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

Compact rectenna design for RF energy harvesting applications RF enerji hasatlama uygulamaları için kompakt doğrultuculu anten (rectenna) tasarımı

Göçen, Cem

ABSTRACTIn this study, a detailed literature study has been conducted about radio frequency energy harvesting systems, and two different RF energy harvesting system designs are presented operated two different bands. RF energy harvesting systems have been in our lives for more than fifty years. The number of studies carried out on these systems has increased, especially to meet the power requirements of low power consumption devices whose usage is growing with the developing technology in recent years. In the literature, RF energy harvesting systems have been generally designed to operate in t ...Daha fazlası

Design of arduino shield to record real-time electrocardiography signals Elektrokardiyografi sinyallerinin gerçek zamanlı kaydı için elektronik filtreli ardunio eklentisi tasarımı

Çağatay, Onur Doğanay

ABSTRACTIn this thesis, an Arduino extension board (shield) is designed to take theelectrocardiography (ECG) signals. Firstly, the positive and negative terminals of an ECG signal are selected to determine which input pins are connected to these terminals. User can select one of eight possible inputs for each terminal, which means the user can apply one of the possible 64 channel combinations to inputs of the design. Then a dedicated instrumental amplifier amplifies the signal. The voltagegain of the amplifier can be selectable among available options. The amplified ECG signal is filtered in a ...Daha fazlası
