With the rapid development of technology, cellular networks can no longer meet the
demands of wireless networks. Communication systems need to be updated to ensure
that every user equipment (UE) receives accurate and efficient service. Cell-free (CF)
networks offer advantages over cellular networks, such as more flexible resource
allocation, higher capacity, better coverage and lower interference. The deployment of
multiple access points (APs) and flexible allocation of resources leads to higher
network performance and efficiency. In addition, in CF networks, users can
communicate with ...Daha fazlası
İnme, günümüzde dünyada önde gelen ölüm nedenlerinden biridir. İnme geçiren hastaların tedavisi ve hayatta kalması için acil ve kesin tanı çok önemlidir. İskemik inmenin tanı ve tedavisi çoğunlukla manyetik rezonans görüntülemeye (MR) dayanmaktadır. Bu çalışmanın amacı, 2 boyutlu MR görüntüleri kullanarak U şeklinde bir evrişimsel sinir ağı mimarisi (CNN) oluşturarak iskemik inme lezyonunu bölütlemek ve çeşitli kayıp fonksiyonları kullanarak çalışmanın kayıp sonuçlarını, zar benzerlik katsayısını (DSC), hassasiyetini ve özgünlüğünü değerlendirmektir. Oluşturulan modeli eğitmek, doğrulamak ve t ...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
Dünya nüfusunun 2025 yılında 8.5 milyara, 2050 yılında ise 9.7 milyara ulaşacağı
tahmin edilmektedir. Bahsedilen nüfus artışından kaynaklı gelecekte arazinin daha
yoğun kullanılacağı öngörülmektedir. Bu sebeple sınırlı ve yenilenemeyen arazinin
yönetimi bir zorunluluktur. Söz konusu arazinin yönetiminden bahsederken,
bütünleşik parçası durumundaki taşınmazların (ör. Bina, parsel) ve bu taşınmazlara
ilişkin mevzuatın (ör. Yasa, yönetmelik) yönetimi de planlanması gereken diğer
hususlardandır.

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
Duplex steels are materials that contain ferrite and austenite phases in their structure, have high resistance to corrosion, and also show improved mechanical values. While the austenite in its structure provides general corrosion resistance and ductility, ferrite provides resistance to stress corrosion cracking and mechanical strength. Duplex steels have widespread use, especially in shipping and petrochemistry. The current production method of duplex steels, which are in demand with a wide usage area, is generally argon oxygen decarburization furnaces (AOD). In addition to the production met ...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.
Cellulose is the most abundant organic polymer on earth. It is naturally regenerated by forests and cotton plantations with a speed of 10 billion metric tons per year regularly. Not only its natural reproduction makes it ecologically beneficial but also its biological degradability makes cellulose an ‘eco-friendly material’. Applications of cellulose is limited due to its insolubility in water. Contrarily, its water-soluble derivatives, especially cellulose ethers, are found in nearly all the products we are using in our daily life.
Although cellulose is the main raw material for producing ce ...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

Millions of people worldwide suffer from diabetes and diseases caused by diabetes. As a result of the statistical studies carried out by the World Health Organization (WHO), the number of people suffering from diabetes was 108 million in 1980, then it was increased to 422 million in 2014. Diabetes is increasing rapidly, particularly in underdeveloped and developing countries and it was predicted that 1.5 million people died because of it only in 2019 (WHO, 2021).
Photodynamic therapy (PDT) is a non-invasive therapy that induces photochemical reactions for treating many diseases including cancer using the advantages of light. It is based on the interaction of light at a specific wavelength and light-sensitive chemical which does not have dark toxicity. Thus, PDT is an anticancer therapeutic modality yielding cancer cell death. As with other anticancer therapies, some drawbacks reduce or limit the efficacy of PDT. To eliminate the disadvantages resulting in increased efficacy of PDT, it is combined with other anticancer treatment methods. Together use of ...Daha fazlası
The aim of this thesis was to develop a wearable tele-physiotherapy device that addresses the remote elbow joint rehabilitation. The developed device consists of a wearable exoskeleton equipped with servo motor, joint angle sensor, EMG sensor, battery and Wi-Fi module. By connecting with the Android mobile application, it enables real-time monitoring of EMG data and programming of personalized exercise programs. The device offers convenience and comfort to patients by eliminating the need for face-to-face physiotherapy sessions and aims to reduce treatment costs and treatment time.
