In recent years, nanofluids, the dispersion of nanoparticles with sizes less than 100 nm in base fluids, have been attracted the interest of many researchers due to their capability of enhancing thermophysical properties. In this review paper, experimental s…

Evaluation of rock engineering properties is a significant phenomenon for mining, civil and geotechnical engineering disciplines. Uniaxial compressive strength is one of the most important engineering parameters and it is used to characterize rocks from the …

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 problem of discharging of the water in a rectangular tank from the orifice with square crosssection was investigated experimentally and numerically. Time evolution of the water level, obtained experimentally by using image processing techni…

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…

Solar energy from renewable energy sources can be used for different purposes. The most common areas of use are electricity generation and preparation of hot water. While photovoltaic (PV) modules are used for direct electricity production, commercial vacuum…

The aim of this study is to investigate the production conditions of silver nanoparticles in the presence of AgNO3 with the cytoplasmic fluid of white rot fungi Coriolus versicolor. In the study, parameters such as pH, AgNO3 concentration and cytoplasmic fluid…

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…

Çarpan jetler, iyi bir ısı transferi performansı sağlamaları nedeniyle genellikle sanayide elektronik ekipmanların ısıl problemlerini çözmek için kullanılırlar. Bu çalışmada, tek bir hava jeti akışı kullanılarak bir tarafı açık, üç tarafı kapalıdikdörtgensel…

In last years, the use of alternative energy sources such as solar energy has become even more important because of environmental problems, especially the rapid depletion of fossil energy resources. There are works done for this purpose and solar energy applic…

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…

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…

We developed a series of financial social media sentiment analysis models starting with PyFin-Sentiment, a recent state-of-the-art domain-specific large language model for the financial domain. We focused on label accuracy and improvements in the quality and q…

Word embedings are intense vector representations of words. They capture the semantic order between words. In our study, we propose a new method for classifying text by author, using word embeds and author vector space. Using each author's books, we trained th…

In this study, mathematical modeling of an ohmic heating system has been done, firstly. Then, two different control approaches, PID and fuzzy logic control, have been considered to control of mathematically modeled ohmic heating system. An optimal PID controll…

Biyomalzemeler, canlı doku işlevlerinin yerine getirilmesi amacıyla kullanılan doğal ya da sentetik malzeme türleridir. Biyomalzemeler, biyolojik sistemlerle etkileşim halinde olan ve tıbbi cihaz amacıyla kullanılan cansız malzeme olarak adlandırılırlar. Malze…

The present study investigates the heat transfer characteristics of swirling coaxial confined impinging turbulent air jets. Experimental range covers different values of dimensionless nozzle-to-plate distance (H / D = 0.5, 1 and 2) and dimensionless flowrate…

In many engineering applications such as aerospace, automotive and telecommunications, icing leads to mechanical and socio-economic problems such as efficiency reduction, decreased power transmission, security threat, material damage and energy waste. Theref…

In this study, mixed convection heat transfer and fluid flow in a three-dimensional horizontal duct with three different geometries of cavity were investigated numerically. Air flows in a square duct which is heated by a cavity with triangular, a rectangular a…
