Dual mass flywheel design optimization based on differential equation – neuroregression modeling approachDiferansiyel denklem – nöroregresyon modelleme yaklaşımı tabanında çift kütleli volan optimum tasarımı

Gümüş, Ümmühan

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

Olcay, Başak

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

A vehicle routing problem based scenario analysis for optimum siting of municipal solid waste transfer stations Belediye katı atık aktarma istasyonlarının optimum yerleşimi için araç rotalama problemine dayalı senaryo analizi

Höke, Milas Ceren

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

Evaluation of organic waste materials as bio-polymeric admixtures in cement based composite mortars Organik atık malzemelerin biyo-polimerik katkı olarak çimento bağlayıcılı kompozit harçlarda değerlendirilmesi

Kalkan, Şevket Onur

ABSTRACTIn this study, the effect of a new generation bio-polymeric admixture on the physical and mechanical properties of cement mortars is examined in detail. The bio-polymeric admixture is prepared by grinding egg shells, apricot kernel shells, hazelnut kernel shells, walnut kernel shells, and olive seeds in micronized sizes. The evaluation of the bio-polymeric admixtures, which are produced as wastes, among high production materials such as concrete and mortar derivative products, provides an opportunity for better disposal and management of these wastes.ÖZETBu çalışmada, yeni nesil biyopo ...Daha fazlası

The effect of fibrous dental barrier membrane on osteogenic differentiation of human mesenchymal stem cells Fibröz yapılı dental bariyer membranın insan mezenkimal kök hücrelerinin osteojenik farklılaşması üzerine etkisi

Utar, Bahar

ABSTRACTBone healing is one of the important issues in clinical areas such as oral, maxillofacial, orthopedic, and plastic surgery. Especially in the implantation process to be performed in dental applications, the structure of the jawbone and the quality of the bone density are very important for the performance of the process. In the area of tissue engineering, there are biodegradable bone implants with biocompatible synthetic polymers that give successful results in many areas. The dental barrier membrane is a synthetic bone graft based on Poly (DL-lactide). It is used in many dental applic ...Daha fazlası

Fabrication of hysteresis-free perovskite solar cells by SAM modified electrode SAM modifiyeli ITO elektrot ile histeresis östermeyen perovskit güneş hücresi üretimi

Yalçın, Eyyup

ABSTRACTEnergy has become one of the main problems of humanity after the industrial revolution and the rapid rise in world population. Most energy resources depend on fossil fuels, which causes environmental problems. Solar energy is a clean and sustainable alternative to the increasing world energy demand. In this context, perovskite solar cells (PSCs) are particularly attractive due to ability to achieve very high efficiencies. The power conversion efficiency (PCE) of PSCs has rapidly grown from 3.8 in 2009 to over 25.5 in 2022, which making it fastest advancing solar cell technology to date ...Daha fazlası

A comparison of the performances of conventional and low salinity water alternating gas injection for displacement of oil Petrolün geleneksel su gaz değişimli ötelenmesi ile az tuzlu su gaz değişimli ötelenmesi yöntemlerinin başarımlarının karşılaştırılması

Bucyanayandi, Emmanuel

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
