucu kül (UK) kullanılarak geopolimer harç üretmektir. Bu çalışmada uçucu külü aktive etmek için çimento yerine, aktivatör (Na2SiO3 ve NaOH) ve uçucu kül (UK) birleştirilip bağlayıcı mad…
Taşıyıcı sistemlerin deprem, rüzgar gibi etkiler altında dinamik analizinde serbest titreşim analizi önemli bir yer tutmaktadır. Dinamik yükler altında taşıyıcı sistemlerin serbest titreşim analizi sürekli veya ayrık kütleli hesap modelleri kullanılarak gerç…
One of the materials that are increasingly used today in various engineering applications is boron steels. Though boron steels draw attentions with their superior wear characteristics, studies on the tribological properties of these materials is quite limited …
This paper describes a laboratory application for the forecasting the dielectric properties, using an artificial neural network embedded in a microprocessor. The dielectric permittivity and loss factor of the insulation material were determined as a function o…
A universally applicable “optimal photobioreactor” design has yet to be established, as the success of such systems varies depending on the algal species used, environmental conditions, and intended applications. Meanwhile, the accelerating pace of climate cha…
The formation of architectural form is influenced by functional, economic, social, cultural, climatic, and environmental factors, along with construction and stability conditions. Stability is crucial in shaping form and ensuring durability against environment…
Gelişen teknoloji ve artmakta olan nüfus yoğunluğu sebebiyle enerji talebi gün geçtikçe artmaktadır. Artan enerji talebini karşılamak için gerilim seviyeleri yükseltilmekte, yeni iletim hatları inşa edilmekte, ya da var olan iletim hatları akım taşıma kapasite…
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 …
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…
Bu çalışmada yüksek aşınma direncine sahip Hardox 500 ve Hardox 600 çeliklerinin abrasiv aşınma dirençleri incelenmiştir. Her iki malzemeden 10 mm çapında ve 25 mm uzunluğunda numuneler hazırlanmıştır. Bu numunelerin aşınma davranışları pin-on disk test cihazı…
Bu çalışmada, yarı-katı işlem yöntemi ile Al-SiC kompozit malzemelerin sabit yük altında aşınma davranışları incelenmiştir. A356 matrise, 4 farklı miktarda (%5, %10, %15 ve %20) SiC ilave edilmiştir. Titreşimli tip değirmende bilyesiz olarak (30 dakika) karışt…
Bu çalışmada yüksek ticari saflıkta (%99,8) alüminyum ve çinko elementleri kullanılarak bir adet ikili Al-35Zn alaşımı üretildi. Alaşım elementlerinin ergitilmesinde orta frekanslı bir indüksiyon ocağı kullanıldı. Ergimiş durumdaki sıvı metal oda sıcaklığınd…
This paper describes innovative and novel trends on engineering education. Among these trends internet-based engineering laboratory with virtual and physical experiments, smart classes, 3G/4G technologies, and e-learning and m-learning facilities can be expres…
As widely known, construction on soft soils is generally problematic since the engineering properties of soft soils generally cannot meet the conditions required. Settlement, bearing capacity and seismic performance of the overlying structures is always questi…
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…
Few ancient structures inspire spiritual reverence and architectural awe like the Roman Pantheon. Designed as a temple and a cosmological instrument, the Pantheon depicts how Roman architects transformed daylight into a divine symbol. This paper examines the s…
Cross-laminated timber (CLT) has gained prominence in the construction sector in recent years. In addition to eliminating most of the known disadvantages of wood, providing advantages such as earthquake resistance, lightness, fast application, etc.; its effect…
