ABSTRACTThis thesis presents diagnose and detect faults of Tennessee Eastman Process (TEP) with machine learning algorithms via Poincaré plots-based feature extraction and statistically analysis-based feature selection. The IEEEDataPort online dataset, obtained from a big plant that contains nonlinear processes from various chemical units, is utilized in this thesis. It contains measures from 52 process points in TEP with 20 dissimilar malfunction types. In this study, raw dataset and dataset that applied feature extraction and feature selection was used. Poincaré plot was applied to the datas ...Daha fazlası
ABSTRACTThe rapid development of robot technology has started to be emphasized medical robotics increasingly. The potential of robotic systems to facilitate the work of healthcare workers, minimize human errors, restore function to lost limbs, and enable operations that cannot be performed due to distance or other factors have made this field increasingly popular.Surgical robotics applications are the trend subfield of medical robotics. In these applications, it is aimed to reach the desired task with certain precision and accuracy. Therefore, performance of the control system is very crucial ...Daha fazlası
ABSTRACTThe management of public services requires an in-depth decision-making method to provide the intended functionality and service life. Municipal solid waste management is indeed one of the most challenging tasks of local municipalities and currently occupies a substantial portion of the overall municipal expenses. In this study, an entirely geographic information system (GIS) based facility siting method is developed to aid governmental bodies in the decision-making process to site such facilities. The proposed method is applied to site a transfer station (TS) in the southeastern region ...Daha fazlası
ABSTRACTAlthough gastronomy has always been a significant component of tourism products and tourist experience, with the changing tourist motivations and tourism trends gastronomy tourism has developed as a major type of alternative tourism all around the world since the 90s. Today, gastronomic values of the destinations attract many tourists and governments pay importance to gastronomy tourism as a tool in increasing for their tourism incomes. Social media is a digital platform that make individuals able to digitally interact with each other based on their interests. It has modified the way o ...Daha fazlası
ABSTRACTToday, environmentally friendly, high-strength and lightweight engineering materials are becoming increasingly important for the automotive and aviation industries. For this purpose, it is critical to combine different materials correctly and to create a reliable hybrid structure. Adhesives have a huge market share among the joining methods due to their low-stress concentration, high formulation possibility, good fatigue resistance, and sealing advantages. However, surface properties and surface treatments play an active role in determining joint performance. In this thesis, the effect ...Daha fazlası
ABSTRACTClay colloids and suspensions are distinguished from other colloidal minerals by wide ranges of application area. Clay-based colloidal systems are frequently used in various industries, including cosmetics, oil industry, medicine, pharmacy, catalysis, textiles, remediation, and food packaging. Mechanical and thermo-structural properties of these systems provide valuable information in terms of some important criteria such as shelf life, gelation process, and degradation time. The foucus point of this study is to consider the application of water-clay suspensions in drilling fluid more ...Daha fazlası
ABSTRACTOsteomyelitis is a disease in which the process of bone destruction and loss is caused by microorganisms. Osteomyelitis has an increasing incidence rate that could cause chronic and acute infections. Bone infection has caused recurrent and permanent damage in 40 of the patients. 2-5 of infections caused by medical devices used in orthopedic surgical operations are osteomyelitis. More than half of osteomyelitis cases are caused by gram-positive bacteria such as Staphylococcus aureus and Staphylococcus epidermidis. In order to prevent the occurance of osteomyelitis due to the medical dev ...Daha fazlası
ABSTRACTThe oil and natural gas reside in microscopic pores of subsurface rock layers called a reservoir rock. Besides there always at least two phases exist in oil and gas reservoirs. Therefore, the flow and displacement of oil into the production wells are influenced significantly by capillary forces. Due to the capillary and surface forces, the recovery of oil always remains at low percentages usually between 20 to 40. In order to increase the recovery factor several secondary and enhanced oil recovery techniques have been developed and implemented. The two secondary recovery methods namely ...Daha fazlası
ABSTRACTBiologically relevant molecules such as glucose, hydrogen peroxide, and dopamine are important for human body and directly affect some bodily functions. Sensitive measurement of these molecules enables humans to prevent some serious problems arising from abnormal levels of these molecules. In this thesis, glucose and dopamine were measured using screen-printed electrodes (SPE) modified with various types ofcarbon-based nanomaterials. The SPEs used here are commercially availableelectrodes in which all the necessary components (working, counter and reference electrodes) for the measurem ...Daha fazlası
ÖZETÜriner kateterler mesanesini boşaltamayan hastalarda yaygın olarak kullanılmaktadır. Fakat, kateter yüzeyleri mikroorganizma adezyonuna uygunlardır ve bu durum, ilerleyen dönemlerde çeşitli komplikasyonlara neden olmaktadır. Komplikasyonların önlenmesine yönelik çeşitli kateter malzemeleri ve farklı yüzey modifikasyonları denenmiş, fakat bu yaklaşımların çoğu başarısız olmuş ve bazıları çeşitli yan etkiler göstermiştir. Bu nedenle, komplikasyonların önlenmesi ve tedavisi için yeni yöntemlere ihtiyaç duyulmaktadır. Antimikrobiyal peptidler geniş çaplı aktivite göstermeleri, ilaç direncine n ...Daha fazlası
ABSTRACTIn this study, the effects of world governance indicators on tourism were empirically analysed, from the 2005 to 2018 period. A literature review for governance is included in the first part. The second part contains the definition of world governance indicators (WGI). In the last part, panel co-integration, and causality analysis have been carried out worldwide within 137 countries. As a result of the analysis, a long-run relationship was found only between the change in the number of tourists and the political stability - no violence index. Also, other world governance indexes voice ...Daha fazlası
ABSTRACTTorque fluctuations occur during combustion cycles of a four-stroke engine, and these fluctuations are transferred to the drivetrain of a vehicle as torsional vibration. Hence, the noise and vibration in gears clash, ping, and load change vibration cause jerky motion and reduced driving comfort. In vehicles, it is desirable to transmit this vibration generated by the engine to the drivetrain of the vehicle at the lowest level. Different technologies are used for this purpose. One of them is Dual Mass Flywheel (DMF). DMF is a complex system that includes rotational inertia, torsional st ...Daha fazlası
