DIN 1.2344 sıcak iş takım çeliği; özel olarak içyapısı temizlenmiş, sünekliği ve tokluğu arttırılmış homojen mikroyapıya sahip, iyi ısıl kararlılığığa sahip olan yüksek ısıl şoklara dayanımlı bir çeliktir. Bu çelikler, ekstrüzyon kalıpları, dövme kalıpları, …
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…
Hydroxyapatite/polymer composites are promising materials for drug delivery applications. Studies focusing on the development of such composites are available in recent years, as using these materials as a carrier allows us to overcome the side affects of to…
In this study, in an effort to develop polymer matrix composite materials, especially to be employed as workbench and kitchen bench usage, powdered waste porcelain was used as a filler to form satisfactory mechanical properties together with Salvadora persica …
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…
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…
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…
Renewable energy can be produced by using kinetic energy of the flowing water such as rivers, ocean currents and tidal flows. The kinetic energy can be transformed to the power by hydrokinetic turbines. There are many different designs of hydrokinetic turbin…
In this study, thermodynamic analysis of a geothermal power-based district energy conversion system which produces electricity, hot water, heating and cooling are investigated. The energy produced from geothermal resource can be utilized to drive a double stag…
Because of the great earthquakes that have occured for centuries, many loss of lifes and goods have been experienced all over the world. Our country is located on active seismic zone. Many great earthquakes have also occurred in our country and have caused man…
Determination of Qualified personnel is one of the most basic tasks of the human resources department of enterprises. Increasing industrialization and population increase the alternatives at the point of finding suitable workers. This makes it difficult to ass…
Bilişsel radyo kullanılmayan ya da az kullanılan spektrum bantlarına dinamik olarak erişim olanağı sağlayan ve kullanıcılar arasında herhangi bir olumsuzluğa neden olmadan spektrum paylaşımını gerçekleştiren yazılım tabanlı bir teknolojidir. Kablosuz haberleşm…
