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…

Cellular phones are playing an important role in technological devices in today’s world. People start to use cellular phones at early ages. Even kids have their own cellular phones as a precaution for their security. However, researches evaluating long term …

In recent years, significant improvements have been made in face transplants as well as organ transplants operations. It is also important to improve the adaptation process and quality of life of the patient after the transplant as well as the successful compl…

Hardox çelikler mükemmel aşınma direncine sahip, ultra yüksek mukavemetli, kayma ve darbe aşınmasına karşı dayanıklı martensitik çeliklerdir. Madencilik ve inşaat mühendisliği endüstrisinde ağır makineler ana uygulama alanıdır. Bu çalışmada, Hardox 400 çeliğ…

Recently, the basis properties and eigenfunction expansions in various function spaces of the eigenfunction of the regular boundary value problems with spectral parameter in the boundary conditions have been investigated by many mathematicans. However in diff…

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…

Bu çalışmada, frekans çözünürlüğünün (yankı çözünürlüğünün) R-MUSIC (Root-MUSIC, Çoklu Sinyal Sınıflandırma) ve ESPRIT (Rotasyonel Değişmezlik Tekniği ile İşaret Parametrelerinin Kestirimi) yöntemleri kullanılarak nasıl değiştiği incelenmiştir. Bu yöntemler,…

In this paper, signal recognition system is proposed for classification of soil types and buried object by using feature extraction and artificial neural networks. Using GprMax simulation program, 300 GPR A scan signals were obtained for different ground plane…

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…

2020 yılına kadar büyük veri gereksinimi ile birlikte kullanıcı sayısının hızlı bir şekilde artmaktadır. Yeni nesil hücresel iletişim teknolojilerinin bu veri trafiği ile beraber daha yüksek veri hızlarını desteklemesi beklenmektedir. Yaklaşan 5.nesil (5th Gen…

Several statistical analyses of the Pisarenko harmonic decomposition (PHD) method for frequency estimation of a single real sinusoid in noise have been carried out in the literature. However, all of the analyses consider the phase of the sinusoid as a constant…

Instantaneous estimation of the frequency of a real sinusoid in noise from a small number of data samples is an important problem in the signal processing area. Several frequency estimators are proposed for this problem in the literature. In this paper, some o…

In this work, Intralube E with 0.38 % C press-ready mix powders were pressed with 550 MPa pressure and sintered 25 min at 1120 °C. Samples were coated electrochemically with nano diamond (ND) reinforced nickel to study the effect of nano composite coating on c…

Kanser, insan ölümlerine sebep olan hastalıklar arasında ikinci sırada gelmektedir. Günümüzde insanların kansere yakalanma oranları giderek artmaktadır. Kanser; kötü beslenme, sigara ve alkol kullanımı, uzun süre güneş ışığına maruz kalma gibi birçok nedenle o…

Diabetes is a chronic disease affecting millions worldwide, necessitating early and accurate diagnosis for effective management. Traditional diagnostic methods, while reliable, often struggle with efficiency and early-stage detection. Deep learning has emerged…

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…

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…

Energy dissipaters used in open channels are devices designed to reduce the flow velocity and allow water to pass downstream without harming water structures and environment. In this study the effect of energy dissipaters on energy loss is investigated depende…

Open channel flow is defined as fluid flow with a free surface open to the atmosphere. One of the main sources of resistance in open channel flow is the roughness of channel bed. The roughness of channel base and side walls must be considered seperately invest…
