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 …

This study is related with numerical modeling of a Francis turbine draft tube. In order to reveal this relationship, a real Francis turbine model test results are used as inputs of the computational fluid dynamics (CFD) study. Firstly, the flow in divergent ch…

Evolution of EU road transport emission standards indicates that the limits have been reduced more than 90% in the last decades. However, nowadays, the urban populations in many developed countries are still suffering from urban transport sourced emissions. On…

Asynchronous motors are the most preferred engines in the industry due to factors such as their stable speed, economic and operational safety. Recently, asynchronous motors have been used as generators in the power generation sector and especially in wind turb…

Since the design of the first high rise building, the “Home Insurance Building” erected in Chicago in 1884-1885 only with 11 floors, new technologies encourage the designers to build taller and slender buildings penetrating through the sky. In the history, h…

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…

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…

Timber structures are used as building elements in ancient times due to the lightness and durability. Formwork material of reinforced concrete structures are also made of wood. Although timber is widely used in industry, it has been limited research in liter…

Bu çalışmada Yapay Arı Koloni optimizasyon algoritmalarının üç varyantı sürü robotların hedef bulma probleminde kullanılmıştır. Yapay arı kolonisi optimizasyon algoritmalarının Unity 3D ortamında simülasyonunu gerçekleştiren yazılım geliştirilmiştir. Sürü ro…

In this study, natural colored (dark gray) wool and white angora fibers were firstly hand-spun and then hand knitted fabrics were produced from these yarns. Then, mass per unit area, air permeability and the hand of the fabrics were compared statistically. I…

Complexity in the behavior of asphalt binders are further escalated with geopolymer (fly ash and the alkali liquid) modification thus, making it difficult to predict the performance of the binder accurately. This study employs artificial neural network model…

The study presents the tribological behavior of epoxy matrix composites containing two different fillers. Hybrid composites were produced with casting method. The composites contains fillers with different particle sizes (<90µm and in the range of 150-300 µm) …

Contact pressure is very critical for wear test. In order to make true wear experiment, counter body, surface, wear load, surface roughness, and the hardness of materials should be selected correctly. Maximum contact pressure forms at hertz point. In this stud…

Many communication protocols are being used and standardized for the Internet of Things (IOT) infrastructure. At the forefront of the features expected from the protocols used is the efficient operation of a limited bandwidth and low bandwidth electronic devic…

The log files that are continuously recorded are one of the most important information generated by web servers.Hadoop is an open source application platform that works on large amounts of data using hardware clusters. Web server logs are large-volume plain …

The major part of freight transportation in Turkey is conducted by highway, the increase in the number of trucks and other heavy vehicles, as well as legislations allowing an increase in axle load that lead to deterioration such as rutting in flexible road pav…

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…

The sun's rays, which are our source of life, give us pleasure to enjoy in the winter and spring, but in the summer, the steep and scorching rays disturb us all. For this reason, it is observed that on average, 52% of the cooling load needed in the calculation…

In the world, constructions are mostly reinforced concrete framed structures with infill walls. Different reinforcement studies have been carried out on these existing structures in order to ensure the safety of life and property without heavy damage because o…
