Akdağ, İsmail

ABSTRACTWith the development of technology, factory needs in supply chain management from production to customers have started to change. Factories have started to frequently benefit from communication systems in product tracking, warehouse stock control and supply chain management. Radio Frequency Identification (RFID) system is one of the main components of IoT technologies, where data transfer occurs wirelessly and flexibly, instead of traditional tracking and monitoring methods. RFID systems, which are automatic identification systems such as barcode systems used for the last 30 years, off ...Daha fazlası

Online learning stable adaptive controller for chaos control of bldc motor Fırçasız motorun kaos kontrolü için çevrimiçi öğrenen kararlı adaptif kontrolör

Gökçen, Alkım

ABSTRACTThis thesis presents an online learning stable robust adaptive controller design for the chaos control of the brushless direct current (BLDC) motor. The proposed adaptive controller algorithm consists of a Wiener model-based controller with a nonlinear auto-regressive moving-average (NARMA) based artificial neural network (ANN), and a Hammerstein based plant model. The developed online learning closed-loop control system providing stability and robustness might be defined as an auto-regressive moving average (ARMA) based system identification problem with partially known parameters.

The effect of antibacterial photodynamic therapy on healthy fibroblast and keratinocyte cells Antibakteriyel fotodinamik terapinin sağlıklı fibroblast ve keratinosit hücreleri üzerindeki etkisi

GÜLCE KADIKÖYLÜ

ABSTRACTAntibacterial photodynamic therapy is a treatment that occurs in the presence of light, photosensitizer and oxygen. The photosensitizer reacts with the molecular oxygen in the environment when it is stimulated by light at the appropriate wavelength, causing reactive oxygen species at the end. Reactive oxygen species show high cytotoxic effects on cells and cause necrosis or apoptosis. In recent years, the resistance of bacteria to antibiotics has caused infection treatments to become more difficult. This situation has become a threat to human and animal health. Therefore, antibacterial ...Daha fazlası

Tattoo dye removal using cold athmospheric plasma (CAP) Soğuk atmosferik plazma (SAP) kullanarak dövme boyası silme

ELİF ÇUKUR

ABSTRACTTattoo has been used as a method of self-expression of mankind since ancient times. The tattoo removal process with primitive methods is based on the process of peeling the skin layer on which the tattoo is placed. Besides being used today, laser is preferred by more people. The tattoo removal with laser is based on disintegration into smaller pieces by breaking the target tattoo pigment by absorbing the transmitted beam. It is then transferred to the nearest lymph node or disintegrated by the macrophages by means of blood or lymph circulation. The most common difficulty with laser tat ...Daha fazlası

Investigation of changes in the formation and types of non-metallic inclusions in the steel production process Çelik üretim sürecinde oluşan metal olmayan kalıntıların oluşumu ve değişimlerinin incelenmesi

Bakar, İbrahim

ABSTRACTIt is not possible to produce steel without inclusions as the process for steel production requires. Based on this fact, the researches on clean steel are concentrated on the reduction of inclusions and transformation of inclusions into harmless state by modification. The definition of steel cleanness is related to final product application. Non-metallic inclusion, in the liquid steel, causing many problems and production lost in steel production process and final application. Aluminum killed steels mostly contain Al2O3 and MnS inclusions. Al2O3 inclusions are formed during de-oxidatio ...Daha fazlası

ABSTRACTCities that have a history as a capital or an important trade center, has its own complex structure. If the historical city center was functionalized as a commercial district, it has been experienced social, cultural, environmental and economical subjects throughout centuries. This situation creates strong impacts as newly created contexts likewise political, public and architectural. These contexts generally not thought together, but they should be analyzed and investigated together for a sustainable future for the historical city centers. As a historical city center, Kemeralti-Izmir ...Daha fazlası

Estimation of annual energy production of coupled vertical-axis wind turbines in a semi-complex terrain Eşli çalışan düşey eksenli rüzgar türbinlerinin yarı karmaşık bir sahadaki yıllık enerji üretiminin değerlendirilmesi

Başer, Ferhat Cem Ferhat Cem

ABSTRACTRecent research shows that the vertical-axis wind turbines (VAWTs) can provide up to 6 - 9 times more power generation in the same footprint area when they are sited in proper configurations in contrast to horizontal-axis wind turbines (HAWT). In order to site wind turbines in a field, it is necessary to do a wind resource assessment (WRA). This assessment provide important inputs for the placement, sizing and design detailing of the wind farm. In addition to the correct determination of the site, it is also critical to place the wind turbines in the most efficient way. When the necess ...Daha fazlası

Enhancing the anticancer activity of photodynamic therapy with dual photosensitizers ıncorporated nanoparticle design Dual fotosensitizan içeren nanoparçacık tasarımı ile fotodinamik terapinin antikanser etkinliğinin geliştirilmesi

Bakay, Emel

ÖZETFotodinamik Terapi (PDT), kanser ve enfeksiyon gibi dünyanın mücadele ettiği önemli hastalıkların tedavisine yönelik bir tür ışık tedavisidir. Işığa duyarlı ve toksik olmayan ajanların hastalıklı dokuya uygulanmasından sonra hafif uygulamalar hastalıklı hücrelerin ölümünü sağlar. Bu nedenle, PDT tedavi edici ve iyileştirici bir yöntemdir. Farklı kanser türlerinin tedavisinde PDT kullanımı oldukça yaygındır. Yan etkilerinin minimal olması ve mekanizmasının doğal seyri sonucunda hastalığın direnç geliştirmesi mümkün olmadığı için birçok kanser araştırmasına konu olmuştur. Günümüzde nanoparti ...Daha fazlası
