Development of cast aluminum metal matrix composites by additional processes Döküm alüminyum metal matriks kompozitlerinin ilave proseslerle geliştirilmesi

Aybarç, Uğur

ABSTRACTIt is seen that materials used traditionally today are insufficient to meet market expectations. For this reason, the interest on composite material increases day by day. The role of composite materials has become important in sectors, such as especially in automotive and aerospace industries, where a final product weight is of importance.This thesis consists of four application parts. In the first part, a detailed literature review on aluminum metal matrix composites was discussed. In the second part, the appropriate stirring method was searched for the production of aluminum metal ma ...Daha fazlası

Design and robot operating system based control of a modular robot manipulator Modüler robot manipülatör tasarımı ve robot işletim sistemi tabanlı kontrolü

Kahveci, Aytaç

ABSTRACTIn this thesis, a new design of the modular robot manipulator and its control with Robot Operating System is presented. The modules are designed to have an adjustable twist angle, which enables to create different robot manipulator configurations. Kinematic synthesis on the gripper module is conducted and structural parameters of the gripper is determined. Axis sets on the modules are determined by Denavit-Hartenberg method. Inverse and forward kinematic analysis and singularity analysis are performed. Numerical inverse kinematic solver is proposed for modular robot manipulators with m ...Daha fazlası

Antimicrobial effect of cold atmospheric plasma to pegdma hydrogel with cell encapsulation tests Soğuk atmosferik plazma ile pegdma hidrojeline antimikrobiyal etki kazandırılması ve hücre çalışmalarının yapılması

Yıldırım, Çağla

ABSTRACTSterilization techniques that are used for polymer based 3D scaffolds are uneffective and changes polymer chemical and mechanical properties. Cold atmospheric plasma is well-known antimicrobial agent that is the fourth state of matter. In this study, antimicrobial effect, cold atmospheric plasma effects on cell viability and polymer structure were investigated as an alternative method for sterilization techniques used in polymer sterilization. Firstly, the antimicrobial effect of cold atmospheric plasma on both bacteria E. coli and S. aureus was determined. Two different antimicrobial ...Daha fazlası

Investigation of wearable motion capture system towards biomechanical modelling Biyomekanik modellemeye yönelik giyilebilir hareket yakalama sisteminin araştırılması

Köse, Hakkı

Özet:Hareket Yakalama (MOCAP), biyomedikal mühendisliği alanında implant, ergonomi ve fizyoterapi tasarımında biyomekanik modeller oluştururken önemli bir adımdır. MOCAP sistemleri çıktı olarak kinematik veri sağlar. Biyomekanik modeller bu çıktıyı insan vücudunun eklemlerindeki hareket aralığını (ROM) ölçerek kinetik çıktı üretmek için bir girdi olarak kullanır. Biyo-aslına uygun modelleme için doğru günlük yaşam verileri gereklidir. Burada veriyi biyomekanik bir modelleme yazılımına beslemek için Smartsuit Pro'ya (Rokoko, Kopenhag, Danimarka) işaretleyici olmayan giyilebilir yeni bir MOCAP s ...Daha fazlası

Preparation and characterization of carbon-based nanofluids Karbon bazlı nanoakışkanların hazırlanması ve karakterizasyonu

Fidan-Aslan, Tuğçe

ABSTRACTNanofluids are produced by the addition of nano-sized particles to the base fluid in order to increase the thermal conductivity of heat transfer fluids. Preparation of stable nanofluids with high thermal conductivity is a very complex process and their usage in heat transfer applications are related to many important parameters from the stability of nanofluids to their viscosity. Optimization of these parameters is essential for the practical use of nanofluids. The objectives of this study are to successfully preparecarbon-based nanofluids while investigating the stability mechanisms a ...Daha fazlası

The effect of antibacterial photodynamic therapy on healthy fibroblast and keratinocyte cells Antibakteriyel fotodinamik terapinin sağlıklı fibroblast ve keratinosit hücreleri üzerindeki etkisi

GÜLCE KADIKÖYLÜ

ABSTRACTAntibacterial photodynamic therapy is a treatment that occurs in the presence of light, photosensitizer and oxygen. The photosensitizer reacts with the molecular oxygen in the environment when it is stimulated by light at the appropriate wavelength, causing reactive oxygen species at the end. Reactive oxygen species show high cytotoxic effects on cells and cause necrosis or apoptosis. In recent years, the resistance of bacteria to antibiotics has caused infection treatments to become more difficult. This situation has become a threat to human and animal health. Therefore, antibacterial ...Daha fazlası

Estimation of annual energy production of coupled vertical-axis wind turbines in a semi-complex terrain Eşli çalışan düşey eksenli rüzgar türbinlerinin yarı karmaşık bir sahadaki yıllık enerji üretiminin değerlendirilmesi

Başer, Ferhat Cem Ferhat Cem

ABSTRACTRecent research shows that the vertical-axis wind turbines (VAWTs) can provide up to 6 - 9 times more power generation in the same footprint area when they are sited in proper configurations in contrast to horizontal-axis wind turbines (HAWT). In order to site wind turbines in a field, it is necessary to do a wind resource assessment (WRA). This assessment provide important inputs for the placement, sizing and design detailing of the wind farm. In addition to the correct determination of the site, it is also critical to place the wind turbines in the most efficient way. When the necess ...Daha fazlası
