Generating captions and text descriptions of images will enable visually and hearing impaired extended accessibility to the real-world, thus reducing their social isolation, and improving their well-being, employability, and education experience. This thesis presents significant advancements in algorithmic approaches for generating captions and text descriptions. These enhancements are pivotal in processing and interpreting both image and audio data. The focus on algorithmic innovation ensures that the platform is not only efficient but also adaptable to various types of visual and auditory in ...Daha fazlası
The recent increase in life expectancy and changing living conditions have led to a
rise in developments regarding implants, particularly in orthopedic implants. It is
important to note that this statement is based on objective evidence and not
subjective evaluations. Despite these advances, issues with metallic implants such as
Ti, Ti alloy, Co-Cr alloy, and stainless steel (AISI 316L), which are currently
preferred, persist. There are several limitations to implant materials, including
corrosion due to the physiological environment, bacterial infection, and biofilm
formation. Although ...Daha fazlası
Mathematical models have been devised to comprehend and scrutinize biological neurons' structure and behavioural patterns. In order to assist in the utilization and visualization of these mathematical models for computations, simulations have been designed. In this thesis study, a simulator has been developed to be educational and to require no coding skills. It is intended to have a simple, understandable, and straightforward interface. This simulator includes simple interface pages where users can manually input parameters to be used in the models, and it also includes readymade experiments ...Daha fazlası
This thesis focuses on design and development of a robot manipulator with dexterous forceps for single-incision laparoscopic surgery. Integrating the robotic capabilities into laparoscopy instruments, the study aims to increase precision and reduce limitations such as mobility constraints. Main objective of the thesis is to develop a robotic articulating laparoscopy instrument. In light of the first trials, it is seen that the dexterity and robotic control advantages are promising while the trocar's mobility constraint limits the workspace of the robotic laparoscopy forceps. An alternative sur ...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
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
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.

In this study, CFD abilities to handle Darrieus turbine simulation were assessed and validated in light of related experimental and numerical studies. Simulation methodology is based on two-dimensional modeling of a double NACA 0018 bladed, straight blade Darrieus turbine. Modeling approach, meshing procedure, and solution parameters are mentioned and discussed in details. ANSYS fluent 18.2 is used to carry out all simulations. Experimental test’s data from literature [11] are implemented in context of results verification, also, Courant number and y plus analyses were provided. Due to the sim ...Daha fazlası
Monolitik zirkonyum restorasyonlar, mükemmel mekanik özellikleri, biyouyumluluk ve estetiği ile bilinir. Ancak, düşük sıcaklık bozulmasına (LTD) eğilimlidirler. LTD, su veya su buharı varlığında 100 santigrat derecenin altındaki sıcaklıklarda zirkonyumun bozulmasına karşılık gelir. Metastabil tetragonal fazdan daha kararlı monoklinik faza bir faz dönüşümünü içerir. Bu faz dönüşümü, zirkonyumda mikro çatlaklara ve boyutsal değişikliklere neden olabilir, bu da mekanik mukavemetini ve uzun vadeli stabilitesini tehlikeye atabilir. Tükürük, elektrolitler, enzimler, proteinler ve bakteriler içeren k ...Daha fazlası
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.
