ABSTRACTThis thesis includes design, implementation and polymer nanocomposite mixing application of chaotic system based robust delta robot. Blending fluids is a vital process while preparing coating materials. The most commonly used the coating materials are polymeric materials which need to be blended in non-Newtonian fluids. This process is very critical and harder to achieve a perfectly prepared coating material.To achieve superior blending performance, two different and independent chaotic systems were used to chaotify delta robot-based blender system. One of them was used for chaotificat ...Daha fazlası
ABSTRACTSevere Plastic Deformation (SPD), applying extreme force to alterate and refine the structures of materials permanently, have a huge potential to improve the mechanical and structural properties of materials superiously. ECAP is a kind of SPD techniques to produce submicron or nano sized grains in the material structure by applying stress to the sample passing through two angular intersected channels have the same diameters. ECAP has recently been becoming one of the most favourable candidate method in the production of nanostructured materials.One of the main objectives of this study ...Daha fazlası
Özet:Makine öğrenimi yöntemleri, bir mekanizmanın girdileri ve çıktıları arasında mevcut ancak belirsiz bir ilişkinin olduğu durumlarda öne çıkmaktadır. En yaygın beyin bozukluklarından biri olan epilepsi de böyle bir durumdur. Bu nedenle, makine öğrenme algoritmalarının öngörücü yetenekleri ile birlikte sinyal işleme tekniklerinin açıklayıcı gücünden yararlanmak, EEG kayıtlarından epileptik nöbetleri saptamak ve tahmin etmek için uygun bir yaklaşımdır. Bu çalışma, nöbetleri tespit etmek ve tahmin etmek için iki ayrı ancak uyumlu çerçeve sunar. İlk çerçeve, birkaç sınıflandırıcı ile nöbet akti ...Daha fazlası
Additive manufacturing is used today in different industries to produce prototypes and even final products. Additive manufacturing offers solutions for the fabrication of complex geometries and is preferred for manufacturing parts in a wide variety of applications. The fused filament fabrication (FFF) method is the additive manufacturing method with the most users worldwide. With the developing material science, it has been possible to produce composite structures and even metal products by going beyond the production of pure polymers in the FFF method. The mechanical properties of the materia ...Daha fazlası
SUMMARYThe interfacing compatibility of the matrix material with the filler material in composite materials is one of the most important factors affecting the performance of the composite. A wide variety of chemical methods are applied to increase the interfacial compatibility of the matrix material with the filler material. The most important of all is the surface modification technique, in which surface-active agents are used to reinforce the matrix-filler bond and where a chemical process is applied to the surface of the filler material.This technique is based on the chemical treatment of t ...Daha fazlası
