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
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
ABSTRACTUnmanned Aerial Vehicles (UAVs) are commonly propeller-driven and intended towards low-speed applications. The challenges on the field demand cost-efficient, high-speed and longer range applications of micro-scaled jet engines which can be applied both ‘loiter’ and ‘fly-fast’ modes. The micro-turbojet applications on the field have shorter ranges because of higher rates of fuel consumption. On the other hand, turbofan engines instead of turbojets are limited due to the price and complexity problems in micro-scales. In order to cope with this problem and meet the demand on the field, an ...Daha fazlası
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
ABSTRACTDiabetes Mellitus (DM) is a chronic disease that progresses rapidly. Today, thenumber of diabetic patients is increasing day by day, but treatment methods arebeginning to be inadequate due to the insufficient time, financial deficiencies andother restrictions. Diabetes education and treatment are very important for thediabetic to survive. Diabetes treatment is practiced in many areas of life from thenutrition habits to the social life activities. In terms of the course of diabetestreatment, it is necessary for the self-management of the patient to follow thediabetes education and appli ...Daha fazlası
ABSTRACTCities that have a history as a capital or an important trade center, has its own complex structure. If the historical city center was functionalized as a commercial district, it has been experienced social, cultural, environmental and economical subjects throughout centuries. This situation creates strong impacts as newly created contexts likewise political, public and architectural. These contexts generally not thought together, but they should be analyzed and investigated together for a sustainable future for the historical city centers. As a historical city center, Kemeralti-Izmir ...Daha fazlası
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
