In the last decade, deep learning in general and Convolutional Neural Networks (CNN) have achieved a human level and outstanding performance in almost all computer-based systems such as classification(text, images, and videos). Building an efficient CNN archit…

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 effects nano-SiO2 and nano-Al2O3 on cement mortars were experimentally studied. The percentage of nano-powders were used as 1%, 3% and 5% into the material. Different types of analysis were used to nano-powder’s impact on the cement mortars.…

Titanium and its alloys are increasingly used in aerospace, automotive and biomedical industries because of their high strength, excellent corrosion, wear resistance and a wide range of mechanical properties. Materials with superior properties are needed in …

In this study, a thermoelectric generator (TEG) system is designed for the generation of electricity from solar energy. A temperature difference between surfaces of TEG must be achieved for electricity generation. Heating is provided by a solar-powered two-p…

Bu çalışmada, ağırlıkça %0.1, %0.3 ve %0.5 oranında grafen nanotabaka (GNT) takviyeli alüminyum (Al) matrisli kompozitler toz metalurjisi metoduyla üretilmiştir. Üretilen kompozitlerin deneysel yoğunluğu, çekme dayanımı, aşınma oranısırasıyla; Arşimet yoğunl…

Gelişen teknoloji ve artan nüfusun etkisiyle enerji tüketimi giderek artmaktadır ve bu durum tüm dünyada olduğu gibi ülkemizde de önemli bir problem olarak karşımıza çıkmaktadır. Fosil enerji kaynakları gün geçtikçe azalmaktadır ve bu nedenle araştırmacılar …

Many well-known material structures, such as metals, ceramics or polymers, cannot meet all the technological demands. For this reason, there is ongoing research into new materials with advanced features. A composite material is consisting of at least two phase…

In our country, industrial investments and manufacturing capacity increase day by day. It is possible to enhance standard and quality of product, increase manufacturing capacity, constitute production line with less energy consumption by adapting developing te…

There are various numerical methods for solving many problems in mathematical physics. The differential transform method (DTM) is one of the numerical methods for solving ordinary and partial differential equations. The concept of the differential transform…

This article discusses an algorithm for fuzzy control of the technological mode of a reactor unit using fuzzy production models of logical inference and fuzzified measurement information from the control object, discusses the methodology of a computational exp…

Generally, it is limited to obtain all kinds of data for determining of variables which distributed points in any area. Estimates are made from this data for unsampled locations. Thus, the spatial properties of an examined variable are defined all over the are…

In this study, a classification problem is discussed to predict whether individuals' annual income levels are above $50,000. The UCI Adult Income Dataset, which is derived from the 1994 US Census (Census) data and is widely used in the field of machine learnin…

In this study, diabetes prediction was conducted using XGBoost, Support Vector Machines (SVM), and a Multilayer Artificial Neural Network (ANN). Attributes that cannot be biologically ‘0’ (e.g. glucose, BMI) were first marked as NaN. After filling the missing …

Experimental design methods used in optimization of engineering problems and processes in many industrial fields have been shown to be applicable in road superstructures within this study. Using the special purpose statistical experiment design program, opti…

Soft wheat flour is the most important raw material in the production of cookies. But because of gluten intolerance of celiac patients they should not consume gluten containing cookies made from wheat flour. Therefore in this study it was aimed to form a suita…

For a successful thermal performance, the right choice and design of the thermal management materials used in LED die-moulding, cooler and soldered parts is a critical engineering problem. Because they are affected by heat emitted from the pn junction in the L…

Sleep disorders such as insomnia, sleep bruxism, narcolepsy, and sleep-disordered breathing have different sleep quality parameters such as cyclic alternating pattern phases and A subtype phases. This study aims to analyze and predict the A phase subtypes from…

The utilization of renewable energy sources is being enlarged daily to meet the escalating energy needs around the world. Solar energy, like other renewable energy sources, occupies an important place in the energy generation sector. Since it is important to i…
