In order to understand brain function, diagnose disorders and develop precise treatments, the detection of dopamine using electrochemical devices is important. The detection of dopamine using electrochemical devices continues to be investigated, as evidenced by studies in the literature in recent years. This is because it helps to unravel the complexity of brain function, facilitate the diagnosis of neurological disorders and enable the development of precise treatments. These devices are important in neuroscience and medicine.
Today, with the developing telecommunications and electronic technologies for civilian and military purposes, electromagnetic (EM) applications have a wide usage area, including different frequency ranges, such as radar, wireless information transfer, and medical technologies, as well as radio frequencies. However, the broad use of these technologies causes EM wave pollution, so they have a devastating effect not only on the working functionalities of electronic devices but also on human health. Therefore, the need to develop these technologies to prevent EM wave pollution is increasing daily. ...Daha fazlası
Additive Manufacturing (AM) is a manufacturing method that pushes the limits of imagination and eliminates the question of whether complex industrial products can be produced that cannot be obtained with traditional manufacturing methods. In this study, microstructure and mechanical properties of maraging steels produced by DMLS method and aged in different durations (6 and 9 hours) and atmospheres (Air, N2 and N2/H2) were investigated. When the SEM images were examined, it was ob-served that the molten pool boundaries did not disappear completely but became blur-red with increasing temperatur ...Daha fazlası
Fouling is the accumulation of undesired particles on heat transfer surfaces which affects the heat transfer performance of a heat exchanger negatively. The accumulation of these particles prevents heat from being transformed through the heat exchangers by generating a fouling layer-like insulation. The main aim of the thesis is to investigate the machine learning algorithms to classify and predict the fouling status of PHE used in combi-boilers, to generate the background of the predictive maintenance, besides investigating the fouling effect on PHEs in terms of heat transfer and energy consu ...Daha fazlası
Alzheimer's disease continues to be a serious public health issue. Alzheimer's disease affects generally old people, and it is a neurological disorder. The most significant sign of Alzheimer's disease is memory loss, which becomes worse over time. Therefore, early identification of Alzheimer's illness can aid in diseased getting the proper care. One of the aims of this thesis is to automate the early detection of Alzheimer's disease and create a self-improving system by utilising previous experiences each time it is detected automatically. In this way, the bad effects of the disease due to the ...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

Teknolojinin ve teorik bilginin gelişmesiyle son 20 yıldır günlük hayatımızın her
alanında olduğu gibi sağlık alanında da yapay zekâ (YZ)'nın uygulanması giderek
artmaktadır. Özellikle koronavirüs (COVID-19) ve iskemik inme gibi toplum sağlığını
tehdit eden hastalıkların YZ ile tespit edilmesi sağlık çalışanların iş yüklerini
hafifleterek daha doğru tanı sağlamaktadır. Bu hastalıkların tespit edilmesinin yanında
medikal görüntü üzerinden hastalık bölgelerinin bölütlenmesi, sağlık çalışanlarına
tedavide yardımcı olabilecek bilgi sağlamaktadır. Bununla birlikte medikal görüntü
üzerinden b ...Daha fazlası
Public institutions need movable and immovable property, resource and altitude rights
in order to perform their duties and services imposed on them by the constitution and
laws. It is possible for public institutions to obtain these needs by renting or purchasing
them by making a contract like all other real and legal legal persons. However, if the
person who owns the properties or rights required by the Public Institutions does not
want to make a contract, or if the price cannot be agreed upon, it will lead to the
disruption or non-fulfillment of the duties and services required to be f ...Daha fazlası
A colorimetric analysis is a technique that measures the properties of the substance using color changes in chemical or biochemical analysis. It is vital in analysing biological, medical, and environmental samples in many fields, such as the food, medicine, cosmetics, and paint industries. Colorimetric analysis requires correct measurement and calibration techniques to obtain accurate results.
At the core of our growing societies, energy supply stands as one of the major concerns today, and it will be an inevitable challenge for our near future. As the nations are looking to find solutions for the transition from fossil fuels – depleting at a high rate – to alternative energy sources, solar energy through PV cells is getting attention as an affordable and easily implemented option especially for power supply in commercial and residential buildings.
